But in any case, when would a legitimate 'bounce' notification have an
attachment?

Because the clueless admin of the system generating the bounce has it
set up that way. Sobig's propagation was considerably aided by this
piece of stupidity, as the bounced messages went to the forged 'From'
addresses, resulting in Sobig being sent to even more people.
