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

Summary


In this chapter, we learned about file recovery and data extraction using three readily-available tools within Kali Linux. We first performed file carving using the very impressive Foremost, which searched the entire image for supported file types within the file header and footers. We then did the same using the newer Scalpel, but had to make a slight modification by selecting the file types we wished to carve. Both Foremost and Scalpel presented us with an audit.txt file summarizing the carve list and its details along with subfolders containing the actual evidence. 

Bulk_extractor is a wonderful tool that carves data and also finds useful information such as email addresses, visited URLs, Facebook URLs, credit card numbers, and a variety of other information. Bulk_extractor is great for investigations requiring file recovery and carving, together with either Foremost or Scalpel, or even both.

Now that we've covered file carving and recovery, let's move on to something more analytical...
