Confirmed breaches and unverified leak-site claims in one labeled feed. Confirmed breaches come from the California Attorney General breach portal, the Department of Health and Human Services Office for Civil Rights (HHS OCR, including its 42 CFR Part 2 substance-use records), Securities and Exchange Commission (SEC) 8-K cyber-incident filings, and the Have I Been Pwned breach directory. Leak-site claims come from RansomLook and, as a failover, ransomware.live. Claims are always labeled and never presented as fact.

Of 13,190 confirmed breaches, 5,328 come from the California Attorney General portal, which publishes no individuals-affected count. Those rows, and any other government-source row whose portal did not publish a count, read "Not reported" here (5,329 in all): the source's own gap, not omission on our part.
Filter to "Removed from leak site" to surface victims a ransomware group has taken off its own leak site. A removal can signal that the incident was resolved or the ransom paid, but a group can also remove a victim after a fake or withdrawn claim, or by taking down its own site, so it is an observation only, never a guarantee or confirmation of payment.

Per-incident affected-count reconciliation across government breach sources is not currently possible. The Maine Attorney General portal has been offline since 2026-06-12, and the California Attorney General publishes no affected-persons count. Where one incident is reported to more than one source it is cross-linked, and every count shown is only the number that source itself reported.
A "No longer listed" badge means the victim was present on the leak site and is now absent from the claiming group's current listing, confirmed across two consecutive checks. It is an observation only. It is not a confirmation that the organization paid, negotiated, or resolved the incident, and a group that takes down its own site can cause it. Removal is tracked for RansomLook claims, the only source that publishes a full per-group listing. A claim from another source carries no badge because its removal is not tracked, which is not evidence the victim is still listed.
