South Korea links 2019 crypto heist to North Korea

South Korean police have confirmed that hackers linked to North Korea’s military intelligence agency were behind a 2019 Ethereum cryptocurrency theft valued at 58 billion won ($41.5 million at the time). Hackers infiltrated a crypto exchange and stole 342,000 Ethereum tokens, which are now worth over 1.4 trillion won ($1 billion).

The stolen funds were laundered through three hacker-controlled crypto exchanges and 51 other platforms, according to South Korea’s National Police Agency. While the exchange targeted was not officially named, South Korea-based Upbit had reported a similar transfer to an unidentified wallet during the incident. The investigation, conducted with the FBI, used IP address analysis and asset tracking to trace the theft to groups reportedly tied to North Korea’s Reconnaissance General Bureau.

This marks the first confirmed instance of North Korean hackers targeting a South Korean crypto exchange. Previously, a UN report linked North Korea to nearly $3.6 billion in crypto heists from 2017 to 2024. South Korean investigators recovered a small fraction of the stolen assets, equivalent to 600 million won, which were returned to the exchange. North Korea denies involvement in such activities despite mounting evidence to the contrary.
