Certified Ethical Hacker (CEH v11) — Question 389

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 is directly manipulating the power and clock signals, which is characteristic of power/clock/reset glitching attacks. Options A and C do not accurately describe the techniques being used in this scenario, while B refers to a different method of fault injection that does not involve the power supply or clock network.
