According to CoinMeta, North Korea is accused of accounting for over 75% of hacking activities in the cryptocurrency sector. Based on data from TRM Labs, since 2017, North Korean hackers have stolen approximately $12.8 billion in cryptocurrency assets. In just nine months of 2025, hackers stole at least $1.65 billion, which is 3.5 times North Korea's legal export revenue for that year. The United States Federal Bureau of Investigation (FBI) also accuses North Korea of being involved in the $1.5 billion hack incident in February 2025. North Korean hackers are mainly managed by their primary espionage agencies, with famous hacking groups including Lazarus Group and Andariel. In addition to cryptocurrency assets, North Korea is also accused of being involved in several major cyberattacks, including the attack on Sony Pictures in 2014 and the theft of $81 million from the Central Bank of Bangladesh in 2016.
