Cold Card Bitcoin hardware wallet drained 1,600 BTC via flawed random number generator

Cold Card, a security-focused airgapped Bitcoin hardware wallet, was exploited due to a firmware bug where MicroPython's random number generator was not properly disabled, generating weak seed phrases for 5 years. Over 1,600 BTC (~$100M) was drained from 7,000+ wallets without malware or phishing. This is a cryptocurrency security story with no AI signal.
