“U.S. officials said Iran hacked unclassified Navy computers in recent weeks in an escalation of Iranian cyberintrusions targeting the U.S. military.

The allegations, coming as the Obama administration ramps up talks with Iran over its nuclear program, show the depth and complexity of long-standing tensions between Washington and Tehran.

The U.S. officials said the attacks were carried out by hackers working for Iran’s government or by a group acting with the approval of Iranian leaders. The most recent incident came last week, before a security upgrade, the officials said. Iranian officials didn’t respond to requests for comment.”
