1 1 00:00:00,090 --> 00:00:01,600 Now in the next lectures, 2 2 00:00:01,600 --> 00:00:05,280 we're gonna start talking about server side attacks. 3 3 00:00:05,280 --> 00:00:07,210 I'm gonna teach you what a server is, 4 4 00:00:07,210 --> 00:00:09,660 and we're gonna talk about that in details. 5 5 00:00:09,660 --> 00:00:11,710 But before we jump into this, 6 6 00:00:11,710 --> 00:00:14,530 we need to have a computer or a machine 7 7 00:00:14,530 --> 00:00:19,530 that acts as a server so that we can try to hack into it. 8 8 00:00:19,580 --> 00:00:22,400 So similar to the way that we had a Window's machine 9 9 00:00:22,400 --> 00:00:26,500 to practice attacks that we can launch against normal users, 10 10 00:00:26,500 --> 00:00:28,840 we need to have another virtual machine 11 11 00:00:28,840 --> 00:00:31,090 that behaves like a server, 12 12 00:00:31,090 --> 00:00:34,490 so that we can practice server side attacks against it, 13 13 00:00:34,490 --> 00:00:37,183 and see how we can hack into servers. 14 14 00:00:38,240 --> 00:00:39,770 So the machine that we're gonna use 15 15 00:00:39,770 --> 00:00:43,370 is called Metasploitable and it's a virtual machine 16 16 00:00:43,370 --> 00:00:45,010 that's built on Linux. 17 17 00:00:45,010 --> 00:00:47,870 And it contains a number of services 18 18 00:00:47,870 --> 00:00:51,130 that's typically used by servers. 19 19 00:00:51,130 --> 00:00:54,160 It also contains a number of web applications 20 20 00:00:54,160 --> 00:00:57,660 that act exactly like normal web applications 21 21 00:00:57,660 --> 00:01:01,430 and use the same technologies used by normal servers 22 22 00:01:01,430 --> 00:01:04,100 and normal web applications, 23 23 00:01:04,100 --> 00:01:06,210 so we're gonna install this machine. 24 24 00:01:06,210 --> 00:01:07,700 And then in the future, 25 25 00:01:07,700 --> 00:01:09,800 we're gonna use it as a target 26 26 00:01:09,800 --> 00:01:12,060 to learn how to hack into servers, 27 27 00:01:12,060 --> 00:01:15,330 and how to hack into websites. 28 28 00:01:15,330 --> 00:01:17,880 You can download this from the following link. 29 29 00:01:17,880 --> 00:01:20,610 Now, I've also included this link in the resources 30 30 00:01:20,610 --> 00:01:21,690 of this lecture, 31 31 00:01:21,690 --> 00:01:25,780 which you can access from the top left of each lecture. 32 32 00:01:25,780 --> 00:01:27,230 If you click on this link, 33 33 00:01:27,230 --> 00:01:28,680 you'll get this page 34 34 00:01:28,680 --> 00:01:32,320 which will allow you to download Metasploitable 35 35 00:01:32,320 --> 00:01:33,900 Before you can download it, 36 36 00:01:33,900 --> 00:01:36,950 you're gonna have to fill your information in here. 37 37 00:01:36,950 --> 00:01:39,710 So I'm just gonna fill up anything for a company 38 38 00:01:39,710 --> 00:01:41,743 and anything for a phone number. 39 39 00:01:42,880 --> 00:01:44,800 Now, one thing I'd like to note 40 40 00:01:44,800 --> 00:01:46,980 when it asks you for your email, 41 41 00:01:46,980 --> 00:01:50,250 if you use a normal Gmail account like this one 42 42 00:01:50,250 --> 00:01:51,740 and tries to download 43 43 00:01:52,840 --> 00:01:54,510 you'll see that it's gonna say, 44 44 00:01:54,510 --> 00:01:57,163 this must be a valid company email. 45 45 00:01:58,080 --> 00:02:00,270 So if you do not have a company 46 46 00:02:00,270 --> 00:02:02,840 you can use a fake email in here, 47 47 00:02:02,840 --> 00:02:05,720 all you have to do is just write a name 48 48 00:02:05,720 --> 00:02:08,070 at any company name you want. 49 49 00:02:08,070 --> 00:02:12,633 So I'm just gonna say is Zaid@imaginarcompany.com. 50 50 00:02:13,570 --> 00:02:16,090 Now don't use imaginary company as well, 51 51 00:02:16,090 --> 00:02:17,700 because I don't want a lot of people 52 52 00:02:17,700 --> 00:02:19,970 using the same fake email. 53 53 00:02:19,970 --> 00:02:22,680 But the idea is you just wanna use a name 54 54 00:02:22,680 --> 00:02:25,210 at some other name.com. 55 55 00:02:25,210 --> 00:02:27,750 And this will allow you to bypass all of this. 56 56 00:02:27,750 --> 00:02:30,250 And once you click on submit, 57 57 00:02:30,250 --> 00:02:32,130 you go to the download page. 58 58 00:02:32,130 --> 00:02:35,410 And if we click on download Metasploitable now, 59 59 00:02:35,410 --> 00:02:37,053 it'll download it for me. 60 60 00:02:38,350 --> 00:02:39,960 Now, once it's downloaded, 61 61 00:02:39,960 --> 00:02:41,830 you're gonna have a zip file. 62 62 00:02:41,830 --> 00:02:43,710 And I've already downloaded this. 63 63 00:02:43,710 --> 00:02:46,273 So I have the zip file right here. 64 64 00:02:47,220 --> 00:02:49,180 Sorry, not this one, like this one. 65 65 00:02:49,180 --> 00:02:50,750 So once you uncompressed it, 66 66 00:02:50,750 --> 00:02:52,780 you'll get this directory 67 67 00:02:52,780 --> 00:02:56,860 double click it and you'll see the following files. 68 68 00:02:56,860 --> 00:02:58,620 So we're gonna create a new machine here, 69 69 00:02:58,620 --> 00:03:02,363 in virtual machine and I'm gonna call it Metasploitable. 70 70 00:03:05,100 --> 00:03:07,323 And this is going to be a Linux machine. 71 71 00:03:09,580 --> 00:03:12,030 And I'm gonna hit continue along, 72 72 00:03:12,030 --> 00:03:14,500 and I'll only gonna give it a gigabyte of RAM 73 73 00:03:14,500 --> 00:03:15,350 should be enough. 74 74 00:03:18,310 --> 00:03:21,210 And then I'm gonna use remember with Kali Linux, 75 75 00:03:21,210 --> 00:03:23,630 we created a new virtual hard disk. 76 76 00:03:23,630 --> 00:03:26,390 With this, we're gonna use an existing one. 77 77 00:03:26,390 --> 00:03:28,563 The reason for that is because, 78 78 00:03:29,510 --> 00:03:32,010 the image that we have right now is actually 79 79 00:03:32,010 --> 00:03:34,250 it's designed for VMware Player. 80 80 00:03:34,250 --> 00:03:36,600 So what we're going to do is we're gonna import 81 81 00:03:37,630 --> 00:03:40,990 the hard disk file or the hard disk image in here, 82 82 00:03:40,990 --> 00:03:43,370 so that we're gonna have an already installation 83 83 00:03:43,370 --> 00:03:44,950 without having to install it, 84 84 00:03:44,950 --> 00:03:47,160 the way we installed Kali Linux. 85 85 00:03:47,160 --> 00:03:50,513 So we're just gonna use an existing virtual hard disk file. 86 86 00:03:51,520 --> 00:03:53,040 And I'm just gonna navigate, 87 87 00:03:53,040 --> 00:03:54,530 to select what it is. 88 88 00:03:54,530 --> 00:03:57,560 I'm gonna go into the Metasploitable directory 89 89 00:03:57,560 --> 00:04:02,250 and I'm gonna select the .VMDK file. 90 90 00:04:02,250 --> 00:04:04,003 So it's this file right here. 91 91 00:04:04,980 --> 00:04:09,980 I'm gonna click on open, and create. 92 92 00:04:12,030 --> 00:04:14,493 So we're gonna start this machine right now. 93 93 00:04:17,330 --> 00:04:20,360 Okay, so the machine has run now it's completely installed. 94 94 00:04:20,360 --> 00:04:22,440 As I said, you don't really need to install anything, 95 95 00:04:22,440 --> 00:04:25,890 we just imported a ready installation already hard disk. 96 96 00:04:25,890 --> 00:04:28,400 So it's asking me for the username, 97 97 00:04:28,400 --> 00:04:30,033 and the username is msfadmin. 98 98 00:04:33,561 --> 00:04:37,100 And the password is the same, so it's msfadmin as well. 99 99 00:04:37,100 --> 00:04:40,820 Now you might notice once you start typing the password, 100 100 00:04:40,820 --> 00:04:44,060 you'll see nothing displayed on screen. 101 101 00:04:44,060 --> 00:04:45,950 This is a security feature 102 102 00:04:45,950 --> 00:04:50,330 so that the password is not visible to people beside you. 103 103 00:04:50,330 --> 00:04:52,790 So once you get asked for the password, 104 104 00:04:52,790 --> 00:04:56,430 type msfadmin, and then hit enter. 105 105 00:04:56,430 --> 00:04:58,460 Now I've actually already typed it. 106 106 00:04:58,460 --> 00:05:02,860 So now when I hit Enter You'll see it's gonna log me in. 107 107 00:05:02,860 --> 00:05:05,900 Now this machine already has a terminal interface, 108 108 00:05:05,900 --> 00:05:07,800 as you can see here. 109 109 00:05:07,800 --> 00:05:09,010 And it's giving you a warning 110 110 00:05:09,010 --> 00:05:11,930 that you should never expose this machine 111 111 00:05:11,930 --> 00:05:13,750 to external internet connection 112 112 00:05:13,750 --> 00:05:15,720 because it is a vulnerable machine 113 113 00:05:15,720 --> 00:05:17,420 it is designed to be vulnerable. 114 114 00:05:17,420 --> 00:05:20,290 Now, right now it's only inside our lab, 115 115 00:05:20,290 --> 00:05:22,800 it's on the installed as virtual machine. 116 116 00:05:22,800 --> 00:05:25,900 So literally nobody outside our lab can access it. 117 117 00:05:25,900 --> 00:05:29,070 So this is a really good way of using it. 118 118 00:05:29,070 --> 00:05:31,140 Now this is if the machine is installed. 119 119 00:05:31,140 --> 00:05:32,410 As I said in the future, 120 120 00:05:32,410 --> 00:05:35,380 we're gonna talk about how we're gonna try 121 121 00:05:35,380 --> 00:05:36,730 and hack into this machine. 122 122 00:05:36,730 --> 00:05:38,840 Again, don't be intimidated by the terminal. 123 123 00:05:38,840 --> 00:05:40,170 We're gonna be using it a lot 124 124 00:05:40,170 --> 00:05:43,620 and we're gonna learn how to use it step by step. 125 125 00:05:43,620 --> 00:05:46,090 So at the moment, just we have this installed, 126 126 00:05:46,090 --> 00:05:47,850 and we're gonna move on to the next step. 127 127 00:05:47,850 --> 00:05:49,560 And we will talk about this, 128 128 00:05:49,560 --> 00:05:52,170 once we actually need to use it in the future. 129 129 00:05:52,170 --> 00:05:53,560 So if you wanna turn off this machine, 130 130 00:05:53,560 --> 00:05:57,453 all you have to do is just typing power off and hit Enter. 131 131 00:05:59,830 --> 00:06:01,570 I was telling you that you need to be root. 132 132 00:06:01,570 --> 00:06:04,140 So, again, I'll talk about this later 133 133 00:06:04,140 --> 00:06:05,793 for now sudo power off. 134 134 00:06:07,670 --> 00:06:09,423 So just run the command like this. 135 135 00:06:11,290 --> 00:06:13,483 And it's asking you for the admin password. 136 136 00:06:16,140 --> 00:06:17,840 And that's it, it's going off now. 137 137 00:06:19,300 --> 00:06:21,050 And here we go, the machine is off.
