The Trojan Horse has evolved far beyond its ancient origins into a global symbol of deception and hidden threat. The 'Trojan horse' metaphor now appears in cybersecurity (malicious software disguised as harmless files), in politics (hidden agendas), and even in marine ecology (where artificial structures are called 'Trojan horses' when they disguise development as environmental benefit). The story has been repurposed across every era to name the thing that looks like a gift but is really a weapon.
