Internet-Security.com TCP port 5907 details

TCP port 5907 is used by VNC implementations (RFB protocol) as the listener for display :7 (port 5900 + display number).
Real-world software that will listen on 5907 when configured for display :7 includes RealVNC Server, TightVNC, UltraVNC, TigerVNC (Xvnc/x11vnc), and Apple Remote Desktop in VNC-compatible mode.
In Linux/Unix deployments, vncserver instances (e.g., TigerVNC) commonly expose sessions on 5907 when started as display :7.
This port is frequently scanned and brute-forced when exposed to the internet, because misconfigured or weakly protected VNC services are common attack targets.
