Full Incident Analysis Transcript

In this Rankiteo incident briefing, we review the Health-ISAC breach identified under incident ID HEA1772670272.

The analysis begins with a detailed overview of Health-ISAC's information like the linkedin page: https://www.linkedin.com/company/health-isac, the number of followers: 12511, the industry type: Computer and Network Security and the number of employees: 79 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 581 and after the incident was 560 with a difference of -21 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 Health-ISAC and their customers.

U.S. healthcare organizations recently reported "Health-ISAC Warns U.S. Healthcare Sector of DDoS Threats Amid Iran Tensions", a noteworthy cybersecurity incident.

The Health Information Sharing and Analysis Center (Health-ISAC) has issued a warning to U.S.

The disruption is felt across the environment, affecting Clinical websites, patient portals, VPNs, internet-exposed IoT devices.

In response, moved swiftly to contain the threat with measures like Enhancing DDoS protections, hardening internet-facing systems (VPNs, remote access points), identity security, and began remediation that includes Rehearsing downtime and incident-response procedures.

The case underscores how teams are taking away lessons such as Historical patterns show increased DDoS activity during geopolitical conflicts; even short-lived disruptions can severely impact operations, and recommending next steps like Enhance DDoS protections by working with ISPs, CDNs, and cloud providers, Harden internet-facing systems, particularly VPNs and remote access points, with a focus on identity security and Rehearse downtime and incident-response procedures to ensure continuity of critical clinical services, with advisories going out to stakeholders covering Health-ISAC warning to U.S. healthcare organizations.

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 moderate confidence (60%), supported by evidence indicating public-facing systems including clinical websites, patient portals, VPNs and External Remote Services (T1133) with moderate to high confidence (70%), supported by evidence indicating vPNs and remote access points are particularly vulnerable. Under the Impact tactic, the analysis identified Network Denial of Service (T1498) with high confidence (90%), with evidence including potential distributed denial-of-service (DDoS) attacks, and blocking access to electronic health records (EHRs) and Endpoint Denial of Service: Application or System Exploitation (T1499.004) with moderate to high confidence (70%), supported by evidence indicating dDoS disruptions can severely impact operations like EHR access. Under the Defense Evasion tactic, the analysis identified Network Denial of Service (T1498) with moderate confidence (50%), supported by evidence indicating dDoS attacks may serve as a distraction for other malicious activities. Under the Reconnaissance tactic, the analysis identified Active Scanning (T1595) with moderate confidence (60%), supported by evidence indicating historical patterns show increased DDoS activity during geopolitical conflicts. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
