President George W. Bush famously talked about the Axis of Evil, pointing to enemy regimes like North Korea, Iraq and Iran. America's strained relationships with those countries continues.
Yet, in recent months it has appeared that the U.S.'s relationship with Iran has been improving. In July, Iran agreed to new restrictions on its development of nuclear energy, which the White House says blocks its path to building nuclear weapons. Plus, just last week, Iran joined a multinational effort to end the civil war in Syria.
However, in Congress and elsewhere, there's a lingering distrust of Iran. As it turns out, with good reason. There has been a surge in cyberwarfare attacks from Iran that are targeting Obama Administration officials. These attacks are raising renewed concerns about the U.S.'s cyberdefense efforts.
White House officials say Iran has an army of hackers who've been trained by Russia. The White House this week confirmed that Iran's hackers have targeted Administration officials, including the State Department's Office of Iranian Affairs and its Bureau of Near Eastern Affairs.
They also suggested the attacks are linked to the recent arrest of Iranian-American businessman Siamak Namazi. Namazi had been an outspoken proponent of the countries' recent nuclear accord, saying the sanctions that the U.S. had imposed on the country hurt everyday Iranians, not the country's leaders.
