Cortex-Analyzers 2.7.0: 5 Analyzers, 1 Responder

Good morning (or evening if you are on that side of the planet) folks!

We had a very busy week, packed with announcements. First, we released TheHive 4.0-RC2 which you’ve certainly taken to test, then we announced two patch releases for TheHive 3.4. And guess what? Here are some additional Cortex analyzers, a responder and a number of fixes and improvements for existing ones, bringing the total to a whopping 146 analyzers and 18 responders!

New Analyzers

New Responders

Analyzers

ANY.RUN

ANY.RUN is a malware sandbox service in the cloud. By using this analyzer, an analyst can submit a suspicious file or URL to the service for analysis and get a report. The report can contain various information such as:

  • Interactive access
  • Research threats by filter in public submissions
  • File and URL dynamic analysis
  • Mitre ATT&CK mapping
  • Detailed malware reports
ANY.RUN short report
ANY.RUN long report

CyberChef

CyberChef is a simple, intuitive web app for carrying out all manner of “cyber” operations within a web browser. These operations include simple encoding like XOR or Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more.

This analyzer connects to a CyberChef-server and comes in 3 flavors:

  • CyberChef_FromBase64, that takes Base64 strings as input for CyberChef-server
  • CyberChef_FromCharCode, that takes CharCode as input for CyberChef-server and run this recipe
  • CyberChef_FromHex, that takes Hex strings as input for CyberChef-server

TheHive displays the analyzer results as follows:

CyberChef short report
image
CyberChef long report

MalwareBazaar

MalwareBazaar is a project from abuse.ch with the goal of sharing malware samples with the infosec community, AV vendors and threat intelligence providers.

This analyzer allows analysts to query the API of this service on observables of types ip, domain, fqdn, url, and hash.

TheHive displays the analyzer results as follows:

MalwareBazaar short report
MalwareBazaar long report

OpenCTI

OpenCTI is an open source platform allowing organisations to manage their Cyber Threat Intelligence knowledge and observables. It has been created in order to structure, store, organise and visualise technical and non-technical information about cyber threats.

This analyzer allows an analyst to query the API and request for information about observables of types domain, ip, url, fqdn, uri_path, user-agent, hash, email, mail, mail_subject, registry, regexp, filename and other.

TheHive displays the analyzer results as follows:

OpenCTI short report
OpenCTI long report

MISPWarningLists reloaded (need for speed aka DB support)

The previous version of this analyzer basically used to clone the MISP Warning lists repository and do a lookup in downloaded files. This can be very long to complete.

This new version introduces the optional support of PostgreSQL:

  • To store warning lists, in a similar way to the NSRL (National Software Reference Library) Analyzer.
  • Make lookups through these lists faster.

If you want to benefit from the performance boost, using a PostgreSQL server to store the data, you can simply install the requirements.txt, feed the database and configure the connection in the configuration as well:

  • First, sync with the misp-warninglists GitHub repository
  • In the analyzer folder, use the program warninglists_create_db.py to import the warning lists in PostgreSQL. Before running, edit the program file and update the path of where your lists are stored (warninglists_path = "misp-warninglists/**/list.json")
  • You can schedule these jobs (ex. with cron): first, sync a folder with the repository, and then run the program to update the database.

Once done, configure the analyzer with the conn parameter to connect to the database, or, if you prefer to continue using the previous behaviour and do your lookups in files, just specify the path of the folder:

MISPWarningList Configuration example

Templates have also been updated, and TheHive displays the analyzer results as follows:

MISPWarningList short report
MISPWarningList long report

Responders

RT4-CreateTicket

RT4 (Request Tracker) is a ticketing system. With this responder, an analyst can create a ticket in RT. CaseID is submitted to RT as a reference.

Unfortunately, like for some other analyzers and responders, we have not been able to test this responder on our side. Please feel free to share your feedback with us and also with Michael Davis, who we would like to thank for the hard work and for having shared this responder with the community.

Fixes and Improvements

  • Fix Inconsistent Key References in Shodan Analyzer (#748)
  • Fix SSL & python3 for Yeti Analyzer (#468 , #708)
  • Fix bug in Emlparser Analyzer (#730)
  • Fix in Shodan Analyzer: Inconsistent Key References (#748)
  • Support python3 in DNSDB Analyzer (#613)

Cortex-Analyzers 2.6.0: 146 Analyzers, 18 Responders

Amidst the ongoing COVID-19 crisis, we managed to release Cortex-Analyzers 2.6.0, which includes 4 new Analyzers, 2 new Responders, and a large number of bug fixes and improvements.

We’d like to thank all the contributors for their awesome work!

We truly appreciate the time they generously give away for helping our fellow cyberdefenders out there protect their environments against attackers who are also in lockdown mode. Attackers who, instead of playing board games or chess, are playing with our nerves and the hordes of teleworkers who are willing to click on anything that provide the ‘latest and greatest COVID-19 information’ or which can help them do their jobs (like this wonderful ‘Zoon’ video-conferencing application 😋).

What’s New?

New Analyzers

New Responders

Analyzers

DomainTools Iris

The Investigate flavour was missing from the DomainToolsIris analyzer that was included in Cortex-Analyzers 2.4.0. This is now fixed. This new flavour can be used to gather interesting information on a domain.

TheHive displays the analyzer results as follows:

DomainToolsIris_Investigate short reports
DomainToolsIris_Investigate long report

IntezerCommunity

Intezer Analyze™ is a cloud-based malware analysis service that provides an extensive understanding of any executable file by comparing code on a massive scale to a comprehensive database of malware and trusted software. 

This analyzer can be used to submit a file to the Intezer service for analysis.

TheHive displays the analyzer results as follows:

IntezerCommunity short report
IntezerCommunity long report

NSRL

The National Software Reference Library (NSRL) is designed to collect software from various sources and incorporate file profiles computed from this software into a Reference Data Set (RDS) of information. The RDS can be used by law enforcement, government, and industry organisations to review files on a computer by matching file profiles in the RDS. This will help alleviate much of the effort involved in determining which files are important as evidence on computers or file systems that have been seized as part of criminal investigations.

In order to use this analyzer, you must download and extract NSRLFile files from the NIST website. You can pick multiple files but you need to rename them in order to understand which file contains the required information.

All files are called NSRLFile.txt, renaming them permit to understand in which file the record has been found.

The analyzer can operate in 2 different ways with 2 completely different performance profiles (we’re speaking around 30 secs vs 0.05 sec):

  1. lookup in plain files
  2. lookup in a database

If you are planning to use this analyzer for many searches, then the second option is suggested and we provide a script to help you parse, validate and insert data in a PostgreSQL database. If you choose this option, consider that the DB size can be around 4 times bigger than plain files.

NSRL Lookup short template
NSRL Lookup long report

UrlScan.io

The URLScan.io analyzer has been updated with a new Scan flavour. Until now, this analyzer allowed to request report regarding a url, domain, fqdn observable. With this new flavour, anyone with a valid API key, which can be obtained for free, can request a scan on observables of the same type.

UrlScan.io short template
UrlScan.io long template

Responders

DomainToolsIris_CheckMaliciousTags

Depending on the reports generated by the DomainToolsIris analyzer, this responder adds a tag at the Case and Observable level if something malicious is found. This responder can be updated to add more custom actions depending on your needs and environment.

DomainToolsIris_AddRiskyDNSTag

Depending on on the reports generated by the DomainToolsIris analyzer, this responder adds a tag at the Case and Observable level if one of the domain observables is considered risky. This responder can be updated to add more custom actions depending on your needs and environment.

Fixes and Improvements

  • Improve TalosReputation analyzer (#521)
  • MISP WarningList analyzer fixed (#538)
  • Error fixed in ThreatCrowd (#518)
  • Encoding related bug fixed in Mailer 1_0 (#573)

Clamav is a powerful and open source antivirus engine that allows writing custom signatures using Yara and sigtool. @Hestat contributed with this analyzer that permits to TheHive to communicate with a local clamav-daemon.

A detailed configuration guide is available on Hetstat’s website.

Clamav short report for safe and malicious samples

IPVoid

Contributed by @jdsnape, this analyzer leverages the IP reputation check of apivoid.com, the API of www.ipvoid.com. As you can probably guess by its name, this analyzer can be used to enrich ip observables.

In order to use this analyzer, an account and a valid subscription to apivoid.com are required. An API key needs then to be provided.

TheHive displays the analyzer results as follows:

IPVoid analyzer short report
IPVoid analyzer long report

ThreatResponse

This analyzer lets you leverage the Cisco Threat Response service. Query Threat Response for verdicts and sightings for observables of type domain, filename, fqdn, hash (MD5, SHA1, SHA256), ip and url.

The analyser report lets you pivot into a Threat Response investigation of an observable.

Combining it with AMP for Endpoints Responder

It will extract the connector GUIDs as new observables to enable seamless use of the AMP for Endpoints Responder if a target is returned from the AMP for Endpoints module. It requires the AMP for Endpoints module to be configured in Threat Response.

A valid Cisco ThreatResponse subscription is required, and you have to provide your client ID and password information to use this analyzer.

TheHive displays the analyzer results as follows:

ThreatResponse analyzer short report
ThreatResponser analyzer long report

ThreatGrid

This analyzer queries Cisco Threat Grid for file, url, or hash and deliver analysis report. It also lets you pivot into the Threat Grid report to access more information related to Behavioral indicators or TCP/IP stream.

A valid Cisco Threat Grid subscription is required, and you have to provide hostname and api key to use this analyzer.

TheHive displays the analyzer results as follows:

ThreatGrid analyzer short report

AMPForEndpoints

This responders performs several actions on Cisco AMP for Endpoints. It comes in 5 flavors:

  • AMPforEndpoints_IsolationStart: Start Host Isolation.
  • AMPforEndpoints_IsolationStop: Stop Host Isolation.
  • AMPforEndpoints_MoveGUID: Move Connector GUID to a new group.
  • AMPforEndpoints_SCDAdd: Add SHA256 to a Simple Custom Detection List. TheHive’s case ID and description are appended to the description
  • AMPforEndpoints_SCDRemove: Remove SHA256 from a Simple Custom Detetion List.

A valid Cisco AMP for Endpoints subscription is required, and you have to provide the client id, api key and several context information to use this responder.

Redmine

Redmine is a free and open source, web-based project management and issue tracking tool. It allows users to manage multiple projects and associated subprojects. 

This responder, contribuited by srilumpa, can be used to create an issue in the Redmine ticketing system from a case. It will use the case title as the issue subject and the case description as the issue body.

To set it up in Cortex, you will need:

  • To define a user to allow Cortex to connect to Redmine and with access to the various projects in which issues should be created
  • Define three custom fields in TheHive that will be used to select the project, the tracker and, optionally, the assignee of the issue. These fields can be free form or can be custom fields with preset values.
Custom fields in TheHive for Redmine integration

At the moment the responder has few capabilities. If you need any other integration feel free to discuss on the pull issue.

Mum, Docker Docks Don’t Dock Well!

Soon after we released Cortex-Analyzers 2.4.0, Jérôme noticed that something was definitely wrong. And that something was plural.

As he set to retest a few things here and there, he realised that many docker images, for the latest and greatest analyzers and responders, were not automatically built. The code factory wasn’t working 😰

Source: https://www.flickr.com/photos/8021817@N07/6262431675

So he started digging. And the more he dug, the more bugs he discovered. Our user community also reported a few issues. He thought it was about time he opens that bottle of Aloxe-Corton, put a Makaya McCraven album to play on his turntable, and rolls his sleeves to address all these problems headfirst 🍷

After a few hours of intense work, he managed to fix the docker build process and release Cortex-Analyzers 2.4.1, a hotfix that corrects the following issues:

  • [#545] Message extraction using FileInfo doesn’t always work
  • [#610] The VirusTotal analyzer contains a typo which prevents it from running
  • [#614] Many analyzers fail to run due to incorrect permissions
  • [#619] Abuse Finder not working with docker after force usage of python3
  • [#620] Missing library prevented the build of the docker image corresponding to the new MalwareClustering analyzer

Finally, he took the opportunity to rename Palo Alto AUTOFOCUS analyzers to Autofocus, for consistency purposes.

Please refer to our previous blog post, pertaining to Cortex-Analyzers 2.4.0, for update instructions.

Thank you in advance for your understanding and happy cyberfighting! 💪🏼

Cortex-Analyzers 2.4.0: 138 Ways to Analyze, 10 Methods to Respond

Guess what? TheHive Project is still alive and well, as Saâd already mentioned in a previous blog post.

We’ve been certainly very busy lately, preparing the upcoming release of TheHive 4 and doing many other things beside working on our FOSS project. As a result, it took us a rather long time to merge several community contributions and reduce the sizeable pile of pull requests.

We would like to thank our contributors for their patience and we hope the cyberdefenders out there will enjoy the brand new Cortex-Analyzers 2.4.0 release, with many new analyzers, responders and some bug fixes & improvements, bringing the total to a whooping 138 analyzers (counting all flavors) and 10 responders!

Additionally, with this release, all analyzers are now using Python 3. No more Python 2 technodebt!

This analyzer accesses IP-centric features provided by ipinfo.io. While the EmailRep API can be used without a token for limited usage, the ipinfo.io analyzer requires the configuration of an API token before use.

Maltiverse

This analyzer lets you query the free Maltiverse Threat Intelligence platform for enrichment information about a particular hash, domain, ip or url.

TheHive displays the analyzer results as follows:

Maltiverse short report
Maltiverse long report

MalwareClustering

Andrea Garavaglia contributed this one a long time ago and we finally merged it into the Cortex-Analyzers repository. Andrea gave a talk about the background of this analyzer at the fourth MISP summit. You can watch it here.

In order to use the analyzer, you need to point it to a Neo4j server (you need to supply the host, port, login & password).

PaloAlto Autofocus

This analyzer lets you leverage PaloAlto Autofocus services. Provided you are an Autofocus customer and you have access to their API, you need to configure the analyzer with your username and a token key.

The analyzer comes with 3 flavors:

  • AUTOFOCUS_GetSampleAnalysis lets you request a full report for a given hash.
  • AUTOFOCUS_SearchIOC lets you research for samples linked to specific IoCs with datatypes like domain, fqdn, user-agent, imphash, ip, mutex, tag and url. Please note that mutex and tag are not default datatypes in TheHive. You need to create them in TheHive before you can leverage them.
  • AUTOFOCUS_SearchJSON lets you research for samples based on a complex JSON query.

Important: TheHive has no templates corresponding to this analyzer have been published yet. They will be provided in the near future.

SpamhausDBL

This analyzer performs reputation lookups of a domain or a fqdn against Spamhaus Domain Block List (DBL).

TheHive displays the analyzer results as follows:

SpamhausDBL short report
SpamhausDBL long report

TeamCymruMHR

This analyzer queries Team Cymru’s Malware Hash Registry for known malware hashes (MD5 or SHA-1). If it is malware and known by the service, it returns the last time it has been seen along with an approximate anti-virus detection percentage.

Overview of the New Responders

KnowBe4

This responder allows the integration between TheHive/Cortex and KnowBe4’s User Events API.
If a mail observable is tagged with a specified tag, corresponding to the responder’s configuration (e.g. phished), then the associated user will have a custom event added to their profile in KnowBe4.

A valid account on KnowBe4 and an API key are required to run this responder.

Minemeld

This responder sends observables you select to a Palo Alto Minemeld instance.

To run this responder, a MineMeld Threat Intelligence Sharing account is needed.

Wazuh

This responder performs actions on Wazuh, the open source security monitoring platform. It currently supports ad-hoc firewall blocking of ip observables.

Improvements

New PassiveTotal flavors

Thanks to Brandon Dixon, the PassiveTotal analyzer gains 3 new flavors, bringing the total to 11:

  • PassiveTotal_Trackers let you make tracker lookups on observables of type domain, fqdn and ip.
  • PassiveTotal_Host_Pairs let you make host pair lookups on observables of type domain, fqdn and ip.
  • PassiveTotal_Components lets you make components lookup on observables of type domain, fqdn and ip.

They come with their own report templates.

GreyNoise Analyzer

The analyzer has been updated to support GreyNoise API v2, thanks to the contribution of Whitney Champion (#562).

New Data Types Supported by Some Analyzers

  • VirusTotal_GetReporthas been updated to allow requests for observables of type fqdn.
  • Threatcrowd has been updated to allow requests for observables of type domain.
  • Shodan has been updated to allow requests for observables of type fqdn.

Fixes

  • [#602] The MISP analyzer was bumped to version 2.1 and is ready to use PyMISP 2.4.120.

Under the Mighty Hood of TheHive 4

We have been speaking about it for almost two years. We have been making it for more than twelve months. And the day (or rather the month in this case) has almost come for TheHive 4, our latest and greatest version, to be unleashed.

While the first release candidate should be published by the end of this month, we would like to cover some of the most important changes we introduced in a platform which we rewrote almost from the ground up (40,000 lines of Scala code and counting), while keeping the familiar look&feel our longtime users came to expect.In a previous blog post, we covered TheHiveFS, a nifty feature of TheHive4 that allows you to quickly access all files stored in TheHive directly from your investigation machine. It’s time now to get a look under the hood of THeHive 4.

My Time is Precious. TL;DR Please

A picture is worth a thousand words, right? Here you go then!

The Hive 4’s Brand New Architecture

I am Puzzled, can you Elaborate a Bit?

So, you are not in a hurry anymore? Fine. Here, grab a seat, a glass of Gevrey-Chambertin and tasty Burgundy snails. All set? Let’s start then!

TheHive 4 will be the first version to use a graph database instead of Elasticsearch. Yes, you read that correctly. TheHive 4 won’t support Elasticsearch anymore but fear not fearless cyberdefender. Your friendly bees will not leave you hanging. If you are already using TheHive 3.4.x, we will provide a migration tool that will move your existing data to the new storage system (with no losses or bit flips hopefully).

We haven’t decided to ditch Elasticsearch on a whim or because Thomas (Franco, not Chopitea nor the General) dropped his leftist hipster attitude for a tight, tailor-made dictator uniform straight out of Spain. For all its greatness, ES has some annoying limitations which prevented us from adding, in an elegant, haiku-like way important features such as multi-tenancy, RBAC and large file management, while laying the ground for the future (stop being curious, the future has not been invented yet and when we do invent it, we’ll let you know).

Using JanusGraph, TheHive 4 structures information in graphs and stores them in an Apache Cassandra database. All the files that you attach to task logs or add as observables are stored in a Hadoop Distributed File System (HDFS).

Thanks to this brand new architecture, TheHive 4 is horizontally scalable. You can add as many TheHive, Cassandra and HDFS nodes to your Security Incident Response Platform cluster and sustain whatever load you might be facing without a sweat. Who said FOSS can’t be ‘enterprise grade’ (whatever that means in marketing lingo)?

A Tour d’Horizon of the Main Features

TheHive 4, boosted by all the passion and skills of Zen Master Franco and MC Adouani, will support, in addition to TheHiveFS:

  • Multi-tenancy
  • RBAC
  • 2FA
  • Web configuration
  • API versioning

We will cover some of these features in greater detail in future instalments. In the meantime, let’s take a ride in a helicopter and view the wonderful landscape laying before us from above. After you Messieurs-Dames, we are French gentlemen and gallantry is of the essence (except when we use the public transportation in Paris, then savages we become).

Multi-Tenancy

As in Cortex, you will be able to create multiple organisations within a single instance of TheHive 4. In addition, an organisation can decide to share a case or parts of it (say a task, some observables, etc.) with other organisations. That way, a peer organisation or a constituent can contribute to the investigation at hand, provide essential information, etc.

RBAC

TheHive 4 supports a large set of user permissions. Some pertain to administrators, others to users and there are also permissions that apply to connectors. For example, users can manage tasks but not observables. They can have the power to share a case or part of it with sister organisations and execute Cortex analyzers but not responders.

You will be able to create roles for users, and, at the organisational level, what we call shares. RBAC deserves its own blog post and we’ll get to it pretty soon.

2FA

Do you really want us to describe this one? Before you answer yes, we’d like to remind you that you are in a helicopter. Just sayin’.

‘They asked me to explain 2FA. So I helped them out of the helicopter. It was flying way above ground.’

Web Configuration

Tired of using vi, Emacs or your favourite CLI editor for making configuration changes to TheHive’s application.conf? Tired of restarting the service to take into account those modifications? Then you will certainly go dance kizomba with Nabil all night long when we tell you that you don’t need to use vi & service (or whatever the kids are using these days) anymore!

Thanks to the new architecture, all the configuration will be stored in the underlying database and you will be able to edit it using the WebUI. TheHive will automatically take the changes into account and you won’t need to restart it.

We can feel your love here. Merci !

API Versioning

TheHive 4 adds API versioning and it will maintain backward compatibility with TheHive 3.4.x without preventing us from adding new features. TheHive4py will not be updated right away for TheHive 4 but thanks to the backward API compatibility, all existing feeders and programs that use the current version of TheHive4py will still work out of the box.

That’s all folks! Stay tuned for further news and, in the meantime, don’t be blue cuz’ the bees gonna take care of you.

Cortex 3.0.1: The ‘Better Logging’ Edition

Lo and behold, we aren’t dead & TheHive Project ain’t toast! So, foremost, Happy New Year folks (we are still in January, right?)! We have some nice gifts coming up for you, gifts that have required very heavy-duty work. Of course, you might complain that we haven’t been responsive as of late but hey, there’s only so much we can do, right?

Happy New Year Folks! (Photo by Saâd Kadhi)

We’ll talk about those gifts in the upcoming weeks. In the meantime, there’s a new Cortex version in town and we urge you to upgrade to it, particularly if you consider deploying several Cortex nodes as a cluster. Indeed, Cortex 3.0.1 fixes a missing dependency that is required to set up such an architecture. Additionally (and this is the part where you should be paying attention), this version fixes the display of error messages pertaining to analyzer and responder operations, and also ensure that old responders and analyzers no longer show up once you clicked on that Refresh button.

Fixes and Enhancements

  • #244 Prevent the Play secret key from being displayed in the logs at startup. Nonetheless, you can still display it (for troubleshooting purposes or to make things easier for attackers that might have access to the logs and be interested in such a world-changing secret) by using the --show-secret option when starting Cortex
  • #243 fixes the display of error messages when analyzers & responders fail
  • #242 Remove references to Google Fonts
  • #238 The Docker image had 4 critical CVEs and 69 high CVEs (*cough*). Contributed by Micheal Hart
  • #239 Missing dependency for cluster bug
  • #234 fixes a bug where old, non-existent analysers were still showing in Cortex after an upgrade. Contributed by daskydasky
  • #241 Analyzer reports no output when it fails
  • #240 An encoding issue causes an invalid format in the catalog file
  • #230 Elastic4play has dropped the ES cluster configuration option. Contributed by Adeel Ahmad
  • #164 Handle second/minute-rates limits on Flavors and Analyzers

Running Into Trouble?

Shall you encounter any difficulty during the upgrade process, please ask on our user forum, get in touch with the community on Gitter, or send us an email at support@thehive-project.org.

Unleash the Power of Dockerized Analyzers in 5 Minutes

One of the big improvements you’ll notice in Cortex 3 is the support for dockerized analyzers. And amongst some of their benefits, the installation process has been significantly simplified. So let’s assume you do not want to bang your head against Python, or other library dependencies. Then read one for a way to set up analyzers and run them quickly.

The following instructions have been tested on Ubuntu 18.04. If you already have a Cortex instance up and running, you can jump directly to the docker installation section below.

Install System Packages

Prerequisites

  • Ensure your system contains the required packages:
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
  • Oh, and Cortex should have access to the internet 😉

Cortex

Configure your system to install packages from TheHive-Project repositories.

echo 'deb https://dl.bintray.com/thehive-project/debian-stable any main' | sudo tee -a /etc/apt/sources.list.d/thehive-project.list
sudo apt-key adv --keyserver hkp://pgp.mit.edu --recv-key 562CBC1C

Install Cortex:

sudo apt-get update
sudo apt-get install cortex

The Cortex files will be put in /opt/cortex. The Cortex binary will be executed using the cortex account.

The configuration file is /etc/cortex/application.conf.

The Cortex log file is /var/log/cortex/application.log.

Docker

We recommend reading the Docker documentation to install the software.

For Ubuntu 18.04, you can run the following commands: 

wget -O- https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"
sudo apt-get update 
sudo apt-get install docker-ce

Use Docker with Cortex

Start by giving the cortex account the permission to run Docker.

usermod -a -G docker cortex

Next, in the Cortex configuration file (/etc/cortex/application.conf) ensure jobs will be executed using Docker:

job {
  runner = [docker]
}

Follow the Standard Analyzer Catalog

If you are a complete Cortex noob, please read the Quick Start Guide.

Configure Cortex to get the catalog with up-to-date versions of analyzers. Edit /etc/cortex/application.conf to set the catalog URLs in the analyzer configuration section as shown below:

## ANALYZERS
#
analyzer {
  urls = ["https://dl.bintray.com/thehive-project/cortexneurons/analyzers.json"]
[..]
}

Once Cortex is configured, restart the service with the following command, wait a few seconds and you should be able to connect to Cortex on https://<cortex_host&gt;:9001 et voilà!

sudo service restart cortex

Important Note: The catalog analyzers.json contains information regarding versions of analyzers we consider stable and that are updated with bug fixes. This is typically synchronised with our master branch on Github. When you are using this catalog, you are de facto benefiting from the latest analyzer updates without needing to refresh anything in Cortex or setup again the configuration to get the latest version.

We also provide two additional catalogs:

  • analyzers-stable.json which strictly follows versions of analyzers if you do not want any uncontrolled updates. What does that mean in practice? You will have to click on the Refresh button in Cortex to update your analyzers, disable old ones and enable new versions. Moreover, you will also have to setup again their configuration. Typically, if you installed and setup Cortex with this catalog and the current version of FileInfo analyzers is 6.0, you won’t benefit from the next version, let’s say 6.1, unless you refresh Cortex.
  • analyzers-devel.jsonwhich contains information about new analyzers or version of analyzers that contains code that has been reviewed but not tested enough (or even not tested at all at times) to be deemed ready for production environments. This is typically synchronized with the develop branch of our Github repository.

Same goes for responders. All available catalogs for Cortex are published on bintray so you can choose the one that better fits your needs (or your risk/gambling profile :p).
