CTI STIX Workbench

CTI STIX Workbench keeps the analyst workflow in Obsidian. You write normal Markdown, connect evidence with wiki links and Canvas, edit structured STIX properties when you need them, and export a reviewable Bundle without sending your vault to a hosted service.

What it does

• Provides catalog-driven property editing for standard STIX 2.1 objects.
• Imports validated STIX 2.1 Bundles into typed, linked Markdown notes.
• Validates an active note and its connected graph against pinned local schemas.
• Visualizes STIX JSON or connected notes as an interactive, icon-based graph.
• Gives explicit, readable diagnostics instead of silently changing bad data.
• Persists missing STIX identifiers safely and keeps them stable across exports.
• Exports collision-safe JSON Bundles to a vault-relative folder.
• Runs offline on Obsidian desktop without runtime network calls or telemetry.

Visualize before you export

Open a local STIX Bundle, object, object array, or connected typed note graph in the STIX viewer. It renders official OASIS icons, authored Relationships, top-level references, and unresolved targets in one read-only workspace. Pan, zoom, rearrange, filter, and inspect the real STIX properties without modifying the source or sending investigation data off-device.

The viewer follows Obsidian desktop themes and adapts to desktop split panes and popout windows. Its Maltego-style component graph groups connected intelligence around relationship hubs and shows authored Relationships by default, with dense metadata references available on demand. Hover or focus a connection for its semantic label, then select an icon or connection to inspect its complete data in the side panel.

Plugin or vault template?

Project	Use it for
CTI STIX Workbench (this repository)	Editing, validation, graph traversal, and Bundle export.
CTI Investigation Vault	A clean starting structure with all STIX templates, the official OASIS APT1 Bundle, and 76 browseable generated notes.

They are independent. The plugin never creates, replaces, or uploads your vault. This repository contains plugin source and test fixtures, not a distributable vault. The separate vault repository owns its README, attribution, and analyst workspace; automation proposes only generated templates and example data.

Install

Open the CTI STIX Workbench community page for the current Obsidian listing and installation status.

For a manual installation, download main.js, manifest.json, and styles.css from the latest release, then place them in:

<your-vault>/.obsidian/plugins/cti-stix-workbench/

Restart Obsidian, open Settings → Community plugins, and enable CTI STIX Workbench. Obsidian 1.8.10 or newer is required.

A five-minute first run

1. Choose a starting point:

   • Run Create STIX object for a new manually authored object, then use Edit STIX properties to complete its catalog-defined fields.
   • Run Create analyst workflow for a guided triage, assessment, review, or feedback Note linked to the active investigation.
   • Open a local STIX Bundle such as Examples/OASIS APT1/apt1.json and run Import STIX Bundle as notes. Imported notes are already populated from the source objects and remain editable.

2. Connect related notes with ordinary [[wiki links]] for analyst context.

3. Add an exportable relationship as a list item, for example:

   - stix:uses [[Target note]]
   

4. Run Validate active STIX graph and review any diagnostics.

5. Run Open in STIX viewer to inspect and temporarily arrange the graph.

6. Run Export active STIX graph to write a STIX Bundle to Exports/.

For investigation-led work, keep the typed investigation Note active when you validate or export. Its object_refs wiki links provide the Bundle scope under the default traversal settings. Use folder or Canvas export when that is the more accurate sharing boundary.

The APT1 example imports 76 objects, including 30 typed Relationships. It is the official OASIS example and demonstrates that created_by_ref is optional.

Ordinary links remain useful context and appear in Graph view. They become STIX Relationships only when you use the explicit stix:<relationship-type> form.

Canvas, folder, and whole-vault commands are also available. Canvas semantics come only from directed file-node edges labeled stix:<relationship-type>. Import creates Markdown notes and an import overview, while Canvas generation remains a separate action. Create one manually or run Generate canvas from current folder after importing when you want a visual, explicit scope. Existing Relationship notes become labeled edges without creating duplicate STIX Relationships. Whole-vault export always requires confirmation and can be cancelled before any Bundle is written.

Privacy and safety

Validation and export happen on your device. The installed plugin does not call remote APIs, load schemas from the internet, or transmit vault contents.

Keep operational vaults private. Do not commit credentials, customer data, restricted intelligence, malware samples, exploit payloads, or personal data to a public repository.

CTI STIX Workbench is a desktop-only Obsidian plugin. Mobile installations are not supported.

Obsidian scorecard network disclosure

The Obsidian scorecard reports three network-request calls in main.js. These are a scanner false positive from the bundled antlr4ng STIX-pattern parser: one local token-buffer method named fetch and two calls to that method. They read lexer tokens from memory and are not the browser or Obsidian network API. The plugin contains no runtime HTTP client, telemetry, or remote-data path, and no vault data leaves the device.

Development

Requirements: Node.js 22.22.1 or newer and Corepack.

corepack enable
corepack pnpm install --frozen-lockfile
corepack pnpm format:check
corepack pnpm verify:sources
corepack pnpm test
corepack pnpm lint:biome
corepack pnpm lint:marketplace
corepack pnpm typecheck
corepack pnpm build
corepack pnpm smoke
corepack pnpm check:release

Corepack pins pnpm for reproducible installs. Biome is the formatter, baseline linter, and staged-file checker. ESLint remains only as the type-aware Obsidian Marketplace gate because Biome cannot yet express every Obsidian-specific rule. The project does not use Prettier. Husky runs Biome through nano-staged before a commit, commitlint validates Conventional Commit messages, and the pre-push hook runs both linters, typechecking, tests, a production build, and the bundle smoke test through corepack pnpm check:push.

The validation toolchain uses checksum-pinned OASIS STIX 2.1 sources under standards/. Generated runtime files stay out of Git; small declaration files remain committed so source review and type-aware linting work from a clean clone.

Releases

Maintainers add release notes under ## Unreleased in CHANGELOG.md, then run the Prepare release workflow to choose a patch, minor, or major increment. That workflow opens a reviewable version PR. After it is merged, the Release Obsidian plugin workflow creates an annotated tag, verifies the project, attests the three release files, and opens a draft release for manual review.
