iQD: PS3 is Hacked - The Urban Legend Continues


Sponsored Links
243w ago - Below is iQD's statement regarding the recent GeoHot PS3 Hack news, partly it really seems as if he does not read any docs :P

The most he claims to be surprising is mentioned in the IBM docs hehe^^

To quote: "So the PS3 is hacked ? Well that's nothing more than an urban legend.

Altough it's nice to capture all these HV calls and stuff from a plain (not encrypted) lv1 binary, but this will never lead to a hacked PS3.

Let's have a look. The major security architecture on the PS3 is called the "Secure Processing Vault" and is the most important thing regarding "hacking" the PS3.

There is NO WAY for the PPU or even the HV to gain access to the SPU, which is an application running inside of an isolated SPU.

Well you can kick out the isolated SPU, like geohot mentioned, but this gives you nothing, as ALL the encryption and execution of applications (HDD encryption, app encryption, decryption, executing, signature checking, root key extraction) happens inside the isolated SPU.

To run homebrew on the PS3 you would have to reassemble the whole functionality from the SPU inside a binary running on the PPU. For this you will need the root key.

The root key is stored in hardware (not even close to the things on the iPhone). The root key cannot be extracted by any software or hardware means and is essential to ALL encryption/decryption, executing and checking routines.

The only way to get the root key is inside of an isolated SPU, as it is kick-starting the hardware encryption facility. There is no other way to do that !

Let's just assume that geohot or some other guys are able to break into the local store of the isolated SPE. There they will just find some encrypted binaries.

The key for decryption is encrypted by the root key ! You won't get anywhere without the root key.

Let's assume that someone managed to do all those stuff from the isolated SPU on the PPU and creates a CFW.

There is still a secure booting environment. The first module loaded/bootet is integrity checked by the hardware crypto facility utilizing the root key. So you have also to address this booting stuff. Again, no root key, no booting.

So there's always runtime patching you might ask ? Not possible on the PS3 because the hardware crypto facility is able to check the signatures whenever it wants to.

And which part is responsible for this ? Exactly, the isolated SPU. So if you kick out the isolated SPU the system will not boot/run anymore.

The PS3 is neither an PSP nor an iPhone. It's the most secure system architecture of this time !

The girl behind this stuff, Kanna Shimizu, is not somebody. Messing around with this is not like saying Bruce Schneier is a n00b.

Btw.: forget about all those stories, that certain hackers are or will be employed by SONY. That's nothing more than another urban legend.

@geohot It is OBVIOUS that the HV is PPC. The Cell BE is a PPC architecture, you know ;-) Better read those IBM papers in first place !

I suppose it's time to wrap this thread up, mainly as iQD isn't here to reply and we don't want to upset those working at hacking the PS3 their own way, etc.

The next official hackers what could mess with GH is Mathy (Mathieulh&Crew) and CJ (CJPC&Dev's) if you ask me.

i agree with cfwprophet..

Well, the truth is that if SKFU+iQD ever say "i/we hacked the ps3" then the ps3 will be hacked for real.

GH is just cocking and advertising himself, he opened he's mouth too early and when he realized that he cant do much and that the ps3 isn't an iphone, he posted that he doesnt know c++ and that he cant be 24/7 on the ps3... yea right, better luck next time chummy.

I wish we could link up about 200,000 ps3's and try to brute force the keys out... via the F@H method computing cloud.

I for one understand we are nowhere near homebrew... KEYS PEOPLE KEYS... but when the day comes i'll be sure to have my 20x blu-ray burner and 100Mbit connection ready to download some stuff.
