How we research this Report an error

What was exposed

HHS lists names, addresses, dates of birth, Social Security numbers, claims information, medications and other treatment information. FreightWaves reports Navistar said a subset of people had their Social Security numbers exposed.

If your Social Security number was included, someone could use it with your date of birth to apply for credit or file a fake tax return. Claims and medication details are a hook for phishing that mentions your health plan or pharmacy.

The company's response

Navistar offered free credit monitoring and added administrative, technical and security safeguards, per HHS. OCR provided technical assistance. A class action was filed in federal court in Illinois in October 2021, FreightWaves reported.

What to do if you were in it

  1. 1

    Freeze your credit at all three bureaus

    A credit freeze is free and stops lenders from opening new accounts in your name. Place one at Equifax, Experian and TransUnion, as the FTC explains. Do this if your letter says your Social Security number was involved.

  2. 2

    Use the free credit monitoring if you were offered it

    The notice letter explains how to enrol, and there is a deadline. The FTC recommends taking free credit monitoring when a company offers it. Enrolment is separate from a freeze, so do both.

  3. 3

    Read your insurance and medical statements

    Check the statements from your health insurer and your health plan. Report treatment, claims or bills you don't recognize to the insurer, since someone may be using your details to get care.

  4. 4

    Be wary of messages that mention the breach

    Scammers use real details to sound credible. Don't click links or call numbers in unexpected texts, emails or calls about your health plan, retiree benefits or the breach. Go to the organization's own website instead. If you spot a scam, report it at IdentityTheft.gov.

  5. 5

    Check whether your email or phone is in other breaches
