New research catalogues prompt-injection routes through agent systems as Nadella says models should be treated as compromised
An arXiv study tests injection through both user input and indirect channels in single-agent and multi-agent setups, and Microsoft's chief executive calls for operators to be able to stop a model mid-task.
A paper posted to arXiv today, "An Exploration of Attacks on AI Agent Systems", studies how prompt injection exploits both direct user input and indirect channels in single-agent and multi-agent systems. The abstract argues that agents need…

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.
