Coldcard Firmware Bug Affects Thousands of BTC Wallet Owners

A serious firmware bug has compromised thousands of Coldcard hardware wallets, leaving more than 4,585 Bitcoin wallet owners vulnerable. The issue stems from faulty software present on devices manufactured or updated between March 2021 and late last week. Coinkite, the company behind the hardware, has acknowledged the issue and expressed regret while promising to assist those looking to pursue police reports or insurance claims.

For those affected, taking immediate steps to secure remaining funds is the first priority. Experts advise documenting every detail of the loss, including transaction IDs, drained wallet addresses, and balance screenshots. Filing a formal report with local law enforcement is a vital move, as these records are typically required for insurance claims or future civil legal actions.

Victims should also report the theft through official federal channels, such as the FBI Internet Crime Complaint Center. Be wary of opportunistic scammers who may reach out claiming to be law enforcement or legal firms that can recover your funds. Real authorities will not contact you proactively to solicit money or information, so always initiate contact through official, verified portals.

If you are considering a civil lawsuit against Coinkite, ensure you verify any potential attorney through your state bar association. With scammers often posing as legal experts to target vulnerable victims, checking the license status of a professional is essential. Consulting with a qualified tax advisor is also recommended to discuss how to document these losses for tax purposes.
