Brussels Airport Breach Incident Score: Analysis & Impact (BRU3230732111025)

In this Rankiteo incident briefing, we review the Brussels Airport breach identified under incident ID BRU3230732111025.

The analysis begins with a detailed overview of Brussels Airport's information like the linkedin page: https://www.linkedin.com/company/brussels-airport-company, the number of followers: 77794, the industry type: Airlines and Aviation and the number of employees: 1378 employees

After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 743 and after the incident was 723 with a difference of -20 which is could be a good indicator of the severity and impact of the incident.

In the next step of the video, we will analyze in more details the incident and the impact it had on Brussels Airport and their customers.

Brussels Airport recently reported "Cyberattaque chez un fournisseur de Brussels Airport entraînant des retards et annulations de vols", a noteworthy cybersecurity incident.

Brussels Airport a subi une cyberattaque chez un fournisseur, perturbant les systèmes d'enregistrement et d'embarquement.

The disruption is felt across the environment, affecting Systèmes d'enregistrement and Systèmes d'embarquement.

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like Systèmes alternatifs d'enregistrement et d'embarquement déployés en urgence, and began remediation that includes Installation, configuration et tests accélérés des nouveaux équipements/logiciels sur 500 postes de travail, while recovery efforts such as Transition progressive vers le nouveau système pour toutes les compagnies aériennes; maintien des systèmes alternatifs pendant la phase de transition continue, and stakeholders are being briefed through Communiqué de presse pour informer du contrôle de la situation et des mesures prises.

The case underscores how En cours (déploiement des correctifs et transition progressive), with advisories going out to stakeholders covering Communiqués publics sur l'état des opérations et les mesures de récupération.

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.

Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Supply Chain Compromise: Third-party Software (T1195.002) with high confidence (95%), supported by evidence indicating cyberattack targeting one of its third-party suppliers, severely disrupting its check-in and boarding systems. Under the Impact tactic, the analysis identified Endpoint Denial of Service: Application Exhaustion Flood (T1499.002) with moderate to high confidence (85%), supported by evidence indicating disrupting its check-in and boarding systems... caused widespread flight delays and cancellations for at least ten days and Endpoint Denial of Service: Application or System Exploitation (T1499.004) with moderate to high confidence (80%), supported by evidence indicating severely disrupting its check-in and boarding systems... only one-third of the 500 workstations were operational. Under the Defense Evasion tactic, the analysis identified Indicator Removal: File Deletion (T1070.004) with moderate confidence (60%), supported by evidence indicating no further cancellations (suggests attacker may have removed traces post-disruption). Under the Lateral Movement tactic, the analysis identified Remote Services: SMB/Windows Admin Shares (T1021.002) with moderate to high confidence (70%), supported by evidence indicating 500 workstations... remaining relied on temporary solutions (implies lateral spread across internal systems). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
