The Lazarus Heist

They have been accused of causing mayhem in Hollywood with the infamous Sony hack. They're allegedly behind WannaCry, a cyber-attack that brought NHS hospitals to a dangerous standstill. And it has been claimed that they have stolen more than $1 billion in an international crime spree.

North Korea denies the allegations, saying the accusations are American attempts to tarnish its image. From the streets of Dhaka to the casinos of Macau to the secretive capital of Pyongyang, this shocking story uncovers the secret world of the Lazarus Group, their victims and those who have tried - and so far failed - to stop them.
