A new malware disguised as a caching plugin is targeting WordPress sites, allowing threat actors to gain control over the site. The malware functions as a backdoor, enabling the management of plugins, content replacement, and redirecting users to malicious locations. It disguises itself as a legitimate plugin to avoid detection. Website owners are advised to use strong credentials, keep plugins updated, and remove unused add-ons and users.
