This is not a drill. On July 30th, 594 Bitcoin — roughly $38 million — was swept from 500 wallets in about 25 minutes. Nobody was phished. Nobody's device was touched. A firmware bug in Coldcard meant the random numbers generating people's seed phrases weren't actually random. A predictable seed is a math problem an attacker can solve. Zach — who owns a Mark III — breaks format to give you the immediate action steps first, then walks through the full timeline, the entropy failure explained simply, what a BIP39 passphrase would have protected, why multisig across multiple vendors is the structural fix, and the habits that protect you regardless of who makes your wallet.
