[WSJ] Iran's powerful Revolutionary Guard military force hacked email and social-media accounts of Obama administration officials in recent weeks in attacks believed to be tied to the arrest in Tehran of an Iranian-American businessman, U.S. officials said.The Islamic Revolutionary Guard Corps, or IRGC, has routinely conducted cyber-warfare against American government agencies for years. But the U.S. officials said there has been a surge in such attacks coinciding with the arrest last month of Siamak Namazi, an energy industry executive and business consultant who has pushed for stronger U.S.-Iranian economic and diplomatic ties.
Obama administration personnel are among a larger group of people who have had their computer systems hacked in recent weeks, including journalists and academics, the officials said. Those attacked in the administration included officials working at the State Department's Office of Iranian Affairs and its Bureau of Near Eastern Affairs.
"U.S. officials were among many who were targeted by recent cyber-attacks," said an administration official, adding that the U.S. is still investigating possible links to the Namazi case. "U.S. officials believe some of the more recent attacks may be linked to reports of detained dual citizens and others."
