Notes
Seul root peut changer la propriété vers un uid arbitraire; un non-root ne peut changer le groupe que vers un groupe dont il est membre. macOS efface les bits setuid et setgid après un chown réussi pour atténuer l'élévation de privilèges.
Détection
ES émet ES_EVENT_TYPE_NOTIFY_SETOWNER. syscall::chown:entry en DTrace.
