North Korean-Linked Large-Scale Cryptocurrency Thefts in 2025
North Korean hackers were responsible for stealing over $2 billion in cryptocurrency in 2025, marking a 51% increase from the previous year and pushing their all-time total to $6.75 billion. The attacks were characterized by fewer but significantly larger breaches, with the compromise of Bybit alone resulting in the theft of approximately $1.5 billion. Attackers increasingly relied on embedding IT workers within crypto services and using sophisticated impersonation tactics to target executives, while also showing a preference for Chinese-language money laundering services and rapid laundering cycles.
Chainalysis data revealed that more than $3.4 billion in cryptocurrency was stolen industry-wide in 2025, with the majority of losses concentrated in a handful of high-impact incidents. The top three hacks, all attributed to North Korean actors, accounted for 69% of confirmed breaches. While individual wallet compromises surged in number, the total value stolen from these incidents decreased, suggesting improved security practices in some areas. However, the scale and sophistication of nation-state attacks on centralized services remain a critical threat to the cryptocurrency ecosystem.
