PS JailBreak Successfully Cloned by Mathieulh's PS3 Hacker Team


Sponsored Links
211w ago - Over the weekend the PS3 modchip known as PS JailBreak was examined, and today Mathieulh has made several Tweets (linked above) confirming that his PS3 hacker team have successfully cloned the PS JailBreak USB device.

Essentially this means the PS3 hack used to run PlayStation 3 game backups on a retail PS3 console was itself hacked, and according to Mathieulh details on the exploit used will be publically documented and available as soon as next week.

Those interested in acquiring the necessary hardware, specifically a Teensy ++ board or an AT90USBKEY, may want to check HERE for some handy links.

Below are some quotes from his recent Tweets, as follows:

"Someone from our group just successfully cloned the psjailbreak dongle. Going to improve the shell code soon.

We are not releasing anything, we didn't just rip things off, we know how it works, the clone is just a POC, we plan on documenting.

The exploit will be documented on the ps3wiki as soon as possible (we need to write up the whole article, will take a bit)

Buy an AT90USBKEY or Teensy board now and we'll have good news soon.

Right now as far as I know the (original clone) code has been ported to the Teensy ++ There is no ETA as to any other devices so far."

Teensy Key Features:

• USB can be any type of device
• AVR processor, 16 MHz
• Single pushbutton programming
• Easy to use Teensy Loader application
• Free software development tools
• Works with Mac OS X, Linux & Windows
• Tiny size, perfect for many projects
• Available with pins for solderless breadboard
• Very low cost & low cost shipping options

From what I understand, they will publicly document how to DIY the exploit, but they will be changing the way it works? There will now be no option to run the backup manager as I understand? What about homebrew, will that too be disabled?

well, it seems that they will only release the exploit and document it - which is something that i believe, to be the right move. They don't want to be the ones responsible for banning thousands of PS3s, if sony patches the firmware so to avoid the shell open code patching for the games backup to work and starts banning ppl.

For sure, some ppl will come up later on and with the exploit in hand, craft some new tools for backups, homebrew, etc.

This is not true, sorry. I've been disassembling the "shellcode" and it patches a whole bunch of things. One of them is specifically patching the file open code, looking for "/dev_bdvd" at the start and creating a new file path based on a prefix that's been set by running the backup manager. The hack to enable the install package option is seperate to this.

This also explains why the backup manager doesn't work on test units - because the API call the jig creates so that the backup manager can set the prefix doesn't exist yet.

Guys the jailbreak does not enable the ps3 to play backups from hdd this does the Backup Manager.The jailbreak set the flag for the console from RETAIL to DEBUG and there for you can use the Backup Manager app.

When Mathieulh's crew want to remove the Backup Support they have to remove the part to swich the console into DEBUG mode and this is crap. Why then cloning the usb modchip and releasing the code to flash onto a USB dev or demo device?To do what, not enabling the DEBUG mode and only blocking FW and PSN updates?

And even when they block the ID of the Backup Manager in the FW then we just need to change the Title ID of the Manager and here we go.

The USB dongle enables installation of unsigned homebrew software - As far as I understand it, the dongle itself has absolutely nothing to do filesystem limitations.

It is the SOFTWARE that you install with it that has limitations on it - be it limitations with the software written, or be it with the access / abilities afforded to it by the PS3 Hypervisor.

It is quite possible that in the coming weeks/months/years homebrew developers will provide software that allows for Ext2/Ext3/NTFS or any other variation of file system (Assuming this is allowed by any remaining restrictions that the Hypervisor enforces).

PS1/PS2 compatibility - If you can't currently play PS1 or PS2 games - then you're not going to be able to with the PSJB until such time as a dev writes homebrew that allows you to.

If you CAN play PS1/PS2 games (i.e. have a FAT console with 4 USB) they you will still be able to - Not sure if the backup manage that is currently available will allow you to backup those games - but i'm sure there will be a solution for those with 4USB

NTFS - yeah well it might be nice (ext2/ext3 wld be better tho! IMHO), but even if there isn't any way to read/write NTFS filesystem due to hypervisor, I wouldn't think it will be long before someone writes a new backup manager that allows for split files (e.g. File.001, File.002) which would be a very quick and easy solution to the 4gb limit.

I'm looking forward to the following:-
1. Cheap clones
2. Confirmation that Sony detection can be bypassed
3. A huge barrage of homebrew, including better backup managers, VNC client/servers, Homebrew games etc etc etc
