What should you do?
Compare the organization, dates, and information categories with any notice you received. Use contact details you independently confirm.
Check statements for unfamiliar activity and contact the card issuer or financial institution through an independently verified channel.
Treat unexpected breach follow-ups with caution. Do not use links or phone numbers in a suspicious message; contact the organization directly.
Choose actions that match the information involved. If you find signs that someone is using your identity, the Federal Trade Commission provides a personal recovery plan at IdentityTheft.gov.
