Mastering Kali Linux for Advanced Penetration Testing – Fourth Edition - Fourth Edition

By: Vijay Kumar Velu

Overview of this book

Remote working has given hackers plenty of opportunities as more confidential information is shared over the internet than ever before. In this new edition of Mastering Kali Linux for Advanced Penetration Testing, you’ll learn an offensive approach to enhance your penetration testing skills by testing the sophisticated tactics employed by real hackers. You’ll go through laboratory integration to cloud services so that you learn another dimension of exploitation that is typically forgotten during a penetration test. You'll explore different ways of installing and running Kali Linux in a VM and containerized environment and deploying vulnerable cloud services on AWS using containers, exploiting misconfigured S3 buckets to gain access to EC2 instances. This book delves into passive and active reconnaissance, from obtaining user information to large-scale port scanning. Building on this, different vulnerability assessments are explored, including threat modeling. See how hackers use lateral movement, privilege escalation, and command and control (C2) on compromised systems. By the end of this book, you’ll have explored many advanced pentesting approaches and hacking techniques employed on networks, IoT, embedded peripheral devices, and radio frequencies.

Denial of Service (DoS) attacks against wireless communications

The final attack against wireless networks that we’ll evaluate is DoS attacks, 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, into a wireless network can cause the 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 of data packets can make it unavailable for use; for example,...
