YARA Designer: TheHive/Cortex Responder

This responder sends a thehive:case to a listener which then creates a YARA rule based on it.

Setup

1. Cortex needs to have cortexutils installed at operating system level:

   $ sudo pip3 install cortexutils
   

2. Upload contents of responder/ to CORTEX_RESPONDERS/YaraDesigner/ on Cortex host.
3. Restart TheHive and Cortex:

   $ sudo systemctl restart cortex thehive
   

4. Enable the Cortex Responder:
   1. Log into Cortex with your TheHive user.
   2. Click "Organization" in the top bar.
   3. Click the "Responders" tab.
   4. Click the "+ Enable" link at the far right on the entry "YARA Designer ".
   5. Configure options and click "Save".
   6. Click "Responders" in the top bar and verify that it is listed on the Responders page.
