The Obama administration has been focused on Iran because the attacks have given the Iranian government a way to retaliate for tightened economic sanctions against it, and for the American and Israeli program that aimed similar attacks, using a virus known as Stuxnet, on the Natanz nuclear enrichment plant.
In a letter to the editor of The Times, responding to a May 12 article that reported on the new attacks’ similarity to the Saudi Aramco episode, Alireza Miryousefi, the head of the press office of the Iranian mission to the United Nations, wrote that Iran “never engaged in such attacks against its Persian Gulf neighbors, with which Iran has maintained good neighborly relations.”
American officials have not offered any technical evidence to back up their assertions of Iranian authorship of the latest attacks, but they describe the recent campaign as different from most attacks against American companies — particularly those from China — which quietly siphon off intellectual property for competitive purposes.
The White House would not confirm that Iran was the source, but Laura Lucas, a spokeswoman for the National Security Council, said that “mitigating threats in cyberspace, whether theft of intellectual property or intrusions against our critical infrastructure” was a governmentwide initiative and that the United States would consider “all of the measures at its disposal — from diplomatic to law enforcement to economic — when determining how to protect our nation, allies, partners, and interests in cyberspace.” But Homeland Security was able to issue a broader warning because of an executive order, signed in February, promoting greater information sharing about such threats between the government and private companies that oversee the nation’s critical infrastructure. It said the government was “highly concerned about hostility against critical infrastructure organizations,” and included a link to a previous warning about Shamoon, the virus used in the Saudi Aramco attack last year.
Government officials also say Iran was the source of a separate continuing campaign of attacks on American financial institutions that began last September and has since taken dozens of American banks intermittently offline, costing millions of dollars.
