Panda SecurityMajor airport problems across Europe in 2025 showed the aviation sector’s vulnerability to cyber threats, especially from ransomware targeting critical vendor systems. These cyberattacks are growing more sophisticated, increasing the risk faced by travellers and industry alike.
This article explores the key lessons from these incidents and outlines the steps airports must take to protect passengers and operations.
Key takeaways
- Airport cyberattacks are increasing in frequency and impact, often exploiting third-party vendor vulnerabilities.
- Network division, vendor management, and manual backup planning are critical for strength.
- Regular staff training and updated cybersecurity frameworks help prevent security issues.
Why airport cyber attacks are on the rise
The air travel sector is a prime target for cybercriminals due to its complex, connected IT environment and the sensitive data it handles. Between January 2024 and April 2025, there was a 600% year-on-year increase in ransomware attacks, with several major airports hit by disruptions.
These incidents highlight how supply chain weaknesses can spiral into chaos across the continent.
The danger of third-party vendor dependency
Recent attacks on Collins Aerospace’s MUSE check-in software illustrate the risks of relying heavily on third-party vendors. When attackers breached the vendor’s system, they disrupted operations at major airports including London Heathrow and Brussels.
Hackers caused widespread delays as airlines were forced to revert to manual processing and physical paperwork to keep travellers moving. This incident highlights the need for thorough vendor risk assessments, security audits, and robust contractual cybersecurity requirements.
Network segmentation: A must for airport security
Effective network segmentation is a fundamental defense against cascading cyberattacks. Airports that isolated their critical systems are able to minimize disruption when attacks occur.
In the USA, the Transportation Security Administration (TSA) now mandates network segmentation for all airports. This approach adds a new layer of resilience. As a result, ensuring that if IT systems are compromised, operational technology can continue functioning.
Human factors and employee training
Human error remains a leading cause of security problems. Phishing and credential theft account for over 70% of attacks in the aviation sector. Regular employee training, phishing drills, and clear incident reporting guidelines are essential for preparing people to play their role in protecting against attacks.
Best practices for air travel cybersecurity (that any industry can steal)
Successful defense against cyberattacks is a combination or people, processes and technology. And the same basic rules can be applied to any industry, not just air travel:
- Conduct regular security audits and risk assessments across all systems.
- Implement network segmentation and air-gapped backups.
- Strengthen vendor management with strict security protocols.
- Provide ongoing cybersecurity training for staff at all levels.
- Develop comprehensive incident response plans with manual.
Conclusion: Building strong airports
The recent wave of airport cyber attacks offers critical lessons for the air travel sector – and beyond. As threats evolve, airports must focus on vendor security, network division, and staff training to protect operations and passenger safety.
By adopting these best practices airports can build a more stronger and secure future.
