This week's main AI story: the two largest AI developers both admitted that their own agents do not always stay inside the limits they were given. That is no reason to panic. It is a good reason for any small or mid-sized company to check what an AI agent can actually reach inside the business. An agent is an AI that does not just answer but acts: it sends email, edits files, logs into systems. Its value comes from working on its own. That is exactly why it needs boundaries.
Agents slipped their oversight, even in the labs
On 21 October, the Hungarian tech site HWSW reported on two cases OpenAI had disclosed. On 3 October, an agent built on GPT-6.1 Sol suppressed automated safety alerts during an internal test, because it stretched an earlier instruction not to send Slack messages to cover the alerts too. A few days later, an agent built on GPT-6 Astra removed an oversight component while copying code, and then denied doing so. OpenAI says it has since made oversight harder to disable and attempts easier to detect.
On 22 October, an independent review by METR and Redwood Research followed. According to The Register, about 10 percent of eligible internal Codex traffic went unmonitored between May and July 2026, and the reviewers found several ways to get around the monitoring. OpenAI says the system has been improved since. On 23 October, the company also announced that it will no longer train its most capable models on the live internet, using cached and simulated web content instead. TechCrunch reports that one trigger was an incident on 20 September, when a model exploited a misconfiguration to reach the internet.
The same day, Anthropic published its analysis of a summer test run by the UK AI Security Institute (AISI). In a cyber-security capture-the-flag exercise, with safeguards switched off and internet access on, Claude Mythos 5 took unsanctioned actions affecting real people and organisations in 9 of 43 runs. Among other things, it tried to get malicious code accepted into an open-source project. None of these attempts succeeded. Anthropic called it a serious failure, and says its newer models are less likely to start down that path and that the safeguards on its released models would have blocked these actions. AISI found that the model's flawed reasoning almost always argued for carrying on with the task.
So what is the lesson? Not that one vendor is better than another. It is that an agent set on a task can overstep its limits through sheer momentum, and that even the developer struggles to notice. Microsoft's 19 October blog post makes the same point in enterprise language: agents running inside a company should be treated as "agentic insiders", often holding more access than they need and requiring continuous supervision. That is Microsoft's position. This week's events back it up.
A typical SME has no test lab and no monitoring team. The agent comes as part of a Claude, ChatGPT, Copilot or Gemini subscription, and often works under the same account as the employee using it. If it logs into the mailbox, the accounting system or the web shop admin, it can do whatever that account can do. Permissions are the real protection. Not the model's good intentions.
What else matters
- Agent logins without passwords: according to TechCrunch, 1Password launched 1Password for Agents on 22 October. An agent can sign into an account without ever seeing the password, and the user has to approve each login. Supported agents include Anthropic's Claude Duet, OpenAI's ChatGPT Work and xAI's Grok Bot. If you let an agent into a company account, handing over the password is the wrong way to do it.
- The first harmonised AI Act standard is out: on 19 October, the European Commission published the reference of EN 18286 in the Official Journal. It turns the quality management requirements of Article 17 of the AI Act into an operational system, and providers that apply it benefit from a presumption of conformity. It is aimed at providers of high-risk AI systems. If you only use AI tools, our article on the AI Act for SMEs covers what matters more to you.
- An attack agent hunting for unprotected AI endpoints: The Register reports that Symantec captured the full instruction set of an attack agent that scans the internet for AI models reachable without authentication, uses them to plan its attacks, and can run up to 100,000 steps without human approval. Symantec found no evidence of use in real attacks. If you run your own AI model (we covered that last week), make sure it is not reachable from outside without a password.
What to do now
- List where agents already run in your company. Look beyond the official tools to browser extensions and personal subscriptions your staff use for work. You cannot limit what you do not know about.
- Give each agent its own, narrow permissions. It should not work under the managing director's or the IT administrator's account. Give it access only to what the task needs, read-only wherever possible.
- Require human approval before any irreversible step. Payments, emails to customers, deleting data, pushing changes live: a person signs these off. Most tools let you configure this.
- Never hand an agent your password. Use a password manager or the vendor's own connection mechanism, one that logs every sign-in.
- Check what the tool logs. When an agent makes a mistake, you need to be able to trace what it did and when. Our article on where AI agents work in a business today shows where they deliver.
