Claim: In June 2010, Iran was the victim of a cyber-attack when its nuclear facility in Natanz was infiltrated by the cyber-worm 'Stuxnet' but crowdsourced solutions to the worm and is now better positioned in terms of cyber warfare technology.
Evidence: Between 2007–2010 Natanz nuclear power plant was hit by a sophisticated cyber attack that has been alleged to have been carried out in an operation called Olympic Games by a coalition of German, French, British, American, Dutch and Israeli intelligence organizations. The attack used a Stuxnet worm which hampered the operation of plant's centrifuges and caused damage to them over time. In response to the infection, Iran assembled a team to combat it.
