Israel Behind Stuxnet Attack on Iran?

I’m going to leave it to the cyberwar legal experts to discuss the legal issues, but regarding the recent Stuxnet worm that Iran reports infected particularly its nuclear program, the New York Times says …

Experts dissecting the computer worm suspected of being aimed at Iran’s nuclear program have determined that it was precisely calibrated in a way that could send nuclear centrifuges wildly out of control.

Their conclusion, while not definitive, begins to clear some of the fog around the Stuxnet worm, a malicious program detected earlier this year on computers, primarily in Iran but also India, Indonesia and other countries.

The paternity of the worm is still in dispute, but in recent weeks officials from Israel have broken into wide smiles when asked whether Israel was behind the attack, or knew who was. American officials have suggested it originated abroad.

The new forensic work narrows the range of targets and deciphers the worm’s plan of attack. Computer analysts say Stuxnet does its damage by making quick changes in the rotational speed of motors, shifting them rapidly up and down.
