GeoHot Update - What it is! and What it isn't!

What it is and what it isn't

First off, this is not a release blog like "On The iPhone". If you are expecting some tool to be released from this blog like blackra1n, stop reading now. If you have a slim and are complaining this hack won't work for you, stop reading now. WE DO NOT CONDONE PIRACY, NOR WILL WE EVER. If you are looking for piracy, stop reading now. If you want to see the direction in which I will take this blog, read the early entries in the iPhone one. Information on this blog is for research purposes only.

That aside, I'll tell you what I have so far. I have added two hypercalls, lv1_peek and lv1_poke. peek reads memory in real space(including all the MMIO), poke writes it. I can also add other arbitrary hypercalls as I see fit.

The hypervisor is complicated, it is written in C++ and is PPC, which I am not that familiar with yet. At first I was trying to add a hypercall to add arbitrary real memory to the LPAR, but it kept crashing(because I can't code), which is really annoying, because I have to wait while Linux reboots.

Some people pointed out that I have not accessed the isolated SPEs. This is true. Although as far as doing anything with the system, it doesn't matter. The PPE can't read the isolated data, but it can kick the isolated SPEs out. Decrypt the PPE binary you need using the intact SPE and save the decrypted version. Kick out the SPE, and patch the decrypted version all you want. And interesting note, by the time you get to OtherOS, all 7 working SPEs are stopped.

Despite this, I am working on the isolated SPEs now(which I can now load), because what I'd really like to do is post decryption keys here so you guys can join the fun.

Sounds like there could be fun for the community if he does retrieve the decryption keys

let's hope it does not happen the way AACS keys craze happened on digg :]

I wish there were enough decryption keys to reverse encryption keys.

It wouldn't be a surprise if it were like AACS stuff was.

What? No piracy? Useless.

**FoE Ender** · 01-26-2010,01:40 PM

he I saying HE doesn't condone piracy and wont make anything that allows it, that is not to say that his hack wont give others the ability to do so.

he knows full well that it does and he has already said that his hack will lead to a hardware mod not a software one which should discourage alot of would be "hackers".

One interesting thing I picked up from this post of his is a note that it wont work on slim ps3's....

**amp2006** · 01-26-2010,03:20 PM

well lets see if its gunna work on Fat first and then for the slim i am sure it will come

For people who are non technical, this article tries to explain the whole PS3hacking controversy http://www.eurogamer.net/articles/di...hacked-article

**FoE Ender** · 01-26-2010,05:23 PM

so basically unless he really has that "key" then its far from hacked. From his claims though I am guessing he found away around their measures they hadn't thought of in order to get the ps3 to do what he wants and then he just had it dump that key somehow. thats why he wants people to work with the hv...

as soon as I see a hello world I'm going to buy a used fat ps3...
