Coldcard Mk3 Firmware Flaw Puts Wallet Seeds At Risk

Crypto hardware wallet maker Coinkite has issued an urgent warning to users of the Coldcard Mk3 device. A newly discovered firmware flaw may have compromised the generation of wallet seed phrases. This issue raises serious concerns about how random numbers are created in older storage devices.

The flaw affects the core security assumptions of the Mk3 model. Anyone using an impacted device should take immediate precautions. Moving funds to a newly generated, secure wallet is the safest path forward to protect digital assets from potential unauthorized access.

Security experts recommend keeping all hardware firmware up to date and following best practices for key generation. Traders and holders using older gear should check official announcements from Coinkite to confirm if their specific device is vulnerable.
