Malcious Admin Menu Editor Pro plugin backdoors 1,500 WordPress sites

Malicious versions of the Admin Menu Editor Pro plugin for WordPress have been distributed to more than 200 customers after a threat actor compromised the maintainer’s website and pushed updates that created a hidden user account.

Developer Janis Elsts says an unauthorized party accessed the adminmenueditor.com website on Monday and uploaded version 2.35 as an update for the plugin’s Pro version. The update included an includes/wp-user-consent.php file that installed a web shell on affected websites.

After noticing the intrusion, Elsts removed the malicious update and pushed a clean version 2.36 on the same day at 19:00 UTC. However, the hacker still had access to the website and compromised the new version, too.
