Hi Jay

That is the worm known as I-worm.music.d

Have a look at fsecure's (borrowed from Eugene Kaspersky) description
here:
http://www.f-secure.com/v-descs/music.htm
or viruslist's:
http://www.viruslist.com/eng/viruslist.asp?id=4117&key=000010001300001
00047

Yours is a variant of this one.

Cheers,
Brad

Hi folks,

        I figured I'd pass this along for consideration and review.  The
following was received at a staff distribution address at another
site.
While I haven't confirmed this is a genuine Outlook trojan/worm, it
has
all the markings of such.  Namely:

        1.      The message was unsolicited

        2.      Tell-tale generic subject and body

        3.      Microsoft executable payload; the payload (wishyou.zip)
                contains Music.exe.  Interested parties can snag a copy of
                the binary at http://www.treachery.net/~jdyson/wishyou.zip

        4.      Sender was using Microsoft Outlook Express (which is
                notoriously vulnerable to this sort of thing)

        A cursory review of the binary indicated that the executable calls
wininet.dll.  Doubtful that a music player needs to initiate a
connection
to the internet (all wisecracks about RealPlayer mercifully set
aside).

        Here's the sanitized headers:
