Subject: Tracking SirCam

Trying to track the SirCam virus without looking at the body of the
message, we've found a way to track it via headers.

In the header of the message, everything looks dynamic, and so tracking it
seems to be hard. However, there is a slip -- the Date: header actaully
appears as 'date:'.

A cursory examination of thousands of emails from mailing lists, private
sources, and other sources shows that the only messages using the lower
case 'date:' for the header are sent by the SirCam virus.

This may help those of you who want to filter on headers and not on
message body.
