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.

This talk from @wr is a masterpiece if you want to dive into all the gory details of the X.509 certificate format.
Seeing a presentation of the Kaitai project.
If you need to document or describe or decode binary format, Kaitai is clearly there to help.
An interesting lighting talk at #hacklu presenting a tool for Offline decryption of SCCM database secrets.
