CertNexus Certified Cyber Secure Coder (CSC) — Question 97

A suspicious script was found on a sensitive research system. Subsequent analysis determined that proprietary data would have been deleted from both the local server and backup media immediately following a specific administrator’s removal from an employee list that is refreshed each evening. Which of the following BEST describes this scenario?

Answer options

• A. Backdoor
• B. Rootkit
• C. Time bomb
• D. Logic bomb

Correct answer: A

Explanation

The correct answer is A, Backdoor, because it indicates unauthorized access that allows actions to be executed without detection. The other options do not fit as well; a Rootkit is primarily for hiding processes, a Time bomb is triggered at a specific time, and a Logic bomb is activated by a specific condition, but does not necessarily involve unauthorized access like a Backdoor.
