UDP port 4000 traffic: likely a new worm

Mon Mar 22 04:46:48 UTC 2004

The number of immediately vulnerable hosts was rapidly depleted by the
worm, given the launch was AFTER most business had shut down for the
weekend. I'll venture that Black Ice, a commercial security product, is
deployed much more widely on the corporate laptop than the home machine.

I expect to see more than a slight bump in those numbers come Monday AM.
