Galaxy Research: Three Suspected Attacks on Coldcard-Generated Addresses Drain 1,367 BTC Galaxy Research said its Bitcoin on-chain analysis identified three suspected attack waves targeting addresses generated by Coldcard, involving 4,585 addresses and a total of 1,367.05 BTC worth about $88.6 million. The first two waves shared similar transaction patterns and may have been carried out by the same operator, although this has not been proven. The third differed substantially and could reflect either revised tooling by the same attacker or a separate actor targeting the same vulnerable key space. Galaxy stressed that the analysis is based solely on blockchain data and has not confirmed whether the affected addresses were generated with insufficient randomness.
