1
00:00:00,360 --> 00:00:06,750
Now with this video I'd like to show you how to disconnect multiple devices or all devices from one
2
00:00:06,750 --> 00:00:13,200
network or disconnect all devices from a number of networks so basically disconnect any one around you
3
00:00:13,200 --> 00:00:15,880
from connecting to any network around you.
4
00:00:15,960 --> 00:00:20,100
You can do all of that using the same tool and use the same command really.
5
00:00:20,280 --> 00:00:23,700
The only thing is you'll need to run the command multiple times.
6
00:00:23,700 --> 00:00:26,620
That's the whole idea behind it.
7
00:00:26,630 --> 00:00:32,240
So in the previous video we targeted the Windows machine and the command we used was this.
8
00:00:32,240 --> 00:00:34,090
So we did a replay ngi.
9
00:00:34,160 --> 00:00:36,350
We told it to do the authentication.
10
00:00:36,350 --> 00:00:42,680
A large number of packets we put the MAC address of the target network and then we put the MAC address
11
00:00:42,680 --> 00:00:43,870
of the target computer.
12
00:00:43,870 --> 00:00:46,660
And this was the MAC address of the windows computer.
13
00:00:46,790 --> 00:00:48,830
So you can run that command.
14
00:00:49,190 --> 00:00:54,440
And then if you want to target another computer all you have to do is just run the same command again
15
00:00:54,680 --> 00:01:00,530
but specify the MAC address of that second computer so you can do that in a separate window or you can
16
00:01:00,530 --> 00:01:07,280
split the terminal here you can split it horizontally or vertically and then run the command in a separate
17
00:01:07,280 --> 00:01:08,670
command prompt.
18
00:01:08,690 --> 00:01:13,460
Alternatively because this can get really messy if you're target more than one computer.
19
00:01:13,490 --> 00:01:20,150
So if you want to target three or four or five computers you can run the command in the background and
20
00:01:20,150 --> 00:01:24,440
I'm going to show you how to do that because first of all it's a really handy skill to learn because
21
00:01:24,440 --> 00:01:26,850
you can use this with all Linux commands.
22
00:01:27,080 --> 00:01:32,160
And it's also much better to do it with this attack instead of using it in different windows.
23
00:01:32,210 --> 00:01:41,380
So to run this attack all we have to do is put the and character right here that will tell the Bysshe
24
00:01:41,470 --> 00:01:46,460
or Linux to run this in the background to run this particular command in the background.
25
00:01:46,540 --> 00:01:51,640
But we still have one problem because if you remember in the previous video when we ran this command
26
00:01:52,120 --> 00:01:58,600
the result of replay ngi kept showing up on screen so the screen kept getting filled with the result
27
00:01:58,630 --> 00:02:00,040
of airplay and.
28
00:02:00,160 --> 00:02:06,490
So even if we run this in the background our terminal screen will still get full of the output of airplay
29
00:02:06,490 --> 00:02:07,300
ngi.
30
00:02:07,330 --> 00:02:15,920
So what we're going to do is we're going to redirect that output by saying to Dev No.
31
00:02:16,290 --> 00:02:19,080
And again we're going to put the character to tell.
32
00:02:19,080 --> 00:02:23,430
I want to do all of this in the background don't show it to me at all.
33
00:02:23,430 --> 00:02:27,510
I want to see another command prompt to run another command.
34
00:02:27,510 --> 00:02:30,750
So again we're using the same command that we did before.
35
00:02:30,780 --> 00:02:32,660
So that didn't change at all.
36
00:02:32,670 --> 00:02:37,100
We added the and character at the end to run the command in the background.
37
00:02:37,200 --> 00:02:39,370
And you can do that with all Linux commands.
38
00:02:39,380 --> 00:02:45,930
Not only with this command then we are told that we also want you to redirect the output of a replay
39
00:02:45,930 --> 00:02:47,150
N-G to nowhere.
40
00:02:47,160 --> 00:02:49,270
I don't want to see it on my screen.
41
00:02:49,620 --> 00:02:55,860
And we finished again with an add character to say I want to do all of this in the background.
42
00:02:56,010 --> 00:03:01,330
Don't show me anything but keep this process running in a different thread in the background.
43
00:03:01,410 --> 00:03:04,290
So when I hit Enter now I won't see any output.
44
00:03:04,320 --> 00:03:09,990
The command will be running in the background and then I'll be able to run another command and disconnect
45
00:03:10,080 --> 00:03:11,390
another computer.
46
00:03:11,730 --> 00:03:15,930
So before I run this command I'm going to go to my Windows machine here.
47
00:03:16,140 --> 00:03:24,510
And as you can see I'm connected again right here to my network to UPC PC and if I search for anything
48
00:03:24,510 --> 00:03:28,620
here you can see that I have internet connection.
49
00:03:28,860 --> 00:03:35,280
So this is going to be my first target and my second target is going to be this OS X machine.
50
00:03:35,280 --> 00:03:37,200
So I'm just going to show you its MAC address.
51
00:03:37,200 --> 00:03:38,280
I'm going to do if Campag
52
00:03:41,300 --> 00:03:44,620
and this is the MAC address of the OS X machine.
53
00:03:44,620 --> 00:03:46,430
So it ends up with eight.
54
00:03:46,570 --> 00:03:49,510
And if we come here we can see it.
55
00:03:49,540 --> 00:03:50,770
It's right here.
56
00:03:51,130 --> 00:03:52,510
So I'm actually going to copy it.
57
00:03:53,530 --> 00:03:58,510
And I'm going to run this command and you'll see when I hit enter or once anything on screen I'll just
58
00:03:58,510 --> 00:04:02,400
see a prompt telling me that this command is running and that's it.
59
00:04:02,410 --> 00:04:05,730
I want see the same output that we got in previous video.
60
00:04:06,040 --> 00:04:12,120
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
61
00:04:12,130 --> 00:04:18,840
so this is the number of jobs that's running in the background of this particular terminal window.
62
00:04:18,850 --> 00:04:26,440
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
63
00:04:26,440 --> 00:04:28,200
command that I used.
64
00:04:28,930 --> 00:04:32,250
So this is the authenticating the Windows machine at the moment.
65
00:04:32,380 --> 00:04:33,630
And we'll go to it in a second.
66
00:04:33,640 --> 00:04:39,310
I just want to do the OS X machine and then we check out the two machines and see how both of them lost
67
00:04:39,310 --> 00:04:40,250
their connection.
68
00:04:40,570 --> 00:04:43,200
So I'm going to run the exact same command again.
69
00:04:43,420 --> 00:04:48,640
Instead of the MAC address of the windows I'm going to put the MAC address of the OS X machine
70
00:04:52,050 --> 00:04:54,000
and I'm going to hit enter.
71
00:04:54,810 --> 00:05:00,920
And you can see that I have another job added to the background and this one has an idea of number two.
72
00:05:00,960 --> 00:05:08,130
So if I do jobs you can see that I have two jobs running there the exact same command target in the
73
00:05:08,130 --> 00:05:09,360
exact same network.
74
00:05:09,420 --> 00:05:15,320
But one of them is targeting the Windows machine and the other is targeting my Mac OS X machine.
75
00:05:15,360 --> 00:05:22,350
So we go to the Windows machine and we look at the bottom and sure enough it doesn't have internet connection
76
00:05:22,350 --> 00:05:23,120
right here.
77
00:05:23,460 --> 00:05:26,340
And even if I try to go to a web website just to confirm that
78
00:05:29,770 --> 00:05:34,130
we can see that it's completely disconnected from its network.
79
00:05:34,150 --> 00:05:39,940
Now I'm going to go to the OS X machine and try to open the browser right here.
80
00:05:41,540 --> 00:05:43,050
Let's try to go to Google.
81
00:05:48,990 --> 00:05:51,680
And as you can see there is nothing shown up.
82
00:05:51,810 --> 00:05:55,080
We can connect to Google or we can't go to any Web site we want.
83
00:05:55,080 --> 00:05:58,460
We literally have no connection to the network.
84
00:05:58,590 --> 00:06:04,500
So we managed to do that by running a display ngi twice on those two specific devices.
85
00:06:04,500 --> 00:06:09,390
So if you wanted to target two devices three devices again run the command three times you want to target
86
00:06:09,390 --> 00:06:11,330
five devices around at five times.
87
00:06:11,370 --> 00:06:16,470
This can be very useful if you wanted to connect a number of devices but not all devices.
88
00:06:16,470 --> 00:06:21,990
So you wanted to target two or three devices and keep your own device or a certain device connected
89
00:06:22,200 --> 00:06:24,000
for a certain reason.
90
00:06:24,000 --> 00:06:26,610
Now these commands are still running in the background.
91
00:06:26,820 --> 00:06:32,340
So if you can stop them based on the idea right here so you can see that the first command has an idea
92
00:06:32,340 --> 00:06:33,300
of number one.
93
00:06:33,420 --> 00:06:40,230
And the second command has an idea of number two so you can stop all of them by saying kill all
94
00:06:43,040 --> 00:06:44,000
a replay ngi
95
00:06:47,840 --> 00:06:52,800
and that will stop all airplay Engy processes including the two of them.
96
00:06:52,910 --> 00:07:01,530
But if you wanted to stop one of them at a time then you're going to do kill percentage number one.
97
00:07:01,720 --> 00:07:04,750
And that will only kill the first process.
98
00:07:04,750 --> 00:07:07,840
So that's only going to kill our windows machine process.
99
00:07:08,140 --> 00:07:14,490
And if we do jobs now you can see that the first process got terminated.
100
00:07:14,740 --> 00:07:20,610
But the second one is still running now I'm going to do the second command the kill all command just
101
00:07:20,610 --> 00:07:21,540
to show it to you.
102
00:07:21,540 --> 00:07:25,250
And this command will kill all airplay and instances.
103
00:07:25,260 --> 00:07:26,370
So if we do kill all
104
00:07:32,220 --> 00:07:38,430
and then do jobs you'll see that the second process also got terminated.
105
00:07:38,430 --> 00:07:40,720
So it could have killed that with percentage too.
106
00:07:40,860 --> 00:07:46,940
Or you can do this method if you wanted to just stop the attack and kill all the instances that this
107
00:07:46,950 --> 00:07:49,420
connected devices do.
