A dated ledger of actor-claimed victims, campaigns, indicators, identity mappings, relationships, and CVE links. Each date states what it measures. For extensive leak-site histories, victim entries are limited to the 100 most recent distinct listings.
The cited upstream records use spacing or punctuation variants of the same actor name. Source records remain separate for provenance, while exact-name resolution prefers the reviewed canonical profile.
HighTypes: onion.
Exact names and tracking identifiers resolve to this canonical profile. Rebrands, affiliations, and overlapping clusters remain separate confidence-rated relationships.
Every exact-name collision is reviewed. Same-actor decisions select a preferred profile while distinct and unresolved clusters remain separate.
