Certified Ethical Hacker (CEH v13) — Question 226

Robert, a professional hacker, is attempting to execute a fault injection attack on a target IoT device. In this process, he injects faults into the power supply that can be used for remote execution, also causing the skipping of key instructions. He also injects faults into the clock network used for delivering a synchronized signal across the chip.

Which of the following types of fault injection attack is performed by Robert in the above scenario?

Answer options

• A. Frequency/voltage tampering
• B. Optical, electromagnetic fault injection (EMFI)
• C. Temperature attack
• D. Power/clock/reset glitching

Correct answer: D

Explanation

The correct answer is D, as Robert's actions involve manipulating the power and clock signals, which are characteristic of power/clock/reset glitching attacks. Options A and C refer to different methods of fault injection that do not match the specifics of the attack described. Option B relates to a different type of fault injection that does not apply to the scenario presented.
