GrayKey

What is GrayKey?

GrayKeyA dedicated hardware-and-software appliance from Grayshift (now Magnet Forensics) used by law enforcement to unlock and extract data from locked iOS and Android devices.


GrayKey is a forensic device created by Grayshift, acquired by Magnet Forensics in 2023. The box connects to a seized iPhone or Android phone over Lightning, USB-C or Type-A and runs exploit chains plus passcode-brute-force logic to obtain a full file-system or partial extraction. After unlock, GrayKey produces a structured evidence package that can be parsed in Magnet AXIOM, Cellebrite or open-source tools. The product is sold strictly to vetted government and law-enforcement customers, with on-premise and Edition (offline) variants. Its existence has driven Apple's lockdown features (USB Restricted Mode, Stolen Device Protection) and ongoing privacy debate.
