US prosecutors have accused the North Korean regime of orchestrating a global cyber crime wave that included robbing $81m from Bangladesh’s central bank and spreading the global WannaCry malware attack last year.

Criminal charges unsealed by the US justice department on Thursday alleged Park Jin Hyok, a North Korean hacker, was ordered by Kim Jong Un’s regime to carry out the attacks. The filing includes unnamed co-conspirators, and a DoJ official said the investigation was ongoing.

In addition to the Bangladesh and WannaCry attacks, federal prosecutors accused Mr Park of hacking corporate emails at Sony Pictures in 2014 and a failed attempt to break into Lockheed Martin, the American defence contractor that built an anti-missile defence system deployed in South Korea.
