Security firms confirm at least 1,432 BTC drained from victims, with estimates rising as more reports surface.
Security researchers have traced at least 1,432 BTC stolen in the Coldcard hardware wallet hack, with total losses potentially exceeding 1,800 BTC. Victim reports and on-chain analysis identified over 5,200 compromised addresses across four attack waves, though estimates remain fluid as new data emerges.
Earlier tallies placed confirmed losses at 450 BTC, but broader pattern analysis expanded the figure. Independent firms like TRM Labs and CryptoQuant corroborated the range, though some withheld unverified funds to avoid false positives. Attackers recently moved 64 BTC and 200 ETH to cryptocurrency mixers, complicating recovery efforts.
Analysts warned the final tally may rise further as more victims disclose hacked addresses. The attack targeted individual users, limiting direct market impact but raising security concerns for hardware wallet holders.
