Event Summary

Hackers exploited a software flaw in Coinkite's Coldcard hardware wallets, which are designed for secure offline storage of Bitcoin. The flaw made the generated seed phrases predictable, allowing attackers to systematically recalculate and drain funds. By August 3, approximately 1,367 Bitcoin worth about $86 million had been stolen from over 4,500 wallets, according to YouGov. Coinkite notified users late last week and has released fixed firmware for affected models. The attack highlights the risks of self-custody and the importance of true randomness in cryptographic security. Losses escalated from $38 million on July 31 to $86 million by August 3. The incident has drawn widespread attention and raised concerns about the safety of cold wallets.
