Full Incident Analysis Transcript

In this Rankiteo incident briefing, we review the American Hospital Association breach identified under incident ID AME1781270254.

The analysis begins with a detailed overview of American Hospital Association's information like the linkedin page: https://www.linkedin.com/company/american-hospital-association, the number of followers: 116379, the industry type: Hospitals and Health Care and the number of employees: 1604 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 681 and after the incident was 548 with a difference of -133 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 American Hospital Association and their customers.

A newly reported cybersecurity incident, "Coordinated Ryuk Ransomware Attack Disrupts U.S. Hospitals Amid Pandemic", has drawn attention.

Over a 24-hour period starting Monday, six U.S.

The disruption is felt across the environment, affecting Hospital systems, and exposing Critical data encrypted.

Formal response steps have not been shared publicly yet.

The case underscores how Ongoing.

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 targeted Ryuk ransomware attack...exploiting vulnerabilities in systems and External Remote Services (T1133) with moderate confidence (50%), supported by evidence indicating coordinated effort to maximize disruption and financial gain. Under the Execution tactic, the analysis identified User Execution: Malicious File (T1204.002) with moderate to high confidence (70%), supported by evidence indicating ryuk ransomware, which encrypts critical data. Under the Persistence tactic, the analysis identified Scheduled Task/Job: Scheduled Task (T1053.005) with moderate confidence (50%), supported by evidence indicating coordinated Ryuk ransomware attack over a 24-hour period. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate confidence (60%), supported by evidence indicating ryuk ransomware...encrypts critical data, halt noncritical surgeries. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate to high confidence (70%), supported by evidence indicating ryuk ransomware, known for its high-impact extortion tactics and Execution Guardrails (T1480) with moderate confidence (50%), supported by evidence indicating targeted Ryuk ransomware attack...timing and precision. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating ryuk ransomware, which encrypts critical data and Inhibit System Recovery (T1490) with moderate to high confidence (80%), supported by evidence indicating halt noncritical surgeries and reroute patient care. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with lower confidence (40%), supported by evidence indicating russian-speaking cybercriminals...maximize disruption and financial gain. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
