A sophisticated cyberattack has disrupted operations at three major European airports—Heathrow, Brussels, and Berlin—causing widespread flight cancellations and delays. Cybersecurity leaders say the incident exposes systemic weaknesses in shared aviation technology and underscores the urgent need for stronger supply chain security and compliance with evolving regulations like the NIS2 Directive.

“Simultaneous disruptions at multiple airports demonstrate the fragility of interconnected systems,” said Bernard Montel, EMEA Technical Director at Tenable. “When third-party services are compromised, the effects extend far beyond any single organization. This event validates the regulatory push to address supply chain vulnerabilities proactively.”

Supply Chain Dependencies Under Scrutiny

 

Modern airports depend on a complex ecosystem of vendors for baggage handling, passenger processing, and operational support. According to experts, the attackers appear to have exploited a shared system or service, triggering a cascade of failures across multiple hubs. Montel emphasized that unraveling the full scope of the breach may take months, given the number of interconnected stakeholders involved.

Javvad Malik, Lead Security Awareness Advocate at KnowBe4, stressed the importance of contingency planning:

“Airports and airlines must design for graceful failure. Staff should rehearse manual procedures, ensure offline tools are available, and diversify technology providers to avoid single points of failure.”

Zero Trust and AI Integration Recommended

Darren Guccione, CEO of Keeper Security, believes the attack reflects a deliberate strategy to target high-value, widely used systems. He advocates for zero trust security architectures combined with AI-powered privileged access management to minimize damage when breaches occur.

“Every access request should be verified, every connection monitored, and credentials revoked automatically if a threat is detected,” Guccione said. “AI-driven response mechanisms are now critical for maintaining operational continuity in essential services.”

Strategic Lessons for the Sector

  • Cross-border disruptions reveal the need for coordinated cybersecurity strategies across EU aviation infrastructure.

  • Shared platforms magnify risk, making supply chain security as critical as perimeter defenses.

  • Regulatory compliance under NIS2 must be paired with operational resilience planning and investment in zero trust models.
