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.

The dangers of SQLi

In this section of the chapter, we will focus on why SQL injections are so important and so dangerous. The reason is because they are found everywhere; a lot of big websites have these kind of exploits, such as Yahoo and Google. They're very hard to protect against and it's very easy to make a mistake and make these exploits available for misuse. The other reason that they're very dangerous is because they give the hacker access to the database. In many scenarios, if we find an SQLi, we don't need to upload a PHP shell or get a reverse connection. There is really no need to upload anything and increase the danger of being caught because, if we have access to the database, we pretty much have everything we need. We have usernames and passwords, and we can log in with a normal username and password as a normal user; if we are looking for sensitive...
