OperationsBefore its eventual takedown, the Waledac botnet consisted of an estimated 70,000-90,000 computers infected with the "Waledac" computer worm.[1] The botnet itself was capable of sending about 1.5 billion spam messages a day, or about 1% of the total global spam volume.[2][3] On February 25, 2010, Microsoft won a court order which resulted in the temporary cut-off of 277 domain names which were being used as command and control servers for the botnet, effectively crippling a large part of the botnet.[4] However, besides operating through command and control servers the Waledac worm is also capable of operating through peer-to-peer communication between the various botnet nodes, which means that the extent of the damage is difficult to measure.[5] Codenamed 'Operation b49', an investigation was conducted for some months which thereby yielded an end to the 'zombie' computers. More than a million 'zombie' computers were brought out of the garrison of the hackers but still infected.[6] In early September 2010, Microsoft was granted ownership of the 277 domains used by Waledac to broadcast spam email.[7] See also
