The Chinese word **木马** (mùmǎ) is a compound noun formed by combining the characters **木** (mù), meaning "wood," and **马** (mǎ), meaning "horse," to create the literal meaning "wooden horse." This term directly references the ancient story of the **Trojan Horse**, a wooden structure used by the Greeks to infiltrate Troy. Through metaphorical extension, this historical concept has been applied to modern technology, where it now commonly refers to a **"Trojan horse" or "Trojan"** in cybersecurity—a type of malicious software that disguises itself as legitimate to breach a system's defenses, perfectly mirroring the deceptive function of its mythological namesake.
