Ransomware attacks have been announced by Glendale Obstetrics & Gynecology in Arizona and Lymphedema Therapy Specialists in Texas, and City Health in California has notified patients about a recent data breach.
Glendale Obstetrics & Gynecology
Glendale Obstetrics & Gynecology in Glendale, Arizona, has started issuing notifications about an October 2025 security incident. The incident was described as “network disruption affecting a portion of its digital environment,” terminology often used to describe a ransomware attack. The notification letters sent to state attorneys general do not state when the unauthorized access first occurred, only that it was detected on October 25, 2025.
The files on the compromised parts of its network were reviewed, and that process was completed on March 16, 2026. Data compromised in the incident varies from individual to individual and may include names plus one or more of the following: address, date of birth, Social Security number, driver’s license information, medical information, and health insurance information. The affected individuals have been offered complimentary credit monitoring and identity theft protection services for 12 months.
A ransomware group called Safepay claimed responsibility for the attack. SafePay engages in data theft and data encryption and claimed to have exfiltrated data in the attack. SafePay added Glendale Obstetrics to its data leak site on November 11, 2025, and then leaked the stolen data on its dark web site. Glendale Obstetrics reported the data breach to the HHS’ Office for Civil Rights on December 24, 2025, using a placeholder estimate of at least 501 affected individuals. State attorneys general have recently been notified, although the 501 total has yet to be updated on the OCR breach portal, so it is unclear how many individuals have been affected. Individual notification letters started to be mailed on April 9, 2026.
Lymphedema Therapy Specialists
Lymphedema Therapy Specialists (LTS), a Houston, Texas-based clinic providing lymphedema treatment, has recently announced a data breach. Unauthorized network activity was identified on February 11, 2026, and a third-party digital forensic investigation confirmed that its network was accessed by an unauthorized third party who may have viewed or copied patient information.
The compromised parts of its network were reviewed, and on February 18, 2026, LTS confirmed that patient and employee information had been exposed, including names, Social Security numbers, government-issued identification numbers, workers’ compensation information, medical information, and health insurance information.
While not described as a ransomware attack, a ransomware group claimed responsibility for the incident. The INC Ransom group added LTS to its dark web data leak site and claimed that personally identifiable information and protected health information were stolen in the attack, in addition to organizational data. Based on the substitute breach notice on the LTS website, credit monitoring and identity theft protection services do not appear to have been offered. It is currently unclear how many individuals have been affected in total. The Texas Attorney General was informed that 378 Texas residents were affected.
City Health
City Health, a California healthcare provider with locations in San Leandro and Oakland, has notified certain patients about a hacking incident that was identified on March 30, 2026. Assisted by third-party cybersecurity specialists, City Health determined that an unauthorized third party accessed its network between March 2, 2026, and March 11, 2026, and viewed or acquired files containing sensitive information.
Data accessed in the incident included names, insurance provider names, and procedure codes only. City Health said contact information, dates of birth, and Social Security numbers were not involved. The incident was rapidly reported to regulators, including the California Attorney General, who was notified about the incident on April 13, 2026, just two weeks after the breach was first identified. Individual notification letters are now being sent to the affected individuals.
City Health is reviewing its security practices, policies, and procedures, and is taking steps to prevent similar incidents in the future. While data has been exposed, City Health is unaware of any actual or attempted misuse of the exposed data. “We apologize for any inconvenience and concerns this may cause you,” City Health’s management team said. “City Health would like to assure you that we have handled the situation swiftly and have taken necessary steps to ensure that it will not happen again.” 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.
