Trezor, a leading hardware wallet manufacturer, has issued a security warning after discovering that attackers exploited its contact form to send phishing emails. These emails, masquerading as official support replies, attempted to trick users into revealing their wallet backup information. Trezor emphasized that it will never request wallet backups from users, advising that such information should remain offline and private. While the issue has been contained, Trezor urges users to stay vigilant as security is an ongoing process.
