Android IMSI Catcher Detector
This project is a mobile network security auditor and IMSI catcher detector designed to identify fake base stations and surveillance hardware attempting to intercept mobile traffic. It functions as a radio interface analyzer and cellular tower mapping tool, monitoring connections to detect unauthorized network infrastructure.
The system distinguishes itself by combining real-time threat level monitoring with the ability to identify silent SMS and stealth communications used for device tracking. It analyzes ciphering status to detect forced network downgrades to weaker encryption standards and verifies base station identities by cross-referencing tower data against public databases.
The tool covers broad capabilities in mobile network auditing, including signal anomaly tracking, radio hardware data extraction, and the prevention of remote SIM-based attacks or unauthorized application installations. It further provides tower connectivity visualization and a mechanism for users to define custom detection strings for monitoring suspicious messages.
Low-level hardware interaction is achieved by executing AT commands via a root terminal to retrieve detailed network telemetry.
