A former top-ranking Pentagon general is reportedly under investigation for leaking the information that publicly exposed a U.S. cyberwarfare operation against Iran. NBC News reports retired Marine General James “Hoss” Cartwright, the former vice chair of the Joint Chiefs of Staff, has been notified of a Justice Department probe into whether he leaked information to The New York Times on the computer virus known as Stuxnet. The United States used Stuxnet to sabotage the systems at Iran’s nuclear facilities, but in doing so accidentally set off a computer worm across the global Internet. Cartwright retired from the military in August 2011.
