Imagine a typical, very busy airport on a Monday morning: there is the sound of rolling suitcases, the hiss of espresso machines, and the rhythm of boarding announcements. Suddenly, that rhythm stops. Check-in kiosks get frozen. Baggage belts get stopped. Staff members who are used to working with high-tech tools tet out their pens and clipboards. This is not the plot for a disaster flick; it’s the very disruption that spread almost everywhere in Europe during a European airport cyberattack that hit the passenger-processing systems of several airports. As per Gartner, by 2026, 75% of organizations will suffer operational disruptions due to vendor cyber-risk failures.
The incident is a case study for busy professionals, tech enthusiasts, and security leaders, not just a headline. The question is: how could a single cyber event not only stop flights but also harm reputations and test the resilience of one of the most tightly regulated industries in the world in such a short time? In this article, you will discover the truth of the facts, the reasons why the crisis was so important even for the sectors outside of aviation, and what concrete steps leaders can take to build up their own organizations.
What Actually Happened
On the weekend from Friday night to early Monday, multiple European airports, including Heathrow (UK), Brussels (Belgium), and Berlin (Germany, faced severe disruptions in their automated passenger-processing systems. One of the first official statements about the incident was made by the police in Britain, and CNN and CNBC were among the first media outlets to report on the event.
The incident was a ransomware attack that had as its goal a commonly used third-party platform for passenger processing activities (Collins Aerospace’s Multi-User System Environment or MUSE), as reported in a statement of several involved airports.
On-board technology, self-service stations, and common airport check-in desks belong to this platform. So, it turned out that the only solution to the failure of the systems was the manual check-in and boarding mode-somewhat of a nightmare for the countless passengers. Many flights were delayed or canceled, but not due to safety concerns with the aircraft. It was rather a digital “front door” to aviation that was the culprit of the chaos – passenger processing had been locked by code.
The safety of the passengers was not compromised at all; still, the cost for the operations was exorbitant: longer queues, missed connections, increased staffing needs, and a flood of social media frustration.
Why This Wasn’t “Just Another IT Issue”
The term “cyberattack” usually sounds like an unimaginable thing when you are a traveler, but if you find yourself in an exit queue that stretches for a long way, then you realize how real it is. However, for security officers, it is a classic example of a supply-chain compromise. In order to save money and time, airlines and airports have been increasingly handing over necessary operations to specialist vendors. What is being lost is the risk of concentration – an outage of one supplier can affect the rest of the world.
This is a “wake-up call” for all the businesses that are relying on third parties. You may be exposed to such risks if your billing, HR, or customer-facing platforms are hosted by a vendor. Aviation, on the other hand, is the only one that makes this invisible at the level of scale. McKinsey states here that third-party incidents cost 45% more to recover than internal incidents.
The Anatomy of the Attack in Plain English
MUSE is a shared backbone model. Through it, the steps of check-in, bag-drop, and boarding are accessed for numerous airlines. If a successful ransomware attack on its infrastructure is carried out, basically, it “unplugs” every single client that is connected. Neighborhood networks in each airport are not relevant any longer, because with the centralized service, there is a possibility for failure in one place only.
Since the beginning, security researchers and the EU Agency for Cybersecurity (ENISA) have been warning about the ransomware attacks in critical infrastructure. As per the information, in 2024 alone, ENISA indicated that aviation is one of the top five sectors most exposed to the risk of a third-party compromise. This incident lifts the veil and unveils the truth of the prediction.
Immediate Response: How Airports Kept Planes Flying
On the contrary, airports were very much operational despite the extent of the crisis. Business continuity plans were put into operation, which featured the following:
Manual check-in and boarding: The airline personnel, in cases where the system was down, would print boarding passes from the backup system or even issue them manually.
Extra personnel: Off-duty personnel and contractors were summoned to direct the pedestrians and to manage the queues.
Passenger communication: Social media traffic and terminal announcements were a helpful means for calming down the crowd as they provided real-time updates.
Vendor and government coordination: Computer Emergency Response Teams (CERTs), law enforcement, and the vendor worked collectively to address the breach and remediate it.
Such moves demonstrated the effectiveness of continuity planning, which, however, also showed the level of human and financial energies that could be potentially expended in large-scale manual fallback situations.
Lessons for Security Leaders: Turning a Crisis into a Playbook
Crisis is your CISO, CI, O, or operations leader. This incident is more than just a headline – it’s a sign for you to take a break, ask: “If this happened to us tomorrow, how far would our feet reach?”
This is a people-friendly checklist that you can immediately implement:
Know your lifelines. Draw a network diagram showing which partners are vital for your business to operate. If one of them went completely dark, which services would be stopped due to a lack of backup? Make a short list of these.
Build firebreaks. Part your networks so a vendor’s breach isn’t the easiest way to penetrate your main environment. You should think of this as the firewall between their house and yours.
Run & what-if & drills. Don’t just have a continuity plan; rehearse it. Act out a vendor outage with your team and practice the manual fallback till it becomes second nature.
Don’t ask for promises, ask for proofs. Request penetration testing reports, SOC 2 or ISO 27001 certifications, and actual recovery time objectives from your suppliers and then genuinely go through them. Gartner states that <30% of CIOs have fully tested vendor continuity plans in the past year.
Borrow good playbooks. The reason is public for a few frameworks, like CISA’s StopRansomware and NIST’s Incident Response guides. Don’t keep them only on your shelf; rather, use them as templates.
Words will not help you if they are not ready beforehand. Write in advance passenger or customer notices so when the pressure is on, you can communicate within minutes and not hours.
A partner’s cyber incident can thus, in a twinkling, become your brand’s headline. One of the highest-ROI moves is that you treat preparation as your routine professionalism, rather than paranoia.
Strategic Shifts Boards Should Drive
It is not an issue that concerns only the IT department; rather, it is a boardroom discussion. So what the management can do is:
Procurement that has power. Recovery SLAs, rights to audit, and ramifications if a vendor fails to give you protection should be clearly stated in contracts.
Do not put your money on a sole horse. Supply diversity strategy is the move to mitigate the risk of having only one supplier that can bring your company to a standstill.
Insurance that truly insures you. First of all, you have to make sure that your cyber insurance is set with an eye on supply chain events, and that such occurrences are considered as included rather than excluded.
Train together as a team. Besides joint exercises and practice, regulators, vendors, and operators also need to exchange real-time information and not just situational reports after an incident.
These steps are worth far less than the cost of ground stops, angry customers and are the ones that build trust well before it is required.
The Human Side – Passengers and Employees
We are often drawn to the systems when talking about technology, but in fact, behind every cyber headline, there’s a very human story. People have missed weddings, funerals, and very important meetings. Frontline staff have been on the receiving end of stress, and they have been working overtime to process the travelers manually. In this situation, for security leaders, cyber resilience should be a very clear and strong reminder that it’s not only about data; it’s about people. Enhanced security measures for vendors go a long way in maintaining employees’ and customers’ trust.
Moreover, just a little humor never hurts. A stranded flyer wrote on Twitter, “In the digital era, it was still faster for me to board with my handwritten pass.” Sometimes the most trivial jest can make the longest delay feel lighter.
Bringing It Home
Among other things, the European airport cyberattack has demonstrated the power of continuity planning, open lines of communication, and public-private cooperation in preventing the stoppage of flights. Summing up what professionals can learn from this text, it is: depicting third-party cyber risk as the issue of board-level priority, putting your response to the test in real scenarios, and demanding as much resilience as innovation in your organization.
Indeed, in a world where everything is so inextricably intertwined, malware in one vendor’s system is going to mean that you will be delayed shortly. Gartner says 80% of boards will include cybersecurity as a top-three business risk by 2026.
Conclusion – The Sky Isn’t Falling, but It’s Sending a Signal
The European airport cyberattack serves as a strong signal that in a hyper-connected world, your ability to manage crises depends largely on the least prepared of your suppliers. The mishap of just one platform caused widespread disruption to travellers and made the staff overwhelmed. However, the incident demonstrates that, when contingency plans are in place, communications are open, and cooperation takes place, then the safety of the system, even in the face of challenge, is ensured.
Both for security leaders and board members, the key takeaway is: third-party cyber risk can no longer be kept away in the back office as only a compliance issue. It is an issue for the boardroom, for the brand, and for people. Know the locations of your vulnerabilities, practice your reaction, and build relationships before a crisis. Let the resilience you equally demand as much as innovation be the one you fiercely demand.
Indeed, in the current sky of interconnected systems, the malware of a single vendor is going to be your delay very soon – but if you are equipped with the foresight, it doesn’t have to happen.
FAQs
1. What is the Collins Aerospace MUSE platform?
MUSE (Multi-User System Environment) is a common system for passenger handling shared by airlines and airports. It allows the running of check-in kiosks, bag-tag printers, and desk software through the user interface.
2. Can we say that the cyberattack affected the safety of flights?
The answer is No. The attack only targeted passenger-processing systems, and not aircraft operations or safety systems. Consequently, the flights were delayed or cancelled only for logistical reasons.
3. What is the reason supply-chain cyberattacks are so disruptive to the aviation sector?
Impacted by the multitude of airlines and airports relying on the very same vendor for their critical services, hence, a single breach can easily affect several hubs simultaneously.
4. How can airports and airlines avoid similar problems?
They are advised to segment networks, rehearse manual fallback, insist on stronger security evidence from vendors, diversify suppliers, and collaborate closely with regulators and CERTs.
5. What are the takeaways of non-aviation businesses from this case study?
Organizations that use outsourced or cloud services should have a clear map of vendor dependencies, require vendor transparency, and continuity plan testing – because a supplier’s cyber incident can instantly become your outage.
