Never underestimate the usefulness of plausible deniability, one of the main advantages of cyber warfare. It doesn't even have to be cyber warfare. North Korea still denies that it was behind the 2010 sinking of the Cheonan, a South Korean naval vessel. Conspiracy theorists still dispute the conclusion of an international inquiry that North Korean torpedoes were to blame. It's quite useful from the North Korean regime's point of view to sow that seed of doubt in the mind of the international audience and to encourage mistrust of official narratives.
