Introduction
The Devo IOC Exporter Connector for ThreatQ enables the automatic dissemination of IOCs from a ThreatQ data collection to a Devo Lookup List. The connector utilizes Devo's Python SDK, devo-sdk
to make calls to the Devo API via their load balancers.
This connector does not ingest any data back into ThreatQ.
Prerequisites
Review the following requirements before attempting to install the connector.
Time Zone
The time zone steps are for ThreatQ v5 only. ThreatQ v6 users should skip these steps.
You should ensure all ThreatQ devices are set to the correct time, time zone, and date (UTC is recommended), and using a clock source available to all.
To identify which time zone is closest to your present location, use the timedatectl
command with the list-timezones
command line option.
For example, enter the following command to list all available time zones in Europe:
Europe/Amsterdam
Europe/Athens
Europe/Belgrade
Europe/Berlin
Enter the following command, as root, to change the time zone to UTC:
Devo API Certificate, Private Key, 509 Chain CA
The integration requires the following:
- Devo API Certificate (<org>.cert)
- Private Key (<org>.key)
- 509 Chain CA (chain.crt)
These items has be obtained by going to Administration -> Credentials -> X.509 Certificates on your Devo instance.
Integration Dependencies
The integration must be installed in a python 3.6 environment.
The following is a list of required dependencies for the integration. These dependencies are downloaded and installed during the installation process. If you are an Air Gapped Data Sync (AGDS) user, or run an instance that cannot connect to network services outside of your infrastructure, you will need to download and install these dependencies separately as the integration will not be able to download them during the install process.
Items listed in bold are pinned to a specific version. In these cases, you should download the version specified to ensure proper function of the integration.
Dependency | Version | Notes |
---|---|---|
threatqsdk | >=1.8.1 | N/A |
threatqcc | >=1.4.1 | N/A |
python-dateutil | N/A | N/A |
dev-sdk | ==3.6.2 | Pinned |
cryptography | ==38.0.4 | Pinned |
Installation
Upgrading Users - Review the Change Log for updates to configuration parameters before updating. If there are changes to the configuration file (new/removed parameters), you must first delete the previous version's configuration file before proceeding with the install steps listed below. Failure to delete the previous configuration file will result in the connector failing.
- Download the connector integration file from the ThreatQ Marketplace.
- Transfer the connector whl file to the
/tmp/
directory on your instance. - SSH into your instance.
- Move the connector whl file from its
/tmp/
location to the following directory:/opt/tqvenv

Usage
Use the following command to execute the driver:
Command Line Arguments
This connector supports the following custom command line arguments:
Argument | Description |
---|---|
-h , --help |
Review all additional options and their descriptions. |
-ll LOGLOCATION , --loglocation LOGLOCATION |
Sets the logging location for the connector. The location should exist and be writable by the current. A special value of 'stdout' means to log to the console (this happens by default). |
-c CONFIG , --config CONFIG |
This is the location of the configuration file for the connector. This location must be readable and writable by the current user. If no config file path is given, the current directory will be used. This file is also where some information from each run of the connector may be put (last run time, private oauth, etc.) |
-v {1,2,3} , --verbosity {1,2,3} |
This is the logging verbosity level where 3 means everything. |
-n, --name |
Optional - Name of the connector (Option used in order to allow users to configure multiple Intelligence Mailbox connector instances on the same TQ box). |
--cron | ThreatQ v6 Only - creates a CRON entry for the connector based on a pre-loaded ThreatQ template. See the CRON section for more details. |
Accessing Connector Logs
ThreatQ version 6 aggregates the logs for all custom connectors to its output container. You can access the container's log using the following command:
The connector log directory was created in 10 of the installation process and is identified using the -ll
argument flag when executing the driver.
Accessing Connector Configuration
The custom connector configuration file can be found in the following directory: /etc/tq_labs/
.
The custom connector configuration file was created in step 10 of the install process and identified using the -c
argument flag when executing the driver.
CRON
The addition of the --cron
argument in the initial run of connector, performed during the install process, resulted in the creation of a cron job file for the connector in the following directory: /etc/cron.d/
. The contents of the file will resemble the following structure:
The {schedule}
will be replaced with the cron settings you entered with the --cron
flag and the {executable}
will be replaced for with the connector's driver command.
You will also see a #
at the beginning of the file. This comments out the job. This allows you to configure the custom connector in the ThreatQ UI first. After you have configured the connector in ThreatQ, you can remove the #
from the file content's in order to activate the cron job.
To summarize this process:
- Install the connector and perform an initial run using the
--cron
argument to create the cron job. - Complete the connector's configuration settings in the ThreatQ UI.
- Access the connector's cron file in the
/etc/cron.d/
directory and remove the # from the beginning of the file.
Automatic CRON configuration has been removed from this script. To run this script on a recurring basis, use CRON or some other jobs scheduler. The argument in the CRON script must specify the config and log locations.
Add an entry to your Linux crontab to execute the connector at a recurring interval. Depending on how quickly you need updates, this can be run multiple times a day (no more than once an hour) or a few times a week.
In the example below, the command will execute the connector every two hours.
- Log into your ThreatQ host via a CLI terminal session.
- Enter the following command:
crontab -e
This will enable the editing of the crontab, using vi. Depending on how often you wish the cronjob to run, you will need to adjust the time to suit the environment.
- Enter the commands below:
Every 2 Hours Example
0 */2 * * * /opt/tqvenv/<environment_name>/bin/tq-conn-devo-ioc-exporter -c /etc/tq_labs/ -ll /var/log/tq_labs/ -v3 - Save and exit CRON.
Known Issues / Limitations
- Lists and IOCs submitted by the integration may take up to 10 minutes to be viewable on the Devo platform.
Clearing your browser cache and/or logging out and back in may speed up this process.
- Certificates required for configuration are only for write access to the lookup lists
