L'application Facebook retirée car contenant une faille ?

Soumis par Attila le lun, 27/02/2012 - 00:03

Comme vous le savez peut être, l'application Facebook pour PS Vita a été retirée du SEN/PSN. La raison officielle parle d'erreurs de connexions, mais selon nabnab, l'application permettait de lancer du code non signé (AKA permet d'hacker la PS Vita !!!).

Toujours selon nabnab, cette application Facebook n'est pas la seule contenant des failles et un gros défaut de la console serait une trop grande liberté accordée à l'USB.

Nabnab indique aussi que Sony est en train de retirer le support du MIPS sur la console. Le problème serait que le VHBL (le HBL Vita, le Hack annoncé par Wololo) aurait besoin de ce support pour fonctionner, et que par conséquent, même sans diffuser l'exploit, Sony pourrait déjà avoir corrigé VHBL dans sa prochaine mise à jour, sans même connaître l'exploit.

Sony est en train de convertir toutes ses applications vers le format ARM natif.

On the new firmware, the debug usb mode work differently (the key button doesn't work on it) That you need to use a mechanism that exploit the ioctl to call the debug usb mode and more ;)

CMA use specific point and include secret key ;) the unique key of your PS Vita are save in a special cache on your Windows for example and as you can see if you check the key of CMA on your windows reg, you can find that the CMA work in read-only mode that you can't modify and only Sony can modified this (this is pretty illegal, it works like a spyware/malware that let Sony control your computer) anyway this can be fixed, check your reg ;)

For now, i need to keep that secret for while but i give you some clue ;)
When you connect the PS Vita to your computer (use a USB Log), i already explain that before but i do again, the PS Vita try to connect to the Sony server by the help of CMA Application (globalsign server also) that confirm everythings is ok and updated.

Open CMA.exe with a hexa editor and copy all the http/https and add them into your hosts file.

if you want to exploit your PS Vita, again, check into the ioctl !! it's important ever kernel Unix or Win NT use this for the USB rooting

About Facebook App on the PS Vita recently retired
One of the reason was maybe because the Facebook App allow us to run unsigned code on the PS Vita (ARM Code what's up)

This was a badly fail but don't worry, i can say that the PS Vita is already so open (i don't like to use the word hacked) but Open is better to represent how the PS Vita offer more information than what we are thinking ;)

Also to my friends that made VHBL, better to release that now before the update 1.65/1.70
Sony already know and would release a cutie update to prevent this thing (remember not anymore MIPS Wrapper and welcome ARM native program)
