Zero config VNC server for those PCs you have to support

The EchoVNC folks have released V1.36 of InstantVNC. Based on UltraVNC, it’s a VNC server that you can have those folks whose PCs you have to support download and install.

The above-linked article is derived from this weblog entry, which describes the attack and how to disable it. It all comes down to creating a new entry in your registry (you should already know how to do this) by putting the following into a text file and importing it into REGEDIT (note that everything between the “[” and the “]” should be on one line):

@="@SYS:DoesNotExist"
