This in turn requires an active internet connection, placing the device at risk of unwanted synchronization and/or remote lock or remote erase. If you use a regular, non-developer account, you will need to validate the agent’s signing certificate on the device before you can launch the app. A developer account is strongly recommended. You will be prompted for Apple ID credentials (login, password, and one-time code for passing two-factor authentication). Install the extraction agent by running the following command on the computer. On the iPhone: confirm pairing request and enter screen lock password when prompted. If for any reason no pairing is established, run the following command. Confirm the pairing prompt and type the screen lock passcode on the device. The pairing prompt is usually displayed automatically when you connect the iPhone to the computer. Pair the iPhone to the computer before sideloading the extraction agent. If you use a regular, non-developer account, you will need to validate the agent’s signing certificate on the iPhone, which requires an active internet connection and brings the associated security risks We strongly recommend using an Apple ID account enrolled in Apple Developer Program. Sideloading the extraction agent requires an Apple ID login and password. When installing the extraction agent, the iPhone must be unlocked and paired to the computer. Note: if a previous version of the extraction agent is already installed, remove it from the device as you would uninstall any other app. The extraction agent is an iOS app that must be sideloaded (installed) onto the iOS device. EIFT_cmd agent uninstallĪlternatively, you may uninstall the extraction agent from the device by long-pressing its icon and deleting the app. On the computer (uninstall the extraction agent). EIFT_cmd agent tar –system -o system.tar “all exploits failed”), restart the iPhone. (Note: this requires an active internet connection and carries certain security risks). On the iPhone: if you are using a non-developer Apple ID to sideload the agent, validate the signing certificate on the iPhone. Sideload the extraction agent onto the device by running the following command. If the device was not automatically paired, you will need to manually pair the device to the computer by running the following command. On the device, confirm the pairing prompt and enter the screen lock passcode. Once the iPhone is connected to the computer, you will be prompted to establish trust between the device and the computer. On the computer, launch iOS Forensic Toolkit. Note: we recommend using a USB 3.0 port to speed up the extraction of certain devices. Once the extraction agent is uninstalled, the only traces left on the device are several records representing agent-related events in the device’s diagnostic logs. While the process is not fully forensically sound, the modifications made to the data are minimal. The app establishes a communication channel between the device and the computer, escalates privileges, and gains access to the file and the encryption keys required to decrypt the content of the keychain.Īgent-based low-level extractions deliver the cleanest experience for newer devices without checkm8 support. The extraction agent is an app sideloaded to the iPhone being extracted. For newer models starting with iPhone Xr/Xs, using the extraction agent is the only way to extract the file system and decrypt the keychain. This is why low-level extraction almost never comes to the current, up-to-date and fully patched versions of iOS. This method is highly dependent on kernel exploits, which are extremely difficult to implement. To deliver low-level extraction for newer iPhones and iPads, we developed an in-house extraction agent that comes as close to being forensically sound as possible. checkm8 extractions are great, but they aren’t compatible with newer devices. For older hardware, the checkm8 extraction delivers the cleanest results our solution is unrivaled in providing truly forensically sound extractions for all compatible devices, which include a number of iPhone, iPad, Apple Watch and Apple TV devices. Low-level extraction can be done differently. In this quick-start guide we will lay out the steps required to extract the file system and decrypt the keychain of a compatible iPhone or iPad device. While this approach offers experts full control over the extraction process, mastering the right workflow may become a challenge for those unfamiliar with command-line tools. IOS Forensic Toolkit 8 brings new powerful user experience based on the command line.
