Iberia, Spain's flag carrier, confirmed being impacted by a third-party breach after a threat actor claimed to have stolen 77 GB of its data.

The disruption is felt across the environment, and exposing 77 GB.

Formal response steps have not been shared publicly yet.

Overall, the incident is a reminder of why proactive monitoring and strong governance matter.

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%), with evidence including third-party data breach, and external vendor systems as attack vector. Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (85%), supported by evidence indicating 77 GB of its sensitive data exfiltrated. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol: Exfiltration Over Unencrypted/Obfuscated Non-C2 Protocol (T1048.003) with moderate to high confidence (80%), with evidence including threat actor claimed to have exfiltrated 77 GB, and no specifics on encryption. Under the Impact tactic, the analysis identified Data Destruction (T1485) with moderate to high confidence (70%), supported by evidence indicating significant data leak with possible reputational, financial, and regulatory repercussions and Data Encrypted for Impact (T1486) with lower confidence (30%), supported by evidence indicating no explicit ransomware mention, but data leak implies potential dual-use (exfil + encryption). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
