Graykey is a forensic tool designed to unlock mobile devices and extract data, primarily used by law enforcement agencies and digital forensics experts. Developed by the secretive company Grayshift — now owned by Magnet Forensics — Graykey has earned a reputation for its ability to bypass smartphone security measures.

However, a leak of some Grayshift's internal documents was recently reported on by 404 Media. According to the data, Graykey can perform partial data retrieval from iPhones running iOS 18 and iOS 18.0.1. But does not seem to have any issues with earlier versions.

A partial extraction includes unencrypted files and metadata, such as folder structures and file sizes.

Graykey's performance with Android phones is far less successful. On Google's Pixel lineup, Graykey can only partially access data from the latest Pixel 9 when in an "After First Unlock" (AFU) state — where the phone has been unlocked at least once since being powered on.
