Who may be affected?
This record may be relevant to people who had an account or other relationship with diet.com or used diet.com around August 10, 2014. A catalogue entry does not establish that every customer was affected or that every listed data category applied to each person. Compare the record with an official notice addressed to you.
What should you do?
Compare the organization, dates, and information categories with any notice you received. Use contact details you independently confirm.
Change exposed or reused passwords, begin with your email account, and turn on multi-factor authentication where available.
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.
