Gilead Sciences Data Breach: Lawsuit Investigation

Attorneys working with ClassAction.org are looking into whether a class action lawsuit can be filed in light of the data breach impacting Gilead Sciences.

As part of their investigation, they need to hear from individuals who received a notice stating they were affected.

Trusaic Security Incident: What Happened?

Gilead Sciences, Inc. has reported a data breach involving personal information provided to Trusaic, a software company that assists clients like Gilead with Affordable Care Act compliance and reporting services.

Trusaic explained in letters sent to affected individuals (an example of which can be seen below) that the breach involved its mailing distribution vendor, Billing Document Specialists (BDS). According to the notice, BDS inadvertently mailed 1095-C tax forms with shipping labels displaying an 18-digit string that included the recipient's Social Security number. The batch of forms was mailed on February 7, 2025.

The data breach, discovered by Trusaic on February 18, 2025, prompted the company to undertake a review and collaborate with BDS to enhance security measures. Trusaic's review confirmed that there was no unauthorized access to its customer databases or internal servers.

Gilead Sciences reported that the data breach impacted 12,224 people.

What You Can Do

If your information was exposed in the data breach, attorneys want to hear from you. You may be able to start a class action lawsuit to recover compensation for loss of privacy, time spent dealing with the breach, out-of-pocket costs, and more.

A successful case could also force Gilead Sciences to ensure it takes proper steps to protect the information it was entrusted with.
