TCP 1025 scanning worm?

["Richard Johnson" <rdump () river com>]

Starting at 11:38:12 UTC on July 17, we started seeing full-network port
scans looking for TCP port 1025.

The sources are all Windows boxes listening on TCP port 1025.  The ramp up
in volume from widely separated source IPs looks wormy.

Is this a targeted attack against my nets, or are others seeing this
scanning too?
