A reported exploit affecting Coldcard hardware wallets has prompted a warning for holders to move their Bitcoin funds, as the incident continues to raise questions about the security of self-custody setups.
The core concern is straightforward: an ongoing Coldcard exploit has put stored Bitcoin at risk, and affected users are being urged to relocate their coins to a secure destination. Coldcard has urged users to move Bitcoin while the exploit remains in progress, framing the action as a precaution rather than a guarantee that any individual wallet is compromised.

The scale of the incident has been significant. The exploit had drained at least $38 million so far, a figure that has shaken confidence in self-custody and, according to that reporting, may push some investors toward exchange-traded funds.
The reasoning behind the warning ties directly to wallet risk. If a device or its associated wallet data can be exploited while still in use, coins that remain in place could be exposed to attackers even without the owner authorizing a transfer.
Because the exploit is described as still in progress, the safest posture for anyone who suspects exposure is to move funds rather than wait. The incident surfaced during a broader Bitcoin sell-off, adding pressure on holders already watching volatile conditions.
Not everyone needs to act with the same urgency. Users who confirm or reasonably suspect their setup is affected are the priority group, while others may only need to monitor official guidance and device status for further updates.
The first step for anyone with confirmed or suspected exposure is to move Bitcoin to a secure destination that is not tied to the compromised setup. This is the central action behind the warning itself.
Users should also verify official guidance directly, checking device status and wallet configuration rather than relying on secondhand instructions. Reporting has tracked the incident closely, including an update indicating that 15 attackers exploited the wallet flaw, which underscores that the threat is not isolated to a single actor.
Finally, holders should review how their backup phrase is stored and reassess broader account security. The flaw has been linked to large-scale Bitcoin theft, making careful handling of recovery material and related access a priority while the situation develops.
