Here’s another reason to change your WordPress default login name from admin to something only you know: my logs show that my site keeps getting constant admin login attempts from IP Address 188.8.131.52 in St. Petersburg, Russia and it’s apparently coming from various browsers. (Distributed dictionary attack coming from various computers behind a firewall perhaps?) Anybody else having issues with illegal activity from this IP?
This is not the only address that keeps trying to login as admin, but it is the one that does it repeatedly, every day. Most likely just a script of a criminal trying to penetrate many unprotected WordPress sites by running dictionary attacks.

EDIT November 24, 2011 – the admin login attempts from this IP address have stopped. Meanwhile I installed the “Limit Login Attempts” plugin described in the links above for extra protection.
