Attack summary

Severity: medium — Confirmed exfiltration of healthcare-related personal data (patient records from an optometry clinic) is sensitive under GDPR/UK data protection law. However, the leak post provides no specific enumeration of proof files, no sample data excerpts, and no detail on scale of patient records affected. The post is part of a bulk multi-victim dump with inconsistent formatting and claims, reducing confidence in the specificity of the threat.

The dragonforce group claims to have exfiltrated 400 GB+ of data from Owen Leigh Optometry. The leak post is a multi-victim dump containing data from dozens of unrelated companies (law firms, HVAC contractors, financial lenders, resorts, etc.) alongside Owen Leigh Optometry; the group asserts the release includes patient data and internal documentation.

What the group claims

Full DATA 400 GB+ The brain uses the eyes to gather information about our surroundings. The brain cannot process all our view so it must first decide what to look for. The eyes-brain system then has to select that information, usually by shifting eye position and often by shifting focus. How the eyes-brain go through this process is the real test of visual efficiency. Here at Owen Leigh Optometry, we specialise in helping patients of all ages to develop flexibility in their vision to meet all their needs and interests. We start this by observing and measuring your eye-brain system with a wide range of visual challenges. Eye health and eyesight are important, but this must not be the end point of developing good vision. We want to take you much further than that, to explore ways that you can see more, feel more, move better, plan better and understand quicker. We use 'visual efficiency glasses', vision exercises (vision therapy) and 'training/learning lenses' to help you develop your own vision. We add visual hygiene, consider coloured lenses and refer to other disciplines if that will help you meet your goals. “What we see is dependant upon what we are looking for and what we managed to see last time.”

Disclosure context

About Dragonforce

Dragonforce is a relatively new ransomware group that emerged in December 2023, operating with apparent financial motivations based on their targeting patterns and victim selection. The group's origin and potential affiliations remain unclear due to limited public documentation from established threat intelligence sources, though their rapid accumulation of 439 documented victims suggests either sophisticated capabilities or possible connections to existing ransomware infrastructure. Based on their targeting patterns across diverse sectors including manufacturing, business services, technology, and construction, Dragonforce appears to employ opportunistic attack methodologies, though specific initial access vectors, encryption methods, and extortion tactics have not been publicly detailed by major security firms or law enforcement agencies. The group has demonstrated a preference for targeting organizations primarily in English-speaking countries and Western Europe, with the United States, United Kingdom, Germany, Australia, and Italy representing their most frequent victim locations, suggesting possible language capabilities or geographic operational preferences. As of current reporting, Dragonforce appears to remain active given their recent emergence and ongoing victim acquisition, though the lack of detailed public analysis from major threat intelligence organizations indicates either operational security measures that have limited researcher visibility or that the group has not yet conducted sufficiently high-profile attacks to warrant extensive public documentation by CISA, FBI, or established security research firms. The group has been linked to 669 public disclosures across our corpus. First observed on a leak site on December 13, 2023; most recent post September 16, 2026. The operation is currently active.

If your organisation is affected

A listing by Dragonforce means Owen Leigh Optometry appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Report the incident to your national CERT, NCSC (United Kingdom), as required for your jurisdiction.
Monitor for the data appearing on Dragonforce's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
