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.

Basic SELECT statements

Let's try to determine how many columns are being selected into page in the preceding screenshot. How much information is being selected and displayed on the login page that we got when we fired the query in the previous section? To do that, we're going to use the order by statement. We used order by 1 in the preceding section and that returned something acceptable, and order by 1000000 gave us an error, so let's try order by 10; we will see that we still get an error.

Try an order by 5 and we will see whether that it works. By performing this, we know that there are five columns being selected from a certain table, and it's the accounts table, which is then displayed on the login page. Let's build our own select statement and get it executed on the target computer. At the moment, the statement is Select * from accounts where username...
