Microsoft Digital Crimes Unit (DCU), working together with the US Federal law enforcement units has brought down Rustock, the world’s largest email spam network.

Rustock, a botnet, that controlled around 2 million zombie machines worldwide, was sending out up to 30 million spam email messages each day into cyberspace.

no-spamRustock was taken down piece by piece – the master controllers (botnet controllers that sent out commands to compromized ‘zombie’ machines) were identified. Microsoft, working together with the US Marshall Service, seized some of these machines in the US for analysis and collaborated with the Netherlands police to disable some of the controllers outside the US.

Microsoft then worked with service providers to black hole IP addresses that were being used to control the botnet, and with the Chinese CN-CERT to block registration of domains that could be used for these purposes.

Microsoft provides the best anti-spam solution available in the market today, and also provides a variety of best-in-class unified threat management, rights management, secure remote access and anti-malware solutions.
