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%), supported by evidence indicating internal employee records suggests compromise via legitimate credentials or insider access. Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (85%), supported by evidence indicating personally identifiable information (PII) (SSNs, financial records) exposed from employee systems. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol (T1048) with moderate to high confidence (75%), supported by evidence indicating breach focused on internal employee records implies data was extracted (method unspecified). Under the Impact tactic, the analysis identified Spearphishing for Data (T1598.003) with moderate confidence (60%), supported by evidence indicating identity theft or fraud risk suggests PII may be used for follow-on phishing/credential theft and Legal Consequences (T1659) with high confidence (95%), supported by evidence indicating proposed class-action lawsuit and legal liabilities from the breach. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
