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.

Bypassing a hidden SSID

ESSID is the sequence of characters that uniquely identify a wireless local area network. Hiding the ESSID is a poor method of attempting to achieve security through obscurity; unfortunately, the ESSID can be obtained by doing either of the following:

  • Sniffing the wireless environment and waiting for a client to associate to a network and then capturing that association
  • Actively deauthenticating a client to force the client to associate and then capturing that association

The aircrack tools are particularly well suited to capture the data that’s needed to unhide a hidden ESSID, as shown in the following steps:

  1. At the command prompt, confirm that wireless is enabled on the attacking system by entering the following command:
    sudo airmon-ng
    
  2. Next, use the following ifconfig command to review the available interfaces and to determine the exact name that’s used by your wireless system: ...
