In July 2026, AdaptHealth, a home medical equipment provider, suffered a material data breach resulting from a targeted social engineering campaign. The threat actor successfully bypassed security controls by deceiving personnel to obtain valid user and administrative credentials. This unauthorized access facilitated entry into the company's internal patient management systems, where sensitive Protected Health Information (PHI) was exfiltrated through unauthorized channels. The severity of the breach necessitated an SEC 8-K filing. The incident has triggered substantial legal and regulatory risks, including multiple class-action lawsuits and potential HIPAA-related enforcement actions.

• Incident/Breach Overview
