This rule detects potentially malicious, automated enumeration of Microsoft Graph API endpoints. It monitors for high volumes of requests (>= 8 within a 15-minute window) that utilize multiple OData pagination, filtering, and search parameters such as $top, $skip, $skiptoken, $count, /delta, and /search. Such activity is often indicative of automated reconnaissance, data scraping, or unauthorized bulk enumeration of cloud directory resources.
