Paris, France. The Sun is shining on the city of lights and temperatures are quite high, even for the summer season. Life is good. As a matter of fact, life is excellent.
TheHive Master Cooks are about to go on vacation for a few weeks. But before they pack up their Patagonia bags and leave the sandy beaches for those who enjoy them, preferring mountains, trails, walking and breathing fresh air with family and friends, they would like to make a significant contribution to help TheHive and Cortex users fight cyberattacks even better than they already do. And maybe convince those who don’t that free, open source software is not a joke or a geek fad.
We’d like to welcome to the stage our latest babies, which we are really proud of: TheHive 3.1 and Cortex 2.1, the new versions of the power duo which make digital forensics, incident response and, to an extent, cyber threat intelligence, better, faster, happier, regular exercising (well you know the Radiohead song so we’ll let you continue singing along) since early 2017.
While our project might seem very young, it is not. We’ve been working steadily on TheHive, using it (i.e. eating our own dog food) since early 2014 before releasing it at the end of 2016 once we were satisfied with it, as a token of gratitude to a community that helped us due our jobs in various ways. We then extracted what has become Cortex from its core to ship it as a separate product in February 2017. And we kept improving them at a steady piece for the collective benefit of incident responders, forensicators and threat analysts. And adoption has been rather spectacular. Thanks to all of our users for their love and support!
We believe we are at a moment where people could not brush us off anymore as amateurs. Try TheHive and Cortex, preferably with MISP and get a taste of what professional, free and open source software can be.
TheHive 3.1 and Cortex 2.1 are feature-packed and we won’t be able to cover them all in detail in a single blog post. Rather, we’d like to concentrate on a few important ones.
Stable, Pre-release Channels and New Repositories
We’d like to point out that, in order to improve our release process and given the number of features that we added, TheHive 3.1 and Cortex 2.1 are release candidates at this stage. So we encourage you to test them and report back any bugs or issues you encounter so we can address them and make the final releases as rock-solid as possible.
We have now two release channels: a stable one that should be used for production systems and a pre-release channel that should be used to try the release candidates such as TheHive 3.1-RC1 and Cortex 2.1-RC1, the subjects of this blog post, and help us iron out bugs before adding them to the stable channel. Those who love living on the bleeding edge may be tempted by running the release candidates on their production environment given all the candy and icing we added. They are at liberty of doing so but we don’t want to hear anyone one whining about an RC that broke everything and asking for their money back grin.
We also moved our package and binary repositories to https://bintray.com/thehive-project and Docker images are now under thehiveproject.
Please check TheHive Installation and Cortex Installation guides for further details.
MISP with a Purpose
In previous releases of TheHive, whenever you configured a MISP instance, it was used to import events from and export cases to. Starting from TheHive 3.1.0, we added a
purpose to the configuration file. By default, any added MISP instance will be used for import and export (
ImportAndExport). However you can configure it to be used for importing events only (
ImportOnly) or exporting cases only (
When an analyst attempts to update a MISP event on which the account used by TheHive to connect to the MISP instance is not part of the original author’s organization, previous versions of TheHive will display a
you do not have permission to do that error produced by MISP. Starting from TheHive 3.1, analysts have the ability to create a MISP extended event.
Case tasks can now be associated with task groups. For example, you could create groups called Identification and Malware Analysis, Containment and Communication and add tasks to them. Of course, this new feature can be used when designing case templates as well.
Import Observables from Analyzer Output
If analyzers produce a set of artifacts in their output (which is the case of several existing ones), TheHive will give you the ability to select those artifacts very easily and add them to your case as observables.
ZIP File Upload
Austin Haigh contributed an important feature which will allow analysts to directly import password-protected ZIP files into a case. The code uses the supplied password when adding the archive to extract its contents and add them one by one to the existing set of observables. This is highly practical when you want to add suspicious files without risking an accidental click which would compromise your endpoint or having to unzip archives containing such files first then add them one by one to TheHive.
Revamped Search Page
The search page has been completely revamped as shown in the screenshot below:
You can now select your search scope (cases, tasks, observables, alerts, analyser reports a.k.a. jobs or even the audit logs), apply filters and search TheHive without having to resort to complex, mind numbing Lucene syntax.
Responders and PAP
Last but not least, TheHive and Cortex offer you response capabilities (i.e. perform an action depending on the context) thanks to a new breed of programs called … wait for it … wait for it … responders. TADA!
Responders are very similar to analyzers. In fact we’ve taken the concept and extended it to apply to different elements in TheHive: alerts, cases, tasks, task logs, and observables of course.
You can reuse almost the same principles that apply to analyzers to write your own responders and if you are feeling generous, contribute them to the community. To give you a head start, we published a sample Mailer responder which, when customized for your environment, should allow you to send emails to inform your fellow analysts that a case has been created and that their help is required. Another example could be the ability to respond to a suspicious email report from a user, which is displayed as an alert, that they can safely ignore the corresponding email.
Like an analyzer, a responder can have two or more service interaction files (or flavors) to allow it to perform different actions. For example, a Mailer responder can send messages using several body templates.
Thanks to our long-time friend Andras Iklody from MISP Project who brought that to our attention, responders (and analyzers starting from Cortex 2.1) support PAP, the Permissible Actions Protocol.
