Ransomware and data extortion groups are increasingly targeting the aviation and aerospace sector, exploiting interconnected systems, shared platforms, and identity-based access models to cause operational disruption and data compromise.
Cyber risk across aviation has shifted beyond traditional IT incidents toward ransomware attacks, credential theft, and platform-level compromise.
The aviation ecosystem relies heavily on shared IT infrastructure, including passenger processing, baggage handling, and scheduling platforms.
The September 2025 attack on Collins Aerospace’s MUSE system demonstrated how a compromise at a single vendor can disrupt operations at major hubs such as Heathrow, Brussels, Berlin, and Dublin.
Recent disruptions reported across European airports in April 2026, combined with the confirmed 2025 ransomware attack on Collins Aerospace’s MUSE passenger-processing platform, highlight how a single cyber event can cascade across multiple airports and airline operations.
Airports were forced to shift to manual processing, causing delays and operational bottlenecks.Similar disruption was reported between April 4 and April 6, 2026, affecting several European airports.
While technical attribution remains unconfirmed, travel-sector sources indicated widespread delays, cancellations, and cascading failures, reinforcing concerns around systemic dependency on shared aviation platforms.
Attacks on Aviation and Aerospace
Ransomware actors continue to focus on airports, airlines, suppliers and aviation entities. Qilin emerged in 2026 following a breach at Tulsa International Airport, where unauthorized access and data exfiltration occurred between January 17 and January 20.
Subsequent ransomware tracking linked the incident to Qilin, with stolen data reportedly published on leak sites.
LockBit remains a persistent threat due to its affiliate-driven model targeting large enterprises and critical suppliers.
Its operations are particularly dangerous in aviation supply chains, where disruption to a single vendor can impact downstream airline and airport services.
Cl0p poses a different risk, focusing on data extortion through vulnerabilities in widely used enterprise software.
Given aviation’s reliance on third-party platforms and file transfer systems, such attacks can expose sensitive passenger and operational data without immediate service disruption.
Threat actors such as Scattered Spider are shifting focus toward identity compromise. The group uses help desk social engineering, SIM swapping, and multi-factor authentication manipulation to gain access to enterprise environments.
This tactic is especially effective in aviation, where distributed workforces, contractors, and third-party service providers rely on shared identity systems. A single compromised account can provide access to critical operational platforms.
State-linked groups, including Refined Kitten, Wicked Panda, and Fancy Bear, continue to target aerospace organizations for espionage and long-term access.
These actors focus on intellectual property, aircraft design data, avionics research, and defense-related systems rather than immediate disruption. Their activity raises concerns about persistent access to sensitive aerospace networks and supply chains.
Beyond IT systems, aviation faces growing risks from operational technology and external dependencies.
Airports rely on connected systems for baggage handling, fueling, access control, and ground operations. Disruption to these systems can halt airport functionality even if flight systems remain unaffected.
Additionally, reliance on satellite-based services introduces new vulnerabilities. GNSS spoofing and jamming can interfere with navigation, while attacks on satellite communications or ground stations may impact tracking, weather data, and flight coordination.
The most significant emerging threats in aviation cybersecurity include identity compromise, shared-platform attacks, SaaS exposure, and satellite dependency risks.
Smaller and regional airports are particularly vulnerable due to limited security resources and reliance on third-party providers.
As aviation systems become more interconnected, cyber incidents are increasingly capable of triggering widespread operational disruption, making the sector a high-value and high-impact target for both financially motivated and state-sponsored threat actors.
