The week AI-written exploit code entered a federal advisory, and no frontier lab could show a containment plan

Guidelight AI Standards published a comparative assessment of how five frontier labs control their own AI systems(opens in a new tab), current through August 18. Anthropic and OpenAI tied at the top with a C+, scoring 2.50 out of 5. Google took a D+ at 1.50, xAI a D- at 0.83, and Meta an F at 0.67. The six practices scored were logging, monitor efficacy, gated actions, circuit breaking, third-party review, and having a containment plan at all. No company scored above a 3 on any single practice, and most scores were a 2 or lower.

The methodology caveat matters more than the letter grades. Guidelight scored only what is public, so a low grade can mean weak controls or simply no disclosure. For a buyer that distinction is academic. Third-party risk management is a documentation exercise, and as TechCrunch reported on Saturday(opens in a new tab), the documents describing containment response and independent audit of controls mostly do not exist. A questionnaire sent into that vacuum measures a vendor's willingness to write things down, not the state of its controls.

On August 19 the NSA, CISA, FBI, Department of Energy, and EPA released advisory AA26-231A(opens in a new tab) on an active threat to Siemens S7 Series programmable logic controllers. Threat actors are building AI-generated Python scripts on the public snap7 library, disguising them as operational technology monitoring tools, and using them for read and write access to PLC memory, configuration data, and ladder logic over S7comm. The sectors named are Critical Manufacturing, Energy, Water and Wastewater, Chemical, Food and Agriculture, and Commercial Facilities. The agencies write that using AI this way "represents an evolution in threat actor capabilities, dramatically reducing the technical expertise and time required to develop working ICS exploitation scripts."

That sentence belongs in front of a risk committee. The scarce input in an attack on industrial control systems used to be a person who understood both the S7comm protocol and offensive tooling. The advisory says that constraint is loosening. Nothing about the plant changed. The number of people who can reach it did, and the agencies call the activity persistent reconnaissance and capability development, meaning positioning for later write operations rather than damage today.

The third item this week shows the same pressure applied to a control the enterprise already bought. Adversa AI's technique against Grok puts encrypted instructions and their key on a web page. Scanners see ciphertext and pass it through, and the assistant's own code sandbox decrypts the payload and treats it as trusted context, appending the user's name, coarse location, subscription tier, and full prompt history to an attacker's URL. Every content inspection control at the boundary assumes a readable payload. That assumption is now optional for the attacker, which moves the defensible line from what an agent is allowed to read to what an agent is allowed to do.

Three asks, in the order they are worth your time.

Send the six Guidelight practices to every frontier model vendor under contract and ask for each one in writing, with the containment plan and the third-party audit question first. The useful answer is not a yes. It is whether anyone at the vendor can name the plan, its trigger, and who is allowed to invoke it. A refusal to answer is a scoring input, not a dead end, and it is cheaper to collect now than during renewal.

Ask whether anyone in the AI program has spoken to the operational technology side of the business this year. The advisory's first mitigation is an inventory of Siemens S7 PLCs, which is a plant engineering task, not an AI task. The AI angle is what puts it on your desk: five agencies signed a document describing AI-generated attack code as an active threat rather than a forecast, and the CISO will circulate it under that heading. Being the person who already knows whether those devices are internet-exposed is worth more than another governance slide.

For anything agentic in production or in pilot, stop budgeting for payload inspection alone and start budgeting for permissions. Egress allowlists, tool scoping, and a rule against executing code derived from fetched content are all cheaper than a filter that has to read what an attacker chose to encrypt. Ask each agent vendor one question before signing: can the product run code on content it retrieved from a page it did not vet?
