Cyber risk in the global aviation and aerospace sector is rapidly evolving, with a marked shift toward ransomware, identity-based intrusions, and platform-level disruptions.
This highly interconnected ecosystem presents a uniquely attractive target due to its time-sensitive operations, massive volumes of valuable data, regulated safety environments, and complex third-party dependencies.
Shared airport IT platforms remain a significant single point of failure across the industry.
The September 2025 cyberattack starkly demonstrated the systemic risk posed by shared aviation platforms to the Collins Aerospace MUSE passenger-processing system.
CSO Online reported that this verified ransomware incident disrupted check-in, boarding, and baggage operations at multiple major European hubs, including Heathrow, Brussels, Berlin, and Dublin, forcing staff to rely on manual fallback procedures.
The vulnerability of shared operational infrastructure was highlighted again during a separate wave of cyberattacks on European airports in early April 2026.
Travel-sector sources indicated widespread delays, missed connections, and cancellations, though public technical attribution for this specific event remains limited.
Major ransomware syndicates and data extortion groups maintain a heavy focus on aviation suppliers and supporting vendors.
LockBit remains a significant threat due to its history of compromising critical enterprises whose outages directly disrupt downstream airline functions.
Cl0p poses a similar supply chain danger, compromising widely used enterprise software to expose sensitive passenger and engineering data without necessarily causing immediate operational downtime.
While financially motivated attacks cause the most visible public disruption, advanced persistent threat groups focus heavily on strategic espionage.
MITRE identifies Refined Kitten as a prominent actor targeting aviation for long-term pre-positioning and credential theft.
Wicked Panda operates with a similar long-term focus, targeting aerospace entities to steal intellectual property, aircraft design data, and proprietary manufacturing processes.
Fancy Bear targets defense-adjacent aerospace organizations for intelligence collection related to military aviation and satellite programs.
As these diverse threats converge, the aviation industry must treat its infrastructure as a system-of-systems cyber target.
Emerging threat vectors now include exposure from smaller regional airports with lower security maturity, aviation software-as-a-service vulnerabilities, and interference with satellite-enabled navigation.
PolySwarm currently tracks multiple malware samples and indicators of compromise associated with these profiled threat actors, providing crucial support for faster threat triage and operational continuity in environments where safety is paramount.
