Full Incident Analysis Transcript

In this Rankiteo incident briefing, we review the Shared Health breach identified under incident ID SHACAN1787063945.

The analysis begins with a detailed overview of Shared Health's information like the linkedin page: https://www.linkedin.com/company/sharedhealth, the number of followers: 1248, the industry type: Hospitals and Health Care and the number of employees: 206 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 763 and after the incident was 660 with a difference of -103 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 Shared Health and their customers.

On 10 August 2026, Shared Health disclosed ransomware issues under the banner "Winnipeg Health Authority Ransomware Attack".

On August 10, 2026, Shared Health confirmed a ransomware attack disrupted maintenance systems at Winnipeg’s Health Sciences Centre (HSC) and Cancer Care Manitoba, targeting central monitoring for heating, ventilation, and cooling (HVAC) infrastructure.

The disruption is felt across the environment, affecting HVAC monitoring systems, security office (ID access card issuance), and exposing No personal health or financial data compromised (initial review).

In response, moved swiftly to contain the threat with measures like Additional security measures implemented, while recovery efforts such as Systems remain operational under local oversight continue.

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 (50%), supported by evidence indicating targeting central monitoring for heating, ventilation, and cooling (HVAC) and Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating halted ID access card issuance and updates (implied compromised credentials). Under the Execution tactic, the analysis identified User Execution: Malicious File (T1204.002) with moderate to high confidence (70%), supported by evidence indicating ransomware attack disrupted maintenance systems. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating ransomware attack disrupted maintenance systems (HVAC monitoring) and Defacement: Internal Defacement (T1491.001) with moderate confidence (60%), supported by evidence indicating forced the closure of the health centre’s security office. Under the Defense Evasion tactic, the analysis identified Masquerading (T1036) with moderate confidence (50%), supported by evidence indicating systems remain operational under local oversight (bypass monitoring). Under the Lateral Movement tactic, the analysis identified Exploitation of Remote Services (T1210) with moderate confidence (60%), supported by evidence indicating targeting central monitoring for HVAC (implied network traversal). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
