How to use the SecurityTrails Splunk Addon
1. Open a free Splunk account at https://www.splunk.com.
Verify your email and you are ready to go.
2. Login to your splunk.com account.
3. Download the Splunk version depending on your operating system.
In our case, we downloaded Splunk Enterprise for Linux from
Download the .tgz 326.9 MB version.
4. Once done, extract the tar.gz file.
Move to the splunk/bin directory.
This will ask you to set an admin username and password.
And then it will start the Splunk server at your localhost:8001 (or 8000, I don't remember).
If the installation finished OK, it should display something like:
Waiting for web server at http://127.0.0.1:8000 to be available........ Done
The Splunk web interface is at http://127.0.0.1:8000
5. Download the required files.
Latest SecurityTrails Splunk Addon file from github.com/secops4thewin/TA-securitytrails or (at the time of writing this guide the latest stable version) version 1.4.0:
Splunk Common Information Model App from: splunkbase.splunk.com/app/1621/
6. Open http://localhost:8000 or http://127.0.0.1:8000
Enter your admin username and password.
Locate the Gear icon at your top left corner, as you see below:
Then, at your right top area, locate an option called 'Install app from file':
- Click Install App from File, and then upload the files you downloaded previously (ST Splunk Addon and Splunk Common Information Model App).
- Restart the Splunk server after each upload.
- Login back to your Splunk admin panel.
7. Configure the SecurityTrails Addon. Move to the left top corner, you will see an 'Apps' menu.
- Click on the ST addon.
- Move to 'Addon Settings'
- Set your API Key
- Set any index name, something like stindex for example.
That's it. At this point, the APP should be configured and ready to work.
How can I perform manual queries against the SecurityTrails API?
Inside the SecurityTrails App interface, click on 'SecurityTrails Hunt':
- Select the API actions you want to perform.
- Enter a Search Description that will be stored in the Splunk index.
- Hit Submit button.
For example, in the following screenshot you will see we will be fetching the Get Whois API endpoint, then we can enter any description, enter the name of the domain we want to investigate, and finally hit Submit button.
The results will be displayed in the second 'Search' window after 30 seconds.
Scroll down a little bit, then hit Refresh icon, as you see below:
The results will be displayed immediately.
