Need BOGIES list

[Geoff White <geoffw () cybertribe com>]

Hello All.
I'm having trouble with Cracking Attempts  and DoS attacks from a lot of 
places in China :)
My client doesn't do any business in that region so they don't mind If I 
block the entire sub-continent :)
Does anyone have a bad-guy list (or part of one) that I can use to get 
started?
I'm using pf under OpenBSD 3.7 as a firewall box.
E-mailing me off line is fine
