But we saved everything 🙂.

Thorn previously flagged an ongoing attack targeting BTC addresses generated by Coldcard wallets, urging holders to secure their funds in an earlier report on the security warning. He also discussed the latest developments in the Coldcard wallet hack investigation during a live appearance covering Coldcard and AI topics. An update from Coldcard was anticipated at that time.
