Brute Force Attack

Hi
Check your htaccess files to see if they have been modified
Also try running Anti-Malware from GOTMLS.NET. It works really well.

Do you know what type of hack it is?

Please define “attacked” and folks here can probably makes some specific suggestions. Remember that just because you hide or otherwise have a URL that does not exist, that does not stop attackers from trying to access it. MTN

There is nothing to do. If Wordfence is properly configured, it will manage the attacks.
