Xsolis, a business associate of HIPAA-covered entities that provides AI-powered solutions for improving case and utilization management to achieve more efficient outcomes, has experienced a major data breach as a result of a phishing attack.

According to the data breach notification filed with the California Attorney General, unauthorized activity was identified within the Xsolis environment on January 22, 2026, as a result of a targeted phishing attack. The incident has been contained, unauthorized access has been terminated, no evidence has been found of unauthorized access since January 22, 2026, and Xsolis has found no evidence to suggest any of the exposed data has been misused.

An investigation was launched to determine the nature and scope of the unauthorized activity, which confirmed that patient data had been exposed and may have been copied. Xsolis engaged digital specialists to review the affected data, and that process has now been completed. Xsolis is notifying the affected individuals and has offered them complementary credit monitoring and identity theft protection services through Kroll for 12 months.

The Kroll website notice about the security incident states that an unauthorized third party had access to a limited portion of the Xsolis environment from January 20, 2026, to January 22, 2026. Data exposed in the incident included names, dates of birth, Social Security numbers, health insurance information, and medical treatment information.

The data breach has been reported to the HHS’ Office for Civil Rights as involving unauthorized access to the protected health information of 1,396,519 patients of its healthcare provider clients. A list of the affected clients has not been published; however, VHC Health, a healthcare provider serving patients in Northern Virginia and the Washington D.C. Metro area, has confirmed that it has been affected, as has Rochester Regional Health in New York.

Additional security measures have been implemented to prevent similar incidents in the future, system monitoring has been increased, all passwords for key users have been reset, new protective technologies have been deployed, security awareness training for employees has been accelerated, and credential management processes have been strengthened.

Providence St. Joseph Orange, California

Providence St. Joseph Orange, a catholic general hospital in Orange, California, has been affected by a data security incident at its vendor, Pinnacle Holdings, LTD, a health care consulting company. Pinnacle experienced a network disruption in November 2024, and the forensic investigation confirmed unauthorized access to its network between November 11, 2024, and November 25, 2024, during which time files containing protected health information may have been exfiltrated from Pinnacle’s network.

Data potentially compromised in the incident included patients’ first and last name, address, email address, date of birth, encounter ID number, health insurance claim number, health insurance policy number, medical record number, patient account number, patient ID number, phone number, email address, prescription information, social security number, Medicare/Medicaid number, provider name, date of service, health insurance information, treatment cost information, and/or medical/diagnostic information.

Corewell Health, Michigan

Corewell Health, a non-profit Michigan health system, has recently confirmed that the protected health information of more than 19,000 of its patients has been exposed in a data breach at one of its business associates, Colorado-based Pinnacle Holdings, LTD. Pinnacle Holdings, a provider of consulting services, experienced a network disruption on November 25, 2024, that affected some of its IT systems, including systems containing the protected health information of patients of its clients.

Pinnacle Holdings said immediate action was taken to secure its systems; however, the detailed data review has taken many months to complete due to the complexity of the impacted data. The company has now confirmed that patient names, phone numbers, birth dates, Social Security numbers, driver’s license numbers, health insurance information, prescription information, and dates of service were compromised. The affected Corewell Health patients have been offered complimentary credit monitoring and identity theft protection services, and Pinnacle Holdings has implemented additional safeguards to prevent similar incidents in the future.

The data breach at Pinnacle Holdings affected several of the company’s clients, including the Chicago-based Catholic health system, CommonSpirit Health, as previously reported by The HIPAA Journal.

Rocky Mountain Care, Utah

Rocky Mountain Care, a Woods Cross, Utah-based provider of skilled nursing care and home health services to seniors in Utah and Wyoming, has announced a January 2026 cybersecurity incident that involved unauthorized access to parts of its network that contained patient information. The forensic investigation determined that a hacker gained access to files on its network between January 30, 2026, and February 2, 2026. The review of the impacted data is ongoing, so the full impact of the incident has yet to be determined. Rocky Mountain Care said notification letters will be mailed to the affected individuals when the review is concluded

While further details about the attack have not been disclosed, a threat actor has claimed responsibility for the incident. The Qilin threat group added Rocky Mountain Care to its dark web data leak site on February 23, 2026, and issued a ransom demand along with a threat to publish the stolen data if the ransom was not paid. Samples of data allegedly stolen in the attack were also added to the listing. Qilin claimed to have exfiltrated 33 GB of data in the attack and later published the stolen data, indicating the ransom was not paid.

Orthopaedic Institute of Western Kentucky has notified patients that their PHI was compromised in two security incidents at their managed IT services provider. Supportive Home Health Care and Patriot Outpatient has identified unauthorized access to an employee’s email account.

Orthopaedic Institute of Western Kentucky

Orthopaedic Institute of Western Kentucky (now Mercy Health — Western Kentucky Orthopedics) in Paducah, Kentucky, has been affected by two security incidents at one of its business associates, the managed IT services provider Keystone Technologies.

Keystone Technologies notified the orthopedic institute about unauthorized access to Keystone systems on two occasions: the first between April 21, 2025, and April 26, 2025, and the second between July 19, 2025, and August 1, 2025. During both periods, unauthorized individuals exfiltrated files containing patient information. The affected files were reviewed, and the affected individuals were identified in December 2025 and January 2026. Data compromised in the incident included names, addresses, dates of birth, medical record numbers, Social Security numbers, treatment information, and health insurance information. Electronic medical records were not subject to unauthorized access, nor were any of Mercy Health’s systems.

The affected individuals have now been notified and offered a complimentary 12-month membership to a credit monitoring and identity theft protection service. 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.

Supportive Home Health Care and Patriot Outpatient

Superior Care Plus, LLC, doing business as Supportive Home Health Care and Patriot Outpatient, LLC (Patriot), a provider of home healthcare services in Northeast Ohio, has announced a data breach affecting 1,415 of its patients.

On November 17, 2025, suspicious activity was identified within an employee’s email account. An investigation was launched to determine the nature and scope of the activity, and Patriot confirmed that the email account was compromised as a result of the employee responding to a phishing email. No other email accounts or systems were compromised in the incident.

On January 9, 2026, the forensic investigation was completed, and Patriot confirmed that the compromised account contained first and last names, city/ZIP codes, email addresses, health insurance policy numbers, medical treatment information, admission/discharge dates, patient logs, referring facility, start care date, policy name, and referring primary care physician name. A limited number of individuals also had their Social Security numbers and/or Medicare numbers exposed.

Patriot has taken several steps to prevent further unauthorized access to email data. The affected email account was deleted, and the individual, and a new account was created, rather than reactivating the account after a password change. Further training has been provided to the workforce on email security and phishing email identification, and third-party cybersecurity experts have helped Patriot enhance its technical security measures and procedures.

Jackson Hospital and Clinic in Montgomery, Alabama, has notified 14,485 individuals about a July 2024 data breach at one of its former vendors, the debt collection agency Nationwide Recovery Services.

Nationwide Recovery Services first identified suspicious activity within its computer network in July 2024. The forensic investigation confirmed that an unauthorized third party accessed its network between July 5, 2024, and July 15, 2024. Nationwide Recovery Services notified the affected HIPAA-regulated entity clients between February 2025 and March 2025; however, Jackson Hospital and Clinic said it was not informed that it was one of the affected clients until January 27, 2026. Notification letters started to be mailed to the affected individuals on February 27, 2026, more than 19 months after the data breach occurred.

Jackson Hospital and Clinic said the incident involved data provided to Nationwide Recovery Services to allow the company to perform its contracted duties. None of Jackson Hospital and Clinic’s information technology systems were affected. Data potentially compromised in the incident includes names, phone numbers, addresses, dates of birth, Social Security numbers, account information, health insurance information, and/or dates of service. Jackson Hospital and Clinic said it no longer uses Nationwide Recovery Services for debt recovery.

As a precaution against data misuse, the affected individuals have been offered complementary credit monitoring and identity theft protection services. Due to the lengthy delay between the data breach and notification, the affected individuals should check their accounts and explanation of benefits statements for potential data misuse going back to July 2024, in addition to signing up for the complimentary credit monitoring services.

The total number of individuals affected by the Nationwide Recovery Services is unknown.  Nationwide Recovery Services reported the breach to the HHS’ Office for Civil Rights (OCR) on September 9, 2024, using a placeholder figure of at least 501 affected individuals. That total has not been updated since the initial breach report. Many clients chose to issue their own notifications about the data breach. Based on breach notifications to state attorneys general and OCR, the data breach affected more than 560,000 individuals.

The U.S. medical device manufacturer UFP Technologies has submitted a FORM 8-K filing to the U.S Securities and Exchange Commission (SEC) to notify the SEC and investors about a cyberattack and data breach that could potentially impact its financial condition or operations.

UFP Technologies is a publicly traded contract manufacturer based in Newburyport, Massachusetts, that makes single-use medical devices and highly engineered components for the aerospace, automotive, healthcare, and defense industries. The company produces a wide range of medical devices and medical components for products used in wound care, implants, and orthopedic and surgical products. UFP Technologies has an annual revenue of $600 million and employs 4,300 people.

According to the filing, UFP Technologies detected an IT systems intrusion on February 14, 2026. Immediate action was taken to assess, contain, and remediate the threat, and third-party cybersecurity experts were engaged to assist with the investigation. UFP Technologies said it believes the cyber threat actor responsible for the attack has been eradicated from its IT environment and confirmed that it has restored access to systems and information impacted by the incident in all material respects. While the attack did not impact all of its IT systems, many were affected, including the systems used for billing and label-making. UFP Technologies implemented its incident response and contingency plans, and since the incident was detected, it was able to continue operations in all material respects.

Some company and company-related data was either stolen or destroyed in the attack, which suggests this was a ransomware attack or that wiper malware was used. No threat group appears to have claimed responsibility for the attack. UFP Technologies explained in the filing that data has been recovered from backups. The company has confirmed that some data was exfiltrated from its system, although it is too early to determine the extent of the data theft, such as whether any personal or protected health information was stolen. The investigation to determine the nature and scope of the incident is ongoing, and the company is exploring the legal and regulatory notifications and filings that may be required.

As of the date of the filing (February 19, 2026), UFP Technologies said the incident has not had any material impact on its financial systems, operations, or financial condition. While costs have naturally been incurred, the company expects a significant proportion of the costs of containment, investigation, and mitigation will be covered by its cyber insurance policy.

Vikor Scientific (now rebranded as Vanta Diagnostics), a molecular diagnostics company based in Charleston, South Carolina, has been affected by a security incident at one of its vendors – the revenue cycle management company, Catalyst RCM. The breach also affected the Vikor Scientific-owned molecular testing laboratory KorGene,  and KorPath, a Tampa, Florida-based anatomical pathology lab, which partners with Vanta Diagnostics. Vikor Scientific has reported the data breach to the HHS’ Office for Civil Rights as involving the electronic protected health information (ePHI) of 139,964 individuals.

Catalyst RCM has published a substitute breach notice on its website and is issuing notification letters to the affected individuals on behalf of its affected HIPAA-covered entity clients. While it is ultimately the responsibility of each affected HIPAA-covered entity to issue notification letters when there has been a data breach at a vendor, the notification responsibilities are often delegated to the vendor.

In the breach notice, Catalyst RCM explains that suspicious activity was identified within its secure file management system on or around November 13, 2025. An investigation was launched, which identified an unauthorized login to a system used to access one of its servers. The server was accessed without authorization between November 8, 2025, and November 9, 2025. The affected system was reviewed to determine whether any protected health information had been exposed or stolen, and the review concluded on December 12, 2025. Catalyst RCM confirmed that the threat actor exfiltrated data in the attack.

Data potentially compromised in the incident varies from individual to individual and may include names plus one or more of the following: date of birth, diagnosis information, medical treatment information, history, health insurance information, and/or payment card information with access code.

Catalyst RCM has updated its security policies, procedures, and protocols to reduce the likelihood of similar incidents in the future, and has advised the affected individuals to remain vigilant against identity theft and fraud by monitoring their free credit reports. While no misuse of the affected data has been identified, the affected individuals have been offered complimentary credit monitoring and identity theft protection services.

While the incident was not described as a ransomware attack, the Everest ransomware group claimed responsibility for the attack and added Vikor Scientific to its dark web data leak site, along with samples of data allegedly stolen in the attack. Everest threatened to leak the stolen data if contact was not made. Everest claims to have leaked all data exfiltrated in the attack, indicating the ransom was not paid.
