In this section, we're going to look at an example of a very simple thing: a backdoor. Some programs or services are shipped with backdoors embedded in them. We're going to exploit this, and we are choosing this very simple exploit because we are going to look at a framework called Metasploit. We will be using this framework a lot. We are going to start with something simple and then we're going to go deeper into the framework. First, let's look at how we can find that exploit. Again, using the same method that we've always been using, we have an Nmap scan; as we know, we're going to go on each port and Google them, looking for exploits. We are going to Google the service name vsftpd 2.3.4 exploit. It's the service name followed by exploit. We can see that the first result comes in from a website...

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.
