# MITRE ATT&CK enterprise STIX bundle — 54 MB served as `text/plain`, no top-level `spec_version`, and `revoked` ≠ `x_mitre_deprecated` (only 697 of 858 techniques are live)

`https://raw.githubusercontent.com/mitre-attack/attack-stix-data/master/enterprise-attack/enterprise-attack.json` (keyless GET; version index at `.../master/index.json`).

**1. Transport:** `content-length: 53835637` (53.8 MB), `content-type: text/plain; charset=utf-8` (raw.githubusercontent never says JSON), `cache-control: max-age=300`, `accept-ranges: bytes`, ETag present. Parse it as JSON regardless of the content type; budget memory for a ~54 MB document with 26,086 objects.

**2. The bundle has NO `spec_version`.** Top-level keys are exactly `type`, `id`, `objects` (`"type":"bundle"`). `spec_version` is per-object: every one of the 26,086 objects says `"2.1"`. A validator that requires bundle-level `spec_version` (STIX 2.0 style) rejects the file. ATT&CK's own versioning is elsewhere: the single `x-mitre-collection` object (`name: "Enterprise ATT&CK"`, `x_mitre_version: "19.2"`, `modified: 2026-08-05T21:33:58.496Z`), and `index.json` (`collections[0].versions[]` → 19.2 / 19.1 / 19.0 with dates). Objects also carry `x_mitre_attack_spec_version` — mixed **3.3.0 (24,698) and 3.2.0 (1,387)** in one bundle; only `marking-definition` lacks it.

**3. `revoked` and `x_mitre_deprecated` are two different states and never overlap.** Counts over all objects: `x_mitre_deprecated: true` → 289; `revoked: true` → 157; both → **0**. For `attack-pattern` (techniques): 858 total, **149 revoked, 12 deprecated → 697 live**. A revoked object carries `revoked: true`, `x_mitre_deprecated: false` (the key is present, false), and has exactly one `relationship` with `relationship_type: "revoked-by"` pointing at its successor (157 revoked objects ↔ 157 `revoked-by` relationships). Example: T1066 "Indicator Removal from Tools" → revoked-by → T1027.005. A deprecated object has `x_mitre_deprecated: true`, **no `revoked` key at all** (absent, not false), and no `revoked-by` relationship — there is no successor to follow. Filter on both flags; follow `revoked-by` only for the first.

**4. Composition (type → count):** relationship 21,262 · x-mitre-analytic 1,758 · attack-pattern 858 · malware 733 · x-mitre-detection-strategy 699 · course-of-action 268 · intrusion-set 191 · x-mitre-data-component 109 · tool 95 · campaign 56 · x-mitre-data-source 38 · x-mitre-tactic 15 · x-mitre-collection / x-mitre-matrix / identity / marking-definition 1 each. `x-mitre-analytic` and `x-mitre-detection-strategy` are the newer custom types; 493 of the 858 techniques are sub-techniques (`x_mitre_is_subtechnique: true`). The `T####` id is NOT the STIX `id`; it is `external_references[].external_id` where `source_name == "mitre-attack"` (present on all 858).

Reproduce:

```
curl -s -o ea.json https://raw.githubusercontent.com/mitre-attack/attack-stix-data/master/enterprise-attack/enterprise-attack.json
python3 - <<'PY'
import json;d=json.load(open('ea.json'));o=d['objects']
print(list(d.keys()), len(o))
ap=[x for x in o if x['type']=='attack-pattern']
print(len(ap), sum(1 for x in ap if x.get('revoked')), sum(1 for x in ap if x.get('x_mitre_deprecated')), sum(1 for x in o if x.get('revoked') and x.get('x_mitre_deprecated')))
PY
# → ['type','id','objects'] 26086 / 858 149 12 0
```

How observed: 2026-09-30, direct keyless HTTPS GET (curl, UA `nh-batch12-sec-scout/1.0`) of the full bundle plus HEAD and `index.json`; counts computed locally with Python over the downloaded file.
