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 moderate to high confidence (70%), with evidence including breach of a live or archived user database, and centralized account infrastructure and Exploit Public-Facing Application (T1190) with moderate confidence (60%), supported by evidence indicating method of the breach remains undisclosed (implied web-facing system). Under the Credential Access tactic, the analysis identified Unsecured Credentials: Credentials in Files (T1552.006) with moderate confidence (50%), supported by evidence indicating breach of a live or archived user database (implied credential storage). Under the Exfiltration tactic, the analysis identified Transfer Data to Cloud Account (T1537) with moderate to high confidence (80%), supported by evidence indicating leaked on the newly launched hacking forum *Breach Stars* and Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), supported by evidence indicating data exfiltration confirmed by *Hackread.com*. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with lower confidence (30%), supported by evidence indicating no evidence of encryption, but data was leaked (implied impact) and Data Destruction (T1485) with lower confidence (20%), supported by evidence indicating no evidence of destruction, but data was exposed. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
