COLDCARD RNG Vulnerability Exposed, 2023 Dice Roll Weak Seed Warning Resurfaces

A 2023 warning about COLDCARD Mk4 weak seeds from single dice rolls gains traction after an RNG vulnerability discovery, highlighting risks of user interface misconceptions regarding hardware entropy mixing.

Woofun AI reports that a 2023 video by hardware wallet educator @YTCryptoGuide has regained attention following the discovery of a COLDCARD RNG vulnerability. The educator warned that the COLDCARD Mk4 permits wallet creation via a single dice roll, potentially generating extremely weak seeds. He noted that the interface may mislead users into believing their dice results mix with the device's hardware RNG, whereas certain operational flows do not support this. Many advanced users rely on dice rolls due to distrust of hardware RNG, making this historical warning newly significant.
