Change Healthcare, a critical healthcare technology provider, fell victim to a **SocGholish (FakeUpdates)**-driven cyberattack in early 2025, facilitated by the **RansomHub ransomware**. The attack originated from malicious Google Ads impersonating **Kaiser Permanente’s HR portal**, exploiting SocGholish’s Malware-as-a-Service (MaaS) infrastructure. The breach led to severe operational disruptions, including compromised patient data, financial records, and healthcare service outages. The incident was part of a broader campaign targeting healthcare entities, with **Evil Corp (a Russian cybercrime group linked to GRU Unit 29155)** involved in distributing payloads like **Raspberry Robin worm**. The attack crippled Change Healthcare’s systems, delaying medical treatments, disrupting payment processing for hospitals and pharmacies (e.g., **Rite Aid**), and exposing sensitive personal and financial information of patients and employees. The fallout included **ransom demands**, regulatory scrutiny, and long-term reputational damage, underscoring the threat’s capacity to weaponize trusted digital infrastructure for large-scale exploitation.
