Technical Analysis of XBox Save Game Hack

Posted by CowboyNeal on from the picking-it-apart dept.

DJPenguin writes "There is an excellent article at the XBox Linux Project that describes exactly how the XBox savegame hack works. It details how the author went to great lengths to hide exactly what was going on. It turns out the exploit code is hidden within an image of Tux himself!" An enlightening read, to say the least.

  1. Stego or not? by robogun · · Score: 5, Insightful

    The code was "hidden" in the jfif header, therefore does not qualify as steganography in my opinion. But I bet MS jumps all over this and gets stego banned.

    The code is just brilliant. A lot of care was taken in the construction of this hack. No script kiddie is he.

    It looks like it retrives the private key. That's interesting.

    Napster-to-go says "Fill and refill your compatible MP3 player", which is a lie. It's not MP3. It's WMA with DRM.

    Nah, this is still just a buffer overflow. I doubt he "put" it in there.

    I think that any programmer can appreciate why he went to such lengths to hide the code. It's a hell of a cool thing to do.

    In this world of script kiddies, it's very important to disguinish between kiddies and people who are true hackers. Mad props to him for showing that hacking is most certainly an art.

    The modification of the public key to make is divisible by 3 was just beautiful.
