Overview of this book

Many forensic examiners rely on commercial, push-button tools to retrieve and analyze data, even though there is no tool that does either of these jobs perfectly. Learning Android Forensics will introduce you to the most up-to-date Android platform and its architecture, and provide a high-level overview of what Android forensics entails. You will understand how data is stored on Android devices and how to set up a digital forensic examination environment. As you make your way through the chapters, you will work through various physical and logical techniques to extract data from devices in order to obtain forensic evidence. You will also learn how to recover deleted data and forensically analyze application data with the help of various open source and commercial tools. In the concluding chapters, you will explore malware analysis so that you’ll be able to investigate cybersecurity incidents involving Android malware. By the end of this book, you will have a complete understanding of the Android forensic process, you will have explored open source and commercial forensic tools, and will have basic skills of Android malware identification and analysis.

Summary

In this chapter, we discussed several techniques that are used for physically imaging internal memory or SD cards, and some of the common problems associated with them:

Technique

Problems associated

dd

  • Usually preinstalled on device
  • May not work on MTD blocks
  • Does not obtain the out-of-band area

nanddump

  • Not commonly found on the device, must be pushed to device
  • Works well with MTD blocks
  • May obtain the out-of-band area, based on options in the binary used

Additionally, each imaging technique can be used to either save the image on the device (typically on the SD card), or used with netcat to write the file to the examiner's computer:

Features

Writing to SD card

  • Easy, doesn't require additional binaries to be pushed to the device
  • Familiar to most examiners
  • Cannot be used if SD card is symbolically linked...
