[Esa-l] New variant of Hybris?

I just got a message in my inbox that looked really suspicious: a
message with an executable attachment named AKBHIJAK.EXE, but no body,
To: or Subject: line. Looking at the attachment in vi showed that it's
a copy of the Hybris worm.

This might be a useful rule to add just before the Sanitizer call:

* ^Content-type: multipart/mixed;
* ! ^To:
* ! ^Subject:
  :0 B
  * ^Content-type: application/octet-stream;
  * name=.*\.EXE

Untested and subject to refinement. Comments?
