Coldcard Hacker Gets Brazen Bitcoin Laundering Offer Onchain

Coinkite disclosed a firmware RNG bug allowing attackers to drain 1,359.88 BTC from Coldcard wallets; stolen funds remain in attacker addresses, with a 10% laundering offer posted onchain. The combination of unfixable weak seeds, bricking firmware updates, and failed entropy generation forces CTO and self-custody users to rethink hardware wallet trust models and storage strategy.
