The Dockerization Will not be Televised

Do you know what the following set of commands achieve?

$ cd /opt/Cortex-Analyzers
$ sudo git pull
$ for I in $(find /opt/Cortex-Analyzers -name 'requirements.txt'); do sudo -H pip2 install -U -r $I; done \
&& for I in $(find /opt/Cortex-Analyzers -name 'requirements.txt'); do sudo -H pip3 install -U \
-r $I || true; done

The answer is obvious Doctor Watson, right? These highly readable commands (pun intended) allow you to update your Cortex analyzers and responders to the latest stable versions, downloading new ones in the process, going over all the Python 2 and Python 3 dependencies to install the missing ones and upgrade the old ones to make sure they work correctly. These operations take quite a long time and cause some headaches in the process (Hello, I have Python 3.X and this dependency is no longer required, or Hi, I have an old version of Python 2 and it seems I need this other dependency).

And if you are lucky enough to get it running smoothly, you are still not done as you need to log in to the Cortex UI as an organisation administrator (unlike TheHive, Cortex supports multi-tenancy), click on the Refresh analyzers button under Organization > Analyzers then go to Organization > Responders and click on Refresh responders.

So while the answer to the opening question might be simple, updating analyzers and responders is far from being straightforward, to say the least, even if we forget the ugly fact that both are stored in a repository “conveniently” named Cortex-Analyzers*:

thehive@thehive-training:/opt/Cortex-Analyzers$ ls -d a* r*

Unnecessary Complexity Must Die

Your lovely, hard-working bees hate unnecessary complexity. Our project’s front page blatantly states our mission to bring Security Incident Response to the masses. And we have to stand by our words even if TheHive and Cortex are free, open source solutions and we do not gain anything from them save for the huge satisfaction of helping our fellow incident handlers level the fight against cybercriminals & all kinds of other animals of the APT (Advanced Persistent Troll Threat) bestiary.

There is only one possible solution: simplify the installation and update process of the current, official 115 analyzers and responders we have as of this writing, the future ones and any private or unofficial ones written in other programming languages such as those developed in Go by Rosetelecom-CERT.

Docker all the Things!

Starting from Cortex 3.0, the next major release of your favourite analysis and active response engine, all analyzers and responders will be dockerized. It will no longer be necessary to install them along with their various dependencies. They will be dowloaded from our cortexengine Docker organisation. Sysadmins might also configure automatic updates.

As a side advantage of using Docker, analyzers, and responders will also be isolated from each other which gives more flexibility and possibilities.

For those users who have private, custom analyzers and responders that they don’t want or can’t share with the community, several options will be available:

  • Continue managing their analyzers and responders in the same way as currently supported by Cortex 2 (i.e. launch them as processes, with no isolation whatsoever).
  • Dockerize them and store them locally on their Cortex instance.
  • Dockerize them and publish them on a Docker registry, either the official one or a private registry.

A Docker image of Cortex 3 will still be provided. It will contain a Docker engine to launch dockerized analyzers and responders using DIND (Docker in Docker).

It won’t be necessary to modify the code of the current, official analyzers and responders. A drone job will monitor the analyzer and responder repository and automatically build docker images when it detects changes.

The Cortex Web interface will be slightly modified to accommodate the whole process and allow adding in-house/private Certificate Authorities to allow Cortex to smoothly perform updates in those corporate environments where TLS/SSL inspection is enabled.

Nice Movie Trailer. When is it Coming to a Theatre near me?

We are working hard to get Cortex 3 out of the oven in Q1 (of this year, yes). We will reach out to you, dear reader, in due time, to help us test it and refine it before putting it on the digital shelf for free, as usual. We will provide a smooth migration path in order to move safely your current analyzers and responders and their configuration to Cortex 3.

So to paraphrase the late and great Gil Scott-Heron:

The dockerization will not be televised

The dockerization will not be televised

The dockerization will be live.

Since you are here

The success of TheHive and Cortex continue to grow, far more than we initially foresaw. As far as we know, there are about a hundred organisations of different sizes and locations using or testing them. And as the number of users grows, so does the number of features, professional service and support requests.

We have tried addressing these requests through Creative Source, a nonprofit organisation (NPO). All but one company trusted us enough to make a donation and get tailored services for its needs in return. Most of the others either did not reply to our proposals or explained that their procurement process does not accommodate working with NPOs.

Some members of our core team are actively working on alternative options to ensure not only the viability of TheHive and Cortex as FOSS products on the long run but the ability to provide professional training, support, and services without freaking out highly bureaucratic, think-in-the-box-but-never-outside procurement departments.

Stay tuned 🐝


(*) When the idea behind Cortex was born into our hive mind, we did not initially think about active response capabilities. So we naturally called the repository which was supposed to contain analyzers Cortex-Analyzers . When, at a later stage, we added responders, we put them in the same repository for obvious laziness pretences  ¯\_(ツ)_/¯.

Cortex 2.1.3: Security and Beyond

TheHive Project’s code Chefs are happy to announce the immediate availability of Cortex 2.1.3, a hotfix for your favorite observable and response engine, fresh out of the oven!

We highly recommend that you upgrade your existing installation to this new version as soon as feasible as it plugs a significant security vulnerability, kindly reported by Po-Hsing Wu. The vulnerability is a privilege escalation one which allows an orgadmin to create a superadmin user. The culprit has been punished by having to chant Perl mantras while doing a handstand on burning coals.

Additionally, Cortex 2.1.3 fixes the following bugs:

  • #157: list and disable invalid responders
  • #152: enforce PAP when launching an analyzer from the Cortex Web UI
  • #147: add dig to the Cortex docker image as the SinkDB analyzer needs it
  • #146: the Cortex job list must display the PAP value
  • #145: fix the broken Web UI’s search function for job history

Pardon my French but do you speak English?

  • PhishingInitiative analyzer has been flavoured with a scan facility, thanks to Rémi Pointel

Huge thanks for the awesome work that has been performed by all our contributors!

Hunterio_DomainSearch

Hunter.io is a search engine that lets you find emails associated with a given domain name. The analyzer can be used to query the API and get a list of email addresses for a specific domain name. An API key is required to use this analyzer and can be obtained by registering on the website.

Results are displayed in TheHive in the following manner:

sc-hunterio-short

sc-hunterio-long
Hunterio_DomainSearch: short and long report samples

DShield_lookup

The analyzer lets you query the famous SANS Internet Storm Center (ISC) DShield API and look up IP address reputation. No API key is needed to run this analyzer.

Results are displayed in TheHive in the following manner:

sc-dshield-short

sc-dshield-long
DShield_lookup: short and long report templates

Pulsedive_GetIndicator

Pulsedive is a Threat Intelligence platform that allows you to enrich your observables. The analyzer can be used to query  the API and get information about a domain name,  hash, IP or URL. An API key is required to use this analyzer and can be acquired by creating an account on the webiste.

Results are displayed in TheHive in the following manner:

sc-pulsedive-short

sc-pulsedive-long
Pulsedive_GetIndicator: short and long report templates

Manalyze joins FileInfo

Manalyze is a tool developed by Ivan Kwiatkowski (@JusticeRage) that lets you analyze, operate PE (Portable Executable) and collect useful artifacts that help the analyst in determining its maliciousness.

@lctrcl wrote an analyzer that triggers Manalyze on a PE file and gives the analyst a useful report. Nils Kuhnert (@3c7) from TheHive Project then included this analyzer as a submodule into our FileInfo meta-analyzer for files ; it can run Manalyze from compiled binary, or, if your Cortex server is ready for that, through the right docker. If you decide to use the compiled binary, please follow instruction from Manalyze github page.

This submodule is disabled by default. To use it, you have to set some configuration in Cortex:

sc-fileinfo-config
FileInfo: configuration for Manalyze in Cortex

Results are displayed in TheHive in the following manner:

sc-fileinfo-short3

sc-fileinfo-long3
Manalyze submodule: short and long report templates

Fortiguard_URLCategory

This analyzer has been enhanced to let analysts choose categories considered as malicious or suspicious. It comes with a default configuration but you can setup your own by selecting the categories from the Fortiguard website.

sc-fortiguard-config
Fortiguard_URLCategory: default configuration for categories  in Cortex

Select which categories you want to be considered malicious or suspicious, and others will be considered by the analyzer as info. Analyzed observables that are not categorised by Fortigard service is considered as safe.

PhishingInitiative_Scan

PhishingInitiative has been enhanced with a new scan flavor. This let the analyst submit an URL to the webservice. An API key is needed to run this analyzer and can be obtained by registering on the website.

Results are displayed in TheHive in the following manner:

sc-phishinginitiative-short

sc-phishinginitiative-long
PhishingInitiative_Scan: short and long report samples

Bug fixes

  • #335 : fix a bug in MISP analyzer
  • #340 : fix short report template in C1fApp
  • #339 : fix short and mini reports for Domaintools Whois history flavor

Get It While Supply Lasts!

Each analyzer comes with its own, pip compatible requirements.txt file. To update your Cortex analyzers to 1.13.0, run the following commands:

cd path/to/Cortex-Analyzers
git pull
for I in analyzers//requirements.txt; do sudo -H pip2 install -r $I; done && \
for I in analyzers/
/requirements.txt; do sudo -H pip3 install -r $I || true; done

Once done, do not forget to login to Cortex as an orgadmin and click on the Refresh Analyzers button. Refer to the online Cortex documentation for further details.

Update TheHive Report Templates

If you are using TheHive, get the latest version of  the report templates and import them into TheHive.

Mellifera Is Here

TheHive Project French chefs are very excited to announce the immediate availability of Mellifera, TheHive 2.11.0, the greatest and latest iteration of our flagship product.

We are thrilled to share this major version with the incident response community, for free as usual. Yes, you read that sentence right. You don’t have to cough up a single € or BTC for a platform that is as good as some commercial alternatives, unless your boss is hassling you about paying big bucks to get so-called professional support. If that’s the case, try us and you might prove them wrong.

Going through all the features and fixes of this significant overhaul will take forever (well, almost) so let us highlight a few that we feel worthy of your attention and time.

The Alerting Framework

If you need one reason to upgrade from Buckfast to Mellifera or to ditch your existing, clunky incident handling platform and use ours, then that should be its brand-new and powerful alerting framework.

With Buckfast (TheHive 2.10.x) and earlier versions, you can configure multiple MISP instances. TheHive will then poll those instances at regular intervals and display new or updated events in a specific area where analysts can preview them, import them as cases using configurable templates or ignore them altogether (and if they do so by mistake, there’s no way to go back). And if you needed to raise alerts from a SIEM, email reports or other sources of noteworthy security events, you had to rely on TheHive4py API client and create a case without having a chance to preview the events in TheHive prior to the case creation.

Mellifera does not have these limitations. It features an all new, fancy and efficient alerting framework which can be displayed using the Alerts button in the Web interface. This button was previously called MISP.

Within the Alerts area, you can preview not only new or updated MISP events but also any event that you have pushed through TheHive4py. The client has been modified to be compatible with Mellifera. If you have an existing TheHive4py package, please upgrade to the new 1.2.0 version using PIP.

The New Alerting Panel

Using TheHive4py 1.2.0, you can send your SIEM alerts, user email reports and security events from various sources to Mellifera and your analysts will be able to preview and import them or simply ignore them. If they have ignored some events by mistake, they can use the quick actions on the top of the panel to retrieve them. Please note that you have to create programs that will bridge your event sources with Mellifera through TheHive4py.

All New Skin

Mellifera has an all new skin with many refinements spread all over the interface. For example, you can now easily reorder the tasks within a case template. You can also sort task logs according to their creation date (oldest first, newest first). The flow (a.k.a live stream) is also collapsible. Moreover, when you create a case, Mellifera will suggest existing tags.

Mellifera’s Brand New Skin

Is MISP or Cortex There?

If you have configured Mellifera to interact with at least one MISP or Cortex instance, the Web interface will show their respective logos at the bottom of the page. Please note that you can now connect to MISP and Cortex even if you are behind a proxy which requires authentication.

New Installation Packages

Starting from this release, we no longer produce all-in-one binary packages and dockers containing TheHive and Cortex. Instead you can use dockers, binaries and RPM as well as DEB packages. Wink wink.

One More Thing

Mellifera has an all new logo and the project website has been completely redesigned. Now you can see who’s behind the project thanks to Alexandre Gohier, a close friend who also happens to be a professional photographer.

Download & Try

If you have an existing TheHive installation, please follow the new migration guide.
