As I wrote about a few days ago, I recently completed a massive overhaul of the SANS SEC587 Advanced OSINT course, including twenty new labs in 2024. One of the changes is a new wireless section, which includes a lab covering detecting modern drones using inexpensive USB dongles flashed with custom firmware.
Here is a short video I posted on YouTube showing how to identify the correct model of dongles on sites like eBay or AliExpress and how to flash the correct firmware step-by-step.
