Cortex-Analyzers 1.10.2

On June 6, 2018, we released Cortex-Analyzers 1.10, which contained 11 new analyzers, bringing the total to 83 programs. You read that correctly: 83 ways to assess and gain insight on observables collected during the course of an investigation or while performing threat intelligence thanks to Cortex, our free & open source analysis engine. One day after, we published version 1.10.1 which fixed the name of the Anomali STAXX reports for TheHive. Since then we uncovered a few additional issues which version 1.10.2 corrects:

  • #273 & #283: two encoding issues in the ThreatCrowd JSON definition file
  • #275: the GreyNoise mini-report for TheHive did not produce any information when no record was found
  • #278: the IBM X-Force analyzer forced the TLP in its configuration
  • #279: the VMRay should authorize self-signed certificates
  • #280: the name of the IBM X-Force Exchange report folder was incorrect preventing TheHive from displaying mini-reports or usefully laid out long ones

To install this hotfix release on your Cortex instance:

$ cd /path/to/Cortex-Analyzers
$ sudo git pull

Then log in to the Cortex Web UI as an orgAdmin and click on Refresh Analyzers:


If you are using TheHive, make sure to download the latest version of the report templates and import them into your instance.

VMRay, FireHOL, Joe Sandbox & Fortiguard Analyzers

We are pleased to announce the availability of 2 new Cortex analyzers and an update to 2 existing ones:

  • New: VMRay and FireHOL
  • Updated: Joe Sandbox and Fortiguard URL Category

We would like to thank Nils Kuhnert from CERT-BUND, CERT-BDF and Eric Capuano for their precious contributions.

To install the new analyzers, grab the Cortex-Analyzers repository and unpack its content (or git pull the master  branch) in your existing /path/to/cortex-analyzers. Then follow the Cortex analyzers guide.

To import the new report templates in your instance of TheHive:

  • download the updated package
  • log in TheHive using an administrator account
  • go to Admin > Report templates menu
  • click on Import templates button and select the downloaded package


The VMRay analyzer has been submitted by Nils Kunhert from CERT-BUND. It lets you run a file in a local or remote (cloud) VMRay sandbox. The analyzer also lets you check existing analysis reports.

The analyzer accepts files and hashes as input. VMRay is a commercial service and you need an API key to run the analyzer. To make it work, install the requests Python library. It should already have been installed since it is used by other analyzers as well.

To use the analyzer, add the following section to the Cortex configuration file (application.conf):

VMRay {
 url = ""
 key = ""
 certpath = ""

When called from TheHive, the following output is produced:


TheHive: VMRay Analyzer – Short and Long Report Samples

Important note: an analysis on VMRay, like on any other sandbox, can take a long time. That is why the analyzer tries to fetch the report until it is ready.


The FireHOL analyzer has been submitted by Nils Kuhnert from CERT-BUND. It lets you use the lists maintained by FireHOL project and check if an IP resides in one of them. FireHOL is an open source project. The analyzer reports the block lists in which an IP resides with the latest updated ones displayed first. To make it work, you’ll need to download the lists in a directory first (and it would be wise to do it on a regular fashion using a cron entry for example):

git clone

The FireHOL analyzer depends on the following librairies:


Add the following section to the Cortex configuration file (application.conf) to activate the analyzer:

FireHOLBlocklists {
 blocklistpath = ""
 ignoreolderthandays = <int>

The ignoreolderthandays parameter lets you tell the analyzer to ignore matches found in lists that have not been refreshed in <int> days where <int> is an integer.

When called from TheHive, the following output is produced:



TheHive: FireHOL Analyzer – Short and Long Report Samples

Joe Sandbox

Thanks to CERT-BDF, the Joe Sandbox analyzer has been updated to support Joe Sandbox Cloud service beside the on-premises version (Ultimate). Like with other Joe Sandbox services, you need to add the following section to the Cortex configuration file (application.conf):

JoeSandbox {
 url = ""
 apikey = ""

Fortiguard URL Category

Thanks to Eric Capuano, the Fortiguard URL Category analyzer is working again. Eric has modified it to handle the changes made by Fortiguard to their free online API.

Correction: May 23, 2017
An earlier version of this post used ignoredays instead of ignoreolderthandays for the FireHOL Blocklists analyzer. This parameter has also been described.
