In an address to a government-sponsored nuclear disarmament conference in Tehran on Monday, Ali Bagheri, the deputy director of Iran’s national security council, called on IAEA to open an investigation on the Stuxnet attack on the country’s nuclear facilities and the people behind the attack. Bagheri called the attackers “nuclear terrorists.” [Xinhua, 14 June].
Bagheri’s request was in effect the highest-level official announcement that the Stuxnet worm had infected the computers at Iran’s nuclear facilities. Iran’s Ministry of Foreign Affairs had previously denied reports that Stuxnet had affected the nuclear computer systems. The computer worm is specifically written to attack Windows-based SCADA systems which are used to control and monitor industrial processes, including those used in nuclear facilities.
