Plainbit analyzes CISA-listed North Korea ransomware Bitcoin address 1J8spy62o7z2AjQxoUpiCGnBh5cRWKVWJC, which QLUE flags as high-risk ransomware/North Korea infrastructure in cluster 828661150. The wallet recorded five transactions and moved 1.87482707 BTC, with incoming funds from Binance, Bithumb, and Gemini and all received BTC later sent onward to Binance. The Bithumb 0.1 BTC transfer is assessed as likely victim ransom activity, while a Gemini-linked transaction also distributed funds to Bitcoin Depot, Bitmart, and Bybit, suggesting attacker-controlled fund movement rather than a simple ransom payment. The report is useful for tracing how North Korea-linked ransomware funds touched exchanges, Bitcoin ATM services, and other crypto services.
