Issue/Introduction
Is monitoring of VNC traffic possible?
Resolution
In short: No, you can not monitor VNC traffic.
VNC uses an RFB Protocol (Remote Frame Buffer) to display information by rendering the screen on the remote desktop. The communication essentially consists of the API call made to the graphic driver and this can not be detected. In addition, the communication can be encrypted based on which RFB implementation is used. Encrypted traffic can not be decrypted.
