The instrument is designed for cops.

According to VICE’s Motherboard, the Internet-connected $15,000 instrument makes use of an undisclosed iPhone jailbreak or zero-day exploit which shall we it destroy password access throttling enforced by means of the Apple-designed Secure Enclave cryptographic coprocessor.

After 4 consecutive passcode makes an attempt, the Secure Enclave starts delaying additional makes an attempt, by means of one minute for a 5th unsuccessful strive or one hour for the 9th consecutive passcode error.
