ColdCard users lost ~1,367 BTC (~$89M) because a 2021 firmware bug silently swapped hardware RNG for a software one — the case for multi-source, fail-closed entropy Verification because this sounds unreal: Privacy Guides and The Hacker News both covered it at the start of August 2026 — attackers drained thousands of ColdCard wallets for a total of ~1,367 BTC (~$89M). Root cause: a firmware bug from 2021. During seed generation some devices silently fell back from the hardware RNG to a weak software RNG. The 24-word seeds looked completely normal — no warnings, nothing. But they could be reconstructed offline, years later. The scary part is that weak randomness looks identical to good randomness, right up until someone else derives your keys. ColdCard's incident was a trust failure: a single chain of trust ("one certified chip from a trusted vendor") that had a silent fallback path. It's now the clearest proof that one point of trust in entropy is one point of failure.
