TREE NEWS reports: Galaxy Research’s latest tracking shows the Coldcard ‘Wave 3’ attacker continues to move stolen funds, having transferred about 45% of the total stolen coins. The attacker created 293 2-of-2 multisig vaults per victim, and since Sept. 2 has moved funds via THORChain to Ethereum, then to CoinJoin mixers. Vaults ranked 1-11 have been processed in order of amount, while the next 10 untouched vaults hold 30.81 BTC and vaults 61-293 hold 33.77 BTC. Total stolen may reach 1806 BTC.
Galaxy Research: Coldcard attacker moved ~45% of stolen assets
The attacker's methodical, automated drain—processing vaults in descending order of value—suggests a deliberate strategy to maximize extraction before detection or intervention. The use of THORChain and CoinJoin mixers indicates a sophisticated laundering pipeline, which could complicate recovery efforts and set a precedent for how cross-chain theft is traced. With roughly 55% of assets still in untouched vaults, the pace and pattern of future transfers will be the key signal for whether the attacker accelerates or encounters friction. For the broader market, this highlights the persistent risk in hardware wallet custody, even when multisig setups are used, and raises questions about the effectiveness of current tracing and freezing mechanisms.
