DEF CON 33 - RF Village - Open Source Cellular Test Beds for the EFF Rayhunter - Ron Broberg
Rayhunter is an open source tool published by the Electronic Freedom Foundation which uses an Orbic RC400L mobile hotspot to detect potentially malicious cellular network data that may indicate a Stingray attack. In this presentation, we review the use of open sourced software cellular base stations such Open Air Interface 5G (OAI), srsRAN_4G, OpenBTS, and Yates GSM to create cellular test beds to robustly test the Rayhunter device and develop new detection capabilities.
