Certified Ethical Hacker (CEH v12) — Question 293

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, Power/clock/reset glitching, as Robert is specifically injecting faults into the power supply and clock network. Options A, B, and C refer to different types of fault injection techniques that do not involve the specific manipulation of power and clock signals as described in the scenario.
