Payment-card-skimming Magecart strikes again: Zero out of five for infecting e-retail sites
Customer ratings plugin treated to a malicious rewrite to swipe entered banking info
The payment-card-skimming malware operation dubbed Magecart has turned up again, this time in Shopper Approved, a customer rating plugin for websites.
Shopper Approved is a toolkit used by hundreds of e-commerce sites, and it was infected with the MageCart spyware, allowing crooks to siphon off bank card data entered into webpages using the customer-rating plugin, infosec biz RiskIQ reported this week. The infection, first spotted on September 15, closely resembles the cyber-attack that emerged over the summer against Ticketmaster rather than the later and more sophisticated, and high profile, raid on British Airways passengers.
Initially, in this case, the data thieves made a mistake, and the card-slurping code was left clearly noticeable. However, the mistake was quickly spotted and quietly sorted by the crooks.
It's going to get worse
Magecart refers to a toolkit of malicious software and half a dozen groups of miscreants deploying this code, rather than a single group of cybercriminals. “The six groups under Magecart have ramped up their operations, becoming more clever, and in many cases, sophisticated, with each attack,” RiskIQ's Yonathan Klijnsma warned.
"Magecart groups are carrying out a full-scale assault on e-commerce and show zero signs of stopping. These attacks are only getting more and more traction as the groups learn how to become more effective."
RiskIQ worked with Shopper Approved to block and remediate the infection, which was curtailed by mid September. This cleared the way for RiskIQ to go public with its findings on Tuesday this week.

El Reg asked US-based Shopper Approved to explain what how it was handling the fallout of network intrusion, and what advice it had for its customers.
"Upon learning of the event, we promptly initiated an internal investigation, engaged a leading IT forensics firm to assist in our review and took steps to remediate the issue and enhance our security features for both our website and the Shopper Approved seal. Additionally, we have worked closely with researchers at RiskIQ to better understand the issue and help protect against similar events in the future," a Shopper Approved spokesperson told The Register in a statement.
"The incident only affected a small portion of our customers that use the Shopper Approved seal on their website, and we have reached out directly to those we believe may have been affected. The security of our systems and customers is a top priority for Shopper Approved, and we regret any inconvenience this incident may have caused." ®
Magecart is using more and more cunning techniques to evade detection, according to security researcher Willem de Groot, here.
