GCHQ intel used to develop Stuxnet, claims new documentary

The super worm known as Stuxnet was but a cog in an active US war program in which hundreds of thousands of network implants and backdoors in Iran networks were actively maintained to facilitate a devastating barrage of hacking attacks, a documentary claims.

Zero Days, due to screen at the Berlin Film Festival today, claims that Stuxnet was just one part of an operation called "Olympic Games" that is itself part of a wider effort dubbed "Nitro Zeus" that involves hundreds of US defence personnel.

Nitro Zeus may also involve Israel, the film alleges. Reports from those who've seen or been briefed on the film suggest it alleges that Stuxnet's authors attempted to keep the program covert by restricting the malware to infect only Iranian machines.
