september 22, 2025

European Airports Grapple With Disruptions Following Cyberattack

Major airports across Europe experienced significant disruptions this weekend following a widespread cyberattack that targeted critical luggage and passenger registration systems. The incident,which began Friday night,caused flight cancellations and significant delays for thousands of travelers.

Affected Airports and Initial Response

Airports in Berlin, Brussels, and London were among the first to report interruptions, with electronic systems failing to process passengers and luggage efficiently. Airline staff were forced to revert to manual procedures, including hand-writing boarding passes and utilizing backup computer systems. While not all European airports were impacted, the disruption caused a ripple effect across the continent’s air travel network.

Software Provider Identified

The source of the attack was identified as software provided by Collins Aerospace, a United States-based company specializing in aviation technology. The company confirmed a “cybersecurity-related interruption” affecting its systems, which are used for passenger registration, baggage handling, and dispatch.RTX Corporation, Collins Aerospace’s parent company, stated they were actively working to resolve the issue.

According to RTX, the impact was primarily limited to customer billing and luggage dispatch, which could be partially mitigated through manual processes. Airports swiftly implemented contingency plans, including activating backup systems and relying on laptops to manage essential functions. Passengers were advised to check flight statuses and explore alternative check-in options.

Brussels Airport Hit Hardest

While London Heathrow and Berlin Brandenburg Airport showed signs of recovery, Brussels Airport continued to experience significant challenges. As of sunday,45 departure flights had been canceled,with six diverted,out of a total of 257 scheduled flights. Delays ranged from 30 to 90 minutes. The airport authorities requested airlines to cancel half of the 276 flights planned for Monday due to the ongoing issues with the billing system and the lack of a secure software update from Collins Aerospace.

European Commission Assures Safety

The European Commission assured the public that aviation safety and air traffic control operations were not compromised by the cyberattack. Officials emphasized that there was no immediate indication of a widespread or severe attack with broader implications. Investigations are underway to determine the origin and extent of the incident.

## Summary of the Aviation Cybersecurity Incident & Analysis

The Scope of the Disruption: A Continent Grounded

On September 22,2025,European airspace experienced notable disruption following a large-scale cyber attack targeting Collins aerospace,a leading provider of flight management systems (FMS). The attack, initially detected late on September 21st, impacted the functionality of FMS software used by numerous airlines across the continent, leading to widespread flight delays, flight cancellations, and significant air traffic control challenges. Initial reports indicate the attack leveraged a elegant ransomware variant, though attribution remains under investigation by international cybersecurity agencies. The incident highlights the growing vulnerability of the aviation industry to cybersecurity threats.

* Affected Regions: Primarily impacting airports in the UK, Germany, France, Italy, and Spain, with ripple effects felt across the entire european Union airspace.

* Airlines Impacted: British Airways, Lufthansa, Air France-KLM, Ryanair, and EasyJet have all confirmed disruptions to their schedules.

* Estimated Impact: Over 1,500 flights cancelled and several thousand delayed as of 09:00 GMT, affecting an estimated 250,000+ passengers.

Understanding the Target: Collins Aerospace FMS & Aviation Cybersecurity

Collins Aerospace‘s Pro Line Fusion and earlier generation flight management systems are integral to modern aircraft operation. These systems handle crucial functions including:

1. Navigation: calculating optimal flight paths and guiding aircraft.
2. Performance Management: Optimizing fuel efficiency and monitoring aircraft performance.
3. Flight Planning: Loading and executing pre-defined flight plans.
4. Autopilot Integration: Providing data to the autopilot system for automated flight control.

The attack didn’t directly compromise aircraft control systems, but rather the ground-based software used for updating and maintaining the FMS databases. This meant airlines were unable to reliably certify the integrity of the flight plans loaded onto aircraft, forcing them to ground planes or operate under severely restricted conditions. This incident underscores the critical need for robust aviation cybersecurity measures, including threat intelligence, vulnerability management, and incident response planning. The supply chain risk associated with relying on third-party software providers like Collins Aerospace is also a key takeaway.

Technical Details of the Cyber Attack: Ransomware & Data Integrity

While the full extent of the breach is still being assessed, preliminary investigations suggest the attackers exploited a vulnerability in a remote access tool used by Collins Aerospace engineers. The ransomware employed appears to be a new variant, exhibiting characteristics of both LockBit and Clop ransomware families, suggesting a possible collaboration or evolution of existing threats.

* Attack Vector: Initial access gained through a compromised VPN connection.

* Ransom demand: Reports indicate a significant ransom demand in cryptocurrency, though Collins Aerospace has not publicly confirmed this.

* data Exfiltration: Evidence suggests potential data exfiltration, including sensitive flight planning data and possibly proprietary software code. This raises concerns about future attacks and the potential for reverse engineering of the FMS software.

* Impact on ATC: The disruption also impacted air traffic control systems reliant on data feeds from affected airlines, leading to congestion and delays.Eurocontrol, the European Organisation for the Safety of Air Navigation, issued a statement urging airlines to implement contingency plans.

Regulatory Response & Industry Collaboration: A Coordinated Effort

The European Union Aviation Safety Agency (EASA) promptly issued an emergency airworthiness directive, requiring airlines to verify the integrity of their FMS databases before operating flights. National aviation authorities, including the Civil Aviation Authority (CAA) in the UK and the Luftfahrt-Bundesamt (LBA) in Germany, are working closely with airlines to implement the directive.

Key Actions Taken:

* EASA Emergency Directive: mandating FMS database verification.

* National Aviation Authority Oversight: Providing guidance and support to airlines.

* Cybersecurity Incident Response Teams: Activated to assist with investigation and remediation.

* Information Sharing: Increased collaboration between airlines, software providers, and cybersecurity agencies to share threat intelligence.

* NIST Cybersecurity Framework: Airlines are being urged to review and strengthen their cybersecurity posture based on the NIST Cybersecurity Framework.

Real-World Example: The 2023 British Airways IT Outage – A Precursor?

While not a direct cyber attack on flight management systems, the significant IT outage experienced by British Airways in 2023, which grounded hundreds of flights, serves as a stark reminder of the potential for disruption caused by IT failures within the aviation sector. That incident, attributed to power supply issues, highlighted the interconnectedness of airline systems and the cascading effects of even seemingly isolated failures.The current Collins Aerospace attack demonstrates a far more targeted and sophisticated threat, emphasizing the need for proactive cyber resilience.
