The term "Троянскому коню" (Trojan Horse) refers to a deceptive tactic used during the Trojan War. According to Greek mythology, the Greeks constructed a large wooden horse and hid soldiers inside it, presenting it as a gift to the city of Troy. The Trojans, believing they had won, brought the horse into their city. At night, the hidden soldiers emerged, opened the city gates for the rest of the Greek army, and ultimately led to the fall of Troy. This story symbolizes the concept of deception, where an outwardly harmless object conceals a dangerous intent.
