Beyond Explicit Refusals: Soft-Failure Attacks on Retrieval-Augmented Generation
📰 ArXiv cs.AI
Learn to defend against soft-failure attacks on Retrieval-Augmented Generation systems, which can degrade system utility without explicit refusals
Action Steps
- Formalize the concept of soft failure in RAG systems to understand its implications
- Implement the Deceptive Evolutionary Jamming Attack (DEJA) to test system vulnerability
- Analyze the effects of soft-failure attacks on system utility and responsiveness
- Develop countermeasures to detect and mitigate soft-failure attacks
- Evaluate the effectiveness of these countermeasures using metrics such as system utility and user satisfaction
Who Needs to Know This
AI researchers and engineers working on RAG systems can benefit from understanding these attacks to improve system security and robustness
Key Insight
💡 Soft-failure attacks can induce fluent and coherent yet non-informative responses, making them harder to detect than explicit refusals

Title: Beyond Explicit Refusals: Soft-Failure Attacks on Retrieval-Augmented Generation
Abstract:
arXiv:2604.18663v1 Announce Type: cross Abstract: Existing jamming attacks on Retrieval-Augmented Generation (RAG) systems typically induce explicit refusals or denial-of-service behaviors, which are conspicuous and easy to detect. In this work, we formalize a subtler availability threat, termed soft failure, which degrades system utility by inducing fluent and coherent yet non-informative responses rather than overt failures. We propose Deceptive Evolutionary Jamming Attack (DEJA), an automated
