U.S. launched cyberattacks on Iranian military computers last week

WASHINGTON - U.S. military cyberforces launched a strike against Iranian military computer systems on Thursday as President Donald Trump backed away from plans for a more conventional military strike in response to Iran's downing of a U.S. surveillance drone, U.S. officials said Saturday. Two officials told The Associated Press that the strikes were conducted with approval from Trump. A third official confirmed the broad outlines of the strike. All spoke on condition of anonymity because they were not authorized to speak publicly about the operation. The cyberattacks -- a contingency plan developed over weeks amid escalating tensions -- disabled Iranian computer systems that controlled its rocket and missile launchers, the officials said.
