Testing Android Intents for Vulnerabilities

When to Use

Use this skill when:

• Assessing Android app exported activities, services, receivers, and content providers
• Testing for intent injection and unauthorized component invocation
• Evaluating broadcast receiver security for sensitive data exposure
• Performing IPC-focused penetration testing on Android applications

Do not use on production devices without explicit authorization.

Prerequisites

• Rooted Android device or emulator with ADB
• Drozer agent installed on target device (drozer agent.apk)
• Drozer console on host (pip install drozer)
• Target APK decompiled with apktool for AndroidManifest.xml analysis
• Frida for runtime intent monitoring

Workflow

Step 1: Enumerate Exported Components

# Using Drozer
drozer console connect
run app.package.info -a com.target.app
run app.package.attacksurface com.target.app

# Output shows:
# X activities exported
# X broadcast receivers exported
# X content providers exported
# X services exported

# List exported activities
run app.activity.info -a com.target.app

# List exported services
run app.service.info -a com.target.app

# List exported receivers
run app.broadcast.info -a com.target.app

# List content providers
run app.provider.info -a com.target.app

Step 2: Test Exported Activities

# Launch exported activities directly
run app.activity.start --component com.target.app com.target.app.AdminActivity

# Launch with intent extras
run app.activity.start --component com.target.app com.target.app.ProfileActivity \
  --extra string user_id 1337

# Test intent injection via data URI
adb shell am start -a android.intent.action.VIEW \
  -d "content://com.target.app/users/admin" com.target.app
