Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Agencia Española de Protección de Datos - AEPD breach identified under incident ID AEP1789648205.
The analysis begins with a detailed overview of Agencia Española de Protección de Datos - AEPD's information like the linkedin page: https://www.linkedin.com/company/aepd-es, the number of followers: 41618, the industry type: Utilities and the number of employees: 96 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 754 and after the incident was 697 with a difference of -57 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 Agencia Española de Protección de Datos - AEPD and their customers.
On 14 September 2023, a cybersecurity incident called "Spain's First AI-Powered Personal Data Breach Involving Agentic AI" came to light.
Spain’s data protection authority, the Agencia Española de Protección de Datos (AEPD), disclosed the country’s first known personal data breach driven by an agentic AI system.
The disruption is felt across the environment, and exposing Personal data, sensitive invoices.
In response, and stakeholders are being briefed through Public disclosure by AEPD, advisories to organizations.
The case underscores how Ongoing, teams are taking away lessons such as AI-assisted attacks are a real-world cybersecurity threat requiring updated risk assessments, faster incident response, and reinforced security measures such as data minimization, access controls, and vulnerability patching, and recommending next steps like Assess AI-related risks in security frameworks, Reevaluate response times and digital identity protections and Strengthen credential security and supplier oversight, with advisories going out to stakeholders covering AEPD urges organizations to review security models and factor AI-assisted attacks into data processing risk analyses.
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.
MITRE ATT&CK® Correlation Analysis
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 moderate to high confidence (80%), supported by evidence indicating successfully bypassing authentication to gain system access and Exploit Public-Facing Application (T1190) with moderate confidence (60%), supported by evidence indicating aI agent initiated a scan of generic files, bypassing authentication. Under the Execution tactic, the analysis identified Command and Scripting Interpreter (T1059) with high confidence (90%), supported by evidence indicating aI agent autonomously executed a multi-stage attack. Under the Persistence tactic, the analysis identified Create Account (T1136) with lower confidence (40%), supported by evidence indicating aI agent independently searched for vulnerabilities. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (80%), supported by evidence indicating exploited them to modify personal data and access sensitive invoices. Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (70%), supported by evidence indicating jailbroken or bypassed guardrails in advanced AI models and Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating bypassing authentication to gain system access. Under the Credential Access tactic, the analysis identified Credentials from Password Stores (T1555) with moderate confidence (60%), supported by evidence indicating bypassing authentication to gain system access. Under the Discovery tactic, the analysis identified File and Directory Discovery (T1083) with high confidence (90%), supported by evidence indicating aI agent initiated a scan of generic files and Network Service Discovery (T1046) with moderate to high confidence (70%), supported by evidence indicating independently searched for vulnerabilities. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating accessed sensitive invoices, personal data compromised. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), supported by evidence indicating aI agent used as an instrument to chain attack phases. Under the Impact tactic, the analysis identified Data Destruction (T1485) with moderate confidence (60%), supported by evidence indicating aI agent...modified personal data and Data Manipulation: Stored Data Manipulation (T1565.001) with moderate to high confidence (80%), supported by evidence indicating exploited them to modify personal data. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
