According to CoinMeta, the leakage of user addresses by hardware wallet companies can lead to the unauthorized use of personal data. Users should take measures to protect themselves from phishing, SIM card swapping, and physical security risks. Hardware wallets are designed to isolate private keys from internet devices, but purchasing one may expose users' names, email addresses, phone numbers, and home addresses. In the event of a leak, users should first confirm the information that has been compromised and take precautions against potential attacks such as phishing and account takeover. Recent Trezor incidents have shown that the system of logistics provider ShipMonk was accessed without authorization, resulting in the leakage of information for 13,689 customers; however, the wallets and their private keys were not affected. Users should avoid entering their mnemonic phrases in unsolicited security emails and ensure that their email accounts use strong passwords and multi-factor authentication.
