W32.Witty.Worm utilizes a Vulnerability in ICQ Parsing by ISS Products. The worm sends itself out to multiple IP addresses on source port 4000/UDP and a random destination port. The worm is a memory-only based threat and does not create files on the system.

The worm has a payload of overwriting random sectors of a random hard disk.
