Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated: 1 00:00:00,270 --> 00:00:03,360 Now that you've seen that you might be thinking wow that was too easy. 2 00:00:03,660 --> 00:00:06,540 That's all it takes to install and remove packages of Linux. 3 00:00:06,540 --> 00:00:09,140 I don't even have to go to the Internet and find them. 4 00:00:09,280 --> 00:00:10,840 Just find them for me. 5 00:00:11,280 --> 00:00:11,610 Yes. 6 00:00:11,610 --> 00:00:16,070 Is that something that you might notice wondering but what do these packages come from. 7 00:00:16,260 --> 00:00:21,660 How does candy or anything else for that matter know where to go and look for these packages. 8 00:00:21,880 --> 00:00:28,380 They look in something called depositories and depositories are storage locations from which your software 9 00:00:28,380 --> 00:00:30,960 packages can be retrieved and installed. 10 00:00:31,790 --> 00:00:37,360 So Gadi for example or Debian or anything else for that matter it would have the most storage location 11 00:00:38,590 --> 00:00:46,030 once you issue the ABT get command your Linux box will go into that location try and find the package 12 00:00:46,100 --> 00:00:49,930 and if it does it will download it and install it for you. 13 00:00:50,710 --> 00:00:57,310 However sometimes you try to install the baggage and Kelly can't find it and the default repositories. 14 00:00:57,400 --> 00:01:02,320 So what do you do first let's have a look at what these things look like. 15 00:01:02,320 --> 00:01:05,510 They're usually on the EDC slash AP 16 00:01:10,650 --> 00:01:16,740 and these are the two you are as are the two locations where you can go and find the packages that I 17 00:01:16,740 --> 00:01:18,240 want to install. 18 00:01:18,390 --> 00:01:22,210 You could actually master this using your web browser. 19 00:01:22,260 --> 00:01:24,500 Let's say I want to update my system. 20 00:01:25,180 --> 00:01:32,040 I can do that using the EPG get update. 21 00:01:32,210 --> 00:01:34,900 Now that will take once or just speed things up a bit. 22 00:01:39,480 --> 00:01:44,050 Now ever want to do a full distribution upgrades I can do that. 23 00:01:44,070 --> 00:01:46,140 Apt get upgrade. 24 00:01:52,160 --> 00:01:53,030 See all of that. 25 00:01:53,060 --> 00:02:00,320 These are all software packages that will be upgraded if I continue with these commands. 26 00:02:00,600 --> 00:02:05,870 Is poor exploitation of the compromise Linux host. 27 00:02:05,980 --> 00:02:12,010 Chances are that you won't get non-truth access and you want to find a vulnerability that will give 28 00:02:12,010 --> 00:02:13,900 you access. 29 00:02:13,900 --> 00:02:19,140 This usually involves finding and exploiting vulnerable software. 30 00:02:19,170 --> 00:02:25,860 You might also come across situations where the Linux box you broke into is not connected to the Internet. 31 00:02:25,890 --> 00:02:28,410 Let's say you're unethical engagement for. 32 00:02:28,500 --> 00:02:29,770 I don't know a bank. 33 00:02:29,940 --> 00:02:35,490 They invite you to come in and plug into their internal network as an employee and see if you can hack 34 00:02:35,490 --> 00:02:37,450 anything on that internal network. 35 00:02:37,980 --> 00:02:42,690 You managed to get into a Linux box and you find out that it's not the next to the Internet when you 36 00:02:42,690 --> 00:02:48,420 still want to use it as a stepping stone to try and get to other systems. 37 00:02:49,500 --> 00:02:54,250 To do that you need to install some packages on it but it's not connect to the Internet that's off line. 38 00:02:54,630 --> 00:02:58,770 So what do you do in this case for both situations. 39 00:02:58,950 --> 00:03:04,440 You could use the package commands and this is useful in multiple situations. 40 00:03:04,440 --> 00:03:10,680 Sometimes software cannot be found in depositories Nessus for example if you try to install it using 41 00:03:10,680 --> 00:03:14,660 the ABC get commands you will not be able to find it. 42 00:03:14,760 --> 00:03:20,460 You'll find that on the Nessus website and you'll notice that it ends with a thought that the the the 43 00:03:20,460 --> 00:03:28,530 extension which means that software for Linux Debian unlike FBD However we need to know that the package 44 00:03:28,530 --> 00:03:31,090 does not take care of the penances for us. 45 00:03:31,110 --> 00:03:36,930 So if a package needs and dependencies we'll have to take care of that ourselves to get back to the 46 00:03:36,930 --> 00:03:43,770 Xenogears that we've discussed in our both exploitation to find versions of installed applications and 47 00:03:43,770 --> 00:03:48,580 hope that you are going to want an all out dated vulnerable one. 48 00:03:48,750 --> 00:03:54,980 You can do that using the deep package minus and commands to install the package. 49 00:03:55,140 --> 00:03:57,330 Let's say I want to install Nessus for example. 50 00:03:57,330 --> 00:04:03,080 After downloading it I can do that using the package minus my commands. 51 00:04:03,470 --> 00:04:04,870 And to remove the baggage. 52 00:04:04,920 --> 00:04:09,320 You can do that using the package minus commands. 53 00:04:09,360 --> 00:04:13,280 Now you might be wondering what I just said that the Linux system was off line. 54 00:04:13,320 --> 00:04:18,580 And how am I saying that I can install Nessus after downloading it. 55 00:04:19,110 --> 00:04:24,720 That's going to be for another chapter in another chapter we're going to be learning how to download 56 00:04:24,810 --> 00:04:26,980 stuff on our Candy machine. 57 00:04:27,390 --> 00:04:34,890 And then how we can use our Gadi machine as a server to upload stuff from our galley to the victim machine. 58 00:04:35,510 --> 00:04:41,370 Now let's not worry too much about it let's just assume that you somehow managed to get the Nessus package 59 00:04:41,400 --> 00:04:42,740 on the victim machine. 60 00:04:43,020 --> 00:04:48,240 And you can use that package command to install and remove it. 61 00:04:48,240 --> 00:04:52,470 Now remember these are all situations that happen in ethical hacking engagements. 62 00:04:52,470 --> 00:04:57,330 Having said that and I think that having an agent you want to make sure that you have the permission 63 00:04:57,570 --> 00:05:02,330 to install and remove softer off your clothing on the machine. 64 00:05:02,670 --> 00:05:11,280 So mission for the section on your Gadi machine install files ilah on your Windows machine activate 65 00:05:11,360 --> 00:05:12,370 FTB. 66 00:05:12,450 --> 00:05:13,850 If you don't know how to do that. 67 00:05:13,890 --> 00:05:19,050 We explain that in our hacking for beginners course go there and he knew that section on hacking for 68 00:05:19,050 --> 00:05:24,590 beginners and using structures on those videos activate FTB on your Windows machine. 69 00:05:24,870 --> 00:05:31,180 Then from an open file Zilah and next year is over on Windows. 70 00:05:31,190 --> 00:05:34,650 So I had to upload and download some files. 71 00:05:34,860 --> 00:05:40,400 Then on your candy machine download and install Nessus. 72 00:05:40,620 --> 00:05:43,430 Once you're done we can move onto the next section. 7794
