The attack, which began last Thursday, exploited a five-year-old firmware flaw in the hardware wallets, affecting approximately 7,300 addresses. In response, Coldcard maker Coinkite has patched all affected devices, and attacker addresses have been shared with U.S. federal law enforcement. Klippsten noted that while the incident was severe, it is accelerating the adoption of more robust collaborative multisig security solutions, with users moving towards products like Swan Vault to enhance their self-custody practices rather than abandoning them.
