There have been persistent whispers that the United States and Israel collaborated on the Stuxnet worm, which hit the computer systems of a nuclear plant in Iran a few years ago and was discovered in 2010. Earlier this month, spyware dubbed Flame was found on computers in Iran and elsewhere in the Middle East. Security experts have said Stuxnet and Flame have the same creators. Now the Washington Post reports, citing anonymous “Western officials,” that the U.S. and Israel were those creators; that Flame was created first; and that Flame and Stuxnet are part of a broader cyber-sabotage campaign against Iran. That campaign started under President George Bush and is continuing under President Barack Obama, according to a New York Times report earlier this month. (See Burning questions about Flame and cyberwar.) The Washington Post report describes Flame as “among the most sophisticated and subversive pieces of malware to be exposed to date” — a fake Microsoft software update that allows for a computer to be watched and controlled from afar.
