Besty 4 Posted January 4, 2011 Share Posted January 4, 2011 This bloke has managed to find the root keys used to sign content on the PS3, enabling people to play copies, use homebrew, etc, etc. There's a couple links on that site but not entirely sure what to do with them yet. Apparently it'll allow ALL PS3's the ability to play PS2 games as well, they all have the capability just Sony switched it off! Further updates when I find oot!

Ayatollah Hermione 13762 Posted January 4, 2011 Share Posted January 4, 2011 You're going to have to walk me through this one, Besty. I do what with what? Link to comment Share on other sites More sharing options...
Besty 4 Posted January 4, 2011 Author Share Posted January 4, 2011 I'm the same as you at the mo mate, not a clue... I'll post more when I know though. Link to comment Share on other sites More sharing options...

Besty 4 Posted January 4, 2011 Author Share Posted January 4, 2011 I'm just getting the info off others, don't have to do much! I think now that it's been cracked, they're just waiting on someone to create some custom software to be able to play chipped games. The cracks from the bloke who originally did the iPhone so hopefully it's good. Link to comment Share on other sites More sharing options...
Besty 4 Posted January 4, 2011 Author Share Posted January 4, 2011 This is a whole different ball game to MS and the Wii. Sony uses public key cryptography to ensure a game playable online is legitimate. Now, pirate games will appear legit. Sony has no way of knowing, unless they revoke the keys making every current game unplayable online and offline. Doesn't really sound good for Sony like, fuck all they can do!

Ayatollah Hermione 13762 Posted January 4, 2011 Share Posted January 4, 2011 Been looking for something like this for ages, it's far too expensive having the PS3 and the 360 and trying to keep up with the new releases. Link to comment Share on other sites More sharing options...
Besty 4 Posted January 4, 2011 Author Share Posted January 4, 2011 I used to have the 360 chipped but got caught, think it's been updated now so it's harder to get caught. With this though, seems like they can't do anything really. Link to comment Share on other sites More sharing options...
Park Life 71 Posted January 4, 2011 Share Posted January 4, 2011 Across a 45-minute presentation, the team revealed the methodology that made the on-die security an irrelevance and proved beyond doubt that the Hypervisor tech – the CPU guardian that is supposed to stop unauthorised code running – was almost completely pointless. According to the Fail0verflow team, the PS3's architecture appears to allow the execution of rogue "unsigned" code with only the minimum of effort required from a determined hacker – which seems to explain in part how the PSJailbreak exploit was able to run pirate games even though the Hypervisor was not touched at all. Based on their presentation, it looks as though the team has not cracked the Hypervisor even with the new hack, but their contention is that its application is an irrelevance anyway. Even specific code that Sony revokes and bans from use within the PS3 isn't actually being checked when it is run, so after the Hypervisor's cursory check, rogue code can be patched back in and run as per normal. However, the Fail0verflow team's work goes way beyond this traditional style of hacking. They have released the technique by which any kind of unauthorised code can be run on any PS3. Every PS3 executable file is encrypted, or signed, using private ciphers only available (in theory) to Sony itself. It has long been established that brute-forcing the keys would take hundreds of thousands of computers hundreds of thousands of years to complete. However, despite this mathematical reality, Fail0verflow are now in possession of all of the encryption keys Sony uses. They can create DLC-style packages that will run on any PlayStation 3, and yes, they can create their own custom firmware upgrades. Their stated aim is to produce their own firmware update that boots directly into Linux on any PS3, but the methodology allows for any kind of custom firmware to be produced – and we all know what that means. So how did Fail0verflow get the keys so quickly? Well, in creating the encrypted files, an important element of the mathematical formula is the use of a random number. The PS3 encryption scheme uses just a single random number that never varies between each signed file, while the proper way of carrying out the signing process is to use a different random number every time a file is signed. Armed with just two signatures, it is possible to mathematically reconstruct the encryption key thanks to this constant variable. I Link to comment Share on other sites More sharing options...
Ayatollah Hermione 13762 Posted January 4, 2011 Share Posted January 4, 2011 Got a link to a guide or anything for playing the downloaded games, Ant? Link to comment Share on other sites More sharing options...
Kevin 1 Posted January 5, 2011 Share Posted January 5, 2011 no it wont work ant, presuming that the good folks of toontastic update their ps3, and to go online they must, then that tutorial will not work. it's only good for 3.40. Link to comment Share on other sites More sharing options...
