  • If a hacker is using your correct username to attempt to login to your site then this is major warning that he/she/it is already halfway through the door. I would advise that you create a new admin level user with a unique username and set a different nickname. Then delete your compromised username and assign all your existing content to your new user’s nickname. Finally, I would make sure that any sitemap plugin you are using is excluding author(s)/user(s) (SEO WordPress from Yoast has this option), and also prevent the enumeration of usernames in the site via https://yoursite.url/?author=1 . Many security plugins offer this feature (I’m not sure if it’s included in iThemes), or you can add a snippet of code to your .htaccess file (backup first). Take a look at this thread:

    Thanks Barnez,

    Although I’ve got the measures you mention already covered, I’m still not sure what to do if I get blocked out as a user? They work when I sleep, so I’m too late to take measures. I could ad another admin account but that’s giving them more opportunities to log in.

    It’s happened to me in the past when somehow my username became known and I could see it listed in the failed login attempts. I created a new user and nickname and deleted the old admin account. Since then my username has remained confidential and hasn’t shown up on the failed login records.

    One more point to remember is that failed logins are usually blocked by IP address, and not by username. So in that case the attempted hacker breaks the rules for the number of failed logins allowed and the IP address is blocked for a specified period of time. The problem arises when this is a network of different IP addresses, in which case once one IP is blocked another compromised computer in a different location and with a different IP address takes over and continues to try and break your password.

    I would create a new user account and nickname, delete your existing compromised user account, use strong 15+ mixed character/symbol passwords and tighten your login rules in iThemes.
