Attackers could receive for services used. Conscious Android device by exploiting the bug authentication data in the hands Hackers could, for example authentication data for payment services and banks can get hold of. However, they shall install malware on a vulnerable device: it is necessary to perform in order to exploit the bug in code yourself. It is not clear whether abuse of vulnerability in keystore.
