Keylogger Github Android [upd] Today

When developing a keylogger for Android for ethical security research or educational purposes, you can draw inspiration from several advanced features found in prominent GitHub projects like StealthKeyLogger Pro PounceKeys Core Tracking Features Accessibility Service Integration

: Use Android's Accessibility Service to capture keystrokes globally across all apps without requiring a custom keyboard. This is a common method for modern Android keyloggers like PounceKeys Custom Input Method (IME) : Alternatively, build a custom software keyboard

that logs data as users type. This is often more reliable but requires the user to set it as their default keyboard. Screen Capture and Mouse Clicks

: Periodically capture screenshots or log touch coordinates to provide context for recorded keystrokes. Data Management & Exfiltration Secure Cloud Sync : Integrate with platforms like for real-time data storage and viewing through a secure dashboard Encrypted Transmission : Ensure all logged data is protected using AES-256 encryption during storage and during transmission to a remote server. Alternative Exfiltration Channels : Support multiple ways to send logs, such as via Discord bots , or direct IP buffers to avoid leaving trace files on the device. Offline Buffering Keylogger Github Android

: Store logs locally in an encrypted buffer if the device is offline and sync them automatically once a connection is restored. Stealth and Persistence App Icon Hiding

: Implement "stealth mode" where the application's launcher icon is hidden after the initial setup. Battery Optimization Bypass

: Request permissions to ignore battery optimizations so the logging service isn't killed by Android's background power management. Persistence Mechanisms : Use system intents (like BOOT_COMPLETED When developing a keylogger for Android for ethical

) to ensure the service restarts automatically when the device reboots. Ethical & Research Enhancements Temporal Analytics : Include time-stamping for all events to allow for time-based behavior analysis in security research. App-Specific Filtering

: Allow the researcher to choose which apps to monitor (e.g., only social media or banking apps) to limit data collection to relevant test cases. Anti-Debugging Studies

: For educational purposes, include (or study) techniques that detect if the device is being debugged or run in an emulator. For users: Regularly check Settings → Accessibility →

4. Evasion Techniques Observed in GitHub Repos

| Technique | Implementation | Target | |-----------|----------------|--------| | Permission hiding | Request SYSTEM_ALERT_WINDOW after installation, not during | User suspicion | | Encrypted exfiltration | AES-256 + HTTPS POST to C2 server | Network detection | | Delayed activation | Start logging 24h after install | Sandbox/emulator analysis | | Anti-uninstall | DeviceAdmin lock + hide from launcher | User removal | | Obfuscation | ProGuard + string encryption (XOR) | Static analysis |

One advanced repo (KeyRogue) uses native code (C++ via NDK) to hook libinput.so functions, bypassing Java-level detection hooks.

Title: Analysis of Android Keylogger Implementations on GitHub: Techniques, Evasion, and Defensive Strategies

5.3 Defensive Strategies

  • For users: Regularly check Settings → Accessibility → Installed services. Use Play Protect and a mobile EDR (e.g., Hypatia, Kaspersky).
  • For developers: Implement on-screen keyboard randomization for sensitive fields (e.g., custom PIN pad).
  • For Android platform: Google’s “Enhanced Confidentiality” mode (Android 14+) blocks AccessibilityService from reading sensitive fields (password, credit card).

Step 5: Obfuscation Techniques Found on GitHub

  • String Encryption: Log messages like "Sending keystrokes" are encrypted in the code.
  • Dynamic Class Loading: The malicious code is downloaded after installation to bypass static analysis.
  • Native Code (C++ via NDK): Logging logic moved to native libraries (.so files) to make reverse engineering harder.
