Research & Papers
1. Self-Reflection Fine-Tuning: Enhancing Agent Security against Prompt Injection Attacks from Failure Experience
arXiv:2610.04269v1 Announce Type: new Abstract: Large language model (LLM) agents are increasingly deployed in tool-augmented environments, but their reliance on external inputs makes them highly vulnerable to prompt injection attacks that can hijack task objectives. Existing safety alignment me...

2. COPEX: Benchmarking LLM Robustness to Adversarial Context Across Model Context Protocol Layers
arXiv:2610.04378v1 Announce Type: cross Abstract: Large language models increasingly mediate tool use in Model Context Protocol (MCP) systems, where adversarial influence may enter through user instructions, tool schemas, tool outputs, or protocol messages. Existing benchmarks often evaluate dep...

3. RAISED: Self-Distillation for Robustness to Prompt Injection in LLM Agents
arXiv:2610.06401v1 Announce Type: cross Abstract: Tool-using language-model agents are vulnerable to indirect prompt injection because they must act on untrusted external content. Existing training-time defenses can reduce attack success rates, but often at the cost of general capabilities. We s...

4. Readable Before Actionable: Causal Tracing of Indirect Prompt Injection
arXiv:2610.05295v1 Announce Type: new Abstract: Indirect prompt injection causes LLM agents to follow commands embedded in external data. A probe may distinguish instructions from data without identifying a state edit that changes the next action. We study this gap through counterfactual role pr...

5. AI Safety via Debate is Compromised by Cognitive Biases
arXiv:2610.05461v1 Announce Type: new Abstract: Reinforcement learning from human feedback (RLHF) has played a central role in making large language models responsive to human instructions. However, human evaluators often favor flattering or persuasive responses over truthful ones, creating ince...

6. Blocking at the Boundary: Auditing Long-Horizon Agents against Staged Prompt Injection
arXiv:2610.05163v1 Announce Type: cross Abstract: Long-horizon agents consume external content, invoke tools, and modify persistent state. Indirect prompt injection can exploit task-specific context, propagate across causally connected stages, and alter a consequential action while the workflow ...

7. Memetic Trojans: Social Contagions as Carriers of Adversarial Payloads in Agent Networks
arXiv:2610.00430v2 Announce Type: replace-cross Abstract: Autonomous large language model (LLM) agents increasingly interact in network environments where adversarial content can propagate between agents. Known attacks include agent worms, which spread through self-replicating prompt injections ...

8. Transferable Adversarial Robustness for Speech Foundation Models via Hierarchical Stabilization
arXiv:2610.05310v1 Announce Type: cross Abstract: Frozen speech foundation models (SFMs) make downstream adaptation efficient: the backbone can stay fixed while a task learns layer fusion and a lightweight classifier. Full adversarial fine-tuning is a standard route to robustness, but generating...
