July 31 (Reuters) – Drugmaker Amgen said on Friday hackers ​stole company data ‌and patient health information in a cybersecurity breach involving cloud ‌storage ​systems ⁠run by third-party ⁠providers.

On July 29, Amgen determined the incident was material, based ​on its evaluation of how ⁠many ⁠files appeared to ​be affected and the ​possibility that the information ‌in those files could be sensitive, it said ⁠in a regulatory filing.

The company has activated its ⁠cybersecurity ‌response plan, put ⁠containment measures ​in ‌place, and brought ​in independent ⁠forensic experts to investigate.
