Chicago O'Hare International Airport

Profile narrative

Chicago O'Hare International Airport and Chicago Midway International Airport function as major aviation hubs that provide passenger and air cargo services for domestic and international flights. They operate extensive airfield infrastructure including runways, taxiways, and aprons that support aircraft takeoff, landing, and ground movement. Terminal facilities at each airport accommodate ticketing, security screening, baggage handling, and a range of passenger amenities such as retail outlets and dining options. Both airports maintain air traffic control surfaces and ground support equipment necessary for safe and efficient aircraft movement on the ground. They also offer flight information to the public through official websites that display real‑time data on arrivals, departures, wait times, and terminal congestion. These websites serve as a primary channel for travelers and visitors to access operational updates without needing to be on site.

A distinguishing attribute of the organisation is its reliance on publicly accessible digital platforms to communicate flight status and airport conditions to the traveling public. In October 2022, the airports’ websites were targeted by a distributed denial‑of‑service attack carried out by the pro‑Russian hacker group Killnet, which temporarily disrupted access to flight information portals. Despite the interruption to the public‑facing sites, cybersecurity assessments confirmed that internal systems, air traffic control, security operations, and actual flight schedules remained unaffected. The incident highlighted the airports’ ability to isolate critical operational networks from external web services, preserving core aviation functions even when outward‑facing channels experience downtime. The attack was attributed to sources within Russia, although no direct evidence of state involvement was identified by investigating agencies. This episode underscores the importance of robust cyber‑defence measures for public information systems while demonstrating the resilience of the underlying aviation infrastructure.
