[wp-hackers] Admin Login Brute Force Attacks

[Abdussamad Abdurrazzaq]

I do the blocking server side with fail2ban and a modified version of wp 
fail2ban plugin:

The advantage of this approach is that if you have a multisite 
installation all failed login attempts at all sites are taken into 
account. Also it's more efficient to block at the firewall level than at 
the application level.
