The FBI disagrees with Your JoeDog. As of a few minutes ago, the Times published an article in which the FBI accuses North Korea of organizing the cyber attack on Sony Pictures.

Okay, what do they got?

The bureau said that there were significant “similarities in specific lines of code, encryption algorithms, data deletion methods, and compromised networks” to previous attacks by the North Koreans. It also said that there were classified elements of the evidence against the North that it could not reveal.

This is not unexpected. Cyber attackers around the world share code, tools and ideas. I wouldn’t be surprised if this toolkit contains signatures that match those used by the CIA, Iran, Israel or Anonymous.

What else do you got?

“The F.B.I. also observed significant overlap between the infrastructure used in this attack and other malicious cyberactivity the U.S. government has previously linked directly to North Korea,” the bureau said. “For example, the F.B.I. discovered that several Internet protocol addresses associated with known North Korean infrastructure communicated with I.P. addresses that were hardcoded into the data deletion malware used in this attack.”

The wording here is curious: “known North Korean infrastructure.” What does that mean? Are they in North Korea’s one known block of public IP addresses or are these Class C addresses the FBI has seen before? Kim Hak Uhr codes at a workstation with a 192.168.0.4 address so it must be North Korea!!1!1!

So we have a similarities of code, unknown IP addresses and evidence the FBI can’t reveal because s3cr37s! That’s pretty scant. I remain skeptical, very skeptical.
