Crocodile Hunter is a tool to hunt fake eNodeBs, also known commonly as hailstorm, stingray, cell site simulators, or IMSI catchers. It works by listening for broadcast messages from all of the 4G stations in the area, inferring their location, and looking for unusual activity.
This repository is part of an EFF project studying the newest generation (i.e. 4G/LTE) of Cell Site Simulators. We recommend you read our guide to IMSI Catchers: Gotta Catch 'Em All.
The main project is located in
/src and is based off of srsLTE and our setup has been tested and is known to work on the Lime SDR, USRP B200, and the bladeRF x40, but should work with any hardware supported by srsLTE.
For a complete list of necessary hardware check out our hardware guide.
Crocodile hunter works best on ubuntu 20.04 or later. On intel/amd based systems (most laptops) you can simply run the following command to get started:
Before you run this command we reccomend getting all of the hardware in place and a Wigle.net api key.
