Invoke-Obfuscation VAR+ Launcher via Service Creation
Detects the creation of a new Windows service where the ImagePath contains highly obfuscated PowerShell commands. Specifically, it looks for 'cmd' executing a 'set' command to define an environment variable, followed by PowerShell execution with the '-f' format operator, which is characteristic of Invoke-Obfuscation's VAR+ launcher technique. This method uses environment variables and string manipulation to hide malicious PowerShell code.
