The MISP galaxies and clusters are an easy way to add context to data. I’ve previously written an article “Creating a MISP Galaxy, 101” that describes how you can create your own galaxy and cluster.
Apart from the context, galaxies and clusters also allow you to describe relations between individual elements. These relations can for example be the synonyms (naming) for an APT group or the fact that a specific group uses a (MITRE ATT&CK) … Read more.
I published an article on the blog of the MISP project on how to create your own custom object: Creating a MISP Object, 101. This is a follow-up to a previous post on how to create your own MISP galaxy or MISP cluster (Creating a MISP Galaxy, 101).
MISP includes a powerful REST API that allows you to automate the dissemination of threat intelligence and threat data. If you aren’t familiar with the API you can explore its features (and the inline documentation) via Event Actions, REST client. In the latest versions of MISP the REST API client supports autocompletion, which is useful if you want to search for events or attributes with specific tags. And these tags are the vocabularies that we … Read more.

I run a couple of honeypots which allow me to map some of the bad actors and scanners on the internet. The most popular honeypots are Dioanea, Cowrie (ssh, previously kippo) and Conpot (ICS). So far I’ve not really used this honeypot data that much for defensive purposes but a recent writeup on using ModSecurity and MISP gave me inspiration to transform this data into information that I can use as a defender.
The core … Read more.
MISP sighting is a system allowing people to react on attributes on an event. It was originally designed to provide an easy method for users to tell when they see a given attribute, giving it more credibility. As such, the sighting system in MISP allows you to get feedback from your community on the quality of the data (the indicators).
There is not immediately an option within MISP to sync sightings between instances.You can sync … Read more.

Twitter is a great source for conducting open source intelligence. One of my favorite tools is Tweetsniff from Xavier Mertens. It will grab a Twitter user timeline for further processing, for example in Elasticsearch.
Another tool that I recently discovered is Tinfoleak. Tinfoleak is build for Twitter intelligence analysis and provides you with an HTML file output.
I wanted to use Tinfoleak to build profiles of users to tune targeted phishing campaigns (spear phishing) for … Read more.
