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 Phishing (T1566) with high confidence (95%), with evidence including sophisticated Phishing Kit Targets European Banks, Payment Services, and highly sophisticated phishing kit has emerged, Phishing: Spearphishing Attachment (T1566.001) with moderate to high confidence (70%), supported by evidence indicating highly targeted campaigns with greater precision, and Phishing: Spearphishing Link (T1566.002) with moderate to high confidence (70%), supported by evidence indicating increasingly easy to execute and more challenging to identify. Under the Credential Access tactic, the analysis identified Brute Force (T1110) with moderate confidence (60%), supported by evidence indicating phishing kit designed to compromise major European financial institutions and Modify Authentication Process (T1556) with moderate confidence (50%), supported by evidence indicating advanced capabilities enable cybercriminals to execute highly targeted campaigns. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), with evidence including identity theft risk such as High, and payment information risk such as High. Under the Defense Evasion tactic, the analysis identified Masquerading (T1036) with moderate to high confidence (80%), supported by evidence indicating increasing the difficulty of detection for both individuals and organizations and Impair Defenses: Disable or Modify Tools (T1562.001) with moderate confidence (60%), supported by evidence indicating refine their methods to exploit vulnerabilities in digital financial ecosystems. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
