Executive Summary

This article highlights a critical authentication vulnerability where stolen credentials can render Multi-Factor Authentication (MFA) ineffective. Attackers leverage phishing relays and session hijacking techniques to bypass traditional MFA systems that verify sessions rather than actual users. The threat enables adversaries to maintain persistent access even when organizations have implemented MFA controls. The article presents Token's wearable biometric authentication as a defensive solution that verifies the user identity itself rather than relying on session tokens. Organizations should consider phishing-resistant authentication methods and user-verification approaches to mitigate these bypass techniques.

Summary

Stolen credentials turn authentication systems into the attack surface. Token shows how wearable biometric authentication verifies the user—not the session—blocking phishing relays and MFA bypass. [...]
