RE: New Virus? The AV Vendors respond (long post)

It would appear that the e-mail I described did in
fact hold an infected attachment.

Several list members have pointed out that I could
have done some analysis prior to submitting my post.
While this is true, it isn't as easy as some would
have us all believe. I'm not a malware guy, or even
a programmer, but an IDS guy. I don't tell folks to
analyse their own logs before they ask me to look
at something, since they may believe I might know
more than they do, but I digress. IMHO, there are
people on this list with far more expertise in
analyzing malware than I, which is why I made my
post without any attempt on my part to figure it
out...

Anyway, I've received some responses from some
AV vendors and thought I'd share. The unfortunate
thing is that, while they all agree it's malicious,
they don't agree as to what exactly it is. Here is
the list of direct responses I received:

Sophos - W32/MyDoom-Gen

CA - Win32.Qweasy.A (analyst comment says it may be
a MS05-039 worm...)

McAfee - BackDoor-CEB (extra.dat provided with their
response)

Here's the output from virustotal.com:

As you can see, nothing concrete using virus the
definitions available as of yesterday.

A number of folks asked me to send them a copy.
I only forwarded to one person though, since I
knew who they were. All other such requests, I
must apologize, will not be answered. Sorry.

I hope this information proves useful. If any
of you out there have s a more concrete answer
as to what this is, please share.
