Thanks to its REST API and alerting framework, TheHive can receive alerts from multiple sources: email notifications, SIEMs, IDS/IPS and, of course, one or several MISP instances.
While the integration with MISP is native and very easy to configure, teams need to develop their own code to feed alerts from other sources to TheHive, leveraging whenever possible TheHive4Py, a very handy Python library to interact with the API.
If you are a TheHive user and a Digital Shadows customer, you can now fetch any incident or intel-incident raised by their Searchlight service using DigitalShadows2TH, a free, open source alert feeder for TheHive freshly cooked by your friendly and so Frenchy Chefs behind TheHive Project.
To use DigitalShadows2TH, you’ll need Python 3, the requests library and TheHive4py. You also need a Digital Shadows subscription and TheHive 2.13 or better with an account on your SIRP that can create alerts.
Please read the README file to learn how to install, configure and run this alert feeder.
It’s a sunny week in Paris, France (not Texas) barring the tropical rain that washed out the city earlier this morning. And when there’s sun in France, there’s happiness and… coding of course (what else?). The French Chefs of TheHive Project seem to be in a good mood (n’est-ce pas Jérôme ?), thanks to the vitamin D extra charge they got for free from the big star up above.
TheHive, Cortex and MISP work nicely together and if you’ve read our June-Dec 17 roadmap post, the integration of our products with the de facto threat sharing platform will get better in a few months.
During the FIRST conference presentation we gave last week, we displayed a picture that we will use here to try to explain how these three open source and free products integrate with one another.
TheHive is a Security Incident Response Platform (SIRP). It can receive alerts from different sources (SIEM, IDS, email. etc.) via its REST API. This is where alert feeders come into play.
Think of an alert feeder as a specialized program which consumes a security event (SIEM alert, email report, IDS alert, and so on), parses it and outputs an alert that its sends to TheHive through TheHive4py, the Python library we provide to interact with TheHive’s REST API.
We do not supply such feeders but developing them should be straightforward. If not, let us know and we’ll do our best to help you out.
Any alert sent to TheHive will show up in its Alerts pane. In addition to the sources mentioned above, new or updated MISP events will show up as well in that area if you configured TheHive to connect to one or several MISP instances. If so, TheHive will poll those MISP instance(s) at every interval looking for new or updated events. If there are any, TheHive will generate an alert which will end up in the Alerts pane.
Alerts can be ignored, mark as read, previewed and imported. When an alert is imported, it becomes a case that needs to be investigated.
A case can be generated from an alert or created from scratch. It is subdivided into tasks (think identification, containment, eradication, check proxy logs, and so on) and observables (IP addresses, hashes, email addresses, domain names, URLs…). When analysts are working on tasks, they add logs as they go. In TheHive’s terminology, logs are text entries which may contain attachments to help analysts record what they have been doing. Logs can be written using Markdown or a rich-text editor.
You don’t need to add the same tasks over and over when working on cases belonging to a given category (DDoS, Malspam, APT, …). You can create custom templates to which you add tasks as shown below. This is very useful when you are dealing with alerts so that when you import them, you can select which case template you’d like to apply and there you go!
Observables can be tagged, flagged as IOCs, and analyzed. When the investigation is well in progress or completed, you may want to share the resulting IOCs or a subset of those with partners and peers. TheHive will support the ability to export that data to MISP in September 2017. Until then, you can still export your IOCs as text, CSV or as a MISP-compatible format that you can use to add them to your MISP instance using the freetext editor. TheHive can export IOCs/observables in protected (hxxps://www[.]somewhere[.]com/) or unprotected mode.
Every observable must have a TLP (Traffic Light Protocol) level. By default, any added observable is considered TLP:AMBER. Please note that the TLP is taken into account by some analyzers. Wait! Analyzers?
Cortex is our standalone analysis engine and a perfect companion for TheHive and MISP. Analysts can use it to analyze observables using its Web UI, in which case they can be submitted only one at a time. The Web UI should really be limited to quick assessments of observables before creating a case in TheHive (or in an alternate SIRP). The power of Cortex really comes into play when you use its REST API. TheHive speaks natively to Cortex (as MISP does). Moreover, TheHive can leverage one or several Cortex servers.
An analyzer can be written in any programming language supported by Linux though all of our current analyzers are written in Python. This is because we provide a Python library called Cortexutils which contains a set of utility classes that make it easier to write an analyzer in Python.
Analyzers such as VirusTotal, PassiveTotal or DomainTools can provide different analysis services. Let’s take VirusTotal as an example. You can scan a file or URL. That’s one flavor. You can also obtain the latest available report on VirusTotal.com for a file, hash, domain or IP address. That’s a second flavor. So the VirusTotal analyzer has two flavors.
How about PassiveTotal? It has 8 flavors: unique resolutions lookup, SSL certificate history lookup, malware lookup, passive DNS lookup, data enrichment lookup, SSL certificate details lookup, OSINT lookup and WHOIS data lookup.
The MISP Search Analyzer
At this point, we need to mention a special analyzer that may create some confusion if not understood correctly: the MISP Search analyzer. Thanks to it, Cortex has the ability to search observables within a MISP instance as represented by the arrow that goes from the Analyzers to MISP.
When an observable is found in an event, Cortex will return the number of records found (i.e. the number of events where the observable has been found) and a list of links to those events with additional data.
The current version of the MISP Search analyzer can only search within a single MISP instance but in the near future, it will be able to support multiple ones.
MISP Expansion Modules
Besides its own analyzers (which include MISP Search described above), Cortex can also invoke MISP expansion modules. These are normally used by MISP to enrich attributes within events but Cortex can also take advantage of them to analyze observables.
There is some overlap between the native Cortex analyzers and MISP expansion modules. When choosing between a native analyzer or an expansion module, we highly recommend you select the former. The expansion modules are deactivated in the default Cortex configuration.
When you submit an observable for analysis, Cortex will create a job and, if successful, it will generate an analysis report in JSON format. TheHive has the ability to parse those results and present them in a human-friendly fashion thanks to report templates we offer for free. So when you’ll submit an observable to Cortex from TheHive, you’ll get back a short (or mini) report and a long one. The first can be thought of as a really tiny Exec Analyst Summary while the second provides more insight and details.
Calling Cortex from MISP
In addition to the expansion modules we have just mentioned, MISP 2.4.73 and up can enrich attributes using Cortex analyzers. The configuration is pretty straightforward. So if all you are concerned about is threat intelligence and sharing, you may augment your visibility into a given threat represented as a MISP event by leveraging all current 23 Cortex analyzers and any future ones.
TheHive, Cortex and MISP are three open source and free products that can highly aid you combat threats and keep the ‘monsters’ at bay.
TheHive, as a SIRP, allows you to investigate security incident swiftly in a collaborative manner. Several analysts can work simultaneously on tasks & cases . While cases can be created from scratch, TheHive can receive alerts from different sources thanks to alert feeders which consume security events generated by multiple sources and feed them into TheHive using TheHive4py Python library. TheHive can also sync to one or several MISP instances to receive new and updated events which will appear in the alert pane with all the other alerts generated by other sources. Analysts can then preview new alerts to decide whether they need to be acted upon. If so, they can transform them into investigation cases using templates.
To analyze the observables collected in the course of an investigation and/or imported from a MISP event, TheHive can rely on one or several Cortex analysis engines. Cortex is another standalone product that we have developed which sole purpose is to allow you to analyze observables at scale thanks to its large number of analyzers, MISP expansion modules and any analyzer you might have developed on the side. Cortex has a REST API that can be used to empower other security products such as ‘analytics’ software, alternate SIRPs or MISP.
The highly popular threat sharing platform can indeed enrich attributes thanks to Cortex as it has a native integration with it. And in a few months, you will also be able to export cases from TheHive as MISP events that you can share with peers and partners.
If you do share, you do care about our collective mission to defend thedigital assets that are under our watch from harm. So let us fight together as one.
TheHive Project French chefs are very excited to announce the immediate availability of Mellifera, TheHive 2.11.0, the greatest and latest iteration of our flagship product.
We are thrilled to share this major version with the incident response community, for free as usual. Yes, you read that sentence right. You don’t have to cough up a single € or BTC for a platform that is as good as some commercial alternatives, unless your boss is hassling you about paying big bucks to get so-called professional support. If that’s the case, try us and you might prove them wrong.
Going through all the features and fixes of this significant overhaul will take forever (well, almost) so let us highlight a few that we feel worthy of your attention and time.
The Alerting Framework
If you need one reason to upgrade from Buckfast to Mellifera or to ditch your existing, clunky incident handling platform and use ours, then that should be its brand-new and powerful alerting framework.
With Buckfast (TheHive 2.10.x) and earlier versions, you can configure multiple MISP instances. TheHive will then poll those instances at regular intervals and display new or updated events in a specific area where analysts can preview them, import them as cases using configurable templates or ignore them altogether (and if they do so by mistake, there’s no way to go back). And if you needed to raise alerts from a SIEM, email reports or other sources of noteworthy security events, you had to rely on TheHive4py API client and create a case without having a chance to preview the events in TheHive prior to the case creation.
Mellifera does not have these limitations. It features an all new, fancy and efficient alerting framework which can be displayed using the Alerts button in the Web interface. This button was previously called MISP.
Within the Alerts area, you can preview not only new or updated MISP events but also any event that you have pushed through TheHive4py. The client has been modified to be compatible with Mellifera. If you have an existing TheHive4py package, please upgrade to the new 1.2.0 version using PIP.
Using TheHive4py 1.2.0, you can send your SIEM alerts, user email reports and security events from various sources to Mellifera and your analysts will be able to preview and import them or simply ignore them. If they have ignored some events by mistake, they can use the quick actions on the top of the panel to retrieve them. Please note that you have to create programs that will bridge your event sources with Mellifera through TheHive4py.
All New Skin
Mellifera has an all new skin with many refinements spread all over the interface. For example, you can now easily reorder the tasks within a case template. You can also sort task logs according to their creation date (oldest first, newest first). The flow (a.k.a live stream) is also collapsible. Moreover, when you create a case, Mellifera will suggest existing tags.
Is MISP or Cortex There?
If you have configured Mellifera to interact with at least one MISP or Cortex instance, the Web interface will show their respective logos at the bottom of the page. Please note that you can now connect to MISP and Cortex even if you are behind a proxy which requires authentication.
New Installation Packages
Starting from this release, we no longer produce all-in-one binary packages and dockers containing TheHive and Cortex. Instead you can use dockers, binaries and RPM as well as DEB packages. Wink wink.
One More Thing
Mellifera has an all new logo and the project website has been completely redesigned. Now you can see who’s behind the project thanks to Alexandre Gohier, a close friend who also happens to be a professional photographer.
