Update Xbox 360 With Burned Cd-r

Why don't we just create a program to brute force the RSA encryption on the xbox 360, and have it run on our currently idle, or soon to be idle, xboxs?

That would put them to good use, heck maybe even run some wierd DX calls and have the GPU help the CPU out with calculations.  tongue.gif

Because if all the Xboxes that were ever made got together and had baby Xboxes, a thousand Xboxes each, and every single one of those Xboxes got to work brute forcing RSA, the sun would expand to a red giant and collapse, all the stars would grow dim, and the universe would fade to a featureless void before they were a minuscule fraction of a minuscule fraction of a minuscule fraction complete.

It was a joke!

Designated by the  tongue.gif

Anyway I originally had a disclaimer in small text in there, but the forums suddenly read the -7 size text as a gigantic font size, kinda the opposite of what I wanted.

i agree with your argument of course, however i don't agree on the bold claim of computers not being able to crack this code without millions of years. first of all, thats what clusters of computers can be used for, lets not talk in terms of a computer. plus also, when anybody makes such a claim, they seem to forget to take into account that computers do get faster, and there are more of them year upon year. of course, if anybody happens to have a cluster of supercomputers at their mercy, feel free to share.....

i'd also like to add that, if you have thought of some simple way to exploit some kind of loophole in order to run unsigned code, then MS have probably already thought of it, they did spend 2 years on the security for this machine.


yeah, one thing though. didn't Xbox-Linux make a supercomputer out of some Xboxes? Well as far as my knowledge goes, the xbox cpu is 128 bit processor, link some of these babies up and you got yourself something that might be able to decrypt the code *cough* in a couple of years *cough**cough*.

You're wrong, in too many particulars to list. I'm not gonna corrent you because I'm sick of correnting people who didn't bother to read the goddamn thread. Read my postings in this thread and General Technical and you'll understand how wrong you are.


I concur, the more you read about the 2048 bit key, the more you will understand that you have more chance of your XBOX 360 sprouting wings and flying south for the winter.

CPU: OK, 10^307 keys to go, jeez I been working on this for a million years already, GPU, can you give me a hand here?

GPU: Sure!!!  What do you want me to paint?

CPU: Ahem, paint???  Get your f***ing calculator out mate!

GPU: Calu-what?  I have all these pipelines, I suppose if you give me some matrices I can transform them into some amazing polygons for you?  Textured, bump mapped and everything?

CPU: No, I need you to help me with this b***ard of a sum, it's doing my head in!!!

GPU: What about some specularity light maps, I can produce some amazingly authentic HDR-L effects?  Maybe I can shed some light on the problem?

CPU: Never mind, I got more problems here now, I think part of my ALU just melted...  I just ran a thread that contained a posting from XBOX Scene forums, I happened to spot a string as it passed by, it read 'Why can't we brute force hack the XBOX 720s 8192 bit RSA key?'.   I think I am going to have a break down!!  Mediiiiiic!!

EDIT: PS - Yes, you can use GPU to do some calculations, but it's still not going to make sod all difference.

128bit??  It's a Pentium III 750!  32bit...

Sounds like the only way we will ever be able to make something and burn it on a disk to run in a default xbox360 would be to get ahold of the program at MS that signs these things.

sorry guys... it's been thought of... we tried to crack the first key to no avail... there was one project started... but I never heard of any success... and it would take an enormous amount of time to crack the key... so for now let's not even try and approach this method

It would be easier to go to the Xbox team at night and take a look in there....



You see, there is NO possibility of hacking Xbox 360 with Brute Force

totaly not xbox or xbox360 related.

but how did they do it in fact for the the dreamcast?

I have tried the selfboots but now, i ask my how did they do it.

can someone explain me how?
they boot directly from your dreamcast. did they find the key, i know they used a little sound track as raw file.
at the first track of the dics. but how did they find it? maybe i gone look i to it but it later but it's easyer to ask it here.

previous year i have seen the xbox-linux tool for the rsa key.
however did't know how it worked untill you guys explanatied it to me.

thx for the good info.

btw the dc stands for Dreamcast previous nick nigma at dcemulation know for the dc tonic cover at boob.co.uk tongue.gif shameless self promotion.  laugh.gif

you know what those hacker guys should do ?
Make a distributed calculation program, to brute force crack the private key of MS.

They should make something like that SETI@Home program. If like 10,000 people downloaded it, it would be cracked fairly quickly wouldnt it ?

NO.
This is the size of the number that must be factored. It is not feasible to do this in an acceptable amount of time even with all the computers on earth right now.

the key was designed with distrubuted computing, clustering, and supercomputers in mind, advancements in computer technology were also factored in

we will NEVER crack the private key this way
