Abuse Info

No additional abuse is necessary to traverse this edge. The abuse primitive is captured on the edge leading to this FIC. Once a token has been obtained from the FIC’s trusted issuer, it can be exchanged at the Microsoft identity platform token endpoint for an access token authenticating as the target App Registration. From there, follow the AZRunsAs edge to understand what Service Principal context, and associated permissions, the attacker gains.
