Hackers Who Breached Google Made Earlier Attacks, Expert Says

The hackers behind a breach of Google Gmail accounts mounted similar attacks on Fortune 100 companies for at least the past year and a half, said a security expert who examined the incidents. Investigators have created profiles of the hackers that show they have been involved in cyber attacks on large defense, financial and energy companies, said the person, who asked to remain anonymous. The person declined to name the firms. The security expert couldn't confirm a story by the New York Times that said the attacks on Google e-mail accounts originated at two Chinese educational institutions.
