Cole states that Coldcard devices were capable of creating random seed phrases and had the necessary hardware and code, but that normal seed creation used a different weaker source instead, producing non-random seed phrases that were easy to crack. Held as a dated technical framing of the bug from a contributor to the passphrase-drain discussion. The description is the poster's own and is not independently verified here.

This post is registered as evidence and has a locally held capture. The original remains the canonical publication.
