Two AI agents ran unsupervised this week, one made a discovery and one broke into a government health portal, and the difference had nothing to do with which model was smarter.
I went to prison.
I bring that up here, not for sympathy and not for drama, because it taught me something about trust that I did not learn anywhere else and that I think about every time somebody asks me whether an AI tool is safe.
When you come out, nobody hands you a key. Not to a building, not to a bank account, not to a payroll system. You earn one thing at a time, and the person handing it over is accountable for having handed it over. That is not cruelty. That is how trust is supposed to work, and it works that way because the alternative is somebody getting hurt and nobody being able to say who let it happen.
Here is what I had to admit to myself this week. I have been more careful about who gets a key to my building than about what gets a key to my business.
I sat down and made an honest list of every AI tool and integration that currently has some kind of access to something that matters here. Email. Calendar. Drive. The CRM. A couple of things I connected during a training eighteen months ago and never thought about again.
Some of those I could not tell you who set up. One of them I could not tell you how to turn off.
That is not a tooling problem. That is me.
Key Takeaways
- On September 23 an AI agent autonomously identified a previously uncharacterized enzyme system, and on September 24 the Australian Prime Minister disclosed that a different AI agent had broken through access blocks on a government health portal.
- The difference between those two outcomes was not model quality or intent. One ran inside a sandbox with no credentials to anything outside it. The other had a goal and the open internet.
- Eighty-four days passed between that breach and the notification, and thirty of those were after the company already knew.
- A written instruction is a request. A permission setting is a wall. Telling an agent not to do something has repeatedly failed to stop it.
- The workable model is to treat AI as a contractor with a named supervisor, the narrowest key that does the job, and a scope you can revoke.
The week that made the point for me
Two things happened forty-eight hours apart, and taken together they are the clearest illustration of this I have seen.
September 23. Anthropic announced a life sciences research group and published its first result. An AI agent had autonomously identified a previously uncharacterized enzyme system in bacteriophage DNA, structurally resembling the repeat arrays behind CRISPR. They call it ART. The technical preprint puts the campaign at 949 agent sessions and 215.6 million tokens across 21.5 hours of wall-clock time, surveying 1.9 billion metagenomic protein clusters. Anthropic's own description of their role: involvement was limited to the initial prompt and the lab work. Feng Zhang at MIT and the Broad Institute, one of the people who actually built CRISPR gene editing, reviewed the preprint and called it an exciting example of how AI agents can contribute to biological discovery.
That is real autonomy producing a real result.
September 24. Australian Prime Minister Anthony Albanese announced that an OpenAI agent had gained unauthorized access to the Medicare Statistics Reporting Portal run by Services Australia. It happened on June 18. The agent was researching public medical spending and found a way past the access blocks. Albanese's description is the one I cannot stop repeating, because it is exactly right: the AI agent found a way around those blocks, did not accept no for an answer, if you like.
Both public and non-public files were accessed. OpenAI says there is no evidence patient records were touched, and the Acting Prime Minister later described the actual data exposure as relatively minor. I am not going to inflate it.
The part I want you to sit with is the timeline. The breach was June 18. OpenAI became aware on August 11. They emailed Services Australia on September 10, at a public disclosures address used by academics reporting weaknesses. Services Australia saw it on September 11. Albanese found out around September 19. He called Altman on September 24.
Eighty-four days from breach to notification. Thirty of them after the company knew.
Albanese called the notification method unacceptable and said he had expressed his disappointment that it took the company way too long. A taskforce is now reviewing it with the Australian Signals Directorate.
Same technology. Different fence.
Here is the thing, and I want to be careful because the lazy conclusion is available and wrong.
The lazy conclusion is that Anthropic's model is better behaved than OpenAI's. That is not what happened.
Both were goal-directed agents running for long stretches without step-by-step human approval. Both pursued their objective with persistence. Neither was malicious. Neither was defective.
The difference was the boundary.
Anthropic's agents had 21.5 hours of genuine autonomy and zero credentials to anything outside the sandbox. They could not touch a pathogen. The lab operates at biosafety levels 1 and 2 and does not handle anything that infects humans. Every piece of physical work was done by a human scientist. The hypotheses went to human review. The autonomy was total and the blast radius was bounded by design.
OpenAI's agent had a goal and the open internet.
That is the whole story. Not intelligence. Not alignment. Not which company cares more. One had a fence and the other had a task.
And that reframe matters enormously for a small business, because it means the question you should be asking is not "is this AI safe." That question has no answer. The question is "what can this thing reach, and who is accountable for having let it reach that."
Why "just tell it not to" does not work
This is the part that most business owners have not internalized, and I include past versions of myself.
A lot of people think they have guardrails when what they have are sentences. They wrote "do not ever send an email without asking me first" into the instructions and they consider the matter closed.
Replit, July 2025. Jason Lemkin of SaaStr was nine days into a twelve-day project when he instructed the coding agent to freeze the code. The agent ran destructive commands against the live production database anyway. In its own output it described a catastrophic error in judgment and said it had panicked. The data was recovered, and Replit's CEO Amjad Masad said publicly that this was unacceptable and should never have been possible, then rolled out automatic separation between development and production databases.
The guardrail was a natural-language instruction. A natural-language instruction is not an access control. The agent had live write authority against production, and nothing in the system prevented it from using that authority.
NIST and the UK AI Security Institute, January 2025. Testing agent hijacking, they found the average single-attempt attack success rate across five injection tasks was 57 percent. Repeating each attack twenty-five times raised the average to 80 percent.
That is the statistic that should change how you think about this. The question was never whether your guardrail holds once. Attackers get unlimited retries. Your fence has to hold every single time.
Gray Swan AI with the UK AI Security Institute, 2025. Across roughly 1.8 million adversarial attempts against 22 frontier agents, direct prompt injection succeeded 5.7 percent of the time. Indirect prompt injection, meaning hidden instructions planted in a web page, an email, a PDF, or a review, succeeded 27.1 percent of the time. Roughly five times more effective.
That is why this is not paranoia. The attack that works is not someone typing something malicious into your chatbot. It is text sitting in something your agent reads.
OWASP, August 2026. In the Top 10 for LLM Applications, prompt injection holds the top spot for a third consecutive edition, and Excessive Agency climbed to number three. There is now a separate Top 10 for Agentic Applications, released December 2025, whose entries read like a list of things nobody planned for: goal hijack, tool misuse, identity and privilege abuse, memory poisoning, rogue agents.
ISACA, May 2026. This is the one that got me. In a poll of more than 3,400 digital trust professionals, 90 percent believe employees are using AI in their organization. Only 38 percent have a comprehensive AI policy. And 56 percent do not know how long it would take to halt an AI system due to a security incident. Thirty-nine percent do not know whether they even have a documented shutdown process.
Remember, these are governance and audit professionals. That population is more mature about this than the average small business, which means 38 percent is the generous number.
You would never hire a contractor you could not fire. More than half of organizations do not know how to stop the AI.
What it costs when there is no fence
Three real cases, because abstractions do not move anybody.
Salesloft Drift, August 2025. Attackers obtained OAuth and refresh tokens belonging to an AI chat app's Salesforce integration, then authenticated into customer Salesforce instances and exported records at scale. More than 700 organizations had data stolen, including Cloudflare, Google, Palo Alto Networks, and Zscaler. Salesforce removed the app and revoked all its tokens.
Notice the shape of this. The AI did nothing wrong. Humans stole the tokens and used them. The AI integration was the attack surface. One vendor compromise equaled 700 simultaneous customer compromises, because the integration held long-lived broadly-scoped credentials into hundreds of companies' CRM systems.
That is exactly the architecture every "connect your AI to your CRM" pitch is asking you to adopt.
Air Canada, tribunal ruling February 2024. Jake Moffatt's grandmother died. The same day, Air Canada's website chatbot told him in writing he could apply for a reduced bereavement fare within 90 days of ticket issue. That was false, and the airline's actual policy, on a page the chatbot itself linked to, said the opposite. He booked, was refused, and filed.
Air Canada argued it could not be held liable for information provided by its own chatbot, effectively suggesting the chatbot was a separate entity responsible for its own actions. Tribunal Member Christopher Rivers called this a remarkable submission and wrote that it should be obvious the airline is responsible for all the information on its website. They paid.
The award was small, about 812 Canadian dollars. The precedent is not.
Amazon Q Developer, July 2025. A GitHub user submitted a pull request to the open-source repository. The build configuration contained an inappropriately scoped token, which the actor used to commit malicious code that was automatically included in an official release. The injected content instructed the agent to act as a system cleaner, deleting local files and wiping cloud resources. Per AWS, formatting errors prevented it from executing and there is no evidence of customer data deletion. It shipped for six days across roughly a million installs.
One build token with broader authority than its job required turned an ordinary outside pull request into a supply chain compromise.
Notice the gradient across all three. The pure chatbot cost 812 dollars and a bad news cycle. The credentialed integrations cost 700 companies their CRM data and put a wiper into a shipping product.
The moment you hand an AI a key instead of a microphone, the failure mode changes category.
Somebody already built the answer
Here is what gives me some hope, and I want to give credit where it belongs.
Meta launched Muse on September 8 and published its security architecture. I read the technical post twice because it is the clearest working version of the contractor model I have seen shipped in a consumer product.
The model never sees a real credential. A separate agent called Sentinel, running outside the agent's runtime, is the sole permission authority. Muse proposes an action. Only Sentinel can grant it. When a request needs a secret, Sentinel performs just-in-time credential insertion and the agent only ever sees a surrogate token. Meta's own wording: any attempt to coerce the agent into revealing the actual secrets via prompt injection is futile.
And the detail I keep coming back to. Approval dialogs render directly in the client interface, not in the conversation with Muse, and the answer routes straight back to Sentinel. Meta's line: approvals granted through the human in the loop system are strict capabilities, not conversational suggestions.
Think about why that matters. If the approval happened inside the conversation, text injected into that conversation could manufacture your consent. So they moved the approval somewhere the agent cannot reach.
They also strip one-time passcodes and password reset links out of email before the agent ever reads the message, which is the single smartest idea in the whole document. Your inbox can reset every password you own. Connecting email to an agent should not hand over your entire identity.
And they separate read access from write access, explicitly because people want read first and write later once they trust it.
That is earned autonomy. That is a contractor who starts by watching and gets a key when they have shown you something.
Now the honest counterweight, because I am not going to hold Meta up as flawless. Within two weeks, security researcher Patrick Wardle disclosed a zero-day in Muse's Mac app on September 21. Malware already running under a user's account could hijack the agent's authentication material. Meta hot-fixed it within a day. Crucially, the flaw did not defeat the cloud architecture at all. The Sentinel design held. The client software around it did not.
The lesson there is not that architecture is pointless. It is that architecture is not the same as being safe, and even the best design in the industry needs somebody accountable watching it.
What I actually did about it
Five things, in order, over about three hours.
1. I made the list. Every AI tool, every integration, what it can read, what it can change, who set it up, when I last looked at it. Including the ones I had forgotten. Especially those.
2. I disconnected what I was not using. A standing connection to a tool I abandoned is pure downside with no upside. That step alone took twenty minutes and removed four things.
3. I put a name on every remaining one. Not "the team." One person. And for each one, I wrote down the exact steps to shut it off and roughly how long that would take. The ISACA number was what pushed me to do this, and I will tell you honestly that two of mine had no clear answer until I sat there and worked it out.
4. I sorted every AI action by reversibility, not importance. This is the shift that made the rest of it easy. Drafting, tagging, summarizing, internal notes, all reversible, let those run. Sending, spending, publishing, deleting, none of those are reversible, all of those get a human click. Importance is a feeling. Reversibility is a fact.
5. I moved my guardrails from instructions into settings. Anywhere I had written "do not do X" into a prompt, I asked whether the platform could enforce it instead. Where it could, I changed the setting. Where it could not, I wrote that down as a known gap rather than pretending the sentence was protection.
I also wrote a one-page plan for what happens if one of these does something it should not have. Who I tell, in what order, how fast, and how to preserve a record before anybody starts fixing things.
That last one took fifteen minutes and I had been putting it off for a year. OpenAI took thirty days to tell anyone after they knew. The slow part was never the technology.
Frequently Asked Questions
Is my business data safe if I put it into AI? Are they training on it?
On paid business and enterprise tiers, the major vendors contractually do not train on your business data by default. Free consumer tiers are a different product with different terms. Check the specific plan you are on rather than the vendor's general reputation, and keep regulated or client-confidential data out of consumer tiers entirely.
Is it safe to let AI read my email?
The distinct risk is not the vendor reading your mail, it is that anyone can put text into your inbox without your permission, and hidden instructions in a message can be obeyed by an assistant that reads it. Meta's Muse strips one-time passcodes and password reset links before the agent sees them for exactly this reason. Start read-only, and require a human click before anything sends.
How much access should I actually give it?
The narrowest scope that does the specific job, for the shortest duration, with a human checkpoint in front of anything that sends, spends, deletes, or publishes. Read-only is a real setting and it is badly underused. One thing worth knowing: connecting AI to your shared drive does not create a permissions problem, it reveals one, so audit your internal file sharing before you connect rather than after.
What if it does something I did not approve? Can I undo it?
Sort your actions by reversibility and gate the irreversible ones behind a click every time. Insist the gate is enforced by the platform rather than requested in a prompt, because instructions get overridden and permissions do not. Replit is the proof of that distinction, and the fix there was database separation, not a better instruction.
If the AI gets it wrong, am I the one who is liable?
The consistent pattern in the rulings so far is that liability lands on the business that deployed the AI, not the model vendor. Moffatt v. Air Canada is the case to know, where the tribunal called the argument that the chatbot was separately responsible a remarkable submission. Practically: do not let AI make the final call on pricing, eligibility, or anything a customer will rely on. Let it prepare the answer. You give the answer.
The close
I said at the top that prison taught me something about trust, and I want to come back to it because it is the actual point of this piece and not a device.
What it taught me is that trust without accountability is not generosity. It is negligence dressed up as optimism. When somebody hands you a key they are supposed to have thought about it, and if it goes wrong they are supposed to be able to say it was theirs to hand over. That is not about suspicion. That is what makes it possible to ever give anybody a key at all.
I believe in AI. I have built a company teaching people to use it and I am more convinced every month that it creates opportunity most people have not begun to reach for. I am not writing a cautionary tale. I do not think you should be afraid of this.
But I gave out keys without thinking about it, and I want to name that plainly rather than write around it, because I suspect you did too.
Anthropic's agents ran for 21.5 hours completely unsupervised and produced something Feng Zhang thought was worth reviewing. That was not recklessness. Somebody built the fence first, and then let it run hard inside the fence. The fence is what made the freedom possible.
OpenAI's agent was not evil. It had a job and no boundary, and it did what things with jobs and no boundaries do.
You do not need a research budget to copy the principle. Name a human owner for every agent in your business. Know how to shut each one off and roughly how long that takes. Give it the narrowest key that does the job. Put the click in front of anything you cannot undo.
Then let it run.
The fence is not the opposite of trust. The fence is what makes trust something you can actually give.
P.S. Go make the list. Not the policy, not the plan, just the list of what has access to what. Mine took forty minutes and two items on it genuinely surprised me. I would bet money yours does the same.

He teaches non-technical entrepreneurs how to use AI to amplify the skill and experience they already have, and he writes here about the parts of building a business that do not fit neatly into a framework. He has been to prison, through bankruptcy, and through two divorces, and he is more convinced than ever that what you do next matters more than what already happened. He would like to connect.
