Coinkite Warns Coldcard Mk3 Owners After Reports of $38M Bitcoin Loss

Coinkite warned Mk3 owners after 594 BTC moved from dormant wallets July 30, traced to weak randomness in firmware 4.0.1–5.0.3. Hardware wallet compromise requires immediate seed migration for unprotected users; passphrase protection provides interim mitigation while Mk3 devices face elevated risk.
