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.

I've just moved the public port of the sshd on another port, quite lame but at least I'm not bothered by worms :) HTH Frankye -- Frankye Fattarelli |U| |P| |S|F| frankye.DIESPAMMERSDIE@ipv5.net |R| |S| |Y|I| this email is RFC 3514 compliant |G| |H| |N|N|
