Coldcard Attackers Move Funds Amid Unresolved Theft

The largest known Coldcard attacker has been identified as controlling 1,159 BTC across seven addresses.

Despite being a significant amount of cryptocurrency, none of the funds have entered mixers or been transferred to an identifiable cash-out service.

A separate attacker, however, has started routing smaller amounts through a mixer. On-chain investigators detected 64 BTC entering a transaction flow linked to a mixer.

The activity appears to be separate from the seven-address cluster holding 1,159 BTC and raises questions about the number of attackers involved in exploiting the Coldcard vulnerability.
