Hyok is said to be an intelligence officer for the Reconnaissance General Bureau, North Korea's military intelligence agency.
He is also a suspected member of the notorious Lazarus Group, a shadowy hacking group linked to multiple cyber-attacks all over the world such as attacks against South Korean banks, military, and news agencies, attacks in neighboring countries such as China and Japan, and most recently against a string of banks and cryptocurrency exchanges.
Even prior to today's charges, previous reports from the cyber-security and real-world intelligence communities have linked the Lazarus Group to Bureau 121, a division of the Reconnaissance General Bureau, a North Korean intelligence agency part of the National Defence Commission.
The damages caused by last year's WannaCry have been estimated at around $8 billion across over 150 countries, according to an IBM report.
The US Treasury Department is also expected to announce new economic sanctions against North Korea at the same time.
Earlier today, before news of the impending charge broke, President Donald Trump tweeted "Kim Jong Un of North Korea proclaims 'unwavering faith in President Trump.'"
This is also not the first time the US has charged foreign intelligence officers for major cyber-attacks.
In 2016, the DOJ charged nine Iranians with connections to the Iran military for cyber-attacks on US banks and a New York dam facility. The DOJ charged another group of Iranians in March 2018 for stealing data from 144 US universities.
In 2017, the US charged two hackers and two members of Russian intelligence for hacking Yahoo's servers and stealing the personal data of 500 million users back in 2014.
In 2017, the US charged three Chinese nationals for cyber-espionage on the part of the Chinese government from behind a fake cyber-security firm.
In 2018, the US and fellow Five Eyes countries formally accused Russia for attacks on the US energy grid and other critical infrastructure, election meddling, but also for orchestrating the NotPetya ransomware outbreak.
The US, in turn, has been accused by Iran for creating the Stuxnet virus that destroyed equipment part of Iran's nuclear program.
