AzureHound Discovery Activity Detection
This rule detects activity related to AzureHound, a BloodHound data collector specifically designed for Microsoft Azure environments. It identifies AzureHound's presence by looking for its default 'User-Agent' string in Azure sign-in logs after a successful authentication (ResultType: 0). This indicates that an authenticated user or service principal is using AzureHound to enumerate Azure resources, which is often a precursor to further reconnaissance or privilege escalation within a cloud environment.
