MITRE ATT&CK® Correlation Analysis

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 External Remote Services (T1133) with high confidence (90%), supported by evidence indicating attack primarily targeted the county’s email system, likely compromised through a remote login vulnerability and Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating remote login vulnerability exacerbated by increased remote work during the pandemic. Under the Execution tactic, the analysis identified User Execution: Malicious File (T1204.002) with moderate to high confidence (70%), supported by evidence indicating ransomware attack locking roughly half of its 400 government computers. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (95%), with evidence including ransomware encrypted data on affected systems, and locking roughly half of its 400 government computers. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate confidence (60%), supported by evidence indicating ransomware attack (type/strain not disclosed) and Virtualization/Sandbox Evasion (T1497) with moderate confidence (50%), supported by evidence indicating attackers based in Hong Kong (geographic evasion potential). Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with lower confidence (40%), supported by evidence indicating attackers demanded ransom ($90,000), implying potential data exfiltration. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
