The decrypted data is used as a key for decrypting the sqlitecipher database. The decryption of the AKS file looks like this:ģ.

It then decrypts the file using Android KeyStore key and iv generated from the output of a custom hash function named “getMagic.” This is implemented in a shared object called “libload-strings.so,” which gets a SHA256 of a unique Android id as it inputs and outputs the iv.

It opens a file called “aks” (initials for Android KeyStore).

The application performs the following steps to get the decryption key to decrypt its database: Samsung Health has a large infrastructure for cryptographic operations on data. The background application still runs and collects data. When exiting the GUI application and killing it.

“” – A graphical application that the user can interact with.

This process collects pedometer data and handles database operations.

“.shealth:remote” – A none-graphic background process that runs all the time, even when the user is not actively interacting with the application.

How Does Samsung Health Encrypt/Decrypt Its Data?įirst, it’s important to understand how Samsung Health runs. The keys can be used for encryption and decryption operations without entering the application because the cryptographic operations are handled in the operating system with a hardware-backed system. The Android KeyStore system lets you store cryptographic keys in a safe location in order to make it difficult to collect them from the phone. It can also run on all recent Android and iOS phones. Today the app is installed by default on Samsung phones and on some models, it cannot be removed without root. The application was introduced to Samsung users on Jwith the new Samsung Galaxy S3 smartphone. Samsung Health is an application that tracks various aspects of daily life contributing to well-being such as physical activity, diet, and sleep.

Samsung Health runs in the background and stores the user’s activity even when the GUI application is not running or used by the user.

We looked for popular applications that store the user’s location. My research started when our decoding group decided to focus on finding location data in Android environments because of COVID-19. I hope that by releasing this blog the mobile forensics community will be inspired to continue to examine memory dump methodologies and spark the community to share their findings. I will present an end-to-end procedure that starts with the RAM extraction and ends with the decryption and display of Samsung Health’s databases.

The phone’s RAM stores the decryption keys for the application after collecting the relevant keys from KeyStore and manipulating them. In this blog, I will demonstrate a method to decrypt the databases and collect meaningful data using a RAM dump. As of today, no commercial tool decrypts the database of the application as Samsung uses Android’s “KeyStore” to encrypt and decrypt their data. As one might expect, the application stores a lot of interesting location data that interests the forensics community and specifically law enforcement investigators. Samsung Health is a wellness application that helps users track their physical activities.
