4. FlashRT: Towards Computationally and Memory Efficient Red-Teaming for Prompt Injection and Knowledge Corruption
- Source: arXiv
- Published: 2026-04-30T17:43:24Z
- Why it matters: Adds a stronger benchmark in agent workflows. Stands out for unusually strong scope and credible evaluation pressure.
- Summary: In this work, we propose FlashRT, the first framework to improve the efficiency (in terms of both computation and memory) for optimization-based prompt injection and knowledge corruption attacks under long-context LLMs. The resource-intensive nature poses a major obstacle for the community (especially academic researchers) to systematically evaluate the security risks of long-context LLMs and assess the effectiveness of defense strategies at scale. FlashRT is best read as a stronger benchmark in agent workflows.
