European Commission Breach Incident Score: Analysis & Impact (EUR1774628727)

In this Rankiteo incident briefing, we review the European Commission breach identified under incident ID EUR1774628727.

The analysis begins with a detailed overview of European Commission's information like the linkedin page: https://www.linkedin.com/company/european-commission, the number of followers: 2433673, the industry type: Government Administration and the number of employees: 41562 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 804 and after the incident was 760 with a difference of -44 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 European Commission and their customers.

European Commission recently reported "EU Commission Cloud Breach: Threat Actor Steals 350GB of Data", a noteworthy cybersecurity incident.

The European Commission is investigating a security breach after a threat actor infiltrated its Amazon cloud infrastructure, gaining access to sensitive employee data.

The disruption is felt across the environment, affecting Amazon cloud infrastructure, internal email server, and exposing 350GB of data, including databases and employee information.

In response, teams activated the incident response plan, and stakeholders are being briefed through Limited public acknowledgment.

The case underscores how Ongoing.

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 Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating at least one account managing the compromised cloud environment was affected and Trusted Relationship (T1199) with moderate to high confidence (70%), supported by evidence indicating amazon cloud infrastructure compromise via managed account. Under the Credential Access tactic, the analysis identified Steal Application Access Token (T1528) with moderate to high confidence (80%), supported by evidence indicating threat actor infiltrated its Amazon cloud infrastructure and Brute Force (T1110) with moderate confidence (50%), supported by evidence indicating no details on initial access method, but cloud account compromise. Under the Persistence tactic, the analysis identified Account Manipulation (T1098) with moderate to high confidence (70%), supported by evidence indicating access to sensitive employee data via cloud account. Under the Collection tactic, the analysis identified Data from Cloud Storage (T1530) with high confidence (90%), supported by evidence indicating 350GB of data including multiple databases exfiltrated from cloud and Data from Information Repositories (T1213) with moderate to high confidence (80%), supported by evidence indicating access to employee information and internal email server. Under the Exfiltration tactic, the analysis identified Transfer Data to Cloud Account (T1537) with high confidence (90%), supported by evidence indicating threat actor exfiltrated over 350GB of data and Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), supported by evidence indicating data exfiltration confirmed, no ransomware involved. Under the Impact tactic, the analysis identified Data Destruction (T1485) with lower confidence (40%), supported by evidence indicating threat actor intends to leak the data online and Defacement (T1491) with lower confidence (30%), supported by evidence indicating potential reputational damage to the European Commission. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
