Cross-Platform Keylogger

This project is a system-wide keylogger that works across multiple platforms: Windows, Linux, and macOS. It captures keystrokes and logs them to a text file (keystrokes.txt). The code demonstrates how to interact with low-level keyboard events on each operating system to capture key presses.

Features

• Supports Windows, Linux, and macOS.
• Logs keystrokes to a file (keystrokes.txt).
• Windows version uses SetWindowsHookEx to capture keyboard events.
• Linux version uses /dev/input to capture key presses from the keyboard device.
• macOS version uses CGEventTap to intercept keyboard events.

Requirements

For Windows:

• Windows OS.
• A C compiler like GCC or MSVC.
• Necessary permissions to run the keylogger (e.g., administrator privileges).

For Linux:

• Linux OS (tested on Ubuntu).
• A C compiler like GCC.
• Root permissions to access the keyboard event file (/dev/input/by-path/platform-i8042-serio-0-event-kbd).

For macOS:

• macOS OS.
• Permissions to access system events (e.g., Accessibility or Full Disk Access permissions).

Important Notes

• Ethical Use: This keylogger is intended for educational and research purposes only. Do not use this tool for malicious activities.
• Legal Considerations: Unauthorized use of keyloggers is illegal and unethical. Always obtain explicit consent from individuals before capturing keystrokes.
• Permissions:
  • On Linux, Windows, and macOS, the program may require elevated permissions to access the keyboard device or system events.
  • Ensure that you have the necessary permissions before running the keylogger.
