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.

SQL Injection Vulnerabilities

In this chapter, we are going to study SQL Injection (SQLi) vulnerabilities. To gain insight into these vulnerabilities, we will first learn about SQL, look at the reasons why we are studying SQL, and how

dangerous SQLi is exactly. Moving ahead, we will learn some techniques to discover SQL injections. Then, we will learn how we can bypass SQLi authorization and how to discover SQLi using the GET method. We will also see how we can work around SQL commands and discover tables using commands. In the loadfile section, we will see how we can implement SQLi on server files. Then, we are going to learn how we can use a tool called sqlmap. Finally, will look at techniques we can use to prevent dangerous SQL injections.

In this chapter, we'll cover the following topics:

  • What is SQL?
  • The dangers of SQLi
  • Discovering SQLi
  • SQLi authorization bypass
  • Discovering...
