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 Exploit Public-Facing Application (T1190) with moderate confidence (50%), supported by evidence indicating attack vector, vulnerability exploited details not disclosed and External Remote Services (T1133) with lower confidence (40%), supported by evidence indicating medical clinic network compromised, attack vector unclear. Under the Execution tactic, the analysis identified User Execution: Malicious File (T1204.002) with moderate confidence (60%), supported by evidence indicating genesis employs malware that steals data and encrypts systems. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (50%), supported by evidence indicating attackers maintained access to exfiltrate 70 GB of data. Under the Privilege Escalation tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (50%), supported by evidence indicating access to medical, operational, and financial data suggests elevated privileges. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate confidence (60%), supported by evidence indicating genesis ransomware employs malware for encryption and exfiltration and Impair Defenses: Disable or Modify Tools (T1562.001) with lower confidence (40%), supported by evidence indicating disrupted critical systems, reverted to manual record-keeping. Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate confidence (50%), supported by evidence indicating access to sensitive patient data suggests credential compromise. Under the Discovery tactic, the analysis identified Account Discovery (T1087) with moderate confidence (60%), supported by evidence indicating compromised names, medical records, addresses, phone numbers and File and Directory Discovery (T1083) with moderate to high confidence (70%), supported by evidence indicating exfiltrated 70 GB of medical, operational, and financial data. Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating 70 GB of medical, operational, and financial data exfiltrated and Data from Network Shared Drive (T1039) with moderate to high confidence (70%), supported by evidence indicating medical clinic network data compromised. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating 70 GB of data exfiltrated by Genesis ransomware group. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating genesis employs malware that encrypts systems for extortion and Inhibit System Recovery (T1490) with moderate confidence (60%), supported by evidence indicating disrupted critical systems, canceled appointments, diverted patients. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
