In the chain of trust boot sequence, if we compromise one link, we can fully control all the links that follow. To load our custom Ramdisk, we have to bypass all these signature checks. Signature checks implemented at various stages in the boot sequence do not allow us to load our custom Ramdisk. In Forensics, we will create a custom Ramdisk with our complete forensic tool kit and load it into the iPhone’s volatile memory. Boot loader signature checks the kernel, and the kernel signature checks the Ramdisk.ĭuring iOS update, the Ramdisk gets loaded into RAM and it loads all the other OS components. BootRom signature checks the second level boot loaders (iBSS, iBEC). In DFU mode, iPhone follows the boot sequence with a series of signature checks as shown below. iBoot signature checks the kernel and device tree, while the kernel signature checks all the user applications. LLB signature checks and loads the stage 2 boot loader (iBoot). In Normal mode, BootRom start off some initialization stuff and loads the low level boot loader (LLB) by verifying its signature. IPhone operates in 3 modes – Normal Mode, Recovery Mode, DFU mode BootRom contains all the root certificates to signature check the next stage. The BootRom is Read-only memory (ROM) and it is the first stage of booting an iOS device.

When an iPhone boots up, it walks through a chain of trust, which is a series of RSA signature checks among the software components in a specific order as shown below: ipsw extension) that contains boot loaders, kernel, system software, shared libraries & built in applications. iOS (previously known as iPhone OS) is the operating system that runs on all Apple devices like iPhone, iPod, Apple TV and iPad. In order to create and load the forensic toolkit, first we need to understand iPhone functions at the operating system level. The problem here is: the iPhone only loads firmware designed by Apple.

As the iPhone has only one serial port, we are going to load custom OS over the USB to access the hard disk of the device. To perform iPhone forensics, we use the Live CD approach. So it is not easy to take out the chips (hard disk) and dump data into it. When we compare computers to the iPhone, it is an embedded device.

Imagine a computer which is protected with an OS level password – we can still access the hard disk data by booting a live CD, or by removing the hard disk and connecting it to another machine. Creating & Loading the forensic toolkit.Bypassing the iPhone passcode restrictions.Establishing a communication between the device and the computer.Creating & Loading a forensic toolkit on to the device without damaging the evidence.Steps involved in iPhone forensics include: The details shown below outline their research and give an overview on the usage of iPhone forensic tools.
Researchers at Sogeti Labs have released open source forensic tools (with the support of iOS 5) to recover low level data from the iPhone. GOAL Extracting data and artifacts from iPhone without altering the information on the device IPhone 4 GSM model with iOS 5 is used for forensics.
