Detects the creation of new Windows services using either the 'sc.exe' command-line utility or the PowerShell 'New-Service' cmdlet. The rule specifically looks for suspicious binary paths associated with the newly created service, including common scripting interpreters (powershell, wscript, cscript, cmd), system binaries (svchost, dllhost, rundll32), and suspicious user-writable directories (Public, Downloads, Desktop, Startup, Temp). This activity is often indicative of persistence or privilege escalation attempts by adversaries.

Detects the installation of 'NalDrv' or 'PROCEXP152' services by monitoring registry key modifications. These services are associated with the 'Ghost-In-The-Logs' tool, which leverages KDU for defense evasion. The rule specifically looks for the creation of these service ImagePath registry values in non-system32 folders, filtering out legitimate instances of tools like procexp and procmon.
