New ‘Unpatchable’ iOS Exploit Could Allow for a Permanent Jailbreak for iPhone
With every new iOS release, the jailbreak community picks up some heat. Now, a security researcher has released an exploit which could allow for a permanent jailbreak for iPhone. The exploit is claimed to be a “permanent unpatchable bootrom exploit” oriented towards the iPhone 4s to the iPhone X. If the news entices you, let's dive in to see some more details on the matter.
New Exploit Could Potentially Lead to a Permanent Jailbreak for iPhone
As we have mentioned earlier, a Twitter user axi0mX has shared an iPhone exploit today by the name of "checkm8". The exploit can potentially be used to permanently jailbreak an iPhone. The public bootrom exploit will work on all device starting from the iPhone 4s to the iPhone X irrespective of whichever iOS version they are running.
The surprising element of the exploit is that Apple cannot patch it by rolling out another iOS release. In addition to this, it will give the device permission to downgrade even though Apple stops signing iOS builds. This is one of the biggest elements that the exploit will carry which users could put to use. Here's how axi0mX explains it:
What I am releasing today is not a full jailbreak with Cydia, just an exploit. Researchers and developers can use it to dump SecureROM, decrypt keybags with AES engine, and demote the device to enable JTAG. You still need additional hardware and software to use JTAG.
As of now, there is no jailbreak released today and axi0mX has released the exploit to the public for free. This makes room for the developers to do what they are good at - creating a tethered jailbreak for iPhone. What this means is that, much like Unc0ver jailbreak for iOS, users would have to jailbreak their devices again after it has been rebooted. In addition, the exploit also requires the iPhone or iPad to be connected to a PC over USB. This means that remote execution is not possible.
EPIC JAILBREAK: Introducing checkm8 (read "checkmate"), a permanent unpatchable bootrom exploit for hundreds of millions of iOS devices.
Most generations of iPhones and iPads are vulnerable: from iPhone 4S (A5 chip) to iPhone 8 and iPhone X (A11 chip). https://t.co/dQJtXb78sG
