The United States believes Iran was behind a major cyberattack on Saudi Arabia’s state oil company and a Qatari gas firm, a former US official who has worked on cybersecurity issues said.
In a major speech on cybersecurity on Thursday, Defense Secretary Leon Panetta issued a veiled warning to Tehran that Washington is ready to take pre-emptive action to protect US computer networks, the former official said.
US government agencies have concluded that Iran orchestrated the “shamoon” virus that disabled tens of thousands of computers at Saudi Aramco and struck Qatari natural gas firm RasGas as well, said James Lewis, who has worked for the State Department and other government agencies on national security and cyber issues.
American officials had “more than a suspicion” that Iran was to blame for the August attacks, that also possibly included recent denial of service attacks on some US banks, said Lewis, a senior fellow at the Center for Strategic and International Studies, a Washington think tank.
Lewis said he was not privy to the intelligence reports that backed up the assertion, but said it was implausible the Iranian government would not be aware of a major cyber operation coming from sources inside the country.
US government officials had concluded that Iran likely launched the attack in retaliation for US-led sanctions over its nuclear program and a cyber sabotage campaign reportedly backed by Washington, he said.
A senior administration official, who spoke on condition of anonymity, told AFP the cyber attack on the Gulf oil giants was believed to be carried out by a “state actor” and acknowledged that Iran would be a prime suspect.
In his speech on Thursday, Panetta referred to the “shamoon” virus for the first time publicly, saying it erased critical files on about 30,000 computers at Saudi Aramco, the world’s largest oil company.
He said the virus, which hit Qatar’s Rasgas a few days later, was “probably the most destructive attack that the private sector has seen to date.”
He also spoke of “foreign actors” probing sensitive US networks and cited denial of service attacks on some large US financial companies in recent weeks.
While he reiterated US concerns about cyber threats linked to Russia and China, Panetta said Iran was building up its digital capabilities.
In the same speech to business executives in New York, Panetta said the United States had improved its ability to track the origin of digital attacks and suggested the military stood ready to take pre-emptive action in cyberspace to protect vital networks.
Iran has advanced its digital warfare capacity faster than US officials had anticipated, Lewis said, though the attack on Saudi Aramco was relatively unsophisticated.
