The ethical hacker acts in a way that intended to find weakness and vulnerabilities in the target system in order to protect it against real-world threats.

Covering topics including web application scanning and exploitation, fuzzing, penetration testing, forensics, and open source intelligence, this course will teach you about one specific skill: command injection.

You will learn why command injection matters, how to hack a server using command injection, how to prevent command injection in your own web apps and more. The course includes a practice section that lets you practice what you learn.

While you can do this kind of hacking from any system, I recommend using Kali Linux. It's a system created for security and hacking. The distribution includes popular hacking and security tools like metasploit, nmap, John the ripper and many more. However, it is possible to hack from any Linux system if you are willing to install the tools.

This is a beginners course. If you are a beginner ethical hacker and want to improve your skills, this course is for you. You don't need any prior knowledge before starting this course. The course has a focus on hacking web applications that expose the command line interface. Some Linux knowledge is beneficial.
