A: Run sudo apt update && sudo apt install -y kali-desktop-xfce in a terminal session to install the new Kali Linux Xfce environment. xubuntu-desktop comes with more applications but obviously takes up more room too. This happened due to the conflict of two display managers the gdm3 that comes pre-installed with the basic installation of ubuntu and the lightdm that comes with the xfce4. After saving the text file and restarting the VNC Server, we can be assured that the service will now be running on port 4455.

Since we are on our Kali Linux Machine, we can use it to perform a port scan on our VNC server to see how the running service will look when an attacker tries to do the same. We are now just left with the task to run the VNC Server on our Ubuntu machine. Upon starting Kali Linux up, certain things (Windows/buttons or text/font) may appear smaller than expected. To demonstrate we will be capturing the traffic from the authentication that happens between the Windows Machine and Ubuntu Server. It was 1234. We used Wireshark for capturing the network traffic packets. If the device is used to access another machine through TightVNC the credentials can be compromised.

This will contain the Desktop environment that the VNC should use when connecting to the server. It is located at /usr/bin/vncserver. To test this hypothesis, we get back to the Kali Linux Machine, here we again performed the port scan using Nmap and we could see that indeed the service is detected on the new port and it is possible to connect to VNC at 4455.

Since we saw how easy it was to first enumerate the service and then perform a Bruteforce attack that could result in the compromise of our machine, we can think of a method that will help us. We performed the Nmap script scan and we can see that again the Protocol Version is 3.8 but now we also see that the authentication mechanism that is in place is the VNC Authentication, which we will get into later in this article.
