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...
