Detects instances where an unprivileged user executes commands like 'ls -l' or 'stat' on the Parallels dispatcher Unix socket (/var/run/prl_disp_service.socket) specifically when it is world-writable (mode 0777). This behavior indicates an adversary attempting to verify if they can exploit the insecure socket permissions to interact with or hijack the Parallels dispatcher service.
