🚨 Moral of the story: Don’t be the next Coldcard
A single, quiet entropy failure in firmware that shipped years earlier turned one of the most respected Bitcoin hardware wallets into a public hunting ground. Nearly $89 million drained across thousands of addresses. No physical access required. No seed phrases stolen. Just weak randomness that left private keys predictable on the open blockchain.
The lesson is brutal and simple:
Reputation is not security.
A long track record is not a guarantee.
“Cold” is not the same as correct.
If your product (or your personal setup) relies on a single assumption about randomness, generation, or firmware integrity that has never been stress-tested under real adversarial conditions, you are already a candidate for the next headline.
Don’t ship the flaw.
Don’t ignore the old code.
Don’t assume quiet years mean the problem is gone.
Because once the scanners start running, the only question left is how many wallets get emptied before the story carries your name.
