Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Moxa breach identified under incident ID SIEMOXMITHIT1774866497.
The analysis begins with a detailed overview of Moxa's information like the linkedin page: https://www.linkedin.com/company/moxa, the number of followers: 61948, the industry type: Automation Machinery Manufacturing and the number of employees: 1407 employees
After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 760 and after the incident was 755 with a difference of -5 which is could be a good indicator of the severity and impact of the incident.
In the next step of the video, we will analyze in more details the incident and the impact it had on Moxa and their customers.
Polish Power Grid recently reported "Exposed ICS/OT Devices Under Nation-State Threat: Key Findings from Team Cymru’s Research", a noteworthy cybersecurity incident.
Team Cymru’s latest research reveals alarming vulnerabilities in industrial control systems (ICS) and operational technology (OT) environments, highlighting how exposed devices remain prime targets for hostile nation-state actors.
The disruption is felt across the environment, affecting Hitachi RTU560, Moxa NPort and Allen-Bradley ControlLogix.
In response, and began remediation that includes Manual intervention for recovery and Firmware updates.
The case underscores how teams are taking away lessons such as The research underscores a critical gap in ICS/OT security: thousands of devices remain internet-exposed despite best practices advising against direct public access. The persistence of default credentials, unpatched vulnerabilities, and nation-state reconnaissance efforts signals an urgent need for improved IT/OT convergence and proactive threat mitigation, and recommending next steps like Rotate default credentials on all ICS/OT devices, Implement network segmentation to limit exposure and Apply patches for known vulnerabilities (e.g., CVE-2023-3595, CVE-2023-3596).
Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.
The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.
MITRE ATT&CK® Correlation Analysis
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 exploiting Hitachi RTU560 remote terminal units, and internet-exposed web interfaces, Valid Accounts (T1078) with high confidence (95%), with evidence including leveraged default credentials on internet-exposed devices, and unrotated factory-default logins, and External Remote Services (T1133) with moderate to high confidence (80%), supported by evidence indicating thousands of devices remain internet-exposed despite best practices. Under the Execution tactic, the analysis identified Exploitation for Client Execution (T1203) with moderate to high confidence (85%), supported by evidence indicating remote code execution via maliciously crafted CIP messages and Command and Scripting Interpreter (T1059) with moderate to high confidence (70%), supported by evidence indicating uploading corrupted firmware that forced devices into infinite reboot loop. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating gained administrative access via default credentials and Event Triggered Execution (T1546) with moderate to high confidence (70%), supported by evidence indicating compromised modules could manipulate process data, maintain persistence. Under the Privilege Escalation tactic, the analysis identified Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating default credentials provided administrative access. Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (80%), supported by evidence indicating reset devices to factory settings, cutting them off from the network, Indicator Removal: Timestomp (T1070.006) with moderate confidence (60%), supported by evidence indicating reconfigured IP addresses to 127.0.0.1, and Hide Artifacts: Hidden Window (T1564.003) with moderate to high confidence (70%), supported by evidence indicating evade detection potentially leading to catastrophic failures. Under the Credential Access tactic, the analysis identified Brute Force: Password Guessing (T1110.001) with high confidence (90%), supported by evidence indicating default credentials on internet-exposed web interfaces and Valid Accounts (T1078) with high confidence (95%), supported by evidence indicating unrotated factory-default logins. Under the Discovery tactic, the analysis identified Network Service Discovery (T1046) with moderate to high confidence (80%), supported by evidence indicating thousands of devices remain internet-exposed and File and Directory Discovery (T1083) with moderate to high confidence (70%), supported by evidence indicating pivot deeper into OT networks via Moxa networking equipment. Under the Lateral Movement tactic, the analysis identified Exploitation of Remote Services (T1210) with moderate to high confidence (80%), supported by evidence indicating attackers leveraging networking equipment to pivot deeper into OT networks. Under the Impact tactic, the analysis identified Endpoint Denial of Service: OS Exhaustion Flood (T1499.001) with high confidence (90%), supported by evidence indicating infinite reboot loop, rendering devices inoperable, Data Manipulation: Transmitted Data Manipulation (T1565.002) with moderate to high confidence (80%), supported by evidence indicating compromised modules could manipulate process data, and Damage to Property (T0880) with moderate to high confidence (70%), supported by evidence indicating disruptive or destructive attacks on essential services. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
