![]() ![]() The complete compatibility matrix now looks as follows:Ĭheckm8 does not affect the Secure Enclave. The new SEP hardening measures effectively prevent checkm8 extractions on the absolute majority of A11-based devices in circulation (the iPhone 8, 8 Plus, and iPhone X). The patch effectively blocks the exploit from accessing the data if a passcode was ever configured on the device (even if subsequently removed). Apple’s last-minute change in the release version of iOS 16 included an unexpected SEP patch that broke checkm8 extraction completely. Days before the release of the final build of iOS 16 we were ready to roll out iOS Forensic Toolkit 8 with iOS 16 support on A11 devices. The increased security measures require removing the screen lock passcode before applying the exploit on the iPhone 8, 8 Plus and iPhone X models running iOS 14 through 15.7, yet we were able to overcome this protection for the iPhone 7 and 7 Plus. In response to checkm8, Apple attempted to strengthen security of the latest vulnerable devices, the iPhone 7, 7 Plus, 8, 8 Plus and iPhone X range by hardening SEP protection. 4 AppleTVs: AppleTV3,1 AppleTV3,2 AppleTV5,3 AppleTV6,2.We support 18 different chips vulnerable to BootROM exploits, namely: We support a number of major OS releases ranging from iOS 7 through iOS 15.7 (with limited iOS 16 support) in three different flavors (iOS, tvOS, and watchOS) for three different architectures (arm64, armv7, and armv7k). Our implementation of checkm8 extraction is available for 76 Apple devices including a host of iPhone, iPad, iPod Touch, Apple Watch and Apple TV models. Linux and Windows editions are in the works. The initial release of iOS Forensic Toolkit 8.0 is available for macOS computers and can be launched on both x86 and Apple Silicon (M1/M2) computers. Compatibility, System Requirements and Limitations ![]() For that to work, during the extraction process you will need to download a matching copy of the original device firmware from Apple (the download link will be provided at the time of extraction). Our implementation works entirely in the RAM it does not boot the OS installed on the device and does not modify the data or system partition. By its very nature, the exploit does not need to modify the file system all modifications are performed on the fly in the device’s volatile memory. How did we make it possible?Ĭheckm8 is ideal when it comes to forensic extractions. As a result, there won’t be a trace left on the iPhone extracted with iOS Forensic Toolkit, not a single log entry and not even a changed timestamp. We are yet to see a purely checkm8-based solution that does not borrow from checkra1n while offering repeatable extractions several times in a raw, so we developed our own implementation built from the ground up. ![]() Multiple solutions exist, but none of them is perfect. Today, checkm8 is a common and widely accepted tool in the mobile forensic community. For 32-bit devices the exploit can even be used to unlock devices with an unknown screen lock passcode. The latest iPhone models that can be exploited include the iPhone 8, 8 Plus and iPhone X devices (up to and including iOS 15.7). Exploiting a vulnerability in the bootloader of many Apple devices including several generations of iPhones, iPads, iPod Touch, Apple Watch and even Apple TV devices, checkm8 allows breaking into a device almost regardless of the version of iOS installed on these devices. Released almost exactly three years ago, checkm8 came as a huge surprise. IOS Forensic Toolkit 8.0 is officially released! Delivering forensically sound checkm8 extraction and a new command-line driven user experience, the new release becomes the most sophisticated mobile forensic tool we’ve released to date. ![]()
