Duqu - is a 'son of Stuxnet'?
A research lab has discovered on computers in Europe a worm very similar to Stuxnet, according to a blog posted Tuesday by the IT security provider Symantec.
Researchers at the lab, which Symantec did not identify, named the new worm Duqu [dyü-kyü] because it creates files with the file-name prefix ~DQ. It shares a great deal of code with Stuxnet; however, the payload is completely different, Symantec researchers say.
