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 Exploit Public-Facing Application (T1190) with moderate confidence (50%), with evidence including cyberattack on its information systems, and attack vector not disclosed and Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating isolation of potential attack suggests unauthorized access. Under the Impact tactic, the analysis identified Service Stop (T1489) with high confidence (90%), supported by evidence indicating disruption of certain services and management platforms and Account Access Removal (T1531) with moderate to high confidence (70%), supported by evidence indicating isolation operations disrupted services for customers.
