In this episode, Steve, Jeff, and I walk through the catastrophic Coldcard entropy failure, how a trusted hardware wallet ended up generating weak keys, and how attackers are now brute-forcing Bitcoin wallets in minutes.

We dig into AI’s role in widening the attack surface, the dangers of source-available over true open source, and our own arrogance around hardware security. I share practical steps to get your coins off compromised devices, why multi-sig saved me this time, and how we can turn this gut punch into genuine anti-fragility for Bitcoin self-custody.
