Breach coverage goes wrong in two directions: inflating an exposure into a certainty, or burying it. We publish the disclosed numbers, name the source, and mark clearly where an investigation is still open and the count may change.

Most people find out from a letter weeks after the fact. These are the steps that still work at that point, in the order they should be done, with what each one does and does not protect.
Primary sources: the breached organization's own notification letter, filings in state Attorney General breach databases, the U.S. Department of Health and Human Services breach portal for healthcare incidents, SEC filings, court records and regulator announcements. Where we cite a figure, that figure comes from one of those documents.
Not necessarily, and the difference matters. Most notices state that an unauthorized party accessed or acquired data. That is a different finding from evidence that the data has been used for fraud. We report which one a given notice supports, and we do not fill the gap with speculation.
No. Only the organization that holds your records can confirm that, and it is required to notify you. What we can do is tell you what was disclosed, who the claims administrator or notification contact is, and what steps are worth taking while you wait.
No. Data Breach Radar is independent reporting. Nothing on this site creates a professional relationship or substitutes for advice from a lawyer, a security professional or your bank. Always verify details against the notice you received.
The site is free to read and carries advertising. Some pages may contain affiliate links, which are disclosed on our Affiliate Disclosure page. Advertisers and affiliate partners have no input into what we cover or what we say about it, and we do not accept payment to include, exclude or soften a breach report.
