Plainbit concludes its review of 43 CISA-disclosed Bitcoin addresses linked to North Korean ransomware, finding that nine had transaction history, two were Binance-owned exchange addresses, two were not discoverable in blockchain lookups, and seven non-exchange addresses warranted QLUE tracing. The traced flows showed attempts to move or cash out funds through exchanges, Bitcoin ATM services, crypto payment services, Hydra Market, and other cryptocurrency services, with Binance appearing frequently. Some funds touched addresses identified as Lazarus Group-linked, and the analysis observed evasion patterns including JoinMarket CoinJoin, peel chains, and renBTC chain hopping. The conclusion provides a consolidated view of how North Korea-linked ransomware funds moved between 2018 and 2022 and which services appeared in the laundering paths.
