Rehabilitation Support Services

Rehabilitation Support Services, also known by its alias, is a provider of psychiatric and substance abuse support services operating across multiple New York counties. The organization is headquartered in the United States of America. It delivers behavioral health care to individuals experiencing mental health challenges and substance use disorders. Its service footprint includes outreach to vulnerable populations such as children and residents of nursing homes. The organization handles a range of sensitive information in the course of its work, including health insurance details, medical certifications and personally identifiable data.

In June 2021, a threat actor identified as "Grief" reportedly breached Rehabilitation Support Services, exfiltrating about four gigabytes of data that included internal documents, financial records and the aforementioned personal information. The actor threatened to release the data incrementally unless the organization responded, although no file encryption was confirmed. Rehabilitation Support Services did not publicly acknowledge the incident or reply to inquiries, leaving the exposed data potentially accessible to affected clients and employees. The breach highlighted the organization's role as a custodian of confidential health‑related records and underscored the risks associated with insufficient public communication after a security event. No explicit details about the organization's ownership, parent company or subsidiary structure are provided in the available sources.
