hijacker

A hijacker is someone who illegally takes control of a vehicle, shipment, or process, typically using threats or force to demand money, political concessions, or a change in destination. While the "Golden Age" of air travel unfortunately brought aircraft hijacking (or "skyjacking") into the global spotlight—leading to the rigorous airport security measures we see today—the term's reach is much broader.

The most dramatic examples involve aircraft hijacking, where individuals seize control mid-flight, often holding passengers hostage. However, "hijacking" also describes highway thieves who intercept trucks to steal cargo. In the modern era, the word has migrated into the digital and social spheres. In computing, "session hijacking" occurs when a hacker takes control of your active online session to steal data. Socially, we often say someone "hijacked the meeting" or "hijacked the conversation" when they forcefully steer the discussion away from its original purpose to serve their own agenda.

Regardless of the setting—whether it's a plane in the sky, a truck on the highway, or a digital account—a hijacker is defined by the forceful and unlawful takeover of something in progress, leaving disruption and fear in their wake.
