Full Incident Analysis Transcript

In this Rankiteo incident briefing, we review the VMware breach identified under incident ID VMWSON1768209752.

The analysis begins with a detailed overview of VMware's information like the linkedin page: https://www.linkedin.com/company/vmware, the number of followers: 2049076, the industry type: Software Development and the number of employees: 12343 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 213 and after the incident was 210 with a difference of -3 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 VMware and their customers.

A newly reported cybersecurity incident, "SonicWall VPN Exploitation Leading to VMware ESXi Targeting", has drawn attention.

Threat actors exploited vulnerabilities in SonicWall VPN appliances to gain initial access and target VMware ESXi systems.

The disruption is felt across the environment, affecting VMware ESXi systems.

Formal response steps have not been shared publicly yet.

The case underscores how teams are taking away lessons such as Timely detection and response are critical in preventing ransomware deployment. The incident underscores the persistent threat posed by skilled and resourceful actors, and recommending next steps like Organizations should implement rigorous cybersecurity measures and maintain continuous vigilance.

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%), supported by evidence indicating exploited vulnerabilities in SonicWall VPN appliances to gain initial access and External Remote Services (T1133) with moderate to high confidence (80%), supported by evidence indicating compromised VPNs as an entry point to bypass security controls. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating exploited known loopholes in SonicWall VPN (implied valid account usage). Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate confidence (60%), supported by evidence indicating targeted VMware ESXi systems (high-privilege infrastructure). Under the Defense Evasion tactic, the analysis identified Valid Accounts: Cloud Accounts (T1078.004) with moderate to high confidence (70%), supported by evidence indicating bypassed security controls via compromised VPN (implied valid credentials) and Impair Defenses: Disable or Modify System Firewall (T1562.004) with moderate confidence (50%), supported by evidence indicating exploited SonicWall VPN vulnerabilities (may include firewall bypass). Under the Lateral Movement tactic, the analysis identified Exploitation of Remote Services (T1210) with moderate to high confidence (80%), supported by evidence indicating moved from SonicWall VPN to VMware ESXi systems. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with moderate confidence (60%), supported by evidence indicating attack was interrupted before ransomware deployment (implied intent). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
