The article traces funds from the WannaCry 2.0 ransomware wallets as they moved from Bitcoin into Monero and later back toward transparent BTC and BCH blockchains. It notes preliminary reporting that attributed WannaCry to North Korea’s Lazarus Group, then uses public block explorers, Neutrino reporting, and ShapeShift API data to analyze the actors’ chain-hopping activity. The method centers on flagged Monero transaction outputs, ring-member searches, and an output-merging heuristic to identify likely consolidation transactions despite RingCT privacy protections. The finding matters because it shows how exchange data leakage and transaction-pattern analysis can undermine privacy-coin obfuscation in a real ransomware proceeds case.
