00:00Disclaimer. This is educational purpose video only. I didn't harm anyone I used my own device

00:14during explain of this method so please don't use this method any kind of illegal or malicious

00:18activities. Because hacking is crime. If you do this then it's can land you in jail. I'm not

00:24support any kind of illegal or malicious hacking.

00:36We're chosen as usual. So let me go here and give my password and then go to my terminal.

00:48So I'm going to need to run aero dump ng one more time in here because

00:53I need to get the device mac addresses right? So let me run aero dump ng and this time we don't have to

01:02write this to a file right? Because we don't need to analyze it later on. I'm just going to take the

01:10results in real time and have my deauthentication attack on this router. So of course if you want you

01:19can write again but I'm not going to do that because it may slow my process down. So let me delete this

01:28line here and hit enter in order to start this command. So this is the same command that we have

01:35run in the previous lecture. So now we are getting the station and the SSID columns in here. So we know

01:45the mac addresses of connected devices. So if I say file open terminal from here then I will get another

01:53terminal. So let me just make this one smaller and put it down. So I'm going to just take the values from

02:04above so it's easier to see it that way. Because I'm going to run airplay ng. I will have to specify

02:15the station mac address along with the bssid of router as well. So let me start by typing airplay ng.

02:25So this is the name of that tool. An aerodump, airplay and a tool called aircrack ng are all connected as

02:35you can understand right now. And we're going to see what is aircrack in the following lectures.

02:43So I'm going to go after my macbook in here and of course you cannot know which mac address belongs to

02:52which device is at your house. I suggest you try to find a way to know the mac address or you can just

03:00go after one and see which one is disconnected. So I'm going to say airplay ng and d of as we have seen

03:08in the documentation. And then I'm going to specify the number of packets that I want to send. So if you

03:16write something like 1000 or 10 000 in here you're going to send a lot of packets and you're going to

03:24disconnect the user and they will certainly know that they are disconnected. So sometimes you want to

03:32send some smaller packets like 5 or 10 in order to disconnect a user from the network and in order not

03:42let them know that they are disconnected. So there are reasons to do that and we're going to see them in

03:48the following lectures. So later on I'm going to say dash a to specify the mac address okay. So I'm going to

03:59copy this one and paste it in here. And then I'm going to say dash c in order to copy and paste

04:10the client's mac address. And I believe by mistake I'm copying this twice okay. So let me paste it in here.

04:19And client c stands for client so you have to copy the devices mac address and a stands for access point.

04:27So you have to copy here the router mac address and it's written in the bssid column. So I'm going to copy

04:36this and paste this and paste in here. So you have to be careful with this one a is for access point c is for clients okay. So after doing that

04:50that of course we have to specify our interface name. And once I hit enter as you can see it started to send

05:00the authentication packets. So right now um as you can see I'm getting this frames in here. So this station

05:12belongs to my macbook and I'm getting in here. And actually at this point even though we can see

05:22the station in the list my macbook got disconnected from the network. And even though it seems like it's

05:31disconnected it cannot go to the internet. So we will see that we're getting on and off from this

05:38authenticated list in the aerodump ng. Even though we are on the list it won't work for me. Because I'm

05:46getting constant packets from the of constant packets from airplay in here. Of course at this point I

05:55cannot prove to you that I'm disconnected and I cannot connect to the internet. But um let me stop

06:02here actually. And within the next lecture I'm going to deauthenticate my macbook my host machine in order

06:10to show you that this is actually working. And of course you have to try this on your own with your own

06:17devices. So that you can confirm this and see that this is working in real life examples as well.

06:27And as I said before there is no way to understand which mac address belongs to which device at this point.

06:34But you can go for them anyway. You can choose one of them and try to disconnect them anyway and try it on your own house.

06:42So let's stop here and do that in the following lecture.
