I appreciate all of the advice I've received so far, and from what it
seems, I'm in quite a sticky situation. I'm not 100% positive that the
"cracker" compromised any systems from this box. There is a txt file of
about 100 IPs with admin usernames/passes which I don't think would be a
good idea to post to a public list, especially a script-kiddie haven
like FD. I also know that the attacker performed a UDP flood on some
poor sap. Unfortunately for the attacker, we noticed this right away
when the T1 router went bezerk. I traced it back to that machine, not
by sniffing, but through switch activity lights, so I don't know who
that victim was. I thought it was a faulty NIC, or a driver gone
haywire, so I rebooted the box. That's when I noticed that mIRC.exe was
listening for remote commands, and a new admin account.
Judging from the date of the trojan files, they only had control for 2-3
days, and I promptly installed zonealarm, a temporary fix until I could
get the server replaced.
Anyway, the machine now sits happily in a corner, unplugged from the
world, with the HD just how I left it. Everything I deleted from the
machine, aside from the cracker's admin acount, was copied off to a
secure place. Hopefully that will be enough if I get any inquries. I
will start with a report to CERT, and see where that goes.
Thanks again for all the help.
