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.

Moonbounce converts content moderation policy documents into executable, runtime-enforced logic — bridging the gap between what a platform says it prohibits and what it actually enforces in real time. Founded by Brett Levenson, former Business Integrity lead at Facebook/Meta, it launched out of stealth with a $12M seed round co-led by Amplify Partners and StepStone Group. The "policy as code" approach means moderation rules written in natural language get compiled into deterministic enforcement logic that responds in under 300 milliseconds. This matters for AI platforms where generative content flows too fast for traditional human-in-the-loop review. Current customers include AI companion apps (Channel AI, Dippy AI, Moescape) and image generation platforms (Civitai), which are the sectors currently operating in the most contested content gray zones. The broader context is that as AI-generated content scales, the enforcement gap between stated policy and actual behavior becomes a legal and reputational liability. Moonbounce is betting that every platform deploying a generative AI product will eventually need a compliance layer — and that being "policy as code" rather than "rules as vibes" is the defensible position.
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.”
“Sub-300ms enforcement at the API layer means I can ship generative features without building a custom moderation pipeline from scratch. The policy-as-code abstraction is the right mental model — if I can read and audit the compiled enforcement logic, I can trust it more than a black-box classifier.”
“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.”
“Policy documents are inherently ambiguous, and compiling ambiguity into deterministic enforcement creates false confidence. Edge cases will still need human review, and the question is whether you're adding a compliance theater layer or actually reducing harm. The AI companion customer base also raises questions about who's using this and for what.”
“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.”
“Trust and safety infrastructure for AI-generated content is a fundamentally unsolved problem at scale. Moonbounce is approaching it as a developer infrastructure play rather than a compliance consulting play, which is the right bet — platforms need APIs, not auditors.”
“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.”
“Platforms like Civitai hosting AI-generated imagery have faced real harm without adequate enforcement tools. A system that lets platforms encode their actual values into runtime behavior — rather than aspirational policy pages — is meaningful for building creator communities that aren't destroyed by misuse.”
