Bitcoin Hardware Wallet Hacks Highlight Security Vulnerabilities
Bitcoin hardware wallet hacks in 2026 have exposed vulnerabilities in devices, leading to significant losses. Coinkite’s Coldcard devices and Ledger Nano X and Nano S Plus units were compromised. The Coldcard hack resulted in the theft of an estimated 1,800+ BTC, valued at $100 million to $150 million, while Ledger devices led to losses of $90 million to $100 million.
