DarkReading has a nice little featurette on the three largest botnets online — Storm (230,000 members per 24h period), Rbot (40,000), and Bobax (24,000), along with a sketchy report of a new humongous “P2P botnet” in the offing:
“We’re investigating a new peer-to-peer botnet that may wind up rivaling Storm in size and sophistication,” says Tripp Cox, vice president of engineering for startup Damballa, which tracks botnet command and control infrastructures. “We can’t say much more about it, but we can tell it’s distinct from Storm.”
