Azerbaijan, Baku, Feb.14 / Trend D. Khatinoglu/
Iranian passive defense system director Gholam-Reza Jalali said that the country's nuclear facilities are immune to cyber attacks and Iran enjoys enough science to defend them against threats.
According to IRNA, Jalali added that all nuclear activities in Iran are under full supervision. It has not been reported about any clue of cyber attack against our facilities yet.
"We have got enough experience to neutralize virus attacks after parrying the Stuxnet and today, we are fully prepared to neutralize other viruses including Stars and Duqu," he said.
He added that Duqu virus made an attempt to spy and get information from Iran's industrial sector, but it couldn't damage any industrial machines' activities.
Last year Iran said its defence computer systems have been infected with a ''supervirus'' similar to the one believed to have been created by Israel that severely damaged Tehran's nuclear program last year.
Anti-virus experts have identified a virus called "Duqu" that they say shares properties with the "Stuxnet" worm apparently created by Mossad, the Israeli security service. It was thought to have targeted the nuclear program's centrifuges, the devices that enrich uranium to create nuclear fuel.
It was not clear from the Iranian statement whether Duqu had also struck nuclear facilities, but it was Iran's first admission of damage.
The "Stuxnet" virus altered the speed at which the enrichment centrifuges spun until they were out of control. It was so sophisticated that experts said it must have been the work of an advanced, probably national, sabotage program. Duqu operates differently, though using some of the same code to infiltrate computers, sending back information to its handlers rather than breaking down systems. The virus was spread through an infected Microsoft Word document.
Symantec, the computer security firm, which has led investigations into Stuxnet and Duqu, said the new virus seemed to be intended to gain remote access to computer systems.
''The authors had access to the Stuxnet source code,'' Symantec said. ''The attackers are looking for information such as design documents that could help mount an attack on an industrial control facility. Duqu is essentially the precursor to a Stuxnet-like attack.''
