“Something remarkable happened a few months ago. Bernard Barbier, the former head of signals intelligence (SIGINT) between 2006 and 2014 at France’s foreign intelligence agency (DGSE), gave a speech at one of France’s top engineering schools in which he reflected on his career and imparted some of his wisdom to students. He also said some things that he probably shouldn’t have, like confirming that France was behind the Animal Farm advanced persistent threat, commenting on the SIGINT capabilities of European allies, and reacting to the revelation that the U.S. National Security Agency (NSA) had compromised the networks of the French presidency.”
