This suggests the agent doesn’t demand too much from the processor when installing. “GrayKey known to install agent with 2 to 3% battery life,” the document reads, referring to the “brute force agent” GrayKey installs on the phone in order to unlock the device. The instructions describe the various conditions it claims allow a GrayKey connection: the device being turned off (known as Before First Unlock, or BFU) the phone is turned on (After First Unlock, or AFU) the device having a damaged display, and when the phone has low battery. And it can still do this even if the targeted device is on the verge of battery death. But it appears GrayKey is still capable of bypassing iOS security features, enabling investigators to brute force device passwords. Apple prides itself on providing secure devices. Joseph Cox at Motherboard has obtained more documents about Grayshift’s phone-cracking device, GrayKey. It seems to be able to find exploits faster than Apple can patch them, leading to a tech arms race that law enforcement appears to be able to win from time to time. The company has an ex-Apple security engineer on staff and has been duking it out with the device manufacturer for the past few years. Grayshift is one of the vendors selling phone-cracking tech to law enforcement agencies. ![]() Proclamations that the criminal world is “going dark” are often followed by the announcement of new exploits that give law enforcement the ability to decrypt phones and access their contents. The FBI’s narrative keeps getting interrupted by inconvenient facts. (The FBI has refused to hand over a correct count of encrypted devices in its possession for more than three years at this point.) Both of these directors relied on inflated numbers to make their case - an error chalked up to software rather than rhetorical convenience. ![]() Consecutive FBI directors ( James Comey, and Chris Wray) have declared a small scale war on encryption. ![]()
