IRAN has been forced to take emergency action to protect its main oil terminal and other parts of its energy infrastructure after they came under a fresh wave of cyber attacks.
Reports on semi-official news agencies said that the oil terminal, on Kharg Island near the neck of the Persian Gulf, the central oil ministry and the main national oil company, as well as other linked companies, had all been targeted by a computer worm.
A deputy oil minister said it had not been determined whether the attack came from inside or outside the country.
Israel has been assumed to be responsible for several cyber assaults on Iran's key infrastructure. Most notably, Stuxnet, a sophisticated computer worm, infected Iran's nuclear program in 2010.
