An anonymous reader quotes a report from Ars Technica: FishPig, a UK-based maker of e-commerce software used by as many as 200,000 websites, is urging customers to reinstall or update all existing program extensions after discovering a security breach of its distribution server that allowed criminals to surreptitiously backdoor customer systems. The unknown threat actors used their control of FishPig's systems to carry out a supply chain attack that infected customer systems using FishPig's fee-based Magento 2 modules with Rekoobe, a sophisticated backdoor discovered in June. Rekoobe masquerades as a benign SMTP server and can be activated by covert commands related to handling the startTLS command from an attacker over the Internet. Once activated, Rekoobe provides a reverse shell that allows the threat actor to remotely issue commands to the infected server. "We are still investigating how the attacker accessed our systems and are not currently sure whether it was via a server exploit or an application exploit," Ben Tideswell, the lead developer at FishPig, wrote in an email. "As for the attack itself, we are quite used to seeing automated exploits of applications and perhaps that is how the attackers initially gained access to our system. Once inside though, they must have taken a manual approach to select where and how to place their exploit." FishPig is a seller of Magento-WordPress integrations. Magento is an open source e-commerce platform used for developing online marketplaces. The supply-chain attack only affects paid Magento 2 modules. Tideswell said the last software commit made to its servers that didn't include the malicious code was made on August 6, making that the earliest possible date the breach likely occurred. Sansec, the security firm that discovered the breach and first reported it, said the intrusion began on or before August 19. Tideswell said FishPig has already "sent emails to everyone who has downloaded anything from FishPig.co.uk in the last 12 weeks alerting them to what's happened." Tideswell declined to say how many active installations of its paid software there are. This post indicates that the software has received more than 200,000 downloads, but the number of paid customers is smaller. In a disclosure published after the Sansec advisory, FishPig describes how the intruders pulled off the intrusion and remained hidden for so long.
