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.

Extracting data physically with dd

The dd command should be familiar to any examiner who has done traditional hard drive forensics. dd is a Linux command-line utility used by definition to convert and copy files, but is frequently used in forensics to create bit-by-bit images of entire drives. Many variations of dd also exist and are commonly used, such as dcfldd, dc3dd, ddrescue, and dccidd. As dd is built for Linux-based systems, it is frequently included on Android platforms. This means that a method for creating an image of the device often already exists on the device!

The dd command has many options that can be set; only the forensically important options are going to be covered in the following list. A full list of command options can be found at http://man7.org/linux/man-pages/man1/dd.1.html. The format of the dd command is as follows:
