Airports hacked: How to prevent similar breaches

Four airports breached through PA systems this week. One passenger asked: "If they hacked the paging system, what else are they tunneling into?" That's the question every critical infrastructure operator should be asking right now.

Critical authentication vulnerabilities reported in Radiometrics VizAir aviation weather system CISA disclosed three critical vulnerabilities (CVE-2025-61945, CVE-2025-54863, CVE-2025-61956,) in Radiometrics VizAir aviation weather monitoring systems that allow unauthenticated remote attackers to access admin panels, manipulate weather data, and alter runway configurations, potentially causing catastrophic flight safety consequences. If you use Radiometrics VizAir aviation weather monitoring systems, verify with Radiometrics that your system received the automatic security updates that fix three maximum-severity flaws. And make sure that your systems are isolated from the internet and accessible only from trusted networks. #cybersecurity #infosec #advisory #vulnerability Read More: https://lnkd.in/d9iXst5t

Cyber Strategy Meets Operational Continuity In the latest airport disruption, technology failure wasn’t the only problem — readiness and contingency planning were tested. CISOs must bridge the gap between cyber controls and operational impact: ��� Map dependencies across the business-critical chain • Scenario-test for non-IT outcomes (flight disruption, supply chain stoppages) #CISO #CyberStrategy #IncidentResponse #DirectorsCyber

The $161 Million Lesson: The True Cost of Operational Disruption (JLR, Co-op Case Studies) Recent attacks underline that the biggest threat is not data loss, but operational collapse. The UK's Co-op revealed a cyber attack cost them $161 million in lost profit due to operational disruption that affected food availability and required systems to be temporarily shut down. Similarly, attacks on Jaguar Land Rover's production systems halted factories for weeks. For aviation, where time is measured in passenger safety and millions of Euros, the risk is exponentially higher. Operational resilience must be the priority. This means moving beyond firewalls to securing the entire supply chain and the core Operational Technology (OT) that runs baggage, refueling, and navigation systems. A resilient operation is one that can maintain service even during a major breach. Quantify your operational risk before an attack forces you to.

🚨 Delhi Airport Incident: A Wake-Up Call for Critical Infrastructure Security ✈️🔐 This week’s disruption at Delhi IGI Airport, where the Flight-Plan Messaging System (AMSS) suffered a major outage causing widespread delays, highlights an important lesson for all of us in cybersecurity. While officials have stated there is no confirmed cyberattack, the combination of a critical system failure and reports of possible GPS spoofing activity shows how vulnerable modern aviation infrastructure can be to both technical glitches and cyber-threat vectors. ✅ Key Takeaways for Cybersecurity Teams: • Critical infrastructure must be built with redundancy and resilience. • Continuous monitoring for threats like GPS spoofing, signal interference, and system anomalies is essential. • Manual fallback procedures are not optional — they are part of cyber-resilience. • Even a small malfunction can lead to nationwide operational impact. As cybersecurity professionals, incidents like these remind us that security + reliability = safety. We must stay proactive, vigilant, and ready to respond. #CyberSecurity #AviationSecurity #CriticalInfrastructure #GPSpoofing #DelhiAirport #CyberAwareness

Ransomware Hits European Airports—Is Your Business Prepared to Recover? The recent ransomware attack on Collins Aerospace caused widespread disruption across European airports, revealing how vulnerable even the most critical systems can be. Heathrow, Berlin, and Brussels were forced into manual operations, highlighting the importance of fallback procedures. Cybercriminals are becoming bolder, targeting high-profile systems for maximum impact. Recovery isn’t just about restoring data; it’s about restoring trust and operations. Two key steps to take now: • Implement robust backup systems: Ensure rapid recovery with off-site and immutable backups. • Run incident response drills: Test your team’s ability to respond under pressure. October is Cybersecurity Awareness Month—let’s make resilience a priority. Need help building a recovery plan?

🚆 Use Case: Protecting National Railway Networks from Cyberattacks Modern railway systems rely on interconnected IT and OT networks for ticketing, scheduling, signaling, and passenger data — making them prime targets for cyberattacks. A single breach can disrupt train operations, steal customer data, or even threaten passenger safety. Traditional firewalls allow two-way communication and can be bypassed through ransomware, zero-day exploits, or compromised booking portals. Incident: https://lnkd.in/gDeMQ6dQ AliensGuard Data Diode ensures one-way, hardware-enforced communication, allowing data to flow only from operational systems (OT) to business systems (IT) — never back in. This makes external hacking physically impossible. Key Benefits: ✅ Zero external threat surface ✅ Passenger and operational data fully secured ✅ Guaranteed uptime and safety ✅ Compliance with transport cybersecurity standards Example: If hackers breach the public booking system, the attack cannot spread to train control networks. With AliensGuard Data Diode, railway operations continue safely, customer trust remains intact, and critical infrastructure stays protected.

Cybersecurity is now mission-critical for the maritime industry. The U.S. Coast Guard’s new cybersecurity rule makes protection of IT and OT systems a legal requirement for all vessels and Maritime Transportation System (MTS) facilities. From ports and energy terminals to offshore platforms, compliance is mandatory and essential to maintaining safety, continuity, and trust. At Xage Security, we’re helping maritime operators navigate this new regulatory landscape with our Xage Fabric Platform. Built for the realities of maritime operations, including denied, disrupted, intermittent, or limited (DDIL) environments, Xage provides unified access control, network segmentation, encryption, and continuous protection across IT and OT assets. With the Coast Guard’s new requirements taking effect soon, now is the time to strengthen your cybersecurity posture and ensure full compliance.

The world’s seas are becoming battlegrounds for cyber threats. Nation-state attackers aren’t just after data—they’re targeting vessels, ports, and shipyards to disrupt operations and seize strategic advantage. As navigation, propulsion, and cargo systems grow more connected, cybersecurity has become a frontline concern for maritime safety and the continuity of global trade. Regulations like IMO, TSA, and IEC 62443 are driving critical upgrades—but meeting compliance is just the starting point. Lasting resilience depends on total visibility, robust control, and trust at every point of access. For maritime leaders, protecting your operations starts with securing identity and access everywhere it matters.
