Summary
Extracting data from an Android device is one of the crucial steps during the course of an investigation. Once the device is accessible, an examiner can extract the data using manual, logical, or physical data extraction techniques. Logical techniques extract the data by interacting with the device using tools such as ADB. Physical techniques, on the other hand, access a larger set of data; they are complex and require a great deal of expertise to perform. Imaging a device produces a bit-by-bit image of the device, which is later analyzed using tools. Imaging a device is one of the primary steps to ensure that the data on the device is not modified.
In the next chapter, we will see how to extract relevant data such as call logs, text messages, browsing history, and so on from an image file. We will also cover data recovery techniques, using which we can recover the data deleted from a device.
