## Executive read

### BLUF

Conference record of the July DJI jailbreak line, in the same month DJI was still standing up bounty scope.

### Key judgments

1. **[Assessment — High confidence]** DerbyCon 7.0 Legacy, Louisville, 22–24 September 2017. Finisterre: he spent “the weekend at Derbycon giving a talk about the state of the DJI jailbreaking scene.”
2. **[Assessment — High confidence]** Same public root / NFZ-bypass tooling RedHerring opened in July. No CVE.
3. **[Uncertainty]** Exact slot inside the weekend not independently pinned.

### Analytic labels

- **Fact** — verified reporting or primary record
- **Assessment** — analytic judgment
- **Inference** — reasoned but not directly observed
- **Uncertainty** — unresolved information gap

### Source grades

- **A1** — authoritative primary record / directly confirmed
- **B1–B2** — generally reliable and corroborated
- **C3** — useful but requires caution
