UDP port 4000 traffic: likely a new worm

Sat Mar 20 19:09:50 UTC 2004

Confirmed.  We had our first customer (colo) hit yesterday evening at 
20:43 PST.  Additionally, they experienced the hard drive corruption (which
was added to the ISC diary entry within the last several hours).  Traffic 
was 4000/udp.  Initial 90 Mbit/s peak which leveled out at a constant
60 Mbit/s before we took them off-line.
