Sedgebrook Data Breach Affects 3 Massachusetts Residents

Sedgebrook, a senior living and skilled nursing company based in Illinois, experienced a cyberattack. On May 5, 2025, the company became aware of suspicious activity within its internal network. An investigation revealed that an unauthorized actor accessed the the Sedgebrook network from May 4, 2025 to May 5, 2025 and may have obtained sensitive files.

A review was completed on Aug. 26, 2025 and determined that the compromised files contacted both personally identifiable information (PII) and protected health information (PHI). Exposed information included names, addresses, dates of birth, Social Security numbers, driver’s license numbers, financial account numbers, medical treatment information, medical record numbers and health insurance policy information.

Sedgebrook began notifying affected individuals by mail on Oct. 24, 2025 and published a Notice of Data Incident on its website.

The data breach was also disclosed to the Massachusetts Attorney General's office on Oct. 23, 2025.
