Under the Execution tactic, the analysis identified Command and Scripting Interpreter: Windows Command Shell (T1059.003) with moderate to high confidence (80%), supported by evidence indicating aSPX web shells (e.g., key.aspx, log.aspx) served as C2 points and Exploitation for Client Execution (T1203) with moderate to high confidence (70%), supported by evidence indicating dLL sideloading chain abusing LogMeIn Hamachi service. Under the Persistence tactic, the analysis identified Server Software Component: Web Shell (T1505.003) with high confidence (90%), supported by evidence indicating deployed ASPX web shells (key.aspx, log.aspx) for persistence, Create or Modify System Process: Windows Service (T1543.003) with moderate to high confidence (70%), supported by evidence indicating dLL sideloading chain abused LogMeIn Hamachi service, and Exploitation for Privilege Escalation (T1068) with moderate confidence (60%), supported by evidence indicating kernel-mode driver (vmflt.sys) for rootkit-like persistence. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (80%), supported by evidence indicating kernel-mode driver (vmflt.sys) for rootkit-like persistence and Valid Accounts: Domain Accounts (T1078.002) with high confidence (90%), supported by evidence indicating stolen domain admin credentials used for lateral movement. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with high confidence (90%), supported by evidence indicating custom XOR decryption and PRNG-based obfuscation in Deed RAT, Masquerading: Masquerade Task or Service (T1036.004) with moderate to high confidence (80%), supported by evidence indicating dLL sideloading chain abused LogMeIn Hamachi service, and Impair Defenses: Disable or Modify Tools (T1562.001) with moderate confidence (60%), supported by evidence indicating anti-analysis techniques to evade detection. Under the Credential Access tactic, the analysis identified OS Credential Dumping: Security Account Manager (T1003.002) with moderate to high confidence (70%), supported by evidence indicating stolen domain admin credentials used for lateral movement. Under the Discovery tactic, the analysis identified Account Discovery: Domain Account (T1087.002) with moderate to high confidence (80%), supported by evidence indicating lateral movement relied on RDP with stolen domain admin credentials and Network Service Discovery (T1046) with moderate to high confidence (70%), supported by evidence indicating impacket-based tools (atexec, smbexec) used for lateral movement. Under the Lateral Movement tactic, the analysis identified Remote Services: Remote Desktop Protocol (T1021.001) with high confidence (90%), supported by evidence indicating lateral movement relied on RDP with stolen domain admin credentials and Lateral Tool Transfer (T1570) with moderate to high confidence (80%), supported by evidence indicating impacket-based tools (atexec, smbexec) used for lateral movement. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating strategic intelligence on European energy flows compromised. Under the Command and Control tactic, the analysis identified Application Layer Protocol: Web Protocols (T1071.001) with high confidence (90%), supported by evidence indicating aSPX web shells served as command-and-control (C2) points and Ingress Tool Transfer (T1105) with moderate to high confidence (80%), supported by evidence indicating deed RAT deployed via DLL sideloading chain. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating data exfiltration confirmed in espionage campaign. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
