This advisory reviews the Change Healthcare 2024 data breach to highlight how lack of multi-factor authentication (MFA) enabled credential-based access, explains MFA types and newer approaches (adaptive and passwordless), calls out weaknesses such as MFA fatigue/prompt‑bombing, and recommends deploying phishing‑resistant MFA (FIDO2), identity telemetry, and security awareness to reduce human and credential risk.
