Microsoft disrupts botnet that generated $2.7M per month for operators: On Thursday, Microsofts Digital Crimes Unit, the legal and technical team that has driven the takedown of botnets such as Bamital and Nitol during the past year, announced that it has moved with Europol, industry partners, and the FBI to disrupt yet another search fraud botnet. The ZeroAccess botnet, also known as ZAccess or Siref, has taken over approximately 2 million PCs worldwide; Microsoft estimates that it has cost search engine advertisers on Google, Bing, and Yahoo over $2.7 million each month.
