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 allegedly infiltrating China’s National Supercomputing Center in Tianjin and Valid Accounts (T1078) with moderate to high confidence (70%), with evidence including went undetected for months, and supports over 6,000 institutional users. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (80%), with evidence including went undetected for months, and high-performance computing environment access. Under the Privilege Escalation tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating classified research tied to aerospace engineering, military systems. Under the Defense Evasion tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (80%), with evidence including went undetected for months, and high-performance computing environment and Hide Artifacts (T1564) with moderate confidence (60%), supported by evidence indicating breach went undetected for months. Under the Credential Access tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (80%), with evidence including supports over 6,000 institutional users, and high-value targets accessed. Under the Discovery tactic, the analysis identified File and Directory Discovery (T1083) with high confidence (90%), with evidence including 10 petabytes of sensitive data exfiltrated, and technical schematics, advanced simulations. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), with evidence including 10 petabytes of sensitive data exfiltrated, and classified documents marked secret and Data from Network Shared Drive (T1039) with moderate to high confidence (80%), supported by evidence indicating national Supercomputing Center supports 6,000+ institutional users. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), with evidence including 10 petabytes of data exfiltrated, and data surfaced on Telegram and Exfiltration Over Web Service (T1567) with moderate to high confidence (80%), supported by evidence indicating leaked data first surfaced on Telegram. Under the Impact tactic, the analysis identified Defacement (T1491) with lower confidence (40%), supported by evidence indicating data breach publicly disclosed via Telegram and Account Access Removal (T1531) with lower confidence (30%), supported by evidence indicating potential compromise of national security research. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
