Experts take down Grum spam botnet, world’s third largest

Personal computer-security industry experts took down the planet’s third-largest botnet, which they say was accountable for 18 percent with the world’s spam.

Command-and-control servers in Panama as well as the Netherlands pumping out as much as 18 billion spam messages every day towards the Grum botnet ended up taken decrease Tuesday, but the botnet’s architects setup new servers in Russia afterwards inside day time, according to A whole new York Periods report. California-centered safety company FireEye and U.K.-based spam-tracking services SpamHaus traced the spam back to servers in Russia and worked with neighborhood ISPs to shut lower the servers, which ran networks of contaminated devices referred to as botnets.
