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.

Packet sniffing basics

In the last chapter, we set the Wi-Fi card into monitor mode, so that we can sniff packets that are within our Wi-Fi range, even if they're not directly connected to our device, and even if we are not connected to a network with a username and password. Now, we're going to use a tool called airodump-ng, part of the Aircrack-ng suite. It's a packet sniffer, and it allows us to capture all of the packets around us. We can run it against all of the networks around us and collect any packets within our range. We can also run it against a certain access point (AP) so that we only collect packets from a certain Wi-Fi network.

First, let's look at how to run the program. You'll need your Wi-Fi card in monitor mode; in our case, the name of the Wi-Fi card is wlan0. So, we'll run the airodump-ng wlan0 command—it's as simple...
