**Firmware Coldcard 5.6.1 forces users to add entropy to every new seed after a $100M hack**
- Coinkite has released a firmware update for the Coldcard, requiring users to manually provide a random source when creating a new wallet seed after a vulnerability exposed customers’ funds.
- The update includes a verification process to ensure that random number generation calls are routed to the intended hardware component, and it also replaces the previous random number generator with the safer SHA-256 Hash_DRBG.
- Users with seeds that may have been compromised—created between 2021 and July 2026—are advised to generate a new seed and move their Bitcoin, because the update does not protect existing vulnerable seeds.
