Coldcard hardware wallet warns of an active exploit, urges moving funds

Coldcard, a company that makes physical devices for storing bitcoin offline (often called cold storage), told users there's an active security exploit affecting some devices. Because the issue is still being actively exploited, they're recommending users move their bitcoin to a new, safe wallet rather than wait for a patch.

If you own a Coldcard device, this is worth paying attention to now, not later, since the risk is live rather than theoretical. If you don't use this specific hardware, it doesn't directly affect you, but it's a reminder that even offline storage isn't automatically risk-free.

If you use a Coldcard device, check the company's official channels directly (not links from social media or email) and follow their specific instructions to move funds to a new wallet. If you don't use one, there's nothing to do here.
