I suggest you learn the subject we're discussing - then reply. Mitnick would very much agree with me - since people aren't involved. We're talking plain crypto here.
160 bit DES is well over "not even if all atoms in the universe were parallell supercomputers would they've searched the keyspace since the beginning of time" limit.
(Depending on if I have to be at work the next month I'm going to seriously look into external mods for the Xbox. There are two stacks worthy of probeing.. )
I've used PKCrack, there seems to be other programs using the same method. What it does is to use 11 (or is it 14, my memory might be off here) known cleartext bytes - you almost always have these since most filetypes have known headers - and then bruteforce the 3 different 32-bit keys. 32 bits is nothing - you should be able to decrypt the archive within an hour.
(There's an interesting story behind how this hack was achieved the first time around - it involves fake pirate Sky 0a satellitecard files.. )
These kind of keys are never available in the clear. A purpose-built "black box" has the key inside it, with no way of extracting it even if you work at Microsoft.
Andy, of course it helps Lindows. The patches done to get Debian (and Mandrake) running on the Xbox are virtually the same needed to get Lindows running.
The real problem with the whole idea (in my view) is that 64Mb of ram is too little to make this worthwhile. I know Mr Robertson was interested in how to add 64 more (like the devboxes) but that's still a hardware modification and I can't imagine that working out when you look at the total cost of it.
The signing key used for Xbox executables is 2048 bit RSA.
That's astronomically more than most BANKS use today.. i.e, there's no way - absolutely no way - you can brute-force the Xbox signing key. The Neoproject guys are complete morons without any knowledge about cryptography. This is the third forum in 2 days I've had to post in to put some sense into this.
There are two places in the Xbox suspectible to a "no-modchip" attack - but with $100k being offered no real _groups_ of hackers are targetting this yet..
No, they didn't. A lot of different things worked together to "win" the WWII - but if I had to thank a single "thing" it would be the russian winter and russian commanders.
US helped out, together with a lot of other nations - the US did not win the war however. Each and every american claiming so only displays his/her own lack of knowledge. American historybooks are very biased though - so I'm not surprised.
No, it's not. Regarding the parent - I don't know if there are some Xboxes with an older BIOS than 3944, although I doubt it. Since I don't know that I can't say he's wrong either. It's theoretically possible, and Microsoft techpeople flashing the TSOP would then be a correct solution.
Where the arrow is pointing, there are 2 small squares of solder, you want to bridge the 2 squares together by dropping a small amount of solder between them.
The devboxes can be flashed - the retail boxes cannot. When it comes to the Xbox, as I wrote, I know what I'm talking about. Want me to show you where the two points need to be connected in the retail boxes to support flashing too?
(The devboxes also contain twice the amount of RAM, other than this, there are no differences)
(I'm one of the Xbox-hackers. I know what I'm talking about here)
The connections needed to flash the internal flash rom from a program running in the Xbox are NOT CONNECTED. It's possible to connect them if you open up the Xbox and solder yourself - but a virgin Xbox CAN NOT have it's BIOS flashed. Not by you, not by Microsoft.
Not all, but some, XboxLive games are going to cost in addition to the XboxLive fee. This is not exactly breaking news - but something conviniently left out as soon as people start comparing XboxLive to the PS2 or GC offerings.

No it's not - but it's a lot more probable that the universe cease to exist right now, in comparison.
Maybe you should read up on how long it would take to brute force a 2048 bit RSA key.
Fanboyism on Slashdot?

ZIP is easy to crack. 3 32-bit keys - password doesn't matter.

You do know there are other countries except US, Afghanistan and Iraq, right?

Just a little FYI

Ah, whattaheck. Here's a link to a turorial in this reply to:

Now do the same for the bottom of the board

That will enable write access to the tsop.
Ask yourself why I mentioned the Polish cryptographers.
Study what Russia did.

Updating the dashboard and flashing the TSOP are two very different things.
Thanks for supporting my point.
