How the check works

1 · Collect

Ransomware crews post the names of organisations they say they hit. Public trackers record those posts and we pull them into our graph every few hours.

2 · Match

A website match is the strongest. Then an exact name match, ignoring "Ltd" and "Inc". Similar names are shown as unconfirmed and never as a hit.

3 · Tell you straight

A claim is not proof of a breach, and no claim is not proof of safety. We say which one you are looking at, and when it was posted. One known limit: our records are thin from June 2025 to March 2026, so a claim from those months may be missing.

Want every supplier checked every day, with an alert when a new claim lands? That is Supply Chain Sonar. For the bigger picture, see the most active crews and the Ransom Index.
