Sponsored Links
174w ago - This weekend Sony PlayStation 3 hacker naehrwert has released a PS3 SCETool based on the fail0verflow tools, an Isolated SPU binary POC dubbed Friday and some EIDTool work in progress updates for PlayStation 3 developers interested in remarrying Blu-ray drives, motherboard keys, QA tokens, etc via Twitter.

Download: PS3 SCETool / Friday Isolated SPU Binary POC / PS3 SCETool v0.0.3 and VSH.Self Output / PS3 SCETool v0.0.4

Below are the details from the ReadMe files and Tweets, as follows:

SCETool (C) 2011 by naehrwert - This tool will see more features in the future.

Notice: THIS CAN DO NOTHING NEW, IT'S CURRENTLY JUST A REWRITE OF f0f TOOLS.

Keyfile format:

A sample keyfile is included.

Shout-outs: I think they know who I mean

Friday (C) 2011 by naehrwert - This is a POC for a isolated spu binary. Generate a self encrypted+signed with the metldr keys out of friday.elf. Then use friday.h to write a PPU application that loads the self by utilizing metldr and DMAs your console's EID2 to the shared SPU LS. It will generate the P and S block from it, that is used to pair the BD drive to the specific console. Yon can then DMA the blocks out from the LS and send them to the drive to remarry it to the console.

Communication with the SPU is done over in_mbox and out_mbox. MSG_OUT_* is send from the SPU code to out_mbox. MSG_IN_* should be written from the PPU to in_mbox. When MSG_OUT_READY arrives the PPU should DMA the EID2 to EID2_START and send MSG_IN_READY. When MSG_OUT_GEN_DONE arrives the PPU should DMA the blocks out from BLOCKS_START and send MSG_IN_DIE.

Note: this is UNTESTED but should just work

which I can generate and yes my eid4 passes the hash check

but one would need to get the aes_omac1 key to be able to check it

hmm eid4 digest is stored unencrypted

seems like there are some hardcoded eid4 fallback bytes - http://pastie.org/private/oxy580s4omh8ofbdfgj3dq

Here is a follow-up from his blog today as well for those following: nwert.wordpress.com/2011/11/29/about-spu-channels-64-72-and-73/

If you are reversing the PS3′s isolated SPU modules, you will eventually notice channels 64, 72 and 73. Here are some C functions, that roughly describe how they work:

About SPU channels 64, 72 and 73

It seems that lv1ldr is storing it’s version into a special storage area.

And e.g. isoldr reads the version from the storage area and compares it to it’s own version. If the check fails, isoldr will just stop execution.

I wonder what else is stored in the area and how long the data in it persists, so my next idea is to code an isolated elf, that allows me to specify the value written to channel 64 and then dumps the data from channel 73.

Yep. WE mortals don't do nothing with this stuff. But i suppose it's an advancement about a free solution...

Oh, some news: And no, I won't release eidtool. If you want the algorithms, you'll have to start reversing

Cool, we can close this chapter too
