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.

Wireless modes – managed and monitor

Now we know that the MAC address is used to make sure that the packet goes in the right direction, so each packet has a source MAC and a destination MAC, and it flows from the device that has the source MAC to the device that has the destination MAC. This is how wireless cards work in the default mode. So, if we go into the Kali machine and use iwconfig, in the following screenshot, you can see that we have a wireless card, named wlan0, and that the default mode is called managed mode:

So, basically, in this mode, our wireless device will only receive packets, or will only try to capture packets that have our device's MAC address as the destination MAC. It will only capture packets that are actually directed to our computer.

What we want to do, however, is enable it to capture any packet that's around us—any packet...
