Incident Score: Analysis & Impact (NSC1775824076)

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 lower confidence (40%), supported by evidence indicating potential weaknesses in the NSCC’s internal network isolation and Valid Accounts (T1078) with moderate confidence (50%), supported by evidence indicating exfiltrated over six months via a botnet (implied persistence). Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating exfiltrated over six months via a botnet (long-term access) and Server Software Component (T1505) with lower confidence (30%), supported by evidence indicating botnet used for exfiltration (implied compromised systems). Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (80%), supported by evidence indicating disabled/unmonitored logs (post-incident analysis root cause) and Disabling Security Tools (T1089) with moderate to high confidence (70%), supported by evidence indicating severe network segmentation flaws (implied evasion of detection). Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate confidence (50%), supported by evidence indicating botnet used for exfiltration (implied credential compromise). Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating 10 petabytes of sensitive files...classified documents, schematics and Data from Information Repositories (T1213) with moderate to high confidence (80%), supported by evidence indicating military equipment renderings, schematics for missiles and bombs. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating exfiltrated over six months via a botnet (10 petabytes) and Automated Exfiltration (T1020) with moderate to high confidence (70%), supported by evidence indicating botnet used for exfiltration (automated transfer). Under the Impact tactic, the analysis identified Defacement (T1491) with lower confidence (30%), supported by evidence indicating anonymous source *FlamingChina* leaked files online (public disclosure). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
