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 183 claims across 32 groups, 171 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.

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.

Watch for your own name

Tell us what to watch for and we will email you when a group claims it. Weekly at most, only when something matches, and never the same claim twice. Double opt-in, one-click unsubscribe, and your watch list is deleted the moment you leave.
