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.

Persistence

To be effective, the attacker must be able to maintain interactive persistence; they must have a two-way communication channel with the exploited system (interactive) that remains on the compromised system for a long period of time without being discovered (persistence). This type of connectivity is a requirement for the following reasons:

  • Network intrusions may be detected, and the compromised systems may be identified and patched.
  • Some exploits only work once because the vulnerability is intermittent or because exploitation causes the system to fail or change, rendering the vulnerability unusable.
  • Attackers may need to return multiple times to the same target for various reasons.
  • The target’s usefulness is not always immediately known at the time it is compromised.

The tool used to maintain interactive persistence is usually referred to by classic terms such as backdoor or rootkit. However, the trend toward long-term persistence...
