"Despite having a self-termination date of September 10th, 2003 that crippled its aggressive emailing spreading routine, the massive volume of infection reports prior to the de-activation date easily secured Worm/Sobig.F as the top spot," said Steven Sundermeier, Vice President of Products and Services at Central Command, Inc.

According to Central Command's EVRT, the top new nuisance was Worm/Gibe.C. "Worm/Gibe.C was crafted to disguise itself as a cumulative security patch from Microsoft. The closely mirrored emails combined with the hot topic of patching vulnerable systems mislead users down the path of virus infection."
