Stuxnet may have destroyed 1,000 centrifuges at Natanz | Jerusalem Post

David Albright, president of the Institute for Science and International Security, told the Post that during a study of the Stuxnet code, he discovered that the virus caused the engines in Iran’s IR-1 centrifuges to increase and decrease their speed. The report cited an unnamed government official who claimed that Iran usually ran its motors at 1,007 cycles per second to prevent damage, while Stuxnet seemed to increase the motor speed to 1,064 cycles per second.
