Under the Execution tactic, the analysis identified User Execution: Malicious File (T1204.002) with moderate to high confidence (70%), supported by evidence indicating systems disrupted by ransomware on July 15, 2025 and Command and Scripting Interpreter (T1059) with moderate confidence (60%), supported by evidence indicating rhysida ransomware strain involved in data encryption. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating unauthorized access occurred over multiple days (July 11-14, 2025). Under the Privilege Escalation tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating access to sensitive medical and personal data (e.g., SSNs, medical records). Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate to high confidence (70%), supported by evidence indicating rhysida ransomware strain used for data encryption and Execution Guardrails (T1480) with moderate confidence (50%), supported by evidence indicating ransomware attack detected only after systems were disrupted. Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate confidence (60%), supported by evidence indicating exposed Social Security numbers, financial account details and Unsecured Credentials: Credentials In Files (T1552.001) with moderate confidence (50%), supported by evidence indicating medical records and health insurance data compromised. Under the Discovery tactic, the analysis identified Account Discovery (T1087) with moderate confidence (60%), supported by evidence indicating 337,917 records exposed, including PII and medical data and File and Directory Discovery (T1083) with moderate to high confidence (70%), supported by evidence indicating data exfiltration and encryption of sensitive files. Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating names, SSNs, medical records, financial details compromised and Data from Network Shared Drive (T1039) with moderate to high confidence (70%), supported by evidence indicating large-scale breach of 337,917 patient records. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating rhysida demanded ransom for stolen data (10 bitcoins, ~$1.15M) and Exfiltration Over Web Service (T1567) with moderate confidence (60%), supported by evidence indicating raaS group likely used command-and-control infrastructure. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating systems disrupted by ransomware on July 15, 2025, Defacement (T1491) with moderate confidence (50%), supported by evidence indicating public disclosure of breach and ransom demand, and Data Destruction (T1485) with lower confidence (40%), supported by evidence indicating potential disruption to hospital operations (appointments, records). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
