MFA fatigue attacks exploit human psychology, and the very tools meant to enhance security. Learn how to protect your organization from these attacks and keep your data safe.

When it comes to cybersecurity, the evolution of threats is as dynamic as the technologies designed to thwart them. Among the more insidious developments are the cyberattacks designed to undermine multifactor authentication (MFA). MFA fatigue attacks – also known as MFA bombing or prompt spamming – exploit human psychology and the very tools meant to enhance security. Understanding these attacks and implementing robust countermeasures is crucial for protecting systems from data breaches.

MFA is a strong access management tool designed to prevent data breaches by requiring multiple proofs of digital identity. Usually, MFA is secure and simple, with users confirming a login attempt with further acknowledgements such as approving a push notification on their phone. Cybercriminals exploit this safeguard through MFA fatigue attacks. In this social engineering tactic, attackers use stolen credentials to attempt a login, triggering an MFA prompt. The attackers then commence MFA bombing: bombarding a user's authenticator app or mobile device with calls or push notifications. This barrage of requests is designed to wear down the user's vigilance. Eventually, they might accept one, either to stop the notifications or because they've been deceived by the attacker into thinking the request is legitimate.

Organizations can follow a few simple steps to combat MFA fatigue attacks and MFA bombing and ensure that MFA provides the robust security it’s designed to provide.
