Beware of Push Bombing —The MFA Scam Designed to Wear You Down

Cybercriminals are getting smarter about bypassing multi-factor authentication (MFA), and one of their favorite tricks is something called push bombing. It’s a simple tactic, but extremely effective when victims are caught off guard or overwhelmed. And most of us have probably been overwhelmed by notifications at some point, so this type of attack has proven successful time and again for attackers.
Push bombing (also referred to as MFA fatigue) happens when criminals get hold of your username and password—often through phishing, data breaches, or reused passwords. Then, because you have MFA enabled on your accounts (as you should), they try to get you to approve a login. Once they have your login credentials, they repeatedly trigger MFA push notifications to your phone or device. These alerts usually ask you to approve a login attempt. The attacker’s goal is to bombard you with so many notifications that you eventually tap “Approve” just to make them stop. And that one approval is all they need.
The FBI’s IC3 unit warned about this tactic used in the Scattered Spider attacks.
During an attack, you might see a rapid stream of authentication requests—sometimes dozens, even hundreds. Scammers hope it’s late at night or during a busy moment when you’re more likely to slip up and accept one. Some even escalate by sending a message pretending to be IT support, urging you to verify the login to “fix an issue.”
If someone falls for a push bombing attack, the consequences can be serious. That single approved notification grants the attacker full access to the account—whether it’s email, banking, work systems, cloud storage, or anything else tied to MFA. From there, they can steal data, lock you out, or use your account to target others.

The best protection is never approving unexpected login requests and switching to more secure MFA options like passkeys or authenticator apps. Staying alert can stop push bombers from pushing you.
