keylogger-osx

This is a very simple keylogger for self-quantifying. The source code is awfully dirty, but it works for me and that's enough.

Story

My friend and I were discussing about the Carpal Tunnel Syndrome. He asked how many keystrokes I perform everyday, and I totally had no idea. However, keystrokes are highly sensitive information and I don't trust those softwares in the wild.

Being a programmer, simply write one by myself. That's it.

Usage

Build the code and deploy it to /usr/local/sbin/. Then drop the Launchd script to /System/Library/LaunchDaemons to fire up this keylogger on startup. By default, the keystrokes would be logged in /var/log/keystroke.log. You may need root priviledge when writting to /var/log/.

Remember to check Enable access for assitive devices in the Universal Access preferences panel.
