Current state of the MISP playbooks

I published an overview of the current state of the MISP playbooks, covering the work that has been done in 2023 and the features you can expect in 2024.

Activity 4: MISP workflow integration, Elasticsearch, MDTI and support for curation Activity 5: Timesketch, conversions with CACAO and Microsoft Sentinel Activity 6: Scheduled playbooks, timelines,

MISP playbook: Malware triage

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.

ENISA Threat Landscape 2023

I contributed to the ENISA Threat Landscape 2023.

The ETL is an annual report on the status of the cybersecurity threat landscape. It identifies the top threats, major trends observed with respect to threats, threat actors and attack techniques, as well as impact and motivation analysis. It also describes relevant mitigation measures.

In the latter part of 2022 and the first half of 2023, the cybersecurity landscape witnessed a significant increase in both the varietyRead more.

MISP to Microsoft Sentinel integration with Upload Indicators API

The MISP2Sentinel integration allows you to sync indicators from MISP to Microsoft Sentinel. The old integration relied on the Microsoft Graph API. Microsoft prefers new integrations to rely on the Upload Indicators API. The new MISP to Microsoft (previously Azure) Sentinel or misp2sentinel does just that, it

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

MISP to Sentinel integration

I published a blog article on the MISP project website on how to do the MISP to Azure / Sentinel integration. This integration allows you to upload indicators from MISP to Microsoft Sentinel. It relies on PyMISP to get indicators from MISP and an Azure App and Threat Intelligence Data Connector in Azure.

The integration is available via GitHub at https://github.com/cudeso/misp2sentinel

Migrating your MISP database from a local MySQL to Azure Database for MySQL

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 MISPRead more.

Include threat information from MISP in Zeek network visibility

Zeek (formerly Bro) is a free and open-source software network analysis framework. It gives insights on DNS queries, HTTP and TLS information and details on transmitted files. I find Zeek one of the best network monitoring tools available to provide detailed visibility on network traffic.

Zeek has a built-in intelligence framework. This framework allows you to add information received via MISP directly into the network visibility capabilities of Zeek. This includes

CTI-Summit 2022 Luxembourg Presentations

The first edition of the Cyber Threat Intelligence Summit took place in Luxembourg in October 2022. I did two presentations:

One presentation on MISP web scraper, a tool to create MISP events and reports from scraped websites; and one presentation on building CTI Operational Procedures with Jupyter Notebooks and PyMISP.

The slides and recording are available on GitHub and Youtube.
