Methodology
Counts are victims publicly claimed on ransomware leak sites, as aggregated from ransomware.live, and are dated by the claim’s publication date (UTC). Claims are made by the criminal groups themselves and are not independently verified; a listing does not confirm that an attack took place or that data was stolen. Shares are calculated against the month’s total of 465 victims, and sector and country fields reflect what was disclosed in each listing. See our methodology for details.
