Digital Forensics with Kali Linux

Overview of this book

Kali Linux is a Linux-based distribution used mainly for penetration testing and digital forensics. It has a wide range of tools to help in forensics investigations and incident response mechanisms. You will start by understanding the fundamentals of digital forensics and setting up your Kali Linux environment to perform different investigation practices. The book will delve into the realm of operating systems and the various formats for file storage, including secret hiding places unseen by the end user or even the operating system. The book will also teach you to create forensic images of data and maintain integrity using hashing tools. Next, you will also master some advanced topics such as autopsies and acquiring investigation data from the network, operating system memory, and so on. The book introduces you to powerful tools that will take your forensic abilities and investigations to a professional level, catering for all aspects of full digital forensic investigations from hashing to reporting. By the end of this book, you will have had hands-on experience in implementing all the pillars of digital forensics—acquisition, extraction, analysis, and presentation using Kali Linux tools.

Revealing Evidence Using DFF

Bulk_extractor


Bulk_extractor is the third and final tool that we'll cover in this chapter. Foremost and Scalpel, as we've seen so far, are quite impressive at file recovery and carving, but are limited to specific file types. For further extraction of data, we can use Bulk Extractor.

While Foremost and Scalpel can recover images, audio, video, and compressed files, Bulk Extractor extracts several additional types of information that can be very useful in investigations.

Although Bulk Extractor is quite capable of recovering and carving image, video, and document type files, other data that can be carved and extracted by Bulk Extractor includes:

  • Credit card numbers
  • Email addresses
  • URLs
  • Online searches
  • Website information
  • Social media profiles and information
