Iran denies being 'thunderstruck' by hackers

Iran is denying claims that malware had managed to infect its nuclear facilities.

Iran has denied claims that its nuclear facilities had been broken into and forced to play AC/DC's "Thunderstruck".

Atomic Energy Organisation of Iran (AEOI) chief Fereydoun Abbasi responded to reports that broke last week of two nuclear facilities that were said to have been attacked by a cyber virus that shut down key functions and blasted rock music from workstations at night.

In a statement to the Iranian Students' News Agency, Abbasi dismissed the claims, saying that the reports were false, but did not explain the email sent from an AEOI scientist to F-Secure, which first alleged that there had been a breach.

At the time, F-Secure chief research officer Mikko Hypponen said that F-Secure was unable to confirm any of the details, but did confirm that the email had been sent from within AEOI's network.

Iran's official statements over its nuclear facilities have proven to be highly unreliable in the past, with Stuxnet a prime example. The country's officials initially stated that Stuxnet had caused no damage at Natanz , but later changed its position to state that a small leak had caused issues, before finally admitting that Stuxnet had affected the centrifuges used in the nuclear facility.

At the time of writing, AEOI's website also appeared to be down, although this may be unrelated to the alleged attack.
