What we know

Amgen Inc, a leading biotechnology and pharmaceutical company, has reported a data security incident to the Indiana Attorney General, with a filing date of August 17, 2026. If you have received a notification letter from Amgen, it means your sensitive personal information was part of this compromise.

The reported exposed data includes Full Name, Date of Birth, Social Security Number, Clinical Trial Participation Records, Medical History and Treatment Information, Health Insurance ID Number, Mailing Address, and Email Address. This combination of identifiers and health data presents a serious threat to your privacy and security.

Attackers who gain access to this type of information can engage in various forms of fraud. Medical identity theft, where criminals use your health insurance details for their own care or to file false claims, is a significant concern. The exposure of your Social Security Number and Date of Birth can also pave the way for broader identity theft, including opening fraudulent accounts, tax fraud, or sophisticated phishing attempts designed to steal more personal data or money.

As a company handling vast amounts of confidential personal and health information, Amgen Inc had a legal obligation to implement robust security measures to protect this data. The occurrence of this data breach suggests potential weaknesses or failures in these protective systems, which are mandated by various state and federal regulations.

Receiving an official notification letter from Amgen Inc confirms that your information was impacted. It's crucial to understand what this means for you and to consider your options. Taking proactive steps, such as monitoring your credit reports and reviewing medical statements for suspicious activity, is highly recommended.

After the Amgen Inc incident: what to do and your options

What should I do after getting the Amgen Inc data breach notice?

The filing does not give a count of affected people and lists the following information as involved: Full Name, Date of Birth, Social Security Number, Clinical Trial Participation Records, Medical History and Treatment Information, Health Insurance ID Number, Mailing Address, Email Address. Your own letter is the best guide to what was exposed about you, since notices are usually tailored to each person.
Did Amgen Inc offer free credit monitoring?
Check your letter from Amgen Inc. If free credit or identity monitoring is offered, the enrollment code and deadline are printed in the notice itself. Because Social Security numbers are listed in this filing, identity monitoring and a credit freeze matter more than usual.
