DigitalShadows Feeder 2.4.5

DigitalShadows2TH 2.4.5, a new version of the DigitalShadows feeder for TheHive, has been released with major improvements.

Source : https://www.bustle.com

Dockerise All The Things!

The most notable one is that you can now use it with docker. Run docker pull thehiveproject/ds2th and create a homedir for configuration and logs.

$ DS2TH_HOMEDIR = /opt/thehive_feeders/Digitalshadows2TH/
$ docker pull thehiveproject/ds2th:latest
$ mkdir -p $DS2TH_HOMEDIR/{config,log}
$ wget -O $DS2TH_HOMEDIR/config/config.py\
https://raw.githubusercontent.com/TheHive-Project/DigitalShadows2TH/master/config.py.template

Edit the config.py before runing the docker command below:

$ docker run --rm --net=host --mount\
type=bind,source="$DS2TH_HOMEDIR"/config,target=/app/config --mount type=bind,source="$DS2TH_HOMEDIR"/log,target=/app/log certbdf/ds2th <OPTIONS>
Quick Installation

If that sounds still complicated, worry not! We also wrote a little program that helps you prepare the environment and install everything. We ensured that it works well on Ubuntu 18.04. The program uses two environment variables to set up everything: FEEDERS_SYSACCOUNT and FEEDERS_HOMEDIR :

$ export FEEDERS_SYSACCOUNT=thehive
$ export FEEDERS_HOMEDIR=/opt/thehive_feeders

There are also sane, default settings in case you did not set any value. DigitalShadows2TH’s home directory will be set to /opt/thehive_feeders/DigitalShadows2TH. To use the script, run the following command line and follow the instructions:

 $ wget -qO- https://raw.githubusercontent.com/TheHive-Project/DigitalShadows2TH/mater/INSTALL/install_with_docker.sh | sudo -E bash -

Custom Case Templates

Previous versions of DigitalShadows2TH allowed only one case template to be associated with alerts created by the feeder in TheHive. Starting from DigitalShadows2TH 2.4.0, you can define a case template for each type of incidents raised by DigitalShadows in the configuration file.

The configuration pertaining to TheHive looks as follows:

TheHive = {
 'proxies':{
     'http': '',
     'https': ''
},
   'url':'THEHIVE_URL',
   'key':'THEHIVE_API_KEY',
   'templates': {
       'default':''
  }
}

Each incident type in DigitalShadows can be associated with a case template in TheHive, for example:

TheHive = {
  'proxies':{
      'http': '',
      'https': ''
  },
    'url':'THEHIVE_URL',
    'key':'THEHIVE_API_KEY',
    'templates': {
        'default':'MY_DEFAULT_CASE_TEMPLATE_FOR_DIGITALSHADOWS_INCIDENTS',
        'DATA_LEAKAGE': 'MY_DATA_LEAKAGE_CASE_TEMPLATE',
        'CYBER_THREAT': 'MY_CYBER_THREAT_CASE_TEMPLATE'
    }
}

A template can be defined for all the following DigitalShadows incident types:

  • DATA_LEAKAGE
  • CYBER_THREAT
  • PHYSICAL_SECURITY
  • SOCIAL_MEDIA_COMPLIANCE
  • BRAND_PROTECTION
  • INFRASTRUCTURE

A default template can be defined for DigitalShadows incidents. If no template is found for a specific incident type, the feeder looks for the default template. if no default template is found, an empty case will be created by when importing the alert.

Update or Install

If you are not using docker, just pull the repository and update your configuration file with the new templates part for TheHive.

Update your Repository
$ cd /opt/TheHive_feeders/DigitalShadows2TH/
$ git pull

The configuration file has changed, so you need to update yours before running the program. A new templates section has been added for TheHive and the path has changed. It is now in the config/ directory of the project.

Install and Use via the Code Repository
$ cd /opt/TheHive_feeders 
$ git clone https://github.com/TheHive-Project/DigitalShadows2TH.git

After that, follow the prerequisites and edit the configuration file. In /opt/TheHive_feeders/DigitalShadows2TH/config/ copy config.py.template to config.py and modify it.

Use cases and detailed configuration instructions can be found in the README file in the repository.

More than 120 ways of Analyzing your Observables

There’s a new version of Cortex-Analyzers in cybertown and its has an awesome, mind-blowing name and that’s… wait for it… wait for it: 2.1.0.

In this new release, we added two analyzers which bring the total number to more than 120:

We could not duly test DNSSinkhole since we do not have access to the associated service. So we would really appreciate it if you could test it and let us know whether it works or not.

Others analyzers have been fixed or improved:

DNSSinkhole

This analyzer lets you check if an IP address has been registered in your DNS sinkhole. TheHive displays the analyzer results as follows:

DNSSinkhole analyzer: long report
DNSSinkhole analyzer: short report

TalosReputation

This analyzer lets you determine whether an IP address has been reported as a threat on Cisco Talos Intelligence service. No special access to the service is required to run the analyzer.

TheHive displays the analyzer results as follows:

Talos Reputation: long report
Talos Reputation analyzer : short report

Crt.sh

This analyzer has been enriched to display SHA-1 fingerprints. The long report format has been updated to reflect this new information.

Crt.sh analyzer: long report

FileInfo

FileInfo has been updated and is now able to parse PDF files and extract IOCs such as URLs, hosts, domains, IPs, hashes and many more.The analyzer does also support the last version of the extract-msg library.

FileInfo analyzer: IOC Parser long report
FileInfo analyzer: IOC Parser short report

VirusTotal and Python3

The VirusTotal analyzer, including all its flavours, now uses Python3 and an updated virustotal-api library.

Yeti API key

An optional API key can now be configured and used by the Yeti analyzer.

Malwares_GetReport

A hash computation has been fixed in this analyzer.

EMLParser

A first fix has been introduced to avoid this analyzer to crash when there is no content-description in content_header, and a second has been added to correct a header display issue.

IBM XForce Lookup

The analyzer has been improved to allow users to add a trailing / at the end of the API URL without breaking everything.

Updating your Analyzers in Cortex 2.x

Each analyzer and responder comes with its own, pip compatible requirements.txt file. Run the following commands to update your Cortex analyzers to the latest version:

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

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

Dockerised Analyzers

Cortex 3.x gives you the opportunity to run dockerised analyzers and responders. This means that you no longer have to download all the git repository of Cortex-Analyzers and run lengthy commands to update your analyzers and responders.

If you want to use dockerised analyzers and responders, ensure that the URL of the catalog.json file corresponding to the Cortex-Analyzers repository is registered in application.conf. Please note that this won’t work if you are tracking the stable catalog.

After doing so, do not forget to login to Cortex as an orgadmin, click on the Refresh Analyzers button, then Disable and Enable again each analyzer and responder. Analyzer (and responder) updates should occur automatically as long as docker.autoUpdate is set to true in application.conf (this is the default setting).

Update TheHive Report Templates

If you are using TheHive, you must import the new report templates in your instance as follows:

  • 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

The Dead don’t Die

In December 2017, we published a fix for a nasty privilege escalation vulnerability, namely THP-SEC-ADV-2017-001.

On Tuesday May 21, 2019, it came back to bite us like a dead that doesn’t die when Adam Mariš reported it was still possible to do a privilege escalation in all versions of TheHive, including version 3.3.0.

After analysis, we found that THP-SEC-ADV-2017-001 did not address the full scope of the vulnerability. Adam hit the nail on the head – be like Adam! 👏

We have released a hotfix for the last version of TheHive which completely puts the dead to rest once and for all and we sincerely apologise for the issue.

What’s THP-SEC-ADV-2017-001?

The vulnerability allows users with read-only or read/write access to escalate their privileges and eventually become administrators. To exploit it, an attacker must have access to an account on TheHive with read-only or read/write privileges.

The attacker needs to interact with the API in a specific yet trivial way to obtain administrator privileges. After verifying that their request has been correctly processed, they connect to TheHive using the Web UI and they will see the administrator menu from where they can edit or lock user accounts, add case templates, etc.

And Now What?

We highly recommend you to update to TheHive 3.3.1 which completely fixes the vulnerability. If you are still using TheHive 2.x and have not made the move to TheHive 3 yet, please update to TheHive 2.13.4 which also addresses this flaw.

If you cannot immediately apply the hotfixes we have released, a shell script is still available and will allow you to spot anyone who exploited the vulnerability. You can download this script from the following location:

https://drive.google.com/file/d/1F8VOUMLoCVnIdHjnbhMTzf_9Z2Ud_Vuw/view?usp=sharing

The SHA256 hash of the script is:

18c74f921b92cc68ea7bc10c7522691d671074331191fe22269cc936bfdb0e9a

When you run the script, it will display all users that have changed their roles. If a single match is found, it means your  instance has been potentially compromised. We advise you to create a crontab which will execute the script on a regular basis until you apply the hotfixes.

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.

If you are using TheHive 3.x, upgrade to TheHive 3.3.1 by updating the binary package on your system.

On Spring, Bees and Cortex-Analyzers 1.16.0

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!

Release Overview

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?

Three analyzers have been added:

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.

FalconCustomIOC

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

An account and an API key is needed to configure and use this analyzer.

TheHive displays the analyzer results as follows:

AbuseIPDB: short report
AbuseIPDB: long report

BackscatterIO

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:

Backscatter.io:short report
Backscatter.io GetObservations: long report
Bascatter.io GetObservations: long report

SoltraEdge

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:

SoltraEdge: short report
SoltraEdge: long report

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

Cortex-Analyzers 1.15.3 get ready for URLhaus and Cuckoo

Few improvements have been introduced in this version :

  • Proofpoint analyzer has been updated to use python3 (#417)
  • Long report of Cuckoo Sandbox analyzer has been improved to be able to display Cuckoo v. 2.0.6 reports (#418)
  • URLhaus analyzer has also been updated to use the recently introduced API (#431)

On your Cortex server, update your analyzers with the following command:

$ cd /opt/Cortex-Analyzers && git pull
$ for I in analyzers/*/requirements.txt; do sudo -H /usr/bin/python2 -m pip install -r $I
$ for I in analyzers/*/requirements.txt; do sudo -H /usr/bin/python3 -m pip install -r $I

Updating analyzers should be followed by also updating report templates. Download new report templates and add the archive in TheHive report templates.

Detailed information

Cuckoo Sandbox

Thanks to @nicpenning Cuckoo analyzer is now able to display reports from version  2.0.6 of Cuckoo. With this version, remote connections part of the report has been fixed and is now well displayed

The new cuckoo analyzer template

Notice: This fix has been reviewed by our core team, unfortunately, we have not been able to test it.

URLhaus

Abuse.ch, the operator of URLhaus recently introduced a new API for their service in order to handle bulk queries and reduce costs for their main page that uses CDNs for delivery. Because of that, thanks to Nils Kuhnert, the URLhaus analyzer has been rewritten from scratch. Also, the templates changed because there are three different API endpoints used:

The short reports now display the threat type – which currently is always malware_download and, for the hash observable type, the malware family – if given by URLhaus:

Cortex-Analyzers 1.14.4 fixes an issue related to FileInfo

This new version fixes a major issue related to FileInfo analyzer following the update of library dependencies. It also enhanced short reports for Virustotal analyzer in order to well distinguish short report from GetReport and Scan flavors.

FileInfo

TL;DR

  • If you are a new user, you just have to follow  installation instructionsgit clone and install python libraries —
  • If you are using FileInfo and have an error message telling ModuleNotFoundError: No module named ‘ExtractMsg’ while running this analyzer, you can fix it by running following command lines :
sudo -H pip3 uninstall extract-msg
press y
sudo -H pip2 uninstall extract-msg
press y
sudo -H pip2 install git+https://github.com/mattgwwalker/msg-extractor.git@v0.19
sudo -H pip3  install  git+https://github.com/mattgwwalker/msg-extractor.git@v0.19

This will remove the latest version of msg-extractor library and install the last known working version with FileInfo analyzer.

Detailed information

To parse and analyze Outlook emails — msg files —, FileInfo analyzer uses a python library called msg-extractor written and published by @mattgwwalker. Few days ago, this library has been updated and includes some improvements that are not supported yet by FileInfo. Running this analyzer found in Cortex-Analyzer 1.14.3 and below with the latest version of the library will make your analyze never start and lead to the following error:

FileInfo_error_mesg
Error message after running FileInfo analyzer

We are currently working on FileInfo analyzer to be able to use the latest version of this really useful library.

In the meantime, and as a workaround, we force the usage of the last working version which is v0.19 in requirements.txt file of the analyzer. So if you recently proceed to the installation, updated this library and facing the error message, this can be fixed with the following operation:

sudo -H pip3 uninstall extract-msg
press y
sudo -H pip2 uninstall extract-msg
press y
sudo -H pip2 install git+https://github.com/mattgwwalker/msg-extractor.git@v0.19
sudo -H pip3 install git+https://github.com/mattgwwalker/msg-extractor.git@v0.19

Virustotal short reports

In order to well distinguish short report from Virustotal Scan and Virustotal GetReport analyzers we update short reports. This will display and look like the following screenshot:

sc-virustotal-short2
Virustotal: short reports

Cortex 101: Dissecting Observables a Hundred Ways

TheHive Project’s Code Chefs are glad to announce that, thanks to the precious contributions of the user community, Cortex has broken the one hundred analyzer mark.

Cortex-Analyzers version 1.14.0 is out and includes new analyzers, some improvements and some bug fixes.

New Analyzers

New and enhanced analyzers, described below, are:

  • Cisco Investigate by Cisco Umbrella Research @opendns
  • Proofpoint Forensics Lookup by Emmanuel Torquato
  • Proofpoint Threat Insight Forensics Analyzer by Emmanuel Torquato
  • RecordedFuture by jojoob
  • urlscan.io search by ninoseki
  • Google DNS over HTTP by 0xswitch
  • RTF files support in FileInfo by Nils Kuhnert
  • Datascan and Inetnum flavors in Onyphe analyzer by Pierre Baudry and Adrien Barchapt

Again, huge thanks for the awesome work that has been performed by all our contributors!

Investigate

Cisco Umbrella Investigate provides threat intelligence about domains and IP addresses accross the Internet. The analyzer can be used to query the Cisco Umbrella (formerly OpenDNS) API and get information about an IP or a domain name. An API key is required to use this analyzer.

Results are displayed in TheHive in the following manner:

sc-investigate-short

sc-investigate-long
Cisco Investigate: short and long reports

Proofpoint Forensics Lookup

According to Proofpoint’s website, the Forensics API allows insight in detailed forensic evidences about individual threats or compaigns. The analyzer can be used to check observables against given indicators of compromise stored in the ProofPoint service.

Unfortunately, there are currently no sample report screenshots available, because TheHive’s Core Team does not have access to Proofpoint services. Also, due to the same reason, this analyzer could not be tested by us. If you have access to the service and can test the analyzer and/or provide report screenshots, please let us know.

RecordedFuture

This analyzer lets you get the latest risk data from RecordedFuture for a hash, domain or an IP address. It can be used to query the API and get information. An API key is required to use this analyzer.

Results are displayed in TheHive in the following manner:

sc-recordedfuture-short

sc-recordedfuture-long
RecordedFuture: short and long reports

Urlscan.io search

Urlscan.io is a service that scans and analyzes websites. Submitted pages will be browsed like a regular user would do and every activity gets recorded. The analyzer submitted by ninoseki queries urlscan without initiating a scan which would be publicly visible on the website. Accepted datatypes for this analyzer are URL, domain, hash and IP.

The templates which display the results of the analyzer look like the following screenshots:

Screenshot from 2018-10-25 09-55-34

Screenshot from 2018-10-25 09-48-58
Urlscan.io: short and long reports

Google DNS over HTTP

Results are displayed in TheHive in the following manner:sc-googleDNS-short

sc-googleDNS-long
Google DNS: short and long reports

RTF files support in FileInfo

The FileInfo meta analyzer has been improved and now leverages the rtfobj tool provided in the Oletools suite by Decalage.

Results are displayed in TheHive in the following manner:

sc-fileinfo_RTF-short

sc-rtfobj-long
FileInfo with rtfobj: short and long reports

Datascan and Inetnum flavors in Onyphe analyzer

The Onyphe analyzer has been enhanced with two new flavors. Datascan provides information about known open ports on a specific IP, and Inetnum enumerates all known network information about the analyzed IP address.

An API key is required to use the analyzer and can be obtained by creating an account on the Onyphe website.

Results are displayed in TheHive in the following manner:

sc-onyphe-inetnum-short

sc-onyphe_inetnum-long
Onyphe  Inetnum: short and long reports

sc-onyphe_datascan-short

sc-onyphe_datascan-long
Onyphe Datascan: long and short reports
