How these trackers work

Our breach ingest monitors public reporting and ransomware leak sites daily. When an incident is claimed by or attributed to a named group, it's added to that group's tracker automatically. "Claimed by" is not proof — extortion crews sometimes exaggerate or recycle old data — so every entry links to the full write-up with sources.

If an organization you use appears here

Treat your data as circulating. Stolen records get scraped into the same broker-and-dump ecosystem that doxxers and identity thieves search. The fastest way to know your real exposure is a free breach scan — it checks your email against 13.1B+ leaked records in about 15 seconds, including data tied to the groups above.

Close the chain attack

Your email leaked. See who’s selling your address.

Nobody can unleak a breach. But the people-search sites selling your address because of it? Those come down. The free scan shows you which ones have you, in 15 seconds. Then you pick what fits.
