Gathering Storm Superworm Poses Grave Threat to PC Nets
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.
Old style worms -- Sasser, Slammer, Nimda -- were written by hackers looking for fame. They spread as quickly as possible (Slammer infected 75,000 computers in 10 minutes) and garnered a lot of notice in the process. The onslaught made it easier for security experts to detect the attack, but required a quick response by antivirus companies, sysadmins and users hoping to contain it. Think of this type of worm as an infectious disease that shows immediate symptoms.
Worms like Storm are written by hackers looking for profit, and they're different. These worms spread more subtly, without making noise. Symptoms don't appear immediately, and an infected computer can sit dormant for a long time. If it were a disease, it would be more like syphilis, whose symptoms may be mild or disappear altogether, but which will eventually come back years later and eat your brain.
