Coldcard, a popular Bitcoin hardware wallet manufacturer, has issued a fresh warning to its users: the security threat stemming from a recent hack is still active, and funds remain at risk. The company, which has already seen approximately 1,816 BTC ($114 million) drained from user wallets due to a code flaw, is now urging all users to apply a security update, generate a new seed phrase, and move their assets to a safe address immediately.
What Happened: The $114M BTC Hack
The incident first came to light when multiple users reported unauthorized transactions from their Coldcard wallets. Investigators traced the root cause to a vulnerability in the device’s firmware—a flaw that could be exploited remotely, allowing attackers to access private keys. Galaxy Research, a blockchain analysis firm, initially estimated that losses could reach as high as 2,055 BTC, but the confirmed figure has already surpassed $114 million, making it one of the largest hardware wallet breaches in recent years.
The exact method of exploitation is still under investigation, but Coldcard’s official update on X (formerly Twitter) confirmed that the vulnerability is not yet fully patched. “The threat remains,” the company stated, advising users not to delay protective measures.
Why This Matters for Coldcard Users
Hardware wallets are widely considered the gold standard for secure cryptocurrency storage, as they keep private keys offline. However, this incident underscores that no solution is completely immune to sophisticated attacks. For Coldcard users, the stakes are high: if they have not yet updated their firmware or generated a new seed, their funds could still be vulnerable.
Coldcard’s guidance is clear—do not just install the update; create a new seed phrase and transfer all holdings to a fresh wallet. This step ensures that even if the old keys are compromised, the new wallet remains secure. The company also emphasized that users should not use any existing backup of the old seed, as it may be compromised.
Market and Industry Impact
The hack has sent ripples through the cryptocurrency community, raising questions about the reliability of even the most trusted hardware wallet brands. While the Bitcoin market has not seen a major price swing directly tied to the incident, the psychological impact on users is significant. Many are now reconsidering their storage strategies, with some turning to multi-signature setups or custodial services for added protection.
Security experts are also using this event to highlight the importance of regular firmware updates and the need for users to stay informed about potential vulnerabilities. “Hardware wallets are not a set-and-forget solution,” noted a blockchain security analyst. “Users must actively manage their devices to ensure they are protected against emerging threats.”
What Users Should Do Now
Coldcard has provided a step-by-step action plan for all users, whether or not they have been directly affected:
- Install the latest firmware update from the official Coldcard website immediately.
- Generate a new seed phrase using the updated device.
- Transfer all funds from the old wallet to the new one, and verify the transactions on the blockchain.
- Do not reuse the old seed phrase or store it anywhere online.
- Consider using a passphrase for additional security.
Users who have already lost funds are advised to contact Coldcard support and report the incident to local authorities, as well as to blockchain forensic firms that may be able to trace the stolen assets.
Conclusion
The Coldcard hack is a stark reminder that in the world of cryptocurrency, security is a continuous process, not a one-time purchase. As the investigation continues and the threat remains active, users must act swiftly to protect their assets. Coldcard’s latest advisory is not just a recommendation—it is a critical step to prevent further losses. For now, the community watches closely, hoping that the breach is contained and that lessons learned will lead to stronger security across the industry.
