Where Multi-Factor Authentication Stops and Credential Abuse Starts
Summary
While multi-factor authentication (MFA) is a crucial security measure, its effectiveness can be undermined by incomplete implementation in Windows environments. Attackers can still gain access using valid credentials if MFA is not universally enforced across all applications and services.
IFF Assessment
This article highlights a common gap in MFA implementation, indicating that attackers can still exploit credential abuse even when MFA is present, posing an ongoing threat to defenders.
Defender Context
Defenders need to ensure that MFA is comprehensively enforced across all critical applications and services, not just the primary login. Organizations should audit their identity provider configurations to identify and close any gaps where credential abuse remains possible despite MFA being deployed.
