PS3 is Hacked by George Hotz - Hello Hypervisor, I'm GeoHot!

249w ago - The PS3 is hacked, at least according to [Register or Login to view links] on his latest blog entry (linked above)!!!

This news comes just under a month after he resumed PlayStation 3 hacking!

To quote: "Hello hypervisor, I'm geohot

I have full read/write access to the entire system memory, and HV level access to the processor.

In other words, I have hacked the PS3. The rest is just software. And reversing. I have a lot of reversing ahead of me.

Took 5 weeks, 3 in Boston, 2 here, very simple hardware cleverly applied, and some not so simple software.

Shout out to George Kharrat from [Register or Login to view links] for giving me this PS3 a year and a half ago to hack. Sorry it took me so long

As far as the exploit goes, I'm not revealing it yet. The theory isn't really patchable, but they can make implementations much harder. Also, for obvious reasons I can't post dumps. I'm hoping to find the decryption keys and post them, but they may be embedded in hardware. Hopefully keys are setup like the iPhone's KBAG.

A lot more to come..."

First of all, there is some key, let us name it "Official content key". Sony has ENCRYPTION for using to encrypt their games, demos, content and so on. It is not stored inside PS3, only Sony has it.There is simply no point storing it inside PS3. PS3 decrypts this content with DECRYTPION key.

There is "HDD encryption keys" which are different from the ones mentioned above and BOTH of them are inside PS3 (as PS3 decrypts and encrypts this type of content within the system)

Correct me if I'm wrong.

All that is needed is whatever the ps3 has. Using a different encryption would mean the ps3 with its decryption method could not use it.

My question now is: can the decryption key be used to encrypt data? I guess those are two different keys, right? I mean, the PS3 uses its own individual private key to encrypt stuff like, say, the HDD. And it uses a public key, common to every console, to decrypt data and perform checks.

So, my question is, the key used by Sony and game devs to encrypt and sign data, like a FW update for instance, its not present in the console, is it? So how could you actually create legit applications?

Is it just me ? but I'm picking up that geohot is not 'excited' by this anymore ? Either that or he is curbing his enthusiasm as Sony are on to him. Either way, I hope he achieves his goals.

If keys allow you to create essentially legit applications what would stop the hack from being software only? getting at them is the hard part but like the iPhone situation it could really be software only.

If someone writes a CFW that the system thinks is legit and an updated version...

As for the Slim x OtherOS question, way I see it there are only two reasons why Sony could have removed OtherOS from the Slim line: 1) changes in hardware made it impossible for OtherOS to run; 2) OtherOS can be run on a Slim PS3 but was removed for security reasons. In both cases I guess Sony would've made it impossible to install OtherOS on a Slim PS3.
