This is what I'm seeing as well. A system that fingerprints as a Win2K
box that is vertically scanning my network for TCP/3389. Based on the
source ports and IP ID's its *very* busy scanning other networks at the
I'm guessing this is some kind of worm or something that breaks in via
3389 and then tries to propagate out over the same port.
I'm on the road right now, anyone want to setup Netcat to do a capture
so we can see what they are doing?
