Well the big PS3 Exploit talk is now officially over at the annual 27C3 conference. All the big names in the developer scene world was there giving a one hour talk regarding Sony's EPIC FAIL

But basically they talked about how the PS3 totally failed in security, by botching the pki implementation it became possible to calculate the keys needed to sign everything. PUBLIC PRIVATE KEYS, and replacing the "revoke-list" with super-large one (overflow) during the bootup NOR flash at startup, giving them full control of the PS3 system.

The 360 console is now more of secure system then the PS3 after all these years!

"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."
@KushanTheCat our goal is to have linux running on all existing PS3 consoles, whatever their firmware versions.
Our current PS3 goal: AsbestOS.pup
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
Myth: Geohot -> Sony pulls OtherOS -> JB -> Fail. Fact: Slim had no OtherOS -> Geohot -> ... . Geohot started his work due to the Slim.
@You must login or register to view this content. yes, we'll release all our tools as soon as we cleaned them up in january or so.
Great news for all PS3 User's

Complete rubbish patches of games utilize only certain aspects of the game such as call of duty black ops online multiplayer.
All of the code is stored on the disk and if they changed the way the PS3 reads the code or changed the signiture the ps3 would throw back errors.
All new disks would have to re issued.

Actually no bro, the CoD4 save isn't signed by Sony. It's patched because I'm pretty sure it has something to do with how the playlists check the save. Or maybe its something to do with how the executable checks the save. I'm pretty sure its the latter.
But, WaW and BO savegame hacking, anyone?
Maybe, amazingly, no savegame mods for either game are patched on PS3. I highly doubt it for both of them though.

DO you actually think that they didn't think about savegame mods in the development ? lol.
We are starting to under estimate treyarchs ability.
