USA government and public sector

All 787 →

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. Recent Breaches and GalaxyWarden are independent and are not affiliated with, and do not endorse, any company or group named on this page. This information is aggregated from public sources for awareness only and is not legal, security, or investment advice.

USA data breaches: common questions

How many data breaches have been reported in the USA in 2026?

We are tracking 5985 US incidents dated in 2026, out of 18828 US incidents in total. That is what this tracker holds, not a national total: no public source sees every breach, and US disclosure law varies by state, so any figure is a floor rather than a count.

Where does this USA breach data come from?

US state Attorney General breach-notification registries, SEC Form 8-K cybersecurity disclosures, CISA advisories, Have I Been Pwned, and ransomware leak sites. Filings and disclosures are treated as confirmed and lead the page; leak-site listings are claims made by the group that says it carried out the attack and are labelled as claims throughout.

Is a ransomware leak-site listing proof of a breach?

No. A listing is an allegation published by an extortion group on its own site, usually to pressure a victim into paying. It is not confirmation that a breach occurred, that the data is genuine, or that any particular records were taken. We publish these because they are often the first public signal, and we label them.

What is the biggest USA data breach this year?

The largest confirmed US breach in our records this year is AT&T Inc., with about 51.2 million people affected. That is the largest we can point to a filing for — unverified leak-site claims are excluded from this answer because a claim is not a count.

How do I find out if my own data was in a USA breach?

Search this tracker for the company by name, or run a free scan of your email address against known leaked records to see every breach it appears in.
