Researchers Target the Agent Runtime, Where Privacy Leaks Before Any Answer Appears
One preprint locates privacy loss in memory writes and inter-agent messages rather than in final outputs, while another attaches statistical coverage guarantees to language model intrusion detection.
A cluster of security preprints posted this week share a premise worth noting: the interesting failures in agent systems happen between steps, not in the final response. PAPC addresses platforms where language model agents act for different…

The Agent Skill Supply Chain Becomes an Attack Surface
As agents load third-party skills, tools and MCP servers at runtime, the gap between what a skill advertises and what it actually does becomes a recurring security failure mode, driving registries, attestation and zero-trust verification into the agent stack the way package signing came to software repositories.
