Microsoft Disables Kelihos Botnet

Trailrunner7 writes with an excerpt from an article in Threatpost: "Continuing its legal assault on botnet operators and the hosting companies that the criminals use for their activities, Microsoft has announced new actions against a group of people it contends are responsible for the operation of the Kelihos botnet. The company has also helped to take down the botnet itself and says that Kelihos's operators were using it not only to send out spam and steal personal information but also for some more nefarious purposes."
