00:01.240 --> 00:01.840
Okay.

00:01.840 --> 00:04.480
Welcome to backdoor section.

00:04.480 --> 00:12.480
In this section we are going to create a program to build a connection between hacker computer and also

00:12.520 --> 00:13.680
the victim.

00:13.680 --> 00:22.280
So you may ask what is a backdoor okay a backdoor is responsible for building a connection between hacker

00:22.280 --> 00:26.200
and a victim as you see that like right here.

00:26.240 --> 00:26.880
Okay.

00:26.920 --> 00:27.920
This is the victim.

00:28.280 --> 00:31.400
And this blue green okay.

00:31.400 --> 00:31.760
Sorry.

00:31.760 --> 00:36.200
Green line is it looks like a tunnel okay.

00:37.120 --> 00:43.440
Or a pipe that can move the data from here.

00:44.240 --> 00:46.600
So this is a backdoor.

00:47.440 --> 00:54.080
We have the victim computer and we have our program inside this whenever we want.

00:54.080 --> 01:00.440
It will build a connection for us between hacker computer and the victim.

01:00.440 --> 01:03.120
And we can move our data.

01:03.120 --> 01:09.920
We can, um, execute system command and do whatever we want with this victim computer.

01:10.720 --> 01:14.480
So right here we have two kinds of connection.

01:15.160 --> 01:17.960
We have direct connection.

01:18.560 --> 01:20.920
Direct connection is like this.

01:21.160 --> 01:23.960
When the hacker computer tries to connect the victim.

01:23.960 --> 01:24.760
Okay.

01:24.800 --> 01:28.800
So if we try to connect directly, it is not safe.

01:28.840 --> 01:29.360
Okay.

01:29.760 --> 01:36.200
Because whenever we try to connect, the victim firewall from this victim will understand that.

01:36.200 --> 01:42.960
And it will tell the user that you have a port open and someone is trying to connect using that port.

01:43.000 --> 01:44.840
It is not very good okay.

01:44.880 --> 01:46.880
So it is not safe for us.

01:47.480 --> 01:51.640
And the opposite of this is called reverse connection.

01:51.960 --> 01:57.800
Reverse connection is just like a normal connection for the user that irritate.

01:57.800 --> 02:02.000
They are trying to connect for example a web page, a web server or anything.

02:02.880 --> 02:10.400
So our program which is inside the victim computer will try to connect, will try to build a connection

02:10.440 --> 02:11.280
for us.

02:11.680 --> 02:21.310
And we can use that connection to do whatever we want with victim computer or victim laptop.

02:21.790 --> 02:26.750
So here we can execute our the system command.

02:26.910 --> 02:28.590
We can download files.

02:28.590 --> 02:31.870
We can execute some even file.

02:32.110 --> 02:43.990
And also we can for example hack the Mach microphone, the PC camera and a lot of things that we can

02:44.030 --> 02:44.150
do.

02:44.190 --> 02:44.390
Okay.

02:44.430 --> 02:47.390
We will be seeing them in the future.

02:48.350 --> 02:51.070
And it is called reverse connection.

02:51.070 --> 02:59.030
So here you learn what is a backdoor, what is a direct connection and what is reverse connection.

02:59.030 --> 03:04.110
So let's go and start building our backdoors okay.

03:04.150 --> 03:05.110
Backdoor program.

03:05.630 --> 03:12.470
And we will be sending that to victim computer and build this connection for us.

03:12.470 --> 03:18.750
And we can run the system command on victim and you will see the result.

03:18.950 --> 03:21.990
So I'm not going to talk too much.

03:22.030 --> 03:24.710
Let's go and see that practically.
