Koobface server taken down
A UK internet service provider (ISP) has taken the Koobface social networking botnet Command-and-Control server off-line after security specialists from the SecDev Group informed the UK investigative authorities about the server. While this will temporarily obstruct the botnet, it doesn't mean that the individuals behind Koobface have been neutralised. It's probably only a matter of time until the infected computers are redirected to a new server.
