TheHive4py 1.5.1 Released

When you need to interact with TheHive’s REST API and you ain’t shy of working with Python, TheHive4py is the way to go. It’s a free, open source library we provide to allow you to easily create alert feeders, automate certain tasks like creating cases, assign them to analysts and much more. For example, Synapse, DigitalShadows2TH and Zerofox2TH leverage the library to send alerts to your favourite SIRP/SOAR.

Sometime ago, we decided that it was time to overhaul the whole library and we began working on version 2.0.0 which will be easier to use. It should also support the full set of TheHive’s REST API calls. In the meantime we decided to release version 1.5.0, shortly followed by version 1.5.1 to support some new functionality contributed by our user community and correct a few issues.

Cortex 2.1.0: The Response Edition

We released Cortex 2.1.0 as a release candidate back in July 31, 2018 along with TheHive 3.1.0-RC1. By then, the power duo which makes digital forensics, incident response and, to an extent, cyber threat intelligence, better, faster, happier, regular exercising gained the ability to perform active response.

We ate our own dog food for a couple of months. We found bugs. We added enhancements and we listened to the early adopters of these new major versions. And today we are thrilled to announce the availability of the stable release of Cortex 2.1.0 along with TheHive 3.1.0.

Cortex 2.1.0 restores the ability to query the analysis and response engine from MISP for enrichment purposes. A new version of the de facto standard for threat sharing should be released shortly as there are also some API-related issues on its side to make the integration fully working again.

Cortex 2.1.0 also gives you the ability to see the PAP (Permissible Actions Protocol) values for each analyzer as well as any custom cache values you might have configured.

You can check out the full changelog and we highly encourage you to install this new version and let us know what you think of it.

Keep Them Coming: Hashdd, URLhaus & a Revamped FileInfo analyzer

We are happy to announce the immediate availability of a new major version of Cortex-Analyzers. Version 1.11.0 includes two brand new analyzers, several updates and a few bug fixes:

  • Hashdd, contributed by  iosonogio
  • URLhaus, contributed by  ninoseki
  • The Domaintools analyzer has been updated with two new flavors: Risk and Reputation
  • The VirusTotal analyzer can (finally!) get reports for URL observables
  • MsgParser and File_Info have been merged in a new, shiny, completely rewritten FileInfo analyzer

As we are approaching the 90 analyzers mark, we wholeheartedly thank our user community for continuously contributing new analyzers, testing them and helping us improve the existing ones.

Important Notice

We made significant changes in this release in the analyzers and short reports. Prior to Cortex-Analyzers 1.11.0, the summary() function in the analyzer code generates a result such as:

"taxonomies": [{
     "level": "suspicious",
     "namespace": "DT",
     "predicate": "Risk",
     "value": "\"10\""
 }]

Double quotes were included in the resulting value. We decided to update the summary() function and make it generate the same result without double quotes :

"taxonomies": [{
     "level": "suspicious",
     "namespace": "DT",
     "predicate": "Risk",
     "value": "10"
 }]

To display the double quotes in TheHive, we updated all short reports to include them:

<span class="label" ng-repeat="t in content.taxonomies" ng-class="{'info': 'label-info', 'safe': 'label-success', 'suspicious': 'label-warning', 'malicious':'label-danger'}[t.level]">
     {{t.namespace}}:{{t.predicate}}="{{t.value}}"
</span>

Hashdd

hashdd.com is a search engine for file hashes which automatically queries 3rd party services like VirusTotal and enriches the information provided based on the 3rd party data. The analyzer includes two flavors: Status and Detail. The first one is used to query hashdd without an API key for the threat level only. The latter produces additional meta information about the sample, but requires an API key.

Results are displayed in TheHive in the following manner:

Hashdd short report

Hashdd status long report

Hashdd detail long report
hashdd — short and long report samples

URLhaus

URLhaus, a service that shares the latest malware download URLs and reports those sites to their respective hosting companies, can now be queried for domains, URLs and hashes. If the observable is found, available information will be displayed as follows:

URLhaus short report

URLhaus long report
URLhaus – short and long report samples

Domaintools Risk and Reputation

New Risk and Reputation services from Domaintools have been added as new flavors to the existing Domaintools analyzer set.

Risk Evidence

The DomainTools Risk Score predicts the risk level and likely threats from a domain that has not been observed in malicious activities, by analyzing various properties of the domain as soon as it is registered.

sc-DTrisk-short

sc-DTrisk-long
Domaintools Risk Evidence – short and long report

Reputation

The Domaintools Reputation Score gives indications about how closely a domain is related to known bad domains, actors, and IPs.

sc-DTReputation-short

sc-DTReputation-long
Domaintools Reputation – short and long report samples

An All New FileInfo

FileInfo performs local static analysis of file observables. It has been completely rewritten from the ground up to be more flexible thus it can easily be enriched with new supported file types and analysis modules. We took this opportunity to merge MsgParser, in charge of extracting and displaying Outlook emails into FileInfo.

As of this release, FileInfo now supports PDF, PE, MS Office documents and Outlook .msg files. We also added support for DDE detection and link extraction in MS Office documents, thanks to Decalage who added this in Oletools since v0.52.

sc-FileInfo-short

sc-FileInfo-long2
FileInfo – short and long report samples

Bug fixes

  • #286 : we updated the way MISP analyzer validates its SSL configuration

  • #292 : we fixed the API URL of malwares.com in the Malwares analyzer

Get It While Supply Lasts!

Each analyzer comes with its own, pip compatible requirements.txt file. To update your Cortex analyzers to 1.11.0, 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.

Update TheHive Report Templates

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

Cortex 2, TheHive and a Whole Slew of Updates

After announcing Cortex 2.0.0 and TheHive 3.0.7, the first version of your favorite SIRP that is (supposedly) compatible with the brand-new version of Cortex, last week, we thought it was time to relax and enjoy the upcoming, long Easter weekend, the sunny sky of Paris (if you can pierce the veil of the Forever Grey Cloud™ that is hanging over the city of lights), and great jazz music. Heck, I even tweeted about it … only to be proven wrong by Life (and Murphy).

We literally field tested Cortex 2 for 3 weeks, we squashed bugs here and there, until almost the very last minute before the release. And yet, our QA needs to be improved by leaps and bounds as we had to release Cortex 2.0.1 one day after unveiling 2.0.0 to correct some additional bugs. And then some members of the core team and of our growing user community took it for a spin. And all hell broke lose. Well, almost 🙂

Session collisions (when TheHive and Cortex 2 are used on the same machine), analyzer malfunctions, connectivity problems … issues that were not identified during the testing phase, even in a production environment, where everything worked as expected. And we call this ‘Computer Science’. Right, right…

So we worked hard, took out our Code Hammer (it’s like Thor’s but cyber) and blasted away all the bugs that we found out or that were reported to us (arigato gozaimasu!) and we are happy to announce the immediate availability of Cortex 2.0.2, TheHive 3.0.8, Cortexutils 1.2.3 and Cortex-Analyzers 1.9.2.

TL;DR Install or upgrade Cortex 2.0.2, update Cortexutils, git pull the Cortex-analyzers repo to get the latest version of the repository, upgrade to TheHive 3.0.8, follow the Quick Start Guide and have a drink.

If you have time (which is admittedly quite scarce nowadays), please read on the changelogs:

What’s Next?

As stated in the previous post, we will release a new version of Cortex4py in order to make it compatible with Cortex 2, continue the work we started with our MISP Project friends to support MISP attribute enrichment through Cortex 2 (MISP currently only supports enrichment using Cortex 1), and perform a long-overdue overhaul of our documentation. We will also release a brand new version of TheHive4py.

Last but not least, we’ll take a hard look at ourselves and our QA. You expect us from us high quality and we hold ourselves to high standards. And we will deliver.

Cortex Hits the 30 Analyzers Mark

Cortex has now 30 analyzers thanks to Daniil Yugoslavskiy, Davide Arcuri and Andrea Garavaglia (from LDO-CERT) as well as our longtime friend Sébastien Larinier. Their contributions, all under an AGPLv3 license, add handy ways to assess observables and obtain invaluable insight to an already solid Threat Intelligence and DFIR toolset.

In addition to these 3 new analyzers, v 1.7.0 of the Cortex-Analyzers repository also fixes a number of bugs and add a few improvements to existing analyzers as well.

To get the new release, go to your existing Cortex-Analyzers folder and run git pull.

HybridAnalysis

The HybridAnalysis analyzer has been contributed by Daniil Yugoslavskiy. It fetches Hybrid Analysis reports associated with hashes and filenames. This analyzer comes in only one flavor called HybridAnalysis_GetReport.

Requirements

You need to have or create a free Hybrid Analysis account.  Follow the instructions outlined on the Hybrid Analysis API page to generate an API key/secret pair. Provide the API key as a value for the key parameter and the secret as a value to the secret parameter, add the lines below to the config section of /etc/cortex/application.conf then restart the cortex service.

HybridAnalysis {
  secret = "mysecret"
  key = "myAPIKEY"
}

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

sc-short-hybridanalysis_1_0.png

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

EmergingThreats

The EmergingThreats analyzer has been submitted by Davide Arcuri and Andrea Garavaglia  from LDO-CERT. It leverages Proofpoint’s Emerging Threats Intelligence service to assess the reputation of various observables and obtain additional and valuable information on malware.

The service comes in three flavors:

  • EmergingThreats_DomainInfo: retrieve ET reputation, related malware, and IDS requests for a given domain.
  • EmergingThreats_IPInfo: retrieve ET reputation, related malware, and IDS requests for a given IP address.
  • EmergingThreats_MalwareInfo: retrieve ET details and info related to a malware hash.

Requirements

You need a valid Proofpoint ET Intelligence subscription.  Retrieve the API key associated with your account and provide it as a value to the key parameter, add the lines below to the config section of /etc/cortex/application.conf then restart the cortex service.

 EmergingThreats {
   key="MYETINTELKEYGOESHERE"
 }

When run from TheHive, it produces short and long reports such as the following:

sc-short-ET_1_0.png

sc-long-ET-1_1_0.png

sc-long-ET-2_1_0.png

sc-long-ET-3_1_0.png

Shodan

The Shodan analyzer is the first submission by Sébastien Larinier. It lets you retrieve key Shodan information on domains and IP addresses.

This analyzer comes in two flavors:

  • Shodan_Host: get Shodan information on a host.
  • Shodan_Search: get Shodan information on a domain.

Requirements

You need to create a Shodan account and retrieve the associated API Key. For
best results, it is advised to get a Membership level account, otherwise a free one can be used.

Supply the API key as the value for the key parameter, add the lines below to the config section of /etc/cortex/application.conf then restart the cortex service.

Shodan {
  key= "myawesomeapikey"
}

When run from TheHive, it produces short and long reports such as the following:

Introducing Cortex4py

Following popular demand, the chefs at TheHive Project‘s code kitchen are happy to announce the immediate availability of Cortex4py.

What Is It?

Cortex4py is a Python API client for Cortex, a powerful observable analysis engine where observables such as IP and email addresses, URLs, domain names, files or hashes can be analyzed one by one using a Web interface or en masse through the API.

Cortex4py allows analysts to automate these operations and submit observables in bulk mode through the Cortex REST API from alternative SIRP platforms (TheHive has native support for one or multiple Cortex instances) and custom scripts.

 

Use It

To install the client, use PIP:

$ sudo pip install cortex4py

 

How Much Does it Cost?

Cortex4py is released under an AGPL license as all the other products we publish to help the IR community fight the good fight. So apart from the effort it’ll cost you to install and use, the price of our software is nada, zero, rien. But if you are willing to contribute one way or another, do not hesitate to drop us an email at support@thehive-project.org or contact us via Twitter.
