Coldcard Releases Firmware Update After $114 Million Bitcoin Loss, Cites AI‑Assisted Bug Hunt
Coldcard’s new firmware follows a three‑week review that uncovered additional issues unrelated to the vulnerability that led to a $114 million theft, but the update does not guarantee safety for compromised devices.

Coldcard, a hardware wallet manufacturer, has issued a firmware update in the wake of a security breach that resulted in the loss of approximately $114 million worth of Bitcoin. The company says the update was developed after a three‑week internal review that identified several bugs, some of which were discovered with the assistance of artificial intelligence tools.
Review Findings and New Issues
The review uncovered problems that were not directly linked to the exploit responsible for the theft. These additional bugs highlight the complexity of securing hardware wallets and the ongoing need for rigorous testing.
Limitations of the Firmware Update
Coldcard emphasizes that applying the new firmware does not retroactively protect wallets that were already compromised. Users who may have been affected by the original vulnerability are advised to consider additional security measures.
Role of AI in the Bug‑Finding Process
The company reports that AI‑driven analysis helped surface several of the newly identified issues, accelerating the identification and remediation process.
