Thank you to all of our users for their feedback, bug reports, and contributions to the project. As of May 8, 2023, Attack Range Local has been deprecated and archived.

Great News! https://github.com/splunk/attack_range now supports deploying Attack Range Locally (just like this repo used to). It's a one-stop-shop for all of your simulation needs. That repo brings the functionality of Attack Range Local and Attack Range Cloud into the Attack Range Repo. It is actively maintained and in use by the Splunk Threat Research Team on a daily basis.

The Attack Range is a detection development platform, which solves three main challenges in detection engineering. First, the user is able to build quickly a small lab infrastructure as close as possible to a production environment. Second, the Attack Range performs attack simulation using different engines such as Atomic Red Team or Caldera in order to generate real attack data. Third, it integrates seamlessly into any Continuous Integration / Continuous Delivery (CI/CD) pipeline to automate the detection rule testing process.

Attack Range can be built in three different ways:

• locally with vagrant and virtualbox
• cloud using terraform and AWS or Azure, see attack_range
• cloud-only see attack_range_cloud

The virtualized deployment of Attack Range consists of:

• Windows Domain Controller
• Windows Server
• Windows Workstation
• A Kali Machine
• Splunk Server
• Phantom Server
• Caldera Server

Which can be added/removed/configured using attack_range_local.conf. More machines such as Phantom, Linux server, Linux client, MacOS clients are currently under development.

The following log sources are collected from the machines:

• Windows Event Logs (index = win)
• Sysmon Logs (index = win)
• Powershell Logs (index = win)
• Network Logs with Splunk Stream (index = main)
• Attack Simulation Logs from Atomic Red Team and Caldera (index = attack)

Attack Range supports different actions:

• Build Attack Range
• Perform Attack Simulation
• Destroy Attack Range
• Stop Attack Range
• Resume Attack Range
• Dump Attack Data

python attack_range_local.py -lm

• Destroy Attack Range Local

python attack_range_local.py -a destroy

• Stop Attack Range Local

python attack_range_local.py -a stop

• Resume Attack Range Local
