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.

Scraping

A technique that attackers utilize to extract a large number of datasets from websites, whereby the extracted data is stored locally in a filesystem, is called scraping, or web scraping. In the following section, we will utilize some of the most commonly used tools in Kali Linux to perform scraping.

Gathering usernames and email addresses

theHarvester is a Python script that searches through popular search engines and other sites for email addresses, hosts, and sub-domains. Using theHarvester is relatively simple, as there are only a few command switches to set. The options are as follows:

  • -d: This identifies the domain to be searched, usually the domain or target’s website.
  • -b: This identifies the source for extracting the data; it must be one of the following: Bing, BingAPI, Google, Google-Profiles, Jigsaw, LinkedIn, People123, PGP, or All.
  • -l: This limiting option instructs theHarvester to only harvest data from a specified number...
