142w ago - Earlier today we reported on the open-source PS JailBreak PS3 exploit from Mathieulh's PlayStation 3 hacking team dubbed PSGroove, and as promised the reverse-engineering details are now available linked above and posted below, as follows:
Analysis of the PSJailbreak Exploit
The PSJailbreak dongle is a modchip for the PlayStation 3 that allows users to backup and play games off the harddrive. Unlike the modchips of the Previous generation, or the modchips so far for the Xbox360 and Wii, this modchip simply plugs into the USB port on the front of the PS3, avoiding the need for complex soldering and voiding of your warranty.
As the time of writing this document, the final PSJailbreak has not been released, but a number of samples were given out and at least one fell into the hands of someone who owned a USB sniffer.
This analysis of the exploit is based on those USB sniffer logs, issues encountered during the development of the opensource PSGroove version of the exploit and a number of educated guesses. It will probably be updated as new information comes in.
The initial analysis by gamefreax.de suggested that it was a Stack...
142w ago - A few days ago PSJailBreak Reverse-Engineering work began, and today German site GamerFreax.de (linked above) has posted a breakdown of the PSJailBreak, how it was reverse engineered and notes that it requires additional hardware to update.
Below is the rough translation of the PS JailBreak reverse-engineering details, to quote:
"We have the PSJailbreak dongle yet again brought out of retirement to put it more precisely Herbs to take a closer look. We tell you here in brief the main steps of the internal process of PSJailbreak.
We can confirm that it can not confirm that PSJailbreak a clone of Sony's "Jig" is module. PSJailbrak is an exploit honest self-developed. The chip is not but a PIC18F444 ATMega with software USB.
This means the chip is internally capable of USB to emulate. PSJailbreak mainly be emulated 6Port a USB hub connected to a specific end USB devices and then disconnected. One of these devices has the ID of Sony's "Jig" module, which means that played in the development of PSJailbreaks the "Jig" module, a certain role.
But let's start at the front: When the PS3 is clamped in the USB emulation device, which has a much too big Configuration Descriptor....
