While Magecart is well known as a malware hacking groups use to inject card-skimming scripts into e-commerce platforms, Prevailion researchers have detected many compromises with Magecart that suggest the malicious actors are not actually going after credit card data.
According to public data breach records, the credit card information of organizations from British Airways to NutriBullet, Tupperware, easyJet and Macy’s has been targeted in different card-skimming campaigns. In July 2019, attackers leveraged a vulnerability in the e-commerce software platform Magento, which left more than 960 online retailers compromised in a single digital skimming campaign.
Earlier this year, card-skimming groups began attacking industry verticals, going after the education sector. Parents and students found themselves victims of Magecart actors who exploited Blue Bear Software, “an administration and e-commerce platform for K-12 schools and other educational institutions,” according to Threatpost.
In large part, Magecart has been seen as a threat to online retailers, but this recent shift in targets suggests that the group’s objectives could be evolving. The car-skimming script has been used to steal credit card information during the checkout process by masquerading as payment forms, but the malicious script can be used to capture any submitted information, suggesting that it is likely being deployed within organizations for other purposes.
Recently, Twilio, a cloud communications company, suffered a breach that initially, “resembled a Magecart-style attack that skims websites for users’ financial data,” Cyber Scoop reported. Though Twilio, “cleaned up the code hours later, and said there was no sign the attackers had accessed customer data,” the larger concern is that the attackers had access to the code.
Once an organization is compromised by exploiting any attack vector, adversaries can linger undetected. When those actors are not financially motivated–which is often the case for nation state hackers–they are after more sensitive data. Of greater concern is that they are patient enough to take the time to find it. A network that is porous enough to be infiltrated and exfiltrated, is all too often unaware of the communication coming from the inside that is being sent out to the open web.
Recently, Prevailion’s cyberintelligence was able to identify Magecart malware in the World Health Organization’s network. When a global organization, such as WHO, collects and stores that much sensitive data, they are a target for malicious actors around the globe. The reality is, few users are visiting the WHO and making credit card purchases, which leads us to believe that this form-grabbing malware (able to capture any data entered into an online form) is being leveraged for more nefarious attacks. Though commodity malware is often underappreciated for its potential as a tool for APT groups, Prevailion’s Apex Platform tracks many other instances where it has indeed been deployed by APTs.
Prevailion’s CEO Karim Hijazi explained to Fox News, “This type of infection within the WHO network could be used to hack other organizations who visit the site — or any partners/registrants who are using the site to fill out forms and submit information or make requests.”.
Breached organizations continue to make headlines because they rely too much on security tools that don’t have visibility into real threats. The risk from human error is real and has an enormous impact on the business and its victims, and nation state adversaries are highly motivated.
