Coldcard urges users to move bitcoin as active wallet exploit continues
Coldcard has issued an urgent warning to users to migrate their bitcoin funds due to an active firmware exploit. The vulnerability affects specific older models and firmware versions, potentially allowing attackers to drain wallets.
Why it matters
This is a critical security alert for cryptocurrency holders, as the exploit has already resulted in significant financial losses.
"Please treat this as urgent. Migrate your funds," the company wrote , adding that the threat is active and asking users to warn holders who are "less online" and may not have seen the alert. Those are the wallets most exposed, since the fix has to be done by hand.
Please treat this as urgent. Migrate your funds. Follow the advisory for your model, upgrade your device, generate a new seed, and carefully move your funds. Help spread the word, especially to people who are less online and may not see this update. The threat is still ongoing. https://t.co/cbJxJles8x
The warning is not precautionary. CoinDesk reported Monday that a possible fourth wave of sweeps ran through the day, taking roughly 449 BTC from 709 addresses on Galaxy Research's revised count and lifting cumulative losses from about $89 million to as much as $114 million.
