Biggest botnet takedown in history sees Rustock go offline

first_imgWhen e-mail providers like Google came on the scene the amount of spam in our inboxes fell, not because there was less of it about, but because more intelligent measures were being taken to identify and block it. Levels of spam circulating the Internet always seem to be on the increase and new measures required to block it, but this week those levels fell dramatically.The reason for the sudden fall was a coordinated attack on one of the most successful botnets out there called Rustock. Multiple servers used by the botnet were taken offline simultaneously on Wednesday crippling Rustock’s 26 command and control networks and therefore stopping them sending out around 30 billion spam messages every single day.AdChoices广告Those networks were thought to be controlling in the region of 815,000 Windows PCs around the world infected with Rustock’s rootkit and doing its dirty work. Unless those command networks can be brought back online, which nobody wants, those infected machines become useless to the spammers.Security experts are seeing this as a major breakthrough in cutting down on levels of spam. Rustock remained prevalent due to a number of tactics it used to remain undetected making it very difficult to shutdown. Unless you cut off all its heads at once it will come back, and this time it looks as though it may hopefully remain offline.While it is unknown who planned and coordinated this takedown of the botnet, everyone agrees that whoever did it certainly knew the botnet well and took measures to counteract any backup techniques Rustock used to re-establish itself and its connection with the infected Windows PCs.Read more at Krebs on Security (image via Wikipedia)last_img read more
