Is there any particular pattern to the messages themselves? I'm thinking subject(s), particular headers, techniques for evading detection / confusing Bayesian filters, etc.?

Does anyone know if there's a worm out in the wild currently
doing this? I've confirmed with some of my collegues that other
ISPs are also experiencing this.

I'm interested in finding specific netblocks but the spam seems
to be coming from everywhere.
