Researchers at Symantec have found a newly compiled driver for Duqu, leading to speculation that the attackers are still tweaking and modifying their original work. Researchers say that the number of known victims of Duqu is quite small, perhaps fewer than 50. Researchers spent a lot of time analyzing and poring over the drivers and the individual components of the malware and think that they have a pretty good handle on the way that the malware works now. But that doesn’t mean that it s fully understood yet.
