"An electronic war has been launched against Iran", Mahmoud Liayi, head of the information technology council at the ministry of industries, told the state-run Iran Daily newspaper. This, in response to reports that a sophisticated computer worm had infected the personal computers of staff at the country's first nuclear power station, the Bushehr plant, due to come on line in the coming weeks. Officials claim that the operating system at the plant has been unaffected by the Stuxnet worm, so sophisticated that it is believed to be the work of "a nation state".
Stuxnet targets systems made by the German company Siemens, these systems are typically used to manage water supplies, oil rigs, power plants and other utilities. The Iranians claim that computers operating on some 30,000 IP addresses within the country have been infected.
Western nations fears Iran's goal is to build nuclear weapons while Iranian officials says its programme is aimed solely at peaceful energy use.
