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.

Horizontal escalation and lateral movement

In horizontal escalation, the attacker retains their existing credentials but uses them to act on a different user’s account. For example, a user on compromised system A attacks a user on system B in an attempt to compromise them.

The horizontal move that attackers would utilize is from the compromised system.

This is used to extract the hashes of common usernames such as Itsupport and LocalAdministrators, or known default user administrators to escalate the privileges horizontally on all the available systems that are connected to the same domain. For example, here, we will use CME to run the same password hashes across an IP range to dump all of the passwords on a hacker-controlled shared drive:

crackmapexec smb 10.10.10.1/24 -u <Username> -d local -H <Hashvalue> --sam

Figure 11.14 shows the output of a SAM dump being run on an entire IP range to extract SAM password hashes without planting any executables...
