Are you aware that a new wave of attacks on Coldcard wallets has been spotted, putting thousands of Bitcoin at risk?

Cold cards are special hardware wallets designed for advanced users, but even they aren't immune to attacks. One of these attacks, called a transaction malleability attack, can allow scammers to intercept and manipulate transactions.

Here's how it works: when a cold card user initiates a withdrawal, the transaction is broadcast to the network but isn't yet confirmed. Scammers can see this unconfirmed transaction and alter it, changing the recipient or the amount. This altered transaction is then sent to the network, and it could be accepted as a legitimate transaction if the original transaction is timed out.

The Galaxy research head, Alex Thorn, warns that this is exactly what happened in the recent attacks, with 389 Bitcoin stolen so far. This issue highlights the ongoing cat-and-mouse game between scammers and wallet creators, and it's essential to stay vigilant to protect your funds.

So, what's your take on this situation? Should you prioritize security when using your cold card, or do you trust that the technology is secure enough? Share your thoughts in the comments! #ColdCardAttacks #BitcoinSecurity #WalletProtection
