Hello and welcome.

My name is Zaid.

I'm an ethical hacker, a computer scientist.

And I'll be your instructor in this course.

This course is going to be highly practical, but it won't neglect the theory.

So we'll start by covering some terminology.

Then I'm going to show you how to install the needed software in order to write Python programs and

practice hacking safely.

Throughout the course.

We're going to learn by example, so we'll never have any boring plane program and lectures.

We will always be building something exciting.

And I'm going to teach you programming as we build these exciting programs.

The first program we'll write is a mark changer.

This is a very simple program that can be used to change the Mac address.

Don't worry if you don't know what a mac address is or why you want to change it, we will cover all

of that later on.

Basically, the whole point of writing this program is to introduce you to Python basics such as writing

functions, variables, handling user input checks and so on.

In here you'll learn how to properly model a problem, write an algorithm to solve this problem, and

then write Python code to implement this solution.

Once we have the basics covered, we're going to start writing a little bit more complex programs.

So we'll start with a network scanner, which is a program that can discover all clients connected to

the same network and display their IP address and MAC address in here.

I'm going to introduce you to KP and I'm going to teach you how to send and receive ARP responses and

analyze them.

I will also introduce you to dictionaries and lists and we'll see how to use them and all the operations

that we can invoke on them.

Next, we'll dive deeper into networking.

We're going to learn what r.p is, what it's used for, what is ARP spoofing, and how to write a Python

program to run an ARP spoofing attack.

As we do this, you'll learn more about Skype, analyzing network layers, handling exceptions, loops

and more.

Then we're going to dive even deeper in networking.

So you're going to learn how to sniff data sent or received by any computer connected to the same network

as us.

This means we'll be able to see visited websites, login information, passwords and pretty much everything

they do on the internet.

You'll also learn how to analyze data sent in the different layers in each packet and how to modify

this data.

So we'll be able to inject code and HTML pages loaded by any computer on the same network.

We'll be able to replace downloads and even spoof DNS requests to any destination we want.

We'll learn all of this by writing a sniffer, a dense puffer, a code injector and a file interceptor.

Once done with all of this, we'll move to a really exciting section where you'll learn how to write

malware.

We'll start with writing simple evil programs so programs that can download the file, execute code,

send a report by email, and then I'm going to show you how to combine all of these programs to suit

different scenarios and execute powerful attacks.

Then we're going to advance into writing more complex malware, and we'll start by writing a backdoor.

A backdoor is a program that gives you full control over the system that it gets executed on.

We're going to implement this using sockets and you're going to learn how to establish a connection

between two devices and transfer data between them.

This is very useful because it can be used in so many other scenarios other than hacking.

So you can use it to create a web server, a chat program and so on.

Then we're going to build more cool features in this backdoor so that we can use it to execute system

commands remotely on the target computer, download and upload files and maintain our access even if

the system restarts.

Then we will implement a keylogger, which is a program that registers every keystroke entered on the

keyboard and send us a report by email.

As we do this, I'm going to teach you about recursive functions, threading and object oriented programming.

In the last part of the section, I'm going to show you how to package all of the programs that we built

so far so that they can run on any operating system on Windows, OSX and Linux.

Not only that, but I'm also going to show you how to convert these programs into Trojans so they look

and function just like any other file type, like an image or a PDF.

Finally, we'll move to the website hacking section where you learn how websites work and how to communicate

with websites using Python.

And then we'll build a number of information gathering programs that can be used to discover files,

directories and subdomains.

Then we're going to write a program that can be used to guess the login information of any login page.

As we do this, you're going to learn how to read the HTML code of any web page, analyze it, and extract

the useful parts from it.

Finally, we're going to build a generic vulnerability scanner.

This is a program that takes a website as an input and scans the whole website for weaknesses and vulnerabilities.

Once done, it's going to show us a report of all the discoveries.

And we're going to write this program in a way so that it can discover any type of vulnerability.

As we write this, you're going to learn more about object oriented programming and how to structure

your program in a way so that it can be easily extended.
