I find it amusing in a way that the New York Saddam Times touted this “revelation” that Israel tested the Stuxnet worm prior to its deployment in Iran’s nuclear facilities. That’s about as bad (but not quite) as the world’s worst-kept secret: that Israel has a nuclear arsenal.
Well, since it’s out there, let’s take a peek and see the details as to exactly what was affected:

In early 2008 the German company Siemens cooperated with one of the United States’ premier national laboratories, in Idaho, to identify the vulnerabilities of computer controllers that the company sells to operate industrial machinery around the world — and that American intelligence agencies have identified as key equipment in Iran’s enrichment facilities.

That’ll piss off الرئيس أوباما for sure….

Seimens says that program was part of routine efforts to secure its products against cyberattacks. Nonetheless, it gave the Idaho National Laboratory — which is part of the Energy Department, responsible for America’s nuclear arms — the chance to identify well-hidden holes in the Siemens systems that were exploited the next year by Stuxnet.
The worm itself now appears to have included two major components. One was designed to send Iran’s nuclear centrifuges spinning wildly out of control. Another seems right out of the movies: The computer program also secretly recorded what normal operations at the nuclear plant looked like, then played those readings back to plant operators, like a pre-recorded security tape in a bank heist, so that it would appear that everything was operating normally while the centrifuges were actually tearing themselves apart.

Pick your movie. And there are few things more satisfying than schadenfreude.
