The paper highlights risks that accompany losing a locked iOS device regarding confidentiality of passwords stored in the keychain. It presents results of hands-on tests that show the possibility for attackers to reveal some of the keychain entries. For the described approach, the knowledge of the users secret passcode is not needed, as the protection provided by the passcode is bypassed.
