Analysis Summary
# Incident Report: UTHC Client and Staff Data Compromise
## Executive Summary
The Ungava Tulattavik Health Centre (UTHC) experienced a cyberattack in November that led to the compromise of client and staff information. Initial analysis incorrectly suggested no sensitive data was breached; however, subsequent investigation confirmed that records potentially containing clinical and administrative information concerning certain users and employees may have been stolen. The UTHC has activated a crisis unit, engaged provincial cybersecurity support, and launched an investigation with police assistance.

## Timeline of Events
### Initial Access
- **Date/Time:** November (Specific date unknown).
- **Vector:** Undisclosed cyberattack.
- **Details:** Attackers gained access resulting in the compromise of client and staff information.
### Lateral Movement
- **Details:** Not specified in the source material.
### Data Exfiltration/Impact
- **Details:** Files "potentially containing clinical and administrative information concerning certain users and employees" may have been stolen. Initial assessment that no sensitive data was compromised was later revised.
### Detection & Response
- **Detection:** Initial detection occurred sometime after the attack in November, followed by an evolving status determined via further analysis.
- **Response Actions:** UTHC established a crisis unit, began working with Santé Québec's Cyber Defence Operations Centre, set up a dedicated information service for affected parties, and alerted clients/staff to remain vigilant. Quebec provincial police are investigating.
## Attack Methodology

## Lessons Learned
- Initial assessment of security incidents can be inaccurate, leading to underestimation of the true scope of a data breach until deeper forensic analysis is complete.
- Rapid escalation and engagement of specialized cybersecurity support (e.g., Santé Québec's Cyber Defence Operations Centre) is critical following a breach confirmation.
## Recommendations
- Immediately perform thorough forensic analysis to accurately determine the full scope of compromised data fields and records.
- Implement enhanced monitoring and network segmentation to prevent initial access vectors from leading to subsequent lateral movement and exfiltration.
- Conduct immediate mandatory security awareness training focusing on phishing and vigilance against social engineering, given the warning issued to staff and clients regarding suspicious contact.
