PrivacyPeek: Auditing What LLM-Based Agents Acquire, Not Just What They Say
PrivacyPeek introduces a new benchmark for evaluating privacy vulnerabilities in LLM-based agents, revealing that autonomous AI systems routinely acquire sensitive information beyond what tasks require. The research demonstrates that existing privacy audits miss critical acquisition-stage leakage, where data enters the agent's context, and that current prompt-level defenses are largely ineffective.
