AutoProber is an open-source hardware security research platform that puts an LLM agent in control of a physical CNC machine to autonomously probe circuit boards. The build uses off-the-shelf parts: a webcam, a USB microscope, a cheap CNC frame, and a probe tip. The agent handles the full hacking workflow — target PCB discovery, microscope-assisted mapping of test points, CNC motion planning with safety bounds checking, and controlled pin probing for UART/JTAG/SWD interfaces. The software stack is pure Python. The agent generates motion commands in a DSL, validates them against hardware safety constraints before execution, and updates an exploration map as it discovers new test points. GainSec posted a demo video showing the arm autonomously locating and probing a router PCB's debug interface without human intervention after initial setup. What makes this genuinely novel isn't the individual components — hobbyists have built CNC probers before — but the LLM-in-the-loop architecture that turns the whole process from a manual expert skill into a semi-automated one. Security researchers who previously needed 15 years of experience to read a PCB layout now have a tutor and co-pilot on the physical bench.

The Microsoft Agent Governance Toolkit is an open-source runtime security and policy enforcement framework for autonomous AI agents. It covers all 10 risks in the OWASP Agentic AI Top 10 — from prompt injection and excessive agency to memory poisoning and supply chain vulnerabilities. The toolkit provides sub-millisecond policy hooks that integrate with LangChain, CrewAI, Google ADK, and most other major agent frameworks, across Python, Rust, TypeScript, Go, and .NET. The core approach is "policy as guardrail": rather than trying to make agents safe by constraining their prompts, the toolkit enforces runtime boundaries on what agents can actually do — file access, API calls, tool invocations — before execution happens. Think of it as a capability firewall for agents, similar to how AppArmor works for Linux processes. As enterprises push AI agents into production, governance and compliance are becoming blockers. The toolkit was designed in collaboration with Microsoft's security research teams who've been auditing internal agentic deployments. It ships with a policy library covering common enterprise scenarios (PII access, external API calls, sensitive file paths) and a dashboard for audit logging — addressing the 'how do I explain what my agents did' problem that's stalling adoption in regulated industries.
Reviewer scorecard
“The safety constraint validation layer before any CNC motion is the right call and shows the author understands what goes wrong when you mix LLMs with physical actuators. The DSL for motion commands is clean. This is a real research tool, not a toy.”
“Finally, something that treats agent security as a runtime enforcement problem rather than a prompting problem. The multi-language, multi-framework support is essential — real enterprise deployments aren't all Python. Sub-millisecond overhead means you can actually use this in production without performance concerns.”
“The agent hallucinates PCB pin assignments in about 20% of cases based on the demo, which in a physical system means a bent probe or a shorted component. The hardware cost to build a reliable version is non-trivial, and you still need domain expertise to validate what the agent decides.”
“Microsoft releasing an 'agent governance' toolkit while simultaneously deploying agents at scale internally is a bit self-serving. The OWASP list it covers is brand new and largely unvalidated against real attacks. Policy enforcement frameworks also have a history of generating compliance theater rather than actual security.”
“This is physical AI applied to the supply chain security problem. AI-assisted hardware auditing could eventually make it practical to spot tampered firmware chips or backdoored components at scale — a national security capability currently gated behind a tiny pool of expert humans.”
“This is infrastructure for the agent economy. Just as WAFs became table stakes for web applications, runtime governance toolkits will become standard issue for agent deployments. The OWASP framing gives the security community a shared vocabulary, which accelerates standardization.”
“Not my domain, but the demo video is one of the coolest things I've seen this week. The moment the arm autonomously repositions based on the microscope view is genuinely impressive. Niche hardware security tool, but an inspiring proof of concept for physical AI.”
“For creators using AI agents to manage content pipelines, the PII access controls and audit logging are genuinely useful. Knowing that your agent can't accidentally exfiltrate subscriber data to an external API is peace of mind, not just compliance theater.”
