Dudez, wtf is up with this trojan/hack/bot/win2k exploit that seems to be
speading itself fairly rapidly.  Is there a sig for this yet?  Does anyone
even know how this thing is being spread??

Everyone I've talked to seems to think it spreads through
weak or nonexistent w2k Administrator passwords. If that
is the case, a signature that looks for netbios over tcp
connections to port 139 with the Administrator account 
trying to access the C$ share should do the trick.
