Peter Yuryevich Levashov, the botnet’s alleged operator, was arrested last week in Spain. He is accused of infecting Windows PCs with malware to form a botnet, or a network of enslaved computers. Kelihos has enslaved hundreds of thousands of computers and distributed spam and malware to users across the globe. U.S. has taken action to dismantle the illegal operation, the Department of Justice said on Monday. The DOJ hasn’t said if others might have been involved in the operation, but the DOJ has obtained a court order to redirect internet traffic to a dummy server under the investigation’s control.”]
