Under the Initial Access tactic, the analysis identified Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating gained initial access via an OpenVPN connection from a trusted external partner, exploiting stolen credentials. Under the Execution tactic, the analysis identified Command and Scripting Interpreter (T1059) with moderate to high confidence (80%), supported by evidence indicating deployed tools like OpenSSH, SoftPerfect Network Scanner, SOCKS5 proxies, and Mimikatz and System Services: Service Execution (T1569.002) with moderate to high confidence (70%), supported by evidence indicating used PsExec/PAExec for widespread ransomware deployment. Under the Persistence tactic, the analysis identified Account Manipulation (T1098) with moderate confidence (60%), supported by evidence indicating harvest passwords, including attempts to breach KeePassXC vaults and External Remote Services (T1133) with moderate to high confidence (80%), supported by evidence indicating openVPN connection from a trusted external partner. Under the Privilege Escalation tactic, the analysis identified Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating exploiting stolen credentials for lateral movement via RDP and SSH. Under the Defense Evasion tactic, the analysis identified Masquerading (T1036) with moderate to high confidence (70%), supported by evidence indicating windows variant requires a SHA-256-validated secret argument to execute, Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (80%), supported by evidence indicating terminates database, backup, virtualization, and browser processes, and Debugger Evasion (T1622) with moderate to high confidence (70%), supported by evidence indicating implements anti-debugging checks (e.g., IsDebuggerPresent). Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with high confidence (90%), supported by evidence indicating deployed Mimikatz to harvest passwords and Credentials from Password Stores (T1555) with moderate to high confidence (80%), supported by evidence indicating attempts to breach KeePassXC vaults. Under the Discovery tactic, the analysis identified Network Service Discovery (T1046) with moderate to high confidence (80%), supported by evidence indicating used SoftPerfect Network Scanner 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 used RDP (Windows) and SSH (Linux) for lateral movement and Remote Services: SSH (T1021.004) with high confidence (90%), supported by evidence indicating used SSH for lateral movement and reverse SSH tunnel for C2. Under the Command and Control tactic, the analysis identified Proxy: Internal Proxy (T1090.001) with moderate to high confidence (80%), supported by evidence indicating used SOCKS5 proxies for C2 communication and Protocol Tunneling (T1572) with high confidence (90%), supported by evidence indicating reverse SSH tunnel facilitated command-and-control communication. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (100%), supported by evidence indicating genieLocker ransomware encrypts files using XChaCha20-Poly1305 AEAD and Inhibit System Recovery (T1490) with moderate to high confidence (80%), supported by evidence indicating terminates backup processes to maximize encryption impact. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
