Sony PS3 Hacker KaKaRoToKS Confirms Exploit Still in 4.0 Firmware


Sponsored Links
142w ago - Following up on the previous article and update for the 3.73 JailBreak, today Sony PlayStation 3 Hacker KaKaRoToKS has confirmed it is safe to update to PS3 Firmware 4.00 for those planning to use the exploit when it is released.

Below are some recent Tweets from him, as follows:

FYI, tested yesterday and the jailbreak still works on 4.0 so it's safe to upgrade (for those on 3.73)

Just got my progskeet today. Thanks uf6667 for sending it! It's so small!

Not much new to go on at the moment, but keep in mind the upcoming PlayStation 3 exploit will not enable PS3 backup managers such as multiMAN or Rogero as it does not include support for modifying Peek and Poke for lv1 and lv2 as outlined in the FAQ that was previously posted.

oh I thought they found a way to decrypt the eboot and unsign. That way it would be possible to reverse engineer. Then all hope is lost hehe

Congrats Cfwprophet and nabnab, I know youre trying hard to make a better place for the scene.

We know how it works and have explained a lot of times. The dongle puts your con into debugger mode. In this special mode you can debug games and thats what they do. They use the system embended debugger to let you play those games.

They take the official game selfs from disk and dump out the elf via the sdk, then re-encrypt them as debug selfs and on a special way thats it.

But it takes a bit more work to get this for free for every one done. The keys have nothing to do with it. They use drm just to hide and to be able to milk us all a bit longer till a free version is done.

And if someone finds how it works, it should be possible of doing the same thing comparing the eboots without the keys with the ones with keys.

In cryptography, a timing attack is a side channel attack in which the attacker attempts to compromise a cryptosystem by analyzing the time taken to execute cryptographic algorithms. Every logical operation in a computer takes time to execute, and the time can differ based on the input; with precise measurements of the time for each operation, an attacker can work backwards to the input.

its a shame they all think its such a big deal.. its only video games not cure for cancer.. sure it would be great and mean a lot to alot of us but in reality its not that big of a deal, but the way they act gives them a feeling of power i guess.. i don't really understand such behavior, myself i get most enjoyment out of trying to help others..

i wish i bought an xbox when i had the spare cash.. but i love psn too much so ill stick to my ps3 and grin and bare it.. LOL

sorry if it sounds stupid, but we seem to already have the equation ecds uses, cant we extrapolate the variables using multiples ps3 on ofw 4.00 and HFW 4.00?

For what i saw the ECDS encryption only works fine if there is only one or a few machines with the same key. With multiple ps3's its possible to extrapolate, and the higher the number the easier it is.
