Emerging threats are characterized by their use ofnew techniques and zero-day vulnerabilitiesto spread and evade detection. Unlike traditional threats, which are often recognized by existing definitions or known behaviors, emerging threats can exploit unknown weaknesses and use sophisticated methods to bypass defenses.

Emerging vs. Traditional Threats:

Traditional threats typically rely on older, well-documented attack methods, while emerging threats innovate with new propagation techniques or by exploiting recently discovered (or undisclosed) vulnerabilities.

These zero-day vulnerabilities are especially challenging because they are unknown to software vendors and antivirus programs, making detection difficult until patches or signatures are developed.

Why Other Options Are Less Accurate:

Although emerging threats may be more sophisticated (Option A) or undetectable by signatures (Option C), the defining characteristic is their reliance onnew methods and zero-day exploits.

Option B (requiring artificial intelligence for detection) is not strictly true; while AI can aid in detection, other advanced methods are also used.
