Uncommon Service Installation Image Path
This rule detects the creation of new Windows services with suspicious or uncommon image paths. It specifically looks for paths containing references to named pipes, common temporary directories like `Users\Public\` or `Windows\Temp\`, or image paths that include patterns indicative of encoded PowerShell commands (e.g., `-e` followed by specific base64 encoded strings). This behavior is often associated with adversaries establishing persistence or escalating privileges by creating malicious services.
