The aviation and aerospace industries have emerged as primary targets for ransomware and data extortion groups throughout 2025 and 2026. These cybercriminals are exploiting vulnerabilities in various systems, from passenger-processing platforms to satellite-dependent navigation systems, aiming to cause widespread disruption.
The Interconnected Risk of Aviation Systems
In the aviation sector, the risk is amplified due to its interconnected nature. Various stakeholders, including airlines, airports, and maintenance providers, operate within a complex ecosystem. An attack on a single entity can trigger a chain reaction, leading to significant operational disruptions.
An example of this occurred in September 2025 when Collins Aerospace’s MUSE platform suffered a ransomware attack. This incident caused major interruptions at several European airports, including Heathrow and Brussels, highlighting the widespread impact of such cyber threats.
Ongoing Cyber Threats in 2026
The threat landscape has remained active in 2026, with reports of cyber-related disruptions at European airports in April. These incidents affected various aspects such as check-in and baggage handling, emphasizing the persistent pressure on aviation IT systems.
In January 2026, the Tulsa Airports Improvement Trust reported unauthorized access to its systems, which was linked to the Qilin ransomware group. This incident underscores the ongoing vulnerabilities within the sector.
Prominent Threat Actors and Mitigation Strategies
Analysts from PolySwarm have identified several threat actors and malware families targeting the industry, including groups like Scattered Spider and ransomware such as LockBit and Cl0p. The aviation sector must address shared IT platforms and supply chain vulnerabilities to mitigate these risks.
Identity-based intrusion, particularly from groups like Scattered Spider, poses a significant threat. This group uses sophisticated techniques like social engineering and SIM swapping to exploit identity systems, which can lead to widespread access across multiple organizations.
Enhancing Cyber Resilience in Aviation
To enhance resilience, the aviation sector should prioritize the security of shared IT platforms and conduct regular contingency planning for manual operations. Enhanced identity verification processes and regular security assessments of third-party vendors are crucial.
Moreover, planning for GNSS interference and satellite dependency is essential, especially for routes in geopolitically sensitive areas. By addressing these vulnerabilities, the aviation industry can better protect itself against escalating cyber threats.
