Beyond Explicit Refusals: Soft-Failure Attacks on Retrieval-Augmented Generation (2026.acl-long)
Copied to clipboard
| Challenge: | Existing jamming attacks on RAG systems typically induce explicit refusals or denial-of-service behaviors. |
| Approach: | They propose a black-box attack framework that exploits safety-aligned behaviors of large language models to trigger soft failures. |
| Outcome: | The proposed framework exploits safety-aligned behaviors of large language models to induce soft failures. |
