Crashing the server that sent out 18 billion spam emails every day
Computer security experts say that every day there are 18 billion spam emails spread by the world's third largest Botnet server Grum, accounting for about 18% of computer spam worldwide.
Initially, the Grum Botnets were operating from servers in Panama and the Netherlands, sending up to 18 billion spam messages per day, but after being shut down on July 17, they were re-established on new servers in Russia.
California-based security firm FireEye and the UK's Spam Monitoring Service are now tracking spam coming from servers in Russia and are working with local internet service providers to shut down servers running the botnet.

The tech community is also stepping up efforts to control botnets, although this move is late in the tech forums. Microsoft in particular is very interested and asked the court to intervene to seize the servers, control and paralyze the computer network activities of Waledac, Rustock and Kelihos.
Previously in March 2011, the Rustock botnet was also removed, cutting the volume of spam worldwide by one-third. At its peak, this notorious botnet alone sent 44 billion spam messages per day, equivalent to more than 47% of all spam.
In the case of the Grum botnet above, some cyber experts are predicting that it may be launching a completely new campaign and infecting hundreds of thousands of new computers. Cyber security experts are planning to build a Grum attack software to cripple the server and stop the spam from spreading.
It is known that botnet refers to a network of computers using distributed computing software, a collection of software robots or bots that operate autonomously. When controlling the botnet, it is possible to spread many different programs and penetrate computers.
