How US authorities tracked down the North Korean hacker behind WannaCry

Earlier today, the US Department of Justice formally charged a North Korean programmer for some of the biggest cyber-attacks in recent years. According to a 179-page DOJ indictment, the US believes that Park Jin Hyok, a 34-year-old North Korean, is one of the many individuals behind a long string of malware attacks and intrusions, including the WannaCry ransomware outbreak of 2017 and the breach at Sony Pictures Entertainment in 2014.

The DOJ says Park was an active member of a government-sponsored hacking team known in the private cyber-security sector as the Lazarus Group. But in reality, officials say, he was also a government employee working for a government-owned company named Chosun Expo Joint Venture.
