Every figure in this report counts a claim posted to a criminal leak site, observed via the monitoring service ransomware.live. A listing is an extortion tactic, not a confirmed breach: some claims are exaggerated, some are duplicates under new branding, and a few are outright false. Companies named in listings have not necessarily confirmed any incident, and ThreatVectr does not publish victim names from this dataset.
