Botnet responsible for 18 percent of worlds spam taken down

Security firm FireEye, spam tracker SpamHaus, and local ISPs have shut down a botnet that they claim was responsible for 18 percent of the world's spam.

Security firm FireEye, spam tracker SpamHaus, and local ISPs have shut down a botnet that they claim was responsible for 18 percent of the world's spam.

 
The botnet, called Grum, had control servers located in Panama, Russia and Ukraine, with controllers of the network redirecting to secondary servers as the net closed in on them. 
 
Hunting down the servers in Ukraine was particularly challenging, given its prior reputation as a “safe haven” for such operations, but FireEye pressured ISPs to suspend the servers there, which will serve as a stark warning to spammers who think that relocation is an option.

As many as 20,000 computers are part of the botnet, but without the command and control servers they are ineffective.
 
Spam, the bane of the internet, may become a thing of the past as more botnets are shut down across the world. Bredolab, a botnet responsible for a whopping three billion spam emails every day, was shut down by Dutch police in 2010, and its mastermind, Georgiy Avanesov, was jailed earlier this year
 
“Grum's takedown resulted from the efforts of many individuals,” said Atif Mushtaq, security researcher at FireEye. “This collaboration is sending a strong message to all the spammers: Stop sending us spam. We don't need your cheap Viagra or fake Rolex.”
