Collaboration Aids in Botnet Takedown: Microsoft, Law Enforcement, Others target ZeroAccess botnet. Botnet, also known as Sirefef, targets major search engines and browsers, including Google, Bing and Yahoo. Microsoft shuttered 18 European information providers and blocked traffic from American Internet service providers to those illicit European sites. ZeroAccess is the first botnet action taken by Microsoft since the company unveiled its new Microsoft Cybercrime Center on Nov. 14. The botnet, it says, costs online advertisers $2.7 million each month in lost revenues.”]
