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 unauthorized actor accessed and copied files from the network (implies possible misuse of valid credentials) and Exploit Public-Facing Application (T1190) with moderate confidence (50%), supported by evidence indicating suspicious activity on its computer systems (unspecified vector, but public-facing systems are common targets). Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (95%), supported by evidence indicating unauthorized actor ... copied files from the network between September 18 and 19, 2025. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol (T1048) with high confidence (90%), supported by evidence indicating files copied from the network (implies data staged and exfiltrated via unspecified protocol) and Automated Exfiltration (T1020) with moderate confidence (60%), supported by evidence indicating files copied (suggests automated collection/exfiltration within 24-hour window). Under the Impact tactic, the analysis identified Data from Cloud Storage Object (T1598) with lower confidence (40%), supported by evidence indicating computer systems (potential cloud/on-prem hybrid; PHI/PII often stored in cloud backups) and Data Destruction (T1485) with lower confidence (10%), supported by evidence indicating no ransomware mentioned (low confidence; included due to PHI/PII exposure severity). Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate confidence (50%), supported by evidence indicating unauthorized actor accessed and copied files (possible lateral movement via dumped credentials). Under the Defense Evasion tactic, the analysis identified Indicator Removal on Host (T1070) with moderate confidence (60%), supported by evidence indicating suspicious activity detected on Sept 19 (actor may have cleared logs to delay detection).
