Iran admits cyber attack on N-project
Tehran, November 29, 2010
Enemies of Iran used computer code to make "limited" problems for centrifuges involved in uranium enrichment at some of its nuclear sites, President Mahmoud Ahmadinejad said.
"They succeeded in creating problems for a limited number of our centrifuges with the software they had installed in electronic parts," he told reporters at a media conference.
"They did a bad thing. Fortunately our experts discovered that and today they are not able (to do that) anymore," he said.
In September Iran said that the Stuxnet computer virus, that experts said may have been created by a state, did not affect Iran's nuclear plant or government systems but did hit computers of staff at the plant and Internet providers.
Stuxnet, a powerful example of the fastest-growing sort of computer bug -- customised malware written specifically to attack a precise target, has attracted publicity through a presumed link to Iran.
The Islamic Republic has been experiencing years of problems with equipment used in its uranium enrichment programme and Stuxnet may be one of the factors, former top UN nuclear inspections official Olli Heinonen said on November 20. - Reuters
