Rust Keylogger

⚠️ This project is intended strictly for educational and detection testing purposes. Do not use in any real-world environment without explicit authorization.

Overview

This is a simple keylogger written in Rust using the rdev crate. It captures key presses and logs them to a file.

Features

• Captures global key presses
• Logs keys to keylog.txt
• Works on Linux, macOS, and Windows (with proper permissions)

Requirements

• Rust (https://rustup.rs)
• Permissions to access keyboard events:
  • macOS: Enable accessibility permissions
  • Linux: Requires X11
  • Windows: May require administrator privileges

Installation

git clone https://github.com/Sn0wAlice/rust-keylogger
cd rust-keylogger
cargo build --release

Usage

cargo run --release

This will start listening for key presses and save them to keylog.txt.

Detection Tips for SIEM

Use this tool to generate telemetry and validate detection strategies:

• Monitor access to rdev, X11, or SetWindowsHookEx APIs
• Watch for processes writing to files like keylog.txt outside standard paths
• Look for CLI apps without GUI accessing keyboard input
• Detect Rust-based binaries hooking into keyboard events
