Storm more powerful than supercomputers

The Storm worm botnet has grown so massive and far-reaching that it easily overpowers the world's top supercomputers.

"In terms of power, the botnet utterly blows the supercomputers away," said Matt Sergeant, chief anti-spam technologist with MessageLabs, in an interview. "If you add up all 500 of the top supercomputers, it blows them all away with just 2 million of its machines. It's very frightening that criminals have access to that much computing power, but there's not much we can do about it."

Sergeant said researchers at MessageLabs see about 2 million different computers in the botnet sending out spam on any given day, and he adds that he estimates the botnet generally is operating at about 10 percent of capacity.

"We've seen spikes where the owner is experimenting with something and those spikes are usually five to 10 times what we normally see," he said, noting he suspects the botnet could be as large as 50 million computers. "That means they can turn on the taps whenever they want to."

The botnet actually is attacking computers that are trying to weed it out. It's set up to launch a distributed denial-of-service attack against any computer that is scanning a network for vulnerabilities or malware.
