Welcome!
I’m Koen . I live in Bruges (Belgium), a splendid medieval city also known as the Venice of the North.
I’m involved with computer security and I work as a freelancer in incident response, incident coordination, threat intelligence, vulnerability management and security best practices. Basically all tasks related to managing a CSIRT / CERT (Computer Emergency Response Team).
My main interests in computers are security, web applications (PHP, MySQL, Apache), system administration and free software.
This site hosts a blog and I have a photo collection at Flickr.

I shared the MISP playbook for malware triage that I regularly use for a first assessment on new samples. It uses MISP, VirusTotal, MalwareBazaar, Hashlookupand pefile. It then uploads the samples to MWDB and alerts to Mattermost.
The MISP playbook on malware triage is one of many playbooks that address common use-cases encountered by SOCs, CSIRTs or CTI teams to detect, react and analyse specific intelligence received by MISP.

The MISP2Sentinel integration allows you to sync indicators from MISP to Microsoft Sentinel. The old integration relied on the Microsoft Graph API.

Supports integration with the old Graph API, but also It supports the new, and preferred, Upload Indicators API.

In most MISP instances the database (MySQL or MariaDB) is on a local network, either directly on the machine or on a local DB-cluster. As a lot of organisations are moving towards a “full cloud” environment, this also means that they want to start making use of the database features offered by their cloud providers.
Microsoft offers Azure Database for MySQL and in this post I list the (limited) steps required to migrate the MISP … Read more.
