WEBVTT 00:00.680 --> 00:01.280 Hi. 00:01.320 --> 00:02.120 Welcome back. 00:02.680 --> 00:06.400 Now let's explain something which is very important. 00:06.400 --> 00:11.680 And that is about domain and also sub domain and main domain. 00:12.160 --> 00:15.520 So it is very important to learn what is domain. 00:15.520 --> 00:16.960 What is the main domain. 00:16.960 --> 00:19.080 How can we access them. 00:19.080 --> 00:28.520 And also how to create a program to get this domain and also sub domains and the domain. 00:28.520 --> 00:31.960 For example this google.com, it is a domain okay. 00:32.000 --> 00:36.200 And everyone knows that it is the main domain okay. 00:36.240 --> 00:38.280 And also it has some sub domain. 00:38.280 --> 00:40.680 For example this Google has a lot of things. 00:40.680 --> 00:45.480 For example it has a mail and also it has social media. 00:45.480 --> 00:48.640 It has a lot of things okay that people are using. 00:48.640 --> 00:51.680 For example, it has Google Drive and a lot of things. 00:51.720 --> 00:53.120 Okay. 00:53.160 --> 00:57.120 And here let me show you for example this is the main domain. 00:57.120 --> 01:02.540 And also if you want to get one of the one of its sub domain, it is I think. 01:02.740 --> 01:04.460 Mail.google.com. 01:04.820 --> 01:09.860 Now, if I hit enter, you will see that now we get this Mail.google.com. 01:09.860 --> 01:15.380 And also you see that it has changed to Gmail slash vote and blah blah blah. 01:15.420 --> 01:22.340 Okay, so we need to create a program that git we give the main domain okay. 01:22.380 --> 01:26.020 And also some subdomain that we are testing. 01:26.060 --> 01:32.100 For example we give google.com and then we give the other thing like Gmail like mail.google.com. 01:32.100 --> 01:35.500 We need to have uh okay. 01:35.660 --> 01:45.180 Or to go to hundred or even print for me or for us that this domain exists and it is very good because 01:45.220 --> 01:55.740 in some cases we are going to find some, some sub domain of a main website that they are, for example, 01:55.780 --> 02:01.860 it is a light part or a light version of that website, and they're still testing something on that. 02:01.860 --> 02:03.930 And we And we can hack them very easily. 02:03.970 --> 02:04.490 Okay. 02:04.530 --> 02:07.690 So we need to get subdomain of the main domains. 02:08.090 --> 02:08.690 So it is good. 02:08.730 --> 02:09.810 Okay. 02:09.810 --> 02:15.250 Now if I came back here you see I created something called cobbler dot pi. 02:15.290 --> 02:19.450 It is a, uh, just a website. 02:19.490 --> 02:19.890 Okay. 02:20.570 --> 02:21.410 Let me go to. 02:23.650 --> 02:25.650 Set a document. 02:27.890 --> 02:31.290 And we have. 02:31.290 --> 02:31.850 Okay. 02:31.890 --> 02:34.930 Python for ethical hacking. 02:34.930 --> 02:39.290 And also we have, uh, website hacking. 02:39.530 --> 02:41.730 Okay, good. 02:42.170 --> 02:46.490 Now, I'm in this position or in this part. 02:48.250 --> 02:48.610 Okay. 02:49.490 --> 02:56.610 So for getting access to website and also getting information from a website, we are going to use a 02:56.610 --> 02:58.170 module called request. 02:58.210 --> 02:58.690 Okay. 02:59.290 --> 03:04.710 Um, this request, uh, we already used use this in some cases. 03:04.950 --> 03:06.270 Now you know how to use it. 03:06.270 --> 03:07.590 So let's import this. 03:08.950 --> 03:09.950 Requests. 03:11.030 --> 03:17.030 And first let's create a variable I'm going to name this URL. 03:17.070 --> 03:17.790 Okay. 03:17.790 --> 03:31.310 So this URL is going to be for example um google.com okay so here I am going to use a request and also 03:31.350 --> 03:33.750 the get method to get access to this. 03:33.750 --> 03:38.230 So let's use get response. 03:40.750 --> 03:43.190 It's going to be equal to request. 03:45.310 --> 03:46.990 Dot get method. 03:46.990 --> 03:56.230 So this get method will get will try to access the URL that we are providing for this for example google.com 03:56.350 --> 03:58.510 and also something else. 03:58.510 --> 04:05.210 So here I'm going to um I'm going to give something else. 04:05.210 --> 04:14.290 For example, we are having this here and in here I need to provide HTTP. 04:16.650 --> 04:21.610 And I'm going to concatenate this with the URL that we have it okay. 04:22.210 --> 04:26.050 Now if I print this Get response. 04:28.570 --> 04:34.530 And you see we have WWE google.com. 04:34.530 --> 04:44.410 And if I execute this program now and it tries to get access to this website, if it gets access, if 04:44.410 --> 04:45.170 that exists. 04:45.170 --> 04:48.170 So this will give me a code. 04:48.210 --> 05:01.210 A response code of 200 200 means okay so let's use Python and we have our.py. 05:01.250 --> 05:02.250 Now I hit enter. 05:02.250 --> 05:09.750 It is trying to access that and you see that we get a response code of 403. 05:09.790 --> 05:13.510 That means it is not able to access this thing. 05:13.550 --> 05:14.510 Okay. 05:14.510 --> 05:14.750 So. 05:17.790 --> 05:18.990 Let's remove this. 05:21.390 --> 05:24.470 And now I'm going to try once again. 05:25.510 --> 05:26.190 Let's see. 05:27.190 --> 05:33.310 And still you see that we are not able to get access to this one. 05:33.350 --> 05:34.310 Okay. 05:34.310 --> 05:36.790 What if I use https. 05:41.950 --> 05:45.670 You see a response code of 403. 05:45.990 --> 05:48.790 That means we are not able to access. 05:51.030 --> 05:57.630 Now, this, uh, 403 means that it is accessible. 05:57.670 --> 05:57.990 Okay. 05:58.030 --> 06:01.150 But it is forbidden now because of that. 06:01.310 --> 06:05.980 And you may know that in Iran, Everything is filtered. 06:05.980 --> 06:06.380 Okay? 06:06.420 --> 06:06.940 All. 06:06.940 --> 06:09.740 And the whole internet is filtered. 06:10.060 --> 06:12.220 They are forbidden in Iran. 06:12.380 --> 06:16.820 So because of that, now I'm not able to get the response code of 200. 06:17.140 --> 06:24.820 Now, for example, if I try to get access to an Iranian website and you will see that I will get a 06:24.860 --> 06:26.860 code 200. 06:28.140 --> 06:31.100 And if I try to do with a website like. 06:33.260 --> 06:35.660 Shaken dot air. 06:36.220 --> 06:44.260 Now if this website exists and I would be able to access it, I will get 200. 06:44.300 --> 06:48.340 And if it is not exist then I will get an error. 06:48.780 --> 06:50.580 Let's try to access this. 06:54.500 --> 06:54.740 Uh. 06:54.740 --> 06:55.460 Let's see. 06:57.940 --> 06:59.620 We have shaken dot air. 06:59.660 --> 07:00.060 Okay. 07:01.020 --> 07:02.260 You see that? 07:02.260 --> 07:04.140 It gives me this kind of error. 07:04.180 --> 07:06.680 That means this is not exist. 07:06.680 --> 07:06.960 Okay? 07:06.960 --> 07:08.040 This chicken air. 07:08.440 --> 07:12.360 Now, if I came back here, we have its URL here. 07:12.680 --> 07:15.000 Let me copy the whole thing from here. 07:16.120 --> 07:21.720 So I copy this and you see instead of C I used k. 07:21.760 --> 07:23.440 It is an Iranian website okay. 07:23.480 --> 07:25.760 That is breaking the filters. 07:28.760 --> 07:39.760 And here now if I use that website here and remove this part because I use that here and I save it. 07:41.440 --> 07:42.600 Let's clear this. 07:45.760 --> 07:46.560 And hit enter. 07:46.560 --> 07:48.960 Now you see that I get code 200. 07:49.000 --> 07:52.480 That means I am able to get access to this one. 07:52.520 --> 07:53.240 Okay. 07:53.240 --> 08:03.600 And if I try something else for example, to get its, um, sub domain, I will be able to get that. 08:03.600 --> 08:03.920 Okay. 08:03.960 --> 08:06.360 So I will explain that in the next lecture.
