Amgen Hit by Data Breach Exposing Patient Health Info in Cloud Hack

California-based biotechnology company Amgen has revealed that hackers breached its third-party cloud systems in July 2026, stealing sensitive data and patient health information. The company detected the unauthorized activity and immediately activated its cybersecurity response plan to contain the breach.

The investigation found that attackers extracted data from the affected cloud environments, including proprietary information, patient protected health information, and other sensitive details. Amgen is still working to determine the full extent of the breach, including whether additional material was accessed or taken.

The company has not named the third-party cloud providers involved or disclosed how many individuals may be affected by the breach. Despite its severity, Amgen believes that the incident will not have a material effect on its financial condition or operating results.

Amgen's disclosure comes as the healthcare and pharmaceutical industry faces growing concerns over cyberattacks. The company is reviewing its legal and regulatory notification obligations to determine whether it must notify affected patients.
