Okay.
Welcome to backdoor section.
In this section we are going to create a program to build a connection between hacker computer and also
the victim.
So you may ask what is a backdoor okay a backdoor is responsible for building a connection between hacker
and a victim as you see that like right here.
Okay.
This is the victim.
And this blue green okay.
Sorry.
Green line is it looks like a tunnel okay.
Or a pipe that can move the data from here.
So this is a backdoor.
We have the victim computer and we have our program inside this whenever we want.
It will build a connection for us between hacker computer and the victim.
And we can move our data.
We can, um, execute system command and do whatever we want with this victim computer.
So right here we have two kinds of connection.
We have direct connection.
Direct connection is like this.
When the hacker computer tries to connect the victim.
Okay.
So if we try to connect directly, it is not safe.
Okay.
Because whenever we try to connect, the victim firewall from this victim will understand that.
And it will tell the user that you have a port open and someone is trying to connect using that port.
It is not very good okay.
So it is not safe for us.
And the opposite of this is called reverse connection.
Reverse connection is just like a normal connection for the user that irritate.
They are trying to connect for example a web page, a web server or anything.
So our program which is inside the victim computer will try to connect, will try to build a connection
for us.
And we can use that connection to do whatever we want with victim computer or victim laptop.
So here we can execute our the system command.
We can download files.
We can execute some even file.
And also we can for example hack the Mach microphone, the PC camera and a lot of things that we can
do.
Okay.
We will be seeing them in the future.
And it is called reverse connection.
So here you learn what is a backdoor, what is a direct connection and what is reverse connection.
So let's go and start building our backdoors okay.
Backdoor program.
And we will be sending that to victim computer and build this connection for us.
And we can run the system command on victim and you will see the result.
So I'm not going to talk too much.
Let's go and see that practically.
