1 00:00:00,790 --> 00:00:01,360 Welcome back. 2 00:00:01,750 --> 00:00:04,620 So for now on half of the program is done good. 3 00:00:04,630 --> 00:00:08,320 We managed to get MAC addresses from our target and our router. 4 00:00:08,320 --> 00:00:14,090 Now it's time to actually perform the hacking stuff and spoof these two targets all right. 5 00:00:14,090 --> 00:00:17,090 So let's do it now that we've got the MAC addresses. 6 00:00:17,090 --> 00:00:18,610 Let's see what's next step. 7 00:00:18,620 --> 00:00:24,980 First of all I'm going to delete these two print statements as we don't really need them at the moment 8 00:00:25,820 --> 00:00:28,470 allow this. 9 00:00:29,010 --> 00:00:36,590 And now if you remember we need to enter a while loop in order for our spoofing to last longer. 10 00:00:36,600 --> 00:00:43,260 So what we are going to do is I'm going to type to try and accept statements right here and industry's 11 00:00:43,260 --> 00:00:46,400 statement or simply just try to support the targets. 12 00:00:46,410 --> 00:00:56,230 So while true we want to spoof and you'll see in just a second what parameters will this pull function 13 00:00:56,260 --> 00:00:57,630 take. 14 00:00:57,850 --> 00:01:03,580 And in the accept statement we want to accept keyboard interruption. 15 00:01:03,580 --> 00:01:08,680 And the reason why we're specifying the keyboard interrupt is because if you take a closer look this 16 00:01:08,680 --> 00:01:14,560 is a while True loop and while True loop are infinite loops that means this false proof for the infinite 17 00:01:14,560 --> 00:01:15,550 amount of time. 18 00:01:15,670 --> 00:01:20,860 Therefore we want to make sure that at any time that we want to stop the program we'll simply just keyboard 19 00:01:20,860 --> 00:01:24,370 interrupt and it foreclose the spoofing. 20 00:01:24,370 --> 00:01:26,980 So it will print right here. 21 00:01:28,120 --> 00:01:34,900 Closing AARP's buffer and then we can simply exit the program. 22 00:01:34,900 --> 00:01:35,890 All right. 23 00:01:36,010 --> 00:01:39,040 So now let's get back to this poll function. 24 00:01:39,040 --> 00:01:41,920 It is read underlined of course because it doesn't exist. 25 00:01:41,920 --> 00:01:43,410 Therefore we will have to code it. 26 00:01:43,810 --> 00:01:48,800 But before we do that let's take a look at what parameters dysfunction should take. 27 00:01:49,150 --> 00:01:56,130 While it actually has to take all of these four parameters right here since we want to spoof both of 28 00:01:56,130 --> 00:02:01,680 the targets and for each of the target we need its own MAC address and its own IP address. 29 00:02:01,680 --> 00:02:07,710 Therefore we need to send all of these four variables into this support function. 30 00:02:07,710 --> 00:02:10,920 Let's keep track of in which order we are sending them. 31 00:02:10,920 --> 00:02:20,570 So we are first of all going to send Raul to IP then we will send targeted IP. 32 00:02:21,370 --> 00:02:27,680 Then we will send Raul or Mac and the last thing we need to send is the target Mac. 33 00:02:27,820 --> 00:02:30,700 So we are sending these four variables. 34 00:02:30,910 --> 00:02:35,220 And right here we will code the function itself. 35 00:02:35,710 --> 00:02:40,690 And keep in mind that we need to specify the exact same order of these variables. 36 00:02:40,900 --> 00:02:43,760 So we don't get error when running the program. 37 00:02:44,080 --> 00:02:45,820 The next one is target IP. 38 00:02:46,720 --> 00:02:48,970 After it comes the proper Mac. 39 00:02:49,120 --> 00:02:51,800 And lastly the target Mac. 40 00:02:51,880 --> 00:02:52,570 Here it is. 41 00:02:52,600 --> 00:02:58,780 Now let's see what we need to code right here in the first video of this section once we created the 42 00:02:58,780 --> 00:03:00,460 first malicious packet. 43 00:03:00,460 --> 00:03:04,870 We created it using an OPI footstool which is a response which is good. 44 00:03:04,870 --> 00:03:06,030 It should be like that. 45 00:03:06,160 --> 00:03:10,670 And we're going to do the same thing right here just right now instead of one packet. 46 00:03:10,690 --> 00:03:12,550 We're going to create two packets. 47 00:03:12,550 --> 00:03:17,650 One will be sent to the router and the other one will be sent to the Windows machine spoofing them both 48 00:03:17,740 --> 00:03:19,270 at the same time. 49 00:03:19,360 --> 00:03:26,320 So let's create a variable which will be called packet one the packet one will be a packet that we will 50 00:03:26,320 --> 00:03:28,870 determine to go to the router. 51 00:03:29,230 --> 00:03:30,250 So how can we do that. 52 00:03:30,250 --> 00:03:32,130 Most will simply create capital. 53 00:03:32,190 --> 00:03:38,050 Our packet as usual we send the OPI to be equal to since this is a response. 54 00:03:38,440 --> 00:03:44,530 And in order to to navigate this packet router we simply send the hardware destination to be equal to 55 00:03:44,540 --> 00:03:46,360 Router Mac. 56 00:03:46,690 --> 00:03:50,320 We also need to send a p destination to be equal to Router IP. 57 00:03:52,720 --> 00:03:53,350 Right here. 58 00:03:53,800 --> 00:03:57,660 And another thing that we need is going to be the source. 59 00:03:57,760 --> 00:04:04,570 Now before I actually type this before several create packet 2 which is going to be navigated through 60 00:04:04,570 --> 00:04:12,810 the windows 10 machine or to your own target machine which is not router or B has to be equal to 61 00:04:15,830 --> 00:04:22,940 hardware destination has to be equal to target Mac and it be destination has to be equal to target IP 62 00:04:23,690 --> 00:04:24,530 and P source. 63 00:04:24,530 --> 00:04:27,890 Once again we are going to leave empty right here. 64 00:04:28,220 --> 00:04:30,150 And the reason why we are leaving it empty. 65 00:04:30,170 --> 00:04:37,790 What do you think what should be the B source or the packet source in the first packet. 66 00:04:37,850 --> 00:04:42,710 Keep in mind that the B source is the IP address of the machine that is sending these packets so in 67 00:04:42,710 --> 00:04:46,520 our case that would be the IP address of the calisthenics machine. 68 00:04:47,420 --> 00:04:51,980 But we're not going to specify the IP address of the clinic's machine because then it would just be 69 00:04:52,010 --> 00:04:53,000 a regular packet. 70 00:04:53,000 --> 00:04:56,820 We want to create the malicious packet that will be able to spoof the connection. 71 00:04:56,870 --> 00:05:00,720 So what we need to specify right here is the target's IP. 72 00:05:01,550 --> 00:05:07,820 We want to send this package to the voter and make it seem as it came from the windows 10 machine. 73 00:05:08,000 --> 00:05:09,850 The same thing goes with the pack too. 74 00:05:09,890 --> 00:05:15,500 We want to send this back it to the Windows 10 machine and make it seem like it came from the router. 75 00:05:15,500 --> 00:05:18,900 Therefore in the packet tool we are specifying browser. 76 00:05:19,090 --> 00:05:27,890 I keep simple as that all we are left to do right now is send these two packets. 77 00:05:28,050 --> 00:05:37,870 So how can we do that well using the send function so scape it would send will first sent back one and 78 00:05:37,870 --> 00:05:43,420 then escape it'll send packets to write. 79 00:05:43,480 --> 00:05:46,850 Simple as that and our program is almost done. 80 00:05:46,930 --> 00:05:53,430 All we are left to add is right here under the while True loop below this pool function we want to add 81 00:05:53,430 --> 00:05:56,740 the small time out so it doesn't spoof too fast. 82 00:05:56,740 --> 00:06:04,180 We want to add kind of sleep let's sleep for two seconds between each and every packet that we sent. 83 00:06:04,420 --> 00:06:09,850 So we will send the ARP response demolishes our response every two seconds and we will keep the ARP 84 00:06:09,850 --> 00:06:15,370 tables updated with the incorrect MAC addresses to the router and we understand machine. 85 00:06:16,360 --> 00:06:18,390 So our program should be finished. 86 00:06:18,390 --> 00:06:21,830 Now let's test it and see how it works. 87 00:06:21,850 --> 00:06:30,820 If I open up my terminal right here clear the screen and type python on AARP's buffer and then I specify 88 00:06:30,940 --> 00:06:33,070 wanted to do that 168 at 1 1. 89 00:06:33,370 --> 00:06:39,480 So first goes the routers IP address and then one night to that 168 that one that too. 90 00:06:39,610 --> 00:06:42,630 This is the vendor's 10 IP address before we run it. 91 00:06:42,790 --> 00:06:48,190 Let's check once again the arc tables of this target machine. 92 00:06:48,460 --> 00:06:54,390 Let's also open a browser so we can see that we can connect to the Internet. 93 00:06:54,400 --> 00:06:55,660 OK so here is the browser. 94 00:06:55,690 --> 00:07:01,450 And every time we actually open this browser our connection goes through the router through this MAC 95 00:07:01,450 --> 00:07:04,340 address and then it retrieves this page back to us. 96 00:07:04,630 --> 00:07:11,600 And right now we're going to try to make this browser open the page while going to our Cal Linux machine. 97 00:07:12,590 --> 00:07:15,830 So let's run the program. 98 00:07:17,180 --> 00:07:19,970 It will print right here sent one packet. 99 00:07:19,970 --> 00:07:25,600 These are the packages that are being sent each and every two seconds as we specified right here. 100 00:07:25,610 --> 00:07:32,510 Now let's check the ARP tables on our of understand machine and we can see we successfully spoofed the 101 00:07:32,510 --> 00:07:34,160 MAC address of the voter. 102 00:07:34,160 --> 00:07:39,800 Now the Windows 10 machine things that the router is our clinic's machine and sends all the packets 103 00:07:39,920 --> 00:07:41,230 to us. 104 00:07:41,270 --> 00:07:46,520 Same goes with the router the router is also spoofed and sends all the packets that should go to the 105 00:07:46,520 --> 00:07:50,410 Windows 10 machine to overkill Linux machine. 106 00:07:50,440 --> 00:08:00,060 Now if we tried to go and open some page I clicked on a random website you will notice that it will 107 00:08:00,120 --> 00:08:01,920 load pretty long. 108 00:08:03,380 --> 00:08:09,410 Matter of fact in just a few seconds it will say that the actual connection cannot be established and 109 00:08:09,410 --> 00:08:11,840 it will not open this page. 110 00:08:11,840 --> 00:08:13,070 Now why is that. 111 00:08:13,070 --> 00:08:14,830 Well let me click X right here. 112 00:08:15,680 --> 00:08:21,340 If it closed this program right here there is one thing that we forgot to do. 113 00:08:21,560 --> 00:08:27,650 We successfully spoofed both of the targets but now we perform more of something like a boss attack 114 00:08:27,860 --> 00:08:31,630 on both of these targets as they cannot connect to the Internet anymore. 115 00:08:31,670 --> 00:08:38,530 That is because we are not forwarding packets from one target to another in order to be able to forward 116 00:08:38,530 --> 00:08:39,170 the packets. 117 00:08:39,190 --> 00:08:47,290 We need to run the command inside of our terminal which is Echo 1 and then these two arrows to right 118 00:08:47,920 --> 00:08:58,720 at this location so slash proc slash this slash net slash IP 4 and slash IP forward. 119 00:08:58,900 --> 00:09:02,670 Press your enter and if I run the program once again 120 00:09:06,850 --> 00:09:16,910 and try to load the website now it loads successfully we can load every website that we want if we want 121 00:09:16,910 --> 00:09:17,090 to. 122 00:09:17,090 --> 00:09:18,920 We can also go to Facebook dot com 123 00:09:23,990 --> 00:09:26,450 it will load all the pages without any problem. 124 00:09:26,570 --> 00:09:30,740 And on the vendor stand machine you will not notice anything out of order. 125 00:09:30,740 --> 00:09:35,660 You will most likely never know that you have been are spoofed and that someone can read all of your 126 00:09:35,660 --> 00:09:36,880 information. 127 00:09:36,950 --> 00:09:41,860 The only way that you can actually notice that if you simply just go to your command prompt and type 128 00:09:41,860 --> 00:09:48,760 the command are Dash 8 and you notice that two different IP addresses have same MAC address. 129 00:09:48,770 --> 00:09:52,850 This is a good indication that at the moment you are being spoofed. 130 00:09:52,970 --> 00:09:58,670 All right so we can see our article for works correctly now all the packets are going through our own 131 00:09:58,670 --> 00:10:00,800 machine and we can read them if we want to. 132 00:10:01,100 --> 00:10:03,830 But more about that in the later sections. 133 00:10:03,830 --> 00:10:09,710 When we code our own password sniffer then we are going to combine our arsenal for right here with the 134 00:10:09,710 --> 00:10:15,440 password sniffer and we are going to see how these two tools will combine in order for us to sniff the 135 00:10:15,440 --> 00:10:18,540 passwords that summer types in their browser. 136 00:10:18,560 --> 00:10:22,130 All right so that's about it for the section in the next video. 137 00:10:22,130 --> 00:10:27,470 Of course we are going to perform a small recap on this program and then we will proceed to the next 138 00:10:27,470 --> 00:10:28,690 project. 139 00:10:28,700 --> 00:10:30,750 Thank you for watching and take care. 140 00:10:30,800 --> 00:10:31,250 Bye.
