- Coinkite Releases Fixed Firmware After Coldcard Bug; AI Likely Involved In The Breach
Coinkite released fixed firmware for Coldcard hardware wallets after a critical bug compromised private key generation, potentially stealing over 1,000 bitcoins. The vulnerability, likely involving AI in the breach, affected Coldcard MK3 devices with specific firmware versions. Users who did not use dice rolls or BIP 39 passphrases are at risk, and Coinkite advises firmware updates and wallet migrations to secure funds.
- COLDCARD SECURITY RISK: IMMEDIATE ACTION REQUIRED
Coldcard wallets (MK3, MK4, MK5, Q) have a critical security vulnerability allowing attackers to brute-force seed phrases if generated without sufficient entropy (e.g., 50+ dice rolls). Funds are actively being drained, with 1000 BTC reported moved. Immediate action is required to move funds to secure wallets, use passphrases, or adopt alternatives like Nunchuck.
