Gathering 'Storm' Superworm Poses Grave Threat to PC Nets

The Storm worm first appeared at the beginning of the year, hiding in e-mail attachments with the subject line: "230 dead as storm batters Europe." Those who opened the attachment became infected, their computers joining an ever-growing botnet. Although it's most commonly called a worm, Storm is really more: a worm, a Trojan horse and a bot all rolled into one. It's also the most successful example we have of a new breed of worm, and I've seen estimates that between 1 million and 50 million computers have been infected worldwide.
