New Papers Map How Much Private Data Agents Leak Through Ordinary Tool Calls
A measurement on three production agent stacks finds models routinely put sensitive data into tool arguments that the tool never needed, and a companion survey catalogues attacks on retrieval pipelines.
Two papers posted to arXiv this morning address the same weakness from opposite ends: what agents send out, and what they take in. The first, ToolMinimize, measures privacy-sensitive data in tool call arguments across three production-grade…

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.
