Four Eye Clinics Listed by abyss Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On 2 February 2025, Four Eye Clinics was listed by the abyss ransomware group as a victim of a ransomware attack in which internal files were claimed to have been exfiltrated. Public reporting so far provides no confirmed figure for the number of people affected, and the precise contents of the files remain undisclosed beyond the general description of internal material. The listing also referenced several related domains: centuryvisionglobal.com, independenceeye.com, kocheye.com and prairieeyecenter.com.

Because the organisation operates in eye care, any compromise of internal systems raises immediate questions about the security of operational and patient-related information. Details remain limited to the group’s claim and the sparse public summary; independent confirmation of the full scope has not been released.

Breaking down the breach

The incident is known only through the abyss group’s leak-site listing of Four Eye Clinics, reported on 2 February 2025. According to that listing, internal files were exfiltrated during a ransomware attack. No public information has been released about the date the intrusion began, how long the attackers remained inside the network, the initial access method, or whether encryption was also deployed. The number of people affected is listed as unknown. The only additional detail supplied is the set of associated domains noted above. All other operational specifics—volume of data taken, systems impacted, or any ransom demand—are undisclosed.

The group behind it: abyss

Abyss is a ransomware operation that has appeared in public reporting as a double-extortion actor: it typically encrypts systems while also stealing data and threatening to publish the material if payment is not made. Like other groups of this type, it maintains a leak site on which it posts victim names and, in some cases, sample files to pressure organisations. The group’s listings are claims made by the attackers themselves and are not independently verified at the moment of publication. In this instance, abyss has asserted that it obtained internal files from Four Eye Clinics; no further statements attributed specifically to this victim have been made public beyond that listing.

Four Eye Clinics and its sector

Four Eye Clinics appears to be an eye-care provider operating under or in association with the domains centuryvisionglobal.com, independenceeye.com, kocheye.com and prairieeyecenter.com. Organisations of this kind deliver ophthalmology and optometry services and therefore maintain clinical records, appointment systems, billing information and administrative files. Healthcare providers in general are attractive targets for ransomware groups because the data they hold is both sensitive and operationally critical; disruption can affect patient care schedules and regulatory compliance obligations. A breach claim against such a clinic therefore carries sector-wide relevance even when the exact technical details remain sparse.

What data was at risk

The only description given is that internal files were allegedly exfiltrated. No inventory of specific data categories—patient names, medical histories, financial records, employee details or otherwise—has been released. Eye clinics typically store protected health information, contact details, insurance data and operational documents. Because the precise contents of the claimed exfiltration have not been confirmed, it is not possible to state which of those categories, if any, were included. The absence of a detailed disclosure means the exact exposure remains unconfirmed.

Why it matters

For individuals who have been patients or staff of Four Eye Clinics or its associated practices, the primary concern is the potential misuse of any personal or medical information that may have been taken. Even without confirmed data types, internal files from a healthcare setting can enable identity fraud, targeted phishing or further social-engineering attempts. For the organisation itself, a ransomware claim can interrupt clinical operations, trigger regulatory notification duties and require costly recovery and monitoring efforts. Until more information is released, the practical impact on any given person cannot be quantified, but the combination of a healthcare provider and a ransomware group’s double-extortion model makes the incident consequential for those whose data may be involved.

Were you affected?

If you have been a patient, employee or contractor of Four Eye Clinics or any of the related practices, monitor account statements and medical correspondence for unusual activity and consider placing fraud alerts with credit bureaus. Change passwords on any accounts that may have reused credentials linked to the clinics, and enable multi-factor authentication where available. Because the number of people affected and the exact data taken remain unknown, a free exposure scan of your email address can help determine whether your information has already appeared in known breach datasets. Keep records of any official notifications you receive from the organisation itself, as those will contain the most authoritative guidance once further details are confirmed.
