ADB Backup APK Injection

ADB Backup APK Injection
Posted Jul 10, 2015
Authored by Imre Rad

The Android ABD utility backup manager, which invokes the custom BackupAgent, does not filter the data stream returned by the applications. While a BackupAgent is being executed during the backup process, it is able to inject additional applications (APKs) into the backup archive without the user's consent. The BackupAgent needs no Android permissions. Upon restoration of the backup archive, the system installs the injected, additional application (since it is part of the backup archive and the system believes it is authentic) with escalated privileges. Proof of concept code included.
