The core of the problem was a failure in Collins Aerospace’s Muse software-a cloud-based passenger processing platform used by multiple airlines. Once the ransomware hit, airports were forced to switch to manual check-in and boarding processes. The operational fallout was severe: flight delays, cancellations, long queues, overwhelmed staff.
UK agencies such as the National Crime Agency (NCA) and National Cyber Security Center (NCSC) are working with Collins Aerospace and airport authorities to assess the damage, recover systems, and understand how this could have been prevented.
Key Insights & What This Means for Critical Infrastructure
- Supply-chain risk in vendor software: A platform used by many airlines, once compromised, led to cascading failures. The risk isn’t just your own software, but what you rely on externally.
- Cloud-based dependencies: Cloud services offer scalability and flexibility but also present attack surfaces. If critical services like passenger processing are cloud-hosted, their resilience and fallback plans must be robust.
- Operational resilience matters: Manual fallback procedures, staff training to handle systems down, and redundancy plans are no longer optional. Passengers and airlines alike suffer when operations get stuck.
- Coordination between industry & regulators: Incidents of this magnitude require cooperation-law enforcement, cybersecurity agencies, vendors, and impacted organizations must share intelligence and best practices.
- Importance of ransomware preparedness: Detection, backup & recovery, incident response plans, and risk monitoring for ransomware threats must be top priorities.
How Organizations in Affected Industries Can Respond
Industries most impacted by this event include:
- Aviation & Transportation – airlines, airports, logistics providers
- Critical Infrastructure & Vendor/Software Providers – especially those whose services are in the cloud, used by many clients
- Government & Public Services – public safety, border control, transport regulators
Some steps these organizations should take:
- Audit third-party/ vendor software: Understand which external platforms are critical, review their security posture, evaluate their incident history.
- Implement and test disaster recovery / fallback procedures: Regular drills for system outages; ensure staff know manual procedures.
- Enhance detection & response capabilities: Real-time monitoring for anomalous behavior, ransomware indicators, privileged access abuse.
- Adopt zero trust and least privilege models: Restrict the blast radius of any compromised system.
- Regulatory compliance & reporting: In many jurisdictions, such disruptions trigger mandatory reporting, compliance investigations, or fines. Ensuring readiness to comply with GDPR, industry-specific rules, etc.
Conclusion
The recent arrest tied to the airport ransomware attack underscores just how interconnected and vulnerable modern systems are. A single vulnerability in vendor software, especially in the cloud, can ripple out and grind large portions of public infrastructure to a halt. For organizations in aviation, critical infrastructure, government, and any business relying on external cloud services, robust preparedness isn’t just good practice-it’s essential. Defensive layers, tested contingencies, and strong vendor oversight are key to limiting damage when (not if) such incidents happen.
