Take control of another computer

I am trying to demonstrate how you can theoretically get control of another persons computer.

Here's my demonstration setup:
-2 computers.
-Both connected on the same router (LAN).
-Control over the router (if I need to open ports etc)
-Both running Windows 7
-Have admin account credentials for both machines
-Both computers are on and logged in (or can be in logged out state if need be).

How would I go about getting control of one computer from the other without the other computer knowing? (I.e no popups or anything like that - just straight control). Is this possible without the need for extra software?

Thanks.

You would only be able to do this using your criteria in one of two ways:

First:

1) Apply the concurrent RDC patch on each machine (sourced from the missingremote website or I can upload it for you, the one i have covers all windows versions 64 and 32bit and is simple to apply)

or

2) Install a Windows Server version of the OS which has concurrent RDC enabled by default.

After either of the above has been done you can simple Start > Run > mstsc to start remote desktop and punch in the other computer's name and connect to the currently logged in account.

The benefit in the Patching option is that you can opt to patch using the password free method so you can RDC into the machine on an account that doesn't have a password too.

You will then log into the active account whether it's logged in or not and be able to take full control as if you were that user but you won't be sharing the same instance of the logon so you won't see what they see in a running app for example, it's just a concurrent session.

If you wanted desktop instance sharing type remote then you need to use either Remote Assistance or LogMeIn/Teamviewer or something like that.

There may be alternatives someone else can recommend but that's the simples of it :p
 
You could use VNC (which wont prompt the user at all) and gives you complete remote desktop connection.

I'm not sure if it works on Windows 7 yet, in which case take a look at Ultra VNC
http://www.uvnc.com/

You'd need to install the VNC server on the machine you want to take control of, and make sure Windows Firewall (if on) and your router lets you use port 5900 on UDP and TCP.

Then from your machine you just run VNC, type the IP address of the machine you want to connect to and enter the password.

You've then got control of that computer :)

Team Viewer or GoToAssist will do the same thing, but will prompt the user that someone wants to connect and you'd need to use the password and ID that would appear on their machine first.

Using VNC, so long as the VNC server is setup and running on that machine, you just connect and take control.
 
I've just reread your OP, I take it that you basically mean hacking into a machine on the network and taking control of it? Without the user noticing, or you physically being at the other machine?

If that's the case I doubt we would be able to discuss this here. Not that I wouldn't like to know myself of course ;)

All the ways we've mentioned so far, means you would need to initially setup some software on the machine you want to take control of... you'd physically need to be sat at that computer for the initial setup... but after that you are free to connect over the network or even the Internet.
 
Is RealVNC usable for desktop sharing though? as in you can see what the other machine sees onscreen instead of just concurrent sessions on the same account (which the RDC patch is and server versions of Windows using RDC)?
 
What do you mean by take control without the computer knowing... computers dont care who controls them! someone sitting in front of it will see the mouse moving about without them moving it!

Or do you mean access the machine and view files and folders without the other person knowing?

Could you upload this for me please? Is there anyway to uninstall/reverse this without a reinstall?

It's basically for a demonstrating that it can actually be done.

I have physical access to the machine (i own both machines) so will be doing the concurrent patch thingy if it isn't possible to do with a standard install....my only question is, when I have finished, will I be able to uninstall the patch as I see that as a potential security flaw.

I take it that there is no way to do it with just the standard Windows 7 install (without installing anything). I don't care if the user can see the mouse moving etc....(if not with the standard install - what if i change a few settings?)

Lemme know - and thanks for the info so far.

If you have physical access and a known administrator account on both machines, then there isn't really much to demonstrate in terms of security flaws if that's what you're after. Things like default shares are much, much tighter on Vista/W7 than XP and you have to explicitly enable remote connections.

As mentioned above, you could easily install VNC and then take control of the computer - but the only thing this demonstrates is that the computer is working normally.
