235 GB of PHI and internal documents dumped; Chaos claims it comes from Healthcare Highways
The Chaos ransomware-as-a-service group posted 235 GB of protected health information and internal documents from Healthcare Highways to its leak site on August 5, 2026, with a 24-hour countdown timer. Healthcare Highways is a medical provider network company offering hospital and physician-based solutions to businesses and employees. The Chaos group, active since March 2025, claims responsibility for the data theft.
Why it matters: Healthcare organizations and their business partners face exposure of sensitive patient data and operational documents; security teams should verify whether their organization or supply chain partners are affected and prepare incident response and notification procedures.
