Short description: American mobile device forensics company

Grayshift is an American mobile device forensics company which makes a device named GrayKey to crack iPhones, iPads, and Android devices.

Grayshift was co-founded by David Miles, Braden Thomas, Justin Fisher and Sean Larsson.[1] The company is funded by private investors PeakEquity Partners and C&B Capital.[2][3]

GrayKey

The GrayKey product has been used by the FBI and U.S., British and Canadian local police forces.[4][5][6][7][8][9] Canadian police forces require judicial authorization (court order or warrant) per mobile phone to use GrayKey.[citation needed] GrayKey is estimated to be used in up to 30 countries.[10]

According to media reports, GrayKey costs US$15,000 to US$30,000 per copy depending on the functional options chosen.[11] One thousand agencies currently use GrayKey[12] The device is a gray box, 4 inches by 4 inches by 2 inches in size, with two Lightning cables.[13] The time to solve an iPhone's passcode can be a few minutes to several hours, depending on the length of the passcode.[citation needed] Thus, it is possible that GrayKey is performing a brute-force attack to perform to solve after disabling the passcode attempt limit.[14]

The GrayKey reportedly provides support for iPhones running iOS 9 and later.[15] Apple modified iOS so that external device connections must be authorized by the iPhone owner after it has been unlocked.[16] On newer iPhone models, only unencrypted files and some metadata might be extracted. With earlier models, full data extraction, such as decrypting encrypted files, is possible.[17][citation needed]

In 2018, hackers obtained the GrayKey source code, and attempted to extort a payment of 2 bitcoins from Grayshift after leaking "small chunks of code".[18][19]

GrayKey with Android support was released in early 2021.[20]
