Chainalysis reports that North Korea-affiliated hackers stole about $1.34 billion across 47 cryptocurrency hacks in 2024, representing 61% of the total stolen value and a major increase from the revised 2023 figure of $660.50 million. The DPRK-linked activity is described as frequent and high-value, with more attacks above $50 million and above $100 million than in 2023, while some smaller incidents may relate to North Korean IT workers infiltrating crypto and Web3 companies through false identities, hiring intermediaries, and remote-work access. The excerpt emphasizes private key compromise as the largest 2024 attack vector overall and notes that stolen funds were often laundered through bridges and mixing services. In the DMM Bitcoin case study, a North Korea-affiliated hack of the Japanese exchange led to the theft of about 4,502.9 BTC worth $305 million, with funds moving through intermediary addresses, a Bitcoin CoinJoin mixing service, bridging services, and Huione Guarantee.
