Investigative journalist Geoff White discusses his new book The Lazarus Heist. It's the story of how North Korea has harnessed cutting-edge technology to pursue a highly effective campaign of cyber-raids to fund its economy. This has included the exploitation of central banks, cryptocurrency exchanges, Hollywood film studios and the UK's National Health Service. Geoff is joined by CFCS's Tom Keatinge and Allison Owen to dive into the mechanics of this cybercriminal threat and its implications for democracies.
