New Scam Alert: Microsoft 365 Users and Vishing Attack

Tech Digest reported:   

The attack begins with a deceptive phone call or a high-priority email notification. Fraudsters often pose as Microsoft technical support or IT security staff, alerting the victim to a “security breach” or a “blocked login attempt” that requires immediate verification.

During the conversation, the attacker instructs the user to visit the legitimate Microsoft device login page and enter a specific eight-digit code provided by the hacker.

Once the victim enters the code, they are essentially granting the attacker’s device authorization to access their account. This allows the hacker to bypass multi-factor authentication (MFA) entirely, as the user has “verified” the session through their own trusted device and credentials.

Key Takeaway:  Authenticate phone callers by asking identifying questions.  For company employees ask information that is available on your company intranet, but not available in social profiles.
