Apple File Conduit (AFC) Backup: AFC has access to music, all pictures and videos, and third-party app data (depending on iOS version).

iTunes Backup: Includes voicemail, voice memos, call history, SMS, iMessages, photos and videos, and third-party app data.

For mobile forensics, two extraction methodologies exist:.These tools parse the manifest.mbdbfile, restore the filenames, and create the iOS device's file structure.

If you don't have one of these tools, use a fresh install of iTunes to create a backup file for examination.These tools use iTunes to create a backup file for examination.There are several tools available to create backup files:.For example, email and passwords WILL NOT be extracted if the backup is not encrypted!.An encrypted backup gives us access to data that would otherwise be inaccessible.

An encrypted backup file that can be cracked provides us with access to MORE DATA than an unencrypted backup file!.

When extracting iOS devices it is important to keep in mind:.

Combination of Power and Home Buttons plus connection to computer with iTunes installed.

DFU mode is a method recognized in mobile device forensics and is deemed to be a forensically sound action to prepare the device for forensic acquisition.

Or.Brute Force/Dictionary Attack on Passcode.

Forensic acquisition through bootloader/ramdisk.

Kernel verifies and loads ramdiskinto memory.

iBSSis modified version of iBootthat kicks off iBEC.

Forensic tools use DFU mode to perform physical acquisitions.

DFU is a low-level diagnostic mode designed to perform firmware upgrades.

When Boot ROM can't boot into LLB, DFU Mode is initiated.

Turn Off, Hold down Home, connect via USB.

Recovery Mode is required to perform upgrades or restore the iPhone.

Can occur if one of the boot up codes fails to load or verify.

iOS Kernel -authenticates and runs user apps.

Low Level Bootloader -runs its code, verifies next stage.

Contains Apple root CA public key in order to authenticate next stage

On those devices, GrayKey can only do what's called a "partial extraction," which means the tool can only extract unencrypted files and some metadata, such as file sizes and folder structures In October 2018, multiple sources familiar with the GrayKey reportedthe device can no longer break the passcodes of any iPhone running iOS 12 or above The Secure Enclave makes it especially time-consuming to carry out brute forcing by incrementally increasing the time between guesses, up to an hour for the ninth attempt onwards It appears Grayshift has access to similarexploitsas Cellebrite, namely a probablehack that targets Apple's SecureEnclave, the isolated chip in iPhones that handles encryption keys

GrayKey claims to work on disabled iPhones and can extract the full file system from the Apple device by making repeated guesses at the passcode Grayshift appears to berun bylong-time U.S.intelligence agencycontractors and an ex-Apple security engineer In late 2017, word of a new iPhone unlockerdevice started to circulate: a device calledGrayKey, made by a company named Grayshift.īased in Atlanta, Georgia, Grayshift was founded in 2016, and is a privately-held company with fewer than 50 employees. This layer deals with low-level functionalities and provides services such as networking (BSD sockets), memory management, threading (POSIX threads), file system handling, external accessories access, and inter-process communication. ⬜The Core OS layer: The Core OS layer is the base layer and sits directly on top of the device hardware. The layer contains technologies to support features such as location, iCloud, and social media. All these services are not used by the developers though many parts of the system are built on top of them. ⬜The Core Services layer: The Core Services layer provides the fundamental system services that are required for the applications. The technologies in this layer help developers to build applications that look and sound great.

⬜The Media layer: The Media layer provides the graphics and audio and video frameworks to create the best multimedia experience available on a mobile device. Frameworks in this layer provide the basic application infrastructure and support key technologies, such as multitasking, touch-based input, and many high-level system services. ⬜The Cocoa Touch layer: The Cocoa Touch layer contains the key frameworks required to develop the visual interface for iOS applications.
