When passengers at London Heathrow, Brussels and Berlin airports were forced into manual check-in procedures on 20 September 2025, few realised they were witnessing a preview of hospitality’s cybersecurity future—one where a single vendor compromise can cascade across entire industries.

## The Attack Breakdown

The ransomware attack on Collins Aerospace’s MUSE system began on 19 September, targeting the Multi-User System Environment software that powers passenger check-in, baggage processing and boarding operations across multiple European airports. The [EU cybersecurity agency ENISA confirmed ransomware as the cause](https://www.reuters.com/business/aerospace-defense/eu-agency-says-third-party-ransomware-behind-airport-disruptions-2025-09-22/), though the specific strain and ransom demands remain undisclosed.

Major airports including Dublin and Cork joined the list of affected facilities as the attack’s scope became clear. Berlin Brandenburg Airport warned of continued delays and cancellations as of 25 September, whilst Collins Aerospace worked to restore full functionality to its customers. The disruption highlighted the centralised nature of aviation technology infrastructure, where shared software platforms create single points of failure across international networks.

Recovery efforts involved coordinated responses from the UK National Cyber Security Centre, law enforcement agencies and Collins Aerospace itself, though [no definite timeline for complete recovery has been established](https://www.csoonline.com/article/4060804/european-airports-continue-to-crawl-after-a-cyberattack-on-collins-muse-systems.html). The [ransomware attack’s widespread impact on European aviation](https://www.sovereignmagazine.com/article/collins-aerospace-cyber-attack-grounds-thousands) demonstrates the vulnerability of critical infrastructure systems.

## Travel Industry Consequences

The aviation attack serves as a stark warning for hospitality companies that increasingly rely on similar interconnected digital systems. Industry data shows [31% of hospitality organisations experienced data breaches](https://www.helpnetsecurity.com/2025/07/03/hospitality-industry-cybersecurity-challenges/) in 2025, with average costs reaching $4.03 million per incident.

Hotel property management systems face comparable vulnerabilities to aviation platforms, with cybercriminals exploiting unpatched systems and targeting shared technology vendors. The recent Otelier breach affected multiple hotel brands through a single vendor compromise, mirroring the Collins Aerospace incident’s impact pattern. Connected devices within hotels, from point-of-sale terminals to [hotel room amenities upgrade](https://safemark.com/) systems, constitute approximately 60% of cyberattack targets in the sector.

The threat extends beyond individual properties. [The SITA Passenger Service System breach](https://www.smartbrief.com/original/here/travel-industry-can-fight-back-against-cyberthreats) demonstrated how aviation cybersecurity incidents can expose data from over 580,000 customers across multiple airlines, illustrating the cross-pollination of risk between travel industry segments.

### Shared Infrastructure Risks

The reliance on shared technology vendors amplifies vulnerabilities across both aviation and hospitality. When security failures occur at vendor level, the impact spreads to multiple clients simultaneously. This interconnected model, whilst cost-effective, creates systemic risks that individual companies struggle to mitigate independently.

Analysis shows only a small fraction of airlines and airports maintain adequate cybersecurity preparedness, a trend that mirrors challenges in hotel technology management. The same vendor relationships that streamline operations also create attack vectors that span industry boundaries, as seen in [connected vehicle systems facing similar third-party security risks](https://www.sovereignmagazine.com/article/automotive-cybersecurity-crisis-growing-threats-to-connected-vehicle-systems).

## Building Better Defences

The Collins Aerospace incident demands immediate action across travel industries. Investment in cybersecurity infrastructure must include comprehensive backup systems and vendor diversification strategies to eliminate single points of failure. Major hotel chains like Hyatt have initiated bug bounty programmes to identify vulnerabilities before malicious actors exploit them.

Enhanced staff training programmes and incident response protocols have become essential, particularly as [AI-driven attacks increase in sophistication](https://www.sovereignmagazine.com/article/uk-warns-of-ai-advancements-threatening-global-cybersecurity-systems). The manual operations that kept airports functioning during the MUSE system outage required trained personnel capable of reverting to non-digital processes—a capability many hospitality venues lack.

Regulatory implications loom as the [UN aviation gathering highlighted cybersecurity concerns](https://www.reuters.com/sustainability/climate-energy/un-aviation-gathering-opens-under-shadow-cyberattacks-geopolitical-tensions-2025-09-23/) alongside geopolitical tensions. Industry observers expect stricter vendor vetting requirements and mandatory resilience testing for critical systems, especially as [national cybersecurity defence strategies evolve](https://www.sovereignmagazine.com/article/why-the-salt-typhoon-hack-changes-everything-about-national-cybersecurity-defence) to address sophisticated threat actors.

The Collins Aerospace attack serves as both a wake-up call and a blueprint for the travel industry. As hotels and hospitality companies increasingly rely on interconnected digital systems for everything from guest check-in to room security, the lessons learned from September’s aviation chaos may well determine whether the industry’s digital transformation enhances or compromises guest safety and operational resilience. [The hundreds of thousands of passengers affected](https://gigazine.net/gsc_news/en/20250922-heathrow-brussels-berlin-airports-flights-delayed-cyberattack) represent just a fraction of the potential impact if similar vulnerabilities remain unaddressed across travel’s expanding digital networks.
