Attacker Bought 30 WordPress Plugins on Flippa and Backdoored All of Them
An attacker acquired the Essential Plugin portfolio, comprising over 30 WordPress plugins, and embedded a backdoor that injected spam into compromised sites. The attack exploited a supply chain vulnerability, allowing a trusted reputation to facilitate the insertion of malicious code without triggering review processes. This incident underscores the need for improved security measures in software ecosystems, as similar patterns have been observed in other platforms.
