Catching the Catchers: Open Source Stingray Detection in the Wild
Cell-site simulators (CSS), also known as Stingrays, are surveillance devices that impersonate legitimate cell towers, forcing nearby phones to connect. They can track devices, harvest IMSIs, and in some cases intercept communications, all while operating in secrecy. Despite their widespread use, little is publicly known about how or where they are deployed. Rayhunter, developed by the Electronic Frontier Foundation (EFF), is an open-source tool that puts CSS detection into the hands of everyone. Running on an inexpensive Orbic mobile hotspot, Rayhunter passively monitors cellular control traffic to identify suspicious behavior. This talk will explore how Rayhunter works, why it fills a critical gap left by existing detection methods, and what early deployments are revealing.
