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.

As 2022 draws to a close, the Threat Research Team at McAfee Labs takes a look forward—offering their predictions for 2023 and how its threat landscape may take shape.
This year saw the continued evolution of scams, which is unlikely to slow down, as well as greater adoption of Chrome as an operating system. It also saw the introduction of AI tools that are easy and accessible to virtually anyone with a phone or laptop, which will continue to have significant implications, as will the fluctuating popularity of cryptocurrency and the emergence of “Web3.”
Advances such as these have set the stage for 2023, which will continue to reshape our interactions with technology—advances that bad actors will try to exploit, and in turn, us.
Yet as the threat landscape continues to evolve, so do the ways we can protect ourselves. With that, we share McAfee’s threat predictions for 2023, along with insights and advice that can help us enjoy the advances to come with confidence.

Humans have been fascinated by artificial intelligence (AI) for almost as long as we’ve been using computers. And in some cases, even fearful of it. Depictions in pop culture range from HAL, the sentient computer from 2001: A Space Odyssey to Skynet, the self-aware neural network at the center of the Terminator franchise. The reality of current AI technologies is both more complicated and less autonomous than either of these. While AI is rapidly evolving, humans remain at the heart of it, and whether it’s put to beneficial or nefarious use.
Within the last few months, creating AI-generated images, videos, and even voices are no longer strictly left to professionals. Now anyone with a phone or computer can take advantage of the technology using publicly available applications like Open AI’s Dall-E or stability.ai’s Stable Diffusion. Google has even made creating AI-generated videos easier than ever.
What does this mean for the future? It means the next generation of content creation is becoming available to the masses and will only continue to evolve. People both at work and at home will have the ability to create the AI-generated content in minutes. Just as desktop publishing, photo editing, and inexpensive photorealistic home printers created major advances that empowered individuals to create content that previously required a professional designer, these technologies will enable sophisticated outputs with minimal expertise or effort.
Advances in desktop publishing and consumer printing also provided benefits to criminals, enabling better counterfeiting and more realistic manipulation of images. Similarly, these emerging next-generation content tools will also be used by a range of bad actors. From cybercriminals to those seeking to falsely influence public opinion, these tools will empower scammers and propagandists to take their tradecraft to the next level with more realistic results and significantly improved efficiency.
This is especially likely to ramp up in 2023 as the U.S. begins the 2024 presidential election cycle in earnest. Globally, the political environment is polarized. The confluence of the emergence of accessible next-generation generative AI tools and what is sure to be a highly contested 2024 election season is a perfect storm for creating and distributing disinformation for political and monetary gain.
We’ll all need to be more mindful of the content we consume and the sources that it originates from. Fact-checking images, videos, and news content, something that’s already on the rise, will continue to be a necessary and valuable part of media consumption.

Cryptocurrency scams
In 2022 we saw several online scams making use of existing content to make crypto scams more believable. One such example was the double your money cryptocurrency scam that used an old Elon Musk video as a lure. We expect such scams to evolve in 2023 and make use of deep fake videos, as well as audio, to trick victims into parting ways with their hard-earned money.
The financial outlook of 2023 remains uncertain for many people. During these times, people often look for ways to make some extra money and this can lead them vulnerable to social media messages and online ads that offer huge financial gains for little investment.
According to the IC3 2021 report, the losses for financial scams increased from $336,469,000 in 2020 to $1,455,943,193 in 2021, this shows that this type of scam is growing by an enormous amount, and we expect this to continue.
Unfortunately, scammers will often target the most vulnerable people. Fake loan scams are one such scam where the scammers know that the victims are desperate for the loan and therefore are less likely to react to warning signs such as asking for an upfront fee. McAfee predicts that there will be a large increase in these types of scams in 2023. When looking for a loan, always use a trusted provider and be careful of clicking on online ads.
Metaverses such as Facebook’s Horizon enable their users to explore an online world that was previously unimaginable. When these platforms are in the early stages, malicious actors will usually attempt to exploit the lack of understanding of how they work and use this to scam people. We have observed phishing campaigns targeting users of these platforms in 2022 and we expect this to increase dramatically in 2023 as more and more users sign up for the platforms.

More than 25 years ago, Windows 95 became the platform of choice not just for millions of users around the globe, but for malware authors targeting those users. Over the years, Windows has evolved, as has the threat landscape. Today, Windows 10 and 11 make up the majority of the desktop PC market, but thanks to the rise of the mobile Internet, device diversity has greatly evolved since the advent of Windows 95.
Over five years ago, Android overtook Windows as the world’s most popular OS and with this shift bad actors have been pursing alternative methods of attack. The ultimate vectors are those which impact users across a spectrum of devices. Email and web-based scams (some of which are outlined in the blog above) are as prolific as ever as these technologies are ubiquitous across desktop and mobile devices.
Meanwhile, other technologies span across desktop and mobile experiences as well. For Google, such cross-platform capabilities are highlighted by increased adoption of ChromeOS and a few underlying technologies. This includes 270 million active Android users and a 270% increase in Progressive Web Application (PWA) installations [https://chromeos.dev]. ChromeOS’ ability to run Android applications, combined with its wide-spread adoption, provides the climate for increased attention by those with ill intentions.
Similarly, adoption of PWAs provide bad actors with additional incentive to deliver deceptive and imposter attacks through this multi-OS channel, including ChromeOS, iOS, MacOS, and Windows.
Finally, on the heels of COVID restrictions that impacted schools in various countries, Google reported 50 million students and educators worldwide [https://chromeos.dev] using ChromeOS. Many users will be unaware of malicious Chrome extensions lurking in the Chrome Web Store.
All of this means that the stage is set for a marked increase in threats impacting Chromebook in the year to come. In 2023, we can expect to see Chromebook users among millions of unsuspecting victims that download and run malicious content, whether from malicious Android Apps, Progressive Web Apps, or Chrome Web Store extensions, users should be leery of popups and push notifications urging them to install untrusted apps.

Editor’s Note: Web3? FOMO? If you’re already lost, you’re not alone. Web3 is a term some use to encompass decentralized internet services, technologies like Bitcoin and Non-Fungible Tokens (digital art that collectors can purchase with cryptocurrency). Still confused? A lot of people are. This New York Times article is a good primer on what is currently considered Web3.
As for FOMO, that’s just an acronym meaning the “Fear of Missing Out.” That nagging feeling, most often felt by extroverts, that others are out there having more fun than them and that they’re missing the party.
Whether you invest in cryptocurrency or just see the headlines on Twitter, no doubt you’ve seen that the price of cryptocurrency has sharply declined during 2022. These fluctuations are becoming more normal as crypto becomes even more mainstream. It’s very likely that the value of crypto will rise again.
When the last upturn in valuation happened near the start of the pandemic, the hype about crypto also skyrocketed. Suddenly Bitcoin and other cryptocurrencies were everywhere. Out of that, rose the concept of Web3, with more companies investing in new applications over blockchain (the technology that is the backbone of cryptocurrency).
McAfee predicts that the popularity of cryptocurrency will rise again, and consumers will hear much more about Web3 concepts like decentralized finance (DeFi), decentralized autonomous organizations (DAOs), self-sovereign identity (SSI) and more.
Some amateur investors, remembering the rapid rise of the value of Bitcoin earlier this decade, won’t want to miss out on what they think will be a great opportunity to get rich quick. It’s this group that bad actors will seek to exploit, offering up links or applications that play on these users’ crypto/Web3 FOMO.
As crypto bounces back and initial awareness of decentralization grows in the general population, consumers will begin to explore these Web3 offerings without fully understanding what they mean or what dangers they should be aware of, leaving them open to scams as they invest time and money into crypto or creating their own NFT content. These scams could entice users to click on a link or download an app that appears to legitimately interact with some blockchains, but in actuality:
Additionally, when consumers DO hold crypto, NFT, digital land, or other blockchain financial assets they are going to be targeted for more sophisticated threats that can drain their funds: smart contracts, exchanges, digital wallets, and synchronization services can all be associated with hidden authorizations that allow a third party (potentially a bad actor) to take control of the assets. It’s important that users read the terms and conditions of any app they download, especially those that will be accessing ANY type of financial institution or currency, whether traditional or crypto.
Social engineering will also continue to be a top entry point for cybercriminals. The complexity of the attacks will evolve as the technology does, which will require more preparation and understanding of how Web3 applications and tools work in order to safely interact with them.
What has emerged from the world of Web3 thus far, while exciting, has also expanded attack surfaces and vectors, which we expect to see grow throughout 2023 as Web3 evolves.

Two years ago, we asked the question: What actually works in cybersecurity?
Not what everyone’s doing—because there are plenty of cybersecurity reports out there that answer that question—but which data-backed practices lead to the outcomes we want to implement in cybersecurity strategies?
The result was the first Security Outcomes Report, in which we analyzed 25 cybersecurity practices against 11 desired outcomes. And thanks to a large international respondent group, together with the mighty data science powers of the Cyentia Institute, we got some good data that raised as many questions as it answered. Sure, we found some strong correlations between practices and outcomes, but why did they correlate?
Last year, our second report focused in on the top five most highly correlated practices and tried to reveal more detail that would give us some guidance on implementation. We found that certain types of technology infrastructure correlated more with those successful practices, and therefore with the outcomes we’re seeking. Is architecture really destiny when it comes to good security outcomes? It does appear to be the case, but we had more research ahead of us to be more confident in a statement that sweeping.
All the while, we’ve been listening to readers considering what they’d like to glean from this research. One big question was, “How do we turn these practices into management objectives?” In other words, now that we have some data on practices we should be implementing, how do we set measurable goals to do so? I’ve led workshops in the UK and in Colombia to help CISOs set their own objectives based on their risk management priorities, and we’ve worked to identify longer-term targets that require close alignment with business leaders.
Another question that took a front-row seat in our presentations and just wouldn’t leave: the topic of cyber resilience, or security resilience. It’s almost reached the status of a buzzword in the security industry, but you can understand why it’s ubiquitous.
“Among the upheaval of the pandemic, political unrest, economic and climate turbulence, and war, everyone is struggling to find a new ‘business as usual’ state that includes being able to adapt better to the shaky ground beneath them.”
But what exactly is security resilience, anyway? What does it mean to security practitioners and executives around the world? And what are the associated cybersecurity outcomes that we can identify and correlate? We know it doesn’t simply mean preventing bad things from happening; that ship has sailed (and sunk). We also know that security resilience doesn’t always mean full recovery from an event or condition that has knocked you down. Rather, it means continuing to operate during an adverse situation, either at full or partial capacity, and mitigating the effects on stakeholders. Ideally speaking, security resilience also means learning from the experience and emerging stronger.
Security resilience is the focus of the third volume of our Security Outcomes Report: Achieving Security Resilience. It tells us how 4,700 practitioners across 26 countries are prioritizing security resilience: what it means to them, what they’re doing successfully to achieve it, and what they’re struggling with. Once again, the data gives us interesting ideas to ponder.
A stronger security culture boosts resilience by as much as 46%. By “culture,” we don’t mean annual compliance-driven awareness training. Cybersecurity awareness is what you know; security culture is what you do. When organizations score better at being able to explain just what it is that they need to do in security and why, they make better decisions in line with their security values, and that leads to better overall security resilience.
It doesn’t matter how many people you have; it matters whether you have any of them available in reserve to respond to events. Organizations with a flexible pool of talent internally (or on standby externally) show anywhere from 11% to 15% improvement in resilience. Which makes sense, as a fully leveraged team will be strained if they have to work even harder to take on an incident.
Because so many organizations around the world are looking to the NIST Cybersecurity Framework as a guidepost for cybersecurity practices, we also analyzed which NIST CSF capabilities correlated most strongly with our list of resilience outcomes. For example, our survey respondents that do a great job tracking key systems and data are almost 11% more likely to excel at containing the spread and scope of security incidents. From one angle, this seems like an obvious result, hardly worth mentioning. On the other hand, it’s worth presenting to your management some data that shows that investing in asset inventory solutions really does have long-range effects on your ability to stop an intrusion.
And there’s much more. The report identifies—and then explores—seven success factors that, if achieved, boost our measure of overall security resilience from the bottom 10th percentile to the top 10th percentile. These include establishing a security culture and properly resourcing response teams, among others.
I hope this introductory blog—the first in a series exploring this latest report—whets your appetite to read the report itself. And remember, we are always aiming to reveal the next undiscovered insight that leads to better security outcomes. Please share your feedback and research requests with us in the comments below, or talk to us at the next security conference.
For more insights like what you’ve seen in today’s blog take a look at the Security Outcomes Report, Volume 3: Achieving Security Resilience.
