Back to the future - Moonlight Maze
Thomas Rid of King's College London presents the previously untold story of MOONLIGHT MAZE, the first known state-on-state computer espionage campaign in history. A detailed account is in the last chapter of his book RISE OF THE MACHINES, out in the summer of 2016, http://amzn.to/1qGVOGX
APT, a bit of jargon Thomas uses to open the talk, stands for "Advanced Persistent Threat," a common shorthand for espionage campaign.
