Cyber warfare has been taken to a new, hard rockin' level.
According to one security expert, a computer virus has attacked computer systems in Iran and forced them to play heavy metal, at full volume, during the middle of the night.
The computer worm reportedly compromises the machines, and makes them repeat the track 'Thunderstruck' by AC/DC, ad nauseum.
The unconfirmed report, picked up by Gawker, comes from Mikko Hypponen, who is a researcher at the Finnish security company F-Secure.
He said that his team received several emails from Iran's Atomic Energy Organisation which claimed the AC/DC assault was in progress.
The emails said the worm had also shut down automatic systems and other hardware, as well as playing the hard-rock anthem.
"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," the email read.
"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."
The attack type - Metasploit - is a cheap, open-source form of malware, indicating many different groups, governments or individuals could potentially be behind it.
The reported attack comes just weeks after the discovery of Flame, the most complex of its kind in history.
The malware, which is suspected to have been developed and released by the United States, was able to download data, record keystrokes, control nearby phones with Bluetooth and map locations with WiFi signals, and cost less than $10m to develop.
