North Korea's Share of Crypto Hack Losses Reached 63% in 2025

North Korea-linked hackers accounted for a growing share of crypto stolen in hacks from 2020 through 2025. The annual figures show the share below 10% in 2021, then at 22% in 2022 and 37% in 2023. It reached 39% in 2024 and 63% in 2025. The 2026 calendar year is still underway. The annual percentages measure the estimated portion of crypto stolen in hacks attributed to North Korea, rather than a dollar total for each year. Eleven governments said North Korean hackers took at least $1.65 billion during the first nine months of 2025.
