Vietnam and Indonezia are also suspects in my list.
The biggest problem with this approach is that even tho I could ban
whole Asia and Russia, a significant part of the attacks do not
originate from there, but from countries like USA, UK, etc, controlled
by hackers (also) from the aforementioned areas...
The latest case of password breaking I had to deal with was from an
USA IP address.. they managed to insert an iframe in all index.html
and index.php files on the respective FTP account. The iframe however
was pointing to a .ru website hosted in France.. Isn't globalization
Anyway, just banning ranges of IP addresses may not enough, so to rely
on this _only_ would be careless.
