WEBVTT 00:00.560 --> 00:04.030 Hello everyone and welcome to part nine of my learned ethical hacking in this video. 00:04.030 --> 00:08.930 We're going to look at how to disconnect any device that is connected to Wi-Fi router. 00:09.260 --> 00:13.220 In this video we're going to be using my my MacBook laptop as an example. 00:13.250 --> 00:17.640 So I have a router in my room and my macbook is connected to it. 00:19.010 --> 00:23.500 So what I'm going to do is I'm going to prevent the connection from the laptop and the router. 00:23.600 --> 00:28.700 It's not going to be able to connect back to the Wi-Fi router and it's not going to have Internet access 00:28.700 --> 00:30.490 at all. 00:30.490 --> 00:32.750 Now I must say this is for educational purposes only. 00:32.750 --> 00:35.810 I'm not responsible for any damages you cause or consequences. 00:35.810 --> 00:42.200 The whole purpose of this is for education and for people who are generally interested in whites hacking 00:42.260 --> 00:44.870 and also cyber security. 00:45.110 --> 00:47.100 So to get started. 00:47.330 --> 00:55.640 I'm going to check the Wi-Fi card so if I do I w conflict w lan Zero Month click enter. 00:55.670 --> 00:58.750 As you can see the mode is monitor so I can just clear that. 00:58.770 --> 01:06.420 Now I'm going to do a real dump and G then w Le Monde zero click enter. 01:06.460 --> 01:14.450 And this is going to start from packets around the local or local races that are in my area. 01:14.450 --> 01:16.440 I'm using a wireless card. 01:16.490 --> 01:21.350 So if you haven't watched the previous videos and you just happen to find this video then you will need 01:21.350 --> 01:22.670 to go and watch them. 01:22.670 --> 01:26.960 There's a whole playlist on my channel of them and it will give you a better understanding of what is 01:26.960 --> 01:28.070 actually happening here. 01:29.390 --> 01:31.970 So I'm going to press control C to stop it. 01:32.300 --> 01:38.780 I've already explained in part seven what all this means but what we're going to do is we're going to 01:38.900 --> 01:41.730 actually just attack a specific device now. 01:41.930 --> 01:50.220 So my laptop is connected to this network the reason I know this is because obviously it's got the same 01:50.250 --> 01:53.670 ISIS I.D. on the laptop when searching for it. 01:53.850 --> 01:58.710 So we'll just be the same name as the Wi-Fi router. 01:59.430 --> 02:02.400 And this is the MAC address for that router. 02:02.400 --> 02:04.770 So we've sniffed the router. 02:04.770 --> 02:07.530 Now what we need to do is we need to actually target the sniffing. 02:07.530 --> 02:12.420 So basically we're going to actually just sniff every device that is connected to this Wi-Fi router 02:13.560 --> 02:20.950 so to do so I'm going to do a rodent haven energy then the channel channel. 02:21.240 --> 02:25.940 This channel is what the network or the Wi-Fi Rusi uses. 02:26.070 --> 02:30.840 So it uses Channel 6 as you can see here it says CBH 6. 02:31.140 --> 02:33.540 Then we're gonna do hyphen hype and be a society. 02:34.140 --> 02:40.510 So we need to copy this society and paste it here which is the MAC address of the router. 02:40.830 --> 02:45.910 Then you just need to type w lan 0 1. 02:45.940 --> 02:52.680 Now I have explained or have said before in previous videos that this could change for you as long as 02:52.680 --> 02:55.770 your Wi-Fi call it is in monitor mode then you're good to go. 02:56.100 --> 03:04.890 So if I click and to no it's going to start sniffing devices that connected to this Wi-Fi so if I press 03:04.890 --> 03:11.230 control and to stop this device here this MAC address corresponds to my macbook. 03:11.280 --> 03:17.400 The reason I know this is because I know the MacBook and the MacBook mac address if that makes sense 03:17.510 --> 03:19.430 a bit awkward to say. 03:19.560 --> 03:24.920 So what I'm going to do now is I'm going to switch over to my Mac Book and show you that I'm not lying 03:24.920 --> 03:30.750 or making this all so I'll see you on my macbook. 03:30.870 --> 03:37.020 So now that I'm on the Mac book as you can see the Wi-Fi is connected I'm connected to that same specific 03:37.020 --> 03:40.900 Wi-Fi router which is this 2G one. 03:41.310 --> 03:43.400 I will show you that the Internet actually goes way up. 03:43.410 --> 03:51.780 So I'll go on the browser and just go to YouTube click enter as you can see YouTube does load not sounding 03:51.810 --> 03:56.940 because obviously it's all it's new a new device it's not really used but it's just a proof that the 03:56.940 --> 04:02.250 Internet does actually work on this laptop go back here go to advanced. 04:02.250 --> 04:03.210 Then go to hardware. 04:03.270 --> 04:12.420 As you can see the MAC address of this laptop is b 8 8 D 12 forty one zero C so if we go back a few 04:12.420 --> 04:16.320 seconds into the video and you will notice that this MAC address corresponds to the MAC address that 04:16.320 --> 04:24.150 we sniffed when we join the target we targets is the specific Wi-Fi to find devices that are connected 04:24.150 --> 04:24.420 to it. 04:25.080 --> 04:30.450 So VBA data corresponds to the macro address that we have found that way. 04:30.460 --> 04:38.030 Well that's how I know that this is the correct MAC address on this laptop that we are targets and. 04:38.060 --> 04:44.750 So what we're gonna do now is we're going to actually send D authentication packets to this laptop that 04:44.750 --> 04:49.530 will disconnect and prevent further connection to this Wi-Fi spot. 04:49.640 --> 04:56.530 It will way for this device to this device will be basically unable to connect to the Wi-Fi router. 04:56.900 --> 05:03.470 So I'll see you back on the Linux machine and then I'll teach you how to send these d authentication 05:03.470 --> 05:08.910 packets so another way back on the current Linux machine as you can see here. 05:09.100 --> 05:10.730 It's this MAC address. 05:10.870 --> 05:15.730 So like I said it corresponds to the MAC address that is the MAC address of the MacBook. 05:17.110 --> 05:25.810 And that is exactly what we want because we want to target this specific device now to send the authentication 05:25.810 --> 05:29.550 packets or we need to do is this simple code or the simple line. 05:30.040 --> 05:36.380 So air play hyphen energy make sure the. 05:36.640 --> 05:44.950 So I R E an n play a play energy I just call it airplay engines to save up or doesn't matter. 05:44.960 --> 05:51.070 They don't want to hype and hype from deal so d of the D authentication a thousand. 05:51.370 --> 05:56.560 Actually I'll do 10000 so basically this number of packets the number of D authentication Pakistan we're 05:56.560 --> 05:59.320 gonna send that I'm gonna do hyphen A. 05:59.470 --> 06:03.570 Then we need to put the BSE idea of the network or the router. 06:03.670 --> 06:09.580 So like I've said before this MAC address is the MAC address of the router. 06:09.610 --> 06:13.850 Now these are all the same because these are the devices connected to this router. 06:13.990 --> 06:18.400 So it just needs a copy this MAC address which is the MAC address of the router you got to remember 06:18.400 --> 06:20.590 that it's very important that you put them in the right way. 06:21.790 --> 06:28.790 So I'm going to paste it then I'm going to do a space in an n hyphen C then I'm going to put the BSD 06:28.800 --> 06:37.750 idea of the client which is the device that we want to prevent connexion from or to this network which 06:37.750 --> 06:39.090 is this one. 06:39.220 --> 06:48.630 So basically put in the MAC address of the Mac book here then I'm going to type w lan 1 0 w 1 0 1 Sorry 06:49.300 --> 06:54.370 and as soon as I click enter it's going to start flooding the connection between the MacBook and the 06:54.370 --> 06:58.560 router with deal with packets. 06:58.720 --> 07:04.600 So I'm just going to click enter now and quickly show you what's going to happen to my Mac Book. 07:04.990 --> 07:09.210 Well because of the Mac books next to me I don't want it to lock so I have to type the password in and 07:09.210 --> 07:09.820 animist it. 07:10.330 --> 07:14.530 So as soon as I click enter the MacBook screen will appear and I'll show you the effects of what we're 07:14.530 --> 07:17.230 doing so click enter. 07:17.680 --> 07:21.070 It's going to start sending deal packets and I will see you on the MacBook 07:26.620 --> 07:32.620 as you can see on the MacBook now if you noticed up here it's actually struggling to connect to the 07:32.680 --> 07:33.820 Wi-Fi now. 07:34.210 --> 07:42.610 It's gonna keep trying but if I show you the screen on my carry Linux machine then I can see it's just 07:42.610 --> 07:43.340 floating. 07:43.390 --> 07:49.970 The connection with Deal's pockets so obviously this laptop can not connect to the Internet. 07:50.320 --> 07:57.010 It's just gone gray it's gone black there's no even one little bar of connection there's just no connection 07:57.070 --> 07:59.970 at all and I can close out to this and show you. 08:00.250 --> 08:07.380 So as you can see the Wi-Fi is on but no network selected so if I try and select to 2G click on 2G as 08:07.490 --> 08:15.840 you can see this is connected I'll give it a second just to send a few more days of packets and the 08:15.840 --> 08:17.420 connections gone again. 08:17.580 --> 08:22.080 So the connection to stay open a little bit but obviously once it recognizes that deals packets would 08:22.080 --> 08:22.860 be incentive. 08:22.860 --> 08:24.230 It just disconnects. 08:24.360 --> 08:29.160 I'll try and connect back to youtube again so if I click enter I can see there's a problem load in the 08:29.160 --> 08:30.210 page. 08:30.240 --> 08:34.920 So basically this device is rendered useless for connecting to this Wi-Fi router. 08:34.920 --> 08:42.310 Obviously you can connect to different ones but obviously then if we change the attack on the coffee 08:42.310 --> 08:47.730 machines to the or the MAC address of the other router then it will still render useless. 08:49.050 --> 08:54.210 So this can be quite complicated tor quite quick when I'm talking about this stuff because that's how 08:54.210 --> 08:57.560 I am sorry if it doesn't really make sense. 08:57.630 --> 09:02.250 Just go through the video slowly and watch the other parts of this course and it will make sense to 09:02.250 --> 09:08.370 you as you can see there is no Internet connection now I can't connect to the Internet and that is the 09:08.370 --> 09:15.670 whole point of the deal authentication as long as I stop it on the coffee machine then the connection 09:15.670 --> 09:16.320 will come back. 09:16.330 --> 09:23.700 So it's not completely ruined or permanently damaged but obviously the connection will only come back 09:23.730 --> 09:27.800 or on setting off the Linux machine. 09:27.950 --> 09:32.030 So I'm just going to go back to the tally machine now and I will see you on there. 09:32.930 --> 09:37.580 So now that we're back on the cutting machine to stop sending the d off packets so you need to do press 09:37.580 --> 09:41.520 control and see so control C and that will stop the attack. 09:41.540 --> 09:47.560 You can also just close out of the terminal or turn off the column machine. 09:48.200 --> 09:49.850 So that was a for the video. 09:49.850 --> 09:51.080 If it did help please leave. 09:51.070 --> 09:55.520 Like if you're stuck with anything or have any errors please leave it in the comments and I'll be happy 09:55.520 --> 09:56.230 to help. 09:56.270 --> 09:59.360 Describe for the latest contents and I will see you in the next video.
