SafeScan - Spyware Detection Tool

Overview

SafeScan utilizes ADB-OTG and extends its functionality to create a comprehensive spyware detection tool. The project aims to assist victims of Intimate Partner Violence (IPV) by providing a secure way to detect and manage potential spyware and privacy risks on their devices.

Project Evolution

This repository builds upon the original SafeScan project, which provided comprehensive app and privacy scanning for source devices. The current version extends these capabilities by:

• Integrating ADB functionality for target device scanning
• Maintaining consistent connection state across the application
• Implementing modular feature migration from the original SafeScan
• Enhancing security and reliability for dual-device operations

Key Features

Completed Features

• Device Connection

  • USB OTG connection between devices without requiring root access
  • ADB command execution from source to target device
  • Device selection dropdown for managing source/target operations

• App Detection

  • Scanning of installed applications against known spyware/dual-use app database
  • Risk categorization system:
    • Red: Off-store downloads (highest risk)
    • Yellow: Known spyware applications
    • Light Blue: Dual-use applications (potential for misuse)
  • Integration with remote CSV database for up-to-date threat detection

• User Interface

  • Clean, intuitive interface for both technical and non-technical users
  • Clear visual indicators for connection status and scan results
  • Informative permission descriptions and privacy recommendations

In Development

• High Priority

• App icon retrieval for detected applications
• Comprehensive permission analysis for detected applications
• Direct Android settings access for listed applications
• ADB connection stability improvements
• Global ADB connection state management

• Upcoming Features

• Privacy Scan implementation (migration from original SafeScan)
  • Device privacy settings analysis
  • Social media privacy recommendations
  • Google account security checkup
• Target device support for privacy scanning

• Note: The Privacy Scan feature from the original SafeScan repository is currently not implemented in this version. The Privacy Scan tab exists in the interface but is non-functional until the feature migration is complete.
