PLAYSTATION 3

Zwei nicht unbekannte Persönlichkeiten der Homebrew-/Moddingscene widmen sich nun dank Geohots Exploit der PS3. Xorloser, ein Hacker den viele aus dem Xbox 360 Bereich kennen hat zum Beispiel eine neue Version des PS3 Exploits released mit dem nun alle PS3 Firmwareversionen unterstüzt werden.
Modrobert, ebenfalls kein Unbekannter und Inhaber der Webseite Eurasia.nu arbeitet am PS3 Glitch Finder, einer FPGA (Spartan 3) Lösung zum schnellerem nutzen bzw. finden des Exploits.

As I’m sure everybody heard, the memory access exploit for the PS3 hypervisor was released recently by geohotz. I was finally able to replicate his hack so I thought I’d take the time to help out others who may also have trouble due to being linux n00bs like me If I were to post everything at once it would be too much work and I’d never get around to it, so I’ll post bits at a time to ensure I actually do post it heh. Today’s post will talk about the software side of the exploit.
Please note that the geohotz exploit software was hardcoded for the v2.42 firmware, I have made a small fix that attempts to dynamically support all firmware versions. I have only tested and used it on v3.15 however.

I’m working on a FPGA (Spartan 3) code project in vhdl titled “ps3 glitch finder” where you can set low/high delay via buttons and have the nano second delay show in a led display. Created a DCM (Digital Clock Manager, available in Spartan 3) primitive to get 200MHz (still using a 25MHz external crystal) so the lowest pulse possible is 5ns (instead of 40ns). This way I hope the “optimal glitch” can be found, and the design can be used for other glitch project as well.
Probably overkill for such a simple task, but it has been fun so far.
