Hacker claimt hoofdprijs kraakwedstrijd Xbox

Nou ja tis wel knap hoor....

Ik ben benieuwd of Microsoft hier nog een reactie op gaat geven. Het lijkt mij dat ze niet op deze resultaten zitten te wachten.

[edit] Praktisch hetzelfde als mijn bovenbuurman heeft geschreven

We have looked at this exploit and have drawn a few conclusions. We are fairly sure he is NOT running unsigned code. Looking at the patch file he applies to the linux xbe, we are concluding he is changing the hash and signature portions of the xbe. We changed a byte in that signature and this exploit no longer worked. Thus we can conclude he is not running code independent of the signature. We believe the save game exploit somehow allows him to change the signature scheme, not sure how quite yet, but then executes code that he has been able to self sign based on his exploit of the signature.mostly likely, he modified the public key and left the signature system alone

We will be building on Habibi_xbox's work and releasing more ways to run Linux on your unmodified Xbox.

This represents the first confirmed success in the Project B competition, which runs until December 31st 2003. As it is still not possible to use this exploit purely from HDD or USB dongle on an unmodded box (you must use a retail DVD of "007 Agent Under Fire" only), we hope this won't be the last great Project B entry we see.
>> This news is a follow-up to the topic on the xboxhacker.net forums (here) about someone that claims he managed to run linux live on a non-modded xbox using an exploit in the save handling. At this moment we can't confirm if it's true or not (I don't own 007).
You can discuss this in our forums here

The post on the XBH forums contained an incorrect uu file , we received the correct uuencode from an anonymous source. (that will produce a working zipfile - unzip tested successfully):

Ladies and Gentlemen,

I'm happy to present the first solution found for the Xbox Linux Project B:
Here is a way to run Xbox Linux on an unmodded, unopened Xbox !

Inlcuded is a uuencoded zip file containing all the necessary files. Here is
what you need:

- - You need an unmodded XBOX (not sure it works with modded bios)
- - You need the game 007 Agent Under Fire (*NOT* NIGHTFIRE, those are two different games!)
- - You need a way to transfer a save to a memory card (that is, xbox-save.com's hardware, or usb<>xbox cable + usb stick + xbox-save software, or you can use a standard memory card too if you can put files on it (with EvoX for instance).
- - You need to get the "Xbox Linux Live" small distro.

Got all this? Let's party!

- - Unzip 007linux.zip
- - Extract the Xbox Linux Live ISO with a STANDARD ISO extractor (ie WinISO)
- - Copy the Xbox Linux Live files into the UDATA\4541000d\000000000000\ directory (including "boot" subdirectory) (don't copy the file "plugin.img" or it won't fit on a standard memory card).
- - Now, replace the first 0x380 bytes of the default.xbe with the 0x380 bytes contained in the "default.patch" from the included zip file
- - Copy the whole 4541000d directory to your memory card (starting from 4541000d, not UDATA. UDATA directory is here so it works with xbox-save.com's software)
- - Use the Xbox Dashboard to copy the 007 save from the memorycard to the HD
- - Run 007 on the Xbox
- - In main menu choose "Load Mission", then "Xbox Hard Disk"
- - Et Voila ;-) If things went well you should get a Black Screen, and Xbox LED turning to orange (this is done when linux kernel is loaded), and after a couple of seconds you should heard the Xbox Live Linux "loading sounds"

Just take this as a "proof of concept", there won't be anything on screen because video has to be initialised in Linux like it is in Xromwell, but as there is no "official version" of Xromwell I found, I prefer to use Xbox Linux Live as example as everybody can find it.

Basically there is a bug in the save handling, which has been found in several games, I just took 007 because only one save is needed for both US and PAL game version - for other games you usually need two (or even more).
More explanations on how it works, how to make other linux distro work and GPL sourcecode will follow!

I'm already anticipating some questions:

Q: Will it run my backup games without a modchip ?
A: No, it won't. This trick works for running Xbox Linux ONLY.

Q: Is it real?
A: YES.

Q: What if MS removes 007 Agent Under Fire from the shelves now ?
A: 007 Agent Under Fire is just one of the several games with this bug, so don't worry :-)

Enjoy!
Will.

Use uudecode to extract the following file, or copy/paste it to 007linux.uu and load it with WinZip.

Als je de openings post goed las, is het een XBOX die niet veranderd is,... qua Mod-Chips of HD´s...

Ok, maar hij bedoelde : De XBOX is gewoon een PC, en daar kan niemand hem ongelijk in geven.
