What it detects
This rule detects enumeration of users groups and service principals through the legacy Azure AD Graph API versions 1.5 and 1.6 from scripting user agents such as python aiohttp curl and Go-http-client as described in Elastic research on AAD Graph activity logs. Programmatic access to the deprecated Graph endpoint frequently reflects tenant reconnaissance rather than sanctioned application traffic.
