An Iranian official said that hackers attacked two government institutions this week, but details are scant.
The attacks took place on Monday and Tuesday, and some government bodies temporarily shut down their internet as a precaution, Reuters reported on Thursday.
Speaking to state television, Abolghasem Sadeghi of the government’s Information Technology Organization did not provide details on the targets or the hackers. He did describe the attacks as “large scale,” according to Reuters.
There was a series of mysterious explosions and fires in Iran over the summer, including at military facilities. In September, Iran said it found the people responsible for the July explosion at the Natanz nuclear facility, but the government did not say who they are.
The New York Times reported that an unnamed Middle Eastern intelligence official said Israel planted a bomb at Natanz at the time.
