For all you school rebels out there..

35 posts in this topic

So, it's my freshmen year in highschool, and within' the first week of starting I already got accepted to be a Teacher Assistant with the Tech ppl at my school.

Anyways, while they had me do a few things on the computers at school, they made me install something called Vision, if you haven't heard of it then I will explain:

Vision is a tool such as Radmin that allows remote connection to a PC for screen viewing, etc.

A teacher can control an entire classroom of computers with this.

http://www.genovalogic.com for more info/downloads.

So, the story goes like this:

I was in class doing a project and the teacher was looking at MY screen only (like every day) and starts yelling across the room what im typing and im doing it wrong, and that just got me mad. So, I made a quick tool that will delete Vision from a PC.

Don't use this if your going to do it on every PC and be like "omg l33t h4x0r im so cool", it's just for anyone that doesn't want the damn teachers to look at your screen :angry:

I made it in VB:

so if it delets this program, won't the teacher notice, that it is gone and that he cannot acess your computer's screen anymore?

Agreed, Nice program but overall worthless. You'll be in heaps o' trouble when they find out you deleted this program and distributed the deleter.

i think its cool, i dont think it would be smart to use, as it seems schools really crack down on things like this. but i think the tool is fucking cool

you should post your source code for this.

Agreed. This is cool, as long as you don't get caught. Nothing pisses me off more than people spying on me. Just make sure you can cover your tracks.

So, how does it work?

I'm assuming that it looks at the Task Manager and if it notices a certain process (Vision) to kill the process. It would be nice to view the source though.

I tried doing that for DameWare mini remote, but it just re-launches after you kill it. Maybe there's another process I haven't spotted that keeps it alive.

There is an easier way to disable the Master Solutions Vision Client, and at the same time keep the files intact. I'm assuming XP is blocking your permission to access the hard drive outside of your My Docs folder. Navigate to My Documents, to My Pictures then to Sample Pictures. Then, in Windows Explorer Hit the "UP LEVEL" folder button till your in the root directory. From here navigate your way to Program Files/Master Solutions/Vision. Open up the config tool and highlight (Do not start before login). From this point forward, you can right click the vision task icon and select close.

Cheers :-)

Well, for one, teachers are plain stupid in high school. See, when they open vision they get a list of PC's, they hardly even check to see which do not work, and if it does get removed and they noticed, all I say is that the tech ppl installed a new copy a few days ago.

I have only made it for Win2K so far (for file paths, I uses C:\WinNT, but I will make it for Win2K and XP soon)

As for the source code, I will probably post sometime soon.

BrakeDanceJ: heh, I did not know about that, but, doubtfully that will work on our computers. Our school does not use DeepFreeze or anything, they use a script and it disallows any use of .exe files etc. only ones on a certain list for certain file paths (i.e. Microsoft Word, IE, Mozilla, etc.)

That may work for some, but not for us. Instead, I just burn this to a CD and use auto-run and it works well for me, dont know why they haven't stopped the use of CD's, prob. for installers etc.

Also, I have admin, and can login, but when you login as admin your screen changes and teachers will notice :-/

A better and far more challenging implementation would allow you to provide the teachers with a static fake-screen: regardless of what you are doing, the far-end can only see a pre-generated screenshot.. something like an innocent google search or the desktop background with a few harmless looking tabs in the taskbar.

People generally trust what machines are telling them until they have had a reason not to. <_<-_-

I completely agree.

Or if you want to make it a bit more convincing, make a loop of some innocent screen activity and play it back (I have no idea how on earth you would manage that)

Make a video of it then play it back using a control.

But, talking about getting in trouble, you even touch a teachers computer and your pretty much owned.

Has anyone reverse-engineered the Vision client protocol yet? If so blast me the documentation, and ill get to work.

Heh, nice program! So basically Vision is a backdoor screen capture program, correct? Do you know what port the server runs on and can one download the client application and monitor users like the teacher does? It would be funny to install a server on a teachers computer and have them monitor you while your monitoring them! :P

why do you guys make things harder then they should be? Why not just arp poison another computer on the lab =p so when the teacher runs the program they'll be looking at the other computer and thinking its you? or when your teacher says hey why cant i view your computer. you just type cmd > shutdown -i and shut down the teachers computer. Nice program none the less, makes me want to start programming again.

Last time we tried to ARP poison at school, the net admin detected it and went on a little hunt.

Hey,

I figured out how to shutdown Dameware mini remote....


net stop dntus26
net stop dwmrcs

Maybe it'd be easier to shutdown spyware like this rather than using code and arp spoofing and such...

If they come over and ask why they can't see your PC, you just say 'oh, it went funny and crashed, maybe I need to reboot', then just reboot and it'll start again. The teacher will think that the software just crashed or something.

viva la resistance! :)

K, maybe instead of deleting it, just kill it's process and route any incomming connections on Vision's port to someone else's computer, so the teacher will see his screen instead of yours, and assuming Vision only supports one connection at a time, will not be able to connect to that computer.

Here's a little prog I made a couple of years back. It simply does exactly as described above. (Not that I have tested it with Vision, but it can route just about any type of tcp connection I have tested so far.)

I think I still have the source code lying around too, if you want to have a peek.
