Summary: The Electronic Frontier Foundation (EFF) has launched Rayhunter, an open-source tool that detects cell-site simulators (CSS) like Stingrays, which impersonate cell towers to intercept sensitive information. Rayhunter captures control traffic without monitoring user activity and is designed for use on an affordable mobile hotspot device. This initiative empowers users to protect themselves against potential surveillance and helps illuminate the extent of Stingray deployments.
Affected: Individuals using mobile networks and potentially affected organizations.
Keypoints :
- Rayhunter detects suspicious network activity by analyzing control traffic between devices and cell towers.
- Unlike other detection methods, Rayhunter is accessible through an inexpensive mobile hotspot, enhancing user affordability.
- Users are alerted of potential Stingray attacks through a color change on the device’s screen, allowing access to detailed traffic logs for further investigation.
