Overview of this book

This book starts with the basics of ethical hacking, how to practice hacking safely and legally, and how to install and interact with Kali Linux and the Linux terminal. You will explore network hacking, where you will see how to test the security of wired and wireless networks. You’ll also learn how to crack the password for any Wi-Fi network (whether it uses WEP, WPA, or WPA2) and spy on the connected devices. Moving on, you will discover how to gain access to remote computer systems using client-side and server-side attacks. You will also get the hang of post-exploitation techniques, including remotely controlling and interacting with the systems that you compromised. Towards the end of the book, you will be able to pick up web application hacking techniques. You'll see how to discover, exploit, and prevent a number of website vulnerabilities, such as XSS and SQL injections. The attacks covered are practical techniques that work against real systems and are purely for educational purposes. At the end of each section, you will learn how to detect, prevent, and secure systems from these attacks.

Discovering Vulnerabilities Automatically Using OWASP ZAP

Reflected XSS

Let's learn how to discover these kinds of vulnerabilities. The method is very similar to SQL injection. First, you browse through your target and try to inject into any textbox or URL that looks similar. Whenever you see a URL with parameters, try to inject something=something as parameters, or try to inject into textboxes. Let's have a look at a reflected XSS example. These are the non-persistent, non-stored vulnerabilities where we have to actually send the code to the target, and once the target runs the code, it will be executed on their machine.

Let's have a look at our DVWA website and log into it. Inside the DVWA Security tab on the left-hand side of the following screenshot, we are going to set the Script Security to low:

As we can see in the following screenshot, we can enter your name in the textbox, and it's just going to say Hello...
