Xbox 360 Kiosk Demo Spurs Hackers
An anonymous reader writes "Those hackers from team PI have released the Xbox 360 experience kiosk demo disc as an ISO. They say this demo contains no media protection and therefore it will run on the Xbox 360 when burned to a DVD-R disc. The disc contains playable demo's on the disk such as Call of Duty 2, which could also be hackable, as PI speculates."
Now they just have to figure out how the demo disk becomes playable, use it as a boot disk, and poof, free games for everyone. :) I might be buying a 360 sooner than I thought...
The executables as still signed. It is common for supporting data files to be un-signed. The executable usually does a hash check on its datafiles to make sure they haven't been messed with. It seems like everyone jumps on every little thing about the inner workings of the XBox 360 as a major exploit. The sensationalism is just getting boring.
Will someone here with a 360 and a spare half hour go get the aforementioned warez, and burn two copies - one with a single byte modified in one of the executable files?
Actual results posted here would be oh so welcome.

Urban Legend. Gamecube discs do not default to being read from the outside in -- depending on the game and manufacturer/producer of said game, the game's bootstrap code or loader or whatever you want to call it can be as far as 3/4 of the way to the end of the disc. But it still doesn't read from the outside in. It pops the end of the disc on boot to get the game's boot code, then hits back to the center like any other CD/DVD reading device.
To address the entire topic of this conversation, this 'achievement' doesn't mean crap. There is no *exploit* that allows this disc to boot. Whoever pressed it intentionally left off the media check -- thus allowing it to be played as downloaded from Live or on DVD. Not a big deal. It's still encrypted and signed -- the hypervisor still won't run it if a single bit has been altered.
I don't know about you, but I don't think my computer has enough spare CPU cycles in the next 100 years to crack the digital signing.
An exploit would be these people releasing the same DVD image that self-boots but has different content. But they can't. Because the 360 won't run it.
Just think about what people are inferring here. Microsoft, tremendous software goliath, pioneers new Xbox360 system that they claim is 'unhackable'. They have learned from their mistake with the Xbox and have actually taken many steps to make sure the system is as hard to hack as possible. 20 days after its release, they accidentally post an un-protected ISO on their website, allow production facilities to produce un-protected DVDs, and allow hackers to have full reign over their console.
Does this sound odd to anyone else? They wouldn't release these things if they didn't think (whether or not they're correct) that it had absolutely no gain to the hacker community. They're not going to help the hackers crack this system -- they have absolutely no gain from doing so. They lose money on each console, do you really think that's all they want you to buy? It doesn't work that way. This wouldn't have been released the way it was unless MS approved it -- there is a 99.95% chance that if they approved it, there is no way of hacking it.
I'd like to be proved wrong here, but until someone makes a DVD iso for the Xbox360 that opens up to a picture of a horse's ass and an arrow pointing to it that says 'SyncNine', I'm going to have to think I'm correct.
To the darkened skies once more, and ever onward.
