Sentry Radio

Sentry Radio is a professional-grade Android forensic tool that detects, analyzes, and maps cellular network anomalies. It actively monitors dual SIM slots in real time to identify potential IMSI catchers, cell site simulators, and suspicious network downgrades.

I tested Sentry Radio while moving through different coverage zones to see how it handled sudden signal drops. Under the hood, it constantly checks physical and protocol layers for inconsistencies, instantly catching unrealistic power jumps. You get real peace of mind knowing the eBPF kernel filtering actually isolates your network during a panic event instead of just throwing a generic warning.

• Dynamic CVE scanning pulls live vulnerability data directly from the NIST NVD database, checking your specific modem against active threats.
• Advanced Panic Mode locks down your device during an emergency by severing network access and instantly disabling the radio hardware.
• Spotting fake towers happens automatically since the tool flags isolated cells lacking standard neighbor data.
• Full offline mapping plots your movement and detected cell sites using OSMDroid, making it easy to cross-reference data against databases like OpenCellID.

Support & Requirements

• Android Version: Android 10 (API 29) or higher.
• Root Requirement: Magisk or KernelSU are highly recommended for the baseband hardening module and logcat monitoring. LSPosed is optional but helps with package hiding and stealth.

How to Install

1. Download and install the Sentry Radio APK onto your rooted Android device.
2. Grant Superuser permissions when prompted and manually enable the "Display over other apps" permission for full-screen alerts.
3. Open the application, navigate to the Settings tab, and install the Sentry Hardening Module for direct system-level protection.
