MFA 피로 공격 (MFA fatigue)
Definition
Flooding a user with MFA push prompts until they approve one by accident.
For executives (CEO·CISO)
It targets human fatigue, not technology — enabling MFA is not the end. Commonly missed: switch to number-matching / phishing-resistant MFA and train staff to "deny and report any unexpected MFA prompt."
