• Posting this as a public service alert and to provide a place for others to report same issue. Two other sites are affected as of 2018.01.10, both reporting here on *Wordpress.com* forum: my-wordpress-username-has-changed-to-html404

    My client’s admin account was hacked this morning. Symptom: admin user account name replaced with ‘html404’

    Site is running a selfhosted version of wordpress, 4.9.2, NOT tied to a wordpress.com account.

    I immediately:
    – logged in and confirmed user html404 appeared in user list.
    – opened the html404 user profile in the profile editor
    – logged user out of all sessions
    – changed the user email and password
    – created another admin profile to replace the hacked profile
    – deleted the hacked profile, attributing all its content to the new
    admin profile

    I’m still in the process of conducting a forensic analysis on the website access logs. Will post findings on this thread.
