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.

Detecting ARP poisoning

Let's take a look at how to detect ARP poisoning attacks. First of all, we need to gain an understanding of the ARP table. On our Windows device, which is the device that we always attack, we are going to run the arp -a command to list all the entries in the ARP table. Each computer has an ARP table, and that table associates IP addresses with MAC addresses. We have the IP address of a router, which is 10.0.2.1 and is associated with the MAC address 52-54-00-12-35-00, as shown in the following screenshot:

ARP poisoning works via trusted requests; as you can see in the previous screenshot, when a request is trusted, responses are accepted by the client even if a request isn't actually sent. The hacker sends a response to the client telling them that they are the router, which is automatically trusted and then accepted. Hacker will now send another...
