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.

The OpenVAS network vulnerability scanner

Open Vulnerability Assessment System (OpenVAS) is an open-source vulnerability assessment scanner and also a vulnerability management tool often utilized by attackers to scan a wide range of networks, which includes 80,000+ vulnerabilities in its database. However, this is considered a slow network vulnerability scanner compared with other commercial tools, such as Nessus, Nexpose, and Qualys.

This tool is not preinstalled within Kali Linux 2021.4, hence it needs to be installed manually. Ensure your Kali is up to date and install the latest version of OpenVAS by running the sudo apt install gvm command. Once this is done, run the sudo gvm-setup command to set up OpenVAS. This setup will run all the relevant vulnerability databases (SCAP/NVT/CERT) and, once the script has successfully executed, it should create an admin user and generate a random password, as shown in Figure 4.17:
