Viapath Breach Incident Score: Analysis & Impact (VIA3232032111125)

In this Rankiteo incident briefing, we review the Viapath breach identified under incident ID VIA3232032111125.

The analysis begins with a detailed overview of Viapath's information like the linkedin page: https://www.linkedin.com/company/viapath-llp, the number of followers: 7271, the industry type: Hospitals and Health Care and the number of employees: 272 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 762 and after the incident was 660 with a difference of -102 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 Viapath and their customers.

On 20 June 2024, Synnovis disclosed ransomware and data breach issues under the banner "Synnovis Ransomware Attack and Data Breach (2024)".

A ransomware attack on Synnovis, a pathology supplier for NHS providers, led to widespread disruption of NHS services in London, including delayed appointments and blood testing.

The disruption is felt across the environment, affecting Synnovis corporate systems and administrative working drive, and exposing patient names, NHS numbers and test results.

In response, teams activated the incident response plan, and began remediation that includes investigation into stolen data and notification of affected organizations, while recovery efforts such as dedicated support for affected NHS providers and website with updates for stakeholders continue, and stakeholders are being briefed through direct notifications to NHS organizations, public statements and patient notifications via letters/website.

The case underscores how completed (as of November 2025), teams are taking away lessons such as challenges in investigating unstructured, fragmented stolen data, need for improved cybersecurity in NHS supply chain and importance of coordinated response for large-scale breaches, and recommending next steps like public inquiry into NHS cybersecurity, enhanced protection for third-party suppliers and proactive patient notification protocols, with advisories going out to stakeholders covering dedicated Synnovis website for updates and direct support to affected NHS organizations.

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 Exploit Public-Facing Application (T1190) with moderate to high confidence (70%), supported by evidence indicating ransomware attack on 4 June 2024 (no vector specified, but common for healthcare) and Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating synnovis corporate systems compromised (possible abused credentials). Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol: Exfiltration Over Unencrypted/Obfuscated Non-C2 Protocol (T1048.003) with high confidence (90%), supported by evidence indicating stolen data was unstructured, fragmented, and incomplete (published online) and Automated Exfiltration (T1020) with moderate to high confidence (80%), supported by evidence indicating patient and staff data (names, NHS numbers, test results) exfiltrated in bulk. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (95%), supported by evidence indicating ransomware attack with data encryption confirmed and Data Destruction (T1485) with moderate to high confidence (70%), supported by evidence indicating widespread disruption to NHS services (operational impact suggests systemic data/systems corruption). Under the Credential Access tactic, the analysis identified Credentials from Password Stores (T1555) with moderate confidence (60%), supported by evidence indicating synnovis corporate systems breach (common target for credential harvesting). Under the Defense Evasion tactic, the analysis identified Indicator Removal: File Deletion (T1070.004) with moderate to high confidence (70%), supported by evidence indicating investigation into stolen data complicated by unstructured, fragmented files (suggests cleanup) and Impair Defenses: Disable or Modify Tools (T1562.001) with moderate confidence (60%), supported by evidence indicating widespread disruption implies possible disabling of security/operational tools. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating patient names, NHS numbers, test results, administrative records stolen from local drives. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
