2. Learn Network Hacking From Scratch (WiFi & Wired)

Learn Network Hacking From Scratch (WiFi & Wired) focuses on hacking networks using various attacks and tools (like black hat hackers) and then securing your network from these attacks.

It is a highly practical network penetration testing course that starts with setting up a Lab and installing the needed software so that you can practice it on your machine.

The 50 detailed videos in this course are divided into three main sections:

  1. The Pre-Connection Attacks – Where you’ll learn how to gather information about the target and the various types of attacks that you can perform on the target network.
  2. Gaining Access – You’ll use the gathered information to gain access to your target network by using various methods to crack the WEP/WPA/WPA2 encryption.
  3. Post Connection Attacks – After gaining access, this course will teach you how to go a step further and hack the devices that are connected to the target network.

You’ll learn about a variety of attacks and tools including packet injection, cracking WEP/WPA/WPA2 encryption and various types of Man-In-The-Middle (MITM) attacks.

After the completion of this course, you’ll be able to use more than 20 penetration testing tools in different scenarios.

3. Network Hacking Continued – Intermediate to Advanced

Network Hacking Continued – Intermediate to Advanced” is the continuation of the previously mentioned “Learn Network Hacking From Scratch (WiFi & Wired)” course from the same instructor.

Just like the previous course, this is a highly practical course that focuses on hacking networks using various attacks and securing them against these attacks.

You’ll learn various new concepts, attacks and tools such as disconnecting clients from WiFi networks, bypassing MAC filtering, discovering names of hidden networks, unlocking WPS on routers, gaining access to captive portals, creating a fake captive portal, advanced WPA/WPA2 cracking, bypassing HTTPS and much more.

Moreover, you’ll also learn to write your network hacking scripts and use them to attack the target network and the devices connected to the said network.

If you want to take your network hacking skills to the next level and write your custom network hacking scripts, then this course is for you.

Note that, this course covers advanced topics related to network hacking. Therefore, it is recommended to take the previous “Learn Network Hacking From Scratch (WiFi & Wired)” course first, if you are a beginner.
