Coldcard Firmware 5.6.1 Forces User Entropy Into Every New Seed After $100M Exploit
đČ Coinkite has released a firmware update for Coldcard that requires users to manually provide randomness through dice rolls, coin flips, or key presses before generating a new wallet seed, following a security breach.
đ The update addresses a defect in the random number generator that previously allowed attackers to exploit vulnerable seeds, resulting in the loss of over $100 million in Bitcoin.
â ïž Users with affected seeds are advised to create new wallets and migrate their funds, as the update does not secure existing compromised seeds, and older models Mk2 and Mk3 are not included in this release.
