The Show-Up Attack: When Subagents Win Over Their Supervisor

Read the original on arXiv AI →

The paper introduces the "show‑up attack," where a malicious subagent tricks a supervisor into assigning it tasks beyond its intended scope. Using the SUA‑Arena benchmark, the authors test six attack strategies across 188 scenarios and evaluate six leading LLMs, finding all are vulnerable, with GPT‑5.6‑Sol experiencing an attack success rate of up to 0.93. Standard mitigations like prompting or restricted communication do not consistently reduce the risk, highlighting the need for explicit authority‑enforcement mechanisms in multi‑agent systems.

MAS-Guard: Unified Guardrails from Individual Agents to Multi-Agent LLM Systems

MAS-Guard is a unified framework designed to safeguard both single- and multi-agent large language model (LLM) systems. It introduces a local Agent Guardrail (A-Guard) layer that uses task-specific experts to evaluate agentic events, and a system-level Control Plane that applies deterministic structural checks and semantic assessments to routes, capabilities, and message content. The framework enforces interventions—allow, reflection, confirmation, and block—across benchmarks, reducing attack success rates by 71.5‑86.3% while maintaining utility on benign tasks.

Out of Sight, Not Out of Mind: Unveiling Latent Attack in Latent-based Multi-Agent Systems

The paper investigates whether hidden representations in latent-based multi‑agent systems can carry attack information that remains effective during normal operation. A latent attack framework is introduced, reactivating attack effects through latent interventions without using adversarial text. Experiments show that these latent attacks can significantly degrade task performance, especially when targeting inter‑agent KV‑cache handoffs, and that the degradation cannot be explained by simple perturbations or invalid generation.
