Thehive5 Webhooks

When it comes to online applications some of the best functionality comes when you can programmatically tap into it as it creates countless opportunities to customise and extend the functionality to suit your needs without having to modify the underlying application. In the Context of TheHive, the API will allow you to query, post or search data which can aid in the lifecycle of an incident as well as create alerts and cases programmatically.

Docker Config: Thehive5 with Cortex and n8n

I’ll start by saying, that I have done these sorts of posts in the past where I have stood up TheHive and reverse proxies etc using a docker-compose file so the basic configuration etc is going to be heavily borrowed except for some minor tweaks. I am still old school so this isnt a configuration you would want to run for mission critical services, however there is a guide for how to use Docker in Production.

TheHive 5

TheHive. You know i’m a huge fan of this Incident Response platform with many blog posts dedicated to it including how you can integrate and interface with it. Over the years TheHive has been on a journey and has matured and stabalised. Now with a new code base the developers have taken full control of the licensing for version 5. I do however have mixed feelings about this. On one hand i’m sad that TheHive no longer open source.

Upgrading Cortex 3.0.1/ES5.6 to Cortex 3.1.0RC1/ES7.8

In my last post, I covered how I went about upgrading TheHive from 3.4 to 3.5RC1 along with a double upgrade of Elasticsearch. Well now its Cortex’s time. Cortex 3.1.0 also uses Elasticsearch 7.8 so we are in for a similar upgrade process. Depending on your reliance on Cortex it may be a nice addition to TheHive that is rarely used, or it may be critical to your operation. Either way, getting to the latest version is desirable as there are always welcome bug fixes and improvements with error handling, reporting and general integration.

Upgrading TheHive 3.4.0-1/ES5.6 to TheHive 3.5.0-RC1/ES7.8

TheHive 3.5.0 RC1 has now been released and my environment is in a bit of a shambles for this upgrade. You see when I performed my upgrade of TheHive 3.2.1 to 3.4.0 I elected to not upgrade to ElasticSearch 6.8 at the time as I wanted to do some more testing on it. I told myself, TheHive 3.4 was working just fine using Elasticsearch 5.6, so I never went ahead with the Elastic part of the upgrade.

Data Migration from TheHive3 to Thehive4

Well its been a few months since I have written anything on my blog. Its not that I’ve been lazy, well OK its because I’ve been a little lazy and that I have been chasing squirrels and playing around with Home-Assistant and other various pieces since being in lockdown. I have also lacked the motivation to get something down in writing. Anyway, on with what I wanted to write about….

Thehive4 RC1 to RC2 Upgrade

With my Java issue sorted out now, here are the steps to upgrade TheHive from RC1 to RC2. This is a dirty upgrade, but since TheHive is still in Release Candidate status, we can get away with upgrading like this. Ordinarily you should ensure that you have your system backed up in case there are breaking changes. Stop TheHive service sudo service thehive stop Update apt repositories and upgrade May as well apply all the security updates while I am at it.

TheHive 4.0.0-RC2: Last error: Connection refused

I was so excited at the thought of all the cool new features that have popped up in TheHive v4.0.0-RC2 that I went straight onto my lab to give it a spin. Little did I know that my system was broken before I even started and I spent the best part of a few hours trying to figure out what exactly happened. For a brief moment I did consider burning the lab down and just rebuilding it, but I asked myself what would happen if this were a prod system?

TheHive in Docker

Docker is something that i’ve not fully embraced to date, I know, I know… I’m a little late off the mark, but as I get to know Docker more, I can see that it has some worthwhile advantages for me in some of the projects I use and generally getting to know technology is never a bad thing. For instance, why spin up a single server for a service that only has 1 of the 65535 ports used when 99% of the time that server will most likely be idle.

Adding Traefik Reverse Proxy to Opencti

Well this one was a bit of a learning experience for me. You see I have dabbled in the past with Traefik which seems to fit naturally when it comes to reverse proxy and Docker, but my efforts have come up short in the past through no fault but my own. Perhaps it was the fact I was trying to run before I could even crawl. Not to worry though.

Adding MISP to OpenCTI

While im still getting myself familiar with OpenCTI and building out an actor profile, I thought I’d link it up with my MISP instance. OpenCTI provides a connector to do this which will require an update to the docker-compose.yml file and an update of the stack. If you have been following along, this post is a continuation of Installing OpenCTI. To add the MISP connector, login to Portainer and select Stacks, opencti.

OpenCTI Installation

OpenCTI is an open source Cyber Threat Intelligence platform that provides a powerful knowledge management database for storing, organising and sharing knowledge about cyber threats and uses the STIX2 schema for it structure. It has been designed for CTI analysts. The platform is built on Modern technologies of Grakn, GraphQL, Elastic, RabbitMQ, Redis and React. The project is available as a docker image which make installation simple. While I’m probably not going to do the best job of talking up the full feature set of this platform, you can view more about it on their website and github page.
