Can’t help but think about this

It is unfortunate to see people spreading AI-generated disinformation, especially the CEO of a Bitcoin security company. Posting unverified Claude output for attention, especially when you are trusted by so many people, I don’t know what to say. View quoted note →

Since apparently it is not simple enough: 🚨 If your *passphrase* was generated using the Coldcard, assume it is leaked. ⚠️ If you used microSD to store your passphrase, destroy the microSD, as it can be decrypted. ⚠️ If you used Coldcard Cosign and did not set your own seed, assume the privacy of your funds is rekt. ⚠️ If you split your seed with SeedXOR, only one part of it can be used to get the whole seed. (Most of the time) ⚠️ If you used the password generator on the Coldcard, consider the generated passwords compromised. ✅ If you previously used HSM mode, that is fine. Stop using it, though. ✅ Key teleport is safe. ✅ If your seed was generated with dice, it is safe. View quoted note →

On Twitter, there is some AI-generated misinformation going around about the safety of dice-generated seeds. Only in the following cases are your seeds NOT SAFE: 🚨 You generated your seed with the Coldcard. 🚨 You used the Password Generator to generate a passphrase, along with a CC-seed. In the following cases, your funds are SAFE, but you need caution: ⚠️ SeedXOR: If you used the TRNG option, only one of your shards may be enough to recover the seed. However, they must find the specific shard. ⚠️ MicroSD 2FA: The passphrase stored on the SD card can be decrypted. If you destroy it, you’re fine. ⚠️ Cosign: If you used a CC-generated key, the co-sign can be bypassed + your privacy gone. Otherwise, 0 risk. ⚠️ Password generator: Passwords generated by it are not safe. Rotate them, but this has no impact on your funds. In the following cases, your funds are SAFE: ✅ HSM mode: The weak RNG was used, but does not have any impact on fund safety. ✅ Key Teleport: The weak RNG-generated password was used on top of ECDH, which nullifies risks. ✅ Dice generation: This uses a standard algorithm.

It is weird to see that people trust AI to evaluate the security of whatever HWW they use. These models cannot form independent opinion, and only repeat what people already said. From my testing, they get an egregious number of things extremely wrong. But I guess these models are trained to *sound* like an expert in everything, so…

Don’t overcomplicate your code View quoted note →

If you are disposing of your Coldcard, please take extra measures to overwrite the seed and PIN before disposing of it.

There are too many falsehoods being spread about security. I guess it is the Dunning-Kruger curve, which is expected. Podcasts and HWW companies are to blame. View quoted note →

What do people actually think the benefits of a Bitcoin-only edition of an HWW are?!

I have pushed an update to Damus Translate which should increase the quality of nuanced translations and reduce some false positives
