An MFA Fatigue attack is when a threat actor runs a script that attempts to log in with stolen credentials over and over, causing what feels like an endless stream of MFA push requests to be sent to the account’s owner’s mobile device. The goal is to keep this up, day and night, to break down the target’s cybersecurity posture and inflict a sense of “fatigue” regarding these MFA prompts.
