 +
*The Glaze Camera is a built-in camera solution for a refrigerator that supports food management. I was not able to find a lot of technical details about this service, but the GitHub opensource script Python Family Hub mentions it. Some non-technical details about the service are also available here.

*The application stores its data in the "\user\home\owner\apps_rw\org.tizenglazecamera\". In the provided dataset three JPG pictures of the content of the fridge were found in the "\shared\trusted\"subfolder. All of them were taken on 7th February 2018 at 18:41:12 UTC.
 +
===Tizen Browser===
 +
 
 +
*The Tizen OS 3.0 has a default browser named "Tizen Browser", based on Chromium. Details about the browser are available on the tvmode.org website. The Tizen Browser stores information in 2 main locations in the user partition: the "\user\home\owner\apps_rw\org.tizen.browser\" folder and the "\user\data\browser-provider\database\" folder.

 +
*The "\user\home\owner\apps_rw\org.tizen.browser\data\chromium-elf\cache" folder contains browser cache items. As the Tizen Browser is based on Chromium, the Cache can be parsed with ChromeCacheView or Hindsight.
 +
===Glympse Family Map===
 +
*The Glympse Family Map is a location-sharing service "which allows users to seamlessly share their location using a variety of devices within the Tizen ecosystem".
 +
*This app is based on Chromium and it also uses a Cache folder ("\user\home\owner\appr_rw\gfamilymap\data\chromium-elf\cache\") that can be parsed with ChromeCacheView or Hindsight.
 +
*By analyzing the images stored in the cache folder I was able to find some Google Maps images geolocated at the VTO Labs headquarter, where probably the fridge was used and then acquired.
 +
*Some logs files about the Glympse service are stored in the "\user\home\owner\appr_rw\com.glympse.tizen.frapp.service\data\glympse". They seem to contain information about sync with the Glympse service, but more research and testing is needed.
 +
===Samsung Connect===
 +
*The "\user\home\owner\apps_rw\com.samsung.samsung-connect" folder contains Samsung Connect App data. This app "provides users a simple, unified way to control and monitor smart devices in one app".
 +
*The "\user\home\owner\apps_rw\com.samsung.samsung-connect\shared\data\sc.db" file contains references to other devices: in the provided dataset a "SAMSUNG SM-G930V" and a "Pixel 2" (table "device_table").
 +
===Energystar===
 +
*The "\user\home\owner\apps_rw\org.tizen.energystar" folder contains energy information. The "\user\home\owner\apps_rw\org.tizen.energystar\shared\trusted\usage.db" seems containing information about power usage with hourly timestamps ("power_usage_table" table).
 +
===iHeart Hub Radio===
 +
* The "\home\owner\apps_rw\4GKFs7KtEh\" folder contains the iHeartHub Radio app data. This app is based on Chromium and it also uses a Cache folder ("\user\home\owner\appr_rw\4GKFs7KtEh\data\chromium-elf\cache\") that can be parsed with ChromeCacheView or Hindsight.
 +
* The app seems to suggest radios based on the fridge location (Denver, Colorado).
 +
===Media folder===
 +
*The "\home\owner\media\" folder contains user media files. The internal structure seems self explicative, even though the provided dataset only contains predefined documents and pictures.

File Format
Name Samsung Smart Fridge
Ontology

Samsung Smart Fridges with the Family Hub software are smart fridges that run Tizen. A dataset shared by VTO labs has an image of all of the partitions like the system and data partition. The blog ZENA forensics has analyzed the dataset for evidence. (Just like a historian, EVERYTHING counts for a case to be solved)

Contents

[edit] Storage format

They use a GPT partitioning schema and it has a total of 21 partitions.

  • Partition 19 and 18 contain System data.
  • Partition 20 has settings by the user.
  • Partition 21 has user data.

[edit] RootFS Partition

  • \etc\os.release contains details about the installed OS. In the file we see the installed os is Tizen 3.0.
  • \etc\tizen-build.conf contains more OS info including build date.
  • The "\usr\apps" folder contains the pre-installed applications. This is archivist gold because it has apps.

All apps have a bundle name or a sort-of 10 characters-long GUID.

[edit] System-data partition

This partition has settings.

  • The "\etc\localtime" file contains information about the timezone set on the device (in the provided dataset America/Denver, where VTO Labs is located)
  • The "\dnsmasq.leases" file contains information about leases by the DNSmasq service. The provided dataset contains the following values:
    • 1517956504, that translates to 6th February 2018 at 10:35:04 UTC
    • 4c:66:41:5c:7e:92, a MAC address manufactured by Samsung Electro-Mechanics
    • 192.168.7.61, a local IP address
    • Samsung-SM-G930V, a smartphone model
    • 01:4c:66:41:5c:7e:92, a MAC address by an unknown manufacturer
  • The "\dbspace\5001\.account.db" file contains information about the Samsung account, including username and email address (in the provided dataset "connectedkitchenvto@gmail.com")
  • The "\dbspace\.notification.db" file contains notification settings (per app).
  • The "\dbspace\.alarmmgr.db" file contains alarm settings (per app).
  • The "\var\lib\bluetooth\" folder contains a subfolder apparently named as the Bluetooth MAC Address of the device. In the provided dataset the folder name is 70:2C:1F:41:E2:43, which is a Bluetooth MAC Address manufactured by Wisol, a Samsung company.
  • The "\var\lib\bluetooth\<BT_MAC>\settings" file contains the device Bluetooth name (in the provided dataset "[Refrigerator] Samsung").
  • The "\var\lib\bluetooth\<BT_MAC>\cache" folder contains various files, named as a Mac Address. In the provided dataset 6 files are stored in the folder. Every file contains a device name. They seem to be "seen" devices, although more testing is needed.
  • The "\var\lib\buxton2\system.db" contains information about OS settings. The database needs more research to understand the exact content, but it apparently contains interesting configuration and information embedded in BLOB data. Here follow the full settings list.

In the provided dataset you can find a single in entry in the "tabs" table, as shown in picture: it includes an URL (https://m.youtube.com/watch?v=bMjVvg8jOO4) and a creation date value (2018-02-07 18:18:30).
  • The "\user\home\owner\apps_rw\org.tizen.browser\data\chromium-elf\cache" folder contains browser cache items. As the Tizen Browser is based on Chromium, the Cache can be parsed with ChromeCacheView or Hindsight.

[edit] Glympse Family Map

  • The Glympse Family Map is a location-sharing service "which allows users to seamlessly share their location using a variety of devices within the Tizen ecosystem".
  • This app is based on Chromium and it also uses a Cache folder ("\user\home\owner\appr_rw\gfamilymap\data\chromium-elf\cache\") that can be parsed with ChromeCacheView or Hindsight.
  • By analyzing the images stored in the cache folder I was able to find some Google Maps images geolocated at the VTO Labs headquarter, where probably the fridge was used and then acquired.
  • Some logs files about the Glympse service are stored in the "\user\home\owner\appr_rw\com.glympse.tizen.frapp.service\data\glympse". They seem to contain information about sync with the Glympse service, but more research and testing is needed.

[edit] Samsung Connect

  • The "\user\home\owner\apps_rw\com.samsung.samsung-connect" folder contains Samsung Connect App data. This app "provides users a simple, unified way to control and monitor smart devices in one app".
  • The "\user\home\owner\apps_rw\com.samsung.samsung-connect\shared\data\sc.db" file contains references to other devices: in the provided dataset a "SAMSUNG SM-G930V" and a "Pixel 2" (table "device_table").

[edit] Energystar

  • The "\user\home\owner\apps_rw\org.tizen.energystar" folder contains energy information. The "\user\home\owner\apps_rw\org.tizen.energystar\shared\trusted\usage.db" seems containing information about power usage with hourly timestamps ("power_usage_table" table).

[edit] iHeart Hub Radio

  • The "\home\owner\apps_rw\4GKFs7KtEh\" folder contains the iHeartHub Radio app data. This app is based on Chromium and it also uses a Cache folder ("\user\home\owner\appr_rw\4GKFs7KtEh\data\chromium-elf\cache\") that can be parsed with ChromeCacheView or Hindsight.
  • The app seems to suggest radios based on the fridge location (Denver, Colorado).

[edit] Media folder

  • The "\home\owner\media\" folder contains user media files. The internal structure seems self explicative, even though the provided dataset only contains predefined documents and pictures.
