Authentication Tracing - Instructions
Purpose
This skill performs forensic analysis of Entra ID authentication flows to determine whether anomalous sign-ins represent:
- Legitimate activity (VPN usage, user travel, mobile carrier routing)
- Token theft/credential compromise (stolen refresh tokens, session hijacking)
The key distinction is whether the user actively performed MFA at a suspicious location or if the authentication used a refresh token from a prior session.
