Infosecurity Magazine reports a supply chain attack in which attackers poisoned a JSON feed used by bdThemes WordPress plugins.

WordPress sites running the vendor's plugins were affected.
Malcious Admin Menu Editor Pro plugin backdoors 1,500 WordPress sites
Compromised Admin Menu Editor Pro update server distributed backdoored plugin versions installing web shells and hidden admin accounts on roughly 1,500 WordPress sites.
A threat actor with root-level access to adminmenueditor.com pushed trojanized Admin Menu Editor Pro versions 2.35 and 2.36 containing includes/wp-user-consent.php, which installed a web shell and created a hidden wp_-prefixed user account. At least 230 customers and roughly 1,500 sites installed the malicious update, with several hundred more downloads possibly affected. Developer Janis Elsts took the site offline after the attacker recompromised the clean 2.36 release; version 2.34 and the free plugin are believed unaffected.
