Hi everyone, I'm currently having a special problem on my office LAN: someone is entering various PCs but the weird thing is that it appears that this person is actually seeing and controlling the other computer's video and mouse pointer. As far as I know, you can use a RAT to obtain plenty information and data from other PC, but I haven't heard of any hack which enables you to see and control remote PCs without any visible trace of "something" wrong natively. How could it be possible? How could I trace that hack? How could I avoid it and protect from it? Thanks in advance.
