Is ICE about to go buck wild using cell site simulators? Good thing EFF has a project to help you detect them:

Meet Rayhunter: A New Open Source Tool from EFF to Detect Cellular Spying

Rayhunter is a new open source tool we’ve created that runs off an affordable mobile hotspot that we hope empowers everyone, regardless of technical skill, to help search out cell-site simulators (CSS) around the world.

@evacide RayHunter uses inexpensive hardware and is not difficult to set up. $20 and a little following pretty well written directions, and you are ready to detect the “stingray” devices.

@WackyIdeas @evacide I couldn't find the FAQ. If I want to join (outside the US), do I need to get a SIM card for this? How much data would it use per month?
