In this Rankiteo incident briefing, we review the Doctor Alliance breach identified under incident ID DOC0894308111825.

The analysis begins with a detailed overview of Doctor Alliance's information like the linkedin page: https://www.linkedin.com/company/doctor-alliance, the number of followers: 2591, the industry type: Hospitals and Health Care and the number of employees: 114 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 628 and after the incident was 357 with a difference of -271 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 Doctor Alliance and their customers.

On 07 November 2025, Doctor Alliance disclosed Data Breach and Ransomware Attack issues under the banner "Doctor Alliance Data Breach and Ransomware Attack".

On Nov.

The disruption is felt across the environment, affecting EHR-integrated platform and Clinical/Administrative data processing systems, and exposing PII (names, addresses, phone numbers, SSNs, dates of birth) and PHI (medical/treatment info, health insurance info), with nearly 1.2 million+ files (353 GB) records at risk.

In response, and stakeholders are being briefed through No public statement issued as of reporting, Advisories for affected individuals to: and - Monitor credit reports/medical bills.

The case underscores how Ongoing (no official updates from Doctor Alliance), and recommending next steps like Implement multi-layered security for EHR-integrated systems, Enhance monitoring for exfiltration of large data volumes and Develop pre-approved public communication templates for ransomware events, with advisories going out to stakeholders covering Monitor credit reports and medical bills, Contact healthcare providers regarding records and Avoid sharing sensitive info in unsolicited communications.

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.

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 Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating infiltrated its files (no specific vector, but EHR/clinical systems likely targeted) and Exploit Public-Facing Application (T1190) with moderate confidence (60%), supported by evidence indicating eHR-integrated platform and clinical/administrative data processing systems compromised. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol: Exfiltration to Cloud Storage (T1048.003) with moderate to high confidence (85%), supported by evidence indicating exfiltrating over **1.2 million files (353 GB)** (large-scale data transfer implied) and Automated Exfiltration (T1020) with moderate to high confidence (80%), supported by evidence indicating 1.2M+ files exfiltrated (suggests scripted/automated collection). Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with moderate to high confidence (75%), supported by evidence indicating ransomware attack (double extortion such as exfiltration + encryption implied) and Data Destruction (T1485) with moderate confidence (50%), supported by evidence indicating threat to release the stolen data (potential destruction if unpaid). Under the Credential Access tactic, the analysis identified Credentials from Password Stores (T1555) with moderate confidence (60%), supported by evidence indicating eHR systems often store credentials; infiltrated suggests lateral movement. Under the Defense Evasion tactic, the analysis identified Indicator Removal: File Deletion (T1070.004) with moderate confidence (65%), supported by evidence indicating no logs/details on containment; threat actor operated undetected until ransom demand and Impair Defenses: Disable or Modify Tools (T1562.001) with moderate confidence (60%), supported by evidence indicating lack of detection until ransom note suggests possible defense impairment. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating 1.2 million files (353 GB) including PII/PHI collected from EHR systems and Data from Network Shared Drive (T1039) with moderate to high confidence (80%), supported by evidence indicating clinical/administrative data processing systems (shared drives likely). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
