Similar to GeekPwn, the CCC Conference, Zer0Con and Tencent Security Conference hacker Volodymyr Pikhur who previously shared a demo of his PS4 IPL AES + HMAC Key Recovery Project will be giving a PS4 presentation at Recon Brussels 2018 on February 3rd at 16:00. :geek:

Here are the details from their conference page, to quote:

By: Volodymyr Pikhur
Scheduled on: February 3 at 16:00

This presentation will talk about how custom Southbridge silicon, responsible for background downloads while main SoC is off, didn’t help to secure PlayStation 4.

It will explain how a chain of exploits combined with hardware attacks will allow code to run in the context of the secure bootloader, extract private keys, and sign a custom kernel.

From the Github page, to quote: REcon 2018

Mmmmmm :)

I just hope he won't be an idiot like some other devs and will publish how to do it exactly. If he managed to break private keys then CFW is cummin'. Of course that depends on how much access the ARM chip has to the system.

like where this is going, but i dont think he will give everything away like that.

once again someone else will have to do the true release

Most likely nothing will come out of this... I mean he's not just going to risk Sony coming after him, just so others could use it for backups.

He just wants to showcase the possibilities, he won't reveil his tricks!
