WEBVTT 00:01.280 --> 00:05.320 Okay, now we have this little program. 00:06.320 --> 00:07.320 Extract from. 00:07.440 --> 00:09.400 Now I'm going to ignore this for now. 00:09.520 --> 00:12.280 And I'm going to do one more thing. 00:12.280 --> 00:19.320 And that is to create a program that can this program, this website, for example, and extract everything 00:19.320 --> 00:24.120 we need and then check for vulnerabilities. 00:24.160 --> 00:29.920 And we are going to do that in this section in Vulnerability Scanner. 00:30.760 --> 00:33.720 So in here I'm going to create two new files. 00:33.720 --> 00:35.360 One of them is going to be scanner. 00:37.520 --> 00:41.040 The next one is going to be Vulnerability scanner. 00:41.080 --> 00:41.520 Okay. 00:44.960 --> 00:46.280 What happened. 00:53.680 --> 00:54.400 Okay. 00:54.400 --> 00:55.400 It is going to be. 01:04.890 --> 01:10.450 Into this scanner file, I am going to add a lot of files. 01:10.530 --> 01:11.850 All the files here. 01:12.730 --> 01:16.010 And then in vulnerability scanner we are going to call. 01:16.010 --> 01:20.530 We are going to this use this scanner to execute our code. 01:20.570 --> 01:21.010 Okay. 01:24.050 --> 01:27.490 So first let's create a class. 01:27.730 --> 01:30.650 I'm going to name this class scanner. 01:31.890 --> 01:34.490 And here we had something. 01:34.530 --> 01:38.330 Let me find that. 01:38.370 --> 01:39.570 Not this one. 01:41.130 --> 01:41.530 Okay. 01:41.770 --> 01:49.050 We need this traveler 2.py because right here it is checking for a URL. 01:49.090 --> 01:49.730 Okay. 01:49.730 --> 01:54.970 And then it is checking it is searching for all the links. 01:54.970 --> 01:58.090 And it is finding it and then printing that to me. 01:58.610 --> 02:03.410 So in here I need to use this. 02:03.570 --> 02:04.010 Okay. 02:08.270 --> 02:09.790 Let's copy this. 02:09.990 --> 02:10.750 And. 02:14.190 --> 02:18.030 Let me copy this from here up to here we have two method here. 02:18.830 --> 02:24.590 And let's put that boot method inside this class. 02:26.030 --> 02:28.910 And in this class because it is a class. 02:28.910 --> 02:32.830 So it is going to be kind of different. 02:32.870 --> 02:33.270 Okay. 02:34.750 --> 02:40.870 So in here we need to create a constructor. 02:40.870 --> 02:43.670 You know how you define a constructor. 02:43.710 --> 02:44.110 Okay. 02:44.470 --> 02:48.230 So we use this keyword and then init. 02:52.670 --> 02:56.670 And we remove some of this thing from here. 02:59.590 --> 03:03.830 And then inside this uh in here we can give. 03:06.590 --> 03:08.470 All the arguments that we need. 03:08.630 --> 03:12.520 So the first argument that I am going to add is going to be the URL. 03:12.880 --> 03:13.160 Okay. 03:13.200 --> 03:15.880 Let's URL. 03:17.240 --> 03:27.720 And here inside this I am going to access this URL and change the name of URL to something else. 03:27.720 --> 03:30.400 Let's use this self dot. 03:30.840 --> 03:32.720 I'm going to change it to target. 03:34.280 --> 03:36.840 URL is going to be equal to URL. 03:37.280 --> 03:44.400 So whenever someone use target URL that means they are going to access this URL that is here. 03:46.080 --> 03:55.720 The next thing that we need to handle is that inside this extract link we need to add the self keyword 03:55.720 --> 03:56.160 here. 03:56.960 --> 04:04.360 Now because we have because it is inside the class, we need to use self keyword here. 04:04.640 --> 04:07.520 And then we have the request here. 04:07.520 --> 04:10.480 That means we need to import request. 04:10.520 --> 04:11.480 Okay. 04:11.520 --> 04:19.570 Import Requests and the next thing we have our e here means regex. 04:19.690 --> 04:21.730 We need to import our e as well. 04:24.610 --> 04:25.050 Okay. 04:27.770 --> 04:32.650 We have response which is equal to request dot get and then the url. 04:33.450 --> 04:34.930 Then we are returning here. 04:37.610 --> 04:38.810 Everything looks good. 04:39.570 --> 04:42.530 So this part is done now. 04:42.530 --> 04:48.930 Now it is time to come here inside the travel and check for this. 04:48.930 --> 04:50.290 We need a lot of things here. 04:50.290 --> 04:53.250 One of them is extract link that is here. 04:53.250 --> 05:03.690 As you see we have the extract link that is saying that it is not defined because before it was defined 05:03.690 --> 05:08.330 because we were out of the class, we were not using class and constructor. 05:08.330 --> 05:13.290 But now that we are using it, we need to use something else here. 05:16.870 --> 05:18.070 That is self okay. 05:25.950 --> 05:28.510 Self dot extract link. 05:29.710 --> 05:37.430 And also here inside these travel method we need to add the self as well. 05:37.470 --> 05:40.230 Okay now that is solved. 05:40.230 --> 05:42.790 But as you see we have URL join here. 05:43.110 --> 05:47.710 That is a library that we need to use it okay. 05:47.710 --> 05:48.590 And that is here. 05:48.590 --> 05:58.270 We need to import that from here just like this I will copy this and use it up here because it is very 05:58.270 --> 06:01.630 easy to copy and paste something. 06:01.630 --> 06:06.270 So now it is also solved and we have the target link here. 06:06.270 --> 06:10.990 Let's see what I have, what I have done about this. 06:10.990 --> 06:12.750 You see we have the target link here. 06:12.870 --> 06:17.390 And you see that I defined the target link right here. 06:17.390 --> 06:22.840 And you see it is an empty List and I need to handle that. 06:22.920 --> 06:24.040 The same thing here. 06:25.200 --> 06:33.200 Inside the constructor and in the constructor I need to define that. 06:33.200 --> 06:39.920 So self the dot target underscore. 06:40.680 --> 06:42.080 We have the URL. 06:42.560 --> 06:44.600 This time it is going to be link. 06:44.640 --> 06:48.120 It is equal to an empty string an empty list. 06:49.040 --> 06:51.040 Target link. 06:53.040 --> 06:53.440 Okay. 06:54.360 --> 06:55.960 Now we have that as well. 06:58.480 --> 07:02.720 And as you see right now it is giving me the kind of error. 07:02.760 --> 07:03.640 Here you see. 07:05.040 --> 07:10.720 And to solve this to use that you need to use self keyword as well here. 07:11.000 --> 07:14.760 And also the same thing here. 07:17.480 --> 07:22.040 Self dot target link happened. 07:22.930 --> 07:23.650 Okay. 07:23.650 --> 07:30.130 And also when you call this method here, inside here you need to use the self keyword. 07:30.130 --> 07:31.210 The same thing here. 07:31.250 --> 07:31.610 Okay. 07:32.330 --> 07:41.170 So now uh, it is almost complete that we need to complete the vulnerability scanner here. 07:41.490 --> 07:45.410 We need to call this scanner inside this file. 07:45.410 --> 07:47.010 And we need to use it okay. 07:53.410 --> 07:55.130 Um okay. 07:55.130 --> 07:56.810 We have the URL here. 07:56.810 --> 08:00.330 We have the target link here target URL and target link. 08:00.370 --> 08:01.890 We have two things here okay. 08:02.650 --> 08:07.490 And in here I need to first import the the file okay. 08:07.530 --> 08:09.730 So let's use import scanner. 08:10.330 --> 08:14.770 And the next thing is that we need is the target URL. 08:17.250 --> 08:20.890 So this target URL is equal to the URL that we want. 08:20.890 --> 08:26.660 And the next thing that I want is to create an object from this Is a scanner. 08:26.700 --> 08:29.700 I'm going to name it one scanner. 08:30.940 --> 08:34.060 It is equal to scanner dot. 08:35.300 --> 08:36.820 Let's see. 08:36.820 --> 08:38.100 We have the class here. 08:38.100 --> 08:38.540 You see. 08:38.580 --> 08:39.380 Okay. 08:39.420 --> 08:40.980 That is must be capital. 08:41.220 --> 08:42.980 Let's see if it is capital or not. 08:43.020 --> 08:44.740 Of course it is capital. 08:45.500 --> 08:50.340 And now that we are going to create its object. 08:51.100 --> 09:00.620 And in here into the constructor, you see we have only one argument and that is URL or target URL. 09:00.660 --> 09:01.100 Okay. 09:01.500 --> 09:08.740 So we need to provide it here I am going to name it target URL or give the target URL that is here. 09:09.580 --> 09:15.700 The next thing is that we need to call the function or the method that is called gravel okay. 09:17.540 --> 09:18.180 And. 09:20.580 --> 09:23.780 That is going to be in here. 09:24.220 --> 09:35.320 So we have its object that is called wall scanner dot Gravel and it is going to get the URL. 09:35.320 --> 09:38.520 And right now it is going to be the target URL. 09:38.560 --> 09:38.960 Okay. 09:39.280 --> 09:44.200 Now I'm going to save this and let's give a URL to this. 09:45.360 --> 09:47.160 And it is going to be. 09:49.200 --> 09:49.880 This one. 09:49.920 --> 09:57.720 So use Ctrl C here and use Ctrl V in here Matilda. 09:57.760 --> 09:59.640 Okay let's save it. 09:59.640 --> 10:01.840 And also let's come here. 10:01.840 --> 10:05.320 Use Ctrl S to save that as well. 10:06.920 --> 10:11.400 And here let's use Clear and Python. 10:11.400 --> 10:15.880 We have vulnerability scanner dot p y and then hit enter. 10:15.920 --> 10:23.160 As you see it is working perfectly and it is scanning for all the links and whatever we need okay. 10:23.200 --> 10:29.400 And finally we get all the link links that we need and it is working perfectly. 10:29.440 --> 10:32.680 So let's go and improve this in the next lecture.
