Coldcard Bitcoin Thefts Slow, But Losses Could Top $150 Million: Galaxy - Decrypt

Coldcard's 2021 firmware downgrade switched RNG from hardware (128-bit) to software (40-bit entropy); attackers reconstructed seeds from serial number and clock state, stealing 1,778 BTC ($112M, possibly $151M with suspected wave 4). For tech managers, the signal is sharp: silent firmware changes on critical hardware wallets demand rigorous vendor audits and custody governance—not blind trust in established brands.

Coldcard wallet exploit leads to theft of over 1,778 Bitcoin worth $112M

Coldcard firmware bug (2021) replaced hardware RNG with predictable PRNG; thieves stole 1,778 BTC ($112M) starting July 30. Firmware-level breach undermines self-custody security—users must regenerate seeds on patched firmware, exposing vendor gaps in RNG validation and patch response time.
