A geographical distribution of computers hit by Stuxnet, which Microsoft produced in July, found Iran to be the apparent epicenter of the Stuxnet infections. That suggests that any enemy of Iran with advanced cyber war capability might be involved, Langner says. The US is acknowledged to have that ability, and Israel is also reported to have a formidable offensive cyber-war-fighting capability.

Cyber-warfare has already been waged by the Russians against Estonia in '07. Other cyber attacks have been accomplished as early as '82. Iran boasts they have the second largest cyber-army in the world.
