Popular hardware wallet manufacturer Trezor has suffered a significantly larger security breach than initially reported, with an additional 67,000 customers exposed in the fallout. The expanded data leak stems from a compromise of a third-party support portal, which malicious actors accessed to harvest sensitive user information. While core cryptocurrency funds remain secure due to the offline nature of hardware wallets, the exposed details put victims at heightened risk of targeted phishing attacks. Trezor has reached out to the newly identified individuals to warn them of potential scams and urged users to remain vigilant against fraudulent communications. This incident underscores the ongoing cybersecurity challenges faced by crypto infrastructure providers as they grapple with third-party vendor vulnerabilities.
