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.

Enumerating hosts

Host enumeration is the process of gaining specific particulars regarding a defined host. It is not enough to know that a server or wireless access point is present; instead, we need to expand the attack surface by identifying open ports, the base operating system, services that are running, and supporting applications. This is highly intrusive and, unless care is taken, such activity will be detected and logged by the target organization.

Live host discovery

The first step is to run network ping sweeps against a target address space and look for responses that indicate that a particular target is live and capable of responding. Historically, pinging is referred to as the use of ICMP; however, TCP, UDP, ICMP, and ARP traffic can also be used to identify live hosts.

Various scanners can be run from remote locations across the internet to identify live hosts. Although the primary scanner is Nmap, Kali provides several other applications that are also useful...
