[PS3] XorLoser Releases PS3 Exploit Toolkit

Notorious XorLoser has fully rewritten GeoHot’s PS3 glitch attack programs, that allow more convenient exploiting. He names it XorHack.

It allows you to call lv1 syscalls (level 1 system calls) from a normal (userspace) program. It also lets you run the software required when triggering the PS3 exploit from a normal userspace program. To give an example of how it can be used I have included the following example programs:

  • ps3exploit – Runs the software required to exploit the ps3, it loops a number of times which can be specified as a parameter. (This still must be used along with the “button pressing”, it will not exploit the PS3 via software alone).
  • dumphv – Dumps the hypervisor to a file in the current directory.
  • dumpbl – Dumps the bootloader to a file in the current directory.
  • dumprom – Dumps the system  rom to a file in the current directory.

[PS3] GeoHot Opens All HV’s SPUs / XorLoser Preps Manual

Obviously notorious George Hotz has managed to get all 7 SPUs of the Playstation 3’s CPU under his control. This means although he cannot access the CPU’s root key, he now can decrypt everything that’s going thru these SPUs like datastreams of (encrypted) commercial games.

The PPU is higher on the control chain then the SPUs. Even if checks were to be added to, for example, verify the hypervisor before decrypting the kernel, with clever memory mappings you can hide your modified hypervisor.

In the meantime another hacker going under the nick XorLoser has released a more detailed manual of how to use GeoHot’s exploitation files and how to do the glitching.

Besides that XorLoser maintains a plugin for reverser’s beloved Interactive Disassembler (IDA) that contains special PPC instructions for Xbox360 and PS3.

Congratulations to GeoHot. Kudos fly out to XorLoser.

[PS3] Infectus Chip downgrades Playstation 3 Firmware

The first mod chip has been released a couple of days for the Playstation 3 (PS3). It allows installation of any firmware revision you prefer for your best gaming experience, means you can up- and downgrade to whatever firmware you like (see video below). And no: it does not allow playing backups of your games. Even if you could afford a blu ray burner you cannot backup PS3 games currently.

The interesting point is: this chip is platform independent and can also be installed into Nintendo’s Wii or Microsoft’s XBOX 360. Since we don’t know for sure about the legal situation for such a mod chip in our beloved Germanistan, we will not include any links in this article. You know how to find, otherwise you would not be here ;-) Thanks for your understanding.
