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.

File upload vulnerabilities

In this chapter, we're going to have a look at file upload vulnerabilities. This is the simplest type of vulnerability because it allows us to upload any type of file. For example, if the target computer can understand PHP, then we can upload any PHP file or a PHP shell and get full control over the target computer.

If the target computer or the target server understands Python then we can just upload Python code or Python Shell. We can create these shells using Veil-Evasion or Metasploit, or we can use our own PHP or Python Shell.

In the next section, we are going to have a look at a tool called Weevely that generates PHP shells and allows us to gain access to and do a number of cool things on the target computer.
