Paper Finds Agent Models Internally Encode When Their Tool Output Was Poisoned
The authors report that hidden activations in agentic language models carry a detectable signal of indirect prompt-injection exposure, suggesting a cheap runtime monitor rather than another input filter.
A preprint posted to arXiv, Your Agentic LLMs Secretly Encode Latent Signals of Indirect Prompt-Injection Exposure, takes a different angle on the most persistent security problem in agent deployment. Indirect prompt injection places a mali…
