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. But enough about the theory of it, let’s get into it. I prepared a Metasploitable2 machine that includes a dated version of the VNC Server. Using port-forwarding, the VNC server can be configured to only accept connections on the remote desktop ports from itself and not any external connections. If that's not an option, definitely use a strong random password and ensure that your communication to the server is encrypted. If you password is sent in plain-text, it can be intercepted. VNC server password that are saved on the computer registry or ini file is encrypted but it can be easily cracked and decrypted for password recovery purposes. How about using an encryption key derrived from a password that is communicated over the phone: User(A),who runs SC server, is prompted for a password 10 chars long. SC creates an encryption key based on that password. (Or SC server generates a password on they fly and presents it to the User A) User A tells Viewer (B) what the password is.

We have customers using VNC in secure environments including DoD labs around the country, and in those cases the issues of security have been addressed to everyone’s satisfaction.

VNC Server Security

Password

Taking things a step further, the server can be configured to only accept connections via SSH (the secure shell). If the server is configured to accept connections only from localhost (127.0.0.1), which is unspoofable because it is not routable, the only connection the server will accept is one made via the SSH tunnel, thus creating a completely secure connection.

Note: To read about making an SSH connection through the Connection List in Eggplant Functional, see Opening Secure Connections.

The Network configuration can also be set up in a secure manner, outside of the VNC server:
