Three servers I maintain receive about 60 of those dumb and ridiculous login
attempts per hour. They are not running any Tor relay und are not especially
'big' in terms of number of users or publicity. Clearly, the originator does
not target Tor nodes specifically. ;-) As these logins are coordinated (same
username on 3 machines within the same second), it seems to be some botnet.
Concerning the aspect of using Tor to target others: I would be very surprised
if anyone actually tries to use Tor for this, ordinary botnets of owned
machines are completely sufficient.
