alphadogg writes: The notorious malware known as the Conficker worm still infects computers, a sort of wild horse with no rider, but investigators appear no closer to finding its creator. Also known as "Downandup," Conficker was discovered in November 2008, exploiting a vulnerability in Windows XP that allowed remote file execution when file-sharing was enabled. Microsoft patched it a month later. At its peak, Conficker infected upwards of 7 million computers, and Microsoft still ranks Conficker as the second-most prevalent malware family on domain-joined computers. Security researchers with the Conficker Working Group along with vendors including Microsoft successfully cut off the Conficker's operators from the botnet, but the group is still working to try to find Conficker's master. The problem is that botnet operators have stayed away from Conficker and not tried to reclaim it, a welcome development but one that leaves researchers with a lack of fresh electronic leads. "Well, we sort of won in that regard," , said Jose Nazario, a malware researcher. "On the other hand, if they're not interacting with it, there's no more evidence coming in."
