This skill is designed for security professionals who need to detect and analyze suspicious OAuth application consent grants within Azure Active Directory (Azure AD) or Microsoft Entra ID. By leveraging the Microsoft Graph API, the skill systematically enumerates OAuth2 permission grants and scrutinizes application permissions to identify any that may be excessively broad or potentially harmful. It also reviews directory audit logs to track consent events, allowing for a comprehensive assessment of application risk based on publisher verification status and the scope of permissions granted.

The skill operates by first authenticating to Microsoft Graph using the MSAL client credentials flow. Once authenticated, it retrieves all OAuth2 permission grants and lists service principals along with their assigned permissions. By querying the directory audit logs for consent events, it flags applications that request high-risk permissions—such as Mail.Read or Files.ReadWrite.All—and checks the verification status of each application publisher. This structured approach not only helps in identifying illicit consent grant attacks but also provides a risk report with remediation recommendations to enhance security posture.

This tool is particularly useful for security operations center (SOC) analysts, incident response teams, and organizations looking to bolster their cloud security measures. It can be employed during security investigations, to build detection rules, or to validate existing security monitoring coverage against known attack techniques. By automating the detection of risky consent grants, it saves time and improves the accuracy of threat assessments in cloud environments.

Overall, this skill is an essential addition for any team focused on maintaining the integrity of their Azure AD or Microsoft Entra ID environments, ensuring that they can proactively manage and mitigate the risks associated with OAuth application permissions.
