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.

Discovering Vulnerabilities Automatically Using OWASP ZAP

Detecting Trojans manually

The Trojans we've created so far are amazing; they can bypass antivirus programs they run two pieces of code, the first one runs in the background, which runs our own code and does what we want it to do, such as opening a port or connecting back to us and giving us a shell, and it runs another piece of code that the user expects. It could display an image, play an MP3, or display a PDF file. This functionality makes it very difficult to detect, so the best thing to do is to check the properties of the file and make sure that it is what it's claiming to be. In the following screenshot, we have a Packt image and we can see that it's a .jpg, so it looks like a picture, it has an icon, and if we run it we will get a picture, like we saw in Chapter 13, Client-Side Attacks - Social Engineering:
