iOS Backups: Leftover Passwords
November 10th, 2022 by Oleg Afonin
In Apple ecosystem, logical acquisition is the most convenient and the most compatible extraction method, with local backups being a major contributor. Password-protected backups contain significantly more information than unencrypted backups, which is why many forensic tools including iOS Forensic Toolkit automatically apply a temporary backup password before creating a backup. If a temporary password is not removed after the extraction, subsequent extraction attempts, especially made with a different tool, will produce encrypted backups protected with an effectively unknown password. In this article we’ll talk about why this happens and how to deal with it.
