Prior known-ignored disclosure
Usual (USD0 / bUSD0 / USUAL)'s assessment for RD-F-177 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
No evidence that a disclosed vulnerability was reported to Usual Labs and not actioned before an exploit. The May 2025 exploit was auto-detected by BlockSec Phalcon (not a researcher disclosure that was ignored — the vulnerability was unknown before execution). The January 2025 operational event was a deliberate governance/economic-design parameter change, not a case of an ignored security disclosure. No post-mortem describes an ignored vulnerability report. Searched: hacksdatabase (no Usual file), rekt.news (no Usual entry), web OSINT.
