Researcher Releases ‘Permanent Unpatchable Bootrom’ iOS Exploit Checkm8 That Could Cause Serious Problems for iPhone, iPad Hardware
An iOS security researcher who goes by axi0mX on Twitter and Github posted a new software tool called Checkm8 that he claims uses a “permanent unpatchable bootrom exploit” that could bypass boot security for millions of Apple devices, from the iPhone 4S to the iPhone X. The researchers did not release a full jailbreak, but an exploit that can be used it to dump SecureROM [the boot ROM code], decrypt keybags [the escrow memory with the keys for all encrypted data on the device] with AES engine, and demote the device to enable JTAG. It’s possible other researchers have found the exploit and are already using it, especially via tools used by intelligence and law enforcement agencies, such as GreyShift’s GreyKey.

@lilyhaynewman: today a researcher dropped a really rare type of exploit that can be used to jailbreak EIGHT generations of iPhones *and* the vuln is unfixable. so that's a thing now.
@andreabarisani: What was I saying recently about unpatchable bootrom exploits?We find them constantly in automotive grade SoCs. Consumer products have even larger attack surface...Future hacks will more and more target the code embedded in the silicon.
@campuscodi: NEW: New Checkm8 jailbreak released for all iOS devices running A5 to A11 chips-works on iPhones 4S up to iPhone 8 and X -doesn't support A12 and A13 chipsets -code available on GitHub -uses "a permanent unpatchable Bootrom exploit"https://zdnet.com/article/new-checkm8-jailbreak-released-for-all-ios-devices-running-a5-to-a11-chips/
@thomasreed: If you haven’t heard yet, an exploit was dropped on Twitter this morning capable of modifying the bootrom on nearly all iOS devices except the most recent. Learn about the possible implications here:
@dangoodin001: Good writeup for anyone trying to understand the security consequences of the Checkm8 exploit.
