\"What<\/span><\/p>\n

Multi-factor authentication (MFA) adds an extra layer of security after entering your password, such as approving a push notification on your phone. Cybercriminals bypass this through MFA fatigue attacks, also known as MFA push spamming, MFA exhaustion attack, MFA bombardment attack, or push notification authentication attack.\u00a0<\/span><\/p>\n

In these attacks, the attacker already has your password from a leak or phishing, and then floods you with repeated login requests or notifications, hoping you’ll get frustrated and approve one to make them stop. You’ll know it’s happening if you receive multiple unexpected MFA prompts in a short time when you haven’t tried to log in anywhere.\u00a0<\/span><\/p>\n

For MFA fatigue protection, always deny any request you didn’t start yourself. Report suspicious activity immediately. To prevent MFA fatigue attacks, use MFA fatigue security best practices. Switch to hardware security keys or passkeys. These can’t be spammed like push notifications.<\/span><\/p>\n

What Is an MFA Fatigue Attack?<\/b><\/h2>\n

An MFA fatigue attack is a <\/span>social engineering<\/span><\/a> trick. Hackers spam you with tons of MFA requests, usually push notifications. They keep going until you get annoyed or tired and approve one by mistake. The goal is to trick you into giving them access to your account.<\/span><\/p>\n

This is also called a push notification attack cybersecurity threat. It targets those simple “Approve” or “Deny” prompts on your phone. It doesn’t need complex code. It just exploits how people hate endless notifications.<\/span><\/p>\n

These attacks have been around for a few years, but have become more common recently. A famous example is the 2022 Uber breach, where hackers used MFA fatigue to break in. Cisco faced a similar attack in 2022.<\/span><\/p>\n

\u00a0In 2024, Apple users were hit with MFA fatigue attacks involving endless password reset prompts. No one is safe\u2014not big companies or regular people, especially if credentials leak online.<\/span><\/p>\n
