1 00:00:01,140 --> 00:00:07,180 In this lecture we're going to learn how to generate an undetectable backdoor about her is just a file 2 00:00:07,480 --> 00:00:10,390 that's when executed on the target computer. 3 00:00:10,400 --> 00:00:16,270 It'll give us full access to that computer so it'll basically allow us to hack it and do anything that 4 00:00:16,270 --> 00:00:18,460 we want on that computer. 5 00:00:18,460 --> 00:00:24,520 There is a number of ways to generate back doors and what we're interested in is to generate a backdoor 6 00:00:24,730 --> 00:00:28,190 that is not detectable by antivirus programs. 7 00:00:28,270 --> 00:00:34,690 Now this is not very hard to achieve as you'll see and we're going to do this using a tool called veil 8 00:00:34,690 --> 00:00:36,640 framework. 9 00:00:36,640 --> 00:00:43,150 Now first of all we have to install this tool and as usual to install tools on Debian on Carly. 10 00:00:43,150 --> 00:00:51,410 We have to first do up get update to update the list of packages that we can install and once this is 11 00:00:51,410 --> 00:00:58,940 done we're going to do apt get install followed by the package name that we want to install and we want 12 00:00:58,940 --> 00:01:05,630 to install a package called Will the IPL hit enter now. 13 00:01:05,750 --> 00:01:10,430 As you can see there are a lot of packages that need to be installed. 14 00:01:10,430 --> 00:01:12,610 So it's asking us Do we want to do this. 15 00:01:12,680 --> 00:01:18,710 I'm gonna type Y to continue and be patient with this because it's going to have to download all of 16 00:01:18,710 --> 00:01:23,420 these packages and then configure them and install them properly. 17 00:01:23,420 --> 00:01:28,630 Also if you get any errors please don't hesitate to ask us in the queue and a section. 18 00:01:28,640 --> 00:01:34,530 Show us a screenshot of the error and we'll try our best to help you. 19 00:01:34,810 --> 00:01:37,050 You might also get this as can you. 20 00:01:37,090 --> 00:01:43,900 If it's OK to restart packages while they're being upgraded so we're gonna say yes that's fine. 21 00:01:46,700 --> 00:01:52,840 Now that the installation is complete I'm going to clear the screen and I'm going to run the program. 22 00:01:53,000 --> 00:01:56,050 So the program is called VFL ville. 23 00:01:56,660 --> 00:02:03,140 We're going to have enter and because this is the first time we run the program it's going to automatically 24 00:02:03,140 --> 00:02:06,950 install all of the other dependencies. 25 00:02:06,950 --> 00:02:08,900 So it's asking me do I want to do this. 26 00:02:09,020 --> 00:02:10,060 And of course I do. 27 00:02:10,160 --> 00:02:16,660 So I'm going to type why so we can continue and again this process can take some time. 28 00:02:16,670 --> 00:02:20,420 So please be patient with it. 29 00:02:20,500 --> 00:02:24,790 It might seem like it's stuck in some of the stages but it's not. 30 00:02:24,790 --> 00:02:27,400 So just be patient with it and give it it's time 31 00:02:31,800 --> 00:02:36,030 one of the dependencies is a Windows Python interpreter. 32 00:02:36,030 --> 00:02:42,540 So we automatically see the installation wizard in here as you can see and all you have to do is literally 33 00:02:42,540 --> 00:02:51,580 just click on Next next next next to get it installed click on finish when it's done and here we have 34 00:02:51,670 --> 00:02:53,080 another dependency. 35 00:02:53,080 --> 00:03:00,490 Again all we're going to do with just next next next next and finish when it's done another one here. 36 00:03:00,490 --> 00:03:01,420 Same thing. 37 00:03:01,480 --> 00:03:05,350 Next next next and we're done 38 00:03:08,520 --> 00:03:11,140 Ruby four windows is another dependency. 39 00:03:11,340 --> 00:03:15,290 So again it's starting the installation wizard for it automatically here. 40 00:03:15,570 --> 00:03:22,460 All we have to do is select the language accept the terms and next next next. 41 00:03:22,470 --> 00:03:32,830 If it prompts you that the folder already exists you can just say yes and we're done with this although 42 00:03:32,830 --> 00:03:37,220 it is a script in language that's also a dependency as usual. 43 00:03:37,220 --> 00:03:44,530 Next agree next next next I'm just gonna uncheck this because I don't want to see the release notes 44 00:03:44,680 --> 00:03:48,470 and they're going to click on finish now. 45 00:03:48,480 --> 00:03:53,900 If you scroll up you'll see everything got installed properly for us except for the end. 46 00:03:53,910 --> 00:03:56,130 We're getting this error. 47 00:03:56,130 --> 00:04:00,330 This is an issue with the latest version of will of the installer. 48 00:04:00,360 --> 00:04:05,870 So hopefully they fix it in the future if they don't that's fine because the solution is really easy 49 00:04:06,210 --> 00:04:10,050 and the error itself is actually suggesting the solution for us. 50 00:04:10,410 --> 00:04:15,530 So the solution is simply to just copy this command right here and run it again. 51 00:04:15,540 --> 00:04:20,720 So I'm gonna paste it and hit enter okay. 52 00:04:20,730 --> 00:04:21,190 Perfect. 53 00:04:21,190 --> 00:04:23,080 Now we have no errors at all. 54 00:04:23,080 --> 00:04:30,580 And everything got installed properly so we're going to clear the screen one more time and again we're 55 00:04:30,580 --> 00:04:38,800 going to run the program by simply type in will the EIA El and as you can see the program is working 56 00:04:38,860 --> 00:04:45,920 with no issues at all now in the next lectures I'm gonna show you how to use this program to generate 57 00:04:46,010 --> 00:04:51,080 undetectable back doors that can be used to hack Windows computers.
