Digital Forensics with Kali Linux - Second Edition

By: Shiva V. N. Parasram

Overview of this book

Kali Linux is a Linux-based distribution that's widely used for penetration testing and digital forensics. It has a wide range of tools to help for digital forensics investigations and incident response mechanisms. This updated second edition of Digital Forensics with Kali Linux covers the latest version of Kali Linux and The Sleuth Kit. You'll get to grips with modern techniques for analysis, extraction, and reporting using advanced tools such as FTK Imager, hex editor, and Axiom. Updated to cover digital forensics basics and advancements in the world of modern forensics, this book will also delve into the domain of operating systems. Progressing through the chapters, you'll explore various formats for file storage, including secret hiding places unseen by the end user or even the operating system. The book will also show you how to create forensic images of data and maintain integrity using hashing tools. Finally, you'll cover advanced topics such as autopsies and acquiring investigation data from networks, operating system memory, and quantum cryptography. By the end of this book, you'll have gained hands-on experience of implementing all the pillars of digital forensics: acquisition, extraction, analysis, and presentation, all using Kali Linux tools.

Image acquisition using DD

Should you also wish to use the DD tool, the commands and usage are very much the same.

You may want to first ensure that you can access the DD tool by running dd –-help. If the dd command cannot be found, update Kali Linux by running the apt-get update command and then running the dd –-help command again:

Attach the storage you wish to acquire. For this example, I'll be using an older 2 GB Sony Pro Duo card that I'd like to image and analyze.

Run the fdisk –l command in the Terminal to view the device details. In the following screenshot, we can see that the device is recognized as /dev/sdb and is 1.89 GB with a default sector size of 512 bytes:

I'll also manually create hashes to verify the integrity of the created images by comparing the hashes of the images with...
