Atomic Energy Organization of Iran (AEOI) Chief Ali Akbar Salehi said Wednesday that no computer worm Penetrated main computer system of Bushehr nuclear facility, the ISNA news agency reported.
The Stuxnet, a computer worm that is viewed as potentially the most dangerous piece of computer malware discovered, has targeted industrial computers in Iran, the Mehr news agency reported earlier.
The complex worm recognizes a specific facility's control network and then destroys it.
"The virus has not reached the main system and it was only seen in some personal laptops of Bushehr complex staff, but required measures were taken," Salehi said.
Concerning some western media propaganda on virus in Bushehr plant's computer systems, he said, "we have started protective measures for computers since last year and we intensified them two months ago to prevent any virus."
Bushehr nuclear power plant began to be built by the German Kraftwerk Union concern in 1974, but in 1980 it terminated the contract because of Western German government's accession to the U.S. embargo on supplying equipment to Iran. Since the 1990's, construction of the power plant has been carried out by the Russian specialists. To control the nuclear power plant Russia and Iran have formed a joint venture. After two or three years, the station will almost completely come under the control of Iran, yet it remains under Russia's control.
