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.

Physical attacks at the console

In this section, we will explore different types of attack that are typically performed on a system where physical access is possible.

samdump2 and chntpw

One of the most popular ways to dump password hashes is to utilize samdump2. This can be done by turning on the power of the acquired system and then booting it through our Kali USB stick by making the required changes in the BIOS (say, in Lenovo, one can press F12 to bring up the boot menu and select the USB):

  1. Once the system is booted through Kali, by default the local hard drive must be mounted as a media drive (assuming the media drive is not encrypted with BitLocker or something similar), as shown in Figure 5.2:

  2. If the drive is not mounted by default, the attackers can manually mount the drive by running the following commands:
    mkdir /mnt/target1
    mount /dev/sda2 /mnt/target1
    
  3. Once the system...
