Android App for Mobile Network Security

A new app called SnoopSnitch can detect International Mobile Subscriber Identity (IMSI) catchers by keeping a tab if someone is spying on you.
IMSI catchers are eavesdropping devices used for intercepting mobile phone traffic and tracking the movement of smartphone users, media reports said.The app scans for signals that indicate a switch from a legitimate tower to a 'stingray', where information may be being collected.
The following permissions are required:

• ACCESS_SUPERUSER: Open Qualcomm diagnosis interface to capture radio data

• CALL_PHONE, READ_PHONE_STATE, SEND_SMS, RECEIVE_SMS: Generate mobile network traffic recorded in active tests

• GET_TASKS: Retrieve state of helper processes interacting with diagnosis interface

• WAKE_LOCK: Acquire CPU for long-running analysis steps

• ACCESS_FINE_LOCATION, ACCESS_COARSE_LOCATION: record location of IMSI catchers and security events if configured

• INTERNET: Download new data from gsmmap.org, upload radio traces and debug logs upon request

•  ACCESS_NETWORK_STATE: Postpone uploads until network is available.

* To use SnoopSnitch, a rooted device with a Qualcomm chipset running stock Android 4.1 or higher is required.
