High-Risk OAuth App Consent and Service Principal Operations via Proxy Infrastructure
This rule detects suspicious activities related to OAuth application consent and service principal operations originating from proxy infrastructure. Specifically, it looks for actions such as adding service principal credentials, granting OAuth2Permission, consenting to applications, adding delegated permission grants, or adding new service principals/applications, where the initiating IP address is identified as belonging to a proxy service. This combination of activities and source IP can indicate an adversary attempting to establish persistence or escalate privileges within an Azure AD environment.
