Video Clip Reveals Possible Chinese State-Sponsored Hack Attack

Solid proof regarding the origins of high-profile international cyberattacks is typically elusive. However, when Western interests are targeted, suspicion often turns to China -- whether rightfully or otherwise.

Those suspicions were again aroused recently, courtesy of government-controlled China Central Television.

CCT ran a 20-minute documentary called "Military Technology: Internet Storm Is Coming." The clip included a brief segment featuring a hacking tool that appears to be used to attack a U.S. website.

While the subjects of the segment speak about theory, the video footage shows Chinese government systems launching attacks against a U.S. target, according to Mikko Hypponen, chief research officer of anti-virus firm F-Secure. He called the situation "highly unusual."
