iOS 13 (Beta) Forensics

Thursday, July 25th, 2019

iOS 13 is on the way. While the new mobile OS is still in beta, so far we have not discovered many revolutionary changes in the security department. At the same time, there are quite a few things forensic specialists will need to know about the new iteration of Apple’s mobile operating system. In this article, we’ll be discussing the changes and their meaning for the mobile forensics.

iCloud backups

We’ve seen several changes to iCloud backups that break third-party tools not designed with iOS 13 in mind. Rest assured we’ve updated our tools to support iOS 13 iCloud backups already. We don’t expect the backup format to change once iOS 13 is officially released, yet we keep an eye on them.

First, Apple has changed the protocol and encryption. There’s nothing major, but those changes were more than enough to effectively block all third-party tools without explicit support for iOS 13.

Second, cloud backups (at least in the current beta) now contain pretty much the same set of info as unencrypted local backups. Particularly missing from iCloud backups made with iOS 13 devices are call logs and Safari history. This information is now stored exclusively as “synchronized data”, which makes it even more important for the investigator to extract synced evidence in addition to backups. Interestingly, nothing was changed about synced data; you can still use the same tools and sign in with either Apple ID/password/2FA or authentication tokens. (more…)

iOS Call Syncing: How It Works

In our previous article, we figured that iPhone call logs are synced with iCloud. We performed multiple additional tests to try to understand exactly how it works, and are trying to guess why. (more…)

Supporting Apple iCloud Drive and Decrypting Keychains from iCloud

Thursday, March 12th, 2015

As you may already know from our official announcement, we’ve recently updated Elcomsoft Phone Breaker to support Apple accounts upgraded to iCloud Drive and decrypting keychains from iCloud. Considering that one can access files stored in iCloud Drive without any third-party tools, is the update really worth the buzz? Read along to find out!

Before getting to the updated technology, let’s have a look at what Apple iCloud Drive is, and how it’s different from “classic” iCloud. (more…)
