Continua l'hack su PS3

Dopo una piccola fase di stallo Geohot ha scritto un nuovo post sul suo blog trattante l'Hack PS3. Il nuovo post tratta del fantomatico homebrew per l'hack alla console di casa Sony sfruttando l'unico exploit ad oggi trovato. Al momento non abbiamo notizie più dettagliate ma continueremo a tenervi informati! Stay tuned.

Post in inglese:

On the Isolated SPUs
Today I verified my theories about running the isolated SPUs as crypto engines. I believe that defeats the last technical argument against the PS3 being hacked.

In OtherOS, all 7 SPUs are idle. You can command an SPU(which I'll leave as an exercise to the reader) to load metldr, from that load the loader of your choice, and from that decrypt what you choose, everything from pkgs to selfs. Including those from future versions.

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.

Ah, but you still didn't get the Cell root key. And I/we never will. But it doesn't matter. For example, we don't have either the iPhone or PSP "root key". But I don't think anyone doubts the hackedness of those systems.

I wonder if any systems out there are actually secure?
