Iran denies its nuclear computer systems hit by new virus
Computers at two Iranian facilities were reportedly shut down by the virus, which also played loud rock music by AC/DC on the scientists' workstations.
Iran on Wednesday denied reports that its nuclear program's systems had been hit with a new cyber virus which shut down computer functions at two facilities - and played music by AC/DC at loud volume.
"Who seriously believes such a story? It is baseless and there has never been such a thing," Chief of Iran's Atomic Energy Organization (AEOI), Fereydoun Abbasi, told ISNA news agency.
The internet security website F-Secure said last week that it was informed of the cyber-attack by a scientist working at the AEOI, who sent them an email detailing the breach.
According to the scientist, the song Thunderstruck by Australian rock band AC/DC played randomly on several of the workstations during the middle of the night, with the volume on full.
The computer systems of the AEOI and related facilities, as well as some ministries, have previously been attacked by computer worms.
Iran has confirmed some of the cyber-attacks, but played down any damage.
In 2010 some 30,000 Iranian computers were infected with the sophisticated Stuxnet worm, which appeared to target computers connected to uranium-enriching centrifuges at nuclear sites.
Computer experts have speculated that the worm was developed by either Israel or the United States to derail Iran's disputed nuclear programs.
