MISP Guard

Let’s say that by no means should an attribute of type passport-number leave your MISP instance. Aside from the analyst following best practices when encoding the data, MISP does not have a built-in mechanism to prevent these leaks to happen, but now you can achieve this by using a third-party tool called misp-guard.

MISP web scraper

MISP web scraper

There are a lot of websites that regularly publish reports on new threats, campaigns or actors with useful indicators, references and context information. Unfortunately only a few publish information in an easily accessible and structured format, such as a MISP-feed. As a result, we often find ourself manually scraping these sites, and then copy-pasting this information in new MISP events. These tedious tasks are time-consuming and certainly not the most interesting aspect of CTI-work.

MISP 2.4.151 released (Black friday threat intel rush release)

MISP 2.4.151 released

MISP 2.4.151 released including a host of bug fixes and a bunch of new features

New features

• New background processor by @righel
• Improvements to the CLI tools
• Bug fixes and improvements

New background processor

• MISP has been using CakeResque for its background jobs for the better part of a decade. Whilst it has served us well, the library has been stale for a long time and carries a (for us) unnecessary complexity and is generally the most difficult part of the application to debug
• Luciano “@righel” Righetti has implemented a completely new, compatible background processing engine using Supervisord
• Queue and execute jobs the same way as you are used to from before, monitor worker progress via the tools provided by supervisord in addition to MISP
• No scheduling capabilities, these were an unnecessary overhead for us before as we relied on corn jobs as our preferred scheduling mechanism anyway
• Expect more improvements to this library over the course of the next months, but feel free to switch to using it already now
• Currently it is completely optional and the old background processor will still be supported for a while
• Be aware that manual setup steps are required to get the new processor working, refer to the upgrade guide on the procedure, if you decide to start using it already now

Various CLI changes

• Jakub Onderka has been doing a fair bit of refactoring and improvement of the CLI libraries
• additional administrative tools added to help monitor and manage your MISP instance (such as redis memory diagnostics, mysql table optimisation tool, etc)

Option to move the system settings to the database

• Traditionally all system config settings were stored in the config.php file, with a new configuration thanks to Jakub Onderka’s implementation the settings can be moved to the database rather than the file.
• This should help with persistence for containerised installations

Various improvements

• The previous version introduced a new STIX library as a replacement for the old one. This change did end up causing some update issues for some installations, the built in updater is now aware of this change and should allow you to easily update via the UI/API updater, with the new STIX library working as intended
• A long list of improvements, thanks to all contributors! For a detailed list of changes, head over to the changelog

MISP Modules

• New Passive SSH expansion expansion module.
• Updated Recorded Future expansion module included links and related data.
• New CIRCL hashlookup expansion module added.

The MISP modules changelog is available.

MISP 2.4.149 released

MISP 2.4.149 released including many bugs fixed along with some new and improved functionalities

New features

• First stage of a massive rework of our STIX integration
• Various improvements to the integration with Cerebrate

New STIX libraries

• The first version of a long ongoing project to rework our entire STIX integration has finally been merged, thanks to the tireless work of @chrisr3d
• Our converter libraries have embarked on a path of their own, becoming a standalone repository included by default in MISP, but also serving as a useful tool for anyone looking for a clean way of converting between the MISP standard format and various STIX versions (1.1.1, 1.2, 2.0, 2.1).
• The libraries are still work in progress, but continuously improved, follow misp-stix
• Included is also a detailed documentation, which also serves as a knowledge base for the mapping between the two formats, available under the documentation sub-directory
• From this release on, you have more control over which STIX version is used when exporting STIX data from MISP, by specifying the “stix_version” to be returned (supported versions for STIX 1: 1.1.1 and 1.2. For STIX 2: 2.0 and 2.1)

Cerebrate integration

• Allow the fetching of sharing group data from Cerebrate instances, our new open source tool in development aiming to solve a host of issues revolving around community management and orchestration. Our first official release of the tool is scheduled for the MISP summit coming up this month
• To follow the cerebrate project, head over to its github page
• For the MISP summit to be held on the 21st of October, don’t forget to watch the misp-summit. You can still apply for the Call-for-Presentation.
