Israel's Preemptive Strike?
Stuxnet shuts down Iran's nuclear facilities
Iran's nuclear program has suffered a recent setback, with major technical problems forcing the temporary shutdown of thousands of centrifuges enriching uranium, diplomats told The Associated Press on Monday.
The diplomats said they had no specifics on the nature of the problem that in recent months led Iranian experts to briefly power down the machines they use for enrichment — a nuclear technology that has both civilian and military uses.
But suspicions focused on the Stuxnet worm, the computer virus thought to be aimed at Iran's nuclear program, which experts last week identified as being calibrated to destroy centrifuges by sending them spinning out of control.
North Korea might want to remove the USB ports from any computers inside their uranium enrichment facility.
