Abstract (first 300 chars)

Current LLM safety benchmarks largely rely on binary metrics, overlooking how models respond to harmful prompts with varying threat implicitness. We introduce TIER, a Threat Implicitness Benchmark for behavioral safety evaluation of LLMs. TIER covers four risk domains and four threat levels, from ex…

Suggested OWASP Mapping

LLM01

Suggested Action

Review this paper against the OWASP GenAI Crosswalk entries and update relevant mapping files if new attack patterns or mitigations are identified.

Triage: relevant. LLM safety benchmark over implicit threats: evaluation methodology.

Next step is a content decision: whether it adds an attack pattern, mitigation or evaluation reference to a mapping file. That is expert work (C4), so this stays open.

Triage of the weekly watcher backlog, 2026-09-14. A label and a reason only: no mapping or incident was changed. Reopen or relabel if this reading is wrong.
