Recent Data Breaches in the USA

Every US data breach, ransomware listing and regulator filing we track, updated daily. Confirmed filings lead; unverified leak-site claims are marked.

Sourced from US state Attorney General breach notifications, SEC Form 8-K disclosures, CISA advisories and ransomware leak sites. Incidents we cannot place in the USA stay on the global tracker rather than being assumed American.

Incidents a company or a regulator has put on the record — state Attorney General breach notifications and SEC Form 8-K disclosures. These are the ones with a named, accountable source.

Listings posted by extortion groups on their own leak sites. A listing is an allegation by the attacker and nothing more — it is not confirmation that a breach occurred, or that any particular data was taken.

Federal agencies, state government, cities and counties, school districts and public universities — tracked separately because the public has a different stake in them.

Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
