CompTIA CySA+ (CS0-002) — Question 28

Which of the following threat classifications would MOST likely use polymorphic code?

Answer options

• A. Known threat
• B. Zero-day threat
• C. Unknown threat
• D. Advanced persistent threat

Correct answer: A

Explanation

The correct answer is A, as known threats often utilize polymorphic code to evade detection by antivirus programs. Zero-day threats (B) are newly discovered vulnerabilities and may not specifically use polymorphic code. Unknown threats (C) are not identified, making them less likely to fit this classification, and advanced persistent threats (D) typically employ a variety of techniques, but polymorphic code is more characteristic of known threats.
