Ron Gonggrijp about KPN: "The most important thing about hacking is the 'mindframe' you have when looking around you. There's a lot of things wrong with the technology we trust so much. When the Dutch Telecoms bring a new invention on the market, like the digital telephone, we are the first to show the flaws in the system. You would never get this kind of information from big corporations. Never, never take what is written in the users manual for granted is another of our paroles. Hack it. And only then you'll know how secure it is. The whole world around us is fast changing into systems. It is important that we learn to think about it for ourselves, and not to trust blindly that small self-appointed elite that allegedly knows-it-all."
