Living legend Shawn Hoffman @shuffle2, who extracted all keys from crypto processors of all video game consoles, talks at #TheSAS2024 about hacking PlayStation 5 chips
There are a few ways on PS5 to defeat HV. One of methods that I've found was related to APIC: struct apic_ops is located in RW segment of kernel data. With KRW you can overwrite a function pointer inside it like xapic_mode and get into ROP, for example (just need to bypass CFI).
By the way, it's not the method that has been patched in 5.00. Actually I'm not even sure if has been patched at all, needs testing for which I don't have spare time now. Maybe someone can do it.
Hello, folks. I'm in Serbia/UAE nowadays and looking for new job opportunities in info security. Remote jobs are currently preferred. CV: github.com/flatz/cv
On 4800s the Nuvoton chip marked 5565D-M was used as multi-controller. Unfortunately, there is no datasheet for it and its pinout very differs from all public datasheets of similar chips that I can find.
After a week of guessing, bruteforcing, reflashing BIOS (where I put my PSP payload) and observing LPC bus using Logic Analyzer, I was able to find a combination of register/bits that needed to be toggled to activate UART.
