282w ago - This weekend GeoHot, the hacker responsible for several Apple iPhone hacks, has returned to Sony PS3 hacking after his initial announcement a few months back and has opened a PS3 hacks blog (linked above).

He recently made this Tweet:

"I just pulled everything from the USB bus... http://pastie.org/757313 the Cell processor SPI bus, PS3 is going down :-)"

These are the latest posts on his new PS3 hacks blog:

Cell SPI

The Cell processor has an SPI port which is used to configure the chip on startup. Well documented here. It also allows hypervisor level MMIO registers to be accessed. In the PS3, the south bridge sets up the cell, and the traces connecting them are on the bottom layer of the board. Cut them and stick an FPGA between.

Quick theoretical attack. Set an SPU's user memory region to overlap with the current HTAB. Change the HTAB to allow read/write to the hypervisor! If that works it's full compromise of the PPU.


A Real Challenge

The PS3 has been on the market for over three years now, and it is yet to be hacked. It's time for that to change.

I spent three weeks in Boston working software only, but now I'm home and have hardware. My end goal is to enable unsigned code execution, making every unit into a test and opening up a third party development community, either through software or hardware (with a mod chip). The PS3 is a prime example of how security should be done, very open docs wise, and the thing even runs Linux. But it isn't unbreakable :-)

If someone/some group doesn't find a hack, there's always next year. What sucks is only time will indeed tell, but time is the only important resource we have as a species, and it is the most limited one too.

He may make a breakthrough that may help, or he may not. This might just not be his area, who knows. Only time will tell :]

Is there any 360 Dev Team's or Dev Team members trying to hack the PS3 as well? or are they too fanboyish?

You should do another simple search on google and you will find the correct answer easily.

The new batch of 3GS phones since October 2009 have the new bootrom. this will cause JB to be lost after a reboot. The correct term for this current condition is called "tethered JB". The phone appears in recovery mode but can easily be recovered by plugging into the PC and run blackrain again. After that, your phone goes back to normal. This only happens when you reboot.

All iphones prior to October have enjoyed "untethered JB" which remain permanently JB'ed.

To know if you got hit with the new bootrom, you need to check production dates. They are always located in your serial number starting from the 3rd,4th and 5th number.

3rd number represents the year, so it should be a 9 for most 3GS. The next 2 numbers represents the weeks out of 52. e.g 930 means 2009, 30th week. 30 divided by 4 weeks = around 7th month july. so the unit was manufactured around July 09.

The threshold is believed to be 940 when the new bootroms arrived.

Isn't this suppose to be about hacking the PS3

I agree with you. However I had the same feeling with the iphone, and each time I thought nobody would JB it again, he came back and did it quite quicly... That's why people are counting on his talents to do the same for the PS3... That's idealistic I know . But people like hope!

I just made my first steps in the dev section of the forum and would like to thanks all those devs who spend a lot of time on this damned machine who definitely don't be hacked.

Concerning Geohot, I saw something on his twitter this morning making me think he's still working on the PS3:

These forums will burn!

Agreed.. then we will have to call in firefighter CJPC to put the flames out.
