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.
