Threat-intelligence firm Norse says it has found evidence that six people were behind Sony hack. Norse: “We are very confident that this was not an attack master-minded by North Korea” Other evidence suggests that the attackers were not native Korean speakers, despite the FBI having attributed the hack to the government of North Korea.

A group that calls itself Guardians of Peace, or G.O.P., has claimed credit for hacking Sony.”]
