🚨 A fourth wave of security sweeps is targeting Bitcoin addresses generated by Coldcard hardware wallets.
Over 1,360+ $BTC across thousands of addresses has already been drained since the exploit began on July 30.
Fortunately, researchers note that attackers enabled Replace-By-Fee (RBF), giving victims a narrow window to override pending mempool transactions with a higher fee.
If you hold funds in a Coldcard wallet, check your unconfirmed transactions and secure your assets immediately! 👇
