Overview of this book

This book will take you, as a tester or security practitioner through the journey of reconnaissance, vulnerability assessment, exploitation, and post-exploitation activities used by penetration testers and hackers. We will start off by using a laboratory environment to validate tools and techniques, and using an application that supports a collaborative approach to penetration testing. Further we will get acquainted with passive reconnaissance with open source intelligence and active reconnaissance of the external and internal networks. We will also focus on how to select, use, customize, and interpret the results from a variety of different vulnerability scanners. Specific routes to the target will also be examined, including bypassing physical security and exfiltration of data using different techniques. You will also get to grips with concepts such as social engineering, attacking wireless networks, exploitation of web applications and remote access connections. Later you will learn the practical aspects of attacking user client systems by backdooring executable files. You will focus on the most vulnerable part of the network—directly and bypassing the controls, attacking the end user and maintaining persistence access through social media. You will also explore approaches to carrying out advanced penetration testing in tightly secured environments, and the book's hands-on approach will help you understand everything you need to know during a Red teaming exercise or penetration testing

DoS attacks against wireless communications

The final attack against wireless networks that we'll evaluate is the DoS attack, where an attacker deprives a legitimate user of access to a wireless network or makes the network unavailable by causing it to crash. Wireless networks are extremely susceptible to DoS attacks, and it is difficult to localize the attacker on a distributed wireless network. Examples of DoS attacks include the following:

  • Injecting crafted network commands, such as reconfiguration commands, onto a wireless network can cause a failure of routers, switches, and other network devices.
  • Some devices and applications can recognize that an attack is taking place and will automatically respond by disabling the network. A malicious attacker can launch an obvious attack and then let the target create the DoS itself!
  • Bombarding the wireless network with a flood...
