ANDROID LOCAL STORAGE CHECKS

The user password can be found unencrypted in the following file on the device:


Copy

/data/data/com.my.application/shared_prefs/users.xml

<string name="myAPP_password">]-&xwhjgmd)u3</string>

Although files under /data/data/[app_package_name] are typically only accessible
by the app, the contents of that directory can be read by the following methods:

   

 * rooting the device

   
   

 * connecting the phone to a computer and initiating a backup with adb backup
   -noapk com.my.app, then analysing the backup contents

   
   

 * running a shell in the context of the package and copying the file to an
   uprotected directory, by issuing the command adb exec-out run-as com.my.app
   cat shared_prefs/users.xml /sdcard

   

REMEDIATION:

Where possible, passwords should not be stored on the device. Instead, perform
initial authentication with the username and password and store a short-lived,
service-specific authorization token. Alternatively, credentials can be stored
in Android's AccountManager.

If storing secrets such as a password is a requirement, use the Android Keystore
API to generate a random key when the app runs for the first time and use that
key to encrypt secrets with a block cipher such as AES before storing them in
Preferences.
