About this MCQ
This Medium Cyber Security MCQ checks one syllabus fact.
The question is: “Select the correct name for: malware that encrypts a victim's files and demands payment for the decryption key.”
The accepted answer is B. Ransomware. “Select the correct name for: malware that encrypts a victim's files and demands payment for the decryption key.” is answered by Ransomware (option B). Option A (“Phishing”) does not match the stem; it is a near-miss used to catch incomplete recall of Ransomware. Option C (“Public key cryptography”) does not match the stem; it is a near-miss used to catch incomplete recall of Ransomware. Remaining alternatives (Denial-of-Service (DoS) attack) fall outside the same rule and should be eliminated once Ransomware is identified. Cyber Security questions of this type reward precise definitions rather than approximate associations. Cyber Security recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
