xorloser has tweeted about a new GitHub project to reverse the PS4 WiFi/Bluetooth firmware.
The PS4 uses a hardware module codenamed torus for its wifi and bluetooth. Currently there are two different versions of this; the older torus1 and the newer torus2. The torus firmwares are stored in plaintext on the PS4's flash. The PS4 loads them into the hardware module. This is not going to lead to some magical hack of the PS4, its just fun to poke around inside it to see what it does.
Back in January 2014 I discovered this unencrypted (plaintext) area within the flash, and confirmed it was Wifi/Lan/Bluetooth firmware, you can read about it in the forum here. The idea then was to emulate the flash circuit in an FPGA or similar, and inject code when the Wifi/Lan/Bluetooth circuit loads the plaintext firmware area of the flash, but at the time I had no PS4 so the project ended there.

My old topic about the unencrypted part of the flash is here.
