I'd be inclined to agree with you, Jose. I suspect this is something new
that's been "distributed" through a bot network of already compromised
machines (Agobot/Gaobot). I'm seeing *some* correlation between hosts
"poking" me on 3217 and 6129 (Agobot for sure) and 5000, but not on the
other ports.

Of course with the cut and paste worms that are coming out these days, who
can say what it really might be?
