Trezor data breach widens to 67,000 customers

The breach's expansion beyond the stated retention window suggests a systemic gap between vendor policy and partner data handling, raising questions about operational oversight in hardware wallet supply chains. This affects both current and former Trezor users whose data was retained longer than promised, potentially exposing them to phishing risks. The key issue to watch is whether Trezor can enforce stricter data lifecycle controls across its partners, as trust in physical cold-storage security depends as much on back-end practices as on device encryption.
