Under the Initial Access tactic, the analysis identified Exploit Public-Facing Application (T1190) with moderate confidence (60%), supported by evidence indicating hackers disrupted the company’s systems, causing widespread outages and Trusted Relationship (T1199) with moderate to high confidence (80%), supported by evidence indicating conduent, a major provider of government and corporate technology services. Under the Credential Access tactic, the analysis identified Unsecured Credentials (T1552) with moderate to high confidence (70%), supported by evidence indicating processes sensitive data for over 100 million people through healthcare programs and OS Credential Dumping (T1003) with moderate confidence (50%), supported by evidence indicating names, Social Security numbers, medical records compromised. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating stolen information includes names, Social Security numbers, medical records and Data from Information Repositories (T1213) with moderate to high confidence (80%), supported by evidence indicating processes data for over 100 million people through healthcare programs. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating safeway ransomware group claimed responsibility, exfiltrated over 8 terabytes and Transfer Data to Cloud Account (T1537) with moderate confidence (60%), supported by evidence indicating data breach potentially affecting tens of millions of Americans. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with moderate to high confidence (70%), supported by evidence indicating type such as Ransomware, Safeway ransomware group claimed responsibility and Defacement (T1491) with moderate confidence (50%), supported by evidence indicating widespread outages in government services caused by disruption. Under the Defense Evasion tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating processes sensitive data for over 100 million people (trusted access) and Impair Defenses: Disable or Modify Tools (T1562.001) with moderate confidence (60%), supported by evidence indicating widespread outages in government services (system disruption). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
