Connected airport and airline systems face cybersecurity risks because aviation depends on digital systems and data flows that cross organizational and national borders. The International Civil Aviation Organization (ICAO) says digital transformation can improve efficiency and capacity while exposing aviation stakeholders to threats that may affect finances, reputation, service continuity, and the safety and security of people and facilities. That describes potential consequences—not proof that a cyberattack has compromised flight safety.
The available official material supports concern about cyber risk, but it does not establish a verified sector-wide increase in attacks. The headline’s “growing” claim should therefore be read as a warning about expanding digital dependence, not as a confirmed attack-growth statistic.

Are airports and airlines vulnerable to cyberattacks?
Yes. ICAO describes aviation as increasingly interconnected, with systems and data flows extending across organizations and borders. IATA says airlines can attract actors seeking data or money, or aiming to disrupt operations or cause harm. Those descriptions identify exposure and motives; they do not establish that every airport or airline has been attacked, or that every connected system is reachable from the public internet.
The scope extends beyond an individual airline or airport. Aviation services depend on relationships among operators, States, suppliers, and other stakeholders. A weakness or disruption affecting one part of that network can matter to others, which makes cybersecurity both an organizational and an international coordination issue.

Why do connected aviation systems create cyber risk?
More digital dependencies mean more connections to manage
Digitization can support efficiency and capacity, but systems that exchange information or depend on shared technology create dependencies that need to be understood and protected. The practical challenge is not simply counting internet-connected devices: organizations need visibility into the systems, data flows, vendors, and services on which their operations rely.
Suppliers and older systems can complicate oversight
IATA’s 2025 Annual Review discusses legacy-system exposure and supplier risk management. That is a reason to assess technology and vendor dependencies, not evidence that every older system is insecure. An organization needs to know where suppliers support important services, what dependencies exist, and how a disruption could affect continuity.
Can a cyberattack disrupt airport or airline operations?
It can potentially affect service continuity, as well as finances and reputation. ICAO also identifies possible effects on the safety and security of people and facilities. These are possible consequences of aviation cyber threats, not evidence that a particular attack has caused an unsafe flight or compromised aviation safety.

It is also important to distinguish a cyberattack from a technology outage. IATA’s 2025 Annual Review cites the July 2024 CrowdStrike outage as a reminder of aviation’s dependence on cybersecurity, while describing it as the result of a faulty update. It is relevant as an example of how a technology failure can disrupt services; it should not be described as a cyberattack.

What are aviation organizations doing about cybersecurity?
The official guidance in view emphasizes risk assessment, supply-chain oversight, continuity, and coordination rather than a single universal fix. ICAO assigns work across international, national, and stakeholder levels; IATA provides operator-focused resources and describes standards work in development.
| Approach | What it covers | What that means for an organization |
|---|---|---|
| ICAO Cybersecurity Action Plan | ICAO says its first edition was published in November 2020 and its second in January 2022. The plan develops the seven pillars of ICAO’s Aviation Cybersecurity Strategy into 32 priority actions and 51 tasks for ICAO, States, and stakeholders. | Cybersecurity is treated as coordinated work involving international, national, and industry participants, not only an internal IT matter. |
| IATA Aviation Cybersecurity Library | The library lists Cybersecurity Risk Assessment Guidance Material and Cybersecurity Supply Chain Oversight Guidance Material. | Operators can use these resources to examine risk coverage and supplier dependencies. |
| IATA cybersecurity standards work | IATA says it is developing IOSA Standards and Recommended Practices for Cybersecurity for Safety, Security and Airworthiness. | This is work in development; it should not be mistaken for a universally adopted requirement or a regulation. |
ICAO’s guidance index also references protection of critical civil aviation infrastructure and collaboration with external authorities, including cybersecurity, military, and national security authorities. Some referenced manuals are restricted, so their detailed contents should not be assumed from the index alone.

A verified, named statistic showing the rate of cyberattacks specifically against connected airports and airlines was not established in the material cited here. A 131% increase figure appeared in a regional aviation seminar presentation and was attributed to the European Regions Airline Association in 2024, but the underlying report, scope, and methodology were not confirmed. It is not a sound basis for describing a sector-wide attack increase.
That limitation does not mean aviation cyber risk is unimportant. ICAO and IATA describe meaningful exposure and potential consequences, while IATA’s 2025 Annual Review addresses data breaches, cyber threats, legacy systems, access management, and supplier risk management. These sources support attention to the risk; they do not provide a verified, comparable time series establishing how attack frequency has changed.

How should readers interpret claims about aviation cyber incidents?
- Separate risk from incident: a vulnerability or potential impact is not proof that an attack occurred.
- Separate incident from consequence: an attack or outage does not, by itself, establish an effect on flight safety.
- Check the cause: a faulty update or other technology failure is not automatically a cyberattack.
- Check the measurement: an attack-growth percentage needs a defined geography, time period, incident scope, and methodology before it can be generalized.
For aviation professionals, IATA’s Aviation Cybersecurity Library is a relevant starting point for its risk-assessment and supply-chain oversight materials. ICAO’s action plan offers the broader picture of coordination among ICAO, States, and stakeholders.
