Crashed server sending 18 billion spam messages per day
Computer security experts say that every day, 18 billion spam messages are sent out 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-infected network.

The tech community is also stepping up efforts to control botnets, although this move is late in the tech forums. Microsoft is particularly interested and has asked the court to take over the servers, control and paralyze the computer network operations of Waledac, Rustock and Kelihos.
Previously in March 2011, the Rustock botnet was also taken down, 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 paralyze servers and stop spam distribution.
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.
