Sector, country and ransom-demand figures are SecuritySnares estimates made with a language model. Leak-site listings are claims by threat actors and are not independently verified; leak-site victims are never named unless they have disclosed the incident themselves. News headlines are the publishers' own reporting, shown as written and linked to the original. Methodology
