Russia blames US and Israel for Stuxnet worm

Russia has for the first time laid the blame for the Stuxnet worm at the door of the US and Israel, describing it as "the only proven case of actual cyber-warfare."

In translated comments reported by the AFP agency, foreign ministry security department chief Ilya Rogachyov was blunt about the origins of a piece of malware that has mystified experts since first appearing in June 2010.

"Experts believe that traces of this lead back to the actions of Israel and the United States," he said. "We are seeing attempts of cyberspace being used by some states to act against others [and] of it being used for political-military purposes," he added.
