July 25, 2012. Iran's nuclear facilities have suffered a cyber attack that shut down computers and played music from the rock band AC/DC, the F-Secure Security Labs website said. A new worm targeted Iran's nuclear program, closing down the"automation network" at the Natanz and Fordo facilities, the Internet security site reported, citing an e-mail it said was sent by a scientist inside Iran's Atomic Energy Organization. The virus also prompted several of the computers on site to play the song"Thunderstruck" by AC/DC at full volume in the middle of the night, according to the e-mail, part of which is published in English on the website.
