Samsung Device Data Extraction in Oxygen Forensic® Detective

Samsung Device Data Extraction in Oxygen Forensic® Detective

Samsung has been leading the global market in manufacturing mobile phones, smartphones, and tablets for many years. Gaining access to digital evidence stored in popular Samsung devices has always been of vital importance to forensic investigators.

Currently, Samsung occupies 28,19% of the market share. Knowing this, Oxygen Forensic® Detective supports a majority of Samsung devices.

Samsung Exynos Dump

Oxygen Forensic® Detective supports a variety of Samsung devices within the Samsung Exynos method. Currently, over 190 Samsung devices are supported.

There are two approaches within the Exynos method:

  • Devices that run Android OS 7-9 and have Full-Disk Encryption (FDE). Physical image of the user partition is extracted from these devices.
  • Devices that run Android OS 9-11 and have File-Based Encryption (FBE). File system is extracted from these devices.

Oxygen Forensic® Detective offers users the option to either enter a known passcode or  brute force it. Passcode brute force is available for all supported devices with FDE and for devices running Android OS 10-11 with FBE.

Samsung Secure Folder data can be extracted from Samsung Exynos devices that have File-Based Encryption (FBE). No additional passcode is required for Samsung Secure Folder. Samsung Secure Folder allows users to store all files, photos, videos, and apps in a secure place within the mobile device.

Please note that the Samsung Exynos method works on Samsung devices with SPL no later than March 2022. If Samsung Exynos method is not compatible with a device under investigation, users have the option to run a full file system extraction or logical extraction using the Android Agent, APK Downgrade, or ADB backup from any unlocked Samsung Android device. The compatibility of these methods depends on the Samsung model.

Samsung Smart Switch backups

Oxygen Forensic® Detective also offers the ability to import, decrypt, and parse data from Samsung Smart Switch backups.

Samsung Smart Switch is a program used to transfer contacts, photos, music, messages, notes, and other media among Samsung Galaxy devices. Samsung Smart Switch backups can be created using Samsung Smart Switch on a desktop or with the mobile app.

This backup is a great alternative source of evidence when investigating Samsung devices.Currently, decryption is possible but only with a known password.

Once imported, the Samsung backup evidence set will include contacts, calls, messages, cached app pictures, apk files, Samsung web browser data, information about Wi-Fi connections, and access points.
