• Third-party-reported, not independently verified by Chollima Hunter. The report marks two of these as novel to the incident it describes and the rest as already shared with PolinRider infrastructure, which is why most were already held here from other reporting; carrying them again records the corroboration rather than adding new claims. These are the attacker-side entries from the report's indicator table only. The 27 compromised packages and Go modules it also lists are the projects that were attacked, and naming those as indicators would name the victims.
