Tellingly, the FBI's press release says that the bureau's conclusion is only based "in part" on these clues. This leaves open the possibility that the government has classified evidence that North Korea is behind the attack.
I am surprised that the article doesn't end here. Other press reports have highlighted that there is classified evidence that has not been disclosed, and it seems odd to me that Schneier would play this aspect down in a story involving cyberattacks, North Korea, the FBI and the US intelligence community.
