[3.5] For an Android, which of the following files are of interest for a forensic examiner?

Question

BlackTom AI · Accepted Answer

When evaluating which Android files are of forensic interest, we consider images that contain user data, app data, and external storage content.
Option 1: apps.img, settings.img, media.img. While apps and settings may hold useful data, this trio omits the primary user data and external storage areas that are routinely examined in forensics. In particular, media.img is not the standard or most common artifact for a broad forensic sweep, making this set incomplete.
Option 2: kernel.img, firmware.img, bootloader.img. These are core system components and firmware-level artifacts. They can be relevant for device integrity or rooting analyses, but they do not directly represent user-generated content or typical user storage that an examiner would prioritize for evidentiary material.
Option 3: system.img, recovery.img, bootloader.img. This group includes essential system partitions and recovery, which can be relevant for tamper detection or OS-level investigations. However, like option 2, it lacks description of user data on the device’s main storage and external storage that are commonly sought in traditional forensic exams.
Option 4: cache.img, sdcard.img, Userdata-qemu.img. This combination covers cache data, external storage (sdcard), and user data (Userdata-qemu.img often represents user or app data with potential evidentiary value). These are the artifacts typically prioritized by forensic examiners because they are most likely to contain user-created files, messages, and app data relevant to investigations.
In summary, the fourth option aligns with standard forensic practice by including user data and external storage artifacts, whereas the other options focus on system or firmware components that, while may be informative in some contexts, are not as central to the routine collection of evidentiary material for Android devices.
