Coldcard Wallet Vulnerability Exposes Users to Potential Bitcoin Heist

A vulnerability has been discovered in the Coldcard hardware wallet, which could potentially allow hackers to steal users' Bitcoin.

The exploit, discovered by security researcher Travis O'Brien, affects all versions of the Coldcard wallet prior to version 4.0.

O'Brien demonstrated the attack on a video shared with BitRss, showing how he was able to gain access to a user's wallet and transfer funds without their knowledge or consent.

The vulnerability is particularly concerning for users who store large amounts of Bitcoin on their Coldcard wallets, as it could potentially allow hackers to drain their accounts.
