GeoHot further progress with the isolated SPU's

**backstar** · 02-13-2010,07:51 AM

Sounds like Geohot's made real significant progress now, infact it sounds like he may have nailed it:

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?

Now, as George so aptly put it in his Twitter posting, "Where's my homebrew at"?

Thanks "Backstar" for making this post.

@FrankTheBunny - Sorry I deleted your thread, afterwards I saw you were first in posting.

I moved this thread to the "Front-Page", so it will get more traffic.

Unlike you great guys in down-under, we Canadians were sleeping this morning, so thanks for making the post regarding Geohot's latest update!

I am looking forward to what xorloser will be publishing next.

No problem, its just good that we've finally got some real progress happening.

As for whats next, I hope I'm not getting ahead of myself, but I wonder if this all means we'll see someone boot a modified/patched gameos from otheros sometime soon.

Edit - Yoshi, Geohot's been talking with the hypervisor for a while now already...
