The attack shut down the Natanz and Fordow nuclear facilities and caused infected computers to play AC/DC’s “Thunderstruck” at maximum volume — over and over again.
An Iranian scientist apparently contacted F-Secure, a Finnish cyber security site, and offered this explanation of the attack:
I am writing you to inform you that our nuclear program has once again been compromised and attacked by a new worm with exploits which have shut down our automation network at Natanz and another facility Fordo near Qom.
According to the email our cyber experts sent to our teams, they believe a hacker tool Metasploit was used. The hackers had access to our VPN. The automation network and Siemens hardware were attacked and shut down. I only know very little about these cyber issues as I am scientist not a computer expert.
There was also some music playing randomly on several of the workstations during the middle of the night with the volume maxed out. I believe it was playing ‘Thunderstruck’ by AC/DC.
No word on who is responsible for the attack. One possibility: Tony Stark. The guy’s smart enough to design a worm, and the song is featured prominently on the “Iron Man 2″ soundtrack. I’d be looking at Jon Favreau, too.
