February 25, 2009 // 9:15 pm - Update: It's now confirmed as a fake guys.

Today Spanish PS3 Developer DemonHades has announced news that they may have decrypted the Sony PS3 HDD. We will update the 'rumor' status of this when more questions are answered of course.

Several PS3 Devs including NDT are currently investigating whether the method can be repeated in other PS3 consoles, or just for one console only (possibly brute-forced?) as it's already known the key differs between each.

Below is a picture of a font on the PS3 decrypted, followed by some preliminary (roughly translated) details:

The key is 512bytes is a sha1-4096 (512 bytes per sector). The key is xoreada own... To be sure it was not a simple xor as speculation... text still appears ... /cell_mw_cfs and more text:

Ps1SaveData
PspSaveData tb
PspSaveData.parentalLevel
PspSaveData.broken
PspSaveData.timeModified
PspSaveData.size
PspSaveData.sdTitle
PspSaveData.detail
PspSaveData.backUpDirName
PspSaveData.tmpDirName
PspSaveData.param1
PspSaveData.param2
PspSaveData.param3
PspSaveData.param4

The method I can/should I even say it is very close to an update could change the key or decryption/encryption. The first is to investigate all of its content and then go looking at what interests us is that we have to go 40gbs decoding one by one and is not easy.

But since you said that all the published info that this method allows for and is something that decode the hdd, as advice... I will not make an actualizar. It's about read PS3 hdd content (512 bytes xored key has been decoded), by the moment this means that hard disk content could be read, but not all info about this have been revealed.

Rumor: PlayStation 3 Hard Disk Drive Decrypted?

thanks for your answer

it may sound a little bit crazy but i want to know if there is a chance to make a private key from the public key ?.

thanks in advance ...

Still I think being able to decrypt HDD (and possibly add stuff in correct way) opens a door to many possibilities. Suddenly many people could start tinkering around looking for holes. I just hope this is not some sort of fake...

Well, we have discussed all of that before in previous development posts.

Simply put, what stops is the "flags" in the EID, and we can not change said flags as the area that they are in are signed. So , even with a decrypted HDD (assuming the EID is stored on the HDD now, which it probably is not), the file would still be signed - useless to modify!

But... could it be possible to modify somehow the migrated NAND data from the HDD in order to turn a retail console into debug?

Well, in theory, with a fully decrypted HDD, it may be possible to take a closer look at the inner workings of the PS3.

Furthermore, it would be quite easy to distribute downloaded games (PSN) to others, assuming that the DRM was also (somehow) copied over.

The DRM may be stored in the system database, which (like everything else) is on file somewhere.

The question is, is that file still encrypted?

However, we will not be able to do any unsigned code from the HDD with this - as the system will not allow unsigned code to run from the HDD.

More interesting than knowing whether Demonhades is trustful or not is the question, what can be done with a fully decrypted HDD?

Could somebody clear that question?

We will have to wait for DemonHades to post more proof in the form of files that have not been previously dump'd from dev consoles etc etc
