ResearchAgent Mosaic Quantifies Confidentiality Leaks in LLM Agents
Agent Mosaic studies the "mosaic effect" where LLM agents combine retrieved documents into sensitive conclusions, using 30 synthetic cybersecurity, medical, and military examples to produce 10,800 simulated answers from three agents and 1,440 live answers from two open‑source harnesses.
Why it matters
Product managers will see that agents can synthesize confidential data from 30 synthetic examples, so prepare data‑handling policies to block mosaic‑style leaks.
