When automation fails: Lessons in cyber resilience from Europe’s airport ransomware attack

This past weekend, millions of travelers faced a modern nightmare: delays, cancellations, and chaos at some of Europe’s busiest airports – Heathrow, Brussels, Berlin – triggered by a ransomware attack on Collins Aerospace’s check-in and boarding software. It's very much the reality of today’s hyperconnected infrastructure.

This shows how hidden cyber risks can be. It also shows how unprepared many important systems are for these kinds of threats.

This also shows how the vulnerability of supply chains can put businesses in trouble. Collins Aerospace isn’t an airport or airline but a software vendor, a third-party provider whose systems connect together vast and complex air travel operations.

This sort of third-party risk is increasingly a preferred target for ransomware gangs. A flaw in one vendor’s software can cascade through the global transportation ecosystem, unleashing disruption across an entire continent.

The lesson here is that just making your own computers and firewalls stronger isn’t enough. Real protection means keeping a close eye on every part of your supply chain. Are vendors’ security practices robust? Do contracts demand transparent vulnerability disclosure? Is patch management swift and audited? Those questions are foundational.

Then, there’s the often-overlooked fallback mode: manual operations. This hack blew up the digital convenience airports pride themselves on: automated check-ins, seamless boarding. The reversion to handwritten boarding passes and paper manifests was crude but necessary.

Investing in these manual backups and making sure staff are trained to execute them under pressure is as essential as any other security measure. In the race to digitize, this old-school readiness often gets pushed aside, until it becomes a lifeline.

Experts are trying to find out who’s responsible. Terror law watchdog Jonathan Hall KC says it’s possible state-sponsored hackers could be behind the attack. Places like Heathrow in the UK are quite obvious targets during big political and economic tensions. Figuring out who’s behind attacks like this is always tough, but it shows that important systems like airports are now key targets in global cyber battles.

This incident shows that being ready for cyberattacks isn’t just about building stronger defenses. It means taking care of the entire system – making sure every part, including suppliers, is secure, planning for the worst, and having backup plans that keep important services running no matter what.

The aviation sector might be racing toward a more automated future, but we have to keep in mind that the digital runway isn’t invincible, and resilience must be built in from the ground up.
