Waledac Botnet Now Completely Crippled, Experts Say
Found on Thread Post on Monday, 15 March 2010
One researcher said that Waledac now seems to be abandoned. "It looks crippled, if not dead," said Jose Nazario, a senior security researcher at Arbor Networks.
Waledac was not nearly the largest botnet in operation, nor was it even one of the top spam-producing botnets. It numbered somewhere fewer than 100,000 infected PCs.
The plan, which involved working with law enforcement and ISPs to take down nearly 300 .com domains involved in the botnet as well as disrupting the communications among the bots, appears to have worked as designed.
I wouldn't bet on it. Sometimes malware has nifty little pieces of code which could let it raise back from the dead. If it stays down, however, it's better.
