Pharmaceutical company Amgen says it suffered a data breach after threat actors stole corporate data and patient information stored in multiple cloud systems operated by third-party service providers.
Amgen is a California-based biotechnology company that develops and manufactures medicines for serious illnesses, including cancer, cardiovascular disease, inflammation, and rare diseases.
The company said it detected the unauthorized activity in July 2026 and responded by activating its cybersecurity response plan, implementing containment measures, and hiring independent forensic experts to investigate the incident.
The investigation found that the attackers stole sensitive data from the cloud environments.
"The Company has since learned that some of its data, including proprietary data, patient protected health information, and other information, has been exfiltrated from these cloud environments," Amgen said in a Form 8-K filing with the SEC.
