This article is an informational writeup from the MISP Project describing outcomes of the JTAN (Joint Threat Analysis Network) initiative, co-funded by the European Union's CEF program. It is not a threat report but a technical/process overview of data-sharing mechanisms tested for CSIRT and SOC networks, including MISP synchronization, MISP caching, MISP's REST API, real-time streaming via CocktailParty and N6, and privacy-preserving techniques using PSS (peer-to-peer search) and Bloom Filters.
The goal of JTAN is to improve interoperability and situational awareness among European national CSIRTs by strengthening and interconnecting existing CTI tooling, rather than introducing new detection capabilities or responding to a specific threat. The document serves as a reference for organizations seeking to build or improve threat intelligence sharing infrastructure using open-source tools compatible with the MISP standard.
There is no indication of active exploitation, malware, threat actors, or vulnerabilities in this piece — it is purely a project/process report on tooling and collaboration frameworks for the CSIRT community.

Free public brief. Slack alerts on the vendors you run come with the paid plans, and a new account gets three days of them, no card.
What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the campaigns it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
