That's funny, I had atleast one person here receive a similar email which was forwarded on to me. I ran it through McAfee (4.5.1 engine, 4.0.4280 DAT) and it picked it right up (Trojan Name: Exploit-Code Base http://us.mcafee.com/virusInfo/default.asp?id=description&virus_k=99383). Potentially it's a different incident than what they are talking about but the admin@domainname and the attachment are similar (it was a zip file containing an html file [according to the extensions]).

I have had like 4 users call and tell me that they're receiving email from admin@ourdomainname with a unidentified attachment, possibly a worm that exploits the new Microsoft vulnerability last week, all 4 of these people reported that their updated this morning antivirus software missed it.
FYI.
