What happened

Idaho National Laboratory experienced a targeted cyberattack on its computer systems in December 2023. Files containing private information such as full names, Social Security numbers, dates of birth, and medical treatment and health insurance information were accessed. The defendant denies wrongdoing and the court has not decided the case; the parties settled to avoid litigation costs and risks.

Common questions

What is the claim deadline for the Idaho National Laboratory Data Breach Settlement?
This settlement is closed to new claims — the deadline was February 28, 2026. Once a claim deadline passes you generally forfeit your share, even if you qualified.
Is the Idaho National Laboratory Data Breach Settlement notice real, or a scam?
Claims are filed at inldatasettlement.com. Filing a class action claim is always free — no legitimate settlement charges you to claim, and no administrator will ask for payment, a gift card, or your full Social Security number by email or text. If a notice asks for any of those, it is not from the administrator. When in doubt, ignore the link you were sent and go to the official settlement website directly.
When will payments from the Idaho National Laboratory Data Breach Settlement be sent?
Class action payouts typically take 12 to 24 months after the claim deadline, and longer if the settlement is appealed. The final approval hearing for this case is set for March 20, 2026; no payments can be issued before a settlement receives final approval.
