The MISP Galaxy now includes an updated knowledge base of UAVs and drones covering both civilian and military models.

It comes with detailed attributes such as manufacturer, cost, and technical specs.
You can now easily classify, model, and share UAV-related observations directly in MISP.

One year, I had a chat with the fine people @suricata during the @cert_eu conference, and they were wondering why we didn't create an open source website for all the different rules (YARA, Suricata, and many others) — a place to allow comments, reviews, bundling, and integration with @misp.

We’ve just released the first beta version of the rulezet.org service! 🎉

The platform is open and publicly available and the entire back-end is fully open source.

It’s still in beta, so feedback is very welcome!
