Amgen announced on July 31 that a data leak enabled hackers to obtain company files—including patient health information—in an incident involving cloud storage systems managed by third‑party vendors. In a regulatory filing, the company said it designated the incident as “material” on July 29 after assessing the number of files involved and the possibility that those files contained sensitive data.
– What the regulatory filing reveals
The filing states that the decision to deem the event material was based on the apparent scope of affected files and the potentially sensitive nature of the information they contain. Beyond that assessment, the filing does not provide numeric details on the exact number of compromised files or the identities of any potentially affected patients.
– Amgen’s response to the breach
Amgen activated its cybersecurity response plan, implemented containment measures, and engaged independent forensic experts to conduct an investigation. (The source text provided ends mid‑sentence.)
