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.

Wordlist cracking

Now that we've captured the handshake from our target AP and we have a wordlist ready to use, we can use aircrack-ng to crack the key for the target AP. The aircrack-ng is going to go through the wordlist file, combine each password with the name of our target AP, and create a Pairwise Master Key (PMK). The PMK is created by using an algorithm called the PBKDF2, it's not like just combining the password and the BSSID; it's encrypting them in a certain way, and it compares the PMK to the handshake. If the PMK was valid, then the password that was used is the password for the target AP; if it wasn't valid, then aircrack-ng tries the next password.

We use aircrack-ng, the name of the file that contains the handshake, test-handshake-01.cap, and -w and the name of the wordlist, wordlist. The command is as follows:

aircrack-ng test-handshake-01...
