PS3 'Private Key,' Enabling Unauthorized Code
UPDATE: Some tools for ps3 files. Expect some fail, this is still WIP. Check it out here: You must login or register to view this content.
UPDATE:
UPDATE: Sha1 hashes for some keys
UPDATE: The scam videos are gone now but the fake Fail0verflow account is still there. Don't get fooled by imposter's.
UPDATE: Watch out for Fail0verflow impersonators. They will scam you.
UPDATE: What Sony has to do to patch this! (Thanks manster)
1) Respin the hardware. There's an incredible exploit in that the verification of bootloaders loaded off the NAND/NOR is verified after they've been loaded, and then they're allowed to continue to execute. This is why ALL EXISTING PS3s on the market are from now on hackable. Really. There's nothing that can be done to stop this.
2) Design new firmware(s) that contains the infamous "whitelist" of all previously (and erroneously) signed software, but with new keys and new signature verification algorithms. Deploy these firmwares/loaders ONLY on the respinned hardware (see above).
3) For older hardware (that is, everything already produced from the factory and on the market) release new firmware that contains the new signature verification algorithms, but NOT any of the new keys. Remember, what you deploy on the old hardware is fully transparent. Update the loaders as well, as talked about in the presentation, since that will force everyone who wants to have a still jailbroken console to install a modchip (see #1).
4) Dual-sign all new stuff. Old broken consoles will be able to run it, and the new secure model will verify with new keys. Previously signed software will only execute on the new systems if they pass the whitelist-test.
UPDATE: What Marcan had to install in order to dump/change the NOR chip. This is probably what your going to have to do.
UPDATE:
This should be released by January
Fail0verflow releases this statement about Geohot
UPDATE: Marcan @ 27C3 Lightning Talk

Fail0verflow, the hackers responsible for the Wii's Homebrew channel, gave a presentation during the Chaos Communication Conference 27C3 in which they are claiming they have figured out the 'private key' used by Sony to authorize code to run on retail PS3 systems. This could potentially give "full control of the PS3 system," without having to use a usb device. For those of you who don’t understand yet, this will make us able to sign our own files with Sony’s encryption will and allow us to create our own software/homebrew and load it without even needing to jailbreak the PS3, because it will look like a legit piece of software from Sony.
Btw: PSN ACCESS NOT YET CONFIRMED
The group will explain more when their website launches, and have planned a demo for tomorrow's conference. But what they have explained is how Sony didn't bother generating any random numbers to secure the PS3. Look at the picture below.
Read the tweet below on what this is supposed to do. As it is not meant to enable PS3 game piracy.
But don't expect to see the website launch tomorrow. Fail0verflow told Joystiq the folllowing via twitter.
UPDATE: Full presentation after the break, courtesy of PSGroove.

Every time a new full key is made it differs from the old one. They could change the key in a new firmware but include a list of the full old keys to keep the old games working. This would stop anyone making a new key because the can't PSJailBreak OR use OtherOS.

Omg with this exploit this could mean infinite possibilities, and your still thinking of running silly little game patches /facepalm

"the recent advent of these new exploits means current firmware is vulnerable, v3.55 and possibly beyond. It will be very difficult for sony to fix the described exploits."
"we can now run unsigned code on an non-exploited ps3."
myth #1: It took us 3-4 years to do this. Negative, this exploit only took a few months after we started working. We weren't trying before.
Myth #2: Sony can change keys. No, they can't. These aren't encryption keys, they're signing keys. If they change them games stop working.
Clarification #3: The private keys refer to keys that sony hq uses. Ps3s don't have these keys (but we calculated them due to the fail).
Clarification #4: The random number isn't 4, it's more like 007eabbb79360e14df1457a4194b82f71a0dc39280 (example). But it's still constant.
Note: We won't be working long-term on cfw or similar. We'll release tools and a poc, someone else can take over. The fun part is done
