WordPress sites backdoored after FishPig supply chain attack • The Register

It’s only been a week or so, and obviously there are at least three critical holes in WordPress plugins and tools that are being exploited in the wild right now to compromise loads of websites.

We’ll start with FishPig, a UK-based maker of software that integrates Adobe’s Magento ecommerce suite into WordPress-powered websites. FishPig’s distribution systems were compromised and its products altered so that installations of the code semi-automatically downloaded and ran the Rekoobe Linux trojan.

Infosec outfit Sansec raised the alarm this week that FishPig’s software was acting weird: when a deployment’s control panel was visited by a logged-in Magento staff user, the code would automatically fetch and run from FishPig’s back-end systems a Linux binary that turned out to be Rekoobe. This would open a backdoor allowing miscreants to remotely control the box.

After that, the crooks could snoop on customers, alter or steal data, and so on.

Per FishPig’s disclosure, its products were altered as early as August 6, and the offending code has since been removed. We’re told that the paid-for versions were primarily affected. Free versions of FishPig modules available on GitHub were likely clean.

If you’re using FishPig’s commercial software, you should reinstall the tools and check for signs of compromise.

According to FishPig, it’s “best to assume that all paid FishPig Magento 2 modules have been infected.” It’s not known exactly how many customers were caught up in the supply-chain attack, though Sansec said the company’s free Magento packages have been collectively downloaded more than 200,000 times. That doesn’t necessarily mean there’s a comparable number of paid users, though it gives you an idea of the interest in FishPig’s tools.

While it’s not known exactly how the attackers broke into FishPig’s back-end servers, the outcome was…
