# Draft post-incident report — INC-2026-0904

*This is a draft assembled from stored records. Nothing in it has been adopted, approved or signed off by anyone. Adoption is a registered action that goes through policy evaluation and leaves its own audit record; if this document were adopted, that record — not this file — would be the evidence of it.*

- **Incident:** `INC-2026-0904`
- **Document:** post_incident (draft)
- **Generated:** 2026-10-30T06:02:50.193966+00:00
- **Source:** https://265d0hsmwa.execute-api.us-east-1.amazonaws.com/api/v1/incidents/INC-2026-0904/draft/post_incident/export

## What happened *(draft)*

- An unauthenticated scanner probed the public application and wrote an instruction into its own request header, addressed to the model reading the alerts, asking for the incident to be closed and a file server wiped. The probing failed. (confidence 0.93)
  - *evidence:* `INC-2026-0904#hypothesis-0`, `SEC-0004-a`, `SEC-0004-b`, `SEC-0004-c`, `SEC-0004-d`
- network_flow:203.0.113.45->public-web:443 — vulnerability scan whose requests carry text addressed to the agent
  - *evidence:* `INC-2026-0904#chain-0`, `SEC-0004-a`, `SEC-0004-b`
- asset:public-web — path traversal on the upload endpoint, refused
  - *evidence:* `INC-2026-0904#chain-1`, `SEC-0004-c`, `SEC-0004-d`

## What was ruled out *(draft)*

- Ruled out: This is the authorised penetration test the request header says it is.
  - *evidence:* `INC-2026-0904#hypothesis-1`, `SEC-0004-e`

## What was done *(draft)*

- Nothing was executed. The plan was drawn up and did not run.
  - *evidence:* `INC-2026-0904`

## What was verified *(draft)*

- No verification is recorded, so nothing here says the incident was resolved rather than merely closed.
  - *evidence:* `INC-2026-0904`

*Exported documents do not update. An incident can reopen, a verification can land and an execution can be rolled back after this was written, and nothing on this page would show it. Check the references against the source before relying on it.*

*Adopting this would require the registered action `adopt_report`, which is scored and routed through policy evaluation like any other action. This file is not that.*
