During yesterday's Why Silicon-Based Security is still that hard: Deconstructing Xbox 360 Security presentation at the 24th Chaos Communication Congress in Berlin, hackers Michael Steil and Felix Domke demonstrated a blown-wide-open hack for the Nintendo Wii. They've extracted the keys for signing Wii code, and now you can run anyone's code on your Wii, not just programs that Nintendo has sanctioned. Incredible as it may seem, there are still companies that think that they should have the right to tell you what you can and can't do with your hardware after you pay for it.
