Ransomware leak tracker.

Who ransomware groups are claiming to have breached, from two independent trackers of their leak sites. Unverified criminal claims, not confirmed breaches: an early signal to go and check, never a finding. Get alerts when something on your watch list is claimed. We do not record what you look up.

Tracking 2,073 claims across 108 groups, 237 of them in the last seven days.

Read this before you act on anything here

A listing means a criminal group has said it holds data from an organisation. It does not mean a breach happened, that the data is real, or that it is recent.

Groups fabricate. In April 2026 the group 0APT listed rival gangs as victims; the claims were invented. Removing them turned a reported 15% quarterly rise in attacks into a 6% fall.
Groups recycle. CISA has documented actors buying previously stolen data to re-extort. One study found 98 listings covering only 49 distinct victims.
Attribution is often wrong. Suppliers get listed as their customers, and shared domains get listed as the wrong organisation entirely.
It undercounts. The NCSC notes victims who pay never appear on a leak site at all.

Where two independent trackers carried the same claim we mark it 2 sources. That means two crawlers saw the same post, not that anyone verified it.

We publish the claim only. We do not link to leak sites, mirror screenshots, or carry any pointer to stolen data. If you are listed here and believe it is wrong, or you want the entry removed, tell us and we will act on it.

None of this is our research. The crawling is done by RansomLook, Ransomfeed and ransomware.live, and we are grateful for it. Please go to them for the full picture.
