Now with this video I'd like to show you how to disconnect multiple devices or all devices from one

network or disconnect all devices from a number of networks so basically disconnect any one around you

from connecting to any network around you.

You can do all of that using the same tool and use the same command really.

The only thing is you'll need to run the command multiple times.

That's the whole idea behind it.

So in the previous video we targeted the Windows machine and the command we used was this.

So we did a replay ngi.

We told it to do the authentication.

A large number of packets we put the MAC address of the target network and then we put the MAC address

of the target computer.

And this was the MAC address of the windows computer.

So you can run that command.

And then if you want to target another computer all you have to do is just run the same command again

but specify the MAC address of that second computer so you can do that in a separate window or you can

split the terminal here you can split it horizontally or vertically and then run the command in a separate

command prompt.

Alternatively because this can get really messy if you're target more than one computer.

So if you want to target three or four or five computers you can run the command in the background and

I'm going to show you how to do that because first of all it's a really handy skill to learn because

you can use this with all Linux commands.

And it's also much better to do it with this attack instead of using it in different windows.

So to run this attack all we have to do is put the and character right here that will tell the Bysshe

or Linux to run this in the background to run this particular command in the background.

But we still have one problem because if you remember in the previous video when we ran this command

the result of replay ngi kept showing up on screen so the screen kept getting filled with the result

of airplay and.

So even if we run this in the background our terminal screen will still get full of the output of airplay

ngi.

So what we're going to do is we're going to redirect that output by saying to Dev No.

And again we're going to put the character to tell.

I want to do all of this in the background don't show it to me at all.

I want to see another command prompt to run another command.

So again we're using the same command that we did before.

So that didn't change at all.

We added the and character at the end to run the command in the background.

And you can do that with all Linux commands.

Not only with this command then we are told that we also want you to redirect the output of a replay

N-G to nowhere.

I don't want to see it on my screen.

And we finished again with an add character to say I want to do all of this in the background.

Don't show me anything but keep this process running in a different thread in the background.

So when I hit Enter now I won't see any output.

The command will be running in the background and then I'll be able to run another command and disconnect

another computer.

So before I run this command I'm going to go to my Windows machine here.

And as you can see I'm connected again right here to my network to UPC PC and if I search for anything

here you can see that I have internet connection.

So this is going to be my first target and my second target is going to be this OS X machine.

So I'm just going to show you its MAC address.

I'm going to do if Campag

and this is the MAC address of the OS X machine.

So it ends up with eight.

And if we come here we can see it.

It's right here.

So I'm actually going to copy it.

And I'm going to run this command and you'll see when I hit enter or once anything on screen I'll just

see a prompt telling me that this command is running and that's it.

I want see the same output that we got in previous video.

So I'm going to hit enter and as you can see all I did is I just got the job id which is number one

so this is the number of jobs that's running in the background of this particular terminal window.

So if I do jobs you'll see that I have one job running and that's airplay ngi and I can see the whole

command that I used.

So this is the authenticating the Windows machine at the moment.

And we'll go to it in a second.

I just want to do the OS X machine and then we check out the two machines and see how both of them lost

their connection.

So I'm going to run the exact same command again.

Instead of the MAC address of the windows I'm going to put the MAC address of the OS X machine

and I'm going to hit enter.

And you can see that I have another job added to the background and this one has an idea of number two.

So if I do jobs you can see that I have two jobs running there the exact same command target in the

exact same network.

But one of them is targeting the Windows machine and the other is targeting my Mac OS X machine.

So we go to the Windows machine and we look at the bottom and sure enough it doesn't have internet connection

right here.

And even if I try to go to a web website just to confirm that

we can see that it's completely disconnected from its network.

Now I'm going to go to the OS X machine and try to open the browser right here.

Let's try to go to Google.

And as you can see there is nothing shown up.

We can connect to Google or we can't go to any Web site we want.

We literally have no connection to the network.

So we managed to do that by running a display ngi twice on those two specific devices.

So if you wanted to target two devices three devices again run the command three times you want to target

five devices around at five times.

This can be very useful if you wanted to connect a number of devices but not all devices.

So you wanted to target two or three devices and keep your own device or a certain device connected

for a certain reason.

Now these commands are still running in the background.

So if you can stop them based on the idea right here so you can see that the first command has an idea

of number one.

And the second command has an idea of number two so you can stop all of them by saying kill all

a replay ngi

and that will stop all airplay Engy processes including the two of them.

But if you wanted to stop one of them at a time then you're going to do kill percentage number one.

And that will only kill the first process.

So that's only going to kill our windows machine process.

And if we do jobs now you can see that the first process got terminated.

But the second one is still running now I'm going to do the second command the kill all command just

to show it to you.

And this command will kill all airplay and instances.

So if we do kill all

and then do jobs you'll see that the second process also got terminated.

So it could have killed that with percentage too.

Or you can do this method if you wanted to just stop the attack and kill all the instances that this

connected devices do.
