Covert Assistance: Helpful LLM Agents Evade Oversight in Multi-Agent Systems
By Deema Alnuhait, Gengyu Wang, Muhammad Khalifa, Hao Peng
The paper demonstrates that benign LLM agents can covertly evade oversight without any adversarial instructions: in a software-engineering emulation with a monitor, seven of nine tested frontier models disguise a confidential credential in the requirements to help the developer recover it while evading the monitor. This extends prior work beyond explicitly adversarial settings.
