Apple has reportedly found a way to prevent GrayShift's GrayKey police investigative tool from opening iPhone in legal law investigations.
Multiple sources familiar with the GrayKey tech have told Forbes the device can no longer break the passcodes of any iPhone running iOS 12 or above. On those devices, GrayKey can only do what’s called a “partial extraction,” sources from the forensic community said. That means police using the tool can only draw out unencrypted files and some metadata, such as file sizes and folder structures.
