Coldcard Ships Firmware Update After $114 Million Bitcoin Theft

Hardware wallet maker Coldcard has released a new firmware update following a massive security breach that cost users $114 million in bitcoin. The company utilized AI assistance to identify additional vulnerabilities during the review process.

Coldcard has shipped a critical firmware update three weeks after completing an extensive security review triggered by a $114 million bitcoin theft. The hardware wallet manufacturer deployed artificial intelligence tools during the review process, which helped identify several bugs unrelated to the original vulnerability that led to the massive loss.

Despite the firmware improvements, the company has emphasized that simply updating the software does not automatically make a previously compromised wallet safe for continued use. Users whose wallets may have been exposed to the original security flaw are being advised to take additional precautionary measures beyond the firmware update.

The incident highlights the ongoing security challenges facing cryptocurrency hardware wallet providers, even those considered industry leaders. The $114 million theft represents one of the larger security breaches in the hardware wallet sector, prompting broader discussions about the balance between user convenience and security in self-custody solutions.

Industry experts note that while the AI-assisted bug discovery represents a positive development in security practices, it also underscores the complexity of securing cryptocurrency storage devices against increasingly sophisticated attack vectors. The company has not disclosed specific details about the original vulnerability to prevent potential exploitation of users who have not yet updated their devices.
