Incident Score: Analysis & Impact (STR1773714231)

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%), with evidence including compromised VPN credentials, and intrusions typically begin with compromised VPN credentials and Exploit Public-Facing Application (T1190) with moderate to high confidence (70%), with evidence including rDP exploitation, and once inside, operators use RDP to navigate manually. Under the Execution tactic, the analysis identified Command and Scripting Interpreter: PowerShell (T1059.001) with high confidence (90%), supported by evidence indicating aI-assisted PowerShell script as part of its wiping toolkit and Windows Management Instrumentation (T1047) with moderate to high confidence (80%), supported by evidence indicating handala Wiper distributed via Group Policy logon scripts (handala.bat). Under the Persistence tactic, the analysis identified Account Manipulation (T1098) with moderate to high confidence (70%), supported by evidence indicating compromised VPN credentials obtained through brute-force attacks and Boot or Logon Autostart Execution: Registry Run Keys / Startup Folder (T1547.001) with moderate to high confidence (80%), supported by evidence indicating group Policy logon scripts (handala.bat) for wiper deployment. Under the Privilege Escalation tactic, the analysis identified Valid Accounts (T1078) with high confidence (90%), with evidence including compromised VPN credentials, and rDP exploitation with attacker-controlled machines. Under the Defense Evasion tactic, the analysis identified Indicator Removal: Clear Windows Event Logs (T1070.001) with moderate confidence (60%), supported by evidence indicating destructive phase employs four simultaneous wiping techniques, Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (70%), supported by evidence indicating veraCrypt abuse to lock drives and prevent recovery, and Masquerading (T1036) with moderate to high confidence (80%), supported by evidence indicating netBird, a legitimate peer-to-peer networking tool, to tunnel traffic. Under the Credential Access tactic, the analysis identified Brute Force (T1110) with moderate to high confidence (80%), supported by evidence indicating compromised VPN credentials obtained through brute-force attacks and Unsecured Credentials: Credentials In Files (T1552.001) with moderate confidence (60%), supported by evidence indicating supply chain breaches for credential access. Under the Lateral Movement tactic, the analysis identified Remote Services: Remote Desktop Protocol (T1021.001) with high confidence (90%), supported by evidence indicating rDP exploitation to navigate manually within victim networks and Account Discovery: Domain Account (T1087.002) with moderate to high confidence (70%), supported by evidence indicating multiple attacker-controlled machines within a single environment. Under the Impact tactic, the analysis identified Data Destruction (T1485) with high confidence (100%), with evidence including permanently erase data, and four simultaneous wiping techniques to maximize damage, Disk Wipe: Disk Structure Wipe (T1561.002) with high confidence (90%), with evidence including corrupting Master Boot Records (MBR), and handala Wiper overwrites files, and Inhibit System Recovery (T1490) with high confidence (90%), with evidence including veraCrypt abuse to lock drives, and delete virtual machines and files over RDP. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
