This certification provides an in-depth understanding of North Korea's cyber strategy, one of the most singular in the world. It explains how a poor and isolated regime, driven by Juche ideology and an obsession with survival, turned cyberspace into an asymmetric weapon and a source of revenue. The programme covers the organisation of its cyber force under the Reconnaissance General Bureau, destructive operations (DarkSeoul, Sony Pictures, WannaCry), bank and cryptocurrency heists (Bangladesh Bank, Ronin, Bybit) and their laundering, the infiltration of companies by fake IT workers, espionage against governments and defence industries, and the international responses and outlook shaped by the rapprochement with Russia and by artificial intelligence.
