Certified Ethical Hacker (CEH v12) — Question 63

Which IOS jailbreaking technique patches the kernel during the device boot so that it becomes jailbroken after each successive reboot?

Answer options

• A. Tethered jailbreaking
• B. Semi-untethered jailbreaking
• C. Semi-tethered jailbreaking
• D. Untethered jailbreaking

Correct answer: D

Explanation

The correct answer is D, as untethered jailbreaking permanently modifies the kernel, allowing the device to stay jailbroken through reboots. In contrast, tethered and semi-tethered methods require a computer to reapply the jailbreak after each reboot, while semi-untethered can operate without a computer but still require reactivation of the jailbreak after a restart.
