How do I kill a VNC server session?
To stop the VNC server, use the vncserver command with a -kill option. A server number is provided as an argument. Killing the VNC server closes all windows and stops processes that were running in that VNC session.
Is VNC easy to hack?
VNC usually runs as a service, so it’s mostly not even seen by the user. Even if there is a password on it, it is often times only a password without a username, so it’s relatively “easy” to crack if you already have collected some information on the company.

An attacker is on the same network with the VNC server and attacks it to gain the ability to execute code on the server with the server’s privileges. A user connects to an attacker’s ‘server’ using a VNC client and the attacker exploits vulnerabilities in the client to attack the user and execute code on the user’s machine.
How are vulnerabilities in a VNC client exploited?
A user connects to an attacker’s ‘server’ using a VNC client and the attacker exploits vulnerabilities in the client to attack the user and execute code on the user’s machine. Attackers would without doubt prefer remote code execution on the server. However, most vulnerabilities are found in the system’s client component.
