A multinational biopharmaceutical company, Amgen Inc., has suffered a data breach involving patient protected health information (PHI) and proprietary company data. In July 2026, Amgen identified unauthorized activity in cloud environments hosted by third-party providers.
The company's cybersecurity response plan was activated, containment measures were initiated, and forensic experts were engaged to investigate the incident. The investigation confirmed that attackers had exfiltrated data from the cloud environments, including PHI and proprietary company data.
Amgen disclosed the breach in a Form 8-K filed with the U.S. Securities and Exchange Commission on July 31, 2026. The information exposed in the Amgen data breach includes patient protected health information and proprietary and confidential company data.
