Hopefully, I've replied individually with the sig to each person who's asked on- and off-list (many have). I'd initially written that I would rather not post it to the list because the public nature of the archives may make it too easy for a novice bot author to turn out a new variant that the sig misses. If few feel that risk remains, I'll be happy to post it here. Barbara Tibbs wrote:

Am not sure posting it here would be wise - too many lurkers who might like to subtly alter this overused variant to counter the sig. When this triggers an alert on your SNORT, the bot is just waking up and still benign (relatively speaking) and can be removed before the 'owner' wakes them up and uses them to do harm. H.

A number of PCs were hit with it and they began attempting to brute force the passwords for (all of ?) the accounts in our Active Directory. We'd just implemented a domain account lockdown policy -- a short lockdown period -- after a somewhat high number of unsuccessful login attempts so we began to see the effects of the new lockdown policy kick into effect rather quickly (some users reported their accounts would lock out for the lockdown period). The infected PCs would show up in the security event log of other computers and the active directory servers with high numbers of unsuccessful login attempts on various accounts. - H.
