1 00:00:03,210 --> 00:00:09,390 Now we have all of our virtual machines set up and connected to a private network. 2 00:00:09,660 --> 00:00:16,260 We want to see how to setup a public network so that every now and then we'll want to change our computers 3 00:00:16,260 --> 00:00:21,540 over to a public network so that they can see out to the Internet, for example, in the social engineering 4 00:00:21,570 --> 00:00:22,170 exercise. 5 00:00:22,170 --> 00:00:22,740 That's coming up. 6 00:00:23,100 --> 00:00:29,760 We're going to see how to connect out and copy the Twitter or Facebook or another Web sites log in page 7 00:00:30,120 --> 00:00:34,950 that we can use in a phishing email to train people how to spot phishing emails. 8 00:00:34,950 --> 00:00:35,610 Much better. 9 00:00:35,970 --> 00:00:39,020 So we're going to come to the virtual box. 10 00:00:40,210 --> 00:00:46,360 And come down to preferences on a Windows P.S. this is going to be under file preferences and the file 11 00:00:46,360 --> 00:00:46,870 menu. 12 00:00:48,670 --> 00:00:52,240 And this is where we're going to set up our new public nat network. 13 00:00:52,960 --> 00:00:58,870 So we said in the PowerPoint presentation a little earlier that this would be a 10 Daddo dot nine network 14 00:00:58,870 --> 00:00:59,380 address. 15 00:00:59,710 --> 00:01:04,360 So we're gonna add a new NAT network and a NAT network network address. 16 00:01:04,360 --> 00:01:09,490 Translation will let us use the our host computers Internet connection to get out to the Internet instead 17 00:01:09,490 --> 00:01:13,960 of a host only where we can only see from one machine to the other, we're gonna be able to see Google 18 00:01:14,230 --> 00:01:19,960 and see Facebook and Twitter will be able to connect out and pull exercises from Web site, for example. 19 00:01:20,350 --> 00:01:26,080 So we can go to our network under files, preferences or under virtual box preferences. 20 00:01:26,590 --> 00:01:31,200 And we come to a network and that network we're gonna create a new net network. 21 00:01:31,600 --> 00:01:33,040 And let's change the settings. 22 00:01:33,390 --> 00:01:37,930 I'm, first of all, going to call this public nat'l so that it'll be easy to find. 23 00:01:38,140 --> 00:01:42,980 And it'll help me remember that when I'm connected to this network, I'm going to be public. 24 00:01:43,000 --> 00:01:45,670 I'm going to have a view out to the Internet. 25 00:01:46,150 --> 00:01:52,810 I want to change the network, address the cider, or this is just another way of specifying a network 26 00:01:52,810 --> 00:01:58,050 mask when it's at the 10 DataDot nine address for this public network. 27 00:01:58,060 --> 00:02:01,820 We use Tendo three for our private network so we can tell those apart. 28 00:02:02,950 --> 00:02:05,020 And then I've got a 24 bit mask. 29 00:02:05,050 --> 00:02:11,890 That just means the first eight plus eight plus eight or 24 bits or the first three bytes of this network 30 00:02:11,890 --> 00:02:12,790 will stay the same. 31 00:02:13,180 --> 00:02:23,020 So tendo dot nine thato slash twenty four is the same as a tendo dot nine go with a 255 255 255 zero 32 00:02:23,260 --> 00:02:26,290 mask and we are going to support d.H C.p. 33 00:02:26,560 --> 00:02:28,630 And we do that all in one quick screen here. 34 00:02:29,860 --> 00:02:30,580 Very good. 35 00:02:31,060 --> 00:02:32,470 And we'll see public, Matt. 36 00:02:32,510 --> 00:02:35,770 And don't worry about the part that says renamed from that network. 37 00:02:36,920 --> 00:02:41,780 Now that we've created that network, we need to set it up on our Caleigh and Windows machines will 38 00:02:41,780 --> 00:02:46,790 just do it on these two Maximova good and cinnabar Android device so that can see out of the Internet 39 00:02:47,200 --> 00:02:47,850 a split-Level. 40 00:02:47,870 --> 00:02:51,890 We're almost always going to keep on that private hosted only network. 41 00:02:52,190 --> 00:02:57,080 But when we do our social engineering exercise, we need to be able to see out from Kalli to Microsoft 42 00:02:57,080 --> 00:02:57,590 Windows. 43 00:02:59,030 --> 00:03:01,580 And then we might want to go out to the Internet and copy a site. 44 00:03:02,000 --> 00:03:04,410 So we're going to say Caleigh network. 45 00:03:05,030 --> 00:03:08,860 We're going to change from that host only adapter to a map network. 46 00:03:08,870 --> 00:03:10,130 And here's the tough part. 47 00:03:10,280 --> 00:03:16,280 There's also the private, completely hidden net where you can't see another machine. 48 00:03:17,300 --> 00:03:21,610 You can't use the our host computers network connection out to the Internet. 49 00:03:22,070 --> 00:03:23,530 But we never want to use in that. 50 00:03:23,540 --> 00:03:26,610 We want to use that network when we're looking for our public. 51 00:03:26,630 --> 00:03:26,910 Matt. 52 00:03:27,050 --> 00:03:30,240 And you see, that did come up as our option for the public. 53 00:03:30,270 --> 00:03:30,770 Matt. 54 00:03:32,580 --> 00:03:32,880 Go. 55 00:03:33,720 --> 00:03:36,000 And then back on our Caleigh box, once you restart it. 56 00:03:36,330 --> 00:03:45,000 You can either just do the disconnect the network adapter and reconnect, then try and I p a. 57 00:03:46,480 --> 00:03:52,540 And you notice we did get a 10 dot oh address on our ten out of the Nine Network. 58 00:03:52,870 --> 00:03:59,690 So 10 out of the nine dot seven this time on Kelly Linux, it'll change because it is d.H S.P. Dynamic 59 00:03:59,710 --> 00:04:01,210 Host Control Protocol. 60 00:04:01,720 --> 00:04:04,270 So it's alright if it's a different network from time to time. 61 00:04:04,280 --> 00:04:07,360 We just need to know what our IP address is tonight. 62 00:04:07,370 --> 00:04:07,540 Odah. 63 00:04:07,650 --> 00:04:10,060 Ninety seven means we're on the public net network. 64 00:04:10,570 --> 00:04:18,940 That means that we could ping out to w w w dot Google dot com for example, and we can see the real 65 00:04:18,940 --> 00:04:19,450 Google. 66 00:04:19,840 --> 00:04:22,510 And we'll have to use the control C to stop the pain. 67 00:04:23,110 --> 00:04:24,340 And Kelly Linux. 68 00:04:24,730 --> 00:04:25,420 Not bad. 69 00:04:25,870 --> 00:04:29,090 So our Caleigh machine is on the Tendo DOT nine Seven Network. 70 00:04:29,110 --> 00:04:32,260 We can do the same thing for our Windows box. 71 00:04:32,740 --> 00:04:33,820 If I come to the network. 72 00:04:35,530 --> 00:04:38,690 And change that network setting, not Matt, but Matt. 73 00:04:38,740 --> 00:04:39,490 Network. 74 00:04:39,910 --> 00:04:41,760 We'll find the public Matt Press. 75 00:04:41,870 --> 00:04:42,270 OK. 76 00:04:43,840 --> 00:04:46,700 And we can go out and do the same thing for the Android device. 77 00:04:46,730 --> 00:04:49,220 It'll need to see up to the network every now and then as well. 78 00:04:49,310 --> 00:04:52,360 When we use it now, network, public, not press. 79 00:04:52,400 --> 00:04:52,790 OK. 80 00:04:55,250 --> 00:04:59,980 And our Windows device will restart it now if we saved our settings last time. 81 00:05:00,000 --> 00:05:04,740 We may need to use our ability to restart the windows networking. 82 00:05:05,160 --> 00:05:06,810 So I'll show how to do that one more time. 83 00:05:08,390 --> 00:05:14,810 So I'm booted into my Windows computer and I can see that I saved my settings last time, so I may not. 84 00:05:15,110 --> 00:05:16,670 I didn't do a full reboot. 85 00:05:16,700 --> 00:05:20,270 You can always reboot your computer to get a new IP address. 86 00:05:20,990 --> 00:05:23,690 But we can check it just by looking down here. 87 00:05:23,780 --> 00:05:30,110 In fact, if I just hover over this, I'll see that I am connected on Tendo DOT nine nine. 88 00:05:30,530 --> 00:05:31,160 That's good to know. 89 00:05:31,190 --> 00:05:36,980 But if you ever need to, you can disconnect the network, reconnect the network adapter, run your 90 00:05:36,980 --> 00:05:38,020 IP config. 91 00:05:40,550 --> 00:05:40,910 Good. 92 00:05:40,940 --> 00:05:42,470 We got a turned at nine nine. 93 00:05:42,560 --> 00:05:43,730 But remember our command. 94 00:05:47,920 --> 00:05:53,100 To change it, to reset the windows, networking is in an administrator command prompt that CMB. 95 00:05:53,650 --> 00:05:53,950 Right. 96 00:05:53,960 --> 00:05:59,860 And then click on Run as administrator NHTSA to Windsock Reset and then IP config. 97 00:06:01,490 --> 00:06:03,020 Tonight at 9:00 dot nine. 98 00:06:03,470 --> 00:06:08,120 So now our windows and our Caleigh machines are on the same public network. 99 00:06:08,150 --> 00:06:09,530 I could ping Google from here. 100 00:06:09,890 --> 00:06:12,320 I'm going to make just one other change on my Windows computer. 101 00:06:12,350 --> 00:06:19,850 I'm going to come to the properties for our command prompt windows, and I'm going to change it up just 102 00:06:19,850 --> 00:06:20,420 a little bit. 103 00:06:20,480 --> 00:06:25,550 I'm going to make the screen text a good bright hackery green. 104 00:06:26,630 --> 00:06:32,870 And will change the fight and make that bigger so that you'll be able to read things better. 105 00:06:33,960 --> 00:06:36,020 Maybe 24 Bould, OK? 106 00:06:37,140 --> 00:06:38,130 Very nice. 107 00:06:39,210 --> 00:06:39,550 All right. 108 00:06:39,600 --> 00:06:46,260 So we have all of our machines set up and networking into each other so I can see my Caleigh machine 109 00:06:46,260 --> 00:06:46,740 from here. 110 00:06:46,740 --> 00:06:50,490 I can check that by paying 10 out Odah nine seven. 111 00:06:53,110 --> 00:06:56,980 Or enter here, whatever you got for your Caleigh machines address. 112 00:06:57,340 --> 00:07:02,050 I set up tons of computers all the time so I may have different addresses from you, but mine was 10 113 00:07:02,050 --> 00:07:03,400 dot dot ninety seven. 114 00:07:04,060 --> 00:07:05,770 And I'll ping that from windows. 115 00:07:06,850 --> 00:07:12,130 And you'll notice if you try to ping your Windows computer from Kalli, you're actually not going to 116 00:07:12,130 --> 00:07:12,840 be able to see it. 117 00:07:12,880 --> 00:07:14,770 And that's because the Windows firewall. 118 00:07:15,040 --> 00:07:20,680 But we'll see how to fix that and how to get around it when we get into the lessons on hacking windows. 119 00:07:21,000 --> 00:07:25,180 But right now, you've got a fully configured network and it's time to actually do some hacking. 120 00:07:25,210 --> 00:07:31,060 So in the next section, we're going to see how to do a social engineering attack, a phishing attack 121 00:07:31,390 --> 00:07:35,200 from Caleigh into Windows, just like we'd see out on the real Internet. 122 00:07:35,530 --> 00:07:36,610 We'll see you in the next section.
