WEBVTT 00:00.270 --> 00:03.120 Alright now carry Linux Image Contents. 00:03.120 --> 00:07.850 Most common tools used in the field for penetration testing and team hacking. 00:08.780 --> 00:12.170 Now, however, it is not practical to include every single tool. 00:12.770 --> 00:13.240 All right. 00:13.250 --> 00:16.340 So for that, we will use the Aptx and Aptx. 00:16.340 --> 00:22.970 It is a set of tools that helps manage packages or applications on Debian based system. 00:23.510 --> 00:23.930 Okay. 00:23.930 --> 00:26.480 So the first thing that start with the aptx update. 00:26.750 --> 00:30.380 So we will use apt update command. 00:31.610 --> 00:34.430 Again, it will show us problem permission denied. 00:34.430 --> 00:36.050 We need to provide the sudo command. 00:36.060 --> 00:38.630 So sudo shift one, shift one as we learned previously. 00:39.170 --> 00:41.780 So sudo apt update press enter. 00:41.780 --> 00:47.150 So here it will start updating the repository and resources here. 00:47.510 --> 00:48.800 The resources list. 00:49.520 --> 00:50.720 Let's wait a little bit. 00:51.540 --> 00:52.500 Now it is done. 00:52.650 --> 00:57.200 Now here you can see that to list the upgradable command. 00:57.210 --> 01:01.080 So control shift C, control shift V as you can see. 01:01.680 --> 01:02.970 So press enter. 01:03.000 --> 01:08.190 It will show us everything that can be upgradable in the system and with the version. 01:08.430 --> 01:09.060 All right. 01:09.780 --> 01:12.360 You know, in my case, I didn't want to regret everything. 01:12.390 --> 01:15.020 I just want to operate some of them, for example. 01:15.030 --> 01:15.870 So. 01:16.690 --> 01:24.520 I will type sudo apt upgrade command or sub command oc and then choose the ones we want. 01:24.520 --> 01:26.500 So for example metasploit. 01:28.050 --> 01:29.310 That framework. 01:29.310 --> 01:32.940 And from where I get this, I get it from here. 01:32.940 --> 01:35.730 So if I scroll up a little bit, here it is. 01:35.730 --> 01:38.040 So Metasploit framework. 01:38.250 --> 01:38.910 All right. 01:38.910 --> 01:41.880 So just copy and paste that control shift, see? 01:43.140 --> 01:50.280 And delete this and but control shift v press enter it will start upgrading and it will tell you what 01:50.280 --> 01:53.420 it will install, what it will upgrade and all of that stuff. 01:53.430 --> 01:57.900 You know that it will start downloading 600 megabyte. 01:57.930 --> 01:58.950 I don't need that. 01:59.190 --> 02:00.610 To be honest for now. 02:00.630 --> 02:03.480 It will do the job so we learn how to upgrade. 02:04.390 --> 02:10.450 Either the whole system, by the way, upgrading the whole system just like this without providing any 02:10.450 --> 02:10.900 tool. 02:11.510 --> 02:13.480 Now, forget about the great. 02:13.510 --> 02:20.770 This is the great, which is the autocomplete from the Kelly Bash terminal behavior. 02:21.490 --> 02:27.490 So it will sudo apt upgrade as simple as that like this and it will start upgrading the whole system. 02:27.520 --> 02:32.280 Now what if I want to install a specific package that is not here? 02:32.320 --> 02:37.280 So for example, we don't have HP, so I want to install it. 02:37.300 --> 02:39.850 So as we learned sudo apt for now. 02:39.850 --> 02:43.120 Now not upgrade of course because hp is not here. 02:44.100 --> 02:48.420 The same thing not update to update the resources so it will be installed. 02:48.660 --> 02:52.530 So sudo apt install the hp and press enter. 02:53.130 --> 02:56.020 As you can see that the HP is already with the new way. 02:56.060 --> 02:59.820 So let's have another thing, not be my SQL. 02:59.820 --> 03:03.810 For example, as you can see, my school is not found. 03:04.110 --> 03:05.850 All right, so far, so good. 03:06.120 --> 03:08.250 Now, how to search for such a thing. 03:08.760 --> 03:12.150 Okay, in that case, I will use the search command. 03:12.150 --> 03:16.200 So sudo sudo apt search this time. 03:17.580 --> 03:19.980 My scan press enter. 03:20.010 --> 03:22.350 It will search for everything. 03:23.160 --> 03:28.260 For my school, as you can see, by phone, dash my school view or whatever. 03:28.290 --> 03:29.310 A lot of stuff. 03:30.190 --> 03:31.420 I noticed packages. 03:33.750 --> 03:35.590 So we can choose whatever we want. 03:35.610 --> 03:38.910 So, for example, this one or this one or whatever. 03:39.720 --> 03:46.050 Now, if I want my actual dash server press enter, you can see that this is the default core one, 03:46.050 --> 03:48.000 which is the default currency of our core. 03:48.030 --> 03:51.330 This is for my school server or default my school. 03:51.330 --> 03:53.640 I'll just copy and paste it. 03:53.640 --> 04:00.470 So sudo apt install and just copy and paste this for example and press enter. 04:00.480 --> 04:01.850 I don't need that for now. 04:01.860 --> 04:02.370 Okay. 04:02.400 --> 04:06.270 Now for example, actually let's have let's have it installed. 04:06.270 --> 04:07.980 So sudo apt. 04:08.550 --> 04:10.740 From here let's copy and paste that. 04:10.980 --> 04:16.350 Sudo apt install default may as well and it will start installing oc. 04:16.560 --> 04:19.590 And as you can see that the stalled and it is ready. 04:19.920 --> 04:26.910 Now what if I don't need this and I want to remove it so I want to install the other one which is this 04:26.910 --> 04:30.980 one, the default, my SQL Server, not the default, my SQL Server core. 04:31.000 --> 04:31.460 Okay. 04:31.470 --> 04:32.760 How to do such a thing? 04:32.760 --> 04:36.440 I will use this command sudo apt remove. 04:36.450 --> 04:43.320 By the way, you can see that we are using the app command and with sub commands install update upgrade 04:43.320 --> 04:46.200 list upgradable and remove. 04:46.200 --> 04:48.330 So remove search and remove. 04:48.330 --> 04:53.220 So remove and just put the name of the package and let's remove it. 04:53.250 --> 04:54.390 It will ask me. 04:54.390 --> 04:59.160 Yeah, after this operation, ten kilobytes of that, this could be freed. 04:59.190 --> 05:00.120 PRESS Yes. 05:00.270 --> 05:03.360 And you can see that now it has been removed. 05:03.660 --> 05:04.790 All right, cool. 05:04.800 --> 05:05.840 So far, so good. 05:05.850 --> 05:13.290 Now, by the way, sometimes this doesn't remove everything just to remove the pointer or some. 05:14.350 --> 05:15.040 Dependencies. 05:15.040 --> 05:19.900 But if you want to remove everything, you need to put dash, dash, command. 05:19.900 --> 05:23.710 But be aware and be cautious while using the purge. 05:23.710 --> 05:28.280 Because the purge, it will remove everything related to this package. 05:28.330 --> 05:29.830 So if I press enter. 05:30.740 --> 05:34.220 You can see that by the way, it is already installed. 05:34.310 --> 05:36.850 Sorry, and installed and removed. 05:36.860 --> 05:38.840 So yeah, nothing to be removed. 05:39.410 --> 05:43.610 Now again, I'm telling you that on a production system, not on the server. 05:44.620 --> 05:48.490 Not on the Linux system because in Linux we don't care. 05:49.290 --> 05:52.440 We want things to be running and to start. 05:53.220 --> 05:54.540 Attacking the systems. 05:54.810 --> 05:55.350 All right. 05:55.920 --> 06:01.500 Because after all, we are looking from the perspective of a red team, not the blue team here. 06:01.530 --> 06:05.820 Now, finally, we have another thing, which is the DD package. 06:05.850 --> 06:06.500 Okay. 06:06.690 --> 06:09.460 Now, this is not using the APT. 06:09.510 --> 06:15.810 So if I type it here, this is a package manager for Debian as you can see D which means debian bug. 06:15.840 --> 06:17.410 So which means packages. 06:17.430 --> 06:18.060 All right. 06:18.060 --> 06:25.680 So sudo the package we will use dash I command which which means installed and what the name of the 06:25.680 --> 06:27.930 package for example test dot. 06:29.440 --> 06:30.190 DB the. 06:31.060 --> 06:38.410 Now this is just a test now not something to be installed, but I can, for example if I want to install 06:38.470 --> 06:45.340 specific packages from the internet for Python, for BHP, my school or whatever, and I don't need 06:45.340 --> 06:46.060 to use the app. 06:46.390 --> 06:48.340 I want it to be installed. 06:48.340 --> 06:49.840 The Debian file. 06:50.410 --> 06:53.740 So after I install it, for example, its name is test. 06:53.860 --> 06:55.770 So sudo de package dash. 06:55.780 --> 07:00.400 I install this package which is the package and it will start install. 07:00.490 --> 07:01.080 Alright. 07:01.090 --> 07:01.890 Okay, cool. 07:01.900 --> 07:02.920 So far so good.
