Later Iran get cyberattack again and paralyse their nuke system.
Attacks against Iran
In June 2010, Iran was the victim of a cyber-attack when its nuclear facility in Natanz was infiltrated by the cyber-worm 'Stuxnet'.[10] Reportedly a combined effort by the United States and Israel,[11] Stuxnet destroyed perhaps over 1,000 nuclear centrifuges and, according to a Business Insider article, "[set] Tehran's atomic programme back by at least two years."[12] The worm spread beyond the plant to allegedly infect over 60,000 computers, but the government of Iran indicates it caused no significant damage. Iran crowdsourced solutions to the worm and is purportedly now better positioned in terms of cyber warfare technology.[10] No government has claimed responsibility for the worm.[12]
