116w ago - Today PS3 hacker Mathieulh reports finding a PlayStation 3 Firmware 3.56 exploit, although he states he has no plans to give any further details about it.
To quote from PSX-Scene (linked above): Well-known hacker Mathieu Hervais has reportedly found a bug that allows exploiting metldr, the bootloader and firmware version 3.56. Unfortunately, he refuses to release it.
I hesitated a lot before tweeting about it, but a bug allows exploiting metldr, the bootloader and 3.56+. I don't intent to ever unveil it.
So much for "unhackable" PS3s though... I am not giving any further details about it. Sorry.
Actually the revocation list exploit doesn't allow you to exploit isoldr, you could however sign a revoke list if you had the revocation list keys and knew the sign fail, and use that to dump isoldr. Metldr does not load revocation lists.
This has been tested, how do you think I could release the lv2ldr and appldr keys ? (about 24hrs before Geohot showed up with metldr keys) This has been tested, how do you think I could release the lv2ldr and appldr keys ? (about 24hrs before Geohot showed up with metldr keys)
You can also dump any loader using a signed metadata (including metldr) though that means you need to have the keys for it in the first place (kinda kills the purpose)
Your entire purpose is to get the isolated process (the code running inside the spu) to jump to your instructions
For exemple the following instructions will dump the isolated LS to the SPU mailbox:
Of course you'll need a ppu payload to fetch the mailbox data. Metldr is trivial to dump now that you can sign your loader, but I wont say anything more on this.
Finally the problem with isoldr and the revoke list exploit isn't so much that the exploit doesn't work (it actually does) It's that the payload from the crafted revoke list overwrites isoldr keys (which kinda kills the whole purpose), You can however get the revoke list keys from lv2ldr or appldr using the revoke list exploit and then sign a revoke list metadata to exploit isoldr later on. (There are other ways to get isoldr though, including the 3.60+ exploit I have (but there is at least another I know of) Again, good luck in your endeavor.
There is more than one npdrm key. It's not been released because the ones who have the skills to do it do not remotely care about pirating PlayStation store games (obviously).
Finally, in related PS3 homebrew news today a PS3 FW Downloader application has been released which includes Official PS3 Firmware 2.50 - 3.55 and has Geohot, Kmeaw, Wutangraz PS3 Custom Firmware and 3.55 Downgrader support.

Nah, Gehot proved that he was reliable in the Apple scene, can't doubt about that. The kid has talent, but he has a huge ego too (who wouldn't ? you're an hypocrite if you say you wouldn't do the same with his talent).
The lamers of this scene are mathieulh and his little friends. He keeps stealing work from others and pretending he did it (we never saw him release something once, never, just pretend it's his work when something got leaked).
Stabbing Geohot in the back after everything he brought to the scene, i find it pretty pathetic. At least he brought results and wasn't playing drama "i will release ... i won't release... oh i may release ... finally i wont, LOL"
This kid also had balls to go in court with Sony, say anything you want but i doubt you have even half of his courage and couldn't do the same (i dare you to say the contrary).
He fought for the scene against a huge company that could have whipped him with a finger. 90% of peoples blame him, but in his situation they would run under their mom's skirt like cowards.
At least he released something, half of devs in this scene are either drama queens with small tool or big mouthed kids who think computer engineering can be mastered for breakfast.
