1 00:00:00,240 --> 00:00:01,910 Hello everybody and welcome back. 2 00:00:01,920 --> 00:00:07,300 Now in this lecture we will come on our first program that we will use which is called Mach changer. 3 00:00:07,320 --> 00:00:13,440 It allows us to change our mac address which can be used for multiple things such as for example if 4 00:00:13,440 --> 00:00:16,270 on a particular by wireless network. 5 00:00:16,560 --> 00:00:21,240 There is a blacklist or white list which is based on the MAC addresses. 6 00:00:21,240 --> 00:00:25,270 You can bypass that with simply changing your MAC address. 7 00:00:25,290 --> 00:00:28,530 Now a program that we will use is called Mac change. 8 00:00:29,280 --> 00:00:35,010 If you just type here in the terminal Mac changer you will notice that it will print the usage of the 9 00:00:35,010 --> 00:00:35,520 command. 10 00:00:35,670 --> 00:00:37,140 So here it is. 11 00:00:37,140 --> 00:00:41,580 We need to change your options and then the device. 12 00:00:41,610 --> 00:00:47,280 Now in order to check out our available options we can type here as it says try Mac change their dash 13 00:00:47,310 --> 00:00:47,580 help. 14 00:00:47,610 --> 00:00:54,360 So we will type Mac changer test help and we will basically show us right here some of the available 15 00:00:54,360 --> 00:00:59,340 options that we can use right now in order to find out what our mac addresses. 16 00:00:59,340 --> 00:01:07,150 We want to use this option which is minus minus or dash this show or minus us. 17 00:01:07,350 --> 00:01:16,590 Now if we just type here Mac changer minus it people say that we incorrectly used this program because 18 00:01:16,680 --> 00:01:19,020 we didn't specify the device. 19 00:01:19,020 --> 00:01:26,240 Now this device basically means your network interface card you might be having multiple interface cards 20 00:01:26,260 --> 00:01:29,120 so we want to pick one if you type here. 21 00:01:29,130 --> 00:01:31,590 I have config as we called in the previous Toros. 22 00:01:31,590 --> 00:01:36,260 It will print you up with your network interfaces here. 23 00:01:36,330 --> 00:01:37,680 I only have look like interface. 24 00:01:37,740 --> 00:01:42,510 And the H O interface with the which I use to connect to the Internet. 25 00:01:42,540 --> 00:01:53,820 So I will use this one if I just repeat the command changer minus X and then 88 Joe it will print out 26 00:01:53,820 --> 00:02:00,360 my current MAC address and my permanent back address with it which in this case are both the same because 27 00:02:00,360 --> 00:02:02,130 we didn't change it yet. 28 00:02:02,190 --> 00:02:08,130 Now if you have multiple interfaces just pick the one you use currently and just specify it at the end 29 00:02:08,160 --> 00:02:13,580 the command now Let's type here it once again the iMac changer. 30 00:02:13,630 --> 00:02:18,820 Does that help in order to see what else we can do with this program. 31 00:02:18,970 --> 00:02:23,130 So we cover this part which is show showing our current MAC address. 32 00:02:23,140 --> 00:02:26,080 Now let's say we want to change the MAC address. 33 00:02:26,080 --> 00:02:29,160 We can look some of the options here. 34 00:02:29,170 --> 00:02:36,010 It says set fully random MAC address which we can do with the minus r or dash dash random. 35 00:02:36,880 --> 00:02:43,670 So let's try to put the random MAC address and see what happens if we type here. 36 00:02:43,750 --> 00:02:50,200 Mac changer minus r which stands for this option right here which is set for the random MAC address 37 00:02:50,860 --> 00:02:58,480 and then we specify once again our network interface we can see that right now our MAC address is changed 38 00:02:59,250 --> 00:03:00,290 as you can see right here. 39 00:03:00,310 --> 00:03:04,810 New Mac is this one the previous one was this one. 40 00:03:05,290 --> 00:03:10,220 So if we want to show our mac address again we we can see that it has changed. 41 00:03:10,610 --> 00:03:13,230 Oops I forgot to specify the interface. 42 00:03:13,450 --> 00:03:19,760 We can see that the current MAC address is a different one from the permanent one and we can see it 43 00:03:19,820 --> 00:03:26,110 we successfully changed the MAC address but let's say for example you want to bypass the white list 44 00:03:26,110 --> 00:03:34,060 of the MAC addresses you would want to specify a specific MAC address so we can do that with this command 45 00:03:34,210 --> 00:03:41,350 which is basically dash dash Mac and then specifying a MAC address let's say for example we want the 46 00:03:41,950 --> 00:03:42,550 MAC address. 47 00:03:42,580 --> 00:03:46,630 Let me just open another terminal right here. 48 00:03:46,630 --> 00:03:49,590 Let's say we need to have this MAC address right here 49 00:03:54,980 --> 00:03:58,870 we can try to get it with the minus command. 50 00:03:59,240 --> 00:04:00,620 We just move this right here. 51 00:04:00,620 --> 00:04:08,370 So if we run once again Mach changer minus we will go dash dash Mac. 52 00:04:08,370 --> 00:04:09,620 Now we will set here. 53 00:04:09,630 --> 00:04:12,810 The MAC address here. 54 00:04:12,930 --> 00:04:16,830 We will put equal I'm not sure if we need to put equal rights here. 55 00:04:16,830 --> 00:04:27,660 We will try that first and then 2 2 3 3 4 4 5 5 6 6 7 7 and then we will specify our network interface. 56 00:04:27,660 --> 00:04:33,360 So if we see right here it's changed our Mac to the specific MAC address that we wanted it changed too. 57 00:04:34,080 --> 00:04:41,530 So right now once again if we type Mac change or minus minus show. 58 00:04:42,060 --> 00:04:44,220 Now it is like this. 59 00:04:45,300 --> 00:04:49,110 Yes I always forget to specify the network interface. 60 00:04:49,110 --> 00:04:57,450 We can see that our current MAC address is 2 2 3 3 4 4 5 5 6 6 7 7 and our permanent Mac is our normal 61 00:04:57,450 --> 00:05:04,400 MAC address which doesn't really change oh yes if we want to we can reset back to the original permanent 62 00:05:04,400 --> 00:05:07,720 hardware MAC with the minus B comment. 63 00:05:07,730 --> 00:05:13,820 Now if you're finished with your attack for example and you want to change this IP address back to the 64 00:05:14,290 --> 00:05:20,960 let me just type here again to the normal and not IP address MAC address to the normal MAC address which 65 00:05:20,960 --> 00:05:25,480 is our permanent MAC address you can do that with minus B command. 66 00:05:25,520 --> 00:05:33,290 So let's try that Mac change your minus peak and then our network interface and we can see that the 67 00:05:33,290 --> 00:05:36,050 new Mac is now the same as the permanent Mac. 68 00:05:36,110 --> 00:05:41,140 And now we are back to normal. 69 00:05:41,180 --> 00:05:48,020 We can just type your show again and we are the same as we started before using this program and this 70 00:05:48,020 --> 00:05:51,260 is a useful program in for you to change MAC address. 71 00:05:51,260 --> 00:05:55,940 You can even put it to change it at the boot up of this machine. 72 00:05:55,940 --> 00:06:01,730 So it changes basically every time you restart the machine it will change your mac address which can 73 00:06:01,730 --> 00:06:04,880 be used to provide a little bit of anonymity. 74 00:06:04,910 --> 00:06:07,970 But I to use that you can if you want to. 75 00:06:08,340 --> 00:06:10,900 And that's about it for this program. 76 00:06:10,910 --> 00:06:12,350 It is one of the simple ones. 77 00:06:12,350 --> 00:06:19,510 So we covered it first in the next lecture we will cover a Google hacking which is also pretty simple. 78 00:06:19,580 --> 00:06:24,080 So I'll show that in the next lecture and I hope I see you there and they can.
