Credit card skimmer evades Virtual Machines

q-logger skimmer keeps Magecart attacks going

This blog post was authored by Jérôme Segura Although global e-commerce is continuing to grow rapidly, it seems as though Magecart attacks via digital skimmers have not followed the same trend.

Lil’ skimmer, the Magecart impersonator

This blog post was authored by Jérôme Segura A very common practice among criminals consists of mimicking legitimate infrastructure when registering new domain names. This is very true for Magecart threat actors who love to impersonate Google, jQuery and many other popular brands. In this post we look at a skimmer recently disclosed by security researc

Lock and Code S1Ep17: Journalism’s role in cybersecurity with Alfred Ng and Seth Rosenblatt

Most everything about cybersecurity—the threats, the vulnerabilities, the breaches and the blunders—doesn’t happen in a vacuum. And the public doesn’t learn about those things because threat actors advertise their exploits, or because companies trumpet their lackluster data security practices. No, we often learn about cybersecurity issues because of

Inter skimming kit used in homoglyph attacks

As we continue to track web threats and credit card skimming in particular, we often rediscover techniques we’ve encountered elsewhere before.

Is Your Chip Card Secure? Much Depends on Where You Bank

Chip-based credit and debit cards are designed to make it infeasible for skimming devices or malware to clone your card when you pay for something by dipping the chip instead of swiping the stripe. But a recent series of malware attacks on U.S.-based merchants suggest thieves are exploiting weaknesses in how certain financial institutions have implemented th

Web skimmer hides within EXIF metadata, exfiltrates credit cards via image files

They say a picture is worth a thousand words. Threat actors must have remembered that as they devised yet another way to hide their credit card skimmer in order to evade detection. When we first investigated this campaign, we thought it may be another one of those favicon tricks, which we had described in a previous blog. However, it turned out to be diff

Online credit card skimming increased by 26 percent in March

Criminals are known to take advantage of events that capture people’s attention. This is true for any kind of attack that relies on social engineering, such as the phishing emails exploiting the Covid-19 pandemic.

Fraudsters cloak credit card skimmer with fake content delivery network, ngrok server

Threat actors love to abuse legitimate brands and infrastructure—this, we know. Last year we exposed how web skimmers had found their way onto Amazon’s Cloudfront content delivery network (CDN) via insecure S3 buckets. Now, we discovered scammers pretending to be CDNs while exfiltrating data and hiding their tracks—another reason to keep watchful eye o

Hundreds of counterfeit online shoe stores injected with credit card skimmer

There’s a well-worn saying in security: “If it’s too good to be true, then it probably isn’t.” This can easily be applied to the myriad of online stores that sell counterfeit goods—and now attract secondary fraud in the form of a credit card skimmer. Allured by great deals on brand names, many people end up buying products on

There’s an app for that: web skimmers found on PaaS Heroku

Criminals love to abuse legitimate services—especially platform-as-a-service (Paas) cloud providers—as they are a popular and reliable hosting commodity used to support both business and consumer ventures. Case in point, in April 2019 we documented a web skimmer served on code repository GitHub. Later on in June, we observed a vast campaign where skimming
