This week on Lock and Code, we discuss the top security headlines generated right here on Labs and around the Internet. In addition, we talk to Pieter Arntz, malware intelligence researcher for Malwarebytes, about Google Chrome extensions.

These sometimes helpful online tools that work directly with the Google Chrome browser can pull off a variety of tricks—checking your grammar, scouring the web for coupon codes, and providing a dark mode for easier nighttime browsing.

But the Google Chrome extension landscape is enormous, and, for countless users trying to navigate it, they can run into trouble.

Tune in to hear about the the history of web browser extensions, and how to spot and protect against malicious Google Chrome extensions on the latest episode of Lock and Code, with host David Ruiz.

You can also find us on the Apple iTunes store, Google Play Music, and Spotify, plus whatever preferred podcast platform you use.

We cover our own research on:

• Malvertising campaigns, and why they have come back in full swing.
• The global shift in dark web purchasing due to the coronavirus pandemic.
• What possible cyber threats during the election season that every informed voter should know, expect, and act upon.

Singapore held its most recent general election on July 10 2020, and although they used the electoral system called first-past-the-post (FPTP), a scheme favored by the US, UK, and most English-speaking countries, the road leading to Election Day was not without challenges and obstacles.

While all voters used paper ballots (thus removing the exposure to risk that comes with using electronic voting machines), phishing attempts, disinformation, threats of hacking political parties, and other election cyberthreats were nonetheless ever-present.

In light of the ongoing COVID-19 pandemic and the election technologies we know could be abused in the wrong hands, we look at these and other potential election cyberthreats—past, present, and (if pervasive enough) future—that the security world has observed for quite a while now, so that informed voters can remain informed and hopefully continue exercising your right to vote whenever and wherever that may be.

Ask, and ye shall know

Avid readers of this blog would know that we stress upon the importance of asking the right questions when it comes to deciding on what to do online, what to buy (and where), and which technologies to use. In this case, we’d like to know which election threats that we’d be facing and the ways we can protect against them or otherwise address them.

And in attempting to answer these, we first need to know what or who could be targeted during an election. This way, we’d also know what to protect and how. So, we ask—

What are election assets?

To identify the threats we can likely see/face/observe during election period, it is important to identify an election’s critical assets, which will in turn aid us in recognizing and categorizing threats to these assets and to the election as a whole.

Election assets are:

Infrastructure. This pertains to places where polling is held, including storage facilities for elections and locations where election systems are physically set up. If we want to be granular, the US Department of Homeland Security (DHS) listed some of these as: voter registration databases and their associated IT systems, election management systems (for counting, auditing, displaying election results, etc.), and voting systems.

Materials. Pretty self-explanatory. These pertain to the objects used during the election process. For example, paper ballots or voter registration cards, pens, and indelible inks.

As of this writing, there have been no real or theorized election cyberthreats lodged against such materials. However, this doesn’t mean that no one has attempted to circumvent their use.

Take, for example, the use of the electoral ink. Its indelibility is a means to prevent constituents from casting more than one vote. With the ongoing pandemic, however, hand sanitizing before and after casting votes could impact the product’s effectiveness. Not to mention that there have been cases in the past where the ink used washed off easily and completely.

People and information. Although they are two completely different entities, we cannot really separate them. The people are the political candidates, their staff, and the parties they represent; the third-party organizations that are directly or indirectly involved in the elections; electoral officials and staff; and, of course, the voters. Under third parties, we can include software and hardware manufacturers. Information, of course, refers to all of the content these people share to the public, amongst each other, and within election systems.

Technology. Voting machines aren’t the only technology that countries use for and during an election. Political candidates have freely made use of printers, mobile phones, and the Internet to reach out and communicate with their supporters. Voting technology also includes systems that are used to efficiently manage the elections. Examples of systems are information management systems, election management systems, and yes, the machine’s operating system itself.

With these in mind, we can start identifying potential threats to these assets. Note that such threats can happen before, during, or even after elections.

Why would cybercriminals do this?

Oftentimes, it is easy to pin down intent based on the kind of threat being carried out. A phishing email, for example, gives a clear indication that whoever is behind the campaign is aiming to gather something from their target—be it sensitive information or money.

In many cases, the phishing email carries with it a malware payload, or a link to its download location. The malware, once executed, then seeks and siphons out information back to its command center. But things don’t end here.

The malware could reside and remain undetected, allowing attackers to gain a foothold onto the target’s network. Sensitive data, credentials, and other information they may have gleaned can be used for their own benefit—from selling to the highest bidder, leaking to disrupt normal operations or call into question a victim’s reputation, and—if some of the files seem personal enough—used to blackmail the victim to extort money.

When it comes to elections, one would likely assume that nation-state actors would interfere to tip the political scales in their favor. Other actors would insert physical disruptions to the otherwise normal election process, either to cover up their true intent—which is usually something more sinister than causing trouble—or “just because.”

There is, however, a solid belief among cybersecurity professionals that the main motivation behind election-fueled attacks is to sow distrust among voters against either their government, the electoral staff and their processes, or the technologies used in conducting the elections. It’s also possible that their aim is all of the above.

How do threat actors disrupt or interfere in elections?

Now that we have identified what threat actors would likely target and why they would target them, we move to answering how threat actors would likely attack these targets. Here’s a comprehensive list of (potential) adversarial activities that has been observed (if not theorized) so far:

Discourse manipulation

We already mentioned earlier that election threats can happen months before election day arrives. Suffice to say that while politicians and election administrators are busy planning and preparing for election day, expect that threat actors are doing the same. One of the more subtle (yet still nefarious) ways of interfering with elections in the run-up to election day is to manipulate the discourse to favor one candidate over another, or simply to cast doubt on the entire election process.

When one manipulates the discourse, one asserts “The Good Me” while also highlighting “The Bad Them.” Unfortunately, we’re all too familiar now with the ways in which cybercriminals (and politicians alike) do this through disinformation, fake news, and computational propaganda.

Disinformation, fake news, and computational propaganda

Several forms of disinformation from all sides of the political spectrum have been around almost as long as politics itself, and certainly pre-date the Internet. Word of mouth and traditional media have helped amplify such campaigns.

With the Internet, and now especially social media, it is easier than ever to, say, cook up stories about what a certain politician purportedly said regarding a sensitive matter that would anger a certain group of people. This can even be accomplished in real time. According to The Global Disinformation Order [PDF], a paper from the Oxford Internet Institute, online disinformation campaigns have been on the uptick since 2017.

There are those who have no real affiliation with government and politics and merely want to earn easy money by targeting certain partisan groups. However, the cybersecurity industry has seen its share of serious organized criminals—often backed by their respective governments—that bank on disinformation campaigns and fake news to accomplish political subterfuge.

There are a number of reasons why governments and political parties spread disinformation, and the classic reasons are to:

1. Discredit their opponents
2. Bury views that oppose theirs
3. Erode trust in the election/election systems
4. Erode trust in democracy or other forms of government

It’s interesting to note that when it comes to conducting deliberate disinformation campaigns, our gut reaction is to point the finger at foreign nationals. There’s certainly precedent. For one, Russia has a known history of spinning phony political stories since the 1920’s.

But nowadays, Russia isn’t the only country engaged in such campaigns—or what others have started calling computational propaganda, which the Oxford Internet Institute defines as “the use of algorithms, automation, and big data to shape public life.” Iran is expanding its online disinformation operations, as are at least 70 more countries. Among these, China has dethroned Russia to become the new king of disinformation.

And then, there is social media manipulation, wherein engineered content is deployed using social networking platforms, and the proliferation of computational propaganda techniques themselves. Threat actors both domestic and foreign have been copying and honing Russia’s disinformation methods from the previous election to influence the outcome of this year’s US general elections.

The Oxford study also asserted that although we have countless social platforms currently in existence, Facebook remains the platform of choice to spread disinformation and fake news.

While governments and groups continue to either point fingers or deny allegations, let’s not forget that the recipients of such material can also amplify disinformation to their network, whether that’s their intention or not. Some may judge the veracity of the material as legitimate. Others may question it but circulate nonetheless to kick off discourse. Either way, both efforts serve to circulate baseless claims and call into question what is the truth.

Hacking

In one of our blogs about election systems in the vital Infrastructure series, we touched on how vulnerable elections could be, highlighting that although voting machines have been hacked successfully on many occasions, doing so at a large scale can actually prove more challenging than what was initially thought. To further complicate matters for potential hackers, not all states use the same voting machine make, model, and supplier. But that doesn’t mean elections are safe from hacking.

Websites can also be hacked, too. Remember that news about the website of the Florida Secretary of State being successfully infiltrated via an SLQ injection done by an 11-year old? Okay, granted, the website was actually a replica of the real thing, but one can’t but help think how potentially vulnerable these supposed critical websites are, especially when being accessed and interacted to by various people—including those with ill intent.

In the last quarter of 2019, McAfee found that swing state election websites aren’t secure from cyberattacks. For starters, the connections of these websites are problematic, as they don’t use HTTPS by default, making them far, far easier to infiltrate. Cybercriminals could make small but significant changes, like altering the websites’ content, that could cause confusion about the dates, locations, and times to vote or otherwise disrupt the election process.

Perhaps, on an even more dangerous note, hackers could do as little as claim to have compromised the site to sew seeds of doubt, casting a shadow over the efficacy of the democratic voting system and eroding the integrity of election results in that state.

Hacking is one of the many attacks on infrastructure that a state or country may encounter during a sensitive time like general elections. The act of infiltrating systems and infrastructures is also usually just the first step of a much larger campaign aimed at destabilizing government or other organizations.

For example, once an election or government site has been hacked, cybercriminals could use information and credentials to kick off a social engineering campaign. This could branch off to cyber espionage (which usually involves using malware), data theft, distributed denial-of-service (DDoS) attacks, and extortion. Come election season, attack campaigns would widen to include the possible interruption of ballots for their modification, deletion, or blocking (the act of blocking ballots from arriving to their supposed destination by threat actors).

Cyber espionage

Foreign spying has always been a challenge for governments, and it doesn’t just happen during the election season. Through the years, cybersecurity experts have investigated nation-state actors who had been involved in election-fueled espionage, particularly advanced persistent threat groups such as APT28, otherwise known as Fancy Bear; the Sandworm team; and APT40, otherwise known as Leviathan.

So far, persistent threat actors have infiltrated diverse targets during elections, from those on staff for a particular candidate or campaign to those responsible for administering ballots or distributing election materials. They are targeted for the sensitive information they have access to, but also for cybercriminals to familiarize themselves with the network’s infrastructure, so they can identity the locations housing critical information that they may use to their advantage.

Phishing

Data theft is a known and given problem during the elections since there is a huge exchange of information going on within distinct groups: among constituents and the registration databases; chat, email, or phone conversations between or among political staff and candidates; and credential information of electoral staff and administrators among others. And one way of stealing such data is via phishing.

In 2017, then-presidential candidate for France Emmanuel Macron confirmed that his staff and party, “En Marche!” or “Onwards!,” were targeted by several advanced phishing campaigns. However, no campaign data was stolen. And this is just one of the many “hundreds if not thousands” of attacks they received from locations inside Russia at that time.

Feike Hacquebord, a researcher from Trend Micro, confirmed these phishing campaigns with some emails containing a malware payload. He also noted that these attacks had telltale signs that connected them previous attacks targeting the campaigns of Hilary Clinton and Angela Merkel in 2016.

Perhaps the most notable political phishing story we can mention here is how President Macron’s campaign was able to turn the tide against the threat actors who were after their data. Led by Mounir Mahjoubi, the campaign’s digital director, they outplayed their attackers using a method called cyber-blurring or digital blurring.

This is a known diversionary tactic in the banking industry, and the Macron campaign used it to slow down and confuse hackers. They did this by deliberately creating fake documents—with some containing outright ridiculous information—accounts, and credentials and mixing them with real but otherwise uninteresting data. As a result, the attackers’ time was wasted, and the burden of proof to justify why they stole or leaked useless information was successfully shifted to the attackers.

Ransomware

Ransomware is seen as one of the big threats during the election season. Some might believe that by using ransomware, threat actors’ primary motivation must be profit in the form of digital coins. In fact, security researchers have reason to believe that, just as with other attack methods and threats used during elections, threat actors are more motivated to undermine the confidence of the results, either at the local level or state level.

“If a ransomware hits an election system, you can pay the ransom or pay a consultancy service. You can restore the data, but you still have the damage done. You cannot undo that damage,” said Lee Imrey, Cybersecurity Advisor for Slunk, in a candid webinar on election threats, “Because, even if you restore all the votes, you’ve lost confidence that the votes you’re restoring are valid votes.”

Possible scenarios also include poll workers not being able to access voter information databases due to them being locked up, which could also happen with websites that post unofficial results on and after Election Day. Some files impacted by ransomware may not being able to reverse their encryption—remember that a notable majority of files affected by a ransomware attack are not typically 100 percent recovered. Finally, a ransomware attack could result in the possible deletion of voter databases and other sensitive data.

It is known that, like some organizations in the private sector, several local governments are ill-equipped to protect themselves from ransomware attacks. Not only do they lack the manpower, they also lack the in-house expertise needed to at least guide them on what to do before, during, and after such a devastating attack.

SIM swapping/SIM swap attack/SIM intercept attack

SIM swapping is a form of identity theft, and it isn’t a new attack. But because of that successful takeover of Jack Dorsey’s own Twitter account, SIM swapping is a thing again.

This is considered an electoral threat because of its high potential to take over high profile accounts belonging to individuals involved in the election proceedings or the politicians themselves with simple social engineering tactics.

Although we have yet to see SIM swap attacks against individuals who are related to the 2020 US General Elections, there is the case of Euridice Pamela Sanchez, an Associated Students Incorporated (ASI) President and CEO candidate for California State University/East bay (VSUEB), being SIM swapped days before ASI elections in March of this year. The still-unknown actor was able to delete all her 3000+ Instagram connections. Since all candidate campaigning is done via social media due to the ongoing pandemic, Sanchez couldn’t reach her supporters to continue her campaign. The attacker also compromised her family’s AT&T account and attempted to access her personal email.

We can only imagine the scale of damage this could cause if political candidates or poll officials—even those in lower positions who may not directly report to them—would become victims of SIM swapping at this crucial time.

DDoS

DDoS can, no doubt, hinder an election process at any point. Take, for example, the cyber attack that affected the UK’s Labor Party’s websites during the 2019 general elections. Not only was the party hit once but twice over. The first attack failed, as confirmed by a National Cyber Security Centre (NCSC) spokesperson with the BBC.

A DDoS attack against websites also disrupted the voting procedures in South Korea in 2011. It was notable that a botnet attack from 200 devices happened in the morning, the time when the younger population of voters would be able to vote before they head for work. Investigators proclaimed that the threat actors were aiming for a low turnout of voters during this time, which in turn would have benefited the conservative party in South Korea.

Such attacks against this part of the election infrastructure could hinder candidates and their staff from accessing data they can use to plan on what campaigns to run in what areas and who they would be targeting to attempt to change their minds.

Deepfakes (and its other forms)

Deepfakes have come under the watchful eye of not just technology and cybersecurity experts but law enforcement as well. And why not? In the wrong hands—from nation-states with agendas tipping to their favor to naughty miscreants who just want to disrupt—it could turn the tides of any election cycle.

Many see deepfakes as another way to make disinformation campaigns more impactful and believable. But perhaps the good thing here is that, at this point in time, people are already familiar with this technology and are actually expecting a form of a politically motivated deepfake to emerge before Election Day, especially at the last minute.

But what really worries Kathryn Harrison, founder and CEO of the DeepTrust Alliance, an alliance devoted to fighting deepfakes and misinformation in general, is the emergence of something that is not a deepfake—a video, for example—of which its veracity cannot be verified. A candidate caught doing or saying something questionable could easily cry “Deepfake!” even if a video is truly legit. Researcher in deepfake circles call this conundrum Liar’s Dividend.

Other foreseen worries include an authority figure reading out wrong elections results, some fake disruptions at certain polling stations, or miseducating constituents on how they can stay safe during Election Day.

How can we protect ourselves from these threats?

For voters, it’s overwhelming to look at this lengthening list of election cyberthreats they might get affected by and feel they have so little time to prepare for to counter or protect themselves from. Fret not—most challenges on this list can only be addressed by governments in the state, local, and national level.

However, there are two things that voters must start doing (if they haven’t already):

Stay informed. Keeping apprised with the current news, especially those that touch on election cycles that are about to happen in your country or state, is one way of staying informed. And while it’s important to know what’s going on, it is equal if not more important to know credible sources of news you can refer to. Disinformation could be anywhere, and we must become smarter. With the elections drawing near, expect such campaigns to pop up in social media and other platforms.

Vote. Whether you feel like going to the polling station—wearing proper protection and following the recommended guidelines, of course—or you prefer to cast your vote via mail, please vote. The more people exercise their democratic right, the less likely electoral fraud can influence the overall outcome of the elections. It’s a numbers game, and we better make sure that the numbers weigh heavy on the side of an honest election cycle.

Good luck and stay safe!

Last year, credentials for PayPal, Facebook, and Airbnb were among the top goods on high demand in the dark web, aka the Internet’s underground market. But due to the COVID-19 outbreak, with most of the worldwide population sheltering, working, and studying indoors, many facets of life have made a full 180-degree turn—including the criminal world.

Almost everything we do is not how we used to do it before, and this is true for public and private individuals, organizations, and governments. And it’s certainly true within the dark web.

According to a recent report by Top10VPN.com, the most valuable data currently being peddled within the dark web are from services that bring about a little ease, relaxation, entertainment, and, admittedly, a little sanity for people sheltering in place.

Here are the findings

It’s no surprise to see a population on lockdown spending more time online than they normally would. And with nothing more important to do than keeping the house tidy, many have been busy binging on TV shows and movies, getting groceries delivered, and investing in mental health or learning something new. Because of this shift, data on these accounts fetches a high price tag on the dark web.

Data related to 72 percent of entries in the above table are noted as “New Item,” which means that they were never traded last year, and yet, they command the highest price tags in the underground market today. This not only gives us an idea of how profound the shift is in the dark web, but also solidifies what we already know: cybercriminals follow the money. And if these sources happen to be low hanging fruits, even better.

Other data types continue to be on high demand during the pandemic. Below is a shortened list of items for sale on the dark web and how much they are worth on average.

More data on the dark web

• Whether the world is in the middle of a pandemic or not, details related to plastic cards, such as debit and credit cards, and banking credentials remain sought after commodities. It is, after all, practically effortless to pull off a heist when you use someone’s stolen credentials to open their account and empty it.
• Underground vendors were also seen selling a fraud bundle, which comprises of hacked debit card data, cryptocurrency accounts, and SIM cards. This allows criminal buyers to SIM jack accounts and syphon money to crypto accounts. Such a bundle is sold for the maximum price of $4,600.
• Fraudsters kept their eyes on SMBs and consumers as they continue to sell details for Cash App (at $47) and Venmo ($14).
• The price of hacked Verizon accounts ($102.50) is noted to have increased ten-fold as they are now being bundled to include customers’ personally identifiable information (PII), such as social security numbers (SSNs) and dates of birth. Not only can buyers use these accounts for personal use, they can use real-world data about someone to pose as them or create new, synthetic identities.
• The lack of air travel during the pandemic had forced some people to settle for the next best thing to a vacation: a staycation. And Airbnb offers the perfect service for this. Airbnb accounts are now more prized than ever. Now valuing $13.50, these accounts can be used to create fake listings or as part of a bigger phishing campaign.
• Hacked accounts from health and wellness services like Peloton, Headspace, and Fitbit (all sold for $7) are used for identity theft and potential house burglary using GPS location data.
• It’s interesting to note that Facebook continues to be the social media platform of choice for cybercriminals. With hacked accounts now valued at $7.79, the platform is still a potent avenue to find and reach targets for various social engineering campaigns. It’s likely that its value will increase as election day draws near.
• Scammers love entertainment services as much as we do, so it’s no surprise for them to start asking for stolen accounts for Netflix (sold at $6), Disney+ (sold at $7), YouTube Premium (sold at $7.50), and Spotify (sold at $3.50).
• Hacked student emails (sold at $6) are hot, presumably because of the “.edu” domain that goes with it. For a targeted campaign, this would be more useful as it brings legitimacy to the content of the email and the purported sender.
• Perhaps what the security community should keep an eye out for are accounts related to new content platforms, OnlyFans (sold at $16) and MasterClass (sold at $6). It is still unclear why such accounts are in high demand and how they are used to commit crime.

Some points to ponder

Because there is an abundance of new hacked data being peddled in the underground, one might wonder if this is just because of the pandemic, and that such goods would eventually decrease their value—if not kill the market entirely—once a vaccine is found and life goes back to normal. So, we asked Simon Migliano, Head of Research at Top10VPN.com, and he thought that these accounts will continue to sell.

“The reality is that even if people do stop using services such as Instacart or Peloton as they return to picking up their own groceries or going to the gym, it’s unlikely that they will completely delete their accounts when they cancel their subscriptions,” Migliano said, “This abandonment of unused accounts is an aspect of consumer behavior online commonly exploited by cybercriminals to harvest personal data.”

Migliano also asserted that, if not for the pandemic, these peddled goods would have looked quite different. “Had there not been a pandemic, we would have seen many more travel brand accounts credentials for sale, such as for Uber, Expedia and JetBlue. I would also have expected to see a much greater range of online retail beyond Amazon and big box stores like Walmart.”

Time to wise up on cybersecurity best practices

If you, dear reader, are worried about the data found for sale on the dark web or have accounts on any of these sites and services, it’s a good idea to start taking computer security hygiene seriously. If you’re not sure where to begin, here are some quick and helpful tips:

• Use a password manager. They help hold multiple strings of account passwords that our memories cannot, plus encrypt and sometimes periodically change those passwords to keep them away from prying criminal eyes. Another option is to use a hardware authentication device or a hardware security key, and there are a lot of them in the market for you to check out.
• Always have two-factor authentication (2FA) enabled on all your accounts.
• Spring clean online accounts you don’t use or rarely use. Much like what we do with the apps we install on our phones but never got around to using them until they were forgotten, we should also make it a point to check for possible accounts you own and delete them if you haven’t used them for months or years. It’s a bit of a chore, yes, but like forgotten apps, these accounts could be unlocked doors just waiting for cybercriminals to open.
• Keep an eye out for notifications of account breaches. Some of the services we use are responsible enough to let us know when something has gone wrong. But there are also services that neglect this important step. If you’re unsure whether your account for a certain service has been compromised, try visiting and sending a query to Have I Been Pwned.
• Update software on all devices you use.
• Install software that can protect you from malware and harmful sites.

Now is as good a time as any always to start making a habit of practicing effective security methods, whether you are still sheltering at home or have ventured out into the world. Equip yourself with knowledge and common sense online behaviors, and you can protect against threats from the dark web or anywhere else.

Stay safe!

The post Report: Pandemic caused significant shift in buyer appetite in the dark web appeared first on Malwarebytes Labs.

Malvertising campaigns leading to exploit kits are nowhere near as common these days. Indeed, a number of threat actors have moved on to other delivery methods instead of relying on drive-by downloads.

However, occasionally we see spikes in activity that are noticeable enough that they highlight a successful run. In late August, we started seeing a Fallout exploit kit campaign distributing the Raccoon Stealer via high-traffic adult sites. Shortly after we reported it to the ad network, the same threat actor came back again using the RIG exploit kit instead.

Then we saw possibly the largest campaign to date on top site xhamster[.]com from a malvertiser we have tracked for well over a year. This threat actor has managed to abuse practically all adult ad networks but this may be the first time they hit a top publisher.

Malvertising on popular ad network

The first malicious advertiser we observed was able to bid for ads on a number of adult sites by targeting users running Internet Explorer without any particular geolocation restriction, although the majority of victims were in the US.

In this campaign, the crooks abused the popular ad network ExoClick by using different redirection pages. However, each time we were able to notify the ad network and get them shut down quickly.

The first domain they used was inteca-deco[.]com, which was setup as a web design agency but visibly a decoy page to the trained eye.

Simple server-side cloaking performs the redirect to a Fallout exploit kit landing page witch attempts to exploit CVE-2019-0752 (Internet Explorer) and CVE-2018-15982 (Flash Player) before dropping the Raccoon Stealer.

About 10 days later, another domain, websolvent[.]me, became active but used a different redirection technique, a 302 redirect, also known as 302 cushioning. This time we see the RIG exploit kit which also delivers Raccoon Stealer.

Beyond a common payload, those two domains are also related. A RiskIQ crawl confirms a relationship between these 2 domains where the parent host was caught doing a meta refresh redirect to the child:

Malvertising on top adult site gets maximum reach

The second malvertiser (‘malsmoke’) is one that we have tracked diligently over the past several months and whose end payload is often the Smoke Loader malware. It is by far the most daring and successful one in that it goes after larger publishers and a variety of ad networks. However, up until now we had only seen them on publishers from the adult industry that are still relatively small in scale.

In this instance, the threat actor was able to abuse the Traffic Stars ad network and place their malicious ad on xhamster[.]com, a site with just over 1.06 billion monthly visits according to SimilarWeb.com.

The gates used by this group also use a decoy site and over time they have registered domains mocking ad networks and cloud providers.

The redirection mechanism is more sophisticated than those used in other malvertising campaigns. There is some client-side fingerprinting and connectivity checks to avoid VPNs and proxies, only targeting legitimate IP addresses.

Interestingly, this Smoke Loader instance also downloads Raccoon Stealer and ZLoader.

Malsmoke is probably the most persistent malvertising campaigns we have seen this year. Unlike other threat actors, this group has shown that it can rapidly switch ad networks to keep their business uninterrupted.

Still using Internet Explorer?

Threat actors still leveraging exploit kits to deliver malware is one thing, but end users browsing with Internet Explorer is another. Despite recommendations from Microsoft and security professionals, we can only witness that there are still a number of users (consumer and enterprise) worldwide that have yet to migrate to a modern and fully supported browser.

As a result, exploit kit authors are squeezing the last bit of juice from vulnerabilities in Internet Explorer and Flash Player (due to retire for good next year).

Malwarebytes customers have long been protected from malvertising and exploit kits. We continue to track and report the campaigns we run into to help do our part in keeping the Internet safer.

Last week on Malwarebytes Labs, we dug into security hubris on the Lock and Code podcast, explored ways in which Apple’s notarization process may not be hitting all the right notes, and detailed a new web skimmer. We also explained how to keep distance learners secure, talked about PCI DSS compliance, and revealed that SMB security posture is weakened by COVID-19.

Stay safe, everyone!

The post A week in security (August 31 – September 6) appeared first on Malwarebytes Labs.

In August, Malwarebytes Labs analyzed the damage caused by COVID-19 to business cybersecurity. Because of immediate, mandated transitions to working from home (WFH), businesses across the United States suffered more data breaches, lost more dollars, and increased their overall attack surfaces, all while experiencing a worrying lack of cybersecurity awareness on behalf of workers and IT and security directors.

Today, we have parsed the data to understand the pandemic’s effect on, specifically, small- and medium-sized businesses (SMBs).

The data on SMB cybersecurity is troubling.

Despite smart maneuvering by some SMBs—like those that provided cybersecurity trainings focused on WFH threats, or those that refrained from rolling out a new software tool because of its security or privacy risks—28 percent of SMBs still paid unexpected expenses to address a malware attack, and 22 percent suffered a security breach due to a remote worker.

Those numbers are higher than the averages we found for companies of all sizes in August—by a respective 4 percent and 2 percent.

The numbers don’t look good. But perhaps more worrying than the actions that befell our respondents are the actions they might fail to take themselves. For example, while a majority of SMBs said that they planned to install a more permanent WFH model for employees in the future, the same number of SMBs said they did not plan to deploy an antivirus solution that can specifically protect those distributed workforces.

Further, while SMBs widely agreed that they were using more video conferencing, online communication, and cloud storage platforms during WFH—thus expanding their online attack surface—a worrying number of respondents said they did not complete any cybersecurity or online privacy reviews of those software tools before making them available to employees.

The cybersecurity posture of organizations of all sizes, including SMBs, can and should be taken seriously—especially as WFH becomes the new normal.

A closer look at SMB cybersecurity

Today’s data represents a follow-up to our August report, Enduring from Home: COVID-19’s Impact on Business Security, in which we surveyed more than 200 IT and cybersecurity executives, directors, and managers from businesses of all sizes. Our analysis today takes a magnifying glass to the more than 100 respondents who work for companies that have between 100 and 1,249 employees.

We separated the data into three bands according to company size: companies with 100–349 employees; companies with 350–699 employees; and companies with 700–1,249 employees.

At times, certain patterns or unique findings emerged within those bands.

For example, larger SMBs had far greater concerns about the effectiveness of a remote IT workforce. When asked about their biggest cybersecurity concerns with employees now working remotely, 50 percent of respondents working at companies with 700–1,249 employees said “our IT support may not be as effective in supporting remote workers.”

Respondents from smaller organizations, however, were not as concerned. Only 27.3 percent of respondents from the smallest businesses we surveyed (100–349 employees ) and 21.6 percent of midsized companies (350–699 employees) answered the same.

Intuitively, this makes sense—larger companies have more employees and more potential opportunities for ad-hoc cybersecurity and IT issues that should be addressed. But without an office, those issues might be ignored by employees. Similarly, those issues might become so frequent that they overwhelm remote IT workers.

Elsewhere in the data, in at least one situation, we found a potential correlation between company size and pandemic impact.

Like we said above, across all SMBs, 28 percent said they paid unexpected expenses to address a malware attack.

But that percentage increased depending on the size of the company affected. Surprise malware expenses hit 21.2 percent of companies with 100–349 employees, 29.7 percent of companies with 350–699 employees, and 30.4 percent of companies with 700–1,249 employees.

Maybe, then, there is some truth to the age-old saying: They bigger they are, the harder they fall.

Not every discovered trend was worrying, though.

Good trends in SMB cybersecurity

The immediate transition to WFH hit businesses everywhere, no matter their size. With no preparation time and sometimes lacking clarity from local and state governments for what was considered safe, businesses were forced to chart their own paths.

Despite these pressures, many SMBs rose to the occasion to protect their businesses and their employees, while also providing their workers with the tools and software necessary to succeed in their roles.

For example, 58.2 percent of respondents said their business provided work-issued devices as needed, and 41.4 percent said their business deployed previously unused software tools to maintain communication and productivity. Further, 56.9 percent of respondents said their business performed a cybersecurity and online privacy analysis of newly deployed software tools, while 21.6 percent said that those reviews led to a decision to not deploy a software tool.

Finally, 55.2 percent of respondents said their business provided cybersecurity trainings focused on the specific cybersecurity threats of WFH, with information on the importance of secured home networks, strong passwords, and unauthorized device access.

As SMBs showed promising action in the immediate transition to WFH, they also responded with encouraging preparations for the future.

More than half—56.9 percent—of respondents said their business would “develop stronger remote security policies,” 50 percent said their business would “host more cybersecurity trainings tailored for working from home,” and 48.2 percent said their business would “develop cybersecurity and online privacy reviews for new, necessary software in the transition to working from home.”

That last point is a welcome one. Though, as we showed, 56.9 percent of respondents said their business “performed a cybersecurity and online privacy analysis of any newly-deployed software tools,” those reviews may have been ad-hoc. Codifying these types of reviews into a broader set of policies is a good practice.

While all of these are encouraging trends, we cannot neglect some of the more worrying data points. In fact, one of our survey respondents accurately described some of same risks that we uncovered.

“Employees are not as vigilant as they would be working from home about potential cyber attacks,” said a Florida IT director at a company of 100 – 349 employees. “We’ve seen some lax efforts from some of our better more observant employees in the last few months.”

Conflicting postures in SMB cybersecurity

In our main report in August, we found potential cases of security hubris—the simple phenomenon in which a business believes it is more secure than it actually is. In our deeper analysis of SMB cybersecurity, similar trends emerged.

For example, when we asked SMB respondents to rank their preparedness to transition to WFH on a scale from 1–10, a majority ranked themselves highly—62 percent gave their business an 8 or higher, and 74.1 percent gave their business a 7 or higher.

However, our respondents’ actual transition to WFH did not involve the type of preparation and cybersecurity protection that would typically warrant such high evaluations.

Yes, 55.2 percent said they provided cybersecurity trainings focused on the specific cybersecurity threats of WFH, but think about the 44.8 percent who did not respond that way. Yes, 57 percent said they performed a cybersecurity and online privacy analysis of new software tools, but that likely means that more than 40 percent did not. Also, only 34.5 percent of respondents said they deployed a new antivirus tool for devices provided by the organization, which leaves us scratching our heads about the roughly 65 percent who did not say the same. What gives?

Amidst the transition to WFH, our SMB respondents entirely agreed on one aspect—they are using more tools, more frequently.

We found that 81.9 percent of SMB respondents said that their usage of video conferencing platforms, like Zoom, and Microsoft Teams, had increased “slightly more” or “significantly more,” 75 percent said the same about their increased use of online instant messaging platforms, and 69.8 percent said the same about their increased use of cloud storage platforms. Relatedly, 33 percent of respondents said they are using personal devices for work more often than their work-issued device, compared to the time before the pandemic.

Put into perspective, more software tools being used more frequently, with some employees reporting more frequent personal device usage, all points to one big problem—an increased attack surface.

And yet, even with this hard data showing an increased attack surface, 65.5 percent of respondents said their organizations were at least “equally secure” as they were before the pandemic; within those numbers, 35.4 percent went further, saying their business was actually “slightly more” or “significantly more” secure.

On our podcast Lock and Code, security evangelist and Malwarebytes Labs director Adam Kujawa explained why these positions are likely impossible to square.

“For the most part, I don’t see how people can actually say they’re more secure,” Kujawa said about the results from our broader COVID-19 report in August. “There may be an idea that, because folks are distributed—because remote workers are no longer located in a single, physical space—that they are somehow decentralized, and therefor harder to gain access to by cybercriminals.”

Kujawa continued: “The reality is that that is complete baloney.”

The clearest discrepancy between the words and the actions of SMBs came in the responses to their future. When asked about future plans to protect their businesses, 54.3 percent of SMB respondents said they would “install a more permanent work-from-home model for employees who do not need to be in the office every day.” However, just 38.8 percent said they would “deploy an antivirus solution that can better handle a more dispersed, remote workforce.”

This is disappointing because it seems so obvious. Any plans to install a more permanent workforce must include plans to protect that workforce.

Future proof

The advice that we offer to bolster SMB cybersecurity is similar to the advice we had for businesses of all sizes that were hit by the pandemic. Companies can come in many, many sizes, but none of those sizes are too small to care about cybersecurity.

You can read the full report to get a better understanding of those steps. In the meantime, though, if you’re really stumped, seriously, consider an antivirus solution.  

The post SMB cybersecurity posture weakened by COVID-19, Labs report finds appeared first on Malwarebytes Labs.

PCI DSS is short for Payment Card Industry Data Security Standard. Every party involved in accepting credit card payments is expected to comply with the PCI DSS. The PCI Standard is mandated by the card brands, but administered by the Payment Card Industry Security Standards Council (PCI SSC). The standard was created to increase controls around cardholder data to reduce credit card fraud.

The PCI Security Standards Council’s mission is to enhance global payment account data security by developing standards and supporting services that drive education, awareness, and effective implementation by stakeholders.

Compliance will ensure that a company can uphold a positive image and build consumer trust. This also helps build consumer loyalty, since customers are more likely to return to a service or product from a company they consider to be trustworthy.

What exactly is PCI DSS?

PCI DSS is an international security standard that was developed in cooperation between several credit card companies. The PCI DSS tells companies how to keep their card and transaction data safe.

When the PCI DSS was published in 2004, it was expected that organizations would achieve effective and sustainable compliance within about five years. Some 15 years later, less than half of organizations maintain programs that prevent PCI DSS security controls from falling out of place within a few months after formal compliance validation. According to a 2019 Verizon Payment Security Report, research shows that PCI sustainability is trending downward since 2017.

An increase in online transactions

One of the side effects of the COVID-19 pandemic has been an increase in online transactions. As more people worldwide have started to work from home and practice social distancing to combat the spread of COVID-19, businesses must prepare to handle a higher percentage of online transactions.

After all, it is likely that these online customers will continue to shop online when they learn to appreciate the ease of use, especially if they are confident about the security of their online transactions. However, with this rise in the frequency of digital payments comes the increased threat of data breaches and digital fraud.

The elements of compliance

A recent Bank of America report states that small businesses are protecting themselves by implementing industry security standards, like PCI compliance. Specifically, PCI Compliance Requirement 5 indicates that you must protect all systems against malware and regularly update anti-malware software. PCI DSS Requirement 5 has four distinct elements that imply they need to be addressed daily:

• 5.1: For a sample of system components, including all operating system types commonly affected by malicious software, verify that anti-malware software is deployed.
• 5.2.b: Examine anti-malware configurations, including the master installation of the software, to verify anti-malware mechanisms are configured to perform automatic updates and periodic scans.
• 5.2.d: Examine anti-malware configurations, including the master installation of the software and a sample of system components, to verify that the anti-malware’s software log generation is enabled, and logs are retained per PCI DSS Requirement 10.7.
• 5.3.b: Examine anti-malware configurations, including the master installation of the software and a sample of system components, to verify that the anti-malware software cannot be disabled or altered by users.

Basically, this boils down to our regular advice pillars:

• Make sure software (including anti-malware) is updated.
• Perform automatic and/or periodic scans for malware.
• Log and retain the results of those scans.
• Make sure protection software (especially anti-malware) can’t be disabled.

Common problems and objections

The first requirement (5.1) requires an organization to maintain an accurate inventory of their devices and the operating systems on those devices. However, configuration management database (CMDB) solutions are notorious for not being completely implemented. As a result, it can be quite an exercise to determine if every system that needs anti-malware software is installed. If so, look for a solution that provides an inventory of protected endpoints for you. You may use such an inventory for auditing your CMDB and verifying compliance.

The next hurdle with requirement 5.1 is that we still run into pushback from macOS and Linux users/administrators over their need to run an antivirus solution. Yet, a review of the CVE database debunks those claims.

Yes, these OSes have fewer vulnerabilities than Windows. However, they would still be “commonly affected,” given the number of vulnerabilities and the frequency with which those vulnerabilities are published. And as we have reported in the past, Mac threat detections are on the rise and actually outpace Windows in sheer volume. Using a solution that can cover all the operating systems in use in your organization can help you organize and control all your devices without adding extra software.

Sometimes, you will get pushback from server administrators who swear that any antivirus solution takes too much CPU to run and adversely affects server performance. While it’s getting better, we still regularly encounter people who make this claim but then fail to provide documented proof. (Not that we don’t believe them, as there are several legacy antivirus programs that can adversely affect performance.)

However, in most cases, the person is making these claims based on past experiences and not on trials of a more contemporary solution. No matter how you look at this, you will have to deploy anti-malware on Windows, macOS, and Linux Server endpoints to meet the PCI DSS.

Why compliance matters

Data from the Verizon Threat Research Advisory Center (VTRAC) demonstrates that a compliance program without the proper controls to protect data has a more than 95 percent probability of not being sustainable and is more likely to be the potential target of a cyberattack.

The costs of a successful cyberattack are not limited to liabilities and loss of reputation. There are also repairs to be made and reorganizations may be necessary, especially when you are dealing with ransomware or a data breach.

A data breach also involves lost opportunities and competitive disadvantages that are near impossible to quantify. The 2019 IBM/Ponemon Institute study calculated the cost of a data breach at $242 per stolen record, and more than $8 million for an average breach in the US. Ransomware is the biggest financial threat of all cyberattacks, causing an estimated $ 7.5 billion in damage in 2019 for the US alone.

For those companies engaged in online transactions, reputational damage can be fatal. Imagine customers shying away from the payment portal as soon as they spot your logo. PCI compliance, then, is not just a regulation—it could quite literally save your company’s bacon.

So stay safe (which in this case means staying compliant)!

The post PCI DSS compliance: why it’s important and how to adhere appeared first on Malwarebytes Labs.

With the pandemic still in full swing, educational institutions across the US are kicking off the 2020–2021 school year in widely different ways, from re-opening classrooms to full-time distance learning. Sadly, as schools embracing virtual instruction struggle with compounding IT challenges on top of an already brittle infrastructure, they are nowhere near closing the K-12 cybersecurity gap.

Kids have no choice but to continue their studies within the current social and health climate. On top of this, they must get used to new learning setups—possibly multiple ones—whether they’re full-on distance learning, homeschooling, or a hybrid of in-class and home instruction.

Regardless of which of these setups school districts, parents, or guardians decide are best suited for their children, one thing should remain a priority: the overall security of students’ learning experience during the pandemic. For this, many careful and considerable preparations are needed.

New term, new terms

Parents in the United States are participating in their children’s learning like never before—and that was before the pandemic forced their hand. Now more than ever, it’s important to become familiar with the different educational settings to consider which is best suited for their family.

Full-on distance learning

Classes are held online while students are safe in their own homes. Teachers may offer virtual classes out of their own homes as well, or they may be using their empty classrooms for better bandwidth.

This setup requires families to have, ideally, a dedicated laptop or computer students can use for class sessions and independent work. In addition, a strong Internet connection is necessary to support both students and parents working from home. However, children in low-income families may have difficulties accessing this technology, unless the school is handing out laptops and hot spot devices for Wi-Fi. Often, there are delays distributing equipment and materials—not to mention a possible learning curve thanks to the Digital Divide.

Full-on distance learning provides children with the benefit of teacher instruction while being safe from exposure to the coronavirus.

Homeschool learning or homeschooling

Classes are held at home, with the parent or guardian acting as teacher, counselor, and yes, even IT expert to their kids. Nowadays, this setup is often called temporary homeschooling or emergency homeschooling. Although this is a viable and potentially budget-friendly option for some families, note that unavoidable challenges may arise along the way. This might be especially true for older children who are more accustomed to using technology in their studies.

This isn’t to say that the lack of technology use when instructing kids would result in low quality of learning. In fact, a study from Tilburg University [PDF] on the comparison between traditional learning and digital learning among kids ages 6 to 8 showed that children perform better when taught the traditional way—although, the study further noted, that they are more receptive to digital learning methods. But perhaps the most relevant implication from the study is this: The role of teachers (in this article’s context, the parents and guardians) in achieving desirable learning outcomes continues to be a central factor.

Parents and guardians may be faced with the challenge of out-of-the-box-thinking when it comes to creating valuable lessons for their kids that target their learning style while keeping them on track for their grade level.

Hybrid learning

This is a combination of in-class and home instruction, wherein students go to school part-time with significant social distancing and safety measures, such as wearing masks, regular sanitizing of facilities and properties, and regular cleaning of hands. Students may be split into smaller groups, have staggered arrival times, and spend only a portion of their week in the classroom.

For the rest of students’ time, parents or guardians are tasked with continuing instruction at home. During these days or hours, parents or guardians must grapple with the same stressors on time, creativity, patience, and digital safety as those in distance learning and homeschooling models.

New methods of teaching and learning might be borne out of the combination of any or all three setups listed above. But regardless of how children must continue their education—with the worst or best of circumstances in mind—supporting their emotional and mental well-being is a priority. To achieve peace of mind and keep students focused on instruction, parents must also prioritize securing their children’s devices from online threats and the invasion of privacy.

Old threats, new risks

It’s a given that the learning environments that expose children to online threats and risk their privacy the most involve the use of technology. Some are familiar, and some are born from the changes introduced by the pandemic. Let’s look at the risk factors that make K-12 cybersecurity essential in schools and in homes.

Zoombombing. This is a cyberthreat that recently caught steam due to the increased use of Zoom, a now-popular web conference tool. Employees, celebrities, friends, and family have used this app (and apps like it) to communicate in larger groups. Now it’s commonly adopted by schools for virtual instruction hours.

Since shelter-in-place procedures were enforced, stories of Zoombombing incidents have appeared left and right. Take, for example, the case of the unknown man who hacked into a Berkeley virtual class over Zoom to expose himself to high school students and shout obscenities. What made this case notable was the fact that the teacher of that class followed the recommended procedures to secure the session, yet a breach still took place.

Privacy issues. When it comes to children’s data, privacy is almost always the top issue. And there are many ways such data can be compromised: from organizational data breaches—something we’re all too familiar with at this point—to accidental leaking to unconsented data gathering from tools and/or apps introduced in a rush.

An accidental leaking incident happened in Oakland when administrators inadvertently posted hundreds of access codes and passwords used in online classes and video conferences to the public, allowing anyone with a Gmail account to not only join these classes but access student data.

In April 2020, a father filed a case against Google on behalf of his two kids for violating the Children’s Online Privacy Protection Act (COPPA) and the Biometric Information Privacy Act (BIPA) of Illinois. The father, Clinton Farwell, alleges that Google’s G Suite for Education service collects the data—their PII and biometrics—of children, who are aged 13 and below, to “secretly and unlawfully monitor and profile children, but to do so without the knowledge or consent of those children’s parents.”

This happened two months after Hector Balderas, the attorney general of New Mexico, filed a case against the company for continuing to track children outside the classroom.

Ransomware attacks. Educational institutions aren’t immune to ransomware attacks. Panama-Buena Vista Union School. Fort Worth Independent. Crystal Lake Community High School. These are just some of the total districts—284 schools in all—that were affected by ransomware from the start of 2020 until the first week of April. Unfortunately, the pandemic won’t make them less of a target—only more.

With a lot of K-12 schools adjusting to the pandemic—often introducing tools and apps that cater to remote learning without conducting security audits—it is almost expected that something bad is going to happen. The mad scrambling to address the sudden change in demand only shows how unprepared these school districts were. It’s also unfortunate that administrative staff have to figure things out and learn by themselves on how to better protect student data, especially if they don’t have a dedicated IT team. And, often, that learning curve is quite steep.

Phishing scams. In the context of the education industry, phishing scams have always been an ever-present threat. According to Doug Levin, the founder and president of the K-12 Cybersecurity Resource Center, schools are subjected to “drive-by” phishing, in particular.

“Scammers and criminals really understand the human psyche and the desire for people to get more information and to feel in some cases, I think it’s fair to say in terms of coronavirus, some level of panic,” Levin said in an interview with EdWeek. “That makes people more likely to suspend judgment for messages that might otherwise be suspicious, and more likely to click on a document because it sounds urgent and important and relevant to them, even if they weren’t expecting it.”

Security tips for parents and guardians

To ensure distance learning and homeschooled students have an uninterrupted learning experience, parents or guardians should make sure that all the tools and gadgets their kids use to start school are prepared. In fact, doing so is similar to how to keep work devices secure while working from home. For clarity’s sake, let’s flush out some general steps, shall we?

Secure your Wi-Fi

• Make sure that the router or the hotspot is using a strong password. Not only that, switch up the password every couple months to keep it fresh.
• Make sure that all firmware is updated.
• Change the router’s admin credentials.
• Turn on the router’s firewall.

Secure their device(s)

• Make sure students’ computers or other devices are password-protected and lock automatically after a short period of time. This way, work won’t be lost by a pet running wild or a curious younger sister smashing some buttons.

  For schools that issue student laptops, the most common operating system is ChromeOS (Chromebooks). Here’s a simple and quick guide on how parents and guardians can lock Chromebooks. The password doesn’t need to be complicated, as you and your child should be able to remember it. Decide on a pass phrase together, but don’t share it with the other kids in the house.

• Ensure that the firewall is enabled in the device.
• Enforce two-factor authentication (2FA).
• Ensure that the device has end-point protection installed and running in real time.

Secure your child’s data

• Schools use a learning management solution (LMS) to track children’s activities. It is also what kids use to access resources that they need for learning.

  Make sure that your child’s LMS password follows the school’s guidelines on how to create a high entropy password. If the school doesn’t specify strong password guidelines, create a strong password yourself. Password managers can usually do this for you if you feel that thinking up a complicated one and remembering it is too much of a chore.

• It also pays to limit the use of the device your child uses for studying to only schoolwork. If there are other devices in the house, they can be used to access social media, YouTube, video games, and other recreational activities. This will lessen their chances of encountering an online threat on the same device that stores all their student data.

Secure your child’s privacy

There was a case before where a school accidentally turned the cameras on of school-issued devices the students were using. It blew up in the news because it greatly violated one’s privacy. Although this may be considered a rare incident, assume that you can’t be too careful when the device your kid uses has a built-in camera.

Students are often required to show their faces on video conference software so teachers know they are paying attention. But for all the other time spent on assignments, it’s a good idea to cover up built-in cameras. There are laptop camera covers parents or guardians can purchase to slide across the lens when it’s not in use.

New challenges, new opportunities to learn

While education authorities have had their hands full for months now, parents and guardians can do their part, too, by keeping their transition to a new learning environment as safe and frictionless as possible. As you may already know, some states have relaxed their lockdown rules, allowing schools to re-open. However, the technology train has left the station.

Even as in-person instruction continues, educational tech will become even more integral to students’ learning experiences. Keeping those specialized software suites, apps, communication tools, and devices safe from cyberthreats and privacy invasions will be imperative for all future generations of learners.

Safe, not sorry

While IT departments in educational institutions continue to wrestle with current cybersecurity challenges, parents and guardians have to step up their efforts and contribute to K-12 cybersecurity as a whole. Lock down your children’s devices, whether they use them in the classroom or at home. True, it will not guarantee 100 percent protection from cybercriminals, but at the very least, you can be assured that your kids and their devices will remain far out of reach.

Stay safe!

The digital credit card skimming landscape keeps evolving, often borrowing techniques used by other malware authors in order to avoid detection.

As defenders, we look for any kind of artifacts and malicious infrastructure that we might be able to identify to protect our users and alert affected merchants. These malicious artifacts can range from compromised stores to malicious JavaScript, domains, and IP addresses used to host a skimmer and exfiltrate data.

One such artifact is a so-called “gate,” which is typically a domain or IP address where stolen customer data is being sent and collected by cybercriminals. Typically, we see threat actors either stand up their own gate infrastructure or use compromised resources.

However, there are variations that involve abusing legitimate programs and services, thereby blending in with normal traffic. In this blog, we take a look at the latest web skimming trick, which consists of sending stolen credit card data via the popular instant messaging platform Telegram.

An otherwise normal shopping experience

We are seeing a large number of e-commerce sites attacked either through a common vulnerability or stolen credentials. Unaware shoppers may visit a merchant that has been compromised with a web skimmer and make a purchase while unknowingly handing over their credit card data to criminals.

Skimmers insert themselves seamlessly within the shopping experience and only those with a keen eye for detail or who are armed with the proper network tools may notice something’s not right.

The skimmer will become active on the payment page and surreptitiously exfiltrate the personal and banking information entered by the customer. In simple terms, things like name, address, credit card number, expiry, and CVV will be leaked via an instant message sent to a private Telegram channel.

Telegram-based skimmer

Telegram is a popular and legitimate instant messaging service that provides end-to-end encryption. A number of cybercriminals abuse it for their daily communications but also for automated tasks found in malware.

Attackers have used Telegram to exfiltrate data before, for example via traditional Trojan horses, such as the Masad stealer. However, security researcher @AffableKraut shared the first publicly documented instance of a credit card skimmer used in Telegram in a Twitter thread.

The skimmer code keeps with tradition in that it checks for the usual web debuggers to prevent being analyzed. It also looks for fields of interest, such as billing, payment, credit card number, expiration, and CVV.

The novelty is the presence of the Telegram code to exfiltrate the stolen data. The skimmer’s author encoded the bot ID and channel, as well as the Telegram API request with simple Base64 encoding to keep it away from prying eyes.

The exfiltration is triggered only if the browser’s current URL contains a keyword indicative of a shopping site and when the user validates the purchase. At this point, the browser will send the payment details to both the legitimate payment processor and the cybercriminals.

The fraudulent data exchange is conducted via Telegram’s API, which posts payment details into a chat channel. That data was previously encrypted to make identification more difficult.

For threat actors, this data exfiltration mechanism is efficient and doesn’t require them to keep up infrastructure that could be taken down or blocked by defenders. They can even receive a notification in real time for each new victim, helping them quickly monetize the stolen cards in underground markets.

Challenges with network protection

Defending against this variant of a skimming attack is a little more tricky since it relies on a legitimate communication service. One could obviously block all connections to Telegram at the network level, but attackers could easily switch to another provider or platform (as they have done before) and still get away with it.

Malwarebytes Browser Guard will identify and block this specific skimming attack without disabling or interfering with the use of Telegram or its API. So far we have only identified a couple of online stores that have been compromised with this variant, but there are likely several more.

As always, we need to adapt our tools and methodologies to keep up with financially-motivated attacks targeting e-commerce platforms. Online merchants also play a huge role in derailing this criminal enterprise and preserving the trust of their customer base. By being proactive and vigilant, security researchers and e-commerce vendors can work together to defeat cybercriminals standing in the way of legitimate business.

This week on Lock and Code, we discuss the top security headlines generated right here on Labs and around the Internet. In addition, we talk to Adam Kujawa, security evangelist and director of Malwarebytes Labs, about “security hubris,” the simple phenomenon in which businesses are less secure than they actually believe.

Ask yourself, right now, on a scale from one to ten, how cybersecure are you? Now, do you have any reused passwords for your online accounts? Does your home router still have its default password? If your business rolled out new software for you to use for working from home (WFH), do you know if those software platforms are secure?

If your original answer is looking a little more shaky, don’t be surprised. That is security hubris

Tune in to hear about the dangers of security hubris to a business, how to protect against it, and about how Malwarebytes found it within our most recent report, “Enduring from home: COVID-19’s impact on business security,” on the latest episode of Lock and Code, with host David Ruiz.
