Coldcard Vulnerability Exposes Weak Bitcoin Keys, Triggering Self-Custody Panic
A critical key-generation flaw in Coldcard hardware wallets exposed weak private keys over a five-year period. The security vulnerability threatens self-custodial Bitcoin holdings and is forcing capital back onto major exchanges. Holders must rotate keys immediately to prevent potential fund losses.
Self-custody took a sharp jolt after reports confirmed Coldcard hardware wallets generated weak private keys across a five-year window. The key-generation flaw compromises high-value Bitcoin storage setups, creating severe security risks for legacy wallet holders.
The fallout is forcing traders to rotate private keys or move funds back onto major exchanges to protect their balances. As confidence in isolated hardware devices wavers, centralized custodians are seeing immediate reserve inflows from panicked cold-storage users.
