The Stuxnet worm is one of the most sophisticated bits of digital malware security researchers have come across in a long time. Now, those researchers want to know where it came from. Was Stuxnet the product of a den of hackers working on their own accord, or did a national government somewhere in the world have a hand in its creation? “Given the sophistication and organization behind it, we highly suspect it has nation-state involvement rather than being a tool for competitive intelligence,” said Kaspersky Lab’s Roel Schouwenberg.
