Hunting query that identifies Entra ID application registrations and updates where one or more redirect URIs (reply URLs) point to an external domain that is not a trusted Microsoft endpoint, localhost, or a standard OAuth out-of-band value. An attacker who can register or modify an application may add an attacker-controlled redirect URI to intercept OAuth authorization codes and exchange them for access tokens without user interaction after consent is granted. Trusted prefixes excluded by this
