GNUCITIZEN is a Cutting-edge Ethical Hacker Outfit. We hack things for a living. To hack does not necessarily mean to crack into something illegally. We don’t do that! Not the illegal part. We get paid to hack, which is a hack on its own. As you will learn by reading our blog, hacking is mostly about finding creative solutions to interesting problems. Sometimes these problems are related to breaking into protected computer networks, sometimes they are related to other things such as influencing a large number of people to believe in made up values. Hacking is all about creativity or finding creative solutions to interesting problems. This is exactly what GNUCITIZEN stands behind.
