The war of words between the United States and Iran appears to be heating up in cyberspace. In recent weeks, the tension has grown palpable as the United States leads the drive to reimpose sanctions on Iran beginning Aug. 6. U.S. President Donald Trump and Secretary of State Mike Pompeo have traded heated threats with Iranian President Hassan Rouhani and Maj. Gen. Qassem Soleimani, the leader of the Islamic Revolutionary Guard Corps' Quds Force. Though both sides are certainly capable of direct physical attacks, conventional warfare is not in their immediate interests. Iran has embraced cyberattacks as part of its asymmetric response to its Middle Eastern rivals and the United States, and this latest round of belligerence will likely be played out through cyber actions.
