Iran says its defence computer systems have been infected with another “supervirus” known to be similar to one which severely damaged its nuclear programme last year.
Anti-virus experts last month identified a virus called “Duqu” that they said shared properties with the now famous “Stuxnet” worm, which spread across the world but is thought to have been successfully targeted at the nuclear programme’s centrifuges, the devices that enrich uranium to create nuclear fuel.
It was not clear on Monday from the Iranian statement whether Duqu had also struck nuclear facilities, but it was the first admission of damage.
“We are in the initial phase of fighting the Duqu virus,” Gholamreza Jalali, the head of Iran’s civil defence programme, said. “The final report which says which organisations the virus has spread to and what its impacts are has not been completed yet.
“All the organisations and centres that could be susceptible to being contaminated are being controlled.”
