Amgen Data Breach Exposes Patient Health Info, Proprietary Company Data

Amgen, a California-based biopharmaceutical company, has reported a data breach that exposed patient protected health information and proprietary company data. The incident occurred in July 2026 when Amgen identified unauthorized activity involving data stored in cloud environments hosted by third-party providers.

After activating its cybersecurity response plan, Amgen engaged forensic experts to investigate the breach. Their findings confirmed that attackers had exfiltrated data from the cloud environments, including proprietary company data and patient protected health information.

The breach may affect patients whose protected health information was stored in the affected cloud environments. Individuals who receive a data breach notification from Amgen may face an increased risk of medical identity theft and fraud.
