A new iPhone exploit has been discovered that could be used for permanent jailbreaking and it apparently affects a wide range of Apple devices.
According to a recent report, this new exploit affects devices from the iPhone 4S to the iPhone X. It is called checkm8, and apparently, this is an exploit which Apple would be unable to patch in the future.
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

Understanding the Checkm8 Exploit
This new exploit is apparently a bootrom exploit, which means it takes advantage of code that iOS uses when it boots up. Bootrom exploits are particularly significant because they target the read-only memory (ROM) of the device, which contains the initial code that runs when the device is powered on. This code is immutable, meaning it cannot be altered or patched by software updates, making the exploit permanent.
The checkm8 exploit is unique because it affects a wide range of devices, from the iPhone 4S to the iPhone X, covering multiple generations of iPhones and iPads. This broad impact is due to the fact that the vulnerability lies in the hardware itself, specifically in the bootrom, which is consistent across these devices.
Implications of the Checkm8 Exploit
The discovery of the checkm8 exploit has significant implications for both users and Apple. For users, this exploit opens the door to permanent jailbreaking, allowing them to gain full control over their devices. Jailbreaking can enable users to install unauthorized apps, customize the user interface, and access system files that are normally restricted. However, it also comes with risks, such as increased vulnerability to malware and voiding the device’s warranty.
For Apple, the checkm8 exploit represents a major security challenge. Since the vulnerability is in the hardware, it cannot be patched through software updates. This means that all affected devices will remain vulnerable for their entire lifespan. Apple may need to focus on securing future devices to prevent similar exploits from occurring.
As yet, there is no official word from Apple about this exploit that has been discovered on Apple’s iPhone. The company is likely investigating the issue and may provide guidance or mitigation strategies for affected users. In the meantime, users should be cautious about jailbreaking their devices and consider the potential risks involved.
The checkm8 exploit has also sparked discussions within the security community. Some experts view it as a significant breakthrough for the jailbreaking community, while others are concerned about the potential security risks. The exploit has been made publicly available, which means that anyone with the technical know-how can use it to jailbreak their device. This could lead to an increase in jailbroken devices and potentially more security incidents.
The checkm8 exploit is a groundbreaking discovery that affects a wide range of Apple devices. It highlights the importance of hardware security and the challenges of addressing vulnerabilities in read-only memory. While it offers new possibilities for users who want to jailbreak their devices, it also poses significant risks and challenges for both users and Apple. As the situation develops, it will be interesting to see how Apple and the security community respond to this unprecedented exploit.
