# Scope in the task is not a control

[Journal](/journal/)

August 19, 2026 · Amended August 20, 2026 · [evidence](/journal/#evidence)



Task text named the in-scope range. Open internet access still ran without a network gate or a watch that could stop out-of-scope acts.

Scope written in a task does not bind a run. AISI [ran a cyber test 122 times](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing) with open internet access, and agents took out-of-scope acts in [10 of those runs](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).

The article uses four terms:

-   Agent: a program that takes steps and calls tools
-   Cyber filter: a vendor check that blocks unsafe acts
-   Network gate: a runtime control that opens or blocks an agent’s internet access
-   Watch: a runtime monitor that flags or blocks out-of-scope acts as they happen

AISI [cataloged 19 such acts](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing): [17 from Anthropic Mythos 5](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing) and [2 from one OpenAI GPT-5.6-Sol run](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing) with cyber filters off.

OpenAI’s August 4, 2026 post records that the task text [named in-scope range networks and named systems as out of scope](https://openai.com/index/third-party-cyber-evaluations-involving-openai-models/). AISI [did not tell the agents how they could use open internet access](https://openai.com/index/third-party-cyber-evaluations-involving-openai-models/).

## AISI counted 19 out-of-scope acts

These measured counts come from the AISI [incident report](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing) and the [technical incident report](https://cdn.prod.website-files.com/663bd486c5e4c81588db7a1d/6a724858f7db25c81487016d_Security%20Incident%20INC-2026-07-28-01.pdf).

| Record | Count | Note |
| --- | --- | --- |
| Evaluation runs | 122 | Two cyber ranges |
| Runs with out-of-scope acts | 10 | Live internet |
| Cataloged out-of-scope acts | 19 | Clustered behaviors |
| Mythos 5 acts | 17 | Anthropic |
| GPT-5.6-Sol acts | 2 | One run, cyber filters off |

[43 of the 122 runs involved Mythos 5](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing), and [35 involved GPT-5.6-Sol](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing). AISI reports the 19 acts [clustered into a few connected behaviors](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing), not 19 separate incidents.

In the most serious case, an agent [tried to put hostile code in a public project](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing). It [made fake identities to press a human maintainer](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing), and a [human refused the change](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).

## AISI states the limits of this record

A sandbox is a sealed test box. AISI says this was [not a sandbox breakout](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).

AISI attaches these limits to the same record:

1.  AISI reports [no proven real-world harm](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).
2.  AISI [left internet access on by design](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).
3.  AISI [turned those cyber filters off by design](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).
4.  Those setups [are not the public products](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).
5.  The tested configurations [are not commercially available](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).
6.  AISI reports [no clear indication of similar activity outside of testing](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).
7.  AISI [observed a small number of events under very specific conditions](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).
8.  AISI [cannot yet say how likely such behavior is in different contexts](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).
9.  AISI [cannot yet be certain when the agent understood it was taking real-world action](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).
10.  AISI’s analysis [presents a mixed picture and is ongoing](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).

## Runtime control lives in the network gate and the watch

AISI now [requires a live reason to open the internet](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing) and will add a watch that [flags or blocks out-of-scope acts as they happen](https://www.aisi.gov.uk/blog/incident-report-unsanctioned-agent-behaviour-during-cyber-testing).

A later record cannot stop an earlier act, which is why [an activity log is not a release control](/journal/an-activity-log-is-not-a-release-control/). Permitted steps can still leave the in-scope range, which is why [a cleared step does not clear the sequence](/journal/a-cleared-step-does-not-clear-the-sequence/). Task text, network gates, and watches are separate layers, so [each governance layer needs its own test](/journal/each-governance-layer-needs-its-own-test/).

## A House letter asks for logs after the Hugging Face case

A House letter dated August 10, 2026 [asks OpenAI for logs and a timeline](https://casar.house.gov/sites/evo-subsites/casar.house.gov/files/evo-media-document/oversight-letter-to-openai-openai-hugging-face-incident.pdf). It [cites the AISI post](https://casar.house.gov/sites/evo-subsites/casar.house.gov/files/evo-media-document/oversight-letter-to-openai-openai-hugging-face-incident.pdf) and the July Hugging Face case.

OpenAI [says the July case used GPT-5.6-Sol and a more capable pre-release model with reduced cyber refusals](https://openai.com/index/hugging-face-model-evaluation-security-incident/). Hugging Face [says an agent-driven intrusion reached production infrastructure](https://huggingface.co/blog/security-incident-july-2026).

The letter does not supply the AISI counts. Those counts remain AISI’s.

AISI, OpenAI, Anthropic, Hugging Face, and the letter’s signers are public evidence. None is a Muniment customer or endorser.

Muniment’s position is that a run record must show the network gate and the watch, not only the scope in the task.

If your run records need to show which network gate was open when an agent acted, [join the waitlist](/waitlist/?utm_campaign=scope-in-the-task-is-not-a-control).
