Iran denies hacking into American banks

DUBAI — Iran denied its hackers attacked American banks, the semi-official Fars news agency reported on Sunday, following reports that American lenders were targeted. 

The hacking of websites and corporate networks at Bank of America, JPMorgan Chase & Co and Citigroup began in late 2011 and escalated this year, people familiar with the situation told Reuters.

"We officially announce that we haven't had any attacks," Head of Iran's civil defence agency Gholam Reza Jalali told Fars, when asked about the report.

National security officials told NBC News earlier this week that the continuing cyber attacks last week that slowed the websites of JPMorgan Chase and Bank of America were being carried out by the government of Iran. One of those sources said the claim by hackers that the attacks were prompted by the online video mocking the Prophet Muhammad was just a cover story.

The attack was described by one source, a former U.S. official familiar with the attacks, to NBC News, as being "significant and ongoing" and looking to cause "functional and significant damage." Also, one source suggested the attacks were in response to U.S. sanctions on Iranian banks.

Reuters reported the hackers targeted JPMorgan Chase, Bank of America and CItigroup in retaliation for their enforcement of Western economic sanctions against Iran's disputed nuclear program.

Iran says the program is aimed at generating electricity and not, as the United States, Israel and others allege, at making nuclear weapons. A senior Iranian lawmaker accused the head of the United Nations nuclear watchdog on Sunday of passing confidential information about Iran's nuclear activities to Israel.

The Islamic state has beefed up its cyber capabilities after the nuclear program came under attack in 2010 by the Stuxnet computer worm which caused centrifuges to fail at its main enrichment facility.

Tehran accused the United States and Israel of deploying Stuxnet.

Intelligence Minister Heydar Moslehi said in June that Iran had detected a planned "massive cyber attack" against its nuclear facilities, blaming the United States, Israel and Britain.

Jalali said Stuxnet was used against Iran to delay the country's nuclear activities.

"But we see that our activities are successfully continuing ... Our nuclear systems are now immune to such things," Jalali said, according to Fars.

Security experts say Iran's cyber capabilities are not as sophisticated as those of China, Russia, the United States or many of its Western allies.
