Ancora buone notizie per l'Hack della Ps3!

[dennisfrau]

Il protagonista di questa notizia è un certo Demonheads, a quanto pare ha scoperto una porta JTAG sul PCB del lettore blu ray della Ps3.
Questa porta è usata per eseguire dei test o debug nelle Ps3 debug, questa porta inoltre, secondo un ultimo aggirnamento della news, risulta attiva , in teoria si potrebbe usare quindi per altri scopi come per esempio il deciframento del firmware o di un eventuale Custom Firmware come è successo per la XBox 360


Queste le parole di Demonhades:

"Last night after finishing the research meeting I went looking for information about BD integrated reader, as you know I would not support full backups but sony is screwing us over, so I think it's time to be less hesitant and think more selfishly. While checking the back of the reader PCB I saw that there are terminals without a connector, these terminals belong to a connector which connects ’something’ and through Internet I found the points used in a JTag, including the TDO, TDI, TMS etc.

"Originally developed for printed circuit boards, it is currently used for test of submodules of integrated circuits, and is also useful as a mechanism for debugging embedded applications, as it provides a backdoor to within the system. When used as a debugging tool, an in-circuit emulator that uses JTag as the transport mechanism allows the programmer to access the debugging module that is integrated into the CPU. The debug module enables the programmer to correct their errors and code logic of their systems.

There are consumer products that have a JTag port integrated, so that the connections are often available on the PCB as part of the prototype phase of the product. These connections can provide a simple way to reverse-engineer."

As you can see we have an opportunity to try to get the firmware, decrypted data, and all that is able to control the Blu-ray reader".
