Me thinks the congressman doth protest too much.
Based solely on an IP address they drew the conclusion that the attacker was actually Chinese. That, is pretty thin.
From Network World:
The Chinese Foreign Ministry has denied any connection to the attacks, according to reports. An FBI spokeswoman declined to comment on the matter late Thursday.
However, computer security experts said that the evidence that the two congressmen provided to back up their claims simply does not prove that the Chinese government, or even Chinese nationals, were involved.
“It’s so very hard to conclude that something came from someplace if all you’re going from is an IP address,” said Marcus Sachs, director of the SANS Internet Storm Center, a volunteer-run effort that tracks emerging computer threats. “Those of us who have done this for a living, we know that you can’t prove that it was a Chinese person on the keyboard if you have a Chinese IP address,” he said. “Without making some of the evidence public … you leave everybody else guessing.”
And the beat goes on.
