Coldcard entropy bug: the commits that introduced it are worth reviewing

Source → X (Tweet): hodlonaut #BIP-110 on X: "The commits (code changes)..." / X ???? This is why people should learn to VERIFY the things they consume. No excuses! "I am not a programmer, I don't understand code. How am I s...

PSA: to anyone who got their ColdCard wallet hacked, please, don’t do anything stupid.

I mean it. Reach out to friends, family, anyone you trust. Do NOT destroy your ColdCard. If funds are recoverable at some point, they will probably be sent back to their original owners. If you are isolated, feel like something could go wrong or els...

PSA, tomorrow the sun will rise again

I've been where some of you are today. During the FTX collapse, I lost over $2 million USD. The cascade triggered margin calls, then liquidation. In what felt like an instant, six years of stacking disappeared. (Can send proof to mods if needed)...

ColdCard: You’ll never hurt me again!

My seed used with this device was strong and I was unaffected by the security flaw in the RNG setup. Still, I’m re-doing everything. I am moving back to my ledger until I get a multisig setup with a SeedSigner or similar. It’s gonna be a pain t...

Someone did an analysis of hardware wallet's software using kimi k3

How could the Coldcard vulnerability have been disclosed responsibly?

As a thought experiment, suppose a white-hat had been the first to discover the Coldcard RNG vulnerability. How could they possibly have disclosed it responsibly, given that weak seeds had already been generated? A public warning would immediately cr...
