Some of our die-hard fans noticed that we silently released TheHive 3.3.0 a few days ago, after six release candidates. Well. Silently won’t be the right word to use in this case as we are drowning under work and feature requests and we sometimes postpone communication in favour of getting true real work done.
So, without any further ado, we are happy to announce the official availability of our latest (and of course greatest) release of the most-advanced, next-gen, HI (Human Intelligence), gluten-free, (add here any keyword that you fancy to help us get the Gartner attention and land in the Magic Quadrant™), free and open source Security Incident Response Platform Security Orchestration Automation & Response Platform.
As stated earlier, TheHive 3.3.0 went through the largest number of release candidates to date in order to ensure it contains more features than bugs (or unexpected functionality as our dear Nabil call them sometimes).
TheHive and Cortex are a huge success. According to our estimates, 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 tried finding a solution to keep TheHive Project as healthy as possible. So we created Creative Source, a nonprofit organisation (NPO), in the hope that we could leverage it to hire more developers thanks to the generous donations of our large user community. Sadly, not everyone in this world is generous and altruistic. At the end, all but one company (yes, exactly one) 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.
As we informed you a few weeks ago, some members of our core team are finalising an alternative option 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 making highly bureaucratic, think-in-the-box-but-never-outside procurement departments freak out.
Spring is here and your favorite bees are busy buzzing flowers to prepare you the most palatable honey ever. In the meantime, we are pleased to announce the immediate availability of Cortex-Analyzers 1.16.0, which adds a new responder and three new analyzers to complete an already hefty collection, bringing the total to 117 analyzers and 3 responders!
One responder has been added:
FalconCustomIOC, contributed by Michael (#421). We don’t know the last name of Michael. That could be Jordan. Who knows?
We could not duly test some of these additions due to lack of access to the associated services or to our legendary laziness. So we would really appreciate it if you could test them and let us know whether they work or not.
The FalconCustomIOC responder let you submit observables from alerts or cases to Crowdstrike Falcon Custom IOC service.
Crowdstrike Falcon is a paid service. An account and an API key are required to configure and run this responder.
AbuseIPDB analyzer let you determine wether an IP has been reported as malicious or not to the AbuseIPDB web service.
An account and an API key is needed to configure and use this analyzer.
TheHive displays the analyzer results as follows:
The BackscatterIO analyzer lets you query the Backscatter.io service for IPs, networks or autonomous systems (AS). It comes in two flavors:
BackscatterIO_GetObservations: determine whether an observables has a known scanning activity
BackscatterIO_Enrichment: enrich your observables with additional information
TheHive displays this analyzer results as follow:
SoltraEdge analyzer lets you query any observable against theSoltra Edge platform.
To configure and use this analyzer, an account, a token key and the base URL of a SoltraEdge server are needed.
TheHive displays this analyzers result as follow:
Get It While Supply Lasts!
Each analyzer and responder comes with its own, pip compatible requirements.txt file. To update your Cortex analyzers to 1.16.0, run the following commands:
cd path/to/Cortex-Analyzers git pull for I in analyzers/*/requirements.txt; do sudo -H pip2 install -U -r $I || true; done && \ for I in analyzers/*/requirements.txt; do sudo -H pip3 install -U -r $I || true; done for I in responders/*/requirements.txt; do sudo -H pip3 install -U -r $I || true; done
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 $I || true; done
The answer is obvious Doctor Watson, right? These highly readable commands (pun intended) allow you to update your Cortexanalyzers and responders to the latest stable versions, downloading new ones in the process, going over all the Python 2 and Python 3 dependencies to install the missing ones and upgrade the old ones to make sure they work correctly. These operations take quite a long time and cause some headaches in the process (Hello, I have Python 3.X and this dependency is no longer required, or Hi, I have an old version of Python 2 and it seems I need this other dependency).
And if you are lucky enough to get it running smoothly, you are still not done as you need to log in to the Cortex UI as an organisation administrator (unlike TheHive, Cortex supports multi-tenancy), click on the Refresh analyzers button under Organization > Analyzers then go to Organization > Responders and click on Refresh responders.
So while the answer to the opening question might be simple, updating analyzers and responders is far from being straightforward, to say the least, even if we forget the ugly fact that both are stored in a repository “conveniently” named Cortex-Analyzers*:
thehive@thehive-training:/opt/Cortex-Analyzers$ 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.
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)_/¯.
Correction: February 15, 2019 Typographical errors have been corrected. Some rewording has been made for the sake of clarity.
We urge our fellow fighters of cybercrime and funny and not-so-funny animals-in-disguise, to update their Cortex analyzers to the latest 1.15.2 version which plugs a serious vulnerability in the Unshortenlink analyzer and fixes several bugs.
On Jan 24, Alexandre Basquin discovered a SSRF vulnerability in the Unshortenlink 1.0 analyzer. By exploiting it, an attacker which has access to a Cortex instance with an analyze role can scan the ports of localhost and possibly of all the hosts reachable by Cortex. This could be automated through Cortex4py by making repetitive calls to the API and thus scanning multiple ports & hosts. In essence, the attacker can perform reconnaissance thanks to Unshortenlink and gain knowledge on which ports are open and which aren’t.
Version 1.1 of Unshortenlink, included in Cortex-Analyzers 1.15.2, plugs this vulnerability by disabling submissions containing IPs & ports. Only URLs are now accepted.
Additionally, Cortex-Analyzers 1.15.2 corrects the following bugs:
#416: the Mailer responder now supports UTF-8 encoding.
#410: remove wrapping of the results produced by crt.sh as a list which ends up breaking the output of the report template. Contributed by Thomas Kastner.
#409: enum is not required for Python 3.4+ to make the MISP Search analyzer work.
#408: FileInfo’s Manalyze plugin did not work after Manalyze renamed plugin_btcaddress to plugin_cryptoaddress.
#406: fix a broken link in the Cymon_Check_IP report, submitted by Manabu Niseki.
click on Import templates button and select the downloaded package
Wait a Minute! Where’s the Blog Post about 1.15.1?
Good catch! There was no blog post about Cortex-Analyzers 1.15.1. Call us lazy but there was nothing Earth-shattering, pole-shifting in that release. Nonetheless, here are a list of fixes included in that release and from which you’ll inherit automatically if you update 1.15.0 to 1.15.2 directly:
#402: Malwares analyzer code relied on functionality that’s only available in Python 3.7+. It has been fixed to work with 3.4 and up thanks to the work of Arcuri Davide.
#404: fixes a bad folder renaming in the HIBP (Have I Been Pwned) analyzer.
#398: MISP Search analyzer wouldn’t run without the enum dependency. Contributed by Mars Huang. Later improved in 1.15.2 (see above).
Dear fellow incident handlers and cybercrime fighters around the world, the galaxy, the known and the unknown universe, first and foremost, all TheHive Project’s team would like to wish a wonderful new year 2019 to you and to your cherished relatives. We truly hope that eagles, pandas, kittens, babars, bears and all sorts of animals will stay out of the way. And remember that you don’t need to go bankrupt by purchasing so-called Next Gen™ magical solutions that work only when there’s a full moon and the page number of the book you are currently reading is 42 to investigate threats 😉
We would like to begin the year by introducing version 1.15.0 of Cortex analyzers, bringing the total number of analyzers to a whopping 113! And thanks to Kyle Parrish, this release improves the Mailer responder to allow you to specify a custom port number for your SMTP server and adds a new one to blacklist observables on Cisco Umbrella utilizing the Enforcement API. The Cisco Umbrella Blacklister responder will then add the tag Umbrella:blockedto the observable.
Cortex-Analyzers 1.15.0 also include fixes and enhancements for Eml_Parser, IBM X-Force, Fortiguard, and Shodan. Most of these modifications were contributed by our continuously growing user community. Thanks to all of those who help us in our mission to provide free and open source security incident response tools to the masses!
Please read the relevant sections in the Cortex installation guide to install or update your analyzers and responders in order to benefit from all this sweet & tasty honey.
3 new flavors for DomainTools, thanks again to ANSSI
This analyzer lets you query the Cyberprotect ThreatScore service for domains and IP addresses. No configuration is needed and it can be used out of the box.
TheHive displays the analyzer results as follows:
Have I Been Pwned
The HIBP_Query analyzer lets you check email addresses on Have I Been Pwned. You can use an optional parameter to include unverified breaches in the search results. Otherwise, it can be used without any additional configuration.
When called from TheHive, results would display as such:
As it name states, The Patrowl_GetReport analyzer will let you get the current PatrOwl report for a FQDN, a domain name or an IP address. You need a running PatrOwl instance or to have access to one to use the analyzer.
If you fire it from TheHive, it would display results as follows:
This analyzer comes in two flavors in order to get Whois data and Passive DNS details using SecurityTrails. To use both flavors, you will need an account for the service to retrieve the associated API key, which you need to configure the analyzers.
SecurityTrails_Passive_DNS displays results in TheHive as follows:
In addition to Shodan_Host and Shodan_Search, which allow you to obtain Shodan information on a host and the search results for a domain name, now you can get domain resolutions (Shodan_DNSResolve), obtain scan history results for an IP address (Shodan_Host_History), get information on a domain (Shodan_InfoDomain) and the reverse DNS resolutions for an IP address (Shodan_ReverseDNS).
The following DomainTools flavors were added to this release:
DomainTools_HostingHistory: get a list of historical registrant, name servers and IP addresses for a domain.
DomainTools_ReverseIPWhois: get a list of IP addresses which share the same registrant information. It applies to a mail, IP, or domain.
Moreover, please note that DomainTools_WhoisLookup now handles IP addresses in addition to domains and provides parsed results. DomainTools_WhoisLookup_IP is thus not needed anymore. Instead, DomainTools_WhoisLookupUnparsed has been added to do the same as DomainTools_WhoisLookup, except that the output results are unparsed.
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.
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 (ExportOnly).
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.
