Crocodile Hunter is an EFF tool that detects fake 4G/LTE cell towers (IMSI catchers/stingrays) using software-defined radios like LimeSDR, USRP B200, and bladeRF. It listens to broadcast messages from nearby cell stations, infers their locations, and flags unusual activity via a web UI.
Use cases
- detect IMSI catchers in my area
- find stingray cell site simulators
- monitor for fake LTE base stations
- scan 4G towers for suspicious activity with an SDR
- run cellular surveillance detection on a Raspberry Pi
When to choose
- you have SDR hardware (LimeSDR, USRP B200, bladeRF) and need to detect cell site simulators
- you want an open-source, research-backed IMSI catcher detector with a web dashboard
When to avoid
- you need maintained or supported software - the project was archived in December 2022
- you lack SDR hardware or Linux (Ubuntu 20.04+) environment
- you need 5G detection - it only covers 4G/LTE
