Data breaches have been confirmed by the revenue cycle management company MedRevenu Inland Physicians Hospitalist Services, and the Missouri-based eye care provider, EyeCare Partners.

MedRevenu Inland Physicians Hospitalist Services

MedRevenu Inland Physicians Hospitalist Services, a Montclair, CA-based vendor that provides revenue cycle management services to healthcare providers, has recently notified the California Attorney General about a cybersecurity incident. The incident occurred on or around December 12, 2024, and caused disruption to its network. The forensic investigation determined that files containing personal and protected health information may have been accessed or acquired in the incident, including names, dates of birth, Social Security numbers, driver’s license numbers/government identification numbers, health insurance information, medical information, financial account numbers, payment card numbers, and access information.

MedRevenu said it is reviewing and enhancing its cybersecurity measures and has offered the affected individuals complimentary single-bureau credit monitoring, credit report, and credit score services for 12 months. The BianLian threat group claimed responsibility for the attack and added MedRevenu to its dark web data leak site on December 14, 2024. Since data has been leaked, the affected individuals should ensure that they sign up for the credit monitoring services being offered and carefully check their account statements for data misuse, going back to December 2024. The incident is not yet shown on the HHS’ Office for Civil Rights breach portal, so it is currently unclear how many individuals have been affected.

EyeCare Partners

EyeCare Partners, LLC, a St. Louis, MO-based nationwide provider of eye care services, has recently announced an email security incident that was first identified on January 28, 2025. Suspicious email activity was identified, and an investigation was launched, which confirmed that an unauthorized third-party had accessed multiple managed email accounts between December 3, 2024, and January 28, 2025.

It took until November 11, 2025, to review the compromised accounts, and notifications were issued to appropriate state attorneys general in February 2026. Data compromised in the incident includes names, contact information, dates of birth, Social Security numbers, driver’s license numbers/state identification numbers, health plan information, and limited clinical information.

EyeCare Partners said it has no reason to believe that any of the exposed information has been misused for identity theft or fraud; however, out of an abundance of caution, the affected individuals have been offered complimentary single-bureau credit monitoring, credit report, and credit score services for 24 months. EyeCare Partners said it has reviewed and enhanced its technical security measures and has provided further reminders to employees about how to recognize and avoid phishing attempts. The incident has been reported to the HHS’ Office for Civil Rights as affecting 17,110 individuals, including patients of The Ophthalmology Group, Ophthalmology Consultants, and Ophthalmology Associates.

The Counseling Center of Wayne and Holmes Counties has experienced a cyberattack affecting 83,350 individuals. Data breaches have also been announced by Neurological Associates of Washington and Pecan Tree Dental.

Counseling Center of Wayne and Holmes Counties

The Counseling Center of Wayne and Holmes Counties (CCWHC) in Wooster, Ohio, has experienced a data security incident affecting 83,354 individuals. On March 3, 2025, CCWHC’s third-party service provider notified CCWHC about a cybersecurity incident, which caused disruption to its IT systems. An investigation was launched, and steps were taken to contain and remediate the incident. All impacted systems and accounts were removed, credentials were reset, and leading data privacy and security experts were engaged to assist with the investigation.

The forensic investigation determined that an unauthorized third party gained access to a single CCWHC server on March 2, 2025, and exfiltrated files on March 3, 2025. Based on the initial findings of the investigation, the general types of information compromised in the incident include names, dates of birth, Social Security numbers, driver’s license numbers/state identification numbers, health insurance information, medical condition information, treatment provider names, medical record numbers, treatment cost information, diagnoses, and treatment information.

CCWHC has worked with cybersecurity experts and privacy professionals to review and further strengthen system security. The file review was completed on December 9, 2025, and notification letters have now been mailed to the affected individuals.

Neurological Associates of Washington

Neurological Associates of Washington (NAW) has recently confirmed that the personal and protected health information of 13,500 individuals was stolen in a December 2025 cyberattack. It is now rare for a healthcare provider to disclose details about a hacking incident in its data breach notice; however, NAW has bucked that trend and disclosed that the Dragonforce ransomware group was behind the attack. NAW also confirmed that sensitive patient data was stolen and published on the dark web by Dragonforce.

NAW immediately alerted the Federal Bureau of Investigation (FBI), which investigated the incident and confirmed that the stolen data was published on the dark web on December 28, 2025. The FBI is conducting further investigations into the attack, but has confirmed that the data compromised in the incident related to patients from 2019 to 2025. Data compromised in the incident included names, addresses, dates of birth, Social Security numbers, diagnoses, disability codes, medical information, and other types of data. New patients from January 2025 onwards had their data added to a new cloud-based records system, which was not accessed in the attack.

NAW said it has implemented a deep reset and restructuring of its IT system in response to the incident and confirmed that the affected database is now stored in an offline environment. At the time of issuing notifications, NAW said it was unaware of any actual or attempted misuse of the stolen data. As a precaution against identity theft and fraud, the affected individuals have been offered 12 months of complimentary credit monitoring services.

Pecan Tree Dental

Pecan Tree Dental, PLLC, in Grand Prairie, Texas, has confirmed that it experienced a cybersecurity incident involving unauthorized access to its computer systems. The website notice is light on detail, only stating that steps have been taken to secure its systems, and cybersecurity and legal professionals have been engaged to assist with the investigation. At the time of uploading the notice to its website, it was unaware of any unauthorized access to patient information or data misuse. The OCR breach portal indicates that up to 13,300 individuals had their protected health information exposed in the incident.

The Texas attorney general was informed that data compromised in the incident includes names, addresses, dates of birth, medical information, and health information. This appears to have been a ransomware attack by the Sinobi threat group, which added Pecan Tree Dental to its dark web data leak site on January 11, 2026. Sinobi claims to have exfiltrated 250 Gb of data in the attack and has leaked the stolen data.

Precipio, Inc.

Precipio, Inc., a Connecticut-based laboratory specializing in advanced hematopathology diagnostics, has discovered unauthorized access to an employee’s cloud-based storage account. Suspicious activity was identified within the email account on or around November 25, 2025, and the investigation confirmed that an unauthorized third party accessed the employee’s account from November 23, 2025, to November 25, 2025, during which time, files were copied from the account.

The affected files are currently being reviewed to determine the information involved, and that process is currently ongoing. Precipio has yet to disclose a final list of the affected data, but said that, based on its investigation so far, information compromised in the incident includes names, addresses, dates of birth, medical record numbers, clinical/treatment information, medical procedure information, medical provider names, prescription information, and health insurance information.

Since the file review has not yet concluded, the HHS’ Office for Civil Rights has been provided with an interim total of at least 501 affected individuals. The total will be updated when the file review is completed.

Pit River Health Service

Pit River Health Service, the operator of two healthcare clinics in Burney and Alturas in California, has recently announced a data breach affecting up to 1,800 individuals. An unauthorized third party hacked its systems and potentially copied data. Pit River Health Service has confirmed that no data was altered or deleted in the attack, and the Indian Health Service medical record system was not accessed.

In a website update, Pit River Health Service confirmed that some of the affected systems have been restored, although a more extensive security review has been conducted for other affected systems. As a result of the attack, some patient services have been delayed, but appointments and services are continuing. In response to the incident, security monitoring has been stepped up across all of its IT systems.

Tulane University Medical Group

A data breach has been reported to the HHS’ Office for Civil Rights by Administrators of the Tulane Educational Fund d/b/a Tulane University Medical Group. The Louisiana-based medical group experienced a ransomware attack that involved unauthorized access to the protected health information of 6,530 patients.

Tulane University Medical Group does not currently have a substitute data breach notice on its website, so it is unclear exactly what types of information were compromised in the incident. The Cl0p ransomware group claimed responsibility for the attack and added the medical group to its data leak site. Cl0p exploits vulnerabilities in mass attacks, typically vulnerabilities in file-sharing software. Sensitive data is stolen, and ransom demands are issued. Cl0p claims to have exploited a vulnerability on or around November 18, 2025.

Iroquois Memorial Hospital, Illinois

Iroquois Memorial Hospital in Watseka, Illinois, has recently reported a hacking incident to the HHS’ Office for Civil Rights involving unauthorized access or theft of patients’ protected health information. A substitute breach notice has yet to be posted to the hospital’s website, so it is unclear exactly what types of data were compromised in the incident. The Pear threat group claimed responsibility for the attack.

Pear engages in data theft and extortion but does not encrypt files. The group maintains a data leak site and added Iroquois Memorial Hospital to the site on December 11, 2025. The listing is still active, which suggests the ransom was not paid. The HHS’ Office for Civil Rights breach portal indicates 621 individuals were affected by the incident
