MFA is essential, but it only proves control of authenticators at a point in time, not that the person is truly the legitimate identity. Attackers can exploit enrollment, recovery, help desks, session theft, and authenticator replacement to pass MFA while remaining impostors. #NISTDigitalIdentityGuidelines #IdentityThreatDetection #SessionHijacking
Keypoints
- Authentication is not the same as identity verification.
- Attackers can pass MFA by abusing recovery, enrollment, and support processes.
- Phishing-resistant MFA still depends on how authenticators are bound and replaced.
- Successful login does not mean an identity remains trustworthy after authentication.
- Identity confidence should be established, monitored, and re-validated when risk changes.
