As the majority of the global Covid fog finally started lifting in 2022, other events – and their associated risks – started to fill the headspace of C-level execs the world over. In my role, I regularly engage with CISOs in all kinds of sectors, representatives at industry bodies, and experts at analyst houses. This gives me an invaluable macroview not only of how the last 12 months have affected organizations and what CISOs are thinking about, but also how the upcoming year is shaping up.
Using this information, last year I wrote a blog summing up the nine top of mind issues I believed will most impact CISOs as we headed into 2022. Many of them still ring true now and will continue to do so, but some new concerns have risen up the agenda. Here are the topics that I think will be top of mind in 2023, and what CISOs can do to prepare.
One aspect that has come to the fore this year is the CISO’s position as ‘guardian of customers’ private data’ in the event of a breach, and their responsibilities over the level of disclosure they later provide. And here, we are not only talking about the legal duty to inform regulators, but the implicit moral duty to inform third parties, customers, etc. From my conversations this year, this whole area is getting CISOs thinking about their own personal liability more.
As a result of this, next year we could see CISOs tightening up the disclosure decision making process, focusing on quicker and greater clarity on breach impact, and even looking to include personal liability cover in cyber insurance contracts. CISOs will also likely be pushing more tabletop exercises with the executive leadership team to ask and answer questions around what is showed, to whom, and by whom.
Cyber insurance has become a newsworthy topic over the last 24 months, mainly due to the hardening of the market, as insurance products have become less profitable for underwriters and insurers’ costs have risen. But the topic will continue to be in focus as we move into 2023, with insurers demanding greater attribution – aka the science of identifying the perpetrator of a cybercrime by comparing the evidence gathered from an attack with evidence gathered from earlier attacks that have been attributed to known perpetrators to find similarities.
The need for greater attribution stems from the news that some insurers are announcing that they are not covering nation state attacks, including major marketplace for insurance and reinsurance, Lloyd’s – a topic I covered with colleague and co-author Martin Lee, in this blog earlier in the year.
Greater preparation and crystal-clear clarity of the extent to which attribution has taken place when negotiating contracts will be an essential element for CISOs going forward. For more practical advice on this topic, I also wrote a blog on some of the challenges and opportunities within the cyber liability insurance market back in June which you can read here.
Being a CISO has never been more complex. With more sophisticated attacks, scarcity of resources, the challenges of communicating effectively with the board, and more demanding regulatory drivers like the recently approved NIS2 in the EU, which includes a requirement to flag incidents that cause a significant financial implication or operational disruption to the service or to others within 24 hours.
With so much to consider, it is vital that CISOs have a clear understanding of the core elements of what they protect. Questions like ‘where is the data?’, ‘who is accessing it?’, ‘what applications is the organization using?’, ‘where and what is in the cloud?’ will continue to be asked, with an overarching need to make management of the security function more flexible and simpler for the user. This visibility will also inevitably help ease quicker decision making and less of an operational overhead when it comes to regulatory compliance, so the benefits of asking these questions are clear.
According to Forrester, the term Zero Trust was born in 2009. Since then, it has been used liberally by different cybersecurity vendors – with various degrees of accuracy. Zero Trust implementations, while being the most secure approach a firm can take, are long journeys that take multiple years for major enterprises to carry out, so it is vital that they start as they mean to go on. But it is clear from the interactions we have had that many CISOs still don’t know where to start, as we touched on in point #3.
However, that can be easier said than done in many cases, as the principles within Zero trust fundamentally turn traditional security methods on their head, from protecting from the outside in (guarding your company’s parameter from external threats) to protecting from in the inside out (guarding individual assets from all threats, both internal and external). This is particularly challenging for large enterprises with a multitude of different silos, stakeholders and business divisions to consider.
The key to success on a zero-trust journey is to set up the right governance mode with the relevant stakeholders and communicate all changes. It is also worth taking the opportunity to update their solutions via a tech refresh which has a multitude of benefits, as explained in our most recent Security Outcomes Study (volume 2).
For more on where to start check out our eBook which explores the five phases to achieving zero trust, and if you have already embarked on the journey, read our recently published Guide to Zero Trust Maturity to help you find quick wins along the way.
As with last year, ransomware continues to be the main tactical issue and concern facing CISOs. More specifically, the uncertainty around when and how an attack could be launched against the organization is a constant threat.
Increased regulation on the payment of ransomware and declaring payments is predicted, on top of the Cyber Incident Reporting for Critical Infrastructure Act of 2022 (CIRCIA), the Ransom Disclosure Act, but that doesn’t help alleviate ransomware worries, especially as this will again put the CISO in the firing line.
CISOs will continue to keep a focus on the core basics to prevent or limit the impact of an attack, and again have a closer look at how any ransomware payment may or may not be paid and who will authorize payment. For more on how executives can prepare for ransomware attacks, read this blog from Cisco Talos.
Traditionally CISOs have talked about the importance of improving security awareness which has resulted in the growth of those test phishing emails we all know and love so much. Joking aside, there is increased discussion now about the limited impact of this approach, including this in depth study from the computer science department of ETH Zurich.
The study, which was the largest both in terms of scale and length at time of publishing, revealed that ‘embedded training during simulated phishing exercises, as commonly deployed in the industry today, does not make employees more resilient to phishing, but instead it can have unexpected side effects that can make employees even more susceptible to phishing’.
For the most effective security awareness, culture is key. This means that everyone should see themselves as part of the security team, like the approach that has been taken when approaching the issue of safety in many high-risk industries. In 2023, CISOs will now be keen to bring about a change to a security culture by making security inclusive, looking to create security champions within the business unit, and finding new methods to communicate the security message.
Last year, we talked about preparing for the ‘great resignation’ and how to prevent staff leaving as WFH became a norm rather than an exception. In the past year, the conversations I have had have altered to focus on how to ensure recruitment and retention of key staff within the business by ensuring they work in an environment that supports their role.
Overly restrictive security practices, burdensome security with too many friction points, and limitations around what resources and tools can be used may deter the best talent from joining – or indeed staying – with an organization. And CISOs don’t need that extra worry of being the reason behind that kind of ‘brain drain’. So, security will need to focus on supporting the introduction of flexibility and the ease of user experience, such as passwordless or risk-based authentication.
Just when we thought it was safe to go back into the organization with MFA protecting us, along came methods of attack that rely on push-based authentication vulnerabilities including:
There has been a lot written about this kind of technique and how it works (including guidance from Duo) due to some recent high-profile cases. So, in the forthcoming year CISOs will look to update their solutions and introduce new ways to authenticate, along with increased communications to users on the topic.
This issue was highlighted again this year driven by regulations in different sectors such as the UK Telecoms (Security) Act which went live in the UK in November 2022 and the new EU regulation on digital operational resilience for financial services firms (DORA), which the European Parliament voted to adopt, also in November 2022. Both prompt greater focus on compliance, more reporting and understanding the dependency and interaction organizations have with the supply chain and other third parties.
CISOs will focus on obtaining reassurance from third parties as to their posture and will receive a lot of requests from others about where their organization stands, so it is crucial more robust insight into third parties is gained, documented, and communicated.
When writing this blog, and comparing it to last year’s, the 2023 top nine topics fit into three categories. Some themes make a reappearance, seem to repeat themselves such as the need to improve security’s interaction with users and the need to keep up to date with digital change. Others appear as almost incremental changes to current capabilities such as an adjusted approach to MFA to cope with push fatigue. But, perhaps one of the most striking differences to previous years is the new focus on the role of the CISO in the firing line and the personal impact that may have. We will of course continue to monitor all changes over the year and lend our viewpoint to give guidance. We wish you a secure and prosperous new year!

An attacker can use the email module of SquarePhish to send a malicious QR code email to a victim. The default pretext is that the victim is required to update their Microsoft MFA authentication to continue using mobile email. The current client ID in use is the Microsoft Authenticator App.
By sending a QR code first, the attacker can avoid prematurely starting the OAuth Device Code flow that lasts only 15 minutes.
The victim will then scan the QR code found in the email body with their mobile device. The QR code will direct the victim to the attacker controlled server (running the server module of SquarePhish), with a URL paramater set to their email address.
When the victim visits the malicious SquarePhish server, a background process is triggered that will start the OAuth Device Code authentication flow and email the victim a generated Device Code they are then required to enter into the legitimate Microsoft Device Code website (this will start the OAuth Device Code flow 15 minute timer).
The SquarePhish server will then continue to poll for authentication in the background.

All of the applicable settings for execution can be found and modified via the settings.config file. There are several pieces of required information that do not have a default value that must be filled out by the user: SMTP_EMAIL, SMTP_PASSWORD, and SQUAREPHISH_SERVER (only when executing the email module). All configuration options have been documented within the settings file via in-line comments.
Note: The SQUAREPHISH_ values present in the 'EMAIL' section of the configuration should match the values set when running the SquarePhish server.
Currently, the pre-defined pretexts can be found in the pretexts folder.
To write custom pretexts, use the existing template via the pretexts/iphone/ folder. An email template is required for both the initial QR code email as well as the follow up device code email.
Important: When writing a custom pretext, note the existence of %s in both pretext templates. This exists to allow SquarePhish to populate the correct data when generating emails (QR code data and/or device code value).
There are several HTTP response headers defined in the utils.py file. These headers are defined to override any existing Flask response header values and to provide a more 'legitimate' response from the server. These header values can be modified, removed and/or additional headers can be included for better OPSEC.

}Attackers specifically craft business email compromise (BEC) and phishing emails using a combination of malicious techniques, expertly selected from an ever-evolving bag of tricks. They’ll use these techniques to impersonate a person or business that’s well-known to the targeted recipient and hide their true intentions, while attempting to avoid detection by security controls.
As a result of the requisite expertise needed to combat these complex attacks, email security has traditionally been siloed away in disparate teams and security controls. Practitioners are buried under an ever-growing pile of RFCs, requiring extensive domain-specific knowledge, unending vigilance, and meticulous manual interventions, such as tweaking trust levels and cultivating allow/block lists with IPs, domains, senders, and vendors.
Cisco Secure Email Threat Defense is leading the industry forward with a major shift, elevating email security into a new era; where administration will consist of merely associating specific business risks with the appropriate due diligence response required to remediate against them.
Email Threat Defense has introduced a new Threat Profile that provides the customer with deep insights into the specific business risks of individual email threats and the confidence to act quickly. This new visualization is powered by a new patent-pending threat detection engine. This engine leverages intelligence distilled from Talos global-scale threat research across a massive volume of email traffic into machine learning, behavioral modeling, and natural language understanding.
The detection engine granularly identifies specific underlying threat techniques utilized in the message by the attacker. The identified techniques provide the full context of the threat message as the supporting foundation for the engine to determine threat categorization and the specific risk to the business. These malicious Techniques, together with the threat category and specific business risk, are used to populate the Threat Profile.
Each message’s Threat Profile is identified in real-time, automatically remediated per policy, and surfaced directly to the operator in the message detail views, providing deep contextual insights into the attacker’s intent and the associated risks to the business. As part of a larger Extended Detection and Response (XDR) strategy, the actionable intelligence in Email Threat Defense is integrated with the wider enterprise orchestration of security controls via SecureX, easing the operational burden by decreasing your mean time to remediation (MTTR).
Email Threat Defense delivers a distinct understanding of malicious messages, the most vulnerable targets within the organization, and the most effective means of protecting them from phishing, scams, and BEC attacks. With a clean design and core focus on simplifying administration, Email Threat Defense deploys in minutes to strengthen protection of your existing Microsoft 365 Exchange Online platform against the most advanced email threats.

Oh, the scammers online are frightful, and the deals they offer seem delightful. No matter what you think you know, let it go, let it go, let it go (to the tune of 1945’s Let it Snow by Vaughn Monroe with the Norton Sisters).
‘Tis the season to find ourselves awash in good tidings and, well, consumerism. While it’s only partly tongue in cheek, we must be honest with ourselves. We spend a lot of money online. Often, we find ourselves leaving things to the last minute and hope that the delivery folks can make the magic happen and send us all the widgets and grapple grommets while we surf the Internet from the safety of our sofas with coffee in hand.
But, not every deal is what it appears to be. Scammers are always lurking in the void of the Internet waiting for a chance to fleece the unexpecting from their hard-earned money. This can manifest itself to the unsuspecting in many ways. There are shipping frauds, gift card giveaways and vishing (phone-based scams).
Scams tend to rely on generating a false sense of urgency. The shipping scam emails often show up in our inboxes as a warning about a missed or delayed package that will be sent back to the point of origin if we don’t answer quickly. Of course, this requires a payment to receive the fictitious package.
These types of shipping scam emails are quite effective this time of year when more often than naught many people have enough orders coming to their house to make a fort with the empty boxes.
The other kinds of attacks are the gift card scams and vishing. The first of which taps into the sense of excitement that a person might receive something for free. “Fill out this form with your credit card information for a chance to win a $200 gift card.” Sadly, this attack works well for older generations for which giveaways were more common and they aren’t as accustomed to spotting digital swindlers.
The last scam that we will tackle here is often labeled as vishing or voice phishing. This is a method whereby the attackers call a victim and attempt to convince their target that they need to do something which will lead to the exposure of financial information while pressuring the victim to think if they don’t act quickly that they will miss an opportunity for personal gain.
Unfortunately, the aforementioned scams really bring in a lot of return for the criminal element. In 2021, over 92,000 victims over the age of 60 reported losses of $1.7 billion. This represents a 74 percent increase in losses over losses reported in 2020.
One additional scam that plays on the heart strings is the romance scams. A lot of single people find themselves lonely during the holidays and can be manipulated into thinking that they’ve found a romantic match. But this can drain the bank accounts as well.
In 2021, the IC3 received reports from 7,658 victims who experienced over $432 million in losses to Confidence Fraud/Romance scams. This type of fraud accounts for the highest losses reported by victims over the age of 60.
All these attacks prey on people’s emotional responses. So, how do we prepare ourselves? We need to make knowledge a capability and arm ourselves with information that will help us avoid being taken advantage of by criminals.
Passwords are a significant exposure. They are the digital equivalent of a house key. A password will work for anyone that has access to it. We need to utilize technologies such as multi-factor authentication (MFA) on websites where it is possible to do so. So even if bad actors have our password, the victim still needs to approve the login.
If we don’t have the option to use MFA it would be an excellent idea to make use of a password manager. This is a way to safely store passwords and not fall into the trap of reusing passwords on multiple sites. Attackers bank on human nature and if we use the same credentials on multiple sites there is a high possibility that the criminals could gain access to other sites if they compromise just one.
I’m usually one to eschew the practice of New Year’s resolutions but I’ll make an exception. Keep a keen sense about yourselves whenever you receive an email or SMS that you were not expecting. If a deal is too good to be true then, well, it most likely is a scam. If you’re in doubt, try to look up the phone number, email address, person or “organization” offering the “deal.” More often than not, you’ll find lots of people reporting that it’s a scam.
Rather than being visited by the three ghosts of holiday scams, make sure you and your loved ones are prepared for a happy holiday and a prosperous New Year.

Watch ThreatWise TV: Explorations in the spam folder
The spam folder: that dark and disregarded corner of every email account, full of too-good-to-be-true offers, unexpected shipments, and supposedly free giveaways.
You’re right to ignore this folder; few good things come from exploring it. But every once in a while one of these misleading, and sometimes malicious, emails manages to evade the filters that normally siphon them off, landing them in your inbox instead.
Fortunately, it’s easy enough to spot these emails if you know what to look for. We’ve investigated this folder once before, showcasing a variety of scams. With the holiday season in full swing, we thought this would be a good time to revisit how scammers are trying to trick unsuspecting users.
The holiday season is traditionally a time when this type of activity increases, and this year is no different. According to research published by credit reporting agency TransUnion, the average daily number of suspected digital fraud attempts was up 82 percent globally between Thanksgiving and Cyber Monday (Nov 24–Nov 28) compared to the rest of the year (Jan 1–Nov 23) and 127 percent higher for transactions originating in the US.
This level of activity makes it all the more important to be aware of these scams. With that in mind, let’s dive into the spam folder to get a picture of the types of campaigns currently circulating.
While much of the spam circulating is innocuous, many emails are phishing attempts, and some are indeed malicious. To explore these scams, we used a dedicated computer, segmented from the rest of the network, and leveraged Cisco Secure Malware Analytics to safely open the emails before clicking on links or opening attachments. The point being, we do not recommend doing this at home.
By far, the largest category of spam we saw were surveys scams. According to these emails, if you fill out a simple survey you’ll receive “exclusive offers” such as gift cards, smartphones, smart watches, power drills, or even pots and pans.
There are even some campaigns that specifically target the holiday shopping season.
Clicking the links in these emails takes the recipient to sites where they are asked to fill out a survey.
These pages often include fake testimonials that say how easy the survey is and what they did with their free gift.
The surveys are straightforward, comprising 10-20 simple questions that cover demographic information and shopping habits.
After the survey is completed, these sites offer the choice of a handful of rewards. All the recipient must do is pay for shipping. They are then brought to a page where they can fill out shipping and payment information, and the reward is supposedly shipped.
However, the attempts to make payment often appear to fail, or the recipient is informed that the prize is no longer available.
An unsuspecting user may simply give up at this point, disappointed that they won’t be getting their free gift. What they may not be aware of, is that they have just given their credit card details away in a phishing scam.
In their 2021 Internet Crime Report, the Internet Crime Complaint Center (IC3) said that Non-Payment / Non-Delivery scams such as these led to more than $337 million in losses, up from $265 million in 2020. Credit card fraud amounted to $172 million in 2021 and has been climbing continuously at a conservative rate of 15-20 percent since 2019.
According to Cisco Umbrella, many of the sites asking for credit card details are known phishing sites, or worse, host malware.
Another topic that we covered the last time we explored these types of scams was package delivery spam. These continue to circulate today. There are a variety of shipping companies impersonated in these campaigns, and some generic ones as well.
Many of these campaigns claim that a package could not be delivered. If the recipient clicks on a link in an email, they’re brought to a web page that explains that there are outstanding delivery fees that need to be paid.
The recipient is further enticed by suggestions that the package contains a big-ticket item, such as an iPhone or iPad Pro. All the recipient is required to do is enter their credit card details to cover the shipping.
While no outright malicious activity was detected while examining these emails in Secure Malware Analytics, several suspicious behaviors were flagged. Chances are the bad actors behind these campaigns are phishing for credit card details.
Sometimes the simplest approaches can work just as well as the flashiest. This certainly holds true with spam campaigns, given the prominence of plain-text messages.
The topics covered in such emails run the gamut, including medical cures, 419 scams, romance and dating, pharmaceuticals, weight loss, and many of the scam types we’ve already covered. Many of these link to phishing sites, though some attempt to establish a dialog with the recipient, tricking them into sending the scammers money.
The IC3 report says that victims of confidence fraud and romance scams lost $956 million collectively, which is up from $600 million in 2020. Healthcare fraud, such as the miracle pills and prescriptions scams, resulted in $7 million in losses in 2021, but nearly $30 million in 2020. While these types of scams seem generic and easily spotted, they still work, and so it’s important to be aware and avoid them.
Many emails hitting the spam box attempt to trick users of various services into believing that there is a problem with their account. The problems cover all sorts of services, including streaming platforms, email providers, antivirus subscriptions, and even public records.
If the links are clicked, the recipient is presented with landing pages that mimic the respective services. Any details that are entered will likely be phished, leading to account takeover and/or access to personal records. However, some domains encountered in these cases may do more than just steal information, they could deliver malware too.
Another frequently encountered scam surrounds billing. Many of these appear to be unexpected bills for services the recipient never purchased.
These emails include attachments that are designed to look like official invoices. Interestingly, most of the attachments that we looked at this time were harmless. The goal is to get the recipient to call what appears to be a toll-free number.
While we haven’t called any of these numbers, the experience usually unfolds like a standard customer service call. In the end the “agents” simply claim the charges—which never existed in the first place—have been removed. Meanwhile the scammers steal any personal or financial information provided during the call.
While most billing scams we encountered played out as described above, a few did indeed contain malware.
In this example, the email appears to come from an internet service provider, informing us that our monthly bill is ready.
An invoice appears to be attached, stored within a .zip file. If the recipient opens it and double clicks the file within, a command prompt appears.
This may seem unusual to the recipient, especially since no invoice appears, but by this point it’s too late. The file contains a script that launches PowerShell and attempts to download a remote file.
While the remote file was no longer available at the time of analysis, there is a high likelihood it was malicious. But even though we were unable to determine its contents, Secure Malware Analytics flagged the script execution as malicious.
Knowing about prevalent scams, especially during the holiday season, is a first step in guarding against them. Granted the bad actors who distribute these spam campaigns do everything they can to make their scams look legitimate.
Fortunately, there are several things that you can do to identify scams and defend against them:
But even the best of us can be fooled, and when overseeing a large operation it’s more a matter of when, rather than if, someone clicks on the wrong link. There are elements of the Cisco Secure portfolio that can help for when the inevitable happens.

Holding the door for someone might open the way to a cyberattack. For anyone who works in a secure building or workplace, they might want to rethink that courtesy. The hackers and thieves behind piggybacking and tailgating attacks count on it.
Piggyback and tailgating attacks occur when an unauthorized person gains access to a restricted workplace, one that requires some form of ID to enter. While quite similar, these attacks have an important difference:
In both cases, these unauthorized entries can put businesses and organizations at risk. They give potential bad actors all kinds of access to sensitive information and devices.
Trade secrets get stolen this way, as does customer information. In yet more malicious cases, bad actors might gain entry with the intent of sabotaging technology or hijacking a network. And of course, bad actors might do harm to people or property.
Businesses and organizations that find themselves at risk include those that:
Different businesses and organizations have different forms of security in place. You might be among the many who use a smart badge or some form of biometric security to enter a building or certain areas within a building.
However, determined bad actors will look for ways around these measures. With piggyback and tailgating attacks, it’s far easier for them to follow someone into a workplace than it is to break into a workplace.
Bad actors will simply walk in when someone holds the door for them. It’s as simple as that. Additionally, they’ll try several different tricks by:
In all, piggybacking and tailgating attacks rely on social engineering—playing off people’s innate courtesy, willingness to help, or even discomfort with conflict. Essentially, the attacker manipulates human nature.
A good portion of prevention falls on the owner of the building, whether that’s a business, organization, or a landlord. It falls on them to install security hardpoints like badge scanners, keypad locks, biometric scanners, and so on to keep the property secure. Moreover, employers owe it to themselves and their employees to train them on security measures.
Yet you can take further steps to prevent a piggybacking or tailgating attack on your workplace. Some steps include:
Also consider the security of your devices or any other sensitive information you work with. If a bad actor slips into your workplace, you can take other steps to prevent theft or damage.
Some aspects of piggybacking and tailgating prevention seem like they go against our better nature. We want to be kind, helpful, and sometimes we’d simply rather avoid confrontation. Again, piggybackers and tailgaters count on that. Yet a door is only as secure as the person who uses it—or who opens it for someone else.

Something looks a little … sketchy. Is that website safe or unsafe?
Nowadays, it can take a bit 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 “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.
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 a strong attention to detail—or the creative capabilities to create a good-looking website in the first place.
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 on example, and we do the same here at McAfee. Reviewing these lists can help you spot an imposter site.
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.
A screen full of links insisting you to 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.
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.)
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.
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.

What color jersey will you be sporting this November and December? The World Cup is on its way to television screens around the world, and scores of fans are dreaming of cheering on their team at stadiums throughout Qatar. Meanwhile, cybercriminals are dreaming of stealing the personally identifiable information (PII) of fans seeking last-minute vacation and ticket deals.
Don’t let the threat of phishers and online scammers dampen your team spirit this World Cup tournament. Here are three common schemes cybercriminals will likely employ and a few tips to help you dribble around their clumsy offense and protect your identity, financial information, and digital privacy.
Phishers will be out in full force attempting to capitalize on World Cup fever. People wrapped up in the excitement may jump on offers that any other time of the year they would treat with skepticism. For example, in years past, fake contests and travel deals inundated email inboxes across the world. Some companies do indeed run legitimate giveaways, and cybercriminals slip in their phishing attempts among them.
If you receive an email or text saying that you’re the winner of a ticket giveaway, think back: Did you even enter a contest? If not, treat any “winner” notification with skepticism. It’s very rare for a company to automatically enter people into a drawing. Usually, companies want you to act – subscribe to a newsletter or engage with a social media post, for example – in exchange for your entry into their contest. Also, beware of emails that urge you to respond within a few hours to “claim your prize.” While it’s true that real contest winners must reply promptly, organized companies will likely give you at least a day if not longer to acknowledge receipt.
Traveling is rarely an inexpensive endeavor. Flights, hotels, rental cars, dining costs, and tourist attraction admission fees add up quickly. In the case of this year’s host country, Qatar, there’s an additional cost for American travelers: visas.
If you see package travel deals to the World Cup that seem too good to pass up … pass them up. Fake ads for ultra-cheap flights, hotels, and tickets may appear not only in your email inbox but also on your social media feed. Just because it’s an ad doesn’t mean it comes from a legitimate company. Legitimate travel companies will likely have professional-looking websites with clear graphics and clean website copy. Search for the name of the organization online and see what other people have to say about the company. If no search results appear or the website looks sloppy, proceed with caution or do not approach at all.
Regarding visas, be wary of anyone offering to help you apply for a visa. There are plenty of government-run websites that’ll walk you through the process, which isn’t difficult as long as you leave enough time for processing. Do not send your physical passport to anyone who is not a confirmed government official.
Even fans who’ve given up on watching World Cup matches in person aren’t out of the path of scams. Sites claiming to have crystal clear streams of every game could be malware spreaders in disguise. Malware and ransomware targeting home computers often lurk on sketchy sites. All it takes is a click on one bad link to let a cybercriminal or a virus into your device.
Your safest route to good-quality live game streams is through the official sites of your local broadcasting company or the official World Cup site. You may have to pay a fee, but in the grand scheme of things, that fee could be a lot less expensive than replacing or repairing an infected device.
Here’s an excellent rule to follow with any electronic correspondence: Never send anyone your passwords, routing and account number, passport information, or Social Security Number. A legitimate organization will never ask for your password, and it’s best to communicate any sensitive financial or identifiable information over the phone, not email or text as they can easily fall into the wrong hands. Also, do not wire large sums of money to someone you just met online.
Don’t let scams ruin your enjoyment of this year’s World Cup! With these tips, you should be able to avoid the most common schemes but to boost your confidence in your online presence, consider signing up for McAfee+. Think of McAfee+ as the ultimate goalkeeper who’ll block any cybercriminals looking to score on you. With identity monitoring, credit lock, unlimited VPN and antivirus, and more, you can surf safely and with peace of mind.

Smishing and vishing are scams where criminals attempt to get users to click a fraudulent link through a phone text message, email, or voicemail. These scams are becoming increasingly popular as cybercriminals try to take advantage of people who are more likely to fall for them, such as those who aren’t as familiar with technology or who may be experiencing a crisis.
Be aware that cybercrime and hacking can happen to anyone. Criminals are always looking for new ways to exploit people, and they know that others may not be cautious or recognize the warning signs of phishing scams when using the internet. That’s why it’s important to be aware of the different types of cybercrime and how to protect yourself.
This article discusses how to protect yourself from smishing attempts and scams where criminals try to get you to click on a fraudulent link or respond to their voicemail message to steal your personal data.
Most people are familiar with phishing scams, where scammers try to trick you into giving them your personal or financial information by pretending to be a legitimate company or organization. But have you ever heard of smishing or vishing?
Smishing is a type of phishing scam where attackers send SMS messages (or text messages) to trick victims into sharing personal information or installing malware on their devices. Vishing is almost identical to smishing, except cybercriminals use VoIP (Voice over IP) to place phone calls to trick victims instead of SMS (short message service) messages.
Smishing messages often appear to be from a legitimate source, such as a well-known company or government agency. It may even include urgent language or threats in an effort to get victims to act quickly. In some cases, the message may also include a link that directs victims to a fake website where they are prompted to enter personal information or download malware.
Here are some examples of smishing text messages hackers use to steal your personal details:
If you fall for a smishing scam, you could end up giving away your personal information or money. Cybercriminals use smishing messages to get personal and financial information, like your credit card number or access to your financial services.
For example, one type of smishing scam is when you get a text message that looks like it’s from your bank. The message might say there’s been suspicious activity on your account and that you need to click on a link to verify your identity. If you do click on the link, you’ll be taken to a fake website where you’ll be asked to enter your banking information. Once the scammers have your login information, they have access to clean out your account.
Smishing scams can be very difficult to spot, but there are some telltale signs to look for and steps to take to protect yourself.
One of the easiest ways to protect yourself from smishing scams is to be able to recognize the signs of a smishing text message. Here are some tips:
While you can’t avoid smishing attacks altogether, you can block spam text messages you receive on your mobile phone. iPhone and Android have cybersecurity tools like spam filters and phone number blocking to help protect you from phishing attacks and malicious links.
To set up spam filters on your iPhone:
To set up spam filters on your Android mobile device:
McAfee Mobile Security is a mobile security app that helps protect your phone from malware, phishing attacks, and other online threats. McAfee Mobile Security is available for Android and iOS cell phones.

Going beyond the hype, passwordless authentication is now a reality. Cisco Duo’s passwordless authentication is now generally available across all Duo Editions.
“Cisco Duo simplifies the passwordless journey for organizations that want to implement phishing-resistant authentication and adopt a zero trust security strategy.”
—Jack Poller, Senior Analyst, ESG
We received tremendous participation and feedback during our public preview, and we are now excited to bring this capability to our customers and prospects.
“Over the last few years, we have increased our password complexities and required 2FA wherever possible. With this approach, employees had more password lock outs, password fatigue, and forgetting their longer passwords due to password rotations. With Duo Passwordless, we are excited to introduce this feature to our employees to keep our password complexities in place and leverage different Biometric options whether that is using their mobile device, Windows Hello, or a provided FIDO security key.
The Duo Push for passwordless authentication feature is simple and easy and introduces a more pleasant experience overall. Using Duo’s device insight and application policies, we are able to leverage and verify the security of the mobile devices before the device is allowed to be used. To top it off, Duo is connected to our SIEM and our InfoSec team is able to review detailed logs and setup alerts to be able to keep everything secure.”
—Vice President of IT, Banking and Financial Services Customer
As with any new technology, getting to a completely passwordless state will be a journey for many organizations. We see customers typically starting their passwordless journey with web-based applications that support modern authentication. To that effect, Duo’s passwordless authentication is enabled through Duo Single Sign-On (SSO) for federated applications. Customers can choose to integrate their existing SAML Identity provider such as Microsoft (ADFS, Azure), Okta or Ping Identity; or choose to use Duo SSO (Available across all Duo editions).
“Password management is a challenging proposition for many enterprises, especially in light of BYOD and ever increasing sophistication of phishing schemes. Cisco aims to simplify the process with its Duo passwordless authentication that offers out-of-box integrations with popular single sign-on solutions.”
—Will Townsend, Vice President & Principal Analyst, Networking & Security, Moor Insights & Strategy
Duo offers a flexible choice of passwordless authentication options to meet the needs of businesses and their use cases. This includes:
No matter which authentication option you choose, it is secure and inherently multi-factor authentication. We are eliminating the need for the weak knowledge factor (something you know – passwords) which are shared during authentication and can be easily compromised. Instead, we are relying on stronger factors, which are the inherence factor (something you are – biometrics) and possession factor (something you have – a registered device). A user completes this authentication in a single gesture without having to remember a complex string of characters. This significantly improves the user experience and mitigates the risk of stolen credentials and man-in-the-middle (MiTM) attacks.
FIDO2 authentication is regarded as phishing-resistant authentication because it:
Using Duo with FIDO2 authenticators enables organizations to enforce phishing-resistant MFA in their environment. It also complies with the Office of Management and Budget (OMB) guidance issued earlier this year in a memo titled “Moving the U.S. Government Towards Zero Trust Cybersecurity Principles”. The memo specifically requires agencies to use phishing-resistant authentication method.
We understand that getting the IT infrastructure ready to support FIDO2 can be expensive and is typically a long-term project for organizations. In addition, deploying and managing 3rd party security keys creates IT overhead that some organizations are not able to undertake immediately.
Alternatively, using Duo Push for passwordless authentication is an easy, cost effective to get started on a passwordless journey for many organizations, without compromising on security.
We have incorporated security into the login workflow to bind the browser session and the device being used. So, organizations get the same benefits of eliminating use of stolen credentials and mitigation of phishing attacks. To learn more about passwordless authentication with Duo Push, check out our post: Available Now! Passwordless Authentication Is Just a Tap Away.
In addition to going passwordless, many organizations are looking to implement zero trust access in their IT environment. This environment typically is a mix of modern and legacy applications, meaning passwordless cannot be universally adopted. At least not until all applications can support modern authentication.
Additionally, organizations need to support a broad range of use cases to allow access from both managed and unmanaged (personal or 3rd party contractor) devices. And IT security teams need visibility into these devices and the ability to enforce compliance to meet the organization’s security policies such as ensuring that the operating system (OS) and web browser versions are up to date. The importance of verifying device posture at the time of authentication is emphasized in the guidance provided by OMB’s zero trust memorandum – “authorization systems should work to incorporate at least one device-level signal alongside identity information about the authenticated user.”
Duo can help organizations adopt a zero trust security model by enforcing strong user authentication across the board either through passwordless authentication where applicable or thought password + MFA where necessary, while providing a consistent user experience. Further, with capabilities such as device trust and granular adaptive policies, and with our vision for Continuous Trusted Access, organizations get a trusted security partner they can rely on for implementing zero trust access in their environment.

I’m sure you’ve seen them — emails or messages that sound alarming and ask you to act quickly. We live in a digital world that produces hundreds of messages and alerts every day. It’s often hard to determine the validity of a suspicious message or phishing email. Whether you are an administrator, or an end-user, it can be overwhelming to accurately identify a malicious message. When in doubt, here are some questions you should ask yourself:
Is the message from a legitimate sender?
Do I normally receive messages from this person?
If there’s a link, can I tell where it’s sending me?
Attackers continue to evolve their methods, and they’re highly educated on the defenses they come up against in the wild. They’ll craft messages that do not involve any traditional indicators of compromise, such as domains, IP address, or URL links. They’ll also start their attacks by sending messages as an initial lure to establish trust, before sending an email with altered invoice or one claiming to be a helpless employee attempting to get their payroll fixed.
Phishing is a socially-based attack type, one where the threat actors focus on human behavior. When these attacks target organizations, there are multiple levels of attack at play. One that focuses on behavioral patterns and workflow, and the other centers on the victim’s emotional boundaries, such as targeting their desire to help others. You see this pattern frequently in Business Email Compromise (BEC) attacks.
Below, we’ve placed an example of a lure, which will test the victim to see if there is a means to quickly establish trust. Here, the threat actor is pretending to be the Chief Financial Officer (CFO) of the victim’s organization. If the lure is successful, then the threat actor will progress the attack, and often request sensitive records or wire transfers. Notice that in the email headers, the person pretending to be the CFO is using a Gmail account, one that was likely created just for this attack. The message is brief, stresses importance and urgency, and requests assistance, playing on the victim’s workflow and desire to help an executive or someone with authority.
The example below is a simplified one, to be sure, but the elements are legitimate. Daily, emails like this hit the inboxes of organizations globally, and the attackers only need to locate a single victim to make their efforts payout.
In the FBI / IC3 2021 Internet Crime Report, there were nearly 20,000 Business Email Compromise complaints filed, with an adjusted loss of nearly 2.4 billion dollars. While spoofing the identity of an executive is certainly one way to conduct a BEC attack, the FBI says that threat actors have started leveraging the normality of hybrid-work to target meeting platforms to establish trust and conduct their crimes. When successful, the funds from the fraudulent wire transfers are moved to crypto wallets and the funds dispersed, making recovery harder.
So as an end user what can you do to protect your organization? Be mindful anytime you receive an urgent call to action, especially when the subject involves money. If your workflow means that you regularly receive these types of requests from the specific individual, verify their identity and the validity of the request using another channel of communication, such as in person or via phone. If you do validate their identity via the phone, take care to avoid calling any numbers listed in the email.
Cisco Secure Email helps stop these types of attacks by tracking user relationships and threat techniques. These techniques often include account takeover, spoofing and many more. Using an intent-based approach allows Secure Email to detect and classify business email compromises and other attacks, so administrators are empowered to take a risk-based approach to stopping these threats.

One of the oldest tricks in the cybercrime playbook is phishing. It first hit the digital scene in 1995, at a time when millions flocked to America Online (AOL) every day. And if we know one thing about cybercriminals, it’s that they tend to follow the masses. In earlier iterations, phishing attempts were easy to spot due to link misspellings, odd link redirects, and other giveaways. However, today’s phishing tricks have become personalized, advanced, and shrouded in new disguises. So, let’s take a look at some of the different types, real-world examples and how you can recognize a phishing lure.
Every day, users get sent thousands of emails. Some are important, but most are just plain junk. These emails often get filtered to a spam folder, where phishing emails are often trapped. But sometimes they slip through the digital cracks, into a main inbox. These messages typically have urgent requests that require the user to input sensitive information or fill out a form through an external link. These phishing emails can take on many personas, such as banking institutions, popular services, and universities. As such, always remember to stay vigilant and double-check the source before giving away any information.
A sort of sibling to email phishing, link manipulation is when a cybercriminal sends users a link to malicious website under the ruse of an urgent request or deadline. After clicking on the deceptive link, the user is brought to the cybercriminal’s fake website rather than a real or verified link and asked to input or verify personal details. This exact scenario happened last year when several universities and businesses fell for a campaign disguised as a package delivery issue from FedEx. This scheme is a reminder that anyone can fall for a cybercriminals trap, which is why users always have to careful when clicking, as well as ensure the validity of the claim and source of the link. To check the validity, it’s always a good idea to contact the source directly to see if the notice or request is legitimate.
Corporate executives have always been high-level targets for cybercriminals. That’s why C-suite members have a special name for when cybercriminals try to phish them – whaling. What sounds like a silly name is anything but. In this sophisticated, as well as personalized attack, a cybercriminal attempts to manipulate the target to obtain money, trade secrets, or employee information. In recent years, organizations have become smarter and in turn, whaling has slowed down. Before the slowdown, however, many companies were hit with data breaches due to cybercriminals impersonating C-suite members and asking lower-level employees for company information. To avoid this pesky phishing attempt, train C-suite members to be able to identify phishing, as well as encourage unique, strong passwords on all devices and accounts.
Just as email spam and link manipulation are phishing siblings, so too are whaling and spear-phishing. While whaling attacks target the C-suite of a specific organization, spear-phishing rather targets lower-level employees of a specific organization. Just as selective and sophisticated as whaling, spear-phishing targets members of a specific organization to gain access to critical information, like staff credentials, intellectual property, customer data, and more. Spear-phishing attacks tend to be more lucrative than a run-of-the-mill phishing attack, which is why cybercriminals will often spend more time crafting and obtaining personal information from these specific targets. To avoid falling for this phishing scheme, employees must have proper security training so they know how to spot a phishing lure when they see one.
With so many things to click on a website, it’s easy to see why cybercriminals would take advantage of that fact. Content spoofing is based on exactly that notion – a cybercriminal alters a section of content on a page of a reliable website to redirect an unsuspecting user to an illegitimate website where they are then asked to enter personal details. The best way to steer clear of this phishing scheme is to check that the URL matches the primary domain name.
When users search for something online, they expect reliable resources. But sometimes, phishing sites can sneak their way into legitimate results. This tactic is called search engine phishing and involves search engines being manipulated into showing malicious results. Users are attracted to these sites by discount offers for products or services. However, when the user goes to buy said product or service, their personal details are collected by the deceptive site. To stay secure, watch out for potentially sketchy ads in particular and when in doubt always navigate to the official site first.
With new technologies come new avenues for cybercriminals to try and obtain personal data. Vishing, or voice phishing, is one of those new avenues. In a vishing attempt, cybercriminals contact users by phone and ask the user to dial a number to receive identifiable bank account or personal information through the phone by using a fake caller ID. For example, just last year, a security researcher received a call from their financial institution saying that their card had been compromised. Instead of offering a replacement card, the bank suggested simply blocking any future geographic-specific transactions. Sensing something was up, the researcher hung up and dialed his bank – they had no record of the call or the fraudulent card transactions. This scenario, as sophisticated as it sounds, reminds users to always double-check directly with businesses before sharing any personal information.
As you can see, phishing comes in all shapes and sizes. This blog only scratches the surface of all the ways cybercriminals lure unsuspecting users into phishing traps. The best way to stay protected is to invest in comprehensive security and stay updated on new phishing scams.
The post The Seven Main Phishing Lures of Cybercriminals appeared first on McAfee Blog.
It’s hard to imagine a world without cellphones. Whether it be a smartphone or a flip phone, these devices have truly shaped the late 20th century and will continue to do so for the foreseeable future. But while users have become accustomed to having almost everything they could ever want at fingertips length, cybercriminals were busy setting up shop. To trick unsuspecting users, cybercriminals have set up crafty mobile threats – some that users may not even be fully aware of. These sneaky cyberthreats include SMSishing, fake networks, malicious apps, and grayware, which have all grown in sophistication over time. This means users need to be equipped with the know-how to navigate the choppy waters that come with these smartphone-related cyberthreats. Let’s get started.
If you use email, then you are probably familiar with what phishing is. And while phishing is commonly executed through email and malicious links, there is a form of phishing that specifically targets mobile devices called SMSishing. This growing threat allows cybercriminals to utilize messaging apps to send unsuspecting users a SMSishing message. These messages serve one purpose – to obtain personal information, such as logins and financial information. With that information, cybercriminals could impersonate the user to access banking records or steal their identity.
While this threat was once a rarity, its the rise in popularity is two-fold. The first aspect is that users have been educated to distrust email messages and the second is the rise in mobile phone usage throughout the world. Although this threat shows no sign of slowing down, there are ways to avoid a cybercriminal’s SMSishing hooks. Get started with these tips:
Public and free Wi-Fi is practically everywhere nowadays, with some destinations even having city-wide Wi-Fi set up. But that Wi-Fi users are connecting their mobile device to may not be the most secure, given cybercriminals can exploit weaknesses in these networks to intercept messages, login credentials, or other personal information. Beyond exploiting weaknesses, some cybercriminals take it a step further and create fake networks with generic names that trick unsuspecting users into connecting their devices. These networks are called “evil-twin” networks. For help in spotting these imposters, there are few tricks the savvy user can deploy to prevent an evil twin network from wreaking havoc on their mobile device:
Fake apps have become a rampant problem for Android and iPhone users alike. This is mainly in part due to malicious apps hiding in plain sight on legitimate sources, such as the Google Play Store and Apple’s App Store. After users download a faulty app, cybercriminals deploy malware that operates in the background of mobile devices which makes it difficult for users to realize anything is wrong. And while users think they’ve just downloaded another run-of-the-mill app, the malware is hard at work obtaining personal data.
In order to keep sensitive information out of the hands of cybercriminals, here are a few things users can look for when they need to determine whether an app is fact or fiction:
With so many types of malware out in the world, it’s hard to keep track of them all. But there is one in particular that mobile device users need to be keenly aware of called grayware. As a coverall term for software or code that sits between normal and malicious, grayware comes in many forms, such as adware, spyware or madware. While adware and spyware can sometimes operate simultaneously on infected computers, madware — or adware on mobile devices — infiltrates smartphones by hiding within rogue apps. Once a mobile device is infected with madware from a malicious app, ads can infiltrate almost every aspect on a user’s phone. Madware isn’t just annoying; it also is a security and privacy risk, as some threats will try to obtain users’ data. To avoid the annoyance, as well as the cybersecurity risks of grayware, users can prepare their devices with these cautionary steps:

How do hackers hack phones? Several ways. Just as there are several ways you can prevent it from happening to you.The thing is that our phones are like little treasure chests. They’re loaded with plenty of personal data, and we use them to shop, bank, and take care of other personal and financial matters—all of which are of high value to identity thieves. However, you can protect yourself and your phone by knowing what to look out for and by taking a few simple steps. Let’s break it down by first taking a look at some of the more common attacks.
Whether hackers sneak it onto your phone by physically accessing your phone or by tricking you into installing it via a phony app, a sketchy website, or a phishing attack, hacking software can create problems for you in a couple of ways:
Some possible signs of hacking software on your phone include:
In all, hacking software can eat up system resources, create conflicts with other apps, and use your data or internet connection to pass along your personal information into the hands of hackers—all of which can lead to some of the symptoms listed above.
These are a classic form of attack. In fact, hackers have leveled them at our computers for years now too. Phishing is where hackers impersonate a company or trusted individual to get access to your accounts or personal info or both. And these attacks take many forms, like emails, texts, instant messages, and so forth, some of which can look really legitimate. Common to them are links to bogus sites that attempt to trick you into handing over that info or that install malware to wreak havoc on your device or likewise steal information. Learning how to spot a phishing attack is one way to keep yourself from falling victim to one.
Professional hackers can use dedicated technologies that search for vulnerable mobile devices with an open Bluetooth connection. Hackers can pull off these attacks when they are within range of your phone, up to 30 feet away, usually in a populated area. When hackers make a Bluetooth connection to your phone, they can possibly access your data and info, yet that data and info must be downloaded while the phone is within range. As you probably gathered, this is a more sophisticated attack given the effort and technology involved.
In August of 2019, the CEO of Twitter had his SIM card hacked by SIM card swapping scam. SIM card swapping occurs when a hacker contacts your phone provider, pretends to be you, and then asks for a replacement SIM card. Once the provider sends the new SIM to the hacker, the old SIM card will be deactivated, and your phone number will be effectively stolen. This means the hacker has taken control of your phone calls, messages, and so forth. This method of hacking requires the seemingly not-so-easy task of impersonating someone else, yet clearly, it happened to the CEO of a major tech company. Protecting your personal info and identity online can help prevent hackers from impersonating you to pull off this and other crimes.
While there are several ways a hacker can get into your phone and steal personal and critical information, here are a few tips to keep that from happening:
The post How Do Hackers Hack Phones and How Can I Prevent It? appeared first on McAfee Blog.
With Microsoft's recent announcement regarding the blocking of macros in documents originating from the internet (email AND web download), attackers have began aggressively exploring other options to achieve user driven access (UDA). There are several considerations to be weighed and balanced when looking for a viable phishing for access method:
These are the major questions, however there are certainly more. Things get more complex as you realize that these factors compound each other; for example, if a client has a web proxy that prohibits the download of executables or DLL's, you may need to stick your payload inside a container (ZIP, ISO, etc). Doing so can present further issues down the road when it comes to detection. More robust defenses require more complex combinations of techniques to defeat.
This article will be written with a fictional target organization in mind; this organization has employed several defensive measures including email filtering rules, blacklisting certain file types from being downloaded, application whitelisting on endpoints, and Microsoft Defender for Endpoint as an EDR solution.
Real organizations may employ none of these, some, or even more defenses which can simplify or complicate the techniques outlined in this research. As always, know your target.
XLL's are DLL's, specifically crafted for Microsoft Excel. To the untrained eye they look a lot like normal excel documents.
XLL's provide a very attractive option for UDA given that they are executed by Microsoft Excel, a very commonly encountered software in client networks; as an additional bonus, because they are executed by Excel, our payload will almost assuredly bypass Application Whitelisting rules because a trusted application (Excel) is executing it. XLL's can be written in C, C++, or C# which provides a great deal more flexibility and power (and sanity) than VBA macros which further makes them a desirable choice.
The downside of course is that there are very few legitimate uses for XLL's, so it SHOULD be a very easy box to check for organizations to block the download of that file extension through both email and web download. Sadly many organizations are years behind the curve and as such XLL's stand to be a viable method of phishing for some time.
There are a series of different events that can be used to execute code within an XLL, the most notable of which is xlAutoOpen. The full list may be seen here:
Upon double clicking an XLL, the user is greeted by this screen:
This single dialog box is all that stands between the user and code execution; with fairly thin social engineering, code execution is all but assured.
Something that must be kept in mind is that XLL's, being executables, are architecture specific. This means that you must know your target; the version of Microsoft Office/Excel that the target organization utilizes will (usually) dictate what architecture you need to build your payload for.
There is a pretty clean break in Office versions that can be used as a rule of thumb:
Office 2016 or earlier: x86
Office 2019 or later: x64
It should be noted that it is possible to install the other architecture for each product, however these are the default architectures installed and in most cases this should be a reliable way to make a decision about which architecture to roll your XLL for. Of course depending on the delivery method and pretexting used as part of the phishing campaign, it is possible to provide both versions and rely on the victim to select the appropriate version for their system.
The XLL payload that was built during this research was based on this project by edparcell. His repository has good instructions on getting started with XLL's in Visual Studio, and I used his code as a starting point to develop a malicious XLL file.
A notable deviation from his repository is that should you wish to create your own XLL project, you will need to download the latest Excel SDK and then follow the instructions on the previously linked repo using this version as opposed to the 2010 version of the SDK mentioned in the README.
Delivery of the payload is a serious consideration in context of UDA. There are two primary methods we will focus on:
Either via attaching a file or including a link to a website where a file may be downloaded, email is a critical part of the UDA process. Over the years many organizations (and email providers) have matured and enforced rules to protect users and organizations from malicious attachments. Mileage will vary, but organizations now have the capability to:
Fuzzing an organization's email rules can be an important part of an engagement, however care must always be taken so as to not tip one's hand that a Red Team operation is ongoing and that information is actively being gathered.
For the purposes of this article, it will be assumed that the target organization has robust email attachment rules that prevent the delivery of an XLL payload. We will pivot and look at web delivery.
Email will still be used in this attack vector, however rather than sending an attachment it will be used to send a link to a website. Web proxy rules and network mitigations controlling allowed file download types can differ from those enforced in regards to email attachments. For the purposes of this article, it is assumed that the organization prevents the download of executable files (MZ headers) from the web. This being the case, it is worth exploring packers/containers.
The premise is that we might be able to stick our executable inside another file type and smuggle it past the organization's policies. A major consideration here is native support for the file type; 7Z files for example cannot be opened by Windows without installing third party software, so they are not a great choice. Formats like ZIP, ISO, and IMG are attractive choices because they are supported natively by Windows, and as an added bonus they add very few extra steps for the victim.
The organization unfortunately blocks ISO's and IMG's from being downloaded from the web; additionally, because they employ Data Loss Prevention (DLP) users are unable to mount external storage devices, which ISO's and IMG's are considered.
Luckily for us, even though the organization prevents the download of MZ-headered files, it does allow the download of zip files containing executables. These zip files are actively scanned for malware, to include prompting the user for the password for password-protected zip files; however because the executable is zipped it is not blocked by the otherwise blanket deny for MZ files.
Zip files were chosen as a container for our XLL payload because:
Conveniently, double clicking a ZIP file on Windows will open that zip file in File Explorer:
Less conveniently, double clicking the XLL file from the zipped location triggers Windows Defender; even using the stock project from edparcell that doesn't contain any kind of malicious code.
Looking at the Windows Defender alert we see it is just a generic "Wacatac" alert:
However there is something odd; the file it identified as malicious was in c:\users\user\Appdata\Local\Temp\Temp1_ZippedXLL.zip, not C:\users\user\Downloads\ZippedXLL\ where we double clicked it. Looking at the Excel instance in ProcessExplorer shows that Excel is actually running the XLL from appdata\local\temp, not from the ZIP file that it came in:
This appears to be a wrinkle associated with ZIP files, not XLL's. Opening a TXT file from within a zip using notepad also results in the TXT file being copied to appdata\local\temp and opened from there. While opening a text file from this location is fine, Defender seems to identify any sort of actual code execution in this location as malicious.
If a user were to extract the XLL from the ZIP file and then run it, it will execute without any issue; however there is no way to guarantee that a user does this, and we really can't roll the dice on popping AV/EDR should they not extract it. Besides, double clicking the ZIP and then double clicking the XLL is far simpler and a victim is far more prone to complete those simple actions than go to the trouble of extracting the ZIP.
This problem caused me to begin considering a different payload type than XLL; I began exploring VSTO's, which are Visual Studio Templates for Office. I highly encourage you to check out that article.
VSTO's ultimately call a DLL which can either be located locally with the .XLSX that initiates everything, or hosted remotely and downloaded by the .XLSX via http/https. The local option provides no real advantages (and in fact several disadvantages in that there are several more files associated with a VSTO attack), and the remote option unfortunately requires a code signing certificate or for the remote location to be a trusted network. Not having a valid code signing cert, VSTO's do not mitigate any of the issues in this scenario that our XLL payload is running into.
We really seem to be backed into a corner here. Running the XLL itself is fine, however the XLL cannot be delivered by itself to the victim either via email attachment or web download due to organization policy. The XLL needs to be packaged inside a container, however due to DLP formats like ISO, IMG, and VHD are not viable. The victim needs to be able to open the container natively without any third party software, which really leaves ZIP as the option; however as discussed, running the XLL from a zipped folder results in it being copied and ran from appdata\local\temp which flags AV.
I spent many hours brain storming and testing things, going down the VSTO rabbit hole, exploring all conceivable options until I finally decided to try something so dumb it just might work.
This time I created a folder, placed the XLL inside it, and then zipped the folder:
Clicking into the folder reveals the XLL file:
Double clicking the XLL shows the Add-In prompt from Excel. Note that the XLL is still copied to appdata\local\temp, however there is an additional layer due to the extra folder that we created:
Clicking enable executes our code without flagging Defender:
Nice! Code execution. Now what?
The pretexting involved in getting a victim to download and execute the XLL will vary wildly based on the organization and delivery method; themes might include employee salary data, calculators for compensation based on skillset, information on a project, an attendee roster for an event, etc. Whatever the lure, our attack will be a lot more effective if we actually provide the victim with what they have been promised. Without follow through, victims may become suspicious and report the document to their security teams which can quickly give the attacker away and curtail access to the target system.
The XLL by itself will just leave a blank Excel window after our code is done executing; it would be much better for us to provide the Excel Spreadsheet that the victim is looking for.
We can embed our XLSX as a byte array inside the XLL; when the XLL executes, it will drop the XLSX to disk beside the XLL after which it will be opened. We will name the XLSX the same as the XLL, the only difference being the extension.
Given that our XLL is written in C, we can bring in some of the capabilities from a previous writeup I did on Payload Capabilities in C, namely Self-Deletion. Combining these two techniques results in the XLL being deleted from disk, and the XLSX of the same name being dropped in it's place. To the undiscerning eye, it will appear that the XLSX was there the entire time.
Unfortunately the location where the XLL is deleted and the XLSX dropped is the appdata\temp\local folder, not the original ZIP; to address this we can create a second ZIP containing the XLSX alone and also read it into a byte array within the XLL. On execution in addition to the aforementioned actions, the XLL could try and locate the original ZIP file in c:\users\victim\Downloads\ and delete it before dropping the second ZIP containing just the XLSX in it's place. This could of course fail if the user saved the original ZIP in a different location or under a different name, however in many/most cases it should drop in the user's downloads folder automatically.
This screenshot shows in the lower pane the temp folder created in appdata\local\temp containing the XLL and the dropped XLSX, while the top pane shows the original File Explorer window from which the XLL was opened. Notice in the lower pane that the XLL has size 0. This is because it deleted itself during execution, however until the top pane is closed the XLL file will not completely disappear from the appdata\local\temp location. Even if the victim were to click the XLL again, it is now inert and does not really exist.
Similarly, as soon as the victim backs out of the opened ZIP in File Explorer (either by closing it or navigating to a different folder), should they click spreadsheet.zip again they will now find that the test folder contains importantdoc.xlsx; so the XLL has been removed and replaced by the harmless XLSX in both locations that it existed on disk.
This GIF demonstrates the download and execution of the XLL on an MDE trial VM. Note that for some reason Excel opens two instances here; on my home computer it only opened one, so not quite sure why that differs.
As always, we will ask "What does MDE see?"
A quick screenshot dump to prove that I did execute this on target and catch a beacon back on TestMachine11:
First off, zero alerts:
What does the timeline/event log capture?
Yikes. Truth be told I have no idea where the keylogging, encrypting, and decrypting credentials alerts are coming from as my code doesn't do any of that. Our actions sure look suspicious when laid out like this, but I will again comment on just how much data is collected by MDE on a single endpoint, let alone hundreds, thousands, or hundreds of thousands that an organization may have hooked into the EDR. So long as we aren't throwing any actual alerts, we are probably ok.
The moment most have probably been waiting for, I am providing a code sample of my developed XLL runner, limited to just those parts discussed here in the Tradecraft section. It will be on the reader to actually get the code into an XLL and implement it in conjunction with the rest of their runner. As always, do no harm, have permission to phish an organization, etc.
I have included the source code for a program that will ingest a file and produce hex which can be copied into the byte arrays defined in the snippet. Use this on the the XLSX you wish to present to the user, as well as the ZIP file containing the folder which contains that same XLSX and store them in their respective byte arrays. Compile this code using:
gcc -o ingestfile ingestfile.c
I had some issues getting my XLL's to compile using MingW on a kali machine so thought I would post the commands here:
x64
x86_64-w64-mingw32-gcc snippet.c 2013_Office_System_Developer_Resources/Excel2013XLLSDK/LIB/x64/XLCALL32.LIB -o importantdoc.xll -s -Os -DUNICODE -shared -I 2013_Office_System_Developer_Resources/Excel2013XLLSDK/INCLUDE/
x86
i686-w64-mingw32-gcc snippet.c 2013_Office_System_Developer_Resources/Excel2013XLLSDK/LIB/XLCALL32.LIB -o HelloWorldXll.xll -s -DUNICODE -Os -shared -I 2013_Office_System_Developer_Resources/Excel2013XLLSDK/INCLUDE/
After you compile you will want to make a new folder and copy the XLL into that folder. Then zip it using:
zip -r <myzipname>.zip <foldername>/
Note that in order for the tradecraft outlined in this post to work, you are going to need to match some variables in the code snippet to what you name the XLL and the zip file.
With the dominance of Office Macro's coming to a close, XLL's present an attractive option for phishing campaigns. With some creativity they can be used in conjunction with other techniques to bypass many layers of defenses implemented by organizations and security teams. Thank you for reading and I hope you learned something useful!

So much of our personal and professional lives are online — from online banking to connecting with friends and family to unwinding after a long day with our favorite movies and shows. The internet is a pretty convenient place to be! Unfortunately, it can also be a convenient place for cybercriminals and identity theft.
One way these scammers may try to take advantage of someone is by trying to convince them to give up their personal information or click on links that download things like malware. They might try to appear as a trustworthy source or someone you personally know. This fake online communication is called “phishing.”
As we’ve all heard before, knowledge is power. By understanding what phishing is, how it works, and the signs to look for, you can help minimize your risk and get back to enjoying the internet the way it was intended. Here’s what you should know.
You’ve probably heard of the term “phishing,” but maybe you don’t know what it means. Here’s a quick overview of how it works.
Phishing is a type of cybercrime where scammers send communications that appear to be from trusted sources like a major corporation — basically, they’re trying to play off people’s trust through what is known as social engineering. They might request sensitive information like passwords, banking information, and credit card numbers. Hackers may then use this information to access your credit cards or bank accounts.
The thing with phishing attacks, though, is that they can come through several platforms, including:
We’ve mentioned that phishers are looking to get sensitive information, but what exactly are they after? The kind of information phishing scams are after might include:
Phishing scams can come in many forms, but understanding the common types of phishing attacks can help you keep identity thieves at bay. Here are some to be aware of:
A phishing email is a fraudulent email made to look like it’s from a legitimate company or person. It may ask you to provide personal information or click on a link that downloads malware. For example, an email allegedly from Bank of America notes that due to suspicious activity, you should log into your bank account to verify your information.
Fortunately, there are ways to spot a phishing cyberattack like this.
While some phishing emails are sent to a broad audience, spear phishing emails target specific individuals or businesses. This allows the scammers to research the recipient and customize the message to make it look more authentic.
Examples of spear phishing emails include:
One of the best defenses against spear phishing is to contact the source of an email to verify the request. Call the colleague who’s asking you to do a wire transfer or log onto your Amazon account to check for messages.
For this highly customized scam, scammers duplicate a legitimate email you might have previously received and add attachments or malicious links to a fake website. The email then claims to be a resend of the original. Clicking a malicious link can give spammers access to your contact list. Your contacts can then receive a fake email that appears to be from you.
While clone phishing emails look authentic, there are ways to spot them. They include:
Through vishing or voice phishing, scammers call you and try to persuade you to provide sensitive data. They might use caller ID spoofing to make the call appear to be from a local business or even your own telephone number. Vishing calls are usually robocalls that leave a voicemail or prompt you to push buttons for an operator. The intent is to steal credit card information or personal and financial information to be used in identity theft.
Fortunately, there are signs that give away these attacks. They include:
If you’d like to avoid vishing calls, there are several things you can do. When you don’t recognize the number, don’t answer the phone. Let the call go to voicemail, then block it if it isn’t legitimate. Use a call-blocking app to filter calls coming to your cellphone. To block calls on a landline, check with your service provider regarding the services offered.
Dealing with a cybercriminal is no time to be polite. If you do answer a vishing call, hang up as soon as you realize it. Don’t answer any questions, even with a yes or no. Your voice could be recorded and used for identity theft. If they ask you to push a button to be removed from a call list, don’t do it. You’ll just receive more calls.
If you receive a voicemail and are unsure if it’s legitimate, call the company directly using the phone number on the company website. Don’t call the number in the voicemail.
If you’ve ever received a text pretending to be from Amazon or FedEx, you’ve experienced smishing. Scammers use smishing (SMS phishing) messages to get people to click on malicious links with their smartphones. Some examples of common fraudulent text messages include:
If you receive a smishing text, don’t respond because it’ll cause you to receive more texts. Instead, delete the text and block the number.
Pop-up phishing occurs when you’re on a website and a fake pop-up ad appears. It encourages you to click a link or call a number to resolve the issue. Some of these reload repeatedly when you try to close them or freeze your browser.
Common pop-up scams include:
If you see a scam pop-up ad, don’t click on the ad or try to click the close button within the ad. Instead, close out of the browser window. If your browser is frozen, use the task manager to close the program on a PC. On a Mac, click the Apple icon and choose Force Quit.
Being online makes us visible to a lot of other people, including scammers. Fortunately, there are things you can do if you become a victim of phishing — allowing you to get back to enjoying the digital world. They include:
You deserve to live online freely. But that might mean taking steps to protect yourself from phishing attempts. Here are some ways you can improve your cybersecurity and keep scammers at bay:
You don’t have to stop enjoying the internet just because of phishing attempts. McAfee’s identity theft protection services, including antivirus software, make it possible to enjoy your digital world while staying safe from scammers and identity thieves.
