on my site i'm getting bruteforce attempts for some time, it's always 4 - 5 login attempts on fronted in a minute, from different IP's with same login. From access logs i see that the form is accessed trough ?option=com_users&view=login. Is there a way to completely block login page (the site has no other users, only one admin)? Maybe that's possible with WAF Blacklist? Or maybe there's other way? Thank you in advance.
