Once the jailbreak is installed, start iOS Forensic Toolkit. You can now perform the file system acquisition, exactly the same way you do it with all other jailbreaks. Important: when prompted for the port number, enter 44 instead of the standard The new port number is basically the only difference except for the root password routine.
If the root password was changed, you can still type it manually. There is another important point: if the screen lock passcode is unknown, options D Disable lock and K Keychain will not be available throw an error , and only F File system works. To obtain the complete file system and the keychain , you need to unlock the device, and keep it unlocked during the acquisition. The acquisition itself is as simple as that; you will spend most of the time installing the jailbreak of which getting the device into DFU takes the most effort and analyzing the results.
With this new jailbreak, can you extract the file system without EIFT or similar software? Technically, you can obtain a copy of the file system. First things first: this jailbreak cannot help with passcode recovery. As we already noted, some limited data can be obtained from locked devices.
It does not create a serious security risk as the device itself still remains locked. With the new jailbreak, all such files are accessible prior to unlocking. Just to name some:. No passwords there, yet you can access some information about the device owner and all related accounts used on this device. The best results, however, can be achieved only if the device is unlocked the screen lock passcode is not set or is known.
Do not overlook the keychain decryption; you will gain access to tons of passwords and authentication tokens, opening the door for cloud acquisition with Elcomsoft Phone Breaker for Apple iCloud and Elcomsoft Cloud eXplorer for Google accounts. If you need to analyse a file system image. We strongly recommend reading these two articles in order to understand and avoid potential issues such as the computer connecting to the wrong iOS device.
Most importantly not just for this jailbreak, but in general : before acquisition, disable all Wi-Fi and Ethernet! There is one minor issue with keychain extraction occurring in the Windows edition only. You will get the following prompt after selecting the iOS version :. With the second option, the Toolkit sends a command to unlock the keychain to receive all the data , and the iPhone shows a prompt to enter the passcode.
If you are familiar with USB restricted mode , you may ask whether it affects the ability to jailbreak with checkra1n and acquire with iOS Forensic Toolkit. The answer is yes, it does. In DFU mode, the device is still accessible even if DFU restricted mode has been activated; checkra1n can be installed and no passcode is needed.
Once the jailbreak is installed, partial BFU acquisition is possible, and it is worth going after. Double click on it. Here you can see the "Documents" folder and the photos you saved earlier. You can't delete photo from this list. Because this is the iPhone device section, you accessing through the xcode.
If you want to delete the photos, you have to delete the whole project. To do that, scroll down below the screen and there should be a minus "-" button. After selecting your project just click on it. It will delete your photos as well as whole project. And then on the simulator the folder is found on your mac and the file path is as Vin and Osiris has given. Also note that you have to plugin the device in order to access the copied files Programmatically.

So, there is less risk of distortion of evidence data. Hence we use the method to exploit the BootROM vulnerability and patching stages as shown in the figure below. Forensic tools leverage this vulnerability to perform physical acquisition of iOS devices.
This tool instructs the examiner to switch the device into DFU mode. Once the device is placed in the DFU mode, the tool will verify and provide an alert indicating that it is possible to perform physical acquisition using this method for this device or of the need to perform another method of acquisition.
Once we proceed with the physical acquisition, the tool will start uploading Bootloader to iPhone. It prompts the screen to extract system data or user data.
If the connected phone is not jailbroken, then the system partition would be in read-only mode. As shown in the figure below, to acquire a full image, both data and system partition need to be selected.
Most of the tools dump data and system partition as a single disk image. The selected tool dumps the image to a destination folder as shown below:. This covers a method to Jailbreak IOS device 9. Using this method user could gain access to all partitions including the file system with read-write. This method is not accepted forensically because it may overwrite some important data but it allows performing physical acquisition efficiently.
Jailbreak is a method to remove software restrictions and expand the feature set by a manufacturer like Apple in the case of IOS. This method is used when root access of the file system is required as well as for the physical acquisition. Steps are described below,.
The figure above shows the notice presented by the application. This warns the user about Data loss may occur as well as for the smoother and successive operation suggests switching the phone to airplane mode.
It also suggests backing up data before proceeding further. The output of all the mentioned tools would either be a bitstream image dd or a DMG image file that can then be analyzed manually or with the help of a forensic analysis tool. It also supports the extraction of secret passwords and decryption of file systems.
This process takes time depending on the amount of user data. Upon finishing, the data extracts the. The figure below shows this process. Using option 6, the User can acquire a physical image of the device file system.
The tool would prompt to select the option to choose whether to extract system and user data. Please refer to the screenshot below, in which option 2 has been chosen. Encrypted user data will then be extracted. To decrypt this data, we can use keys. This section covers the analysis of the important artifacts that are generated by features of the system or interaction of the user with the device.
While analyzing artifacts, it is important to determine the timestamp of that artifact. There are resources available that can convert this timestamp to human-readable time. This is also performed using the date command with u switch on Mac, which will display time in UTC or on local time.
These databases are used to store data of native as well as third- party applications. These files stores configuration information, preferences, and settings. These files could be explored using a simple text editor. A tool commonly used to parse these files is plist Editor. Information extracted from the configuration or preferences files could be important which investigation.
Some important configuration files are listed below. IOS devices are provided with some pre-installed applications like Safari browser, e-mail client, calendar and basic phone function utilities like Camera, Call history. These artifacts can be found in the application folder itself. Data related to the communication, preferences, Internet history and cache, keyboard keystrokes can be found from the Library folder,. Contacts, Application related to personal contacts in SQLite database file format are available in Library folder of AddressBook folder.
Two important databases are available in this folder one is AddressBook. This information is saved in tables. These images appear on the screen when that contact calls. A preinstalled app like Voice memo allows the user to record voice memos. In folder mentioned above file named Recordings.
Information like date, duration, memo name and filename of an audio file could be extracted from this database file. Manually events can be created within the calendar as well as it syncs events with other applications.
This information is stored in two database files. It also provides the date, time, and duration of the call. DialerSavedNumber — Last dialed phone can be extracted from the plist file from the below location. This file remains though user deletes call history database file so forensically this is a very important file. Another important file with the forensic perspective is com.
Location for this file is as below. Each account has a separate folder within the Apple Mail application. Using Thumbnails and information about images can be recovered irrespective of the original image is available or deleted. Information related to the last searches, like search query or Longitude and Latitude coordinates can be retrieved from below path. The main folder of Maps contains information of the searches of users and bookmarked locations. It is located at path. Every IOS device has the Safari browser preinstalled.
There are two locations where all activities get stored. This file is important as a forensic perspective because when the user would delete cache or history from the browser then as well this file would not be deleted.
This plist file contained state of safari when user powered off iPhone or browser got crashed. This file would contain a list of URLs open at the time of state occurred. If history is cleared by the user then it this file would not contain history. Artifacts covered in this section are not related to any particular application, but those are the evidence generated by general use of the IOS device. Data like passwords or other portions of text data which copied, cut, or pasted by the user are stored in this file.
Auto correction and auto-completion while typing are supported by IOS devices. Device caches user types in file dynamic-text. In the same directory IOS stores, one file for each language is used and configured on the keyboard. The consolidated. In newer devices, a new database has been included instead of consolidated. The main difference is data remains only for 8 days before being cleared out. Other applications which track the geographical locations may store GPS coordinates and timestamps.
Fade-out effect is being used by IOS for the transition of two screens. As a part of this IOS saves screenshots of the current screen and fade out effect applied picture of the current screen. Using these feature lots of forensically valuable information can be gathered. This feature is to assist the user to assist while searching like applications, SMS, contacts and more. In the directory mentioned above, there are two folders related to SMS searches and another of general spotlight utility.
Two types of wallpaper images are available. This section covers third-party application analysis which includes locations of the important artifacts related to third party applications.
The above screenshot shows only the username which last logged on. This folder contains one folder for each account logged in with that device as shown in below figure below. Each user folder has the database which contains information like chats, contacts. There are utilities available which parse these files. In the application folder voicemail messages, screenshots can be found.
This plist configuration file provides basic information like username, phone number to which WhatsApp account is associated and more. It is most widely used social network application. Because of this, during the investigation, high amount of information from the Facebook application can be found. Mainly three kinds of information can be found — user personal information, caches of visited profiles and pages, information about external sites visited within the Facebook application.
Email address and Facebook id of configured account on the application could be extracted from this file. The date of the last time application was also used could be retrieved from this file. As the cloud allows the accessing of stored data from anywhere and anytime, Cloud storage applications have become very popular. It is very frequent that this kind of application would be encountered during the investigation.
Analysis of few popular cloud storage applications is covered in this section. Local copies of opened files are saved on Cache folder. It could acquire only through physical acquisition. A file named com. This plist file contains user information like name, surname, and email. The application structure is shown in the screenshot below:.
There are two subfolders within it. Documents and Library. In Library another subfolders Caches, preferences, and Cookies. User information like name and surname, User ID and User e-mail can be found from plist file com. Cached copies of opened files are stored in Caches. It could be extracted if the dump is acquired using Physical acquisition. All information listed below about files stored is in Items db.
