A firmware vulnerability in Coldcard Mk3 hardware wallets allowed attackers to predict wallet seeds and steal 1,367 BTC (about $88.6M) in three waves, with the largest theft occurring in just 41 minutes. The flaw, present in firmware versions 4.0.1 and later, caused weak random number generation, enabling offline enumeration of seeds and unauthorized fund sweeps without physical device access. Users with affected devices are urged to move funds to new wallets on unaffected hardware models to avoid loss. This incident highlights risks in hardware wallet security and the importance of firmware vigilance.
