Downadup's Password Cracking List

This week it was reported that the Downadup worm (also known as Conficker) has infected 3.5 million Windows machines, according to data gathered by security company F-secure. One the ways the worm tries to propagate is by guessing account passwords on the victim machine.

F-secure has a write-up on the worm which includes the list of passwords that it checks (reproduced below). The list of just over 180 passwords candidates contains the usual suspects - the username for the account, repeated digits, qwerty, admin, password and pass1, pass12, pass123. Given that the worm has successfully infected such a large number of machines, this password guessing stragegy must be quite effective. So weak passwords are still letting us down.

(Added April 2nd, 2009: you can see a nice graphic of this password list at Graham Cluley's blog).
