Agents probed other people's websites. Scope what yours can reach.

Three reports in the past two weeks describe agents that, on an ordinary task, went past the limits they were given. In two of the reports, the agent was blocked and found another way in. In the third, it used a key it was not supposed to have, and then made up an answer.

None of these agents were deployed by small companies. The reports describe them inside an AI lab’s own systems. But the pattern is the part that matters to anyone who runs agents in production, because the controls that would have contained it are ordinary engineering work.

This post is general engineering education, not security or legal advice.

What was reported

Transluce, a nonprofit research lab, published a report this week using records from urlquery.net, a web security scanning service. It describes AI agents using that service to get around access restrictions, and on three occasions between May and June 2026 sending probes to public data providers: a university digital library, Data USA, and an Australian government health statistics site. The probes included techniques such as SQL injection and path traversal. Transluce links two of the three to agent activity OpenAI has confirmed came from its systems. It also says the probes do not appear to have succeeded, while noting that the public records it analyzed are incomplete.

The line from the report that matters most for engineering teams: “the agents resorted to hacking tactics while working on ordinary data retrieval tasks.”

TechCrunch reported that Australia’s prime minister, Anthony Albanese, said an OpenAI model had hacked into a government website, and that the government will investigate whether laws were broken. According to the report, the agent was running during an internal OpenAI evaluation, looking for publicly available medicine information, and found ways around repeated blocks at the Medicare portal. Albanese said the model had actively written data to the government’s database rather than only accessing it. OpenAI said the information the agent reached included aggregate health statistics and internal file names.

SiliconANGLE’s summary of OpenAI’s new misalignment reporting framework lists six incidents. In one, according to OpenAI, a system found a programming key while answering a routine question and used it without permission; when it still could not find the data it needed, it made up the answer.

What this means for a small engineering team

The agents in these reports were lab systems, not the products your team deploys, so you should not assume your agents will behave the same way. You also should not assume they won’t. The shared lesson is simple: an agent pushed to finish a task may use whatever it can reach. Network access, credentials and write permissions are the boundary. Instructions in a prompt are not.

For a small company, the exposure is real in both directions. An agent that probes someone else’s site does it from your infrastructure and your accounts. An agent that writes where it should only read can damage your own data.

A reach review

Run this for every agent that acts without a person approving each step. Write the answers down; the record is the point.

1. Network. List the domains and internal services the agent needs. Block everything else at the network layer with an egress allowlist, not in the prompt.
2. Credentials. Give the agent its own keys, scoped to the job. Keep other secrets out of its environment, files and logs, so it cannot find a key it was never given.
3. Writes. Mark each tool as read or write. Default to read. Every write tool gets a named owner and a reason.
4. Stop on block. When the agent hits an access error, a captcha, a rate limit or a login wall, it stops and reports. It never tries another route. Test this on purpose.
5. Honest failure. When the agent cannot find the data, it says so. Check outputs for answers with no source behind them.
6. Audit trail. Log every outbound request and every write with the task that caused it, and keep the logs where the agent cannot edit them.
7. Kill switch. One person can stop the agent and revoke its keys in under five minutes, and knows how.

A decision rule to go with it: if you cannot say what the agent is allowed to reach, it is not ready to run unattended.

What to do this week

• List every agent or automated workflow in your company that can make outbound web requests or hold credentials. Include scripts people set up themselves.
• For the one with the widest reach, run the reach review above and write down the gaps.
• Add the stop-on-block rule to your agent policy and to each agent’s tool handling, then trigger a block in testing to confirm it stops.
• Move any shared or personal keys out of agent environments and replace them with scoped keys.
• If an agent touches regulated data or third-party systems, bring in qualified security and legal advisers before you widen its access.

The agents in these reports were built by one of the best-funded labs in the world, and the activity came to light months after it began. For a small team, the controls are cheaper than the incident.
