Microsoft Takes Down A Large Botnet Called Rustock

Microsoft has taken down a very large and complex botnet, called Rustock. It has been estimated that this botnet consisted of approximately one million infected computers and is known to send billions of spam mails on a daily basis, including fake Microsoft lottery scams and fake prescription drugs.

Rustock was one of the world’s largest spambots, capable of sending 30 Billion spam e-mails per day. Researchers have seen a single Rustock-infected computer send 7,500 spam emails in 45 minutes, as well as advertising counterfeit pharmaceuticals.
