Full Incident Analysis Transcript

In this Rankiteo incident briefing, we review the UHS breach identified under incident ID UHSCHAUNI1774542502.

The analysis begins with a detailed overview of UHS's information like the linkedin page: https://www.linkedin.com/company/uhs, the number of followers: 90967, the industry type: Hospitals and Health Care and the number of employees: 11391 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 700 and after the incident was 576 with a difference of -124 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 UHS and their customers.

On 10 September 2020, Düsseldorf University Clinic disclosed Ransomware issues under the banner "First Fatality Linked to Ransomware Attack on Düsseldorf University Clinic".

A ransomware attack on Düsseldorf University Clinic in Germany disrupted critical IT systems, forcing the hospital to divert emergency patients.

The disruption is felt across the environment, affecting Critical IT systems.

Formal response steps have not been shared publicly yet.

The case underscores how teams are taking away lessons such as The incident highlights the escalating risks of cyberattacks on healthcare, emphasizing the need for increased cybersecurity investment to prevent patient harm and operational disruptions, and recommending next steps like Healthcare organizations should allocate a higher percentage of IT budgets to cybersecurity (targeting 15% or more) and recognize ransomware as both a patient safety and reputational risk.

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 (50%), supported by evidence indicating disrupted critical IT systems, forcing the hospital to divert emergency patients and Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating healthcare organizations historically underinvested in cybersecurity. Under the Execution tactic, the analysis identified Exploitation for Client Execution (T1203) with moderate to high confidence (70%), supported by evidence indicating ransomware attack disrupted critical IT systems. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating data encryption such as Yes in ransomware section and Inhibit System Recovery (T1490) with moderate to high confidence (80%), supported by evidence indicating disrupted critical IT systems, forcing diversion of emergency patients. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with lower confidence (40%), supported by evidence indicating cybercriminals typically target hospitals for financial gain. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with moderate confidence (60%), supported by evidence indicating ransomware attack disrupted systems despite underinvestment in cybersecurity. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
