itwbennett writes "Ninety of the 249 Zeus command-and-control servers were knocked offline overnight when two ISPs, named Troyak and Group 3, were taken offline. Whoever was behind the takedown 'just decided to knock out a large area of cyber-crime, and this was probably one of the easiest ways to do it,' said Kevin Stevens, a researcher with SecureWorks. As with the McColo takedown of just over a year ago, Troyak's upstream providers seem to have knocked it off the Internet, Cisco said in a statement. 'The ISP was "De-peered,"' Cisco said. 'Troyak's upstream network providers effectively pulled the plug on Troyak's router, refusing to transmit its traffic.'"
