ACI EUROPE has urged airports and technology suppliers to strengthen cyber resilience against emerging AI enabled security threats.

Insight: AI foundations for airport growtht -750x500

ACI EUROPE has issued an open letter warning airports and aviation technology partners about the emergence of advanced “Mythos”-class artificial intelligence cyber capabilities and the growing risks posed to aviation infrastructure.

The organisation stated that airports are operating within an increasingly complex geopolitical environment shaped by persistent cyber threats and hybrid warfare activity.

ACI EUROPE urges stronger aviation cyber resilience measures

According to ACI EUROPE, Mythos-class AI systems are capable of autonomously identifying, linking and exploiting cyber vulnerabilities at unprecedented speed and scale.

The association warned that airport ecosystems are particularly exposed due to the large number of interconnected operators, airlines, ground handlers, industrial systems, cloud services and third-party technology suppliers involved in day-to-day airport operations.

ACI EUROPE stated that vulnerabilities introduced anywhere across the aviation supply chain could potentially create operational consequences extending beyond a single organisation.

The organisation said the emergence of these threats highlights the need for collective cyber resilience across the aviation sector and urged all technology providers and managed service partners supporting airport operations to strengthen mitigation measures without delay.

Recommended actions outlined in the letter include reducing attack surface exposure, reinforcing identity management and zero trust security principles, and implementing risk based vulnerability management processes.

ACI EUROPE also highlighted the importance of stronger software supply chain security and accelerated compliance with the European Union Cyber Resilience Act ahead of its implementation in September 2027.

Additional measures include improved vulnerability disclosure programmes, faster remediation mechanisms, maintenance of Software Bills of Materials and automated defensive security testing.

The organisation also encouraged aviation stakeholders to explore defensive applications of advanced AI technologies to support threat detection and vulnerability remediation.

ACI EUROPE stated that resilience and recovery capabilities remain critical as the aviation industry adapts to an evolving cyber security environment increasingly shaped by AI enabled threats.
