New Windows Service Installed via Remote SMB
This rule detects the remote installation of a new Windows service over SMB (Server Message Block) protocol. It specifically looks for TCP traffic on port 445 (SMB) directed to the home network, containing the strings "CreateService" and "svcctl" (case-insensitive). This combination indicates an attempt to create a new service remotely, which can be a method for persistence or privilege escalation by attackers.
