Bruteforce Cpu Key Possible?
« on: May 15, 2010, 11:42:00 AM »

This might be a stupid post and i haven't seen anyone talk about this so here's the idea. Since its not feasible to flash a dvd drive over and over again to try to get the right key, that would take forever. My idea is to dump the nand (or atleast the raw kv) and then try to open it up with 360 flash dump tool or whichever tool allows you to see the kv except since we don't have the CPU key make a whole new program or add a function to the app so that it will brute force the CPU key until it gets a real result from the keyvault. I hope this makes sense to anyone and anyone with experience i'd love to here input, I believe this would be very realistic and bruteforcing on even a slow computer couldn't take horribly long (look at jack the ripper and how many passwords it can attempt per minute). Anyways I hope this isn't just a pipe dream and with some help I can code an app to do this (that way anyone who buys a 360 and doesn't have dvd key they could atleast hook up an lpt/usb cable to 360-computer, get keyvault, crack keyvault and then you atleast know your DVD key and OSIG (among other things).  Thank you for your time.

Sure it's possible, but it's unlikely to be finished in our lifetime.  I believe there are something like 18 billion trillion possibilities, so good luck  (IMG:style_emoticons/default/wink.gif)

Thats for dvd keys i believe cpu keys even if it is a real high amount a ps3 running linux (with the cell processor) could bruteforce quickly enough (if i coded a linux app) that worst case scenario it takes a day or 2 to brute force it but if it worked it would turn so many consoles that people get screwed on (or screwed up their drive) and don't have key...and get their console working again...i'm sure all the people that have consoles without dvd key's wouldn't mind waiting a day or two while their computer brute forces the cpu key...also i thought the cpu key was only in hex...ie only chars possible in cpu key are 0-9 and a-f . Anyone know if that is correct? I've not seen a cpu key with a letter higher than F. Anyone have any input on CPU key characters (not dvd even tho i think dvd key has same char limits).
Thanks for the advice so far but this is a feasible thing then i'm guessing?

No this has been discussed before and on many occasions. There was a thread about a half year ago that went into great detail as to why it would take many hundreds of years to accomplish such a task.

It would be quicker to wait a few years in hopes that another JTAg type exploit can be discovered with the newer kernels.
