Incident Score: Analysis & Impact (AMA1768595116)

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%), supported by evidence indicating exploited exposed management interfaces on customer-owned edge devices and External Remote Services (T1133) with moderate to high confidence (80%), supported by evidence indicating targeted misconfigured VPN concentrators and remote access gateways. Under the Credential Access tactic, the analysis identified Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating harvest credentials to move laterally within victim networks and Unsecured Credentials: Private Keys (T1552.004) with moderate to high confidence (70%), supported by evidence indicating exploited misconfigured network edge devices for credential harvesting. Under the Lateral Movement tactic, the analysis identified Exploitation of Remote Services (T1210) with moderate to high confidence (80%), supported by evidence indicating moved laterally within victim networks after initial access and Remote Services: SSH (T1021.004) with moderate to high confidence (70%), supported by evidence indicating persistent connections to compromised EC2 instances. Under the Persistence tactic, the analysis identified External Remote Services (T1133) with moderate to high confidence (80%), supported by evidence indicating maintained persistent access via misconfigured edge devices and Account Manipulation (T1098) with moderate to high confidence (70%), supported by evidence indicating actor-controlled IPs established persistent connections. Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with moderate confidence (60%), supported by evidence indicating minimizing detection risks by leveraging misconfigurations and Valid Accounts: Cloud Accounts (T1078.004) with moderate to high confidence (70%), supported by evidence indicating used harvested credentials to evade detection. Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating credentials and network access compromised via edge devices. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), supported by evidence indicating persistent connections to actor-controlled IPs suggest data exfiltration. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
