Compare the organization, dates, and information categories with any notice you received. Use contact details you independently confirm.

Review your credit reports and consider a free credit freeze if identity information could support new-account fraud.

Review financial accounts

Check statements for unfamiliar activity and contact the card issuer or financial institution through an independently verified channel.

Expect targeted phishing

Treat unexpected breach follow-ups with caution. Do not use links or phone numbers in a suspicious message; contact the organization directly.
