Brief

Rayhunter is presented as a low-cost, pocketable way to detect suspected cell-site simulator surveillance. The post frames it as an EFF-made open-source tool that runs on a cheap mobile hotspot and contrasts its roughly $20 price with older counter-surveillance setups that were far more expensive and technically demanding.

someone built a device that DETECTS when FEDS is SPYING on your phone nearby its called rayhunter, made by the EFF, and it costs $20 you buy a cheap mobile hotspot from amazon, flash it with their open source software, and carry it in your pocket feds use devices called stingrays that pretend to be real cell towers so your phone connects to them instead, once connected they can track your EXACT location, grab your phone identity, and potentially intercept your calls and messages counter-surveillance equipment used to cost THOUSANDS of $ and required serious technical knowledge now its $20 and fits in your pocket
