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 network access detected on May 29, 2025 and Exploit Public-Facing Application (T1190) with moderate confidence (50%), supported by evidence indicating hacking-related data breach; vulnerability exploited not specified. Under the Credential Access tactic, the analysis identified Brute Force (T1110) with moderate confidence (60%), supported by evidence indicating unauthorized access implies possible credential compromise and Unsecured Credentials (T1552) with moderate confidence (50%), supported by evidence indicating no specific evidence, but common in healthcare breaches. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating files exfiltrated containing PHI; data exfiltration confirmed and Transfer Data to Cloud Account (T1537) with lower confidence (40%), supported by evidence indicating no direct evidence, but possible in modern breaches. Under the Defense Evasion tactic, the analysis identified Indicator Removal (T1070) with moderate to high confidence (80%), supported by evidence indicating affected systems were wiped and rebuilt post-incident and Disable or Modify Tools (T1562.001) with moderate confidence (50%), supported by evidence indicating additional security measures implemented post-breach. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
