Why it matters: A hardware wallet is supposed to solve one problem: keep your Bitcoin keys somewhere no attacker can reach them. This week showed what happens when the flaw sits inside the wallet itself. A firmware bug that's been shipping in Coldcard devices since 2021 let an attacker guess supposedly random seed phrases from the outside, no physical access, no phishing, no malware required, and drain funds from thousands of addresses. The running total is already past $88 million, and it's still climbing.
The operation has run for nearly a year, impersonating 72 popular Windows tools to steal crypto and passwords

The fraudulent sites reportedly distribute malware capable of compromising user privacy, hijacking account credentials, and draining crypto wallets.
