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%), with evidence including rhysida RaaS operation targeting healthcare, and likely exploitation of weak credentials and Exploit Public-Facing Application (T1190) with moderate confidence (60%), with evidence including healthcare sector targeted by Rhysida, and no specific vector disclosed. Under the Execution tactic, the analysis identified User Execution: Malicious File (T1204.002) with moderate to high confidence (80%), supported by evidence indicating ransomware attack implies malicious file execution. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating raaS operations often maintain access via valid accounts. Under the Privilege Escalation tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating likely abuse of privileged accounts for ransomware deployment. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate to high confidence (80%), supported by evidence indicating ransomware encryption of data to evade detection and Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (70%), supported by evidence indicating common ransomware tactic to disable security tools. Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate confidence (60%), supported by evidence indicating raaS operations often dump credentials for lateral movement. Under the Discovery tactic, the analysis identified Account Discovery (T1087) with moderate to high confidence (70%), supported by evidence indicating likely enumeration of accounts for targeted data exfiltration and File and Directory Discovery (T1083) with moderate to high confidence (80%), supported by evidence indicating medical records and pathology reports targeted. Under the Lateral Movement tactic, the analysis identified Remote Services: Remote Desktop Protocol (T1021.001) with moderate to high confidence (70%), supported by evidence indicating common RaaS lateral movement method. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating patient data, medical records, and pathology reports exfiltrated. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating data offered for sale on dark web extortion site. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (100%), supported by evidence indicating ransomware encryption of data confirmed and Data Destruction (T1485) with moderate to high confidence (70%), supported by evidence indicating potential data destruction if ransom unpaid. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
