FYI, the past month there were a couple of (quite long) threads on this
thing on bugtraq and incidents @securityfocus.
It seems to be some worm that scans for weak passwords, someone on
incidents published a webpage on this stuff here:
http://www.jaenicke.org/sk/ with the binaries used and an irc log chatting
with one of the kiddies.
The sources seems to mainly be cracked boxes with, aemh... blank root
passwords.
(everytime I read the previous 3 words together I shudder, apologies if
they have the same effect on you :)

I've just moved the public port of the sshd on another port, quite lame
but at least I'm not bothered by worms :)
