This rule detects the installation of the Azure Hybrid Connection Manager service, which is associated with enabling remote code execution capabilities from Azure Functions. The rule focuses on monitoring Windows Registry events for entries that relate to this specific service. It looks for changes in the Registry that include the service name and any related executables. If either of the two defined selection conditions is met—namely, detecting the presence of 'HybridConnectionManager' in the path to services or the execution of 'Microsoft.HybridConnectionManager.Listener.exe'—the alert will fire. The rule is particularly relevant in scenarios where unauthorized installations of this service might facilitate exploitation vectors for attackers, effectively allowing remote code execution from Azure. It is crucial for organizations to monitor such installations as they could indicate a potential security breach or misconfiguration in their Azure environments.
