How crypto hacking funds isolated North Korea’s nuclear programme

Cryptocurrency theft is estimated to generate half of the country’s foreign currency income

North Korea plays by its own rules. The isolated, secretive and autocratic country is largely cut off from the world’s economic system – but when it comes to generating foreign earnings it relies on some of the world’s most sophisticated hacking.

Experts, such as TRM Group, quickly attributed the extraordinary $6.3bn (£4.7bn) Binance cryptocurrency theft to TraderTraitor, an elite North Korean hacking unit that has also been known as the Lazarus Group. Though the link may not be proven yet, the pattern of behaviour is familiar.
