PS3 XDR-DRAM vulnerability

Developer Zecoxao, has found a new vulnerability for the PS3. It’s a hardware vulnerability available on all PS3s(Yes 3k and 4k too :P)

He found out that the serial data line on the PS3s XDR chip is used to initialize the RAM’s test pattern + it has read/write mode and is freely accessable.  😀

Here’s what Zecoxao said about the release:

in all ps3s, there is a serial data line on the console’s XDR chip used to initialize the ram‘s test pattern.
It has read/write mode and it’s freely accessable.

the address is obtained from the xdr interface.
You can see it on service manual.

You can write a payload to memory and on a loaded game (or savegame data) it’ll run the payload and do… stuff.

ps: yes, all ps3s

discuss at will or shit on it, i don’t care…

He also posted some pictures of the chip and where CMD, SCK, SDO and RST can be found.

I’m curious as to what is going to be done with this 😀
Maybe we can get CFW on 3k and 4k but that could take some time and no one knows what Sony will do about it.

  1. Since this is a hardware hack and a new one at that it can be exploited on the newest firmware I hope. I know there’s not much info, but having just updated right before reading this, I feel like a dummy dumb. s

    • I don’t see why it would not work on the newest FW

      • Sweet, so the only thing that can get rid of this exploit, if it works or when it’s working, is another hardware revision which would most likely not happen.’

        I hope the dev of this isn’t discouraged over this due to it being a hardware hack. I understand why software hacks are more popular for PS3 hacks now a days since the scene isn’t that big now.

        Does he/she accept donations?

  2. Maybe load a dumper to get the console keys to unlock FW for downgrade.

    • Why only use the Keys to downgrade :P?
      Why not use the keys and make a 4.70 CFW 😛

  3. is there any news? Does he began work on the firmware?

  4. How process going – May ba some tech info? Any details – very interesting.
