Case Study
Case Study: Massive Data Breach at Dublin and Cork Airports Exposes Millions of Passengers
📊Incident Overview
Date & Scale: The data breach was identified on October 20, 2025, impacting potentially millions of passengers in the aviation sector.
Perpetrators: The breach has been linked to a vulnerability in systems managed by Collins Aerospace, a third-party supplier responsible for handling sensitive travel information.

🔧Technical Breakdown
The breach occurred due to a poorly secured API (Application Programming Interface) that Collins Aerospace used for data exchange with Dublin and Cork Airports. Attackers exploited this vulnerability to gain unauthorized access to the database containing passenger travel information. The attackers employed automated scripts to probe the API for weaknesses, eventually leading to a successful compromise.
API Vulnerability: Lack of proper authentication and encryption mechanisms allowed attackers to bypass security.
Data Exposure: Once inside, the attackers could execute SQL injection attacks to extract sensitive information from the database.
Third-Party Risk: The breach highlighted the risks associated with third-party suppliers who may not adhere to stringent security protocols.

🔍Root Causes
The incident can be attributed to several root causes:
Inadequate Security Protocols: Collins Aerospace failed to implement robust security measures for their APIs.
Third-Party Dependency: Overreliance on third-party suppliers without sufficient oversight or security assessments.
Lack of Incident Response Plan: Absence of a proactive incident response plan to quickly address vulnerabilities and breaches.
Insufficient Staff Training: Personnel may not have been adequately trained to recognize and mitigate cyber threats.

📚Lessons Learned
To prevent future incidents, the following recommendations should be considered:
Enhance Third-Party Security Evaluations: Implement rigorous security assessments for third-party vendors, focusing on their handling of sensitive data.
Strengthen API Security: Employ strong authentication mechanisms, encryption protocols, and regular vulnerability assessments of APIs.
Develop a Comprehensive Incident Response Plan: Create a detailed response plan that includes immediate steps for containment and communication during a breach.
Invest in Staff Training: Regularly train employees on cybersecurity awareness, including recognizing phishing attempts and handling sensitive information securely.
Implement Continuous Monitoring: Utilize security information and event management (SIEM) systems to monitor network traffic for unusual activities in real-time.
By addressing these vulnerabilities and implementing strategic recommendations, Dublin and Cork Airports can enhance their cybersecurity posture and mitigate the risks associated with future data breaches.
