WEBVTT 00:00.880 --> 00:04.320 Hi friends, welcome to changing Mac address section. 00:04.320 --> 00:11.440 In this section we are going to learn how we can change Mac address for a device or a computer. 00:11.480 --> 00:12.120 Okay. 00:12.160 --> 00:16.360 And then we will learn how to create our program okay. 00:16.400 --> 00:21.960 Python program that these program changes Mac address. 00:21.960 --> 00:32.840 So before we start we need to know what is a mac address okay a mac address is a it is a physical address 00:32.840 --> 00:34.000 okay. 00:34.080 --> 00:37.560 Mac address stands for Media Access Control. 00:38.040 --> 00:46.400 And it is a physical, permanent and completely unique for each devices that is assigned by its manufacturer. 00:46.400 --> 00:46.800 Okay. 00:47.000 --> 00:51.920 For example, this computer that I have right now and I'm using it, it has a mac address. 00:51.920 --> 00:55.480 It has something that is completely unique in this world. 00:55.920 --> 00:58.200 No other devices has that kind of Mac address. 00:58.240 --> 00:59.240 Okay. 00:59.240 --> 01:00.000 And. 01:02.400 --> 01:04.640 Uh, what is it used for? 01:04.760 --> 01:05.280 okay. 01:05.320 --> 01:09.320 It is used for transferring the packets from one device to another. 01:09.320 --> 01:12.120 Devices from one computer to another computer. 01:12.160 --> 01:12.600 Okay. 01:13.400 --> 01:16.280 While packets, you may ask, what is packet? 01:16.320 --> 01:16.640 Okay. 01:16.680 --> 01:22.760 The packet is the data that we are sending from one computer to another computer. 01:23.360 --> 01:29.200 So this packet that we send, it has a source Mac address and a destination Mac address. 01:29.440 --> 01:29.840 Okay. 01:30.200 --> 01:33.600 These both are unique for each devices. 01:33.600 --> 01:37.160 And this both are completely unique. 01:37.160 --> 01:44.360 And it is transferring the data or those packets that is sent to network. 01:46.000 --> 01:48.680 And why should we change it okay. 01:48.720 --> 01:52.200 Because in this section we are going to learn change it to change it. 01:52.200 --> 01:54.800 And why should we change it. 01:54.920 --> 02:02.240 Is it really necessary to change it in hacking world or in hacking area? 02:02.560 --> 02:07.880 Yes, of course it is necessary because it increase being anonymity. 02:07.920 --> 02:08.280 Okay. 02:08.320 --> 02:16.320 Being anonymous, and it is used in a lot of a lot of places. 02:16.360 --> 02:16.800 Okay. 02:17.360 --> 02:20.920 That we will be discussing them later on. 02:20.920 --> 02:23.240 And here I'm going to just name them. 02:23.280 --> 02:23.960 Okay. 02:24.000 --> 02:26.040 For example there are some kind of filter. 02:26.080 --> 02:26.360 Okay. 02:26.400 --> 02:34.400 Mac address filtering that it is they are telling for example on a Wi-Fi network, the administrator 02:34.440 --> 02:42.680 telling that only the devices could connect to this network that has a specific Mac address. 02:42.720 --> 02:46.200 So if you change your Mac address to their Mac address okay. 02:46.960 --> 02:50.960 So you will be able to change to connect to that network too. 02:51.000 --> 02:56.440 So we can bypass the Mac address filtering by changing the Mac address. 02:58.800 --> 03:02.120 And it could hide your identity. 03:02.320 --> 03:02.720 Okay. 03:03.480 --> 03:13.360 So also let's go and see how we can change it from tools that is already into Kali Linux. 03:13.400 --> 03:13.800 Okay. 03:14.640 --> 03:19.440 And then we will be learning how to create our own tools to change it. 03:19.640 --> 03:27.360 So let me show you the Mac address first in Kali Linux, if you write ifconfig and hit enter here you 03:27.360 --> 03:28.600 have two things okay. 03:28.640 --> 03:30.200 One of them is eth0. 03:30.200 --> 03:32.160 And then we have low. 03:32.200 --> 03:34.000 Now, right now forget about this okay. 03:34.040 --> 03:36.800 It is a network that is created by Kali Linux. 03:36.800 --> 03:42.960 And this one it is a wired network that is created is virtual network okay. 03:42.960 --> 03:46.760 Right now that is created by virtual machine or VirtualBox. 03:47.640 --> 03:54.280 And right here you see that we have an IP okay. 03:54.320 --> 03:55.440 That is here. 03:55.480 --> 03:58.480 Each network needs to have an IP okay. 03:58.880 --> 04:05.280 This belongs to an interface which which its name is eth0 okay. 04:05.320 --> 04:11.360 And it has a mac address which is either okay and this is its Mac address okay. 04:11.400 --> 04:19.310 This Mac address needs to be 12 character all the time And right now you see, this is the Mac address 04:19.310 --> 04:25.550 for this Linux computer that VirtualBox provided for this computer. 04:25.590 --> 04:25.990 Okay. 04:26.990 --> 04:33.110 And if you're trying to find it on windows you need to write IP config. 04:33.150 --> 04:33.750 Okay. 04:33.790 --> 04:34.830 On windows. 04:35.070 --> 04:39.190 And now if I hit enter it is not going to understand it because it's a command for windows. 04:39.190 --> 04:41.030 And I'm using Linux. 04:41.310 --> 04:42.630 So how can we change it. 04:42.670 --> 04:47.670 First we need to turn off this interface which is zero. 04:47.710 --> 04:51.710 No problem if you're using eth0 or LAN. 04:51.750 --> 04:52.190 Okay. 04:53.190 --> 05:00.750 So let's use ifconfig eth0 which is the name of the interface. 05:00.910 --> 05:07.270 If you want to use other interface then you can use the name of that interface okay. 05:07.310 --> 05:09.590 So let's use down and hit enter. 05:10.030 --> 05:13.470 And it is saying that operation not permitted. 05:13.510 --> 05:13.790 Okay. 05:13.830 --> 05:14.030 Why. 05:14.070 --> 05:16.190 Because I'm not a super user. 05:16.230 --> 05:20.070 Let's use sudo ifconfig. 05:20.070 --> 05:20.150 fake. 05:22.510 --> 05:24.190 It a zero down. 05:24.190 --> 05:25.070 Hit enter. 05:25.110 --> 05:28.030 Provide the password. 05:28.150 --> 05:29.510 Now we have no error. 05:29.510 --> 05:33.470 That means now the eth0 is down. 05:33.470 --> 05:36.270 And you see that notification right here. 05:37.630 --> 05:42.230 And now if you want to change it, you need to use ifconfig. 05:42.550 --> 05:45.790 Okay then name of the interface. 05:45.790 --> 05:56.390 And then write h w then ether that is here okay either and then provide a new Mac address. 05:56.430 --> 05:56.670 Okay. 05:56.710 --> 06:02.350 So let's go with zero zero okay 001. 06:05.510 --> 06:10.230 One one and 223344. 06:10.350 --> 06:12.110 And finally five five. 06:12.150 --> 06:14.430 Make sure that it is 12 character. 06:14.470 --> 06:14.870 Okay. 06:15.150 --> 06:16.790 Now I'm going to hit enter. 06:17.150 --> 06:21.230 And again it's going to be sudo. 06:21.270 --> 06:22.590 And now hit enter. 06:22.870 --> 06:25.150 Now I think it is going to going to be changed. 06:25.190 --> 06:31.550 And there is one more thing you need to do, and that is to turn on the this interface again. 06:31.870 --> 06:35.150 So again we're going to use sudo ifconfig. 06:38.430 --> 06:38.870 Okay. 06:39.310 --> 06:42.430 And it is zero app. 06:43.310 --> 06:43.710 Okay. 06:43.750 --> 06:44.670 Now it is done. 06:44.670 --> 06:47.030 And you see that the network is up now. 06:47.390 --> 06:54.630 Now if I use ifconfig and hit enter this time you see that we have this Mac address. 06:55.070 --> 06:55.310 Why. 06:55.470 --> 06:57.430 Because I changed it. 06:57.470 --> 06:58.350 Okay. 06:58.390 --> 07:03.070 And right here, up here, if I show you you see that we had something else. 07:03.070 --> 07:05.510 And now we have this one. 07:05.510 --> 07:06.230 Okay. 07:06.270 --> 07:11.710 So it is how you can change it using a tool that is already provided in Kali Linux. 07:12.310 --> 07:21.310 And in this section we are going to create our own program to change the Mac address for device using 07:21.310 --> 07:24.030 Python programming language. 07:24.230 --> 07:25.830 So let's go and see that. 07:25.870 --> 07:26.670 Okay. 07:26.710 --> 07:27.910 See you in the next video.
