Israel and the US have been identified as the creators of the highly sophisticated Flame malware that was found to have been targeting Iranian computer systems, according to reports.
The Washington Post claims that sources with knowledge of the work said the National Security Agency (NSA), the CIA and the Israeli military were all involved in the creation of the malware, which was first uncovered in May.
The Post also reported that a high-ranking US intelligence official revealed that efforts against Iran's computer systems are still ongoing.
"This is about preparing the battlefield for another type of covert action. Cyber-collection against the Iranian programme is way further down the road than this," the official was quoted as saying.
Unsurprisingly the CIA, the NSA and the Office of the Director of National Intelligence, as well as the Israeli Embassy in Washington, all declined to comment on the claims when contacted by The Washington Post.
Nevertheless, the revelations back-up earlier reports that president Obama had backed covert US plans to create and launch Stuxnet against Iran in an effort to cripple the nation's nuclear development plans.
Recent reports also showed that Flame and Stuxnet had similar code components, suggesting close involvement between the two projects, again giving credence to the sources' claims.
