JavaScript : Unsafe internal storage

The application insecurely stores sensitive information.

Async Storage - a module in React Native that provides asynchronous, unencrypted storage as a key-value pair.

Data in Async Storage is well isolated and protected from access to it from other apps. Despite this, an attacker with access to the device can get the contents of the sandbox and extract the data saved in Async Storage. It’s especially dangerous for devices with jailbreak (for iOS) and rooting (for Android).
