Pluang reported that roughly $115 million worth of Bitcoin was stolen in an incident tied to a Coldcard firmware flaw from 2021. The report said 192 victims have confirmed losses connected to the vulnerability.

Coldcard is a Bitcoin-focused hardware wallet brand. Hardware wallets are designed to keep private keys offline, but firmware—the software running on the device—can be a critical security component when users create, store, or authorize access to wallet credentials.

The reported losses underscore the long-term consequences that can arise from security flaws in wallet software, particularly when vulnerabilities affect access to Bitcoin holdings. The report identifies the issue as a 2021 firmware flaw and says the confirmed victim count stands at 192. No additional details about the affected users, recovery efforts, or the mechanism of the theft were provided in the available report.

Why this matters

The reported $115 million loss and 192 confirmed victims make this a material hardware-wallet security incident, challenging assumptions that offline key storage alone protects users from firmware-level risks. It could prompt scrutiny of Coldcard's historical firmware controls, update practices and disclosure processes, while reminding institutions and self-custody users to reassess device provenance and key-generation procedures.
