Claimed vs confirmed. The figures above the fold on this page come from Argonauts Group's own leak-site postings and reflect what the operation claims. The table here is a separate evidence class: incidents Ransomnews verified against a public source. Confirmed counts are lower than claimed counts by design: most victims never disclose, and some leak-site listings are recycled, exaggerated or fabricated. Records and ransom figures are shown only where a named source disclosed them. See the full ransomware statistics or the Ransomtracker dataset.
