An educational keylogger developed in Python to understand keystroke monitoring techniques, system-level interactions, and security implications. This project was created for cybersecurity research and educational purposes only.

🎯 Project Overview

This project demonstrates how keyloggers work at a technical level, providing insights into system security vulnerabilities and defensive measures. It showcases low-level system programming, event handling, and secure coding practices.

📚 Educational Objectives

• Understand keystroke capture mechanisms at the OS level • Learn about system-level programming and event hooks • Explore security implications of keylogging malware • Develop defensive strategies against such attacks • Practice responsible disclosure and ethical hacking principles

🔧 Technical Implementation

Core Features:

Keystroke Capture - Real-time monitoring of keyboard events • Event Logging - Secure storage of captured data • System Hooks - Integration with OS-level keyboard APIs • Stealth Operation - Understanding detection avoidance techniques • Data Export - Structured logging formats for analysis

Architecture:

The keylogger uses Python libraries to interface with system-level keyboard events: • Event listeners for capturing keystrokes • Buffer management for efficient data handling • File I/O operations for secure logging • Error handling and crash recovery

🛡️ Security Considerations

This project emphasizes understanding attack vectors to build better defenses:

Awareness - Understanding how keyloggers operate • Detection - Learning methods to identify keylogging software • Prevention - Implementing security measures against monitoring • Ethics - Emphasizing responsible use and legal implications

🔍 Defensive Insights

Through developing this project, I gained valuable knowledge about:

• How to detect keyloggers on systems • Security best practices for protection against monitoring • The importance of endpoint security solutions • Behavioral patterns that indicate keylogger presence
