Kelihos is a botnet that , at its peak , was post 4 billion spam substance a day . According to the security blog ThreatPost , the botnet was n’t so much shut down as it was “ sinkholed . ” The botnet is still operational , but it ’s 100 % command by Kaspersky Labs ( who , by the way , break down toreceive recognitionfrom Microsoft for their efforts ) . Botnets of course , function by infect computers of random the great unwashed with internet connections , then using those compromised motorcar to do their evilness bidding over a private peer - to - equal meshing . Kaspersky gained control of the botnet by start the automobile to talk to their servers more than the literal botnet servers .
This Monday , we started to propagate a exceptional match speech . Very soon , this computer address became the most predominant one in the botnet , leave in the bots talking to our automobile , and to our car only . expert call such an action sinkholing – bot transmit with a sinkhole instead of its real controller . At the same time , we distributed a particularly craft list of job servers to replace the original one with the address remark before and prevent the bot from request command . From this point on , the botnet could not be commanded anymore .
But here ’s the tricky part : since Kaspersky ca n’t keep out down each individual infected reckoner , they ca n’t shutdown the botnet . They conceive they could have the botnet push an update to every car that would remove the infection and closedown the web , but they say such a move is quite illegal . Oh well ! [ ThreatPost ]
