Microsoft Offers Reward for Information on Rustock Botnet

In a further move against international cyber criminals, Microsoft has offered a reward of $250,000.00 reward for information that results in the identification, arrest and criminal conviction of those responsible for controlling the notorious Rustock bot-net.

Microsoft says that IP address infections of Rustock have reduced by more than 50% worldwide since the company took action in March. Microsoft took the infamous Rustock botnet down earlier this year alongside U.S. enforcement agents, and claims that it remains dead.

The Rustock botnet was the largest source of spam in the world, consisting of around 150,000 machines sending around 30 billion spam messages a day. The take down was part of Microsoft’s fight against illegal botnets, designed to stop the spread of malware and spam mail.

Anyone with information on the Rustock botnet or its operators should contact Microsoft at
