Splunk Attack Range v5

The Splunk Attack Range builds instrumented cloud environments (AWS, Azure, GCP), simulates attacks, and forwards data into Splunk for detection development and testing.

What it does:

• Build labs — Deploy a small, production-like lab (Splunk, Windows/Linux servers, optional Kali, Zeek, etc.) via Terraform and Ansible.
• Simulate attacks — Run Atomic Red Team (and other) techniques to generate real telemetry.
• Share access — Use WireGuard VPN; generate additional client configs to share the range with others.

Getting started

Preferred: Docker Compose

1. Prerequisites: Docker and Docker Compose. Configure your cloud provider (AWS, Azure, or GCP) and mount credentials as below.

2. Clone and start:

   git clone <repo-url>
   cd attack_range_2
   docker compose -f docker/docker-compose.yml up

3. Use the app or API:

   • Web app: open http://localhost:4321 — build/destroy ranges, view status, run simulations, share access.
   • API: http://localhost:4000 — REST API; interactive docs at http://localhost:4000/openapi/swagger.

4. Build a range (two steps):

   • In the app: pick a template (e.g. aws/splunk_minimal_aws) and start the build. When status is Waiting for VPN, download the WireGuard config, connect with WireGuard, then continue the build.
   • Or via API: POST /attack-range/build with {"template": "aws/splunk_minimal_aws"}, poll GET /attack-range/status/<id>, use the returned WireGuard config, connect, then POST /attack-range/build with {"attack_range_id": "<id>"}.

5. CLI in Docker (optional):

   docker compose --profile cli -f docker/docker-compose.yml run --rm attack_range build -t aws/splunk_minimal_aws

   Other actions: destroy, simulate, apply-role, share. See Detailed documentation for CLI usage and flags.
