Detection Logic

detection:
    selection_img:
        - ParentImage|endswith: '\cmd.exe'
        - Image|endswith: '\cmd.exe'
        - OriginalFileName: 'cmd.exe'
    selection_flags:
        - ParentCommandLine|contains:
              - '/c'
              - '/k'
              - '/r'
        - CommandLine|contains:
              - '/c'
              - '/k'
              - '/r'
    selection_path_traversal:
        - ParentCommandLine: '/../../'
        - CommandLine|contains: '/../../'
    filter_java:
        CommandLine|contains: '\Tasktop\keycloak\bin\/../../jre\bin\java'
    condition: all of selection_* and not 1 of filter_*
