Course Description

Last Update: May 2024


Welcome to this comprehensive course on Network Hacking! In this course, you will start as a beginner with no previous knowledge about penetration testing or hacking and by the end of it you'll be at an intermediate level being able to hack into networks and connected devices like black-hat hackers and secure them like security experts.

This course is focused on the practical side of penetration testing without neglecting the theory. Before jumping into hacking you will first learn how to set up a lab and install needed software (works on Windows, Mac OS X and Linux), then the course is structured in a way that will take you through the basics of linux, computer systems, networks and how devices communicate with each other, then you will learn how to exploit this method of communication to carry out a number of powerful attacks.


The Course is Divided into three main sections: 

  1. Pre-connection attacks: In this section you will learn how networks work, how devices communicate with each other and how the information is transferred in a wireless networks. You will also learn some basic terminology, what is a channel ? MAC address ? what is managed mode ? What is monitor mode  and how to enable it ? what is sniffing and what is it limited to ? so in this section we still don't know much about penetration testing , all we have is a computer and a wireless card connected to it, you will learn how to start gathering information using your wi-fi card (packet sniffing) and you will learn  how to control connections around you (ie: deny/allow devices from connecting to networks) without knowing the password of the target network.

  2. Gaining Access: Now that you gathered information about the networks around you, in this section you will learn a number of methods to crack the key and get the password to your target network whether it uses WEP, WPA or even WPA2.

  3. Post Connection attacks: Now that you have the key, you can connect to the target network, in this section you will learn a number of powerful techniques that allow you to gather comprehensive information about the connected devices, see anything they do on the internet (such as login information, passwords, visited urls, images, videos, etc.), redirect requests, inject evil code in loaded pages and even gain full control over connected clients! All the attacks here work against both wireless and wired networks. You will also learn how to create a fake WiFi network, attract users to connect to it and use all of the above techniques against the connected clients.


All the attacks in this course are practical attacks that work against any wireless enabled device , ie: it does not matter if the device is a phone , tablet laptop, etc. These attacks also work against all operating systems (Windows, OSX, Linux IOS, Android, ect.).  in each technique you will understand the theory behind it and how it works, then you'll learn how to use that technique in a real life scenario, so by the end of the course you'll be able to modify these techniques or combine them to come up with more powerful attacks and adopt them to different scenarios and different operating systems.

With this course you'll get 24/7 support, so if you have any questions you can post them in the Q&A section and we'll respond to you within 15 hours.


Notes:

  • This course is created for educational purposes only and all the attacks are launched in my own lab or against devices that I have permission to test

  • This course is totally a product of Zaid Sabih & zSecurity, no other organization is associated for certification exam for the same. Although, you will receive Course Completion Certification from Udemy, apart from that No OTHER ORGANIZATION IS INVOLVED

This course is just amazing, seriously ! Zahid is an excellent teacher and the lessons are short, well thought and very easy to understand. Zahid and his asociate will always give a quick and useful help if you get stuck (and you will) on any lessons. I finished the entire course and I'm very glad of what I've learned so far, I feel that I have a real grasp on the tools and basic concepts. Now and can start to go deeper from there ! Thx Zahid !

I had previously learned ethical hacking from scratch course and expected this to provide more ways to hack wifi passwords, but instead its the same information and it puts more attention on post-connection attacks rather than how to actually break the wpa/wpa2 to get the password. Really dissapointed, it looks like Zaid thinks everyone uses some silly passwords as 'iloveyou' or 'football' for their wifi. the reality is that people are not interested in changing the password which is generated by manufacturer, so if the password looks like sqUa638PZXxaUwYjkOOnA131Yug, you are stuck for a long time trying to break it and this course provides no help at all.

The step by step is really helpful. And, since I use multiple machines, I can follow along on one while actually doing the work on the other. Fortunately, my machine specs are a little higher than the one being used in the video, so I have no worries there. And I am using OSX so that makes it easier as well. ,

Yeah

I needed to learn computer security skills ethically without ever stepping outside of legal boundaries. This course allowed me to rapidly get going on and continue my journey to becoming a certified security professional.

The explanation is exceptionally clear and easy to follow. The course is also well-structured.
