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.

Credential harvesting and escalation attacks

Credential harvesting is the process of identifying usernames, passwords, and hashes that can be utilized to achieve the objective set by the organization for a penetration testing/red team exercise. In this section, we will walk through three different types of credential harvesting mechanisms that are typically used by attackers in Kali Linux.

Password sniffers

Password sniffers are a set of tools/scripts that typically perform man-in-the-middle attacks by discovery, spoofing, sniffing traffic, and by proxying. From our previous experience, we noted that most organizations do not utilize SSL internally; Wireshark revealed multiple usernames and passwords.

In this section, we will explore bettercap to capture SSL traffic on the network so that we can capture the credentials of network users. bettercap is similar to the previous-generation ettercap command, with the additional capability to perform network-level spoofing and...
