I have seen a little of this worm/trojan as well... same IP, Unreal v3.2 IRC server.
I am leaning to the same conclusion as Josh. Note: I said leaning, not completely convinced. I have seen in the IRC traffic some references to lsass, including what I think might be the command-line to instruct the infected machine to commence scanning -- "advscan lsass 100 5 1000 -b -r -s". Haven't had a chance to look at the executable with any detail yet... Also noticed this in the IRC traffic: "There are 1 users and 19496 invisible on 1 servers" and "ddos.random <IP Address> 10003 60 -s". I am not overly familar with IRC servers, so I am reviewing RFC2811 and Brocklesby's draft trying to understand the IRC traffic. We submitted our copy of wkssvrs.exe to Symantec, yesterday I believe. -bech -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Harlan Carvey Sent: Thursday, June 03, 2004 2:26 PM To: [EMAIL PROTECTED] Cc: Perrymon, Josh L.

If you don't know what the worm is, what would lead you to guess that the infection vector is LSASS? Is there some other piece of information that you're not sharing? _______________________________________________ Full-Disclosure - We believe in it.
