Chapter 2. Do It Yourself – Low-Level Techniques

In the continuously evolving environment of the mobile world, digital forensic examiners can neither always nor exclusively rely on commercially available tools. The ability to handle low-level techniques is a must. In this chapter, we will go deep into some commonly used techniques to carve files, manually extract GPS data, and explain how things are at a lower level. This chapter will also cover some techniques for extracting strings from different objects (for example, smartphone images), and will describe the basics of applying reverse engineering on smartphone applications.

We will look at the following topics in this chapter:

  • Getting acquainted with file carving

  • Extracting metadata – GPS analysis

  • String dump and analysis

  • Encryption versus encoding versus hashing

  • Decompiling and disassembling

So let's get started with file carving!
