I wanted to share a security flaw I discovered on xbox 360 while playing a game.
Since I play mostly single player games and I don't have a gold membership at the moment, I configured my 360 not to connect to xbox live on startup and I also have a button pattern that stops unauthorized access to xbox live.
Today I decided to play a bit of battleblock theater and when I started the game it said that it nedded to connect to xbox live and I said ok. But it connected automaticaly overriding the security of the button pattern.
Here is a video I filmed of what I am saying: http://videobam.com/oFNfd
