This rule detects API requests to the Microsoft Graph search/query endpoint. This endpoint can be used by adversaries to enumerate items such as SharePoint site URLs, which is a common technique used by tools like GraphRunner's Get-SharePointSiteURLs function. The detection specifically looks for successful POST requests to 'https://graph.microsoft.com/v1.0/search/query'.
