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 Exploit Public-Facing Application (T1190) with moderate confidence (50%), supported by evidence indicating attack vector not specified, but ransomware groups often exploit public-facing apps and External Remote Services (T1133) with lower confidence (40%), supported by evidence indicating no specific evidence, but common ransomware entry point. Under the Credential Access tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating ransomware groups often use compromised credentials for access and Brute Force (T1110) with lower confidence (40%), supported by evidence indicating no direct evidence, but common in ransomware attacks. Under the Discovery tactic, the analysis identified File and Directory Discovery (T1083) with moderate to high confidence (70%), supported by evidence indicating 800 GB of data exfiltrated implies extensive discovery of sensitive files and Account Discovery (T1087) with moderate confidence (60%), supported by evidence indicating staff details and customer data accessed suggests account discovery. Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating customer data, financial records, and databases exfiltrated (800 GB) and Data from Network Shared Drive (T1039) with moderate to high confidence (70%), supported by evidence indicating business documents, tax records, and contract details accessed. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating 800 GB of data exfiltrated; threat actor listed victim on dark web leak site and Transfer Data to Cloud Account (T1537) with moderate confidence (50%), supported by evidence indicating no direct evidence, but possible for large-scale exfiltration. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating ransomware note mentions encryption; implied by ransomware strain and Data Destruction (T1485) with lower confidence (30%), supported by evidence indicating no direct evidence, but possible in ransomware attacks. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate confidence (60%), supported by evidence indicating ransomware groups often obfuscate malware to evade detection and Impair Defenses: Disable or Modify Tools (T1562.001) with moderate confidence (50%), supported by evidence indicating ransomware notes warn against modifying/restarting devices. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
