ThreatLens

ThreatLens extracts candidate indicators of compromise (IoCs) from cyber threat intelligence reports, checks them for quality issues (duplication, missing context and likely false positives) and stores them in a SQLite repository with a quality score, browsable from a web dashboard.

ZEIT3118 Capstone, UNSW Canberra, 2026.

Requirements

• Python 3.12+
• For the default llm extraction engine: an Ollama server with the verifier model pulled (the evaluation runs use qwen3.5:9b). The python engine needs no LLM.

Installation

python -m pip install "threatlens-cti[dashboard]"

The package is threatlens-cti. It installs the threatlens Python package and the threatlens, threatlens-init, threatlens-ingest, threatlens-calibrate and threatlens-dashboard commands; each takes --version. This is a beta (0.x): behaviour may still change between minor versions. Leave out [dashboard] if you only need the command line (no FastAPI, Uvicorn or Datasette); threatlens-dashboard then tells you how to add it.

Setup

threatlens init

The setup wizard asks for the data folder, the Ollama URL (tested live), the models (picked from those the server has pulled), the dashboard address and, optionally, the quality weights. It shows a summary, then writes threatlens.conf, creates the database and can calibrate the LLM settings for your hardware. Re-run it any time: the current values are the defaults. threatlens init --help lists the options for scripted (--non-interactive) setups. Until setup is done, the commands print a warning naming the missing step and, in a terminal, offer to start the wizard.

threatlens.conf holds every per-machine setting: Ollama URL, verifier and profiler models, LLM performance tuning ([llm]), data folder, default database, dashboard address and quality-score weights. Besides the wizard, the dashboard's Configuration page and threatlens-calibrate also write it:

threatlens-calibrate                      # re-benchmark the configured model and server
threatlens-calibrate --model qwen3.5:9b --ollama-url http://host:11434 --save

Where files live

On Windows, config and data share %LOCALAPPDATA%\threatlens (e.g. C:\Users\you\AppData\Local\threatlens); on macOS, ~/Library/Application Support/threatlens. THREATLENS_CONF moves the config file; THREATLENS_HOME or [paths] data_dir in threatlens.conf moves the data folder (db/ and reports/).

Usage

# Web dashboard: browse, upload, ingest, configure (http://127.0.0.1:8000)
threatlens-dashboard
threatlens-dashboard --host 0.0.0.0 --port 8000   # reachable from the local network

# Export: the dashboard's Export page (/export), or the Export button on each tab.
# Indicators, reports, quality flags and sightings as CSV or JSON; indicators
# also as a STIX 2.1 bundle for MISP / OpenCTI. From Python:
#   from threatlens.exporters import export
#   export(session, "indicators", "stix", filters={"min_score": 65})

# Ingest one report: extract, quality-check, store, rescore
threatlens-ingest report.pdf --db ~/.local/share/threatlens/db/threatlens.db --engine llm

# Inspect one report: extraction only, no database
threatlens report.pdf
threatlens report.pdf --engine python -o result.json

# Quality-check extractor JSON without a database
python -m threatlens.quality.quality_checker result.json

# Create or upgrade a database by hand (init does this for you)
python -m threatlens.db.migrate [path/to/file.db]

The dashboard has no login. It listens on 127.0.0.1 (this machine only) unless you choose otherwise in threatlens init or pass --host; anyone who can reach it can edit and delete data.

The full documentation ships with the package: start threatlens-dashboard and open http://127.0.0.1:8000/docs/. The same pages are in the repository under src/threatlens/docs/.

Development

Source: github.com/m0ngrl/threatlens-cti. From a checkout:

python3 -m venv .venv                # Windows: py -m venv .venv
source .venv/bin/activate            # Windows: .venv\Scripts\activate
python -m pip install -e ".[dev,dashboard]"
threatlens init                      # writes threatlens.conf in the repo root
pytest

pyproject.toml is the source of truth for dependencies; dev adds pytest, ruff, mypy, build and twine. For the exact versions the project is tested with, install the pinned runtime set first:

python -m pip install -r requirements.txt
python -m pip install -e . --no-deps

In a checkout, threatlens.conf, db/ and docs/database/CTI/ are gitignored, and cp threatlens.conf.example threatlens.conf is an alternative to the wizard.

Always create and change the schema through Alembic, never create_all(). The migrations ship in the package (src/threatlens/migrations/); from the repo root, alembic upgrade head and alembic revision --autogenerate -m "..." use alembic.ini.

The evaluation corpus (third-party reports) is not distributed; reports can be fetched from the ORKL archive with .dev_tools/orkl_scraper.py. To ingest a folder of reports in resumable batches into a fresh database:

python .dev_tools/run_ex_pipeline.py --db-path db/exN_threatlens.db --batch 1/3
