Certified Ethical Hacker (CEH v13) — Question 55

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, Untethered jailbreaking, as this technique modifies the kernel during the boot process, allowing the device to stay jailbroken after reboots. In contrast, A (Tethered) requires a computer to reapply the jailbreak each time, B (Semi-untethered) requires a reapplication of the jailbreak after a reboot but can be done on-device, and C (Semi-tethered) allows some functionality without reapplying the jailbreak, but does not provide full jailbreak status after a reboot.
