Ali Cortex and the 40 Analyzers

Two months ago, TheHive Chefs announced that Cortex passed the 30 analyzers mark as they added HybridAnalysis, EmergingThreats and Shodan, all three contributed by our continuously growing user community.

It’s 2018 already and to wish you a very happy new DFIR year, Nils and Jérôme got out of their way and reviewed many outstanding pull requests for new analyzers and fixed several bugs. Kudos bees!

The latest release of Cortex-Analyzers, v 1.8.0, contains not one, not two, not even three but ten new analyzers! Isn’t that good omen for a fresh new year fighting cybercrime?

The ten new analyzers, described below, are:

  1. Bluecoat: contributed by our longtime friends from CERT La Poste.
  2. C1fApp: submitted by Dimitris Lambrou.
  3. Censys.io: developed by Nils Kuhnert, now a full member of TheHive Project, on behalf of CERT-Bund.
  4. MISP WarningLists: Nils strikes again (watch out Jérôme! the youngster is gonna leave you way behind ;).
  5. Onyphe: contributed by Pierre Baudry and Adrien Barchapt. It comes in five different flavors.
  6. PayloadSecurity: submitted by Emmanuel Torquato. The analyzer comes in two flavors.
  7. Robtex: added by… Nils again! It has three flavors.
  8. SinkDB: guess who developed that one? Wow, impressive! How did you figure it out? Yes, Nils!
  9. Tor Blutmagie: contributed by Marc-André Doll.
  10. Tor Project: also contributed by Marc-André Doll.

We would like to wholeheartedly thank all the individuals and teams listed above for their invaluable contributions. So a big merci for your work!

Bluecoat

The Bluecoat analyzer queries the Symantec – previously known as Bluecoat – WebPulse site review API for the currently assigned site category of URLs or domains. The analyzer needs no further configuration. When executed through TheHive, the analyzer produces short and long reports as shown below:

C1fApp

The C1fApp analyzer queries the C1fApp service, an Open Source threat feed aggregation application, using the API for IP addresses, domains and URL.

Before using the analyzer, you need to create an account on the C1fApp website and get the associated API key which you’ll need to provide as a value for the key parameter of the analyzer config section of /etc/cortex/application.conf as shown below. Once you’ve done so, you’ll need to restart Cortex.

 C1fApp {
     service="query"
     key="<insert API key here>"
     url="https://www.c1fapp.com/cifapp/api/"
 }

When launched using TheHive, the analyzer produces short and long reports such as the following:

sc-short-c1fapp.png

sc-long-c1fapp.png
TheHive: C1fApp 1.0 Analyzer – Short and Long Report Samples

Censys.io

Censys.io continually monitors every reachable server and device on the Internet, so you can search for them and analyze them in real time. Using the corresponding analyzer, information about a website certificate can be obtained using the associated IP, domain or certificate hash.

In order to use this analyzer, an account at censys.io has to be registered and the API ID and secret need to be added to the Cortex configuration file:

Censys {
    uid="<Your ID here>"
    key="<Your secret here>"
}

Once done, you’ll have to restart Cortex. When ran from TheHive, the analyzer produces short and long reports such as the following:

Censys Short

Censys.io Analyzer
TheHive: Censys 1.0 Analyzer – Short and Long Report Samples

Details about the ports can be obtained with a click on the specific button.

MISP WarningLists

In order to detect false positives soon enough in the analysis process, our good friends at the MISP Project published their so called warning lists which contain lists of well-known services or indicators.

This analyzer queries observables against the MISP warning lists. Observables can be an IP address, a hash, a domain, a FQDN or a URL.

To iterate through all the warning lists, the repository itself must be available on the Cortex instance:

git clone https://github.com/MISP/misp-warninglists

We highly recommend you create a cron entry or use a similar mechanism to keep the lists fresh. While the default path for the lists is the misp-warninglists subdirectory it can be adjusted in the configuration file:

 MISPWarningLists {
     path = "/path/to/misp-warninglists/repository" # Default: "misp-warninglists"
 }

When called from TheHive, the analyzer produces short and long reports as shown below:

firefox_2018-01-10_11-01-46

MISP Warninglists Analyzer
TheHive: MISP WarningLists 1.0 Analyzer – Short and Long Report Samples

As you can see, The MISP WarningLists analyzer checks if the repository is up-to-date 😉

Onyphe

The Onyphe analyzer leverages Onyphe’s API to query the service, which provides data about the IP address space and the publicly available information in a single, handy location.

The service comes in five flavors:

  • Onyphe_Forward: retrieves forward DNS lookup information we have for the given IPv4/IPv6 address with history of changes.
  • Onyphe_Geolocate: retrieves geolocation information for the given IPv4/IPv6 address.
  • Onyphe_Ports: retrieves synscan information we have for the given IPv4/IPv6 address with history of changes.
  • Onyphe_Reverse: retrieves reverse DNS lookup information we have for the given IPv4/IPv6 address with history of changes.
  • Onyphe_Threats: retrieves Onyphe threats information on anIPv4/IPv6 address with associated history.

To use the analyzer, you need to create an account on the Onyphe website. Provide the API key associated with your account as a value for the key parameter and add the lines below to the config section of /etc/cortex/application.conf then restart the cortex service.

Onyphe {
    key = "<insert API key here>"
}

When ran from TheHive, the analyzer produces short and long reports such as the following:

sc-short-onyphe.png

sc-long-onyphe.png
TheHive: Onyphe 1.0 Analyzer – Short and Long Report Samples

PayloadSecurity

The PayloadSecurity analyzer let you submit observables to a on-premises PayloadSecurity instance. To use it, you need to create an account on the PayloadSecurity service. Provide the API/secret pair as  values for the key and secretparameters, collect the URL and environmentid of the service,  and add the lines below to the ​​config section of  /etc/cortex/application.conf. Then restart the cortex service.

PayloadSecurity {
    url = "<insert URL here>"
    key="<insert API key here>"
    secret="<insert secret here>"
    environmentid="<insert environmentid here>"
    verifyssl=True
}

When launched through TheHive, the analyzer produces short and long reports such as the following:

sc-short-payloadsecurity.png

sc-long-payloadsecurity.png
TheHive: PayloadSecurity 1.0 Analyzer – Short and Long Report Samples

Robtex

When collecting data about IPs, domains and FQDNs, Robtex can be a good source of information. According to their statistics, they logged over 20 billion DNS resource records. The corresponding analyzer comes in three flavors:

  • Robtex_Forward_PDNS_Query: checks domains/FQDNs using the Robtex Passive DNS API
  • Robtex_IP_Query: checks IPs using the Robtex IP API
  • Robtex_Reverse_PDNS_Query: checks IPs using the Robtex reverse Passive DNS API

The analyzer uses the free Robtex API which needs no subsequent configuration. However, the free API limits the rate and amount of returned data.

When executed using TheHive, the analyzer produces short and long reports such as the following:

Robtex Short

Robtex Analyzer
TheHive: Robtex 1.0 Analyzer – Short and Long Report Samples

SinkDB

SinkDB is a private service provided by abuse.ch which collects sinkholed IPs. Access to the service is allowed to trusted partners only. If you think you qualify, you can request an access using the form available on the SinkDB website. This is most likely only granted to certain CSIRTs and CERTs and not to individuals.

Provide the API key associated with your account as a value for the key parameter and add the lines below to the config section of /etc/cortex/application.conf then restart the cortex service.

SinkDB {
    key="<insert API key here>"
}

When ran from TheHive, the analyzer produces short and long reports such as the following:

SinkDB Short True

SinkDB Long
TheHive: SinkDB 1.0 Analyzer Short and Long Report Samples

Tor Blutmagie

Tor Blutmagie analyzer extracts data from torstatus.blutmagie.de  and checks if an observable is linked to a Tor node. The observable can be an IP address, a FQDN or a domain.

In order to check if an IP, domain or FQDN is a Tor exit node, this analyzer queries the Tor status service at Blutmagie.de. The analyzer uses a caching mechanism in order to save some time when doing multiple queries, so the configuration includes parameters for the cache directory and the caching duration.

Provide the lines below to the config section of /etc/cortex/application.conf then restart the cortex service.

TorBlutmagie {
    cache {
        duration=3600
        root=/tmp/cortex/tor_project
    }
}

When ran from TheHive, the analyzer produces short and long reports such as the following:

firefox_2018-01-10_11-01-55

Tor Blutmagie Analyzer

Tor Blutmagie Analyzer (2)
TheHive: Tor Blutmagie 1.0 Analyzer – Short and Long Report Samples

Tor Project

Tor Project analyzer has also been contributed by Marc-André Doll. As the above analyzer, this one checks if an observable is a Tor exit node. This time, however, the source of information is the official Tor network status which can be queried for IP addresses only.

The accepts another parameter, ttl, which is the threshold in seconds for exit nodes before they get discarded. Provide the lines below to the config section of /etc/cortex/application.conf then restart the cortex service.

TorProject {
    cache {
        duration=3600
        root=/tmp/cortex/tor_project
        ttl=86400
    }
}

When ran from TheHive, the analyzer produces short and long reports such as the following:

TorProject Short

The Perfect Christmas Gift

George Abitbol* doesn’t feel well. Christmas is approaching at a fast pace and the gift he ordered days ago for his girlfriend didn’t find its way to his mailbox yet. He checked it out three times today and save for some spam catalogues on how to take care of his handsome silhouette, nothing resembling a gift showed up.

IMG_4107.jpg
Picture by Saâd Kadhi

He tried to call the French parcel service to know the whereabouts of the luxurious, limited version of the organic sweet potato chips his lovely Jacqueline* likes so much, which sells for four times the regular price (to bear the cost of the enhanced packaging, certainly), but he couldn’t get hold of a living soul all day long. When he placed the order, the delivery was supposed to be lightning fast. It turned out to be a false promise.

With a sinking heart, he climbs back the stairs leading to his apartment, fetches his laptop and sits on his club chair. With his headphones on, immersed in the wonderful jazz of Christian Scott, he wanders randomly through online shopping sites trying to make out his mind on what other presents he could get for his dear Jacqueline, in time for Christmas.

In the middle of the track called Encryption, featuring the uncanny Elena Pinderhugues on flute, a Twitter notification resonates in his ears. He checks it out and learn that TheHive Chefs, as true and elegant gentlemen, have published a new training VM for Cerana 0.3 (a.k.a. TheHive 3.0.3), including Cortex 1.1.4 and the latest set of Cortex-Analyzers.

George loves bees in all shapes and forms, including digital ones so he swiftly downloads the new VM and as the cautious person he is, he verifies the file’s SHA256 hash: 86a87b70627e8db672c57cb57821461f2564ae9b8087cc22fdd1e7a599c16aedWonderful! Everything checks out beautifully. He then imports the file in his VM software, starts the virtual machine and logs in as thehive then types in thehive1234 when asked for the password.

He thoroughly reads the documentation to configure various analyzers and integrate his favourite Security Incident Response Platform with MISP.  A few minutes later, his VM is ready for prime time and he starts playing with the new multi-source dashboards and interacting with fellow analysts on Gitter.

And he totally forgets about Jacqueline’s gift.

(*) Any resemblance to real and actual names is purely coincidental.

Correction: Dec 23, 2017
An earlier version of this post was referring to a previous training VM that included Cerana 0.2, a version affected by a privilege escalation vulnerability which was corrected in Cerana 0.3. Some typos were corrected as well.

Cerana 0.2: X-Pack Auth, Multi-source Dashboards

TheHive Chefs are happy to announce the immediate availability of their latest recipe: Cerana 0.2 (a.k.a. TheHive 3.0.2).

While TheHive 3.0.0 brought you dynamic dashboards among other niceties, the latest (and, of course, the greatest) version of your Mom’s favourite Security Incident Response Platform fixes a bug spotted by our longtime supporter Megan Roddie (merci !). Indeed, Nabil was running low on coffee so he didn’t make the necessary changes to support the new sighted toggle introduced by Cerana for file observables.

Cerana 0.2 also adds X-Pack authentication for Elasticsearch, a feature contributed by srilumpa. Thanks! To enable this functionality, and assuming the X-Pack plugin for Elasticsearch is installed, add the following section to /etc/thehive/application.conf:

search.username = "jessica"​​​​​

​search.password = "drink-beat-repeat"

Last but not least, we decided to make dynamic dashboards even more powerful. You can now create new graphs that support multiple series from multiple entities (or sources).

Multi-line Dashboards Example — Number of IOCs imported from MISP vs. those imported from other sources

As Christmas is approaching, go ahead and play with dynamic dashboards to impress your management as soon as 2018 rears its head or truly drive your CTI and DFIR activities and plan well ahead how you should improve automation or collaboration (or beg for additional headcount).

Introducing Cerana

Update: 2 days after publishing this blog post, we’ve released Cerana 0.1 (TheHive 3.0.1) which fixes a number of issues. We encourage you to use 3.0.1 instead of 3.0.0.

The friendly honeybees at TheHive’s code kitchen were pretty busy lately even though winter came and temperatures have been close to zero Celsius in Paris, France. As we wrote a couple of weeks ago on this very blog, we are happy to announce Cerana to the world, available immediately.

Cerana or TheHive 3.0.0 is the latest (and obviously greatest) release of a now highly popular open source, free Security Incident Response Platform (or SIRP for short). Its flagship feature in comparison to previous releases is Dynamic Dashboards.

Dynamic Dashboards

Dynamic Dashboards replace the Statistics module in Cerana to allow you to explore the data available in Elasticsearch, which TheHive uses for storage, in many ways. For example, you can have a usage breakdown of Cortex analyzers, the number of open cases per assignee, the number of alerts per source (MISP, email notifications, DigitalShadows, Zerofox, Splunk, …), the number of observables that have been flagged as IOCs in a given time period, how many attributes were imported from MISP instances, top 10 tags of imported MISP attributes or incident categories.

case3.png
Dynamic Dashboards

Dynamic Dashboards can be created by an analyst and kept private or shared with the other team members. Dashboards can also be exported and imported into another instance. This would facilitate community participation in the establishment of valuable data exploration graphs to drive DFIR activity and seek continuous improvement.

When you’ll migrate to Cerana, you won’t have to build dashboards from scratch. We recreated more or less those which were available under the Statistics view and included them in the Cerana build.

Cortex and MISP Health Status

Cerana will also allow you to monitor the health status of all the Cortex and MISP instances that it is connected to. In the bottom right corner of TheHive’s Web UI, the Cortex and MISP logos appear when you have configured the integration with those products as in previous releases. However, the logos will have a small outer circle which color will change depending on whether Cortex and/or MISP instances are reachable or not.

status
Cortex & MISP Health

If TheHive can’t reach N out of M Cortex/MISP instances, the outer circle will be orange. If it can’t reach all M instances, the circle will red. If everything is fine, the circle will be green. The exact status of each Cortex/MISP instance can be seen in the About page. And when you try to run analyzers on a Cortex which cannot be reached, TheHive will tell you so as well.

about
Cortex & MISP: Version & Status

Sighted IOCs

In previous releases of TheHive, observables can be flagged as IOCs. However, this doesn’t necessarily mean you’ve seen them in your network. Think for example of a suspicious attachment which you’ve submitted to Cuckoo or Joe Sandbox through Cortex. The analyzer returns some C2 addresses to which the sample tries to connect to. You’d be right to add those C2 addresses to your case and flag them as IOCs. Then you search for them in your proxy logs and you find connection attempts to one out of four. In previous versions, you’d add a seen label but this would be inconsistent among analysts. One may use found instead. Another will add a description and no labels.

To avoid such situations and give you a simple way to declare an IOC as seen, Cerana adds a sighted toggle which you can switch on/off. We will leverage this toggle in future versions to indicate sightings when sharing back cases to MISP.

Other Features and Improvements

Cerana contains numerous other features and improvements such as:

  • Case template import, export
  • The ability to assign default values to metrics and custom fields to case templates
  •  The ability to assign by default tasks to their rightful owners in case templates
  • Show already known observables when previewing MISP events in the Alerts page
  • Add autonomous systems to the list of default datatypes
  • Single-sign on using X.509 certificates (in BETA currently)

We will update the documentation for Cerana in the upcoming weeks. So stay tuned.

Cerana: a Sneak Peek

Initially planned for Nov 17, 2017, Cerana, the next major release of TheHive, is delayed by a few days for three reasons: fixing a few minor but nonetheless irking bugs, quality assurance, and adding small but nice features that would have otherwise required a new database migration a short while after performing one during the upgrade to this new version.

The new release date for Cerana (TheHive 3.0.0) is Dec 5, 2017, the same day we’ll have our second joint workshop with the fine people of the MISP Project during the Botconf conference in Montpellier, France (food, wine, sightseeing… well you get the picture).

If we should mention a single major Cerana feature to convince you to install it or take it for a spin, that would be dynamic dashboards, with no hesitation.

While it was enough for a start, the Statistics module doesn’t take advantage of the underlying Elasticsearch storage and the many ways we can play with all the data that analysts keep feeding to TheHive. Not only that but what about custom fields, alerts, and so on? Enter Dynamic Dashboards.

 

alerts.jpg
Dynamic Dashboards – Alert types and sources

To put it simply, Cerana will allow you to analyze TheHive data (almost) any way you want and chart it using different options: how many alerts of a certain type have been received during a given period? Over all the cases that are recorded within TheHive, how many observables with a specific tag and flagged as IOCs are there? …

 

Dashboards can be private to an analyst, shared with fellow TheHive users, imported from another instance and exported. By adding the import/export feature, we hope to foster sharing within TheHive community where teams would impart useful dashboards to their peers. Graphs can also be saved as images to add to reports.

observable_sources
Dynamic Dashboards – Sources of observables

To alleviate upgrades, Cerana will come with a few dashboards out of the box to mimic the Statistics module hence you won’t lose existing functionality when you make the move. At this stage, we’d like to remind you that we only support the current release and the previous one. When Cerana will be published, we’ll obviously support it (genius, n’est-ce pas ?) as well as Mellifera 2.13.2. Nothing else.

cases.png
Dynamic Dashboards – Case status, resolution and impact

Cerana will also give you the ability to import and export case templates, a feature that has been requested by our growing user base. This could be a first step towards a global repository where case templates can be shared, refined and created according to common standards, regulations or compliance requirements. Think LPM in France, NIS in Europe, GDPR, etc. Case templates will also be improved to contain default metrics values if needed and automatically assign tasks to given analysts.

Another addition worth mentioning is the sighted flag for IOCs. When an analyst flags an observable as IOC and as sighted, it means that observable is not simply something coming from a sandbox analysis (think C2) or from a 3rd party but was confirmed as being used by a threat actor in your network. In a later release, exporting cases to MISP instances will make use of this new flag to feed MISP attribute sightings. The sighted value will also be used in the future to improve alert previewing.

Last but not least, Cerana will supervise the ‘health’ of the Cortex and MISP instances it is integrated with. The Cortex and MISP logos at the bottom right corner of TheHive UI appear when integration with those products is enabled. They will also have a coloured circle to indicate health:

  • Green: TheHive can reach all of the configured Cortex/MISP instances.
  • Orange: TheHive cannot reach all of them.
  • Red: no instance can be reached.

There are other areas (the About page, the observable analysis buttons…) where the health of Cortex and/or MISP can be monitored.

Now, if you don’t mind, we have some coding to do. We’d better get back to it if we want to give you a luscious release. À bientôt !

Training VM Reloaded: Mellifera 13, Cortex 1.1.4 & Other Updates

Mellifera 13: Export to MISP, Webhooks, API Keys & ES 5

TheHive Project French Chefs are very happy to announce Mellifera 13 (TheHive 2.13.0), a brand new, all shiny, major version of TheHive.

This new edition of your favorite Security Incident Response Platform (SIRP) has been cooked with great care to bring you a number of key features.

Mellifera 13 now uses ElasticSearch 5.x. We have tested it with v 5.5 but it should work just fine with ES 5.6.

Webhooks

TheHive has now basic support for webhooks. This allows your SIRP to post all the audit trail data to one or multiple webhooks defined in the configuration file. This way, you can listen to any change taking place on the platform and act on it as you see fit: create a ticket in an IT ticketing system, send a message to a Slack channel, display selected events of the audit trail on a screen, wake up your fellow analysts from sleep when a specific type of cases or a given alert is raised & so on. So get some elbow grease and code that Slack bot promptly 😉

Import and Export from Multiple MISP Servers

Mellifera 13 can not only import events from multiple MISP servers but also export cases as events to one or several MISP instances. The exported cases will not be published automatically though as they need to be reviewed prior to publishing.

Export_Case_1.png
Click on that Share button on the top right corner
Export_Case_2.png
Select the MISP server to which to export the case
Export_Case_3.png
See how the Share counter on the top right corner has now increased

We strongly advise you to review the categories and types of attributes at least, before publishing the corresponding MISP events. Please also note that only and all the observables marked as IOCs will be used to create the MISP event. Any other observable will not be shared. This is not configurable. For further details, check the documentation.

Export_Case_4.png
Review and publish the event on MISP
Export_Case_5.png

API Keys

Mellifera 13 introduce a new authentication mechanism: API keys. This auth method is recommended for all programs or scripts, including your SIEM, that raise alerts on TheHive. You can, as an administrator, generate and revoke as many API keys as you want. Existing software using the basic authentication method should be modified to use API keys. But do not panic, while the basic authentication mechanism has been disabled by default, you can still enable it in application.conf.

The ‘alert’ role

A new alert​ role has been added. Only users with this role can create an alert. All existing programs which create alerts must have this role. Otherwise they will no longer work.

Download & Get Down to Work

If you have an existing installation of TheHive, please follow the migration guide. This is paramount to ensure a good transition from earlier versions. You have been warned.

If you are performing a fresh installation, read the installation guide corresponding to your needs and enjoy. Please note that you can install TheHive using an RPM or DEB package, use Docker, install it from a binary or build it from sources.

Mellifera 12.1 Released

About a month ago, we published Mellifera 12 which brought numerous features such as mini-reports on the observable page, custom fields, alert similarity or template selection during alert imports.

Great, palatable recipes, even if they are cooked by fine French chefs, need to be refined over time and may not be as savoury as intended when they are served in their early days. Quality takes time, although smokeware vendors would have you think otherwise.

Mellifera 12.1 (TheHive 2.12.1) has been released to fix a number of outstanding bugs:

  • #249: renaming of users does not work
  • #254: TheHive does not send the file’s name when communicating with Cortex
  • #255: merging an alert into an existing case does not merge the alert description into the case’s description
  • #257: while TheHive does not let you add multiple attachments to a single task log, the UI makes you believe otherwise
  • #259: fix an API inconsistency. GET /api/case/task/:id/log has been fixed.
    And a new API call POST /api/case/task/:taskId/log/_search  has been added, which accepts a “query” in the request body to filter logs of the task.
  • #268: cannot create an alert if the IOC field is set for a single alert’s attribute.
  • #269: closing a case with an open task does not dismiss it from ‘My Tasks’.

This new minor release adds the following enhancements:

  • #267: fix warnings in the DEB package.
  • #272: in alert preview, similar cases are shown regardless of their status. Merged or deleted ones should not appear in that list.

How About the Test VM?

The test VM has not been updated yet. It still contains Mellifera 12 (TheHive 2.12.0). We will update it in September, probably when Mellifera 13 is released. That version will bring the ability to export cases as MISP events.

Download & Get Down to Work

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

If you are performing a fresh installation, read the installation guide corresponding to your needs and enjoy. Please note that you can install TheHive using an RPM or DEB package, use Docker, install it from a binary or build it from sources.

Train till you Drain: TheHive & Cortex VM

Rejoice folks! You can now play with TheHive & Cortex thanks to the test VM we created. It includes Mellifera 12, the latest major version of TheHive, Cortex 1.1.3, the latest Cortex analyzers with all dependencies and ElasticSearch installed on top of Ubuntu 16.04 with Oracle JRE 8.

The test VM is intended to be used… well… for testing or training purposes. We strongly encourage you to refrain from using it for production.

Get It

You can download the VM from the following location:

https://drive.google.com/file/d/0B3G-Due88gfQYWR6WVlkLWhRemM/view?usp=sharing

To ensure that your download went through nicely, check the file’s SHA256 hash which must be equal to the following value:

17df5989d852583e3046daefb97caadff90d30ecf4402df69cf6036d7ad1cacd

The system’s login is thehive and the associated password is thehive1234.

Use It

You can start using TheHive & Cortex once the VM is started. To access TheHive, point your browser to the following URL:

http://IP_OF_VM:9000

For Cortex, the port is 9999:

http://IP_OF_VM:9999

Configure TheHive

The first time you access TheHive, you’ll need to create the associated database by clicking on the Update Database button as shown below:

Screen_Shot_2017-07-06_at_21_52_46.png
Update TheHive’s Database on First Access

TheHive’s configuration file is located in /etc/thehive/application.conf. For additional configuration, read the docs.

Cortex

TheHive is already configured to use the local Cortex service.

Analyzer and Associated Report Templates

To fully benefit from the analyzers, you should install the associated report templates:

  • download the report template package
  • log in TheHive using an administrator account
  • go to Admin > Report templates menu
  • click on Import templates button and select the downloaded package
Plug it with MISP

The test VM does not contain a MISP instance and none is configured in TheHive’s configuration file.  To play with MISP, you may want to use the VM our good friends at CIRCL provide.  Once you’ve downloaded it or if you have an existing instance, edit /etc/thehive/application.conf and follow the configuration guide.

Restart or Go Mad

After each modification of /etc/thehive/application.conf do not forget to restart the service:

$ sudo service thehive restart

Troubles?

TheHive service logs are located in /var/log/thehive/application.log.

Configure Cortex

All available analyzers are installed with their dependencies, but none is configured. To configure analyzers, edit /etc/cortex/application.conf and follow the configuration guide.

Restart or Go Mad

After each modification of /etc/cortex/application.conf do not forget to restart the service:

$ sudo service cortex restart
Troubles?

Cortex service logs are located in /var/log/cortex/application.log.

An earlier version of this post offered to download the VM from Dropbox but they suspended the associated link due to seemingly heavy traffic. The post was updated to replace the Dropbox link with a Google Drive one.

All Fresh CortexUtils, New Cortex Analyzers

Ahead of the imminent release of Mellifera 12 (TheHive 2.12.0), a new, major (as in MAJOR) version of your (soon to be?) favorite Security Incident Response Platform, we’ve made rather significant changes to Cortex analyzers and released a new version of the CortexUtils Python library.

TL;DR

If you are in a hurry:

$ sudo pip install cortexutils --upgrade
$ cd where/your/analyzers/are
$ git pull master

Adjust the Cortex configuration for the new MISP 2.0 analyzer and for Hippocampe as shown below if you are using these analyzers then import the corresponding report templates into 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

CortexUtils 1.2.0

CortexUtils has been updated to include a new function called build_taxonomy() which is required for analyzers relying on the Python library we released to make their development development easier.

Mini-Reports in The Observable Tabs

Starting from Mellifera 12 (TheHive 2.12.0), mini-reports will be displayed in the observable tab in each case as soon as an analysis has been completed. Now analyzers compute their short/mini reports and put them in the summary section of their JSON output, ready for consumption. TheHive 2.12.0 and up will no longer create them on-the-fly.

Taxonomy

The mini-reports of all the analyzers have been updated to comply with a taxonomy that is similar to the one we were already using for VirusTotal:  VT:Score="14/56”.  A “maliciousness” level was already included in TheHive’s analyzer templates and we used a specific color to display each level. This level is now produced directly by the analyzers:

  • info / blue: the analyzer produced an information, and the short report is shown in blue color in TheHive.
  • safe / green : the analyzer did not find anything suspicious or the analyzed observable is safe (according to the analyzer). TheHive displays the short report in green color.
  • suspicious / orange : the analyzer found that the observable is either suspicious or warrants further investigation. The short report is orange colored in TheHive.
  • malicious / red : the analyzer found that the observable is malicious. The short report is displayed by TheHive in red color as show below:

sc-short-VT.png

The short report is built with the summary() function of an analyzer. The build_taxonomy() of cortexutils mentioned earlier should help building it.

MISP 2.0

The MISP analyzer has been updated to version 2.0 and includes new functionality submitted by our long-term contributor Nils Kuhnert from CERT-Bund (thanks a heap!). Unlike the previous version, v 2.0 will let you search for an observable in multiple MISP servers at the same time.

The analyzer accepts a truckload of datatypes as input. To make it work, install the pymisp Python library. It should already have been installed if you are just updating your current analyzers. You will also have to change Cortex configuration file (application.conf) for this new version:

MISP {
 url=["https://mymispserver_1", "https://mymispserver_2"]
 key=["mykey_1", "mykey_2" ]
 certpath=["", ""]
 name=["MISP_SERVER_NAME_1", "MISP_SERVER_NAME_2"]
}

Important note: You have to adjust your existing configuration to match the one shown above. The certpath variable can be left blank if you are not using a self-signed certificate.

When called from TheHive, the following output is produced:

sc-short-MISP.png

sc-MISP-long.png
TheHive: MISP 2.0 Analyzer – Short and Long Report Samples

The short report will show the number of unique events found in all MISP servers while the long report will show information of each matching event in each MISP server.

CERTatPassiveDNS

The CERTatPassiveDNS analyzer is a new submission by Nils (thanks again). It lets you check the CERT.at PassiveDNS service for a given domain or hostname. It takes domains and FQDN as input.

Access to the CERT.at service is allowed to trusted partners only. If you think you qualify, please contact CERT.at. You do not need to add specific information into the Cortex configuration file to benefit from this analyzer as it calls the whois system command to perform the pDNS requests.

When called from TheHive, the following output is produced:

Miscellaneous

The latest version of the Cortex-analyzers repository also include the following bug fixes and improvements:
