selection_img:
    - OriginalFileName:
          - 'wscript.exe'
          - 'cscript.exe'
    - Image|endswith:
          - '\wscript.exe'
          - '\cscript.exe'
selection_cli:
    CommandLine|contains:
        - '.js'
        - '.jse'
        - '.vba'
        - '.vbe'
        - '.vbs'
        - '.wsf'
        - '.wsh'
