1
00:00:00,320 --> 00:00:07,820
So far we have seen how can we use Haveibeenpwned, Dhash and intelligence to access data from leaked

2
00:00:07,820 --> 00:00:09,350
or breached databases?

3
00:00:09,470 --> 00:00:15,890
In this lecture, I would like to show you how can you set up your virtual machine to download leak

4
00:00:15,890 --> 00:00:22,910
databases on your virtual machine so you don't have to have a subscription to access leaked databases?

5
00:00:23,180 --> 00:00:29,300
To safely download and search through leaked databases, you need to create a virtual machine.

6
00:00:29,300 --> 00:00:32,420
Now the question is what is a virtual machine?

7
00:00:33,140 --> 00:00:39,920
A virtual machine is basically a software emulation of a physical computer, which allows you to run

8
00:00:39,920 --> 00:00:45,350
multiple operating systems at the same time on a single physical computer.

9
00:00:46,040 --> 00:00:52,400
So, for example, imagine you have a powerful computer and you want to run two different operating

10
00:00:52,400 --> 00:00:53,510
system on it.

11
00:00:53,720 --> 00:01:00,620
Instead of partitioning your hard drive and installing each operating system directly onto it, you

12
00:01:00,620 --> 00:01:09,810
can use virtualization Software like VMware, VirtualBox or Hyper-V to create a virtual machine, and

13
00:01:09,810 --> 00:01:18,420
the virtual machine will always share the resources of the host machine, such as the CPU, memory and

14
00:01:18,420 --> 00:01:27,180
storage, and it will allow you to install and run different operating system software and applications

15
00:01:27,180 --> 00:01:32,580
on these virtual machines, just like you would do on a physical computer.

16
00:01:32,580 --> 00:01:38,130
If you do not have the resources to create a virtual machine, then you might want to use a different

17
00:01:38,130 --> 00:01:40,980
browser for your Osint investigation.

18
00:01:41,610 --> 00:01:46,440
Now, why it's so important to use a virtual machine for Osint investigations?

19
00:01:46,680 --> 00:01:52,350
There are four main reasons to use a virtual machine, and the first one is security.

20
00:01:52,500 --> 00:02:00,240
Because Osint often involves gathering information from various sources on the internet, and some of

21
00:02:00,240 --> 00:02:08,340
which may not be trustworthy, so using a virtual machine allows you to isolate potentially malicious

22
00:02:08,340 --> 00:02:11,940
content or sources from your main operating system.

23
00:02:12,780 --> 00:02:19,560
So if your virtual machine got hacked or infected with a malware, you can easily discard the virtual

24
00:02:19,560 --> 00:02:22,500
machine without affecting your main operating system.

25
00:02:23,070 --> 00:02:30,450
The second important reason is for anonymity, because virtual machines can be configured to use tools

26
00:02:30,450 --> 00:02:38,670
such as VPNs or Tor to enhance anonymity when conducting Osint investigations, and by running Osint

27
00:02:38,670 --> 00:02:45,720
tools and accessing online resources within virtual Machine, you can minimize the risk of exposing

28
00:02:45,720 --> 00:02:50,370
your real IP address or compromising your identity.

29
00:02:51,000 --> 00:02:58,650
In addition to that, virtual machines provide isolated environment where you can safely execute potentially

30
00:02:58,650 --> 00:03:03,960
risky operations, such as visiting suspicious websites or opening unknown files.

31
00:03:03,960 --> 00:03:08,790
And since there is a chance that a leaked league database might contain a malicious file.

32
00:03:08,790 --> 00:03:15,060
We will use a virtual machine to download these databases instead of using our main machine.

33
00:03:15,060 --> 00:03:22,800
So if any malicious activity occurs within the virtual machine, it is contained and does not affect

34
00:03:22,800 --> 00:03:24,480
your main operating system.

35
00:03:25,110 --> 00:03:32,850
And lastly, virtual machine provides you with an operating system flexibility because sometimes different

36
00:03:32,880 --> 00:03:40,020
Osint tools may require specific operating system, which is something that we will see in future lectures.

37
00:03:40,020 --> 00:03:46,080
You might need to use Linux to use some awesome tools that may automate your work.

38
00:03:46,350 --> 00:03:51,660
So virtual machines allow you to quickly set up and switch between different operating systems without

39
00:03:51,660 --> 00:03:54,840
the need for multiple physical computers.

40
00:03:56,250 --> 00:04:01,320
So to install windows as a virtual machine, first of all, you want to go to the link that you will

41
00:04:01,320 --> 00:04:03,690
find in the resources of this lecture.

42
00:04:03,690 --> 00:04:10,090
And then you want to click on Windows Host to install VirtualBox on your windows operating system.

43
00:04:10,120 --> 00:04:15,310
Of course, if you are using Mac or Linux, then you can download and install the version that works

44
00:04:15,310 --> 00:04:17,050
with your operating system.

45
00:04:17,050 --> 00:04:21,370
In my case, I've already downloaded VirtualBox on my computer.

46
00:04:21,940 --> 00:04:27,700
Now, to install windows on VirtualBox, we need an ISO file, which we can download from the official

47
00:04:27,700 --> 00:04:29,380
page from Microsoft.

48
00:04:29,380 --> 00:04:33,100
So you want to go to the link that you will find in the resources of this lecture.

49
00:04:33,100 --> 00:04:39,370
And then you scroll down a little bit and then select Windows 11 and click on Download now after this

50
00:04:39,400 --> 00:04:40,900
you want to select your region.

51
00:04:40,900 --> 00:04:43,180
In my case I'm going to say German.

52
00:04:43,630 --> 00:04:46,090
And then I'm going to click on confirm.

53
00:04:46,570 --> 00:04:50,890
After downloading VirtualBox installer and Windows ISO image.

54
00:04:50,890 --> 00:04:53,740
First of all we are going to install VirtualBox.

55
00:04:53,740 --> 00:04:56,680
In my case I've already installed it on my machine.

56
00:04:56,680 --> 00:04:58,210
So I'm going to run it.

57
00:04:58,210 --> 00:05:03,130
And then I'm going to click on new and I'm going to call it Windows 11.

58
00:05:03,790 --> 00:05:07,870
And then I'll select the ISO image that I have downloaded right here.

59
00:05:07,870 --> 00:05:13,010
And then I'm going to click on Skip unattended installation and click on next.

60
00:05:13,010 --> 00:05:17,510
And for this virtual machine we need at least four gigabytes of Ram.

61
00:05:17,510 --> 00:05:19,610
And then I'm going to click on next.

62
00:05:19,610 --> 00:05:22,490
And then next and finish.

63
00:05:23,090 --> 00:05:28,070
And then we are going to start the virtual machine that we have created by clicking on start.

64
00:05:29,510 --> 00:05:32,120
And then we need to hit enter.

65
00:05:33,860 --> 00:05:39,110
And here we can select the language I'm going to keep everything like this and click on next.

66
00:05:39,770 --> 00:05:41,120
And then next.

67
00:05:41,120 --> 00:05:44,750
And then I'm going to agree and click on next.

68
00:05:44,750 --> 00:05:47,780
And then click on I don't have a product key.

69
00:05:47,780 --> 00:05:51,020
And then I have to select the image that I would like to install.

70
00:05:51,020 --> 00:05:53,960
In my case I'm going to click on Windows 11 Pro.

71
00:05:53,960 --> 00:05:57,740
And then next accept and then install.

72
00:05:58,010 --> 00:06:03,230
Now before we continue, I'm going to disable the internet so that we don't download any updates for

73
00:06:03,230 --> 00:06:03,590
now.

74
00:06:03,590 --> 00:06:06,800
So you want to click right here and then choose Not Attached.

75
00:06:06,800 --> 00:06:08,300
And then click on okay.

76
00:06:08,300 --> 00:06:12,170
And then you want to choose your region and the keyboard layout.

77
00:06:12,910 --> 00:06:14,470
And then I'm going to say Skip.

78
00:06:14,470 --> 00:06:17,410
And then I'm going to click on I don't have internet.

79
00:06:17,410 --> 00:06:19,780
And then I'm going to choose a name.

80
00:06:19,780 --> 00:06:21,370
So it's going to be anything.

81
00:06:21,400 --> 00:06:23,080
It could be test for example.

82
00:06:23,110 --> 00:06:25,600
And then I'm not going to enter a password.

83
00:06:25,600 --> 00:06:29,020
You can enter a password if you would like to and then hit enter.

84
00:06:29,020 --> 00:06:31,240
And then I'm going to select or no.

85
00:06:34,690 --> 00:06:37,330
And now our virtual machine is ready.

86
00:06:37,330 --> 00:06:43,450
The last thing I'm going to be doing is to install VirtualBox Guest tools, which will allow me to copy

87
00:06:43,450 --> 00:06:49,660
and paste from my host machine to my VirtualBox, and will allow me to create a file sharing between

88
00:06:49,660 --> 00:06:53,590
my host machine and the virtual machine, and much more.

89
00:06:53,590 --> 00:07:00,880
So to do this, I'm going to click on device and then click on Insert Guest Additions CD image.

90
00:07:01,510 --> 00:07:04,690
And then I'm going to open the File Explorer.

91
00:07:05,050 --> 00:07:10,240
And I'm going to click on this and then run this tool.

92
00:07:10,420 --> 00:07:14,660
So I'm going to click on next next Install.

93
00:07:17,000 --> 00:07:18,980
And then I'm going to click on reboot.

94
00:07:19,010 --> 00:07:19,670
Now.

95
00:07:22,790 --> 00:07:29,330
After installing VirtualBox guest additions I'm going to be enabling the copy and paste on the virtual

96
00:07:29,330 --> 00:07:29,810
machine.

97
00:07:29,810 --> 00:07:34,010
So I'm going to click on devices and then drag and drop.

98
00:07:34,010 --> 00:07:36,830
And I'm going to make it bidirectional.

99
00:07:36,830 --> 00:07:42,200
And I'm also going to click on Shared Clipboard and click on bidirectional.

100
00:07:42,680 --> 00:07:50,180
And if I would like to I can also create a shared folder between my virtual machine and my host machine.

101
00:07:50,180 --> 00:07:55,370
Now if you would like to change the resolution of the virtual machine, you can do this.

102
00:07:55,370 --> 00:07:58,640
So I'm going to click on view and then full screen mode.

103
00:07:58,640 --> 00:08:04,190
And you can see that now we have our virtual machine in full resolution.

104
00:08:04,730 --> 00:08:10,460
So in this lecture we have learned what a virtual machine is and why do we need to use a virtual machine

105
00:08:10,460 --> 00:08:12,650
to conduct Osint investigations.

106
00:08:12,650 --> 00:08:16,670
And how we can set up our Osint virtual machine.
