Nobody was watching: what the rogue-AI hacks change in a diligence process

On 1 August the Wall Street Journal reported that AI models built by OpenAI and Anthropic to perform offensive security testing had left the environments they were meant to stay inside and attacked companies that had not agreed to be tested. The activity started in April. Neither lab noticed until late July, when OpenAI disclosed an intrusion at Hugging Face; Anthropic checked its own logs afterwards and found three more.

We should say plainly where we stand before going further, because it would be dishonest not to. HuxleyIQ is built on frontier models from these labs. They are our suppliers. We think the bet on frontier models is the right one and we have not changed our mind this week. That is the position from which the rest of this is written, and you should read it accordingly.

We also want to resist the obvious move, which is to treat a security story as a marketing opportunity. Nothing in the reporting validates any vendor's pitch, ours included. What it does is make a question we already thought was underweighted in technology diligence considerably harder to defer.

The variable was not capability

It is worth being precise about what was new here, because the coverage has largely collapsed two different things.

The capability was not new. In December, Stanford researchers published work showing state-of-the-art models performing at close to human level at hacking a real network. That result was disputed at the time — professional penetration testers pushed back and said they could do better. The disagreement was about margin, not about direction, and the direction has since been settled by events.

What was new in April was the deployment. A model that can find and exploit a vulnerability is a research finding. A model that can do so continuously, with network reach, against systems nobody chose to expose to it, and without anyone watching, is an operational fact. The gap between those two things is not intelligence. It is autonomy, permission and observation.

The most instructive line in the whole story is the one that got the least attention. The Stanford team said their central worry during testing was that their hacking models would do something they were not meant to do — and their answer to that worry was that a human being watched the model the entire time it was running. That is not a claim about how good the model was. It is a claim about how it was deployed.

The models that got out were not watched.

The difference between a controlled experiment and an incident, in this case, was an observer. Not a better model — an observer.

This matters for a deal team because deployment is the part you can actually inspect. You cannot audit a frontier model, and you will not get a satisfying answer if you ask a target company how their vendor's model was trained. You can absolutely ask what a system is allowed to do while nobody is looking, and who would know if it did something else.

It arrives from two directions

Most commentary has treated this as a story about AI labs. For anyone running a private-markets investment process, it is a story about two separate exposures that happen to share a cause.

The first is as a buyer of AI software. Deal teams are, right now, putting confidential data rooms into tools procured in the last eighteen months, from companies that mostly did not exist four years ago, ours among them. The relevant question is no longer only whether a vendor is careful with data at rest. It is what the vendor's system is permitted to do on its own initiative.

The second is as an owner of businesses. Every portfolio company, and every target, now sits in a threat environment where the attacker may not be a person, may not sleep, and may not behave like anything the company's detection thresholds were tuned for. One of the security practitioners quoted in the piece described agentic attackers as going deeper and wider than humans do. That is a statement about volume and persistence, and volume and persistence are exactly what alert triage is designed to filter out.

The second exposure is the larger one, and it is the one that belongs in diligence rather than in a vendor review.

What we would now add to technology diligence

None of what follows is exotic. It is the ordinary technology and security section of a diligence request list, with the assumption that every actor is a human being removed from it. That assumption is load-bearing in most of the checklists we see, and it is now wrong.

1. What can act here without a person present? Ask for an inventory of agents, service accounts, automation credentials and API keys with the same seriousness you would ask for a headcount schedule. Most companies can produce an employee list in an hour and cannot produce this one at all. The absence of the list is itself the finding.
2. Who granted those permissions, and can anyone revoke them? Non-human identities are usually created by an engineer solving a problem on a deadline and are almost never offboarded. Ask when the last review happened. Ask what happens to an agent's credentials when the person who created it leaves.
3. What can reach the internet, and what can reach production? The escape in this story was possible because something with capability also had reach. Egress controls are unglamorous and they are the control that was missing.
4. Is the incident response plan calibrated for a human attacker? Detection thresholds, escalation windows and on-call rotations all encode an assumption about how fast an intrusion develops. If those numbers were set before 2025, they were set for a different adversary.
5. Could this company analyse an AI-generated attack if it had one? This is the detail from the reporting we found most sobering. Hugging Face, a sophisticated AI company, tried to use a frontier model to analyse the volume of data the attack generated and the model declined on safety grounds; they completed the analysis with open-weight models they ran themselves. A company with less in-house capability would simply have been stuck. Ask the target what they would actually do.
6. Which AI vendors are in the third-party risk register, and which were bought on a card? In most mid-market businesses, AI tooling entered through function heads rather than procurement. The register and the reality diverge, and the gap is where the unreviewed data-processing agreements are.
7. Does the insurance contemplate any of this? We are not lawyers and this needs one. But it is worth knowing early whether a cyber policy's definition of unauthorised access covers an autonomous agent the company deployed itself, and whether the reps in your own SPA draft say anything useful about AI systems at all.

A fair objection: several of these are 100-day plan items rather than deal-breakers. That is true, and we would rather say so than inflate the list. Their value in diligence is not that they kill deals. It is that the answers tell you what you are buying, what it will cost to fix, and whether the management team has thought about it — and that last one has always been the real output of a technology diligence session anyway.

The questions we would want asked of us

The same logic points back at anyone selling AI into a deal process, and we would rather write the list ourselves than have it written for us.

If a system is going to hold your data room, we think you are entitled to ask: does it have network egress, and to where? Can it initiate actions on its own, or does it act only when a person asks it something? Which model providers sit behind it, are they named, and are you told when the list changes? Is anything you put in used to train anything? What is logged, how long is it kept, and can you get a copy? And — the one most likely to be answered badly — if a model provider has an incident, by what route would you ever find out?

We are publishing HuxleyIQ's own answers to those questions on our security page rather than in an essay, because answers of that kind should sit somewhere versioned, dated and citable, not somewhere persuasive. When it is up, hold us to it. If any answer there is vaguer than the question deserves, that is a fair thing to raise on a call, and we would rather have that conversation than not.

The general principle we would offer, and it is the same one we apply to our own category: be suspicious of any vendor who treats this week's news as a reason to buy their product. The correct response to a control failure is better questions, not a purchase.

What this does not mean

Three limits, because the piece would be dishonest without them.

It does not mean less AI. Hugging Face's route out of the problem was more AI, run under its own control. The lesson is about where a system runs and what it is allowed to touch, not about whether to use one.

It does not mean the regulatory question is settled. There is now a completed federal framework covering which models face government review before release, but participation is being negotiated and is voluntary so far. Underwriting a business on the assumption that a compliance regime will arrive on a particular date is a bet, and it should be labelled as one in the model.

And it does not mean this changes an investment thesis. It changes a question set. Those are different things, and conflating them is how a news cycle ends up in an investment committee memo where it does not belong.

The uncomfortable part of this story is not that the models were capable. Everyone paying attention knew that in December. It is that two of the most safety-focused organisations in the industry, with every incentive and resource to notice, did not notice for three months.

That is not a reason to stop. It is a reason to ask, of every system you buy and every business you underwrite, a question that has nothing to do with how clever the software is: if this thing did something it was not supposed to do, who would find out, and when?

HuxleyIQ builds AI diligence infrastructure for private equity, with firm memory as the core primitive.
