"[I]f Garrett is to be believed, then the FBI may have been fooled by a simple prank"

If the FBI published a security bulletin based on anonymous and unauthenticated internet posts, that’s going to make it more difficult for people to believe its other claims.

Along with the threat against CNN, the FBI also mentioned another PasteBin post that mocked the bureau’s own investigation. If the prankster is to be believed, that second post could also be fake.

Some security experts have cast doubt on the FBI’s claim that North Korea was behind the hack of Sony Pictures. If the FBI has been fooled by an online prankster, that could make its claim that North Korea ordered the hack more difficult to believe.
