Bitcoin on-chain analysis identified three suspected attack waves involving 4,585 addresses tied to addresses generated by Coldcard, pointing to a potentially broader wallet-security concern.
Galaxy Research said its Bitcoin on-chain analysis found three suspected attack waves targeting addresses generated by Coldcard, with 4,585 addresses involved and total losses of 1,367.05 BTC. The finding points to a possible wallet-security issue affecting a large cluster of addresses and suggests the activity unfolded in multiple coordinated phases rather than a single incident.
