DARKSIDE_

Dormant

DarkSide was a ransomware-as-a-service operation that briefly dominated headlines in 2021 after one of its affiliates carried out the Colonial Pipeline attack. Faced with US government attention, the operators announced a shutdown and rebranded — successor activity attributed to BlackMatter and ALPHV/BlackCat is widely traced back to the same operators.

Ransomnews coverage of DarkSide

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