Incident Score: Analysis & Impact (TP-1775679846)

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 high confidence (90%), with evidence including exploitation of SOHO routers (DHCP/DNS manipulation), and cVE-2023-50224, an unauthenticated flaw allowing credential theft. Under the Persistence tactic, the analysis identified Pre-OS Boot: ROMMONkit (T1542.004) with moderate to high confidence (70%), supported by evidence indicating rewrite the router’s DHCP DNS settings, replacing primary DNS with malicious IP and Server Software Component: Transport Agent (T1505.002) with moderate confidence (60%), supported by evidence indicating deploys malicious DNS resolvers on virtual private servers (VPS). Under the Credential Access tactic, the analysis identified Adversary-in-the-Middle: ARP Poisoning (T1557.002) with high confidence (90%), supported by evidence indicating redirect network traffic through attacker-controlled servers (AitM infrastructure), Adversary-in-the-Middle (T1557) with high confidence (90%), supported by evidence indicating traffic rerouted to adversary-in-the-middle (AitM) infrastructure for credential theft, and Steal Application Access Token (T1528) with moderate to high confidence (80%), supported by evidence indicating theft of passwords and authentication tokens from web and email services. Under the Collection tactic, the analysis identified Data from Information Repositories (T1213) with moderate to high confidence (80%), supported by evidence indicating targeted domains (e.g., Outlook, Office 365, Microsoft authentication services). Under the Command and Control tactic, the analysis identified Dynamic Resolution: Domain Generation Algorithms (T1568.002) with moderate confidence (60%), supported by evidence indicating malicious DNS resolvers on VPS redirect traffic to attacker-controlled servers and Proxy: External Proxy (T1090.002) with moderate to high confidence (80%), supported by evidence indicating redirect network traffic through attacker-controlled servers. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating data exfiltration such as Yes (redirected to attacker-controlled servers). Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (70%), supported by evidence indicating alters compromised routers to direct traffic to malicious DNS while preserving original as fallback and Valid Accounts (T1078) with moderate confidence (50%), supported by evidence indicating stolen credentials (passwords, authentication tokens) may enable further access. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
