1
00:00:00,600 --> 00:00:06,400
The first penetration testing section in this course is going to be the network hacking section.

2
00:00:07,260 --> 00:00:13,760
The reason why I chose to start with this is because everything you think of it is connected to a network.

3
00:00:14,060 --> 00:00:19,980
So whether your target is a personal computer, whether it's a server, whether it's a company,

4
00:00:19,980 --> 00:00:21,780
or even if it's just a website.

5
00:00:21,940 --> 00:00:25,840
All of these systems are actually connected to a network.

6
00:00:26,420 --> 00:00:30,280
Literally, when you just connect to the
Internet, you're connecting to a network

7
00:00:30,280 --> 00:00:33,040
because the Internet is just a really really big network.

8
00:00:34,020 --> 00:00:38,100
So it is very important that you understand how networks work

9
00:00:38,200 --> 00:00:43,980
and how devices communicate with each other, before we actually move into the next sections.

10
00:00:44,620 --> 00:00:49,180
So this section is actually going to be divided into three sub sections.

11
00:00:49,800 --> 00:00:57,140
In the first sub section, we're going to talk about all of the attacks that you can do before connecting to a network.

12
00:00:57,140 --> 00:01:02,760
So you literally just have a computer with a network interface, possibly a Wi-Fi adapter

13
00:01:03,920 --> 00:01:08,000
and we're going to see what can you do now before even connecting to anything.

14
00:01:08,560 --> 00:01:15,980
In the second sub section, I'm gonna show you how to crack Wi-Fi keys and gain access to Wi-Fi networks.

15
00:01:15,980 --> 00:01:20,300
Whether they use WEP, WPA or WPA2.

16
00:01:21,800 --> 00:01:27,000
Once you have the access, you can move to the third section, which will apply for both,

17
00:01:27,020 --> 00:01:29,720
Wi-Fi and wired networks.

18
00:01:30,620 --> 00:01:37,560
All of the attacks that you'll learn in the third sub section apply whenever you are able to connect to the network,

19
00:01:37,560 --> 00:01:40,660
once you're able to gain access to the network.

20
00:01:41,500 --> 00:01:47,020
And here is where the real fun starts, because you're going to learn a number of powerful attacks,

21
00:01:47,060 --> 00:01:53,280
that will allow you to intercept the connections in the network and capture everything sent in it,

22
00:01:53,280 --> 00:01:58,420
including usernames, passwords, URLs, chat messages and so on.

23
00:01:59,620 --> 00:02:05,020
Not only that, you'll also be able to modify data as it's being sent in the air.

24
00:02:05,020 --> 00:02:10,560
So you'll be able to control the requests, surf people take updates, inject evil code

25
00:02:10,900 --> 00:02:15,040
into the pages that they load and
so many other cool things.

26
00:02:15,700 --> 00:02:23,360
So everything in the third section will apply for both Wi-Fi and wired networks.
