Editor’s Note: A single breach shut down Europe’s busiest airports—this weekend’s cyberattack on Collins Aerospace’s MUSE platform exposes a stark truth: modern aviation’s digital convenience comes at the cost of dangerous interdependencies. As airport terminals fell back to handwritten baggage tags and overwhelmed staff, cybersecurity, information governance, and eDiscovery professionals must confront the broader implications of a system-wide collapse rooted in a single point of failure. This incident isn’t just a disruption—it’s a warning. In an era where digital efficiency drives global industries, this cyberattack reveals the fragile foundations supporting critical infrastructure and underscores the urgent need for resilient supply chain strategies, dual-capability operations, and regulatory readiness.

European Aviation Grounded by Cyberattack as Single Point of Failure Cripples Systems
ComplexDiscovery Staff
The digital heartbeat of European aviation flatlined Friday night when a sophisticated cyberattack crippled check-in systems across the continent’s busiest airports. The assault on Collins Aerospace’s MUSE platform transformed bustling terminals into chaotic scenes reminiscent of air travel’s pre-digital era, with airport staff frantically scribbling baggage tags by hand while thousands of passengers faced mounting delays.
Brussels Airport first confirmed the Friday night, September 19th, breach against Collins Aerospace’s check-in and boarding systems, which affected multiple European airports and forced operations to revert to manual procedures. The attack struck at the core of modern airport efficiency, targeting what industry experts describe as aviation’s most vulnerable single point of failure.
Collins Aerospace, a subsidiary of defense giant RTX Corporation, acknowledged a “cyber-related disruption” to its MUSE (Multi-User System Environment) software at select airports. The platform, which enables passengers to check themselves in, print boarding passes, tag bags, and dispatch luggage through automated kiosks, suddenly became inoperable across Europe’s major hubs.
The Ripple Effect Spreads
At Heathrow, Brussels, and Berlin airports alone, 29 departures and arrivals were cancelled, affecting operations at facilities that collectively handle over 1,100 scheduled flights daily. The disruption extended beyond these primary targets, with Dublin and Cork airports in Ireland reporting minor impacts from the “Europe-wide software issue.”
Maria Casey, traveling through Heathrow’s Terminal 4 to Thailand, experienced the chaos firsthand. “They had to write our baggage tags by hand,” she reported after spending three hours in check-in queues. “Only two desks were staffed, which is why we were cheesed off.”
The human cost extended far beyond inconvenience. Airport terminals became pressure cookers of frustration as automated systems that typically process hundreds of passengers per hour ground to a halt. Traditional check-in counters, downsized in the digital age, suddenly bore the full weight of processing thousands of travelers manually.
Brussels Airport ordered airlines to cancel approximately 50% of Sunday departures to prevent terminal overcrowding, signaling that recovery efforts would stretch well into the weekend. The decision reflected a harsh reality facing airport operators: rebuilding operational capacity after a digital collapse requires more than simply flipping switches back on.
Exposing Aviation’s Digital Achilles’ Heel
Charlotte Wilson, head of enterprise at Check Point cybersecurity firm, identified the aviation industry as an “increasingly attractive target” for cybercriminals due to its heavy reliance on shared digital systems. The Collins Aerospace attack exemplified this vulnerability perfectly.
MUSE has become deeply embedded in the daily operations of dozens of airports worldwide, transforming Collins Aerospace into a critical supplier not only to airlines but also to national aviation authorities. This shared-use approach, while celebrated as a cost-saving efficiency booster, created what Friday’s events exposed as a dangerous single point of failure.
The sophistication of the attack impressed industry analysts. Travel expert Paul Charles described it as “a very clever cyberattack indeed because it’s affected a number of airlines and airports at the same time — not just one airport or one airline, but they’ve got into the core system that enables airlines to effectively check in many of their passengers.”
A Surge in Aviation Cyber Threats
Friday’s attack occurs against a backdrop of escalating digital threats targeting the aviation sector. Industry data indicates a dramatic surge in aviation cyberattacks, with some reports suggesting increases of several hundred percent between 2024 and 2025, transforming cybersecurity from a peripheral concern into an existential threat for airlines and airports worldwide.
James Davenport, an information technology professor at the University of Bath, noted the attack’s unusual characteristics: “It looks almost more like vandalism than extortion, based on the information we have.” This assessment suggests the perpetrators prioritized disruption over financial gain, a troubling evolution in cyber threat motivations.
The timing proved particularly damaging, striking during peak weekend travel when airports operate near capacity. Industry observers noted similarities to previous supply chain attacks, including the 2024 CrowdStrike incident that demonstrated how single-vendor dependencies can cascade into global disruptions.
Recovery Challenges and Lessons Learned
European Commission spokesperson confirmed no indications of a “widespread or severe attack” while investigations continued into the incident’s origin. However, the measured official response contrasted sharply with the operational chaos unfolding across European terminals.
For cybersecurity and information governance professionals, the Collins Aerospace breach offers sobering lessons about supply chain resilience. Organizations implementing shared-service models must weigh efficiency gains against concentration risks. The attack demonstrates how third-party dependencies can transform localized incidents into international crises within hours.
Effective incident response planning requires more than technical recovery procedures. Airports must maintain sufficient manual processing capabilities to handle surge capacity when digital systems fail. This dual-capability approach, while expensive, provides essential operational continuity during cyber incidents.
Organizations should also establish redundant vendor relationships to avoid single points of failure. The Collins Aerospace disruption showed how monopolistic dependencies in critical infrastructure can amplify attack impacts exponentially.
eDiscovery and Compliance Implications
The breach raises important questions about data handling and discovery obligations during cyber incidents. When automated systems fail, organizations must ensure manual processes maintain compliance with data protection regulations. The handwritten baggage tags and manual passenger processing at affected airports created potential gaps in audit trails and customer data handling procedures.
Information governance professionals should note how system outages can disrupt normal data retention and processing workflows. The incident highlights the need for comprehensive business continuity plans that address both operational recovery and regulatory compliance during extended system downtime.
The Path Forward
Rafe Pilling, director of threat intelligence at Sophos, emphasized that the incident highlighted “the fragile and interdependent nature of the digital ecosystem underpinning air travel”. As recovery efforts continue, the aviation industry faces challenging questions about striking a balance between efficiency and resilience.
The Collins Aerospace attack serves as a watershed moment for aviation cybersecurity. Industry leaders must now confront whether current shared-service models adequately protect against sophisticated threat actors. The answer may require fundamental changes to how airports and airlines architect their digital infrastructure.
For cybersecurity professionals, the incident underscores the importance of supply chain risk assessments and third-party security monitoring. As digital dependencies deepen across all industries, the aviation sector’s weekend of chaos provides a preview of vulnerabilities that extend far beyond airport terminals.
Has your organization assessed whether its critical systems contain similar single points of failure that could transform a targeted cyberattack into an enterprise-wide crisis?
