SafeScan - Spyware Detection App for IPV Victims

Overview

This app is designed to assist victims of Intimate Partner Violence (IPV), who feel unsafe using their devices. It provides a secure and comprehensive way to detect and manage potential spyware and privacy risks present on their devices.

Features

• Device Scan

  • App Detection: Scans all apps on the device and compares them against a predefined CSV file of dual-use and spyware applications.
  • Ranking System: Ranks apps from most harmful to least:
    • Red: Downloaded from an external location (off-store)
    • Yellow: Identified as pure spyware
    • Light Blue: Identified as dual-use (e.g., Location 360, and many parental control apps)
  • Secure Store Launch: Provides a button for each listed app to launch the secur store it was downloaded from.
  • In-Device Settings Link: Links to the in-device settings for each app so the user can check permissions.
  • Permission Risks: if an app has certain permissions activated, the app lists the risks of those permissions and provides recommendations on whether to keep them on or off.

Privacy Scan

• Google Privacy Checkup: Links to in-device Google privacy checkup settings.
• Social Media Settings: Links to the settings pages of popular social media apps installed on the device, with recommendations on which settings to deactivate for enhanced privacy.

ADB Feature

• Remote Scanning: Allows a source device (with the app installed) to connect remotely (via USB) to a target device.
• Data Output: Outputs all scan data from the target device to the source device.
• Risk Mitigation: Enables the victim to get help without having to download anything directly on their device, reducing the risk of alerting their abuser.

Technology Stack:

• Dart with Flutter: Primary development framework.
• Kotlin: Used for Android-side coding.
• Swift: In development for the iOS version of the app, with URL schemes generated for implementation.

Getting Started

• Close the repository: git clone https://github.com/BriLeighk/SafeScan.git
• Navigate to the project directory: cd SafeScan
• Install dependencies: flutter pub get
• Run the app: flutter run

Useful Commands

• adb devices: shell command that enables access to a connected Android device.
• adb tcpip 5555: shell command to enable tcp/ip on the network.
• adb shell ip -f inet addr show wlan0: shell command to get the IP address of the target device.
• adb connect <IP_ADDRESS>:5555: shell command to connect to the target device.
• adb shell pm list packages : shell command to get list of app packages from the device.
• flutter clean: clear the build cache.
• flutter build apk: build app apk for downloading the app.
• flutter intall: install app on specified device.

Attempting to Open Google's Privacy Checkup Directly

adb shell am start -n com.google.android.gms/com.google.android.gms.accountsettings.mg.ui.main.MainActivity Running this adb command causes the following error:

Starting: Intent { cmp=com.google.android.gms/.accountsettings.mg.ui.main.MainActivity }
Exception occurred while executing 'start':
java.lang.SecurityException: Permission Denial: starting Intent { flg=0x10000000 cmp=com.google.android.gms/.accountsettings.mg.ui.main.MainActivity } from null (pid=10507, uid=2000) not exported from uid 10212.

MainActivity for the in-device Google settings is not exported for external use: android:exported

ADB Connection Solution

Automate ADB Process and enable ADB over the network and connecting to the target device programmatically:

• Add ADB-OTG Library: handles ADB commands.
• Enable ADB over TCP/IP: Implement a method to enable ADB over TCP/IP on both target and source devices.
• Connect to Target Device: Implement a method to connect to the target device using its IP address (can be fetched both programmatically & manually by the user)

ADB-OTG Library

• Add to root build.gradle

dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

• Add dependency:

dependencies {
	        implementation 'com.github.KhunHtetzNaing:ADB-OTG:master'
	}
