Open Source Cellular Test Beds for the EFF Rayhunter
Ron Broberg
RF Village @ DEF CON 33 · Day 1 · RF Village
Ron Broberg's talk at RF Village, "Open Source Cellular Test Beds for the EFF Rayhunter," delves into the critical need for accessible, open-source tools to detect **IMSI catchers**, commonly known as Stingrays. Broberg, a seasoned professional from Darkworth Solutions with decades of experience at Lockheed Martin, highlights the pervasive and often invisible threat these devices pose to privacy and security. His presentation focuses on enabling security researchers and enthusiasts to build their own cellular test environments, thereby fostering a deeper understanding of cellular network vulnerabilities and empowering the development of detection mechanisms like the Electronic Frontier Foundation's (EFF) Ray Hunter project.
AI review
A competent, practically-minded RF Village talk that fills a genuine gap: giving researchers a legal, reproducible testbed for validating EFF Rayhunter without touching real Stingrays. The content is well-scoped for its venue and audience, but it's fundamentally integration work — stitching together known open-source stacks (srsRAN, OAI, YateBTS) rather than novel research — and the 'demo' is conceptual rather than live.
