3.1.2. Update Servers
To download the newest updates for Aurora and our signatures, you need an active internet connection. The endpoint performing the update needs to reach our update servers to do this.
For a detailed and up to date list of our update and licensing servers, please visit https://www.nextron-systems.com/hosts/.
You do not need an active internet connection to run Aurora on an endpoint. This is only needed if you want to update to the latest Aurora or signature versions.
3.1.3. Define an Antivirus / EDR Exclusion
It is recommended to exclude Aurora from your Antivirus / EDR solution.
Depending on your architecture and whether Aurora was installed or started interactively from a temporary directory, the exclusion paths are:
For an installed Aurora
C:\Program Files\Aurora-Agent\aurora-agent-64.exe C:\Program Files\Aurora-Agent\aurora-agent.exe
For a interactively started Aurora the path you have used for extraction. For example:
3.2. Quick Installation
Extract the program package into a temporary folder (e.g.
Make sure to place the license file (
*.lic) into the extracted folder
Change directory to the extracted folder (
Run one of the following commands (with/without GUI)
C:\aurora>aurora-agent.exe --install C:\aurora>aurora-agent.exe --install --dashboard
Verify new events in the local "Application" event log (Event Viewer) or the Aurora Dashboard
Run the following commands to get details on the current status of the agent
C:\aurora>aurora-agent.exe --status C:\aurora>aurora-agent.exe --status --trace
See the Function Tests section for ideas on how to test Aurora is working as expected.
3.3. Manual installation
3.3.1. Install Aurora
You can install the agent using the following command line from command line terminal that has been started "As Administrator".
After the installation the agent, configuration files and rules reside in
C:\Program Files\Aurora Agent\.
It automatically copies all rule files located in the sub-folders
signatures\sigma-rules folder contains the current open source rule set maintained
in the Sigma repository.
custom-signatures folder can be used to add your own sigma rules.
Aurora comes with with 4 configuration presets that we encourage you to explore and use:
The different presets are explained in more detail in the chapter Configuration.
An installation that uses the preset named "reduced" would look like this:
C:\aurora>aurora-agent.exe --install -c agent-config-reduced.yml
3.3.2. Custom Settings
Adding your own Sigma rules or IOCs is described in chapter Custom Signatures and IOCs.
The preferred way is to add them to the
custom-signatures folder before you install Aurora.
All the flags that you use after
--install get written to the configuration file
agent-config.yml in the
C:\Program Files\Aurora Agent\ folder and will be used by the service.
A typical command to install Aurora would look like this
C:\aurora>aurora-agent.exe --install --activate-responses
3.3.3. Uninstall Aurora
To uninstall the agent simply run the following command:
C:\Program Files\Aurora-Agent>aurora-agent.exe --uninstall
If the uninstaller fails due to unknown errors, you can uninstall Aurora manually with these commands (Run from an administrative shell)
C:\Users\nextron>sc stop aurora-agent C:\Users\nextron>sc delete aurora-agent C:\Users\nextron>rmdir /s /q "C:\Program Files\Aurora-Agent" C:\Users\nextron>schtasks /Delete /F /TN aurora-agent-program-update C:\Users\nextron>schtasks /Delete /F /TN aurora-agent-signature-update
