Trezor Phishing Attack: Exploiting Support Emails

Trezor Phishing Attack: Exploiting Support Emails

Trezor recently warned users about a sophisticated phishing attack leveraging its own support email system. Attackers exploited a vulnerability to modify Trezor's automated email responses, inserting malicious links and warnings that appeared legitimate.

While the extent of successful attacks remains unclear, the method raises serious security concerns. This attack likely used data from previous breaches, making tracing the perpetrators challenging.

How the Attack Worked

• Compromised Support Emails: Hackers gained access to Trezor's support system, likely through previously compromised user data and an HTML injection vulnerability.
• HTML Injection: By injecting malicious HTML code into support requests, attackers altered automated responses from Trezor.
• Phishing Emails: The modified emails, appearing to originate from Trezor support, contained fake warnings and links to compromised websites or fake login pages.
• Targeting Users: Attackers likely targeted users who had previously contacted Trezor support, obtaining their contact information from leaked data.

This highlights the need for robust security practices, even for reputable companies like Trezor. The attackers didn't breach Trezor's systems directly but rather exploited existing vulnerabilities and leaked data.

Protecting Yourself

• Verify Email Authenticity: Always independently verify the sender's email address and links before clicking anything.
• Never Share Seed Phrases: Never share your seed phrase or private keys with anyone, including those claiming to be from Trezor support.
• Enable Two-Factor Authentication (2FA): Utilize 2FA on all your accounts to add an extra layer of security.
• Stay Informed: Stay updated on security advisories and phishing attempts by following official Trezor announcements and reputable cybersecurity news sources.
