* The flash is encrypted with a per-box key
* The key is stored inside the CPU
* The boot ROM is stored inside the CPU
* Also inside the CPU is a hypervisor that verifies the running state of the kernel, making sure there is no modification (RAM checksums), else the Xbox360 panics and blows up!
* The CPU contains RAM inside of it to store the checksums
* All interrupt/exception handling is done by the hypervisor
* All code runs in kernel mode
* The emulator for first generation games can be updated via an official Microsoft download burned to CD by the user, though the CDs' content will be encrypted and signed with public key cryptography.
The Xbox 360's Hard Disk appears to connect to the Xbox 360 via 7-pin SATA, internally the drive connects to the external connector through standard SATA data and power connectors. This should be of some help.

Sounds like a tough cookie.

Holy fucking paranoid.

It's a black box that's full of trip wires.

Sure, people might have their ISO's today, but from the sound of that, it might be a long, long time before they're playing them.

 

[antispin]

Guess I won't be abusing the 360 as much as I did the first one, at least for a while. Wonder if the backward compatibility will open a backdoor.

 

[xexex]

it'll be cracked. no doubt.

 

[mrklaw]

I wonder if XBMC is backwards compatible

 

[M3wThr33]

Ooh! Standard SATA drive! That'll be the key, eh? Find a buffer overflow in a gamesave, load it onto the 360 HDD...

 

[Mupepe]

what is all your problems? if you really cared about the gaming industry you wouldn't exploit the systems like this. you all talk about what's wrong with the industry when in fact it's yourselves.

On cloudy days, that high horse of yours probably obstructs your vision. Watch out.

 

[antispin]

must. destroy. gaming. industry.

 

[The Faceless Master]

guess that explains why they're confident enough to release a burnable emulation update... the 360 sounds damn near invincible!

 

[Timen]

there will probably be just one jumper setting to bypass the whole thing.

 

[Ghost]

Cant wait to see videos of 360 self destructing.

 

[Deleted member 1235]

this points out how awesome the original xbox was. Might have to pick up a modded one again.

 

[FiRez]

It seems that the problem isn't only replacing the BIOS this time
even if someone suceeds replacing it, there are a lot of cheksums hardwired to not let it running.

Well done. Down with filthy pirates

 

[Apharmd Battler]

ith all those traps you'd have to be the hacker equivalnet of a master lockpick and bomb defuser. :lol

 

[Hajaz]

modchips have become big business though. i imagine some of the teams have millions of $ at their disposal just from their xboxchip sales.

In the end, if its electronics, it can get hacked. It's all a matter of how many cash/time the hacker is willing to spend on it.

But the more complicated it gets, the fewer people will bother to do it.

 

[teepo]

the mod scene is bigger then it ever was.

it'll be fucked.

 

[Sullichin]

Good. Less people on GAF saying how cool it is to play MAME games on 360. :lol

this is flawed logic. everything can get hacked, but the major point is how long it takes to hack it. If it takes more than 5-6 years to hack the xbox 360, after which the system will be irrelevant, then it can be called a secure system. And one xbox 360 being hacked, doesn't mean anything, if they can't replicate it in an easy way like with the Xbox. MS has learned a lot from their mistakes from Xbox. I find it surprising that everyone thinks that it is a given that it will be hacked.

 

[pringles]

No more online games ruined by modders? Please god let it be so.

 

[Hurricane_Chris]

I remember some hard to do GC exploits...but was/is there one that's relatively easy to do today?

 

[DSN2K]

it was never a matter of if but when.

 

[The Faceless Master]

I remember some hard to do GC exploits...but was/is there one that's relatively easy to do today?

yeah there are exploits that load alternate loaders and quite a few modchips too

 

[Leo the 3rd]

No one makes a lock without a key. Give them time and they'll figure it out.

 

[truffleshuffle83]

anything that is digital will be hacked...there is no doubt theyll do it, now how long it takes is the question???

 

[shuri]

That's certainly incredible. But it only takes a single flaw.

 

[Animal]

If Microsoft is smart, they wouldn't make it impossible to crack. Instead they would focus on not making it worthy for someone to do so. In other words the end result is not worth persuing.

Think of it this way:
We all already know there are numerous system security redundencies in the 360 hardware and software. If Microsoft is intelligent, they would have put enough so that any code that is forced upon it would be using most of the computing power just to simply get by the safeguards and not executing the code. A possible sign of this is the framerate hits that xbox1 games are taking while being played on the 360.

So in the end, yes its possible, but will it be worth it?

 

[datruth29]

QFT. That's how it is with security anywhere. The defender has to prepare for everything, while the attacker only has to find one thing.

 

[emerge]

What if there are no flaws? The security design of the 360 is far beyond the original Xbox, which implemented security through obscurity. X360 probably using a TPM implementation and public key infrastructure is another game.
