The US Justice Department charged a North Korean hacker for cyberattacks against Sony Corp and the United Kingdom's National Health Service, according to a criminal complaint released on Thursday.
The hacker, Park Jin Hyok, also was involved in an attack against Bangladesh Bank in 2016, the complaint alleged. It was not immediately clear if North Korea would make Park available to US law enforcement authorities.
The investigation is ongoing and includes activity ranging through 2018, the US Justice Department said.
The charges are part of a strategy by the US government to deter future cyberattacks by naming and shaming the alleged perpetrators.
In 2014, US officials said unnamed North Korean hackers were responsible for a major cyber intrusion into Sony, which resulted in leaked internal documents and data being destroyed.
The attacks came after Pyongyang sent a letter to the United Nations, demanding that Sony not move forward with a movie comedy that portrayed the US-backed assassination of a character made to look like North Korean leader Kim Jong Un.
The FBI said at the time it had recovered evidence connecting North Korea to the attack and others in South Korea.
