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

266w ago - The PS3 is hacked, at least according to George Hotz 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 iPhoneMod Brasil 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.

A programmer of a great studio said some months ago in an interview.

"i dont think that games piracy is a big problem, because poeple who burn those games does not belong to our main target group".

i think its 50% truethness in that. if people burn games, then they are not 100% interested in the games, or they are to dumb to understand that games who are great needs to be supported.

for myself i cant say that i allways played legal copys. but if i like a game, i buy it original. online mode, multiplayer or what ever. i want to play it with other people if i like it.

best example. command & conquer. i own all titels (the first two times O.o) and i would never burn one of these games because the guys do a great job and deserve to be supported by my money.

i can only say, i hope that the ps3 doesnt get a backup launcher, or sony implements a system that every game can only be locked on ONE account with a serial.

if you're able to modify HV code, why don't you modify your interrupts? this way you modify machine check (0x200?), illegal address translation (0x300?) and illegal instruction (0x400?) to output you the last accessed addresses. evade the problem of rebooting everytime :P

Saw two intelligent posts here @Cameron and @uf6667. Awesome idea with the interrupts! Will try it today.

Filtered out from the JUNK

I don't think Sony builted a 2 differnts kind of consoles... i think it's like the PS2 Fat and slim, same functions, just smaller sizes...

I think that many sceens could be open with a "real understanding" of the internal structure (software) of the ps3 sistem...all we have to do now is just to wait for something new or just try to be "usefull" if we know something about programming and dev!
Bye

So then when sony send out an update to ps3.. do they have multiple versions of the update for each model or one file with all info... and further more... if there is one universal update.. when installing it/updating the ps3... is the install the same on all models or do the install vary and pick out only thing it uses depending on it's hardware model... (ex. slims leave out the the ps2 play and other os)

As for keys, wouldn't all the updates also have to be incremented the same way.. with a master key so that all models can use them?

Personally I only bought a 360 because I can download games. I buy the games that I know are worth it and burn all the others. I have owned the ps3 from the beginning and only own 5 or so games. i've had my 360 for less than a year and already own 8 retail but have all the other interesting ones. I have two controllers for the ps3 and 4 for the 360.

I bought the $100 hard drive and subscribe to live, my son is the only one to play the ps3. I don't even waste money renting ps3 games. geohot is the only reason I bought an ipod touch. I hate apple and their business practices. but they made a great piece of hardware and geohot opened it up, so the way I see it sony will be getting more revenue (from me anyways) by not fighting him too much.
