41,000 Connecticut Medicaid Recipients Affected by DHS Data Incident

Data breaches have been announced by the Connecticut Department of Social Services, Public Partnerships LLC, Hattiesburg Eye Clinic, and the Eye Care Center of Snohomish.

Connecticut Department of Social Services

The  Connecticut Department of Social Services (DSS) has reported a data breach involving the protected health information of 41,000 individuals. The incident involved claims and payment information related to the Connecticut Medicaid (HUSKY) program, which was exposed after an unauthorized user gained access to a Connecticut Medicaid provider reimbursement account. DSS was informed about the data breach by its fiscal agent and account administrator, Gainwell Technologies, on June 25, 2026. The investigation determined that the unauthorized access was most likely financially motivated, rather than to obtain patient data; however, data theft could not be ruled out.

The provider portal has been secured, and the affected individuals have been offered complimentary credit monitoring and identity theft protection services. Electronic medical records, financial information, and Social Security numbers were not involved. The breach involved a combination of names, identification numbers associated with Medicare claims or provider payment accounts, dates of service, payment information, information about the services received, amounts paid, and information related to non-Medicaid health insurance.

This is the second such incident to be announced this year. An earlier breach in March 2026 affected approximately 22,500 individuals and involved unauthorized access to the HUSKY system using the compromised credentials of a Hartford Healthcare employee.

Public Partnerships LLC, New York

A data breach we had previously missed was reported by Public Partnerships LLC in early August that involved the attempted sale of the protected health information of 12,018 individuals. Public Partnerships is the single fiscal intermediary (FI) for the New York Consumer Directed Personal Assistance Program (CDPAP). CDPAP is a state Medicaid program that allows individuals who require home care to choose, hire, train, and manage their own caregivers.

In June 2026, Public Partnerships learned that a former facilitator had attempted to sell consumer data to another New York CDPAP facilitator. The former facilitator had been terminated by Public Partnerships in March 2026 for (unspecified) non-compliance with the program integrity requirements. The facilitator who was approached and offered the data refused and reported the incident to Public Partnerships.

Before Public Partnerships became the single FI for CDPAP, the state used hundreds of localized independent organizations. These legacy FIs became network facilitators or subcontractors under Public Partnerships under the single statewide contract with Public Partnerships. When it learned of the alleged sale, the former FI was contacted, informed about the allegation, and was told that offering to sell CDPAP data is unlawful and a breach of its ongoing contractual obligations. The former FI was instructed to delete all CDPAP data in its possession. Public Partnerships also notified all remaining facilitators of their contractual obligations and that the sale and purchase of CDPAP data is unlawful.

The case has been reported to the HHS Office for Civil Rights and the HHS Office of Inspector General, and all potentially impacted individuals have been notified by mail. The impacted data included names, addresses, dates of birth, Medicaid ID numbers, PPL ID numbers, and information relating to enrollment in New York Medicaid. While the sale appears not to have gone ahead, and there have been no other known cases, the affected individuals have been offered complimentary identity protection and credit monitoring services.

Hattiesburg Eye Clinic, P.A., Mississippi

Hattiesburg Eye Clinic, P.A. in Mississippi has reported a data security incident that potentially involved unauthorized access to the protected health information of 6,137 individuals. A network disruption was experienced on August 18, 2026, and third-party cybersecurity experts were engaged to investigate and determine the nature and scope of the activity. The review of the incident concluded on September 16, 2026, and confirmed that patient data had been exposed and may have been acquired. The affected data varied from individual to individual and may have included first and last names, phone numbers, Social Security numbers, and medical diagnoses/conditions.

Additional technical safeguards have been implemented to prevent similar incidents in the future, and notification letters have been mailed to all potentially affected individuals. A ransomware and data theft/extortion group called The Gentlemen claimed responsibility for the incident and maintains that patient data was stolen.

Anup K. Deol, OD PS (Eye Care Center of Snohomish), Washington

Anup K. Deol, OD PS, doing business as Eye Care Center of Snohomish in Washington, has identified unauthorized access to parts of its network containing the protected health information of 3,059 patients. The unauthorized access was identified on August 12, 2026, and third-party cybersecurity experts were engaged to investigate the activity. The investigation confirmed that an unauthorized third party gained access to limited files on its network on or around July 28, 2026.

The review of the affected files was completed on September 28, 2026. The data involved varied from individual to individual and may have included names, addresses, birth dates, and medical information, which may have included lab results, diagnoses, medications, and treatment information. The incident was reported to law enforcement, and additional safeguards have been implemented to prevent similar incidents in the future.

August 2026 Healthcare Data Breach Report

An analysis of data breaches affecting 500 or more individuals reported to the U.S. Department of Health and Human Services (HHS) Office for Civil Rights (OCR) in August 2026 shows a considerable improvement from the previous month. Data breaches are down 34% month-over-month, with August’s total of 52 data breaches, the second-lowest monthly total in the past 12 months, well below the 12-month average of 66 data breaches per month.

Healthcare data breaches in the past 12 months - August 2026

While August was a relatively good month for healthcare data breaches, the year-to-date figures show that 2026 is turning out to be another bad year for healthcare data breaches. Last year was the worst-ever year for healthcare data breaches, with 807 incidents reported. So far this year, 593 large healthcare data breaches have been reported to OCR. At this time last year, the total stood at 556 data breaches. That’s a 6.7% year-over-year increase.

YEar to date healthcare data breaches - August 2026

Across the 52 data breaches, the protected health information of at least 8,377,327 individuals was exposed or impermissibly accessed or disclosed. While that represents a 75% month-over-month decrease in affected individuals, July was one of the worst months in recent history for breached healthcare records, with more than 33 million affected individuals.

Individuals affected by healthcare data breaches in the past 12 months - august 2026

This year has already seen the protected health information of 78.6 million individuals exposed or impermissibly accessed or disclosed. That represents a 14.8% year-over-year increase in affected individuals.

The Biggest Healthcare Data Breaches in August 2026

Two data breaches stand out in August in terms of scale. The largest data breach of the month, and the fourth largest data breach to be reported by a HIPAA-regulated entity so far this year, involved unauthorized access to the protected health information of more than 4.1 million individuals. The incident occurred at AdaptHealth, a healthcare company that provides home medical equipment, diabetes supplies, and sleep therapy products. AdaptHealth was contacted by a member of the ShinyHunters data theft and extortion group in June and was informed that its network had been accessed and sensitive data exfiltrated. Data theft was later confirmed.

The second largest data breach was reported by the clinical genomics company Baylor Genetics. An unknown hacker accessed parts of its network that contained the protected health information of more than 2.8 million patients. These were two of 17 data breaches affecting more than 10,000 individuals, and all but two of those incidents were hacking incidents. No information has been released on one of the non-hacking incidents. The other involved data theft by a former facilitator who stole data and attempted to sell it to another individual.

When the breach notification deadline is reached, and the number of affected individuals has yet to be determined, data breaches need to be reported to OCR using an estimate of the number of affected individuals. Most regulated entities choose to report these breaches using a figure of 500 or 501 affected individuals, then update the breach report when the data review is concluded. In August, 7 such incidents were reported using these placeholder figures. These incidents are likely to have affected substantially more individuals than the initial breach report suggests.

Causes of August 2026 Healthcare Data Breaches

The majority of the month’s data breaches were hacking and other IT incidents, which accounted for 78.8% of the month’s data breaches and 98% of the affected individuals (8,215,959). On average, these incidents involved the exposure or theft of the protected health information of 205,399 individuals, with a median breach size of 5,258 individuals.

Causes of august 2026 healthcare data breaches

The year-to-date figures show a slight year-over-year increase in hacking/IT incidents. Between January 1 and August 30, 2026, 457 hacking/IT incidents have been reported, compared to 453 incidents for the corresponding period in 2025. While hacking incidents are only up by 0.9% year-over-year, 74,315,731 individuals have been affected, which is an 18.7% increase compared to this time last year.

There were 12 unauthorized access/disclosure incidents in August, involving the protected health information of 161,368 individuals. The average breach size was 13,447 individuals, and the median breach size was 4,024 individuals. The year-to-date figures show a 21.2% decrease in unauthorized access/disclosure incidents compared to this time last year, with incidents dropping from 94 for the period from January 1 to August 31 to 74 this year. So far this year, 1,651,788 individuals have been affected by these incidents, 71.7% fewer individuals than this time last year.

No loss, theft, or improper disposal incidents were reported in August.  The year-to-date figures show a 75% year-over-year decrease in loss/theft incidents, with only two such incidents reported so far this year compared to 8 last year. There have been two unauthorized disposal incidents reported this year, compared to one such incident for the corresponding period in 2025.

Location of Breached Protected Health Information

In August, the most common location of breached protected health information was network servers, with email accounts the next most common location of breached data.

Data Breaches at HIPAA Regulated Entities

The HIPAA Breach Notification Rule requires HIPAA-covered entities to report data breaches to OCR and notify the affected individuals. Notifications must also be issued when there is a data breach at a business associate of a HIPAA-covered entity; however, it is ultimately the responsibility of each affected HIPAA-covered entity to ensure that notifications are issued. A covered entity may delegate the reporting requirements to the business associate that experienced the data breach or may choose to issue notifications themselves. The raw breach data on the OCR breach portal shows data breaches based on the reporting entity, not where the data breach occurred.

In August, healthcare providers reported 41 data breaches, business associates reported 8 breaches, and 3 breaches were reported by health plans. The pie charts below show where the breach actually occurred rather than the reporting entity to better reflect data breaches at business associates.

HIPAA Enforcement Activity in August 2026

OCR announced one enforcement activity in August to resolve noncompliance with the HIPAA Rules. Azul Vision, Inc., a California optometry and ophthalmology service provider, agreed to settle an alleged violation of the HIPAA Privacy Rule’s right of access for $50,000. A patient was not provided with timely access to her medical records. She filed a complaint with OCR after 3 months and finally received the records two years after the initial request was made. State Attorneys General may also impose penalties for HIPAA violations, although no HIPAA violation cases were announced in August.

Lehigh Valley Health Network Pays $800K Penalty to Resolve HIPAA Violations

Lehigh Valley Health Network has agreed to settle alleged violations of the HIPAA Rules with the HHS’ Office for Civil Rights (OCR) and will pay an $800,000 financial penalty and adopt a corrective action plan to address identified areas of noncompliance. This is OCR’s 22nd investigation of a ransomware attack to result in a financial penalty for noncompliance with the HIPAA Rules.

OCR launched an investigation after receiving a breach report on May 15, 2026, from Lehigh Valley Health Network about a cybersecurity incident that exposed the protected health information (PHI) of 248,359 individuals. Lehigh Valley Health Network identified suspicious activity within its network in early February 2023 and later confirmed that ransomware was involved. The ALPHV/BlackCat ransomware group breached parts of its network, specifically IT systems related to Delta Medix, a company acquired by Lehigh Valley Health Network in 2021. The ransomware group exfiltrated files containing patient information and issued a ransom demand. The ransom was not paid, and the stolen data was leaked on the ransomware group’s dark web data leak site.

Data stolen and leaked in the incident included names, addresses, dates of birth, Social Security numbers, driver’s license numbers, financial information, diagnoses and conditions, lab results, medications, and treatment information. In addition, photographs of cancer patients receiving radiation oncology treatment were stolen in the incident and leaked online, including photographs of patients who were naked from the waist up. Lehigh Valley Health Network was sued over the data breach and settled the class action litigation for $65 million.

OCR’s investigation identified multiple potential violations of the HIPAA Rules, including two violations of the HIPAA Security Rule. Lehigh Valley Health Network was determined to have failed to conduct a comprehensive and accurate risk analysis to identify risks and vulnerabilities to electronic PHI, and failed to implement policies and procedures for regularly reviewing records of activity in information systems containing ePHI, such as audit logs, access reports, and security incident tracking reports. These failures led to the impermissible disclosure of the ePHI of 248,359 individuals, in violation of the HIPAA Privacy Rule.

OCR also determined that Lehigh Valley Health Network failed to issue timely notifications to the affected individuals to alert them to the theft of their personal and health information and did not issue a timely notification to the Secretary of the Department of Health and Human Services, in violation of the HIPAA Breach Notification Rule. According to OCR, the intrusion was detected on February 4, 2026, and OCR was notified about the incident on May 15, 2026. The HHS Secretary must be notified about a breach of unsecured protected health information within 60 days of discovery of a breach. While OCR has not stated that it has an active enforcement initiative targeting noncompliance with the HIPAA Breach Notification Rule, a significant number of recent settlements have involved penalties for breach notification failures, including five of the 12 HIPAA settlements announced this year and five settlements last year.

Under the terms of the settlement agreement, in addition to the financial penalty, Lehigh Valley Health Network has agreed to adopt a corrective action plan that includes the requirements to conduct a comprehensive and accurate risk analysis, develop a risk management plan, review and revise its policies and procedures to ensure compliance with the HIPAA Rules, and develop training materials and provide training to its workforce on the HIPAA Rules relative to the performance of individuals’ job duties. OCR will monitor Lehigh Valley Health Network for compliance for a period of three years.

“Failure to conduct an accurate and thorough risk analysis and to undertake regular review of information system activity makes regulated entities attractive targets for cyberattacks,” said OCR Director Paula M. Stannard. “The best defense against cyberattacks is full implementation of the HIPAA Security Rule.”

Vendor Incident Affects 341,000 Blueberry Pediatrics Patients

Blueberry Pediatrics, a telemedicine service provider that offers subscribers access to board-certified pediatricians, has been affected by a data security incident involving a third-party tool called Metabase. The incident resulted in the theft of the sensitive data of 340,915 individuals.

Metabase, a business intelligence and data visualization platform used by more than 100,000 organizations, was found to contain a critical vulnerability. On August 22, 2026, Blueberry Pediatrics learned that the vulnerability had been exploited by a hacker who obtained a copy of patient data. Metabase was also used by Photon, a prescription service provider used by Blueberry Pediatrics, that exposed a subset of the same information. On August 24, 2026, Photon advised Blueberry Pediatrics that the vulnerability had also been exploited by a different threat actor, who also obtained a copy of patient data.

Blueberry Pediatrics has analyzed the impacted data and determined that the stolen data included patient information such as names, dates of birth, health plan names and policy numbers, medical records, dates of service, medical codes, and charges for services. Individuals impacted by the incident at Photon had their names, addresses, phone numbers, email addresses, member IDs, and/or medication information compromised. Blueberry Pediatrics has confirmed that photos and videos provided by patients were stored separately and were not compromised in the incident, and financial information and Social Security numbers were not involved.

Blueberry Pediatrics said immediate action was taken when it was notified about the vulnerability by Metabase and applied the patch to fix the vulnerability within hours; however, a threat actor already had access to its data. The access was immediately blocked, and after patching, passwords and security protocols were changed. Additional steps have been taken to harden security, including strengthening authentication controls, increasing the frequency of security reviews, and implementing an additional monitoring and escalation process for critical vendor vulnerabilities.

Because the same data was exposed in multiple incidents, some of the affected individuals are likely to receive more than one breach notice. The data breach is not currently shown on the HHS Office for Civil Rights breach portal; however, the Oregon Attorney General was informed that 340,915 individuals were affected. The Texas Attorney General received two breach reports, one involving the information of 60,581 state residents and the other affecting 7,249 state residents.

University of New Mexico Health System Diverts Ambulances Due to Ransomware Attack

The University of New Mexico Health System (UNM Health) has experienced a cyberattack that has prevented access to critical electronic systems. The incident was detected on October 26, 2026, and as a precaution to ensure patient safety, all ambulance traffic was temporarily diverted to alternative hospitals. A decision was made to cancel all appointments at UNM Health facilities on October 26. UNM Health explained in a 2:30 p.m. update on October 26 that it was also temporarily limiting the acceptance of new patients while efforts continued to restore access to key systems.

Other health systems in Albuquerque and Santa Fe have been working with UNM Health to ensure that patients receive the care they need. UNM Health operates UNM Hospital in Albuquerque, the only level 1 trauma center in New Mexico, so the cyberattack had the potential to place patient safety at serious risk. According to UNM Health’s announcement, the incident caused a system outage that affected the entire University of New Mexico Health Sciences Center. On October 26, all students at the School of Medicine, College of Pharmacy, College of Nursing, and College of Population Health were requested to leave the campus, and classes were also cancelled on Tuesday.

UNM Health was able to quickly start restoring access to systems, and confirmed in a 10:27 p.m. update that all UNM Health hospitals remain open, and clinics would resume regularly scheduled appointments on October 27, 2026. In the early hours of October 27, 2026, UNM Health confirmed that critical systems had been brought back online at The University of New Mexico Health Sciences Center, and ambulance traffic had returned to normal operations. The divert lasted from 12:30 to 2:30 p.m. on October 26. UNM Health said the cancellation of appointments and outpatient surgeries was necessary while IT teams worked to protect the network.

Containment efforts began at around 11 a.m. on October 26, which were largely successful. While some end user devices were impacted, UNM was able to prevent the threat actor from reaching its core systems and servers. External cybersecurity partners assisted with the remediation efforts, and an investigation has been launched to assess the nature and scope of the unauthorized access.

Law enforcement has been notified, and the incident is under criminal investigation, so limited information about the nature of the attack can be disclosed at this time. It is naturally too early to determine the extent to which patient data was involved. While UNM Health has not disclosed details about the nature of the attack, this appears to have been an attempted ransomware attack. A new ransomware group called Byod has claimed it was responsible. The group’s data leak site currently lists 10 victims.

The group’s post about the attack suggests that 36,000 systems at the UNM main campus and UNM Health were compromised, and that patient, student, and employee data was exfiltrated, along with payroll information, internal emails, and Cerner EHR rosters. The group later backtracked to a degree, adding a further post stating it was unaware that “[UNM Health] was running machines related to assisting patients in real-time,” and offered to provide certain decryption keys for free. “(we would keep it locked if it was appointments, patient information + research data only), we are still going to keep the data, but we will provide the decryption key for the hospital sector only… To any patient that was affected, we will pay you up to $2,500 each for the inconvenience. We are sorry once again. We have morals, and we have a heart, we are not villains, but we will still hold companies responsible for bad security leading to compromise of any customer data.”

Data Breach Announced by NorthShore Health Centers

NorthShore Health Centers, a nonprofit healthcare provider serving patients in Porter, Lake, La Porte, and Jasper Counties in Northwest Indiana, has warned patients about a cybersecurity incident that exposed some of their personal and protected health information.

According to its October 14, 2026, website notice about the data privacy event, the incident was first detected on August 10, 2026. An investigation was launched into suspicious network activity, with assistance provided by third-party cybersecurity and digital forensics experts. The investigation determined that an (unnamed) unauthorized third party had access to parts of its IT environment between August 10, 2026, and August 11, 2026, and potentially viewed or obtained files containing patient information.

The investigation and data review are ongoing as of October 14, 2026, so the number of affected individuals has not yet been confirmed. The types of information involved are still being assessed; however, it is likely that names, Social Security numbers, information related to medical treatments and conditions, and health insurance information were involved.

NorthShore Health Centers said it will mail notification letters to the affected individuals when the data review is concluded. Current and former patients should be aware that a ransomware group called Insomnia has claimed responsibility for the incident. The group added NorthShore Health Centers to its dark web data leak site and threatened to publish the stolen data if a ransom was not paid; it then proceeded to leak the stolen data. The HIPAA Journal has not downloaded any of the leaked data; however, the file tree suggests that patient data is likely included in the leaked dataset.
