Iran earlier confirmed that, deep Stuxnet affect many systems in the country, including non-critical systems in a nuclear reactor. But this is the first time they said, Stuxnet also affect the centrifuges.

Now security researchers believe that, at least 2 Stuxnet goal: a centrifuge (as he refers to Ahmadinejad ) and other types of industrial systems as targets for attack code of the worm 417 . Ralph Langner, Stuxnet researchers believe that this goal could be the 2nd turbines in nuclear reactors for Iran's Bushehr. Stuxnet depth unusual in that it found the system very specific industries and then trying to disrupt their activities. Currently this worm is designed to slow and then speed centrifuges, which can damage the uranium is refined or damaged equipment.
