Fake “Two-Factor Authentication” Prompts Used to Approve Attacker Logins

Threat Level: 🔴 High
Threat Type: Phishing / MFA Fatigue Attack


What’s Happening

Cybersecurity researchers are warning about a rise in attacks known as “MFA fatigue” or “push bombing.” In this scam, attackers attempt to log in to a victim’s account using stolen credentials and repeatedly trigger two-factor authentication (2FA) approval requests.

Victims receive multiple login approval notifications on their phone or device. Eventually, out of confusion or frustration, some users accidentally approve one of the requests, granting the attacker access.

According to reporting from BleepingComputer, some attackers also follow up with phone calls or messages pretending to be IT support, asking the user to approve the login request.


Why This Matters

If an attacker gains access through a 2FA approval, they may be able to:

• Access email, cloud storage, or financial accounts
• Steal sensitive personal or business data
• Send phishing messages from the compromised account
• Move deeper into company systems

Even though two-factor authentication is a strong security measure, these attacks exploit human behavior rather than technology weaknesses.


How to Stay Safe

• Never approve login requests you did not initiate
• If you receive repeated login prompts, deny them and change your password immediately
• Enable number matching or app-based authentication when available
• Report suspicious login activity to your IT or security provider


Bottom Line

Two-factor authentication is only effective if used carefully. If you receive unexpected login approval requests, treat them as a warning sign of a potential attack.
