1 00:00:00,980 --> 00:00:09,200 Address each network card whether it's Wi-Fi card or wild card it has a physical static address assigned 2 00:00:09,200 --> 00:00:16,220 by the card manufacturer called the MAC address Media Access Control this MAC address is actually written 3 00:00:16,520 --> 00:00:18,520 on your card and it's physical. 4 00:00:18,520 --> 00:00:24,610 So it doesn't it never changes for your card for your specific card for example for your wife or a card. 5 00:00:24,620 --> 00:00:25,600 It will never change. 6 00:00:25,610 --> 00:00:28,140 It will always be the same. 7 00:00:28,310 --> 00:00:34,760 The MAC address is used between devices to identify each other and to transfer packets and the right 8 00:00:34,760 --> 00:00:35,990 direction. 9 00:00:35,990 --> 00:00:42,860 This works by each packet has a source mark and a destination mag and it travels from the source smog 10 00:00:43,160 --> 00:00:44,760 to the destination. 11 00:00:45,200 --> 00:00:53,090 Now because the MAC address is static and it never changes it can be used to trace you back and to identify 12 00:00:53,090 --> 00:00:54,640 your device. 13 00:00:54,650 --> 00:00:58,580 Also since devices used MAC address to identify each other. 14 00:00:58,610 --> 00:01:00,680 So for example you have some networks. 15 00:01:00,680 --> 00:01:04,340 They are only allow certain marketplaces to connect to the network. 16 00:01:04,340 --> 00:01:11,330 They use a whitelist or think they can use a blacklist and blacklist your MAC address so that you cannot 17 00:01:11,330 --> 00:01:13,460 connect to that network. 18 00:01:13,460 --> 00:01:18,560 So changing your MAC address can help either connect to the network by changing your MAC address to 19 00:01:18,560 --> 00:01:24,640 one that's in a whitelist or it could let you bypass blacklists. 20 00:01:24,710 --> 00:01:27,260 So as I said it's physical and static. 21 00:01:27,320 --> 00:01:31,370 So the only way to change the MAC address is the changes in the. 22 00:01:31,490 --> 00:01:34,100 So it's going to be changed for this session. 23 00:01:34,100 --> 00:01:36,940 Once you research your device you have to change it again. 24 00:01:37,280 --> 00:01:41,390 So to do this it's very simple we're going to use a tool called Match changer. 25 00:01:41,720 --> 00:01:48,810 So let's see how we do that so first of all to get your wife I can name just type in either Blue config 26 00:01:49,410 --> 00:01:51,510 and it will show all wireless cards you have. 27 00:01:51,510 --> 00:01:55,210 So here it Yoshiro has no wireless extensions. 28 00:01:55,270 --> 00:01:56,910 And same with L-O. 29 00:01:56,910 --> 00:01:59,660 And we can see that last year is my wireless card. 30 00:01:59,910 --> 00:02:07,110 So I'm just going to disable the wireless card so if config Landseer of down does to disable the wireless 31 00:02:07,110 --> 00:02:08,570 card. 32 00:02:08,810 --> 00:02:11,610 Now we're going to change the MAC address. 33 00:02:11,610 --> 00:02:14,720 We're going to use a tool called Mac changer. 34 00:02:14,720 --> 00:02:18,560 So always with these tools it's always a good idea to look at the help. 35 00:02:18,590 --> 00:02:26,720 So if you just go on my changer help you will see all the options that we can use with this too. 36 00:02:27,050 --> 00:02:32,270 So you can use help and version to show the version and help show to show your current Mac address. 37 00:02:34,040 --> 00:02:39,280 So that it doesn't change the vendor bytes it doesn't change the manufacturer of the MAC address. 38 00:02:39,290 --> 00:02:41,700 So in other words just try a random vendor. 39 00:02:41,750 --> 00:02:47,280 Much of the same kind is just to set a random vendor here. 40 00:02:47,330 --> 00:02:54,050 The capital P will reset to the original permanent MAC address so if you change your MAC address and 41 00:02:54,050 --> 00:03:00,350 you want to use the old one you can use p or we'll just give you a random MAC address and we'll just 42 00:03:00,350 --> 00:03:02,710 print the number and the result you can use. 43 00:03:02,790 --> 00:03:10,100 And actually it'll help you pick your MAC address so you can if there is a white list and I'll show 44 00:03:10,100 --> 00:03:12,230 you how you can see all connected devices. 45 00:03:12,230 --> 00:03:17,960 So if your target network you can see is for example three devices connected and this network only allows 46 00:03:17,960 --> 00:03:19,500 these three devices connect. 47 00:03:19,610 --> 00:03:25,270 So you can just take one of those MAC addresses and change it and use it yourself and then try to connect 48 00:03:25,310 --> 00:03:27,420 and it'll allow you to connect. 49 00:03:27,440 --> 00:03:28,980 So that's how we change the MAC address. 50 00:03:28,990 --> 00:03:37,130 We're going to use my changer again and I'm just going to use random to set up a random MAC address 51 00:03:37,790 --> 00:03:40,520 and then we'll put the device name which is land zero. 52 00:03:40,790 --> 00:03:47,030 So for example my kid my changer random Landseer up you can use the app to specify your MAC address 53 00:03:47,030 --> 00:03:48,280 if you want. 54 00:03:48,290 --> 00:03:56,470 So I'm going to hit enter and as you can see my original one was this and it's been changed to 9 8 8 55 00:03:56,470 --> 00:03:59,080 4 0 9 5 s.a.a 3. 56 00:03:59,470 --> 00:03:59,950 OK. 57 00:04:00,010 --> 00:04:03,670 So now our wireless cards is ready and we've changed its MAC address. 58 00:04:03,670 --> 00:04:10,270 Now we need to enable it again because we disable that by typing config last zero down. 59 00:04:10,270 --> 00:04:11,680 So we'll do the opposite. 60 00:04:11,680 --> 00:04:16,950 Will we do something like 0 up and that's it. 61 00:04:16,950 --> 00:04:20,270 The card is enabled and its MAC address has been changed. 62 00:04:20,270 --> 00:04:21,700 Let's just have a look on it. 63 00:04:21,810 --> 00:04:24,420 If you type in ifconfig line 0. 64 00:04:24,810 --> 00:04:27,970 Now we can see the new MAC address shown up in here.
