New Email Phishing Threat Targets Microsoft 365 Users

We recently defended against this new email phishing threat targeting Microsoft 365 users. The email is entirely in the form of an image in an attempt to bypass anti-spam text classifiers. The email claims that the recipient’s password has expired and provides a link to a fake login page that closely emulates the official Microsoft 365 login page.

Clicking the link brings the recipient to a landing page requesting login credentials. Attempting to login with false credentials returns an error, indicating that the attacker is actually proxying the request across. The next step would likely be to input a 2FA token, giving the attacker full access to the account.

Please be careful when you receive emails claiming that your password has expired, and always verify the authenticity of any login pages before you enter your credentials. If you receive a suspicious email, do not click on any links or enter any personal information. Instead, please report the email to your IT department for further investigation and recommend MailGuard to help prevent future phishing attempts.

  • Are from businesses that you were not expecting to hear from, and/or
