Patient & Employee Data Exposed in Baylor Genetics Cybersecurity Incident

Baylor Genetics, a clinical diagnostic genomics company, has recently disclosed a cybersecurity incident that has exposed patient and employee data. The incident was first announced in June; however, the extent of the data breach was unclear at the time.

Baylor Genetics provides genetic testing services to hospitals and is headquartered at the Texas Medical Center in Houston.  The company identified suspicious activity within its computer network on or around June 15, 2026. Immediate action was taken to secure its systems, and an investigation was launched to determine the cause of the activity.  The investigation determined that an unauthorized third party accessed a portion of its information technology network between June 11 and June 17, 2026, and viewed or obtained data stored on the network.

Assisted by third-party cybersecurity specialists, Baylor Genetics conducted a detailed and time-intensive review of all potentially impacted files. The review was completed on July 30, 2026, when it was confirmed that the personal information of certain patients and employees was involved. The types of data involved varied from individual to individual and may have included names plus one or more of the following: date of birth, medical testing information, lab test results, health insurance information, and for a limited subset of patients, Social Security numbers.

Employee data was also exposed in the incident, including personally identifying information such as Social Security numbers, government-issued identification numbers, and financial account information. While data was exposed and potentially exfiltrated, Baylor Genetics is unaware of any actual or attempted identity theft, fraud, or other misuses of the impacted data.

Baylor Genetics said the incident did not impact its laboratory operations, which continued without interruption throughout the investigation, and there was no impact on the company’s ability to provide genetic testing services. Baylor Genetics has enhanced its security and monitoring controls, strengthened identity and access management, and has implemented additional security controls to prevent similar incidents in the future.  Complimentary credit monitoring and identity theft protection services have been offered to at least some patients.

The data breach has been reported to regulators; however, it is currently unclear how many patients and employees had data compromised in the incident. The breach has affected patients in California, as the California Attorney General was notified about the data breach, as was the Vermont Attorney General. At least 2,630 Vermont residents have been affected.

Regional Center of Orange County, California

Regional Center of Orange County, a Santa Ana, California-based nonprofit organization that provides services to approximately 29,000 Orange County residents with autism, epilepsy, cerebral palsy, and intellectual and cognitive disabilities, has announced a data security incident that has exposed sensitive data. The incident involved paper records that were mistakenly disposed of by a Janitorial service contracted to clean its Cypress office. The incident occurred on May 27, 2026, and was discovered on May 28, 2026. Documents had been disposed of in regular trash bins rather than being sent for secure destruction. Attempts were made to retrieve the documents; however, the trash had already been collected.

It was not possible to determine the exact patients involved or the specific types of information, so notification letters have been sent to all individuals who received services at the Cypress office.  Data likely exposed included names, addresses, birth dates, phone numbers, email addresses, unique client identifiers, and personal health information. Regional Center of Orange County said it is reviewing and strengthening internal procedures, staff training, and vendor oversight to prevent similar incidents in the future, and the affected individuals have been offered complimentary credit monitoring and identity theft protection services.

Vishing Attack Provides Threat Act with Access to Quantum Health Network

Data breaches have recently been announced by the healthcare navigation and care coordination company Quantum Health, Heart of America Medical Center, and Precision Imaging Centers.

Quantum Health

Quantum Health, a Dublin, Ohio-based healthcare navigation and care coordination company that helps self-insured employers manage employee benefits and lower healthcare costs, has disclosed a cybersecurity incident that it identified in May 2026.

The incident started with a vishing attempt. The attacker called a Quantum Health user on May 29, 2026, and tricked them into providing access to the Quantum Health network. Between May 29, 2026, and June 1, 2026, the unauthorized third party had access to its network and acquired files. On June 1, 2026, Quantumn Health experienced a network disruption affecting both internal and external systems. An investigation was launched, which traced the incident back to the vishing call. The threat group behind the incident was not named, and no ransomware group appears to have claimed responsibility for the attack. These tactics are commonly used by the ShinyHunters threat group, which was the subject of a recent Health-ISAC cybersecurity alert.

On June 8, 2026, Quantum Health confirmed that the exfiltrated data included personal and protected health information, including names, addresses, email addresses, phone numbers, dates of birth, demographic information, Social Security numbers, diagnosis and treatment information, prescriptions, provider names, dates of service, insurance information, and claims or benefits information.

Aesto Health Data Security Incident Affects Multiple Healthcare Provider Clients

A data breach at Aesto Health, a Birmingham, Alabama-based healthcare technology company, has affected several of its healthcare provider clients. Aesto Health provides secure data migration, legacy data archiving, and electronic health record (EHR) exchanges for medical practices and healthcare enterprises. According to its announcement, a security incident was identified on or around December 18, 2025, involving part of its Amazon Web Services (AWS) infrastructure. Third-party cybersecurity experts were engaged to investigate the incident and confirmed that its AWS environment was accessed by an unauthorized third party between December 2 and December 18, 2025.

The affected parts of its infrastructure were reviewed and confirmed to contain personally identifiable information and protected health information, including full names, Social Security numbers, partial dates of birth, driver’s license numbers, state identification numbers, financial account numbers, taxpayer identification numbers, health records, medical histories, claims/billing information, and health insurance information. Aesto Health said it had taken many precautions to safeguard the sensitive data in its possession and continually evaluates and modifies its security practices. Credit monitoring and identity theft protection services have been made available.

The incident is known to have affected more than two dozen of its healthcare provider clients. They started to be notified on June 26, 2026. Whenever there is a data breach at a business associate of a HIPAA-covered entity, the affected covered entity is ultimately responsible for ensuring that the requirements of the HIPAA Breach Notification Rule are met. The covered entity may delegate the responsibility for issuing notification letters to the breached business associate, or it may choose to issue notification letters itself. As a result, it is often difficult to determine how many individuals have been affected by a business associate data breach, although in this case the breach has certainly affected hundreds of thousands of patients.

Based on state Attorney General breach listings, at least 80,622 South Carolina residents, 37,253 Washington residents, 731 Oregon residents, and 91 Vermont residents have been affected; however, many of the affected clients have chosen to report the breach themselves. In some cases, clients report that tens of thousands of their patients have been affected. For instance, Village Practice Management has confirmed that more than 25,000 of its patients have been affected, and Everside Health informed the Washington Attorney General that approximately 22,000 individuals have been affected in Washington alone.

Strict Rules Set for Change Healthcare Dataset in Multidistrict Litigation

The volume and sensitive nature of the data stolen from Change Healthcare in its 2024 ransomware attack have led to strict rules being established for data handling by attorneys involved in a consolidated lawsuit against United Health Group (UHG), Change Healthcare, Optum, and other UHG subsidiaries. The rules will help to ensure that the dataset is protected at all times.

The ransomware attack resulted in the theft of approximately 6 terabytes of data, including files containing the electronic protected health information of an estimated 192,700,000 individuals, including names, contact information, Social Security numbers, driver’s license numbers, insurance information, and medical information. UHG paid the BlackCat ransomware group a $22 million ransom to delete the data; however, the operators pocketed the cash and didn’t pay the affiliate, who had retained a copy. The affiliate joined another ransom group, RansomHub, which attempted to extort UHG a second time.

This was the largest-ever healthcare data breach by some distance, and triggered dozens of lawsuits, including class action lawsuits filed by patients who had their data stolen and healthcare providers seeking compensation for the financial and operational disruptions they experienced. On June 7, 2024, the Judicial Panel on Multidistrict Litigation consolidated an initial 49 lawsuits, including 19 consumer complaints and 30 healthcare provider complaints, although the number of lawsuits included in the action has grown to more than 150. The consolidated lawsuit – In Re: Change Healthcare, Inc. Customer Data Security Breach Litigation – was centralized in the U.S. District Court for the District of Minnesota.

The stolen data files are designated discovery material, and due to the sensitive nature of the data and the volume of records, heightened security practices are required to protect against unauthorized access and data theft. The rules concerning the stolen dataset were approved by the plaintiffs’ attorneys and were verified by a cybersecurity expert as being sufficient to ensure the security of the data before being sent to the judge for approval. The stipulated protective order has recently been approved by Magistrate Judge Dulce Foster.

UHG will provide a single copy of the data on an encrypted hard drive built to a federal security standard, and must provide the key to decrypt the data separately, to ensure that in the event of loss or theft of the drive, the data cannot be accessed. The plaintiffs’ attorneys are required to encrypt the data again once they have received the hard drive, using industry-standard encryption. No copies may be made of the data, and the data cannot be saved to the shared file library used by all individuals involved in the case. The plaintiffs’ attorneys are prohibited from using the dataset to identify or locate potential class members.

The hard drive must only be used on computers that are air-gapped – disconnected from the Internet and all networks, with no Wi-Fi or Bluetooth connectivity. The computers must be newly provisioned and updated prior to use, and when the computers are used, no cables, phones, or storage devices are permitted nearby.  When data access is required, only small samples may be accessed, and no more than 25 people are permitted access at any one time. All samples must be encrypted with strong encryption and a complex password set of at least 16 characters.

An audit trail must be maintained, including a detailed chain of custody of the drive and data, and the log must be provided to UHG on request. When the case ends, or if the plaintiffs’ claims are thrown out, the data must be securely destroyed within 30 days, using a government-approved data wiping method – NIST SP 800-88 – or the hard drive must be physically destroyed, and a detailed certificate of destruction obtained under penalty of perjury.

In the event of a security incident or unauthorized data access or data sharing, UHG must be notified within 48 hours. Should it turn out to be a genuine security incident, both sides are required to engage an external digital forensic firm, and if the plaintiffs are found to be at fault, they must pay the full investigation costs.
