    You can verify file content here

    It does not present in WordPress 5.0.4 (which is old and you should not be using it, even if you are stuck with 5.0.x branch)
    But its indeed present in WP 5.2.x and newer

    During the execution of the server side scan, the plug-in check WordPress core directories on existence of alien files as well as verify core files integrity comparing core files hashes with information retrieved from WordPress API.

    Every alien file or modified core file reported as suspicious in the scan report.
