Plainbit traces the CISA-listed North Korea ransomware address 16sYqXancDDiijcuruZecCkdBDwDf4vSEC, which QLUE flagged as Ransomware/North Korea and high risk. The address received and sent 0.06 BTC in July 2019, and its funds were combined with other inputs before being sent to a Binance address also included in CISA's published set. Upstream tracing found funds moving through JoinMarket CoinJoin-style aggregation and peel-chain patterns, with many separated outputs going to BitPay and other inputs traceable to Bitstamp, Upbit, and Hydra Market. The source does not present this as a clear victim-payment path, but it documents laundering infrastructure and exchange touchpoints relevant to DPRK ransomware wallet analysis.
