Detection Logic

detection:
    selection:
        ParentImage|endswith: '\GoogleUpdate.exe'
    filter_main_known_legit:
        # Some other legit child process might exist. It's better to make a baseline before running this in production
        - Image|contains: '\Google' # Example: GoogleUpdate.exe, GoogleCrashHandler.exe, GoogleUpdateComRegisterShell64.exe
        - Image|endswith:
              - '\setup.exe'
              - 'chrome_updater.exe'
              - 'chrome_installer.exe'
    filter_main_image_null:
        Image: null
    condition: selection and not 1 of filter_main_*
