Overview of this book

Penetration testing enables you to evaluate the security or strength of a computer system, network, or web application that an attacker can exploit. With this book, you'll understand why Python is one of the fastest-growing programming languages for penetration testing. You'll find out how to harness the power of Python and pentesting to enhance your system security. Developers working with Python will be able to put their knowledge and experience to work with this practical guide. Complete with step-by-step explanations of essential concepts and practical examples, this book takes a hands-on approach to help you build your own pentesting tools for testing the security level of systems and networks. You'll learn how to develop your own ethical hacking tools using Python and explore hacking techniques to exploit vulnerabilities in networks and systems. Finally, you'll be able to get remote access to target systems and networks using the tools you develop and modify as per your own requirements. By the end of this ethical hacking book, you'll have developed the skills needed for building cybersecurity tools and learned how to secure your systems by thinking like a hacker.

Keylogger

In this section, we will build a simple keylogger. A keylogger is a malware program that records the keystrokes of the user. It is one of the most common kinds of malware programs. Keyloggers are often used to steal passwords and other sensitive information, such as credit cards. Keyloggers are often made to be as silent as possible, which means that it is very hard to detect keyloggers. Let's try building a simple keylogger. You will need to install a module called pynput to build a keylogger. This module allows you to access keystrokes programmatically:

  1. To install this module, use the following command:
    pip install pynput

    This will install the module:

  2. Once the module is installed, we can import keyboard from this module:
    from pynput import keyboard
  3. Next, we will define a listener for listening to keystrokes. This listener will handle different cases on different events. Take a look at the following code:
    with keyboard.Listener(on_press=onPress, on_release...
