Explains how a five‑year‑old firmware bug effectively disables the RNG, producing 22‑bit entropy seeds and enabling the theft of about 1,800 BTC; traces the exploit through public commits, unusual transaction patterns, and sloppy code maintenance with no bug bounty or audit. Demonstrates that multi‑vendor multi‑sig setups (and tools like Lyanna) would have prevented mass loss, and recommends continuous AI-enabled code audits and concrete processes (commit reviews, checklists, bounties) to harden hardware‑wallet security.
