FBI Warns of Active Campaign Targeting Microsoft 365 Users

The FBI warns that a new scam service is being used to trick Microsoft 365 users into handing over their login details and to get around extra sign-in protection.


Who Is at Risk

Anyone who uses Microsoft 365, especially people at work or anyone who signs in with a password and extra verification.

What to Watch For

Watch for unexpected sign-in pages, emails asking you to log in again, or messages saying your account needs urgent attention.

What to Do

If you get a suspicious sign-in request, do not enter your password; go directly to the official Microsoft 365 site and change your password if anything looks wrong. Questions? Visit nationalcybersecuritycenter.org/personal-cyber-advisor to get step-by-step guidance.
