Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:00,170 --> 00:00:02,190
The first operating system
2
00:00:02,190 --> 00:00:07,190
that we're going to install in our lab is Kali Linux.
3
00:00:07,550 --> 00:00:09,170
See, throughout the course,
4
00:00:09,170 --> 00:00:12,780
we're going to use a number of hacking tools.
5
00:00:12,780 --> 00:00:15,295
You can install each of these tools manually,
6
00:00:15,295 --> 00:00:19,810
or you can do what most hackers do, including myself,
7
00:00:19,810 --> 00:00:21,490
and save time and effort
8
00:00:21,490 --> 00:00:25,023
and use an operating system designed for hacking.
9
00:00:25,910 --> 00:00:29,550
We're going to use an operating system called Kali Linux.
10
00:00:29,550 --> 00:00:32,550
It's a Linux distro based on Debian,
11
00:00:32,550 --> 00:00:34,870
and the only difference between Kali
12
00:00:34,870 --> 00:00:38,310
and the actual original Debian Linux distro
13
00:00:38,310 --> 00:00:41,660
is the fact that Kali has a lot of hacking
14
00:00:41,660 --> 00:00:43,760
and penetration testing tools,
15
00:00:43,760 --> 00:00:46,870
pre-installed and pre-configured in it.
16
00:00:46,870 --> 00:00:49,270
Therefore, once you install Kali,
17
00:00:49,270 --> 00:00:52,550
you will have access to so many hacking tools
18
00:00:52,550 --> 00:00:55,930
without the need to install or configure any of them,
19
00:00:55,930 --> 00:00:59,720
which will save you a lot of time, and a lot of effort.
20
00:00:59,720 --> 00:01:02,060
Now just like any other operating system,
21
00:01:02,060 --> 00:01:04,320
you can install it as a main machine
22
00:01:04,320 --> 00:01:07,130
or as a virtual machine.
23
00:01:07,130 --> 00:01:09,990
Now I'm going to install it as a virtual machine,
24
00:01:09,990 --> 00:01:13,060
because like I explained in the previous lecture,
25
00:01:13,060 --> 00:01:15,290
we will not lose any functionality
26
00:01:15,290 --> 00:01:18,520
by using operating systems as virtual machines.
27
00:01:18,520 --> 00:01:20,760
And it comes with a lot of benefits
28
00:01:20,760 --> 00:01:24,010
because it's completely isolated from our computer
29
00:01:24,010 --> 00:01:25,280
that we always use,
30
00:01:25,280 --> 00:01:27,160
So if we break the virtual machine
31
00:01:27,160 --> 00:01:29,490
or if we want to delete it and reset it,
32
00:01:29,490 --> 00:01:32,593
it will not affect our main operating system.
33
00:01:33,720 --> 00:01:35,300
Now the first thing that you want to do
34
00:01:35,300 --> 00:01:38,280
is download the virtual image of Kali Linux,
35
00:01:38,280 --> 00:01:39,300
so you can download it
36
00:01:39,300 --> 00:01:42,090
from the resources of this lecture,
37
00:01:42,090 --> 00:01:44,960
to access the resources of the current lecture,
38
00:01:44,960 --> 00:01:47,450
we're gonna scroll down to the lecture,
39
00:01:47,450 --> 00:01:50,490
we're gonna click on the resources icon,
40
00:01:50,490 --> 00:01:53,383
and then we're gonna click on the resource that we want.
41
00:01:55,690 --> 00:01:58,150
Now before going ahead with this,
42
00:01:58,150 --> 00:02:00,000
I want to highlight something
43
00:02:00,000 --> 00:02:02,670
that is very, very, very important.
44
00:02:02,670 --> 00:02:04,530
So please pay attention.
45
00:02:04,530 --> 00:02:09,530
This is a custom Kali image that I made for my courses.
46
00:02:09,810 --> 00:02:13,070
It is smoother and faster than the original one,
47
00:02:13,070 --> 00:02:15,430
it fixes a number of bugs
48
00:02:15,430 --> 00:02:18,870
and it contains a number of extra programs
49
00:02:18,870 --> 00:02:20,700
that we need for this course
50
00:02:20,700 --> 00:02:24,283
and are not included in the original release.
51
00:02:25,210 --> 00:02:28,360
You do not have to use this custom image.
52
00:02:28,360 --> 00:02:30,770
You can use the original one.
53
00:02:30,770 --> 00:02:34,620
You can even use just a normal Linux distribution,
54
00:02:34,620 --> 00:02:38,200
as long as you know how to manually install
55
00:02:38,200 --> 00:02:39,890
all of the missing programs
56
00:02:39,890 --> 00:02:43,300
and apply the fixes that I did myself.
57
00:02:43,300 --> 00:02:46,663
And you can see a full list of them here on the left.
58
00:02:48,230 --> 00:02:52,200
Therefore, if you ask us a question in the Q and A section,
59
00:02:52,200 --> 00:02:54,450
and you're not using the custom image,
60
00:02:54,450 --> 00:02:56,510
the first thing that we will ask you
61
00:02:56,510 --> 00:03:00,410
is to use the custom Kali image that we made for you,
62
00:03:00,410 --> 00:03:03,450
because we know the original one is broken
63
00:03:03,450 --> 00:03:06,290
and we will not know the changes you made,
64
00:03:06,290 --> 00:03:08,450
in order to fix it.
65
00:03:08,450 --> 00:03:11,070
So if you have a 64 bit computer,
66
00:03:11,070 --> 00:03:13,630
download it from one of these links,
67
00:03:13,630 --> 00:03:16,330
or if you have a 32 bit computer,
68
00:03:16,330 --> 00:03:19,573
then download the 32 bits version from here.
69
00:03:20,520 --> 00:03:22,060
While waiting on the download,
70
00:03:22,060 --> 00:03:24,980
check out our VIP community right here,
71
00:03:24,980 --> 00:03:26,730
and our YouTube channel.
72
00:03:26,730 --> 00:03:29,876
We actually post hacking content on it regularly.
73
00:03:29,876 --> 00:03:32,530
So you'll probably find this very, very useful.
74
00:03:32,530 --> 00:03:34,980
So make sure you subscribe to stay updated
75
00:03:34,980 --> 00:03:37,423
with the latest stuff that we post in here.
76
00:03:38,860 --> 00:03:40,910
Once the download is complete,
77
00:03:40,910 --> 00:03:45,330
you'll be ready to install Kali as a virtual machine.
78
00:03:45,330 --> 00:03:48,310
I will walk you through that in the next lectures,
79
00:03:48,310 --> 00:03:49,930
but before moving on,
80
00:03:49,930 --> 00:03:54,730
we need to enable virtualization to run virtual machines.
81
00:03:54,730 --> 00:03:56,340
You only need to do that,
82
00:03:56,340 --> 00:03:58,760
if you're running Windows or Linux,
83
00:03:58,760 --> 00:04:00,600
you do not need to do this,
84
00:04:00,600 --> 00:04:04,950
if you're running Apple macOs as Apple computers come
85
00:04:04,950 --> 00:04:08,300
with virtualization enabled by default.
86
00:04:08,300 --> 00:04:10,300
So skip the rest of this lecture,
87
00:04:10,300 --> 00:04:12,820
if you're using an Apple computer.
88
00:04:12,820 --> 00:04:14,940
If you're using windows or Linux,
89
00:04:14,940 --> 00:04:18,540
then continue with me to see how to enable it.
90
00:04:18,540 --> 00:04:21,020
So on windows before enabling it,
91
00:04:21,020 --> 00:04:23,940
if you want to check if it is already enabled,
92
00:04:23,940 --> 00:04:26,083
you're gonna have to go to the start menu.
93
00:04:26,980 --> 00:04:28,883
We're gonna look for the task manager,
94
00:04:30,560 --> 00:04:35,560
I have it right here, I'm gonna click on more details,
95
00:04:35,940 --> 00:04:38,410
I'm gonna go on performance,
96
00:04:38,410 --> 00:04:42,500
And if you look in here beside virtualization,
97
00:04:42,500 --> 00:04:45,760
you can see in my case, it's saying disabled.
98
00:04:45,760 --> 00:04:47,810
So we're gonna have to enable it.
99
00:04:47,810 --> 00:04:50,420
But if it's saying enabled for you,
100
00:04:50,420 --> 00:04:52,410
then you can skip the rest of this lecture
101
00:04:52,410 --> 00:04:54,360
and move on to the next lecture.
102
00:04:54,360 --> 00:04:55,810
If it's saying disabled,
103
00:04:55,810 --> 00:04:57,510
then continue with this lecture,
104
00:04:57,510 --> 00:05:01,720
to learn how to enable virtualization.
105
00:05:01,720 --> 00:05:03,070
So to do that,
106
00:05:03,070 --> 00:05:06,100
we're gonna have to first restart the computer
107
00:05:06,100 --> 00:05:09,150
and as it's booting, as it's starting,
108
00:05:09,150 --> 00:05:11,910
you're gonna have to price a key combination.
109
00:05:11,910 --> 00:05:15,060
Usually one of the F keys from your keyboard
110
00:05:15,060 --> 00:05:16,880
to enter the bio settings,
111
00:05:16,880 --> 00:05:19,000
and from there, we can enable it.
112
00:05:19,000 --> 00:05:20,830
So let me show you how to do it.
113
00:05:20,830 --> 00:05:22,820
Keep in mind you only need to do this
114
00:05:22,820 --> 00:05:25,410
If virtualization is disabled.
115
00:05:25,410 --> 00:05:28,080
If it's enabled, then you can simply skip this
116
00:05:28,080 --> 00:05:30,393
and continue with the rest of the course.
117
00:05:31,340 --> 00:05:33,260
Entering the BIOS settings varies
118
00:05:33,260 --> 00:05:35,430
depending on the computer that you have,
119
00:05:35,430 --> 00:05:37,200
and depending on the motherboard.
120
00:05:37,200 --> 00:05:38,040
On the right here,
121
00:05:38,040 --> 00:05:41,460
I have a table of the most common computers,
122
00:05:41,460 --> 00:05:44,010
along with the buttons that you need to press
123
00:05:44,010 --> 00:05:46,770
in order to enter the bias settings.
124
00:05:46,770 --> 00:05:50,330
So as soon as you turn on the computer or restart it,
125
00:05:50,330 --> 00:05:52,600
you'll need to press the button
126
00:05:52,600 --> 00:05:54,710
relevant to your computer in here
127
00:05:54,710 --> 00:05:57,600
in order to enter the BIOS settings.
128
00:05:57,600 --> 00:05:58,710
Once you're there,
129
00:05:58,710 --> 00:06:01,580
you want to make sure you enable virtualization.
130
00:06:01,580 --> 00:06:04,963
So let me show you how to do this on a real computer.
131
00:06:05,950 --> 00:06:08,240
This is a Lenovo computer.
132
00:06:08,240 --> 00:06:11,330
Therefore, based on the table that I just showed you,
133
00:06:11,330 --> 00:06:15,960
I will need to press F2 as soon as I turn on this computer,
134
00:06:15,960 --> 00:06:18,803
in order to enter into its BIOS settings.
135
00:06:19,640 --> 00:06:22,860
So first I'm gonna hit the power button to turn it on,
136
00:06:22,860 --> 00:06:24,740
and as it's being turned on
137
00:06:24,740 --> 00:06:27,483
I'm gonna keep pressing F2 to enter the settings.
138
00:06:29,220 --> 00:06:30,680
On perfect, as you can see,
139
00:06:30,680 --> 00:06:33,280
I am in the bios settings right now.
140
00:06:33,280 --> 00:06:36,310
Now keep in mind, depending on your computer,
141
00:06:36,310 --> 00:06:40,320
the settings might look different than what I have in here.
142
00:06:40,320 --> 00:06:42,280
The main thing you need to keep in mind,
143
00:06:42,280 --> 00:06:44,793
is to enable virtualization.
144
00:06:45,660 --> 00:06:47,940
This option can be found in a different window
145
00:06:47,940 --> 00:06:50,080
and any of these windows or tabs.
146
00:06:50,080 --> 00:06:51,890
But the main thing you want to keep in mind,
147
00:06:51,890 --> 00:06:56,890
is to look for an option called virtualization, VT-x, AMD-V,
148
00:06:57,120 --> 00:07:00,980
or any of the options in here and enable it.
149
00:07:00,980 --> 00:07:02,290
So, as you can see for me,
150
00:07:02,290 --> 00:07:05,910
the first window that I see is just an information window.
151
00:07:05,910 --> 00:07:09,130
It doesn't really allow me to modify anything.
152
00:07:09,130 --> 00:07:11,170
Now you can use the keyboard to navigate
153
00:07:11,170 --> 00:07:13,520
between these windows or these tabs.
154
00:07:13,520 --> 00:07:15,650
So I'm gonna press the right arrow
155
00:07:15,650 --> 00:07:18,500
to go to the configuration window.
156
00:07:18,500 --> 00:07:19,430
And in here,
157
00:07:19,430 --> 00:07:21,550
the only thing that I want to modify,
158
00:07:21,550 --> 00:07:24,880
is Intel virtualization technology.
159
00:07:24,880 --> 00:07:29,020
So I'm gonna use the down arrow to navigate to that,
160
00:07:29,020 --> 00:07:31,510
and I'm gonna hit enter to change the setting,
161
00:07:31,510 --> 00:07:34,720
press down to set it to enabled and hit enter again,
162
00:07:34,720 --> 00:07:36,090
to select it.
163
00:07:36,090 --> 00:07:38,690
Now if you're not sure about how to use this interface,
164
00:07:38,690 --> 00:07:39,650
because like I said,
165
00:07:39,650 --> 00:07:42,410
you might actually get a different interface,
166
00:07:42,410 --> 00:07:45,540
keep an eye on the instructions that you see at the bottom,
167
00:07:45,540 --> 00:07:47,930
as they tell you exactly how to navigate
168
00:07:47,930 --> 00:07:50,220
and modify the settings.
169
00:07:50,220 --> 00:07:52,400
Now I'm done with the configuration window.
170
00:07:52,400 --> 00:07:54,560
I'm gonna press the right arrow again,
171
00:07:54,560 --> 00:07:56,670
to go into the security tab.
172
00:07:56,670 --> 00:07:58,000
We're gonna go to the exit,
173
00:07:58,000 --> 00:08:01,580
so again, I'm gonna press the right arrow again,
174
00:08:01,580 --> 00:08:03,600
and I'm gonna select the first option,
175
00:08:03,600 --> 00:08:06,200
exit saving settings.
176
00:08:06,200 --> 00:08:08,290
It's gonna ask me, do I really want to do this?
177
00:08:08,290 --> 00:08:10,050
I'm gonna say yes,
178
00:08:10,050 --> 00:08:13,490
the computer will restart with virtualization enabled.
179
00:08:13,490 --> 00:08:15,110
So in the next lectures,
180
00:08:15,110 --> 00:08:17,650
when we get to installing virtual machines,
181
00:08:17,650 --> 00:08:20,793
these virtual machines will run with no issues.
182
00:08:22,070 --> 00:08:23,980
If you've done everything properly,
183
00:08:23,980 --> 00:08:26,593
now if you go again to the task manager,
184
00:08:27,770 --> 00:08:29,630
go to performance,
185
00:08:29,630 --> 00:08:32,853
you should see that virtualization is enabled.
186
00:08:34,020 --> 00:08:35,110
If you couldn't do that,
187
00:08:35,110 --> 00:08:37,240
please ask us in the Q and A section,
188
00:08:37,240 --> 00:08:39,660
and we'll be happy to help you.
189
00:08:39,660 --> 00:08:42,140
Keep in mind that you only need to do this,
190
00:08:42,140 --> 00:08:44,850
if you're running Windows or Linux
191
00:08:44,850 --> 00:08:47,933
as the host computer on your main computer,
192
00:08:49,070 --> 00:08:51,730
if you're running Apple macOS,
193
00:08:51,730 --> 00:08:53,320
then you do not need to do this
194
00:08:53,320 --> 00:08:55,293
and you should have skipped this part.
