THREAT ACTOR
BLACKWATER_
ActiveBLACKWATER is a ransomware operator tracked through its public data-leak infrastructure. The group operates under the double-extortion model that defines the modern ransomware ecosystem: file encryption combined with the threat of stolen-data publication on a public leak site. It continues to post fresh victim claims as part of an ongoing extortion campaign.

Claimed vs confirmed. The figures above the fold on this page come from Blackwater'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.
