UltraVNC w/ DSM plugin detection

A remote control service is running on this port. Description : UltraVNC seems to be running on the remote port. Upon connection, the remote service on this port always sends the same 12 pseudo-random bytes. It is probably UltraVNC with the DSM encryption plugin. This plugin tunnels the RFB protocol into a RC4 encrypted stream.
If this service is not needed, disable it or filter incoming traffic to this port.
